What is the purpose of a therm
English Public
The thermostat is a valve that controls the flow path of the engine coolant. The part automatically adjusts the amount of water entering the radiator according to the temperature of the cooling water to ensure that the engine works in a suitable temperature range and can save energy consumption. Because the engine is very fuel-intensive at low temperatures, the damage to the car is larger, including easily producing carbon deposits and bringing a series of problems. Therefore, the thermostat must be kept in good working condition, otherwise, it will seriously affect the normal operation of the engine.
Working principle of thermostat
To understand the working principle of the thermostat, we must first understand the structure of the thermostat.
There are two kinds of temperature savers: spring box type and wax type. We widely use wax type temperature saver, which is installed at the water outlet of the cylinder head. Wax thermal sensitive material has the characteristics of accurate temperature control, stable work, heat, pressure, frost resistance, long service life and so on. It is mainly composed of a main valve, auxiliary valve, support, spring, and induction body.
The induction body is a rigid sealed space composed of the induction body shell and cover. The upper end of the guide rod is connected to the main valve, and the lower end is covered with a rubber tube. The annular space formed by the rubber tube and the induction shell is filled with low-melting ash and paraffin wax or a mixture of aluminum powder and paraffin wax. One end of the spring is supported on the housing, and the other end is pressed on the spring seat on the main valve, and the main and auxiliary valves are linked with the guide rod.
The operation of the thermostat
When the outlet temperature is lower than 80℃, the main valve is closed and the auxiliary valve is fully opened. Cooling water does not go through the radiator, directly back to the pump for small circulation. When the outlet temperature is higher than 84℃, the paraffin mixture begins to melt, and the volume expansion extrusion hose produces an axial component force on the guide rod cone, forcing the guide rod compression spring to move upward, and the main valve opened and the small auxiliary valve is closed.
What happens if I drive my car without a thermostat?
A car without a thermostat will not allow the engine to operate at optimum temperature. It can also cause the heater to emit cold air.
