Detailed Description
In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the invention, whereby the invention is not limited to the specific embodiments disclosed below.
Referring to fig. 1 to 4, a liquid cooling pipeline 100 according to an embodiment of the present application includes: a pipeline body 10, an on-off assembly 20 and a impurity collecting container 30. The pipe body 10 is used for circulating a cooling fluid (such as cold water, cold oil, etc. and low-temperature fluid medium), and for example, the pipe body 10 may be a round pipe, a square pipe, etc. It should be noted that the structure shown in fig. 1 is only a section of the liquid cooling pipe 100 in actual use. According to practical needs, one group, two groups or more groups of on-off assemblies 20 and impurity collecting containers 30 can be installed on the single pipeline body 10, but when two groups or more are adopted, the multistage filtering effect on cooling liquid can be formed.
The inner wall of the pipeline body 10 is provided with a trash outlet 11; the on-off assembly 20 is connected to the impurity discharging port 11, and the on-off assembly 20 has a communication state and an off state; the impurity collecting container 30 is connected to the on-off assembly 20; when the on-off assembly 20 is in a communicating state, the on-off assembly 20 can connect the impurity discharging port 11 with the impurity collecting container 30, so that impurities in the cooling liquid in the pipeline body 10 fall into the impurity collecting container 30 through the on-off assembly 20 under the action of gravity.
In summary, implementing the technical scheme of the embodiment has the following beneficial effects: the liquid cooling pipeline 100 of the scheme is applied to the liquid cooling unit, and when the liquid cooling unit works, the on-off assembly 20 is in an off state, and the cooling liquid flows in the liquid cooling pipeline 100 so as to cool the battery pack or the battery module. Because impurity such as metal chip is mingled with in the coolant liquid that flows in the pipeline body 10, switch to the intercommunication state through operation break-make subassembly 20 for break-make subassembly 20 can be with the trash discharging port 11 of pipeline body 10 and collection miscellaneous container 30 intercommunication, when the metal chip in the coolant liquid flows trash discharging port 11 department, can drop from trash discharging port 11 under the dead weight effect, and then fall into collection miscellaneous container 30, realize the clean processing of filtration to the coolant liquid from this, in order to avoid the metal chip to constantly flow into and pile up in the filter core of liquid cooling unit, cause the filter core to block up, influence the refrigeration heating effect of liquid cooling unit, prevent the coil overload of liquid cooling unit and burn out, improve the life of liquid cooling unit.
In general, the particles of metal chips entrained in the coolant are present in a fraction of the size. The metal scraps with larger particles have larger self weight, and when the metal scraps flow to the impurity discharging port 11 along with the cooling liquid, the metal scraps can directly fall out of the impurity discharging port 11 and fall into the impurity collecting container 30 under the action of dead weight. But the metal scraps with smaller particles are difficult to fall into the impurity discharging port 11 under the action of dead weight due to the small weight of the metal scraps and the driving action of flowing cooling liquid, but pass through the impurity discharging port 11 along with the cooling liquid, and finally flow into the filter element of the liquid cooling unit to cause the blockage problem.
In view of the above, in some embodiments, the liquid cooling pipeline 100 further includes a baffle 40, where the baffle 40 is disposed on the inner wall of the pipeline body 10, and the baffle 40 is disposed near the downstream edge of the impurity discharging port 11 in the flowing direction of the cooling liquid.
That is, it can be understood that, the baffle 40 is located in the flow path of the small-sized and light metal chips in the lower-layer liquid flow of the cooling liquid, and even if the metal chips are carried by the cooling liquid to pass over the impurity discharging opening 11, the baffle 40 can form a blocking effect on the small-sized and light metal chips, the metal chips are stacked on the side surface of the baffle 40 facing the impurity discharging opening 11, and after a certain amount of metal chips are stacked, the metal chips can fall into the impurity discharging opening 11 by themselves, that is, the effect of blocking the small-sized and light metal chips into the impurity collecting container 30 is achieved. On the other hand, if the baffle 40 is disposed at the upstream edge of the impurity discharging port 11 in the flowing direction of the coolant, the small-sized and light-weight metal chips are blocked by the baffle 40 at the position where the baffle 40 contacts the inner wall of the pipe body 10 before passing over the impurity discharging port 11, so that the metal chips are not easily discharged from the impurity discharging port 11, and the problem of clogging caused by the metal chips flowing into the filter element of the liquid cooling unit is fundamentally prevented.
