Thus, unless otherwise indicated, the illustrated combinations are not intended to be limiting.
The principles of the present utility model are described in detail below with reference to the drawings and examples.
The utility model provides a liquid cooling heat dissipation structure of a power supply, which is shown in fig. 1-6, and comprises a box body 1 (a top cover is not shown) with an inner cavity, a circuit board 2 is arranged in the inner cavity, two heat exchange plates 3 are vertically arranged on the circuit board 2 at intervals, a refrigerant flow channel 31 with a Tesla valve characteristic is distributed in the heat exchange plates 3, and heat exchange fins 32 are distributed on two side surfaces of the heat exchange plates 3.

The flow rate of the refrigerant in the heat exchange plate 3 can be increased by the tesla valve-shaped refrigerant flow passage 31, and heat exchange can be accelerated. In addition, the heat exchange fins 32 can enlarge the effective heat exchange area of the heat exchange plate 3. The liquid inlet 33 and the liquid outlet 34 of the refrigerant flow channel 31 are positioned on the side surface of the heat exchange plate 3 and extend out of the box body 1 to be connected with an external refrigerant pipeline.
In this embodiment, the liquid cooling structure of the power supply further includes a radiator 4 that can be mounted on the top of the heat generating device, and one side of the radiator 4 is detachably mounted on the side surface of the heat exchange plate 3. The heat sink 4 may help surface-insulated, bulky heat-generating devices 6 to dissipate heat, such as high voltage filter capacitors, inductors with insulating housings on top, switching tubes, and schottky tubes. For the heat generating devices 6 without insulating housing on the top, the heat sink 4 can also be adjusted to a position above the heat generating devices 6 with a short distance for heat exchange.
