As electronic devices continue to miniaturize, the space reserved for power modules is often very limited, and some systems are even closed. Therefore, heat dissipation has become a primary consideration. Improving power efficiency and reducing heat loss are crucial for the stable operation of power modules. Demand is increasing in areas such as railways, healthcare, and military, which involve issues such as public transportation and personal safety. The primary consideration is the module's reliability and operational safety. Power modules must continue to operate normally for long periods of time even in severe vibration or harsh environments, with no room for error. This presents a challenge to the technical development and production processes of domestic power module manufacturers.

[0025] Further, the motor 201 is fixedly connected with the positive and negative screw rod 210, and the positive and negative screw rod 210 is rotationally connected with the moving plate 207.

[0026] By adopting the above technical scheme, the motor 201 drives the positive and negative screw rod 210 to rotate, and the positive and negative screw rod 210 drives the moving plate 207 to move on the fixed block 209.

[0027] Further, the hose 205 is fixedly connected with the connecting pipe 206, and the hose 205 is stretchable.

[0028] By adopting the above technical scheme, the stretchability of the hose 205 enables the connecting pipe 206 to lengthen the hose 205 after moving, thereby avoiding damage to the hose 205.

[0029] Further, the DC power supply charging module body 1 is provided with a cold air mechanism 3, one side of the DC power supply charging module body 1 is fixedly connected with a connecting shell 301, an air inlet 302 is formed in the bottom of the connecting shell 301, a semiconductor refrigeration sheet 303 is fixedly connected in the connecting shell 301, and a docking port 304 is formed in one side of the connecting shell 301.

[0030] By adopting the above technical scheme, the cold air mechanism 3 further cools the air flowing in the connecting shell 301.

[0031] Further, a first dustproof net 4 is fixedly connected to one side in the DC power supply charging module body 1, and the first heat dissipation fan 202 and the first dustproof net 4 are located between the air collecting cover 203 and the docking port 304 of the connecting shell 301.

[0032] By adopting the above technical scheme, the first heat dissipation fan 202 can deliver the cold air in the connecting shell 301 to the air collecting cover 203, and the first dustproof net 4 prevents dust or sundries from entering the air collecting cover 203.

[0033] Further, a temperature sensor 5 is fixedly connected in the DC power supply charging module body 1, and a controller 6 is fixedly connected in the DC power supply charging module body 1.

[0034] By adopting the above technical scheme, the temperature sensor 5 monitors the DC power supply charging module body 1, and the controller 6 controls the start of the motor 201, the first heat dissipation fan 202, the semiconductor refrigeration sheet 303 and the second heat dissipation fan 9.

[0036] Furthermore, the circular hole 7 on the DC power charging module body 1 is connected to the cavity 8 on the DC power charging module body 1 , and the second dustproof net 10 is located on one side of the second heat dissipation fan 9 .

[0037] By adopting the above technical solution, cold air can flow into the cavity 8 on the DC power charging module main body 1 through the circular hole 7 on the DC power charging module main body 1, and then the cold air is discharged out of the DC power charging module main body 1 by the second cooling fan 9. The second dustproof net 10 prevents dust or debris from entering the cavity 8 on the DC power charging module main body 1 when the second cooling fan 9 is not working.

[0038] Working principle: When the temperature sensor 5 in the DC power charging module body 1 detects the set temperature, the temperature sensor 5 will transmit the signal to the controller 6, and the controller 6 will start the motor 201, the first cooling fan 202, the semiconductor cooling plate 303 and the second cooling fan 9. The first cooling fan 202 will transport the air in the connecting shell 301 to the wind collecting cover 203, so that the air in the connecting shell 301 begins to flow, and the outside air enters the connecting shell 301 from the air inlet 302 on the connecting shell 301. The flowing air will pass through the semiconductor cooling plate 303, and the semiconductor cooling plate 303 absorbs heat from the flowing air, so that the air flowing to the docking port 304 on the connecting shell 301 becomes further cooled. The cold air is transported to the wind collecting cover 203 by the first cooling fan 202, and the wind collecting cover 203 transports the cold air to the shunt pipe 204, and the shunt pipe 204 then cools the air through the hose 205 The cold air is transported to the connecting pipe 206, and finally the outlet pipe 208 on the connecting pipe 206 transports the cold air to the interior of the DC power charging module body 1. Then, the motor 201 drives the forward and reverse screw rods 210 to rotate, prompting the movable plate 207 to drive the connecting pipe 206 to move back and forth above the interior of the DC power charging module body 1, so that the cold air is evenly distributed inside the DC power charging module body 1, so that the contact surface of the DC power charging module body 1 can fully contact the cold air. Since the cold air flows from top to bottom, the cold air flows to the bottom of the interior of the DC power charging module body 1, and then flows from the circular hole 7 on the DC power charging module to the cavity 8 on the DC power charging module body 1. Finally, the second cooling fan 9 discharges the cold air out of the DC power charging module body 1, so that the air fluidity inside the DC power charging module body 1 is enhanced, so that the DC power charging module body 1 can quickly dissipate heat.
