Automobile water tank, also known as radiator, is the main component of automobile cooling system; its function is to dissipate heat. The cooling water absorbs heat in the water jacket, flows to the radiator and dissipates the heat, and then returns to the water jacket to circulate to achieve temperature regulation . It is an integral part of the car engine.
The water tank is an important part of the water-cooled engine. As an important component of the heat dissipation circuit of the water-cooled engine, it can absorb the heat of the cylinder block and prevent the engine from overheating. Due to the large specific heat capacity of water, 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 cooling water, uses water as a heat carrier to conduct heat, and then dissipates heat in a convective manner through a large-area heat sink to maintain the proper operating temperature of the engine.
When the water temperature of the engine is high, the water pump circulates repeatedly to reduce the temperature of the engine (the water tank is composed of hollow copper pipes. The high-temperature water enters the water tank and circulates to the engine cylinder wall after being air-cooled) To achieve the purpose of protecting the engine, if the water temperature is too low in winter, the water circulation will be stopped at this time to avoid the engine temperature from being too low.