In other embodiments, a blocking net may be disposed near the downstream edge of the impurity discharging port 11 in the flowing direction of the coolant, and the size of the mesh of the blocking net is preferably set to allow the coolant to pass through, but the blocking effect of blocking the metal chips or particles by the blocking plate 40 is more remarkable, and the edge of the blocking net is connected to the inner wall of the pipe body 10.
In some embodiments, the on-off assembly 20 includes a communication pipe 21 and an on-off valve, a first pipe end of the communication pipe 21 is connected to the impurity discharging port 11, a second pipe end of the communication pipe 21 is connected to the impurity collecting receptacle 30, the on-off valve is movably disposed on the communication pipe 21, and the on-off valve is capable of switching on or off the first pipe end and the second pipe end of the communication pipe 21. The on-off valve is arranged on the communicating pipe 21, the communicating pipe 21 plays a role in loading and fixing the on-off valve, so that the communicating state of the on-off assembly 20 is conveniently switched, the cooling liquid is conveniently and regularly cleaned and filtered, and meanwhile, the cooling liquid is not influenced to normally participate in the operation of the liquid cooling unit.
With continued reference to fig. 2 and 4, in particular, the communication pipe 21 of the present embodiment is installed vertically below the pipe body 10. The on-off valve comprises a valve seat 22, a valve rod 23 and a valve core 24, wherein the valve seat 22 is arranged on the communicating pipe 21, the valve rod 23 is rotatably arranged on the valve seat 22, and the valve core 24 is arranged at one end of the valve rod 23 and positioned in the communicating pipe 21. The valve seat 22 is also a pipe with two ends penetrating through, so that the valve rod 23 can be inserted into the valve seat 22 and one end of the valve rod extends into the communicating pipe 21, so that the valve core 24 is installed and positioned in the communicating pipe 21. Further, the other end of the valve stem 23 protrudes outside the valve seat 22 to facilitate the rotation operation by the worker.
Further, the valve core 24 is provided with a through hole 241, and in the communicating state, the valve rod 23 is in the first rotating position, and the through hole 241 is communicated with the pipe cavity of the communicating pipe 21; in the off state, the valve stem 23 is in the second rotational position, and the through hole 241 is blocked by the inner pipe wall of the communication pipe 21. The on-off valve has simple structure composition, is convenient to operate and switch the on-off state and the on-off state of the on-off valve, and improves the working reliability of the on-off valve. It will be appreciated that the on-off valve may be a ball valve.
It is easy to understand that the maximum diameter of the valve core 24 should be similar to the inner pipe diameter of the communicating pipe 21, so as to ensure that the outer wall of the valve core 24 is in close contact with the inner pipe wall of the communicating pipe 21 to form sealing fit in the off state of the on-off valve, and prevent the leakage of the cooling liquid.
The diameter of the through hole 241 on the valve core 24 is smaller than the inner pipe diameter of the communicating pipe 21, when the valve core 24 is at the maximum opening position, that is, the hole center line of the through hole 241 coincides with the pipe center line of the communicating pipe 21, the edge part of the valve core 24 and the closing of the communicating pipe 21 form a concave space, and the concave space easily hides metal scraps, so that the problem of blockage is easily caused.
With reference to fig. 2, in some embodiments, the inner tube wall of the communication tube 21 is provided with a guiding portion 211, and the guiding portion 211 is disposed between the impurity discharging port 11 and the valve core 24. The guide portion 211 guides the swarf dropped from the trash port 11 directly into the through hole 241, so that the swarf can be prevented from accumulating at the spool 24.
Specifically, in some embodiments, the guide portion 211 is formed in a tapered cylindrical shape, the large diameter end of the guide portion 211 is opposite to the impurity discharging port 11, the small diameter end of the guide portion 211 is opposite to the through hole 241 in the communicating state of the on-off assembly 20, and the diameter of the small diameter end of the guide portion 211 is not larger than the diameter of the through hole 241. A better guiding and moving effect is formed on the metal scraps, and all the metal scraps can be ensured to smoothly pass through the valve core 24.

The impurity collecting container 30 is connected with the communicating pipe 21 in a simple way, is convenient to assemble and disassemble, and is convenient to take down the impurity collecting container 30 regularly to intensively clean the collected impurities such as metal scraps.
For example, in the present embodiment, the first connection portion 311 is provided with a first thread, and the second connection portion 212 is provided with a second thread, and the second thread is in threaded engagement with the first thread; the outer wall of the impurity collecting receptacle 30 is provided with a holding portion 32 for facilitating screwing of the impurity collecting receptacle 30.
