The use of aluminium cores for the manufacture of cooling radiators

Aluminium has become an essential ingredient in the manufacture of radiator cooling cores. Its good thermal conductivity allows it to compete with copper for price, weight and mechanical strength. The plate and bar technology introduced more than 25 years ago makes it possible to manufacture cooling radiators for different fluids and applications. One of the main features of the Plates and Bars brazed is its mechanical resistance which allows to withstand pressures of up to 30 bar. These aluminium cores make it possible to create oil cooling radiators for many industrial applications (compressors, boxes, engine oil, etc.). Despite the terminology used, not all radiators are used for cooling but also often for temperature regulation to optimize the operation of a complex thermal system.

The series of tubes and fins allows to realize a cooling radiator fully configurable in one or several parts, which allows not to be limited in dimensions. The main function of the fins, whose pitch can be adjusted according to the applications, is to amplify the heat transfer. The tube may or may not be equipped with a turbulator or disruptive device that further increases the thermal performance of the cooling radiator while ensuring greater customization.
