Abstract

The invention concerns a heat exchanger designed to be used in the cooling or heating system of internal combustion engines on motor vehicles. The heat exchanger described in this invention is characterized by a system, whose tube and turbulence promoter consist of optimal cross section elements designed to achieve a maximal thermal flow, a minimal air pressure drop and a reduced material consumption. The overall dimensions of the tubes and their positioning may be adapted to the vehicle the heat exchanger is destined for, so as to meet all requirements of the customers. The heat exchanger has a compact structure - in some cases it consists of only one row of tubes - and it provides a maximal efficiency thermal exchange.
