Description

Technical Field:

[0001] The utility model relates to a heat dissipation system for a high-power PCB board of a washing machine and the washing machine, belonging to the technical field of washing machines. Background Art:

[0002] With the increase in the washing capacity and functions of the washing machine, the power of the PCB board increases. Therefore, in order to improve the heat dissipation effect of the high-power PCB board, the prior art realizes it by means of air cooling with a large-size heat dissipation module (commonly an aluminum sheet). This method has a large size of the heat dissipation module and low heat dissipation efficiency, resulting in a relatively large size of the PCB board, which is not conducive to the space arrangement inside the washing machine. Moreover, the existing heat dissipation module is fixed on the PCB board with screws, and the operation efficiency is low.

[0003] Therefore, it is necessary to improve the prior art to solve the deficiencies of the prior art. Summary of the Utility Model:

[0004] The utility model provides a heat dissipation system for a high-power PCB board of a washing machine and the washing machine to solve the above problems existing in the prior art. By arranging a circulating water path in the heat dissipation system, the size of the heat dissipation module can be greatly reduced, and the heat dissipation effect of the high-power PCB board can be improved.

[0005] The utility model adopts the following technical scheme: A heat dissipation system for a high-power PCB board of a washing machine includes a heat dissipation module, a water tank and a circulation pump. The heat dissipation module includes a plurality of spaced-apart heat dissipation fins and a bent heat dissipation pipe passing through the plurality of heat dissipation fins. Two rubber hoses are connected to the water tank. One of the two rubber hoses is an outlet pipe connected to one end of the heat dissipation pipe, and the other is a water suction pipe connected to the inlet end of the circulation pump. The other end of the heat dissipation pipe is connected to an inlet pipe, and the other end of the inlet pipe is connected to the outlet end of the circulation pump.

[0006] Further, the heat dissipation pipe is a copper pipe.

[0007] Further, the heat dissipation pipe is an aluminum pipe.

[0008] Further, the heat dissipation fins are welded to the PCB board.

[0009] Further, the size of the heat dissipation module is 80mm * 40mm * 40mm.

[0010] Further, the thickness of a single heat dissipation fin is 0.6mm.

[0011] The utility model also adopts the following technical scheme: A washing machine includes the aforementioned heat dissipation system for a high-power PCB board of a washing machine.

[0012] The utility model has the following beneficial effects: The heat dissipation system of the utility model for the high-power PCB board of the washing machine arranges a circulating water path of copper pipes or aluminum pipes in the heat dissipation module, which can greatly improve the heat dissipation effect of the high-power PCB board, and the PCB board does not need to consider the heat dissipation space for air flow, further reducing the volume of the heat dissipation module. Description of the drawings:

[0013] Figure 1 It is a schematic diagram of the heat dissipation system of the utility model for the high-power PCB board of the washing machine. Specific implementation manners:

[0014] The following further describes the utility model with reference to the drawings.

[0015] The heat dissipation system of the utility model for the high-power PCB board of the washing machine includes a heat dissipation module 1, a water tank 2 and a circulation pump 3. The heat dissipation module 1 includes a plurality of spaced-apart heat dissipation fins 10 and a bent heat dissipation pipe 11 passing through the plurality of heat dissipation fins 10. The heat dissipation fins 10 are welded to the PCB board 4. Two rubber hoses are connected to the water tank 2. One of the two rubber hoses is a water outlet pipe 20 connected to one end of the heat dissipation pipe 11, and the other is a water suction pipe 21 connected to the inlet end of the circulation pump 3. The other end of the heat dissipation pipe 11 is connected to a water inlet pipe 5, and the other end of the water inlet pipe 5 is connected to the outlet end of the circulation pump 3. The heat dissipation pipe 11 is a copper pipe or an aluminum pipe.

[0016] In the utility model, the size of the heat dissipation module 1 is 80mm * 40mm * 40mm, and the thickness of a single heat dissipation fin 10 is 0.6mm.

[0017] The working principle of the heat dissipation system of the utility model for the high-power PCB board of the washing machine is as follows: A circulating water path of copper pipes or aluminum pipes is arranged in the heat dissipation module 1, and through the circulation pump and the water tank, the recycling of cooling water is realized, thereby improving the heat dissipation effect of the high-power PCB board. At the same time, the size of the heat dissipation module in the heat dissipation system of the utility model is small, thereby reducing the size of the entire PCB board, which is beneficial to the space arrangement inside the washing machine.

[0018] The above are only the preferred implementation manners of the utility model. It should be noted that for those of ordinary skill in the art, several improvements can be made without departing from the principle of the utility model, and these improvements should also be regarded as the protection scope of the utility model.
