Description

[0002] With the development of power supply technology, the power density of power supply modules has been greatly improved. The traditional heat dissipation adopts a structure of parallel and spaced heat dissipation fins. This structure is relatively simple. In order to ensure the heat dissipation area, a considerable volume needs to be ensured. However, the internal temperature of the power supply module is still relatively high, which reduces the reliability of the whole machine.

[0003] In order to improve the heat dissipation performance of the power supply, the existing technology usually adopts the way of adding a fan to improve the heat dissipation efficiency of the power supply. The fan blows cold air to the heat dissipation fins, and then increases the heat exchange efficiency between the air and the heat dissipation fins, so as to improve the heat dissipation performance. However, the passive heat dissipation structure with the added fan still cannot meet the heat dissipation demand of the power supply with large power, which reduces the reliability of the power supply.

[0039] The outer shell 2 is provided with a cooling box 3, the cooling box 3 is filled with cooling liquid, the outer shell 2 is provided with a sealed liquid cooling channel 21, the liquid cooling channel 21 is arranged around the outer shell 2, the liquid cooling channel 21 is provided with a partition plate 22, the cooling liquid enters the liquid cooling channel 21 from the first side of the partition plate 22, the cooling liquid in the liquid cooling channel 21 flows back to the cooling box 3 from the other side of the partition plate 22, the cooling box 3 is provided with a cooling pump 31 for supplying cooling liquid to the liquid cooling channel 21;

[0040] The liquid cooling channel 21 is provided with a heat dissipation fin 23, the heat dissipation fin 23 is provided with an air cooling channel 231 which is not communicated with the liquid cooling channel 21, the air cooling channel 231 penetrates through both ends of the outer shell 2, a fan is arranged at one end of the outer shell 2 to supply air to the air cooling channel 231, and the heat dissipation fin 23 is arranged along the length direction of the outer shell 2.

[0041] Compared with the air cooling method in the prior art, by arranging the liquid cooling channel 21 and the heat dissipation fin 23, the cooling liquid has a larger contact area with the heat dissipation channel and the outer shell 2, and the heat dissipation fin 23 is immersed in the cooling liquid, so that the cooling liquid has a larger heat exchange area with the heat dissipation fin 23, thereby improving the heat dissipation efficiency of the outer shell 2.

[0042] The air flow and the heat dissipation fin 23 are not uniform in contact due to the shape and machining precision of the heat dissipation fin 23 in the prior art, therefore, the air cooling method cannot effectively meet the heat dissipation demand of the power supply.

[0049] The air holes 261 have a larger cross-sectional area, so that the heat dissipation fins 23 and the airflow in the air cooling channel 231 have a larger heat exchange area, thereby improving the air cooling efficiency.

[0050] The cooling liquid in the liquid cooling channel 21 can make the temperature of the liquid cooling channel 21 uniform, so that the power supply is not prone to local overheating. At the same time, the heat dissipation fins 23 are immersed in the cooling liquid, and the temperature of each part of the heat dissipation fins 23 is uniform, so that the heat dissipation fins 23 can better dissipate heat and prevent the power supply from being too high in temperature.

[0055] Mode two: refrigeration piece 5 works, cooling pump 31 and fan do not work, at this time, the air flow is naturally entered into the air channel and exchanges heat with the heat dissipation fin 23, at the same time, the temperature of the cooling liquid in the cooling box 3 is reduced, so that the cooling liquid in the cooling box 3 exchanges heat with the cooling liquid in the liquid cooling channel 21, so as to dissipate heat for the power supply.

[0056] Mode three: fan works, refrigeration piece 5 and cooling pump 31 do not work, the fan performs air cooling through the air cooling channel 231, at the same time, the cooling liquid in the liquid cooling channel 21 exchanges heat with the cooling liquid in the cooling liquid.

[0057] Mode four: fan and refrigeration piece 5 work at the same time, cooling pump 31 does not work, the fan performs air cooling at the same time, the cooling liquid in the cooling box 3 has a lower temperature, the heat exchange efficiency between the cooling liquid in the cooling box 3 and the cooling liquid in the liquid cooling channel 21 is improved, and the heat dissipation efficiency is improved.

[0058] Mode five: fan, refrigeration piece 5 and cooling pump 31 work at the same time, air cooling and liquid cooling are used to dissipate heat at the same time.

[0059] Mode six: fan and cooling pump 31 work, refrigeration piece 5 does not work.

[0060] Mode seven: refrigeration piece 5 and cooling pump 31 work, fan does not work.

[0062] The switching between different modes is only to control the working or stopping of the fan, cooling pump 31 and refrigeration piece 5, and the controller for realizing the function is a common control unit in the prior art. The higher the heat dissipation efficiency requirement is, the more devices participate in heat dissipation. The devices participating in heat dissipation refer to one or more of the cooling pump 31, the fan and the refrigeration piece 5.

The box body 35 and the shell 2 are in an integrated structure, and heat exchange can also be performed between the box body 35 and the shell 2 to further improve the heat dissipation efficiency of the power supply.
