[0021] The present utility model will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0022] Refer to Figures 1 to 5As shown in the figure, the utility model provides a technical solution: on one side of the power module housing 1, there is an electric energy input port 2 installed. On the other side of the power module housing 1, there is an electric energy output wire 3 installed. On one side of the power module housing 1, there is a heat sink 4 fixedly connected. Both the power module housing 1 and the heat sink 4 are made of heat-conducting materials. The facing surfaces of the heat sink 4 and the radiator fan 5 are connected by gluing. On the top and bottom of the heat sink 4, there are through grooves 15 opened. On both sides inside the through grooves 15, there are connecting rods 9 fixedly connected. On the top and bottom of the radiator fan 5, there are first sliding grooves 7 opened. Inside the first sliding grooves 7, there are two L-shaped sliding rods 8 slidably connected. Inside the L-shaped sliding rods 8, there are thrust springs 10 fixedly connected. One side of the heat sink 4 is in contact with the silica gel 6. At the bottom of the first sliding groove 7, there is a limit sliding groove 11 opened. At the bottom of the L-shaped sliding rod 8, there is a limit slider 12 fixedly connected. Inside the limit slider 12, there is a storage groove 13 opened. Inside the storage groove 13, there is a pulley 14 installed. Both the power module housing 1 and the heat sink 4 are made of heat-conducting materials. By installing the heat sink 4 on one side of the power module housing 1, the heat of the power module housing 1 can be conducted to the heat sink 4, and the heat can be quickly lost through the heat sink 4 to cool down the power module housing 1 and prevent the equipment from being damaged due to the high temperature of the power module housing 1. When the user connects the power module housing 1 to the electrical appliance, some electrical appliances have a large power, which makes the temperature of the power module housing 1 relatively high. When the heat dissipation efficiency of the heat sink 4 is lower than the heating speed of the power module housing 1, the radiator fan 5 can quickly dissipate the heat of the heat sink 4, so that the temperature of the heat sink 4 is always lower than the temperature of the power module housing 1, and the heat of the power module housing 1 can be continuously conducted to the heat sink 4 to improve the heat dissipation efficiency. When the user installs the radiator fan 5, silica gel 6 is applied to the contact surface between the radiator fan 5 and the heat sink 4, which can prevent a gap between the heat sink 4 and the radiator fan 5, resulting in slow heat conduction and affecting the heat dissipation efficiency. At the same time, the silica gel 6 has good heat conductivity and will not affect the heat sink 4 from conducting heat to the radiator fan 5. When the user needs to install the radiator fan 5, align the radiator fan 5 with the groove of the heat sink 4 and insert it. Move the L-shaped sliding rods 8 to both sides to limit the radiator fan 5 so that the radiator fan 5 is fixed to one side of the heat sink 4. By disassembling and assembling the radiator fan 5, the power module housing 1 can be adapted to different electrical appliances. Press the L-shaped sliding rods 8 towards the middle, align the radiator fan 5 with the groove position of the heat sink 4 and insert it. Release the L-shaped sliding rods 8. Under the thrust of the thrust springs 10, the L-shaped sliding rods 8 are pushed to move to both sides to limit the radiator fan 5. At the same time, the thrust of the thrust springs 10 can prevent the L-shaped sliding rods 8 from moving towards the middle due to vibration, resulting in the detachment of the radiator fan 5. During the process of moving the L-shaped sliding rods 8, the limit sliders 12 at the bottom of the L-shaped sliding rods 8 move inside the limit sliding grooves 11 to assist the movement of the L-shaped sliding rods 8 and prevent the L-shaped sliding rods 8 from tilting during the movement, resulting in stuck movement.

[0023] Working principle: By installing a heat sink 4 on one side of the power module housing 1, the heat of the power module housing 1 can be conducted to the heat sink 4, and the heat can be quickly dissipated through the heat sink 4 to cool the power module housing 1 and prevent equipment damage caused by the high temperature of the power module housing 1. When the power module housing 1 is connected to an electrical appliance, some electrical appliances have a large power, which makes the temperature of the power module housing 1 relatively high. When the heat dissipation efficiency of the heat sink 4 is lower than the heating speed of the power module housing 1, the heat of the heat sink 4 can be quickly dissipated through the cooling fan 5, so that the temperature of the heat sink 4 is always lower than the temperature of the power module housing 1, and the heat of the power module housing 1 can be continuously conducted to the heat sink 4. When installing the cooling fan 5, silicone 6 is applied to the contact surface between the cooling fan 5 and the heat sink 4, which can prevent gaps between the heat sink 4 and the cooling fan 5, resulting in slow heat conduction and affecting the heat dissipation efficiency. At the same time, silicone 6 has good thermal conductivity and will not affect the heat conduction from the heat sink 4 to the cooling fan 5. When installing the cooling fan 5, align the cooling fan 5 with the groove of the heat sink 4 and insert it. Move the L-shaped slide rod 8 to both sides to limit the cooling fan 5 and fix the cooling fan 5 to one side of the heat sink 4. When installing the cooling fan 5, press the L-shaped slide rod 8 towards the middle, align the cooling fan 5 with the groove position of the heat sink 4 and insert it. Release the L-shaped slide rod 8, and under the thrust of the thrust spring 10, the L-shaped slide rod 8 is pushed to move to both sides to limit the cooling fan 5. At the same time, the thrust of the thrust spring 10 can prevent the L-shaped slide rod 8 from moving towards the middle due to vibration, resulting in the detachment of the cooling fan 5. During the movement of the L-shaped slide rod 8, the limit slider 12 at the bottom of the L-shaped slide rod 8 moves inside the limit chute 11 to assist the movement of the L-shaped slide rod 8 and prevent the L-shaped slide rod 8 from tilting during movement. During the movement of the L-shaped slide rod 8, the pulley 14 at the bottom of the limit slider 12 rotates inside the storage groove 13, reducing the friction between the bottom of the limit slider 12 and the bottom inside the limit chute 11, making the movement of the L-shaped slide rod 8 smoother and preventing wear of the bottom of the limit slider 12 after long-term use.
