Some features and characteristics of this disclosure are related to a computer case. The brain system includes airflow channels to allow the airflow to specifically cool one or more power supply units (PSUs) in the respective power supply receiving spaces. The chassis may include a baffle device, which is positioned between the power supply receiving space and the air flow channel, for guiding the air flow through the power supply unit to the air flow channel. The airflow channel can be located between the first space and the second space of the chassis, and each is equipped with a computing component. The baffle device may include a wire passing channel to receive wires that facilitate communication between the components in the first space and the components in the second space. The baffle device may include one or more ribs, which prevents the power supply unit from being completely inserted into the power supply receiving space when the power supply unit is inserted in an incorrect position, thus reminding the user (signaling to the user) Remove the power supply unit and reinsert it in the correct position.

In some computer systems, especially those with high power supply requirements (for example, power supply units with 800 watts, 1300 watts, and/or 2400 watts or more), the airflow used to cool the power supply units must be Manage properly. In order to achieve improved cooling performance, the air flow channel can be used to establish the air flow channel to the power supply unit at the first end of the computer case, pass through the air flow channel, and exit from the second end of the case. Such an air flow channel may be a dedicated channel, which is specifically used to cool the power supply unit. Therefore, the heated air from the power supply unit can leave the case without contacting other electronic components in the computer case (for example, a motherboard, a processing unit, a memory device, etc.).

In some cases, the airflow channel is designed to have a small or minimum width, and therefore must extend upright within the chassis. In some cases, the airflow channel is best located in the center of the cabinet or spaced apart from the side walls of the cabinet. The air flow channel can therefore be The chassis is divided into several spaces, such as a first chassis space and a second chassis space. However, because of the existence of the airflow channel, it is difficult to lay cables (run cables) between the components in the first cabinet space and the components in the second cabinet space without leaving the cabinet.

For example, in some cases, the motherboard and control card (for example, redundant array of independent disks (RAID) card or host bus adapter (HPA) card) can be located in In the first chassis space, a group of storage devices (for example, hard disks or solid state drives) can be located in the second chassis space. It is necessary for the storage device to run at high speed in many computer system implementations. The storage device is attached via high-speed cables (for example, serial attached small computer system interface (SAS) cables, serial advanced technology) (serial advanced technology attachment, SATA) cable or high-density serial attachment of small computer system interface or small computer system interface cable) is coupled to the control card. Therefore, several sets of wires may need to pass between the space of the first cabinet and the space of the second cabinet.

Some of the features and characteristics of the present disclosure relate to the baffle device, which is positioned between the power supply receiving space of the chassis and the air flow channel. The baffle device may guide the air passing through the power supply unit (for example, the air in the space received by the power supply) to the air flow channel. The baffle device may include oblique, curved or other shapes of baffle surfaces to guide air to the air flow channel.

The baffle device may further include a wire passing channel, allowing one or more wires to pass from one side of the baffle device to the other side. The wire passing channel part may be formed by the surface of the baffle, so that the baffle surface is statically placed in the wire passing channel and entering from the power supply receiving space Between the air. In some cases, the wire passing channel forms a groove in the top of the baffle device, thus allowing easy access to the wire passing channel. A compressible air seal may be placed on the upper surface of the baffle device to reduce or minimize the risk of air leakage between the baffle device and any surface directly above the baffle device (e.g., the top cover). In some cases, the compressible air seal can cover the wire passage, which can facilitate preventing any wires from escaping from the wire passage. In some cases, the compressible air seal includes a sponge material. In some cases, the compressible air seal further includes a layer of biaxially-oriented polyethylene terephthalate (BoPET) (for example, Mylar®) or a similar film material that directly contacts the top surface of the baffle device, such as Improve the ability to remove the compressible air seal, which can be particularly useful when you want to enter the wire through the channel.

In many cases, the power supply unit can be inserted into the power supply receiving space in at least two different orientations, including at least one correct orientation and one incorrect orientation. Generally, the incorrect orientation is rotated 180 degrees longitudinally from the correct orientation. When the power supply unit is inserted in the correct position, the connector of the power supply unit (for example, an edge connector or a golden finger connector) can be engaged with the receiving connector in the chassis. The receiving connector may be coupled to the power distribution board, so that power from the power supply unit to various electronic components of the computer system is connected to the receiving connector. When fully inserted in the correct position, the outer surface of the power supply unit usually flushes with the case or the power supply receiving space.

In some cases, the baffle device may also include one or more ribs. If the power supply unit is inserted in an incorrect position, the ribs are designed to contact the connector of the power supply unit. One or more ribs can be removed from the baffle surface and/or the baffle device Other surfaces extend. One or more ribs may expose the collision surface toward the power supply unit, so that the insertion of the power supply unit in an incorrect orientation causes the connector to contact the collision surface. One or more ribs are configured so that the power supply unit cannot be inserted into the power supply receiving space beyond a certain insertion depth, which is smaller than the insertion depth when the power supply unit is fully inserted in the correct orientation. Therefore, when the power supply unit is completely inserted in an incorrect position, the outer surface of the power supply unit will not be flush with the case or the power supply receiving space. On the contrary, the outer surface of the power supply unit will be spaced apart from the chassis or the receiving space of the power supply. Therefore, the use of the disclosed baffle device can easily visually distinguish the power supply unit inserted in the correct orientation and the power supply unit inserted in the incorrect orientation.

