Description

Technical Field

[0001] The utility model belongs to the technical field of equipment power supply waterproof structures, and in particular relates to a liquid cooling equipment power supply waterproof structure. Background Art

[0002] On switches, servers and other equipment, liquid cooling is more efficient and quieter than traditional air cooling, but there is also the risk of liquid leakage. Once leaked, it will bring major safety challenges to the product. In order to reduce the risk of liquid leakage, water pumps, cold plates, pipes, etc. are often designed with waterproof and leakage warnings. However, once a leak occurs, more or less liquid will enter the equipment, and key components of the equipment, such as power modules, lack protection measures when encountering leakage, and there is a risk of short circuit and burnout. Utility Model Content

[0003] The purpose of the utility model is to solve the disadvantage in the prior art that key components of products such as power modules lack protection measures when encountering liquid leakage, and to propose a liquid cooling equipment power supply waterproof structure.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A waterproof structure for a liquid cooling device power supply is designed, comprising a waterproof cover which is sleeved on the outside of a power module. The edge of the waterproof cover is sealed and connected to the top surface of a PCB board to form an upper waterproof structure of the power module.

[0006] It also includes a water-proof bulge with a closed-loop structure, which is stamped at the bottom of the casing and located below the power module. The top of the water-proof bulge is in contact with the bottom surface of the PCB board, so that the water-proof bulge forms a lower waterproof structure of the power module on the outside of the power terminal.

[0007] Furthermore, the waterproof cover is provided with a heat dissipation opening on one side of the heat dissipation brick of the power module.

[0008] Furthermore, a heat dissipation hole is provided at one end of the waterproof cover located at the power terminal.

[0009] Furthermore, a waterproof adhesive strip is provided between the waterproof cover and the PCB board.

[0010] Furthermore, the housing is provided with an anti-accidental-touch groove at the position of the power terminal, and the power terminal is located in the anti-accidental-touch groove.

[0011] The utility model proposes a waterproof structure for the power supply of a liquid cooling device, which has the beneficial effect that: the utility model can effectively prevent leakage from flowing into the power supply part, prevent short circuits from occurring, and improve the safety factor of key components of the equipment. At the same time, it can also prevent operators from accidentally touching the power supply terminals and avoid the risk of electric shock.

[0012] (1) The present invention adds a waterproof cover on the outside of the power module, which can effectively prevent liquid from flowing into the power supply part when a cold plate or water pipe leaks, thereby preventing a short circuit.

[0013] (2) The utility model provides a closed-loop water-isolating convex feature at the bottom of the housing to prevent leaking liquid from flowing into the convex bulge and short-circuiting the pins of the power terminal.

[0014] (3) The utility model can effectively prevent the operator from accidentally touching the power terminal and avoid the risk of electric shock by providing an anti-accidental touch groove on the waterproof cover. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The structural features of the present invention are now described in detail with reference to the accompanying drawings.

[0025] See also Figures 1-4 A waterproof structure for a liquid-cooled power supply includes a waterproof cover 4, which is mounted on the outside of a power module 3. The size of the waterproof cover 4 needs to be slightly larger than the external dimensions of the power module 3 so that it can completely cover the power module 3. To ensure that the heat dissipation of the power module 3 is not affected, a heat dissipation vent 42 is provided on the waterproof cover 4 at the heat dissipation brick 31 of the power module 3, so that the heat dissipation brick 31 is completely exposed to the outside. A heat dissipation hole 43 is provided on one end of the waterproof cover 4 at the power terminal 32. The arrangement of the heat dissipation vent 42 and the heat dissipation hole 43 ensures good heat dissipation of the power module 3. The edge of the waterproof cover 4 is sealed and connected to the top surface of the PCB board 2, forming an upper waterproof structure for the power module 3. To improve the sealing of the connection, a waterproof adhesive strip 5 is provided between the waterproof cover 4 and the PCB board 2. To this end, by adding the waterproof cover 2 to the outside of the power module 3, when liquid leaks, such as from a cold plate or water pipe, it can effectively prevent liquid from flowing into the power supply part and prevent short circuits.

[0026] It also includes a water-proof bulge 6 with a closed-loop structure. The water-proof bulge 6 is stamped at the bottom of the casing 1 to form an integrated structure with the casing 1. The water-proof bulge 6 is located below the power module 3. The top of the water-proof bulge 6 contacts the bottom surface of the PCB board 2, so that the water-proof bulge 6 forms a lower waterproof structure of the power module 3 on the outside of the power terminal 32. The setting of the water-proof bulge 6 can make the pin pins of the power terminal 32 located on the water-proof bulge 6 in an isolated state, which can block liquid leakage from the outside. To this end, the structural feature of the closed-loop water-proof bulge 6 is set at the bottom of the casing 1 to prevent liquid leakage from flowing into the bulge and short-circuiting the pin pins of the power terminal.

[0027] The housing 1 is provided with an anti-accidental touch slot 41 at the position of the power terminal 32, and the power terminal 32 is located in the anti-accidental touch slot 41. The provision of the anti-accidental touch slot 41 makes the power terminal 32 internal, which can effectively prevent the operator from accidentally touching the power terminal, avoiding the risk of electric shock, and improving the safety of the operator.

[0028] The utility model discloses a waterproof structure for the power supply of liquid cooling equipment, which has a simple structure. On the one hand, it can effectively prevent leakage from flowing into the power supply part and prevent short circuit. On the other hand, it can also prevent operators from accidentally touching the power supply terminal during use and avoid the risk of electric shock.
