Workflow Of Cooling System

- Sep 01, 2017-

    In the whole cooling system, cooling medium is coolant, the main parts are thermostat, water pump, pump belt, radiator, cooling fan, water temperature sensor, liquid storage tank, heating device (similar to radiator). Coolant, also known as antifreeze, is a liquid composed of antifreeze additives and additives and water that prevent metal from rusting.Cooling System

    It needs to have antifreeze, corrosion resistance, heat conductivity and not metamorphic performance. Ethylene glycol is now often used as the main ingredient, with the addition of anti-corrosion and water antifreeze. Coolant water is the best use of soft water, can prevent the engine to create scale, resulting in heat transfer blocked, engine overheating. Adding antifreeze to water and increasing the boiling point of the coolant can play an additional role in preventing premature boiling of the coolant liquid. In addition, the coolant contains a foam inhibitor, can inhibit the air in the pump impeller stirring to produce foam, prevent the water jacket wall heat dissipation.Cooling System

    When the engine is working, the coolant flows through the radiator core, the air is passed through the radiator core, and the hot coolant cools out due to the air cooling. There is also an important small part on the radiator, which is the radiator lid, which is easily overlooked. As the temperature changes, the coolant will "shrink and shrink", radiator due to the expansion of the coolant pressure increase, internal pressure to a certain time, the radiator lid open, coolant flow to the storage tank; When the temperature drops, the coolant flows back into the radiator. If the coolant in the tank is not reduced, the radiator liquid surface is reduced, then the radiator lid will not work!Cooling System

    Engine work, the gas temperature in the cylinder can be up to 1727~2527c, if not in time cooling, will cause engine parts temperature is too high, especially the direct contact with high-temperature gas parts, will be due to thermal expansion of the normal coordination gap, resulting in movement pieces blocked or even stuck dead. In addition, the high temperature will cause the engine parts mechanical strength to drop, causes the lubricating oil to lose the function and so on.Cooling System
