Technical Dictionary Components of the cooling system Water Pump. Water Pump centrifugal circulates coolant for cooling system Radiator. All models are made of light metal. The radiator consists of two tanks, each connected with a plurality of thin-walled tubes. To increase the cooling surface between the tubes inserted folded accordion plates that collect excess heat and give it to counter the flow of air. The radiator is mounted on the upper and lower crossbeams. Thermostat. This depends on the temperature controller controls the coolant circuit. At temperatures up to + 85 ?� C the thermostat valve shuts off the radiator and the coolant circulates in a closed circuit (motor). At a temperature of +85 to + 100 ?� C thermostat partially opens the coolant to the radiator. Passage to the water pump remains in more or less open. Cold liquid from the radiator gradually mixed with the warm coolant before entering the engine. Thermostat valve is completely opened at temperatures above 100 ?� C, in this case the entire coolant flows through the radiator. Expansion tank. It adds the necessary amount of cooling fluid circulating in the cooling system. The excess pressure generated by the expansion tank, pressure relief valve is leveled, located in the lid of the tank. The radiator fan. Designed for more efficient cooling radiator air. Depending on the type of engine and vehicle equipment installed fan with viscous coupling or motor. |
