THERMOSTAT DEVICE FOR AUTOMOTIVE VEHICLE COOLING SYSTEM, COOLING SYSTEM EQUIPPED WITH SUCH A THERMOSTAT DEVICE AND METHOD OF CONTROLLING A HEATING MODULE

摘要

The invention relates to a thermostat device (4) for a motor vehicle cooling system comprising a valve, a heat-sensitive part, designed to cause the valve to open when the temperature of said sensitive part exceeds a temperature threshold. , and a controlled heating module of said sensitive part. A control module (40) is designed to control the heating module so that it delivers a non-zero heat output insufficient to cause an opening of the valve. A cooling system and a method of controlling a heating module are also described.
