Working principle of water tank

The water tank is an important part of the water-cooled engine. As an important component of the cooling circuit of the water-cooled engine, it can absorb the heat of the cylinder block and prevent the engine from overheating. Because the specific heat capacity of the water is large, the temperature rise after absorbing the heat of the cylinder block is not much. Therefore, the heat of the engine passes through the liquid circuit of the cooling water, which uses the water as the heat carrier to conduct heat, and then passes through The heat sink with too large area dissipates heat by convection to maintain the proper working temperature of the engine.

When the water temperature of the engine is high, the water pump repeatedly circulates to reduce the temperature of the engine. If the water temperature is too low in winter, the water circulation will be stopped to avoid the engine temperature too low.
