[0029] The method for maintaining constant temperature and heat dissipation of a power exchange cabinet by using the above-mentioned device for maintaining constant temperature and heat dissipation of a power exchange cabinet comprises the following steps:

[0030] S1. The temperature sensor measures the temperature to detect whether the temperature inside the power exchange cabinet exceeds 25°C, and transmits the temperature detection data to the PLC control mainboard. If the temperature is lower than 25°C, the temperature is kept constant; if the temperature is higher than 25°C, the next step is carried out;

[0032] S3, the fan is used to dissipate heat and cool down. When the temperature detected by the temperature sensor is higher than 35℃, the water cooling component is turned on. The water pump draws cold water from the water tank and transports it to the heat exchange pipe in the power exchange cabinet through the conduit. The heat is cooled through the heat exchange pipe. The water in the heat exchange pipe takes away the heat in the power exchange cabinet. When the temperature detected by the temperature sensor drops to 25℃, the fan and water pump are turned off to maintain a constant temperature. When the temperature continues to be higher than 45℃, proceed to the next step.

[0033] S4. The fan performs air cooling and the water cooling component performs water cooling. When the temperature of the power swap cabinet is still higher than 45°C, the semiconductor refrigeration plate in the power swap cabinet performs cooling to rapidly reduce the temperature inside the power swap cabinet. When the temperature sensor detects that the temperature is lower than 25°C, the fan, water cooling component and semiconductor refrigeration plate are turned off to maintain a constant temperature inside the power swap cabinet.

[0034] In the present invention, the water cooling heat dissipation component includes a water tank, a water pump and a heat exchange tube. The heat exchange tube is located inside the power exchange cabinet, the water tank is located outside the power exchange cabinet, and a water pump is provided at the upper end of the water tank.

[0035] By adopting the above technical solution, the water pump draws cold water from the water tank and transports it into the heat exchange pipes in the power exchange cabinet through the conduit. The heat is cooled by the heat exchange pipes, and the water in the heat exchange pipes carries away the heat in the power exchange cabinet.

[0036] In the present invention, a plurality of heat dissipation fins are provided on the side of the water tank, and a heat insulation pad is provided between the water tank and the power exchange cabinet.

[0037] By adopting the above technical solution, the water in the water tank can dissipate heat, avoiding poor heat exchange effect and affecting the heat dissipation efficiency.

[0038] In the present invention, fans are arranged around the power exchange cabinet, and dustproof nets are arranged at positions corresponding to the power exchange cabinet and the fans.

[0039] By adopting the above technical solution, air cooling is facilitated and dust is prevented from entering the power exchange cabinet.

[0040] Furthermore, in the present invention, when the temperature inside the power exchange cabinet is lower than 25°C, the semiconductor refrigeration plate reversely supplies power to heat the interior.

[0041] By adopting the above technical solution, the constant temperature operation of the battery exchange cabinet can be achieved to avoid the impact of low temperature on the use effect.

[0042] In the present invention, the heating end of the semiconductor refrigeration plate is further provided with a plurality of heat dissipation fins.

[0043] By adopting the above technical solution, the heat dissipation effect of the heating end of the semiconductor refrigeration plate is improved, making it convenient for long-term use.

[0044] Furthermore, in the present invention, when the temperature in the power exchange cabinet is higher than 25°C and lower than 35°C, the fan starts, when the temperature in the power exchange cabinet is higher than 35°C and lower than 45°C, the water cooling component starts, and when the temperature in the power exchange cabinet is higher than 45°C, the semiconductor refrigeration sheet works.

[0045] By adopting the above technical solution, it is ensured that the temperature inside the battery swap cabinet can be reduced in a timely and effective manner under various circumstances.

[0046] In the present invention, the temperature sensor, the semiconductor cooling sheet, and the water pump fan are all electrically connected to the PLC control mainboard.

[0047] By adopting the above technical solution, the components in the battery swap cabinet can be guaranteed to work stably and maintain a constant temperature.

[0048] The working principle and use process of the present invention: When the present invention is used, the temperature sensor measures the temperature to detect whether the temperature in the power exchange cabinet exceeds 25°C, and transmits the temperature detection data to the PLC control mainboard. If the temperature is lower than 25°C, the temperature is kept constant. If the temperature is higher than 25°C, the fan is turned on, and the PWM algorithm speed regulation system controls the fan speed and adjusts the air volume to bring out the charging heat. When the temperature detected by the temperature sensor drops to 25°C, the fan is turned off to maintain a constant temperature. The fan dissipates heat and cools down. When the temperature detected by the temperature sensor is higher than 35°C, the water cooling component is turned on, and the water pump pumps cold water out of the water tank. The heat is sucked and transported into the heat exchange tubes in the power swap cabinet through the ducts. The heat is cooled by the heat exchange tubes. The water in the heat exchange tubes takes away the heat in the power swap cabinet. When the temperature sensor detects that the temperature drops to 25°C, the fan and the water pump are turned off to maintain a constant temperature. When the temperature continues to be higher than 45°C, the fan performs air cooling and the water cooling component performs water cooling. When the temperature of the power swap cabinet is still higher than 45°C, the semiconductor refrigeration sheet in the power swap cabinet is cooled to quickly reduce the temperature in the power swap cabinet. When the temperature sensor detects that the temperature is lower than 25°C, the fan, water cooling component and semiconductor refrigeration sheet are turned off to maintain a constant temperature in the power swap cabinet.
