Detailed Description
Generally, a heat exchange system of a power module (including but not limited to IGBT modules, battery cells, motors, chips and other heating components) is mostly composed of a heat pipe heat exchanger, the heat pipe heat exchanger is composed of an evaporation section and a condensation section, the heating end of the power module is fixedly installed on the evaporation section of the heat pipe heat exchanger through contact or embedding, and the condensation section dissipates heat into the atmosphere through an air cooling mode.
The heat exchange system of the current power module is composed of a plurality of independently operated heat pipe heat exchangers, so that the arrangement of the plurality of heat pipe heat exchangers is scattered, the whole size is large, and the miniaturization and centralized maintenance of the heat exchange system are not facilitated. And when the heat pipe heat exchangers are arranged in a concentrated way, hot air flowing through the condensation section of the heat pipe heat exchangers is easy to interfere with each other, so that the heat dissipation effect of the heat pipe heat exchangers is reduced.
Referring to fig. 1-15, in order to solve the problems of low integration level and poor heat dissipation effect of the heat exchange system of the conventional power module 411, the present application provides an integrated heat exchange device, which includes a frame 100, a first partition 200, a second partition 300 and a heat pipe heat exchanger 400, wherein the frame 100 is provided with a receiving cavity 110, and a top opening 111 and a bottom opening 112 respectively communicating with the receiving cavity 110.
The heat pipe heat exchanger 400 is disposed in the accommodating cavity 110, and the heat pipe heat exchanger 400 includes an evaporation section 410 and a condensation section 420 that are mutually communicated, the condensation section 420 is disposed at one end of the heat pipe heat exchanger 400 near the top opening 111, the evaporation section 410 is disposed at one end of the heat pipe heat exchanger 400 near the bottom opening 112, that is, the condensation section 420 is disposed above the evaporation section 410. That is, the heat pipe heat exchanger 400 of the present application belongs to a gravity heat pipe, the liquid working medium absorbs heat and gasifies in the evaporation section 410 and rises to enter the condensation section 420, then the gaseous working medium is liquefied by heat release in the condensation section 420, and the liquefied working medium flows back to the evaporation section 410 again under the action of gravity.
It should be noted that, the power module 411 is disposed in the evaporation section 410 of the heat pipe heat exchanger 400, specifically, one or more power modules 411 may be attached to a surface of the evaporation section 410, or may be partially immersed in the evaporation section 410 and welded with a shell of the evaporation section 410 in a sealing manner, or the power modules 411 may be completely immersed in a liquid working medium of the evaporation section 410. Specifically, in one embodiment, the power module 411 is adhered to the outer wall surface of the evaporation section 410 by a thermally conductive silicone grease.
It should be noted that, in the working state, the top height of the power module 411 is lower than the liquid level of the liquid working medium in the evaporation section 410.
Further, as shown in fig. 2, the condensing section 420 includes a condensing branch 421 and an outer fin 423, the condensing branches 421 are respectively connected to the evaporating section 410, and adjacent condensing branches 421 are arranged at intervals to form a condensing gap 422, the outer fin 423 is disposed in the condensing gap 422 and connected to an inner wall of the condensing gap 422, so that heat released after the gaseous operation in the condensing branch 421 is liquefied can be transferred to the outer fin 423 through an outer wall of the condensing branch 421, and finally, heat of the outer fin 423 is taken away by an external airflow, thereby realizing heat dissipation of the power module 411.
As shown in fig. 8 and 13, the plurality of heat pipe heat exchangers 400 enclose an airflow channel 120 that is formed to a plurality of parallel air channels and respectively communicates with the top opening 111 and the bottom opening 112, the airflow channel 120 includes a first air channel 121 and a second air channel 122, the first partition 200 is disposed in the first air channel 121, and the first partition 200 is located between the evaporation section 410 and the condensation section 420, and the second partition 300 is disposed at one end of the second air channel 122 near the top opening 111.
That is, the heat pipe heat exchanger 400 divides the accommodating chamber 110 into a plurality of air flow passages 120 arranged in parallel.
As shown in fig. 8 and 13, the first air passages 121 and the second air passages 122 are staggered, and the first air passages 121 can be communicated with the corresponding second air passages 122 through the condensation section 420, so that the top opening 111, the first air passages 121, the condensation section 420, the second air passages 122 and the bottom opening 112 can be sequentially communicated to form a heat exchange channel of external air flow.
It is understood that the first air passage 121 communicates with the second air passage 122 through the condensing gap 422 of the condensing section 420.
