Influence of Welding Quality of the Radiating Tube and the Radiating Belt Ability of Car Radiator

Car radiator is an important component of engine cooling system. How it works depends on the configuration of the entire engine's cooling system. Such as the cooling fan, the windshield, the air flow passage of the engine compartment, the installation position of the engine on the car, the pipeline connecting the car radiator and the engine, and even the engine water pump. Therefore, the external environment of the radiator must be fully considered when designing a car radiator.


1. Introduction of car radiator


The selection and matching of the radiating tube and the radiating belt of car radiator elements directly affects the heat dissipation capacity of the car radiator. At the same time, the car radiator is not an isolated part, and instead it must be combined with other parts of the cooling system to complete the heat dissipation of the car engine. Therefore, the entire cooling system must be considered when designing a vehicle radiator.


2. The influence of the welding quality of the radiating tube and the radiating belt on the heat dissipation capacity of the car radiator


The heat of the cooling water is transferred to the outer wall through the inner wall of the radiating pipe, and is conducted to the radiating belt through the contact point between the outer wall and the radiating belt. If the radiating tube of the car radiator is not well welded to the radiating belt, a large thermal resistance will be produced. The most direct impact is that the temperature of the radiating belt is lower and the efficiency of the radiating belt decreases. Practical experience has proved that the welding quality of the radiating tube and the radiator belt of the car radiator influences 30-40% heat dissipation of the radiator core. Therefore, improving the welding quality of the radiating tube and the radiating belt of the car radiator element is a very important means to improve the heat dissipation capacity of the car radiator. Moreover, this measure is one-way, increasing the welding rate has no effect on the entire system.
