What is the role of car radiator?

Cars or other objects will generate heat during operation, so there is the appearance of car radiators. Then, the role of car radiators is only to dissipate heat? Let me introduce to you.

1 .Introduction 

The engine generally uses an internal combustion engine, which uses the heat generated by combustion to perform work. However, the effective power is only 30%-40% of the total energy of the fuel, and the remaining energy is consumed as exhaust heat loss and mechanical friction heat loss. In particular, in order to maintain proper temperatures of cylinders, cylinder heads, and intake and exhaust valves, it is necessary to cool various parts of the internal combustion engine, and thus heat energy is lost as a coolant.

2. Principle

According to the research findings, the current electric car radiator is generally made of aluminum alloy. The water pipe and heat sink are mostly made of aluminum. The aluminum water pipe is made into a flat shape with a corrugated heat sink. Pay attention to heat dissipation performance and installation direction. Vertical to the direction of air flow, try to make the wind resistance small and the cooling efficiency high. Coolant flows in the radiator core, and air passes outside the radiator core. The hot coolant becomes cold by dissipating heat to the air, while the cold air heats up by absorbing the heat dissipated by the coolant, and heat dissipation is achieved through the overall circulation.


As the electric vehicle radiator is an important component of the automobile water-cooled engine cooling system, and with the development of the Chinese automobile market, electric vehicle radiators have also begun to develop in the direction of lightness, cost-effectiveness and convenience. At present, electric vehicle heat dissipation There are mainly two types of DC type and cross-flow type. The core structure of the heat exchanger has two types: tube-fin type and tube-band type. The core of the tube-fin radiator consists of many thin cooling tubes and fins. The cooling tube adopts an oblate cross section to reduce air resistance and increase heat transfer area.


The above is the content of the car radiator for everyone. From the introduction, everyone should also have a certain understanding. When using the car, everyone should pay attention to the maintenance.
