The rotating portion 402 further includes a liquid collecting groove 406 for recovering leaked liquid, and the leaked liquid outlet 410 is correspondingly disposed on a side surface and/or a bottom surface of the liquid collecting groove 406, so that when leaked liquid exists in the fixing portion 401, the leaked liquid can flow to the liquid collecting groove 406 of the rotating portion 402 through the opening, and finally flows to the third pipe set 140 and/or the water pump module 100 through the leaked liquid outlet 410.
It is understood that the anti-leakage layer 400 is disposed on the second pipe set 130 in substantially the same manner as the anti-leakage layer 400 is disposed on the first pipe set 120, and the water pump module 100, the heat dissipation module 200, and the heat absorption module 300 may be connected to each other in a manner different from the above-mentioned manner, for example: a fourth pipe set (not shown) may be disposed between the heat dissipating module 200 and the heat absorbing module 300, and the anti-leakage layer 400 may be disposed on the fourth pipe set in the same manner, which is not limited in the disclosure.
Further, as shown in fig. 3, the opening formed on the fixing portion 401 can divide the fixing portion 401 into a first portion and a second portion, that is, the fixing portion 401 is completely interrupted at the opening. Preferably, the fixing portion 401 and the rotating portion 402 are rotatably connected by a bearing assembly 403, and the rotating portion 402 is connected to the first portion and the second portion and can rotate relative to the fixing portion 401, the water pump module 100, the heat sink module 200, and the heat sink module 300. Rotating portion 402 and stationary portion 401 may be tubular structures, and bearing assembly 403 may include rolling bearings, so that rotating portion 402 is rotatably sleeved on stationary portion 401 through bearing assembly 403. It is understood that the bearing assembly 403 may be replaced by other structures as long as the same effect can be achieved, and the present invention is not limited thereto.
In this embodiment, since the rotating portion 402 is rotatably connected to the fixing portion 401 by the bearing assembly 403, the side of the rotating portion 402 where the sump 406 is provided is always located below the first pipe set 120 or the second pipe set 130. Since the fixing portion 401 is completely interrupted at the opening, when the liquid collecting tank 406 is located under the first tube set 120 and/or the second tube set 130, the leaked liquid can be collected into the liquid collecting tank 406 smoothly.
Preferably, the rotating portion 402 further includes a weight 404, wherein the weight 404 is disposed on the same side as the sump 406 to ensure that the side of the rotating portion 402 where the sump 406 is disposed is maintained under gravity below the first tube set 120 and/or the second tube set 130. Specifically, the weight 404 may be fixedly attached to the ends of the slot of the sump 406 by bonding, welding, or the like. As shown in fig. 3, when the number of the weight blocks 404 is 2 or more than 2, the weight blocks 404 may be symmetrically disposed to ensure the stress balance. In addition, the weight block 404 may be made of a metal material such as stainless steel, or may be made of other materials, which is not limited in the present invention.
In one embodiment, the rotating portion 402 further includes a humidity sensor 405, the humidity sensor 405 being configured to collect humidity information in the sump 406, preferably disposed at the bottom of the sump 406 and coupled to the peristaltic pump 500. For example, when the humidity sensor 405 detects that the relative humidity in the sump 406 is greater than the threshold value set in the humidity sensor 405, the peristaltic pump 500 can be controlled to operate, and the operation of the peristaltic pump 500 can be controlled by the above-mentioned control method, so that unnecessary energy consumption of the peristaltic pump 500 can be avoided.
In one embodiment, the leakage-proof layer 400 may be made of rubber and/or plastic. Specifically, it may include at least one of polyvinyl chloride, polyethylene, and silicone.
Furthermore, the present invention also provides an electronic device 1, the electronic device 1 including: a housing 20, and the water cooling system 10 of any of the above embodiments, the water cooling system 10 being disposed in the housing 20. For example, the electronic device 1 may be a computer host, a projector, etc., where the electronic device 1 is taken as an example of a projector, a heat source in the projector is usually a module such as an optical engine and a CPU, etc., and the heat absorption module 300 in the water cooling system 10 may be correspondingly disposed on the module such as the optical engine and/or the CPU, etc.
In an embodiment, taking the electronic device 1 as a projector as an example, the projector will often hang the body upside down according to the projection requirement, because the rotating portion 402 is rotatably connected to the fixing portion 401 through the bearing assembly 403, and the weight block 404 is installed at the side where the liquid collecting tank 406 is installed, even if the projector is placed upside down, the end of the rotating portion 402 where the liquid collecting tank 406 and the weight block 404 are installed can be quickly restored to the original position, i.e. the liquid collecting tank 406 is always located below the first pipe set 120 or the second pipe set 130, so as to ensure that the leaked liquid can smoothly flow into the liquid collecting tank 406.
In summary, the water cooling system 10 and the electronic device 1 applying the same provided by the present invention can prevent the coolant in the first pipe set 120 and the second pipe set 130 from leaking to the electronic component through the anti-leakage layer 400. Meanwhile, a leakage liquid outlet 410 in the leakage-proof layer 400 is communicated with the third pipe set 140, and the leakage liquid is pumped to the water pump module 100 by the peristaltic pump 500 so as to be recycled by the water pump module 100. In addition, since the weight 404 is installed on the rotating portion 402, it can ensure that the liquid collecting tank 406 is always located below the first pipe set 120 and/or the second pipe set 130, so that the leaked liquid can smoothly flow into the liquid collecting tank 406, thereby improving the working efficiency of leaked liquid recovery in the water cooling system 10. The invention has simple structure and high leakage recovery efficiency, and ensures the reliability and safety of the water cooling system 10 and the electronic device 1 using the system.
