2. Water tank is an important part of water-cooled engine. As an important part of the cooling circuit of water-cooled engine, it can absorb the heat of the cylinder block and prevent the engine from overheating. Because of the large specific heat capacity of water, the temperature did not rise much after absorbing the heat of the cylinder block.
3. Therefore, the heat of the engine passes through the liquid loop of the 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, so as to maintain the proper working temperature of the engine.