First, since the accommodating chamber 110 may be provided therein with a plurality of heat pipe heat exchangers 400 arranged in parallel, that is, a plurality of heat pipe heat exchangers 400 may be arranged in the accommodating chamber 110 in a concentrated manner, it is apparent that the integration level of the heat pipe heat exchangers 400 may be improved, thereby facilitating the miniaturization of the entire integrated heat exchange device.
Further, since the first partition board 200 is disposed in the first air passage 121 and the first partition board 200 is located between the evaporation section 410 and the condensation section 420, it is known that the first air passage 121 is separated by the first partition board 200, and the separating boundary is the junction of the evaporation section 410 and the condensation section 420. Also, because the second partition 300 is disposed on the second air passage 122, and the second partition 300 is disposed on an end of the second air passage 122 near the top opening 111, that is, the top end of the second air passage 122 is blocked by the second partition 300.
At this time, the external air flow enters from the top opening 111, and the external air flow directly enters the first air passage 121 from the top opening 111 due to the blocking effect of the second partition 300, and further, the external air flow cannot pass through the first air passage 121 because the first partition 200 is disposed in the middle of the first air passage 121, at this time, the external air flow changes the flow direction under the effect of the pressure difference, directly passes through the condensation section 420 of the side wall of the first air passage 121 and enters the adjacent second air passage 122, and the external air flow can leave the integrated heat exchange device from the second air passage 122 through the bottom opening 112.
In an embodiment, a rain shielding device (not shown) may be further provided above the top opening 111 to prevent rainwater from entering the top opening.
It should be noted that the external air flow does not enter the integrated heat exchanger from the bottom opening 112, so as to avoid the heat generated by the evaporation section 410 and the power module 411 from reducing the heat dissipation effect of the external air flow. From the above, the external air flow enters the integrated heat exchanger from the top opening 111 and leaves the integrated heat exchanger from the bottom opening 112, and the position of the external air flow entering the integrated heat exchanger and the position of the external air flow leaving the integrated heat exchanger are located in different orientations of the integrated heat exchanger, that is, the initial cold air (the external air flow at the air inlet end) and the hot air after heat exchange (the external air flow at the air outlet end) do not interfere with each other, so that the external air flow at the air inlet end is effectively ensured to always have a lower temperature, and the heat exchange effect of the integrated heat exchanger is ensured.
Further, since the first air passage 121 and the second air passage 122 are staggered, when the first air passage 121 is an air inlet end, the external air flow in the first air passage 121 can directly enter the second air passage 122. In this way, the condensation section 420 of each heat pipe heat exchanger 400 can be ensured to exchange heat with the external air flow of the initial air inlet directly, that is, the condensation section 420 of each heat pipe heat exchanger 400 does not need to exchange heat with the hot air discharged from the condensation sections 420 of other heat pipe heat exchangers 400, obviously, the heat dissipation effect of the condensation sections 420 of each heat pipe heat exchanger 400 can be greatly improved by the arrangement, and the heat dissipation uniformity of each heat pipe heat exchanger 400 can be ensured.
Further, by skillfully providing the first separator 200 and the second separator 300, the external air flow can be changed in time, so that the external air flow can directly penetrate the condensing section 420 along the horizontal direction, and the heat dissipation effect of the condensing section 420 can be optimized.
In an embodiment, as shown in fig. 1, the frame 100 is further provided with side openings 113, the side openings 113 are located between the top opening 111 and the bottom opening 112, and the plurality of side openings 113 are distributed along the circumference of the frame 100, and each side opening 113 is correspondingly provided with a heat pipe heat exchanger 400.
It should be noted that the condensation section 420 disposed at the side opening 113 may directly communicate with the external space through the side opening 113.
Therefore, the arrangement not only increases the distribution density of the heat pipe heat exchanger 400 in the integrated heat exchange device, but also increases the communication channels between the integrated heat exchange device and the external space on the basis of the bottom opening 112 and the top opening 111, thereby further improving the heat exchange efficiency of the integrated heat exchange device.
Specifically, in an embodiment, the heat pipe heat exchanger 400 is plugged at the side opening 113, that is, the side walls of the heat pipe heat exchanger 400 and the side opening 113 may be sealed and clamped, sealed and welded or sealed and adhered.
It should be noted that "blocked" means that the heat pipe heat exchanger 400 completely covers the corresponding side opening 113, so that the air flow can only flow through the side opening 113 from the condensation section 420 of the heat pipe heat exchanger 400.
By the arrangement, the external air flow for radiating the heat of the condensing section 420 can be ensured to pass through the condensing section 420 to enter and exit the side opening 113, so that the heat exchange efficiency of the integrated heat exchange device is ensured to the greatest extent.
