A Manufacturing Method for Automotive All Aluminum Water Tank Radiator

The present invention relates to the technical field of automotive radiator, in particular to an all aluminum water tank radiator for automobiles.

The car water tank, also known as the radiator, is the main component in the car cooling system; The function is to dissipate heat. Cooling water absorbs heat in the water jacket, flows to the radiator, dissipates heat, and then circulates back into the water jacket to achieve temperature regulation. It is a component of a car engine. The water tank is an important component of a water-cooled engine, and as an important component of the cooling circuit of a 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 increase after absorbing the heat of the cylinder block is not much. Therefore, the heat of the engine is transmitted through the cooling water circuit, which uses water as a heat carrier for heat transfer, and then dissipates heat by convection through a large area of heat dissipation fins, To maintain the appropriate operating temperature of the engine. All aluminum radiator is often used to dissipate heat from the car water tank.

However, the existing automotive all aluminum water tank radiators require welding of inlet and outlet channels on the water tank for water circulation. When welding the inlet and outlet channels, secondary welding is required, resulting in uneven product appearance, low assembly accuracy of the water tank and heat dissipation pipe, and prone to false welding problems. At the same time, the radiator undergoes certain stress due to thermal expansion, which can cause micro leakage defects after a period of product use. In view of this, we propose a car all aluminum water tank radiator.