In some cases, the baffle device may be made of a single piece of material, although this is not necessarily the case. In some cases, the baffle surface and one or more ribs may be formed together, although this is not necessarily the case.

These illustrative examples are given to introduce the reader to the general subject matter discussed here, and are not intended to limit the scope of the concepts disclosed. The following paragraphs describe various additional features and examples with reference to the accompanying drawings, in which similar symbols indicate similar elements, and directional descriptions are used to describe illustrative embodiments, but similar to the illustrative embodiments should not be used Limit this disclosure. The elements included in this drawing may not be drawn to scale.

Figure 1 is an isometric view of a computer system 100 with a power supply unit (PSU) 108 ready to be inserted in accordance with certain features of the present disclosure. The computer system 100 may include a chassis 102. The chassis 102 is depicted as a 2U chassis, although other sized chassis may be used. The chassis 102 may include two power supply receiving spaces arranged in a stack 106, 107, although other arrangements can be used (e.g. side-to-side arrangements). In some cases, other amounts of power supply receiving spaces 106, 107 may be used (e.g., one space or more than two spaces). For the purpose of description here, the end of the chassis with the power supply receiving spaces 106, 107 will be referred to as the back end of the chassis, although in some cases the end of the chassis with the power supply receiving spaces 106, 107 may be Called the front end.

The chassis 102 may include a set of cooling fans 104, such as the four cooling fans 104 depicted in FIG. 1, for cooling the components of the computer system 100. In some cases, one or more cooling fans 104 will be positioned laterally on opposite sides of the power supply receiving spaces 106, 107.

The power supply unit 108 is aligned to be inserted into the upper power receiving space 107. When the power supply unit 108 is completely inserted into the upper power receiving space 107, the power supply unit 108 will contact the receiving connector on the upper power distribution board 166. Similarly, the power supply unit fully inserted into the lower power supply receiving space 106 will contact the receiving connector on the lower power distribution board under the upper power distribution board 166. During use, a fan (such as a fan in the power supply unit 108) can induce airflow to pass through the power supply unit 108 and pass through the upper power supply receiving space 107. This airflow can be guided to the airflow passage opening 110 and pass through the airflow passage 112. The air flow channel 112 may extend from the air flow channel opening 110 to the opposite end (for example, the front end) of the case through the length of the case 102.

For illustrative purposes, the wind deflector used to guide the air flow from the power supply receiving spaces 106, 107 to the air flow channel 112 is not depicted. Such a wind deflector will fit in the wind deflector space 114.

The air flow channel 112 can establish a separation between the first cabinet space 116 and the second cabinet space 118. As seen in Figure 1, the air flow channel 112 and the power supply receiving spaces 106 and 107 occupy most of the longitudinal length of the chassis 102. Therefore, in order to cross the chassis 102 laterally (for example, between the first chassis space 116 and the second chassis space 118 ), such a wire will pass through the windshield space 114. Therefore, the windshield disclosed herein may include wire passing channels to encourage one or more wires to cross the chassis 102 laterally.

Figure 2 is an isometric projection view of the wind deflector 222 according to some features of the present disclosure. The windshield 222 can be used in a computer system, such as the computer system 100 shown in FIG. 1. For example, the wind deflector 222 may be used in the wind deflector space 114 in FIG. 1.

The wind deflector 222 may include a baffle surface 230 to guide the air flow to the air flow space 228. In some cases, the airflow space 228 is defined by the first leg 286, the second leg 288, and the cross member 290 coupling the first leg 286 and the second leg 288 together. When installed, the receiving connector of the distribution board can be at least partially located in the airflow space 228.

The wire channel 226 may extend laterally across the wind deflector 222, for example from a first end (for example, the first end coincident with the first leg 286) to a second end (for example, with the second leg 288 overlap at the second end). The wire channel 226 is open on the top surface 224 of the wind deflector 222, although this is not necessarily the case. When the top surface 224 is open, the wire channel 226 can be closed by placing a cover (for example, a compressible air seal) on the top surface 224.

One or more ribs (for example, the four ribs 232 depicted in Figure 2) may extend from the baffle surface 230. Each rib 232 may have a power supply unit When inserted into the power supply receiving space, it faces the collision surface 292 of the power supply unit. When the power supply unit is inserted in an incorrect position, the connector of the power supply unit may contact the collision surface 292. The use of the ribs 232 extending from the baffle surface 230 can effectively stop the power supply unit from being inserted without using a large amount of material and by keeping the airflow passing through the wind deflector 222 efficiently. In some cases, the collision surface 292 is a flat plane, parallel to one end of the connector of the power supply unit (for example, perpendicular to the direction in which the power supply unit is inserted into the receiving space of the power supply).

