What Are the Requirements of Truck Radiator Manufacturers for Material Selection?

The heat transfer coefficient is an important parameter to evaluate the heat dissipation performance of truck radiators, and the thermal conductivity and welding quality of truck radiator materials have a great influence on it.


1. Material performance requirements of truck radiators


The working conditions of truck radiators are poor, and they are generally located at the front end of the car. They not only have to withstand wind, rain and pollution from car exhaust, but also withstand repeated thermal cycles and periodic vibration.


In addition, there is a long-term flow of coolant in the truck radiator, which has rust and corrosion effects on the truck radiator.


Therefore, in order to ensure the reliable performance of the heat dissipation effect of the truck radiator, the material properties of the truck radiator have the following requirements: it needs to have good thermal conductivity, a certain strength and strong corrosion resistance, and good processing performance and brazing properties. And it should be economical.


2. Commonly used material types for truck radiators


At present, the commonly used truck radiator materials mainly include copper, aluminum and engineering plastics. The use of materials with higher thermal conductivity for the radiator fin is also very helpful to improve the heat transfer efficiency. In terms of the thermal conductivity of metals, silver has a higher thermal conductivity, followed by copper and aluminum. Silver is expensive and is not suitable for heat dissipation materials. At present, copper, aluminum and aluminum alloys are more commonly used. The thermal conductivity of aluminum is low, but by adding fins to increase the heat dissipation area, it can also achieve a better heat dissipation effect.
