When the car is exposed to the sun in the open parking lot and other places, it can be directly powered by solar panels 30 through devices such as temperature sensors installed in the car to sense the temperature in the car. When the temperature in the car reaches a certain value Make described solar heat dissipation device start working, at this moment solar panel 30 provides the electric energy needed for operation for solar heat dissipation device, please combine the air flow direction in the car indicated by the arrow among Fig. 2, wherein, the inside of car The hot air passes through the cooling block 21 for heat exchange and cooling, and after becoming cold air, it is discharged through the cross-flow fan 24, thereby reducing the temperature of the air in the car; , due to the Peltier effect, there will be a temperature difference between its two ends, and the low-temperature end of the semiconductor cooling chip 22 connected to the cold conduction block 21 will transmit and absorb the heat generated by the cold conduction block 21 due to heat exchange with the air, ensuring the temperature of the cold conduction block 21 cooling effect, and through the radiator 23 to dissipate heat from the high temperature end of the semiconductor cooling chip 22, to maintain the normal operation of the semiconductor cooling chip 22.
