Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-4 The SVG star-mounted indoor water-cooled power module of this utility model includes a lower housing 1, an upper housing cover 2, and a power module assembly that is installed in conjunction with the lower housing 1 and the upper housing cover 2. A lower water-cooling heat dissipation assembly is fixed inside the lower housing 1 by screws, and an upper water-cooling heat dissipation assembly is fixed inside the upper housing cover 2 by screws. A hinge fixing assembly for disassembling and assembling the power module assembly is provided on one side of the lower housing 1. The upper and lower water-cooling heat dissipation assemblies facilitate all-round heat dissipation of the power module assembly. The lower water-cooling heat dissipation assembly includes a first water-cooling heat dissipation plate 8, which has a through-hole for heat dissipation of the bottom component of the power module assembly. The first water-cooled heat sink 8 has a main water outlet 10 and a secondary water inlet 13 on both sides to cooperate with water circulation. The front end of the first water-cooled heat sink 8 is provided with a rubber gasket 15 for cooperating with the main water outlet 10 and the secondary water inlet 13 to allow water to enter and exit. The rubber gasket 15 facilitates the leak prevention of the first water-cooled heat sink 8. The upper water-cooled heat sink assembly includes a second water-cooled heat sink 9. The second water-cooled heat sink 9 has a flow channel pipe that is opened through it to cooperate with the heat dissipation of the motherboard at the top of the power module assembly. The front end of the second water-cooled heat sink 9 is provided with a main water inlet 11 and a secondary water outlet 12 for cooperating with the flow channel pipe to enter and exit. The flow channel pipe facilitates the cooling of the top plate of the power module assembly by the second water-cooled heat sink 9.

[0020] In this invention, the lower and upper water-cooled heat dissipation components are connected by a connecting pipe 14 and dissipate heat through the circulation of internal coolant. A mounting cavity for sliding installation of the power module component is formed between the lower and upper water-cooled heat dissipation components. The connecting pipe 14 facilitates the circulation and cooling of the coolant between the lower and upper water-cooled heat dissipation components. The power module component includes a power module board 5 and two connection ports 7. A connecting line 6 for transmitting current is connected between the power module board 5 and the two connection ports 7. Two connection ports 7 are provided on the front end face of the lower housing 1 to connect with the connecting lines 6. The connection port is fixed to the connector with screws, which facilitates the connection between the connector port 7 and the power module board 5. The hinged fixing assembly includes a mounting plate 4 hinged to one side of the lower housing 1 and a limiting groove on one side of the upper housing cover 2. The mounting plate 4 is slidably provided with a sliding buckle 16 for fixing the mounting plate 4. The sliding buckle 16 is slidably engaged with the limiting groove. The engagement of the sliding buckle 16 and the limiting groove facilitates the hinged fixing of the mounting plate 4. Flange rings 17 for fixing with screws are provided on the outer sides of both the lower housing 1 and the upper housing cover 2. Multiple fixing feet 3 for fixing are provided on both sides of the lower end of the lower housing 1. The flange rings 17 facilitate the connection between the lower housing 1 and the upper housing cover 2.

[0021] Working principle: When this utility model is used, the coolant first enters the second water-cooled heat sink 9 through the main inlet 11 and flows in the inner channel pipe of the second water-cooled heat sink 9 to cool the top plate of the power module board 5. Then the coolant flows out through the secondary outlet 12. At the same time, under the action of the connecting pipe 14, it enters the inner channel of the first water-cooled heat sink 8 through the secondary inlet 13 to cool the bottom components of the power module board 5. Then the coolant flows out through the main outlet 10. If it is necessary to replace or repair the internal power module board 5, first disconnect the connection port 7 and disconnect the connecting wire 6. Then, by sliding the sliding buckle 16 and opening the mounting plate 4, the power module board 5 can be taken out from the inside of the equipment.
