Background

The thermostat automatically regulates the water amount entering the radiator according to the temperature of cooling water, changes the circulation range of water to regulate the heat dissipating capacity of the cooling system and ensure that the engine works in a proper temperature range. The thermostat mainly used is a wax thermostat, when the cooling temperature is lower than a specified value, the refined paraffin in the thermostat temperature sensing body is in a solid state, the thermostat valve closes a channel between the engine and a radiator under the action of a spring, and the cooling liquid returns to the engine through a water pump to perform small circulation in the engine. When the temperature of the cooling liquid reaches a specified value, the paraffin begins to melt and gradually becomes liquid, the volume is increased along with the melting of the paraffin, and the rubber tube is pressed to shrink. When the rubber tube contracts, the rubber tube acts on the push rod with upward thrust, and the push rod pushes the valve downwards to open the valve. At this time, the cooling liquid flows back to the engine through the radiator and the thermostat valve and then through the water pump to perform large circulation. It follows that thermostats are important components in automotive cooling systems.

At present, most manufacturers at home adopt manual assembly, and because the number of assembly parts is large and the parts are small, similar assembly modes are adopted, the production efficiency is generally low, the working strength is high, and the production cost is high; and secondly, the condition that the double-cover parts are not easy to be installed and neglected to be installed and whether the installation is in place or not is difficult to detect is difficult to ensure, so that the condition of the thermostat is difficult to ensure.
