The water tank is an important part of the water-cooled engine. As an important part of the cooling circuit of the water-cooled engine, it can absorb the heat of the cylinder and prevent the engine from overheating. Because of the large specific heat capacity of water, the temperature of the engine does not rise much after absorbing the heat of the cylinder, so the heat of the engine passes through the liquid circuit of cooling water, and water is used as the heat carrier to conduct heat, and then the heat is dissipated by convection through a large area of fins to maintain the appropriate working temperature of the engine.
Automobile water tank, also known as radiator, is the main part of automobile cooling system, and its function is to dissipate heat. The cooling water absorbs heat in the water jacket, flows to the radiator and dissipates heat, and then returns to the water jacket for circulation, thus realizing temperature regulation. It is an integral part of an automobile engine.
