The development of automobile lightweight technology and the requirements for energy saving and consumption reduction have promoted the 100% aluminum alloy heat exchanger of passenger car air conditioning in my country. Traditional automobile heat exchangers have always used copper alloys, and automobile radiators use composite aluminum pipe tube instead of copper alloys, which can reduce the quality by 20% to 45%.


The automobile heat exchange system includes condenser, evaporator, water tank radiator, intercooler, heater, oil cooler and other components. The automobile aluminum heat exchanger is composed of aluminum pipes for cooling water and heat sinks for heat dissipation. , Aluminum tubes are generally made of 1xxx and 3xxx series aluminum alloys by extrusion and drawing.

The brazing technology of automotive tube-strip heat exchangers has successfully solved the corrosion resistance of aluminum alloy radiators. It is a high-end product of aluminum processing products with high technical content and high added value.