FIG. 3 is a top view of the computer system 300 with the wind deflector 322 according to certain features of the present disclosure. The computer system 300 can be any suitable computer system, such as the computer system 100 in FIG. 1. The wind deflector 322 can be any suitable wind deflector, such as the wind deflector shown in FIG. 2.

The computer system 300 includes a case 302. The case 302 may include a first case space 316 and a second case space 318 divided by the air flow channel 312. For illustrative purposes, the chassis 302 may further include a power distribution group 320.

The first chassis space 316 may include a motherboard 334. The control card 336 (such as a redundant array of disks card or a host bus adapter card) may be coupled to the main board 334. The control card 336 may include a first connector 338, a second connector 340, and a third connector 342. Examples of suitable connectors include data connectors, such as serial advanced technology attachment connectors, serial attachment small computer system interface connectors, high-density serial advanced technology attachment connectors, high-density serial attachment small computer systems Interface connectors (for example, Mini-SAS HD SFF8643 connectors (Mini-SAS HD SFF8643 connectors)). Any number of connectors can be used.

The second chassis space 318 may include a set of storage drives 358 (e.g. For example, hard drives or solid state drives). As depicted in Figure 3, eight stacked three storage drives 358 are located in the second chassis space 318, for a total of twenty-four storage drives 358, although any number can be used. One or more drive boards 356 can be used to provide a set of storage drives 358 power and data connections.

The power distribution group 320 may include a lower power distribution board 368 located below the upper power distribution board 366 and a lower power supply receiving space located below the upper power supply receiving space 306. When in the correct position, the power supply unit fully inserted into the lower power supply receiving space or the upper power supply receiving space 306 can be coupled to the receiving connector on the lower power distribution board 368 or the upper power distribution board 366, respectively. Therefore, power can be distributed from the power supply unit to other electronic components of the computer system 300 via the power distribution boards 366 and 368. In some cases, one of the power distribution boards 366, 368 serves as a spare one of the other power distribution boards 366, 368.

During use, the air passing through the upper power supply receiving space 306 will be guided to the air flow channel 312 via the upper baffle 322. Similarly, the air passing through the receiving space of the lower power supply will be guided to the air flow channel 312 via the lower baffle.

To electrically couple the control card 336 to a set of storage drivers 358, several wires can be used. The first wire 346 is seen to couple the first connector 338 of the control card 336 with the connector 344 on the upper power distribution board 366. The first wire 346 is shown passing between the lower power distribution board 368 and the upper power distribution board 366, although this is not necessarily the case.

The second wire 348 can be seen to couple the second connector 340 with the connector 352 of the upper power board 366. The second wire passes through the wire passage of the upper baffle device 322.

The third wire, which is blocked by the upper power distribution board 366 from view, couples the third connector 342 with the connector of the lower power distribution board 368. The third wire passes through the lower baffle device The wire passes through the channel.

The upper power distribution board 366 and the lower power distribution board 368 may include one or more additional connectors (for example, connectors adjacent to the second chassis space 318) to connect the connectors 344, 352 and the lower power distribution board 368 The driver is electrically coupled to a set of storage drivers 358, for example via one or more driver boards 356.

FIG. 4 is a side cross-sectional view of the computer system 400 with two inserted lower power supply units 408 and upper power supply units 409 taken along the lines A to A of FIG. 3 according to some features of the present disclosure. The computer system 400 can be any suitable computer system, such as the computer system 300 in FIG. 3.

The case 402 of the computer system 400 may include an upper power supply receiving space 407 and a lower power supply receiving space 406. The upper power supply unit 409 and the lower power supply unit 408 can be respectively inserted into the upper power supply receiving space 407 and the lower power supply receiving space 406 in the insertion direction 482. The upper power supply unit 409 is completely inserted into the upper power supply receiving space 407 in an incorrect orientation. The lower power supply unit 408 is completely inserted into the lower power supply receiving space 406 in the correct position.

In the correct orientation, the connector 464 of the lower power supply unit 408 is inserted into (eg, receives and/or is operatively coupled to) the receiving connector 474 of the lower power distribution board 468. The lower wind deflector 422 is positioned above the receiving connector 474 of the lower power distribution board 468 at one end of the lower power supply receiving space 406. The rib 432 of the lower windshield 422 does not contact the body 462 of the lower power supply unit 408. The wire 450 is displayed in the wire passage 426 of the lower windshield 422. The wire 450 is depicted as having eight cores for illustrative purposes only; any suitable wire may be used for the wire 450. The compressible air seal 472 is positioned on the upper surface of the lower windshield 422 to help reduce, minimize or eliminate air leakage, thus promoting all air flow through the lower power supply receiving space 406, It is guided to the air passage 410 by the lower wind deflector 422. In some cases, the compressible air seal 472 may be sandwiched between the lower windshield 422 and the structural frame of the case, the lower power supply receiving space 406 and/or the upper power supply receiving space 407.

Since the lower power supply unit 408 is fully inserted in the correct position, the outer surface 477 of the lower power supply unit 408 is aligned with the chassis 402 and/or aligned with the lower power supply receiving space 406, as indicated by the line 476.
