As a professional car engine thermostat manufacturer, we provide various types of engine coolant thermostat. Wax thermostat is the first generation thermostat type. When the coolant temperature rises, the wax pellet gradually melts, changing the channel path of the coolant to the radiator. However, there are delays and hysteresis in the process of opening and closing the channel, which restricts the cooling performance of the engine cooling system.
Electronic thermostat, which directly controls the valve opening through the motor to achieve closed-loop feedback control of the car engine. According to engine operating condition and external temperature, electronic thermostat can adjust valve opening automatically. The durability and reliability verification of the design scheme is very important for motor driven valve thermostat.
