Car solar energy ventilation system

The utility model provides a car solar energy ventilation system is provided with buck circuit and ultracapacitor system between solar panel and switching circuit, the output and the ultracapacitor system of buck circuit are connected, and ultracapacitor system still is connected with the one end of switching circuit, be provided with the staring switch between lithium cell and the switching circuit, the lithium cell is connected with the input of staring switch, and the output of staring switch is connected with the one end of switching circuit, the staring switch is in the work that flame -out state or priming state controlled the air -blower respectively at the car, and through the detection of temperature sensor to car inside temperature, the control car is inside to ventilate, and the electric energy among the ultracapacitor system passes through photoelectric conversion by solar panel and supplyes the energy, has realized effective utilization of solar energy, and the utility model discloses an overcome reaching cloudy fine waiting the not general adjustment of weather conditions round the clock on deciding the degree, after the staring switch closure, supplied power to the air -blower by the lithium cell, ultracapacitor system gets into and supplyes the electric energy stage, and realization air -blower power supply intelligence is switched.
