Heat exchanger for motor vehicles

Abstract

The invention relates to a heat exchanger for motor vehicles, for example a charge air cooler or cooling liquid cooler, composed of tubes (1) which are formed from in each case two plates (1a, 1b) and have two opposite longitudinal sides (L1, L2) and two opposite narrow sides (S), with one of the longitudinal sides (L1) constituting the inflow side (A) for cooling air, for example, and composed of heat transfer fins (2) or the like which are arranged between the tubes (1) and through which the cooling air flows freely, and composed of collecting spaces (3) which are formed on the ends (4a, 4b) of the tubes (1) or of the plates (1a, 1b), characterized in that at least the one end (4a) of the tubes (1) opens out in the longitudinal side (L2) which is remote from the inflow side (A), and in that the other end (4b) of the tubes (1) either likewise opens out in the remote longitudinal side (L2) or in the longitudinal side (L1) which forms the inflow side (A) or in one of the narrow sides (S). The heat exchanger has comparatively large heat transfer faces.
