What is a car thermostat
The automobile thermostat is a key component of temperature control in the automobile air conditioning system. Its main function is to adjust the temperature inside the car, prevent the evaporator from forming frost, and ensure the comfort in the cockpit. The thermostat adjusts the start and stop of the compressor by sensing the surface temperature of the evaporator. When the temperature inside the car reaches a preset value, the compressor is started to keep the air flowing through the evaporator; When the temperature is low, turn off the compressor timely and keep the temperature in the car balanced .
How a thermostat works
The thermostat controls the start and stop of the compressor by sensing the evaporator surface temperature, the interior temperature and the atmosphere temperature. When the temperature in the car rises to the set value, the thermostat contact closes and the compressor works; When the temperature drops below the set value, the contact is disconnected and the compressor stops working. Most thermostats have an absolutely off position that allows the blower to work even if the compressor is not working.
Type and structure of thermostat
There are many types of thermostats, including bellows, bimetal and thermistor. Each type has its own unique principles and application scenarios. For example, a bellows type thermostat uses temperature changes to drive the bellows and control the start and stop of the compressor through springs and contacts. Bimetallic thermostats use metal sheets with different thermal expansion coefficients to sense temperature changes .
Location and layout of the thermostat
The thermostat is usually placed on the cold air control panel in or near the evaporation box. In automotive cooling systems, thermostats are generally installed at the intersection of the engine exhaust pipe and are used to automatically regulate the amount of water entering the radiator, ensuring that the engine is operating within the proper temperature range .
The impact of thermostat failure
If the car thermostat fails, it may cause the temperature inside the car to fail to adjust, the compressor will not work properly, and even affect the comfort of the cockpit. Therefore, it is very important to check and maintain the thermostat regularly .
