Car radiators belong to the car cooling system. The radiator in the engine water cooling system consists of three parts: the water inlet chamber, the water outlet chamber, the main fin and the radiator core. The radiator cools the coolant that has reached a high temperature. When the tubes and fins of the radiator are exposed to the airflow generated by the cooling fan and the airflow generated by the movement of the vehicle, the coolant in the radiator becomes cold.
In order to ensure the cooling effect, the automobile cooling system is generally composed of radiator, thermostat, cylinder head water channel, cylinder water channel, water pump, fan and so on. The radiator is responsible for the cooling of the circulating water. Its water pipes and radiating fins are mostly made of aluminum. The aluminum water pipes are made into a flat shape, and the radiating fins are corrugated, which pays attention to the heat dissipation performance. The radiator doubles as water storage and heat dissipation. An air vapor valve is arranged on the car radiator cover, and a common air hole is communicated with the atmosphere.
The radiator should have sufficient heat dissipation performance and a high service life in a limited space, so the entire radiator assembly must reduce the consumption of raw materials, improve the production process and structure, reduce production costs, and achieve thin-wall, light-weight, and high-efficiency. In the welding part, the method of expanding the welding area should be adopted to reduce the stress. For example, the main piece and the water chamber adopt the narrow groove form of double-sided welding to reduce the wall thickness as much as possible. The method of increasing the wall thickness is not allowed to increase the assembly. strength.