Further, in an embodiment, as shown in fig. 5, 8, 10 and 13, the frame 100 is cubic, four side openings 113 are provided on the periphery of the frame 100, the heat pipe exchanger 400 disposed at the side openings 113 is defined as a side heat exchanger 430, the four side openings 113 are disposed in a quadrilateral shape, and the four side heat exchangers 430 disposed at the side openings 113 enclose a first cavity.
Four heat pipe heat exchangers 400 are arranged in the first cavity and are defined as first heat exchangers 440, two ends of each first heat exchanger 440 are respectively connected with adjacent side heat exchangers 430, an included angle between each first heat exchanger 440 and any side heat exchanger 430 connected with the first heat exchanger is an acute angle, and each first heat exchanger 440 is connected end to end and surrounds to form a second cavity.
Four heat pipe heat exchangers 400 are arranged in the second cavity and defined as second heat exchangers 450, two ends of each second heat exchanger 450 are respectively connected with adjacent first heat exchangers 440, an included angle between each second heat exchanger 450 and any one first heat exchanger 440 connected with the second heat exchanger 450 is an acute angle, and each second heat exchanger 450 is connected end to end and is enclosed to form and enclose a third cavity.
Defining the number of nested layers of the integrated heat exchange device as one when four first heat exchangers 440 are arranged in the first chamber; when four first heat exchangers 440 are arranged in the first cavity and four second heat exchangers 450 are arranged in the second cavity, the number of nesting layers of the integrated heat exchange device is two; the total nesting layer number n of the integrated heat exchange device is satisfied, and n is more than or equal to 1.
It should be noted that the frame 100 may be further provided with three side openings 113, five side openings 113, and other number of side openings 113, and the frame 100 may have other shapes such as a cylindrical shape, which are not listed herein.
Since the two ends of each first heat exchanger 440 are respectively connected to the adjacent side heat exchangers 430, the included angle between each first heat exchanger 440 and any side heat exchanger 430 connected thereto is an acute angle, and each first heat exchanger 440 is disposed end to end, so that the adjacent first heat exchangers 440 form a conical first flow guiding structure 441 at the inner wall of the same side heat exchanger 430.
Taking n equal to 2 as an example, when the external air flow enters the first chamber from the condensing section 420 of the side heat exchanger 430, firstly, the external air flow is spread over the entire first chamber under the guidance of the tapered first flow guiding structure 441, and secondly, the external air flow can pass through the first heat exchanger 440 and enter the second chamber, thereby completing the heat exchange of the condensing section 420 of the first heat exchanger 440.
Likewise, adjacent second heat exchangers 450 form a tapered second flow guide structure 451 at the inner wall of the same first heat exchanger 440, and the external air flow is distributed over the entire second chamber under the guidance of the tapered second flow guide structure 451, after which the external air flow can pass through the second heat exchanger 450 and enter the third chamber, thereby completing the heat exchange of the condensing section 420 of the second heat exchanger 450.
Therefore, similarly, when n is greater than or equal to 3, there are more diversion structures for diversion of the external air flow.
Moreover, it can be understood that the first flow guiding structure 441 and the second flow guiding structure 451 are not only used for guiding the external air flow entering from the side opening 113, but also the first flow guiding structure 441 and the second flow guiding structure 451 can play a better role in guiding the external air flow entering from the top opening 111 or the bottom opening 112.
Obviously, through the layer-by-layer arrangement of the multi-layer heat pipe heat exchanger 400, the distribution density of the heat pipe heat exchanger 400 in the integrated heat exchange device is greatly improved, and on the other hand, the external air flow can play a role in uniformly distributing when flowing layer by layer in the multi-layer nested heat pipe heat exchanger 400, so that the heat exchange uniformity of the integrated heat exchange device is improved.
In one embodiment, as shown in fig. 5, 8, 10 and 13, adjacent side heat exchangers 430 are vertically disposed, adjacent first heat exchangers 440 are vertically disposed, and adjacent second heat exchangers 450 are vertically disposed.
Further, in an embodiment, as shown in fig. 5, 8, 10 and 13, an included angle between each first heat exchanger 440 and the side heat exchanger 430 connected thereto is 45 degrees, and an included angle between each second heat exchanger 450 and the first heat exchanger 440 connected thereto is 45 degrees.
So arranged, the first and second flow guiding structures 441 and 451 have the most uniform flow guiding effect.
However, the four side heat exchangers 430 are not limited thereto, and may be arranged in a quadrangular structure other than rectangular shape, for example, in a parallelogram structure or a trapezoid structure, in other embodiments.
