The heating and cooling system of car seats is mainly composed of switches, fan drivers, turbine fans, semiconductors, ventilation
pipes, exhaust pipes and other accessories.Its working principle is to use a fan to semiconductor blowing to achieve air
convection in the seat, thereby changing the seat surface temperature;By adjusting the switch to change the direction of the
voltage between the semiconductor poles to achieve hot and cold conversion.The single-chip microcomputer controls the fan and the
semiconductor to realize the shift position.
