Automobile thermostat seat function
The main function of the automobile thermostat is to adjust the circulation path of the engine coolant to ensure that the engine works in the appropriate temperature range . Specifically, the thermostat automatically adjusts the amount of water entering the radiator according to the cooling water temperature, changing the water circulation range, thereby adjusting the cooling system's heat dissipation capacity. This can not only ensure that the engine operates within the appropriate temperature range, but also save energy, avoid excessive fuel consumption and damage to the vehicle .
Working principle of thermostat
The thermostat usually contains a temperature-sensing component that turns on or off the flow of coolant through the principle of thermal expansion and cold contraction. When the coolant temperature is lower than the set value, the thermostat is closed, the coolant circulates inside the engine, and the temperature rises rapidly; When the temperature reaches the set value, the thermostat opens and the coolant flows to the radiator for heat dissipation. When the temperature drops again, the thermostat closes again to keep the engine in the appropriate temperature range .
Installation position and maintenance method of thermostat
Automotive thermostat is generally installed in the upper outlet of the engine. In order to determine whether the thermostat is working normally, it can be checked by observing the flow of the coolant or using the immersion method. For example, if no cooling water flows out of the water pipe when the coolant temperature exceeds 70 ° C, the thermostat cannot be started .
In addition, it is also very important to choose the right thermostat type, because the best operating temperature of different engines is different, and the opening temperature of the thermostat needs to match accordingly .
Automobile thermostat holder is the base on which the thermostat is installed. It is used to fix the thermostat and ensure its normal operation. The thermostat holder is usually made of metal material and has sufficient strength and corrosion resistance to ensure stable operation under various working conditions.
The function and working principle of thermostat
The thermostat is an automatic temperature control device, which regulates the flow of coolant through the temperature sensing component to adjust the heat dissipation capacity of the cooling system. Its main function is to automatically adjust the flow path of the coolant according to the temperature of the engine to ensure that the engine works in a suitable temperature range. When the engine starts, the thermostat senses the low temperature, and closes the path to the radiator, so that the coolant directly circulates back to the engine for small circulation to rapidly heat up; When the temperature rises, the thermostat opens the path to the radiator for large circulation to increase the heat dissipation effect and prevent the engine from overheating .
Type and material of thermostat holder
There are a variety of types and materials of automotive thermostat seats, common materials include aluminum, copper, stainless steel and so on. These materials have good thermal conductivity and corrosion resistance, and can adapt to different working environments. For example, the aluminum thermostat is light in weight and has good thermal conductivity, but attention needs to be paid to prevent corrosion; Copper thermostat holder has strong corrosion resistance, but the weight is larger; Stainless steel thermostat holder combines the advantages of light weight and corrosion resistance .
Thermostat base installation and maintenance
When installing the thermostat base, it is necessary to ensure that it is closely matched with the engine to avoid leakage and loosening. In daily maintenance, the status of the thermostat base should be checked regularly to ensure that it is not damaged or aging, and replace it if necessary. In addition, keeping the engine cooling system clean and avoiding impurities from entering the cooling system is also an important measure to extend the service life of the thermostat holder .
