The automotive industry includes all types of vehicles from light to heavy duty as well as hybrid and electric vehicles.

Demand for heat exchanger material is strongly linked to global vehicle production and the number of heat exchangers per vehicle. A number of unique heat exchangers are developed for each new vehicle platform. This work is carried out in close collaboration with the customers to ensure that the final product has the right charactertistics. Advanced requirements in respect of the products’ characteristics, particularly in terms of energy efficiency, means that aluminium brazing technology is clearly dominant in the heat exchanger industry today. Increased cost efficiency, reduced weight and more efficient heat exchangers have been the driving forces.

The inside story

Modern vehicles typically contain up to ten different heat exchangers, sometimes more. In recent years, the number of heat exchangers per vehicle has increased, as engines have become more advanced, and environmental requirements and passenger comfort demands have grown. There are heat exchangers for cooling engines, transmission mechanisms and engine oil, air conditioning systems, and in some cases, batteries. Today, Gränges is a world leader in heat exchanger materials, and around 90 % of sales are to customers in the automotive industry.
