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 ( 1 a, 1 b ) and have two opposite longitudinal sides (L 1 , L 2 ) and two opposite narrow sides (S), with one of the longitudinal sides (L 1 ) 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 ( 4 a, 4 b ) of the tubes ( 1 ) or of the plates ( 1 a, 1 b ), characterized in that at least the one end ( 4 a ) of the tubes ( 1 ) opens out in the longitudinal side (L 2 ) which is remote from the inflow side (A), and in that the other end ( 4 b ) of the tubes ( 1 ) either likewise opens out in the remote longitudinal side (L 2 ) or in the longitudinal side (L 1 ) which forms the inflow side (A) or in one of the narrow sides (S). The heat exchanger has comparatively large heat transfer faces.

1 . A heat exchanger for motor vehicles, for example a charge air cooler or cooling liquid cooler, the heat exchanger comprising:
 a plurality of tubes, each of which is formed from a pair of plates and has two opposite longitudinal sides and two opposite narrow sides, with one of the longitudinal sides constituting an inflow side for cooling air and composed of heat transfer fins arranged between the tubes and through which the cooling air flows freely, and composed of collecting spaces which are formed on the ends of the tubes or of the plates,   wherein at least the one end of the tubes opens out in the longitudinal side which is remote from the inflow side, and in that an other end of the tubes either likewise opens out in the remote longitudinal side or in the longitudinal side which forms the inflow side or in one of the narrow sides.   
   
   
       2 . The heat exchanger according to  claim 1 , wherein a collecting tank which forms the collecting space is attached to each end. 
   
   
       3 . The heat exchanger according to  claim 1 , wherein both ends of the tubes open out in the longitudinal sides, and wherein collecting tanks are arranged at both ends. 
   
   
       4 . The heat exchanger according to  claim 1 , wherein both ends of the tubes open out in the longitudinal side which is remote from the inflow side of the cooling air, and wherein collecting tanks are attached to both ends. 
   
   
       5 . The heat exchanger according to  claim 1 , wherein that end of the tubes or of the plates which opens out in one longitudinal side has at least one of a bent, curved and angled contour. 
   
   
       6 . The heat exchanger according to  claim 1 , wherein the heat transfer fins are also arranged between the tubes in the regions which have the angled contour. 
   
   
       7 . The heat exchanger according to  claim 1 , wherein the plates which form the tubes are configured to be of one of approximately L-shaped, approximately U-shaped, and approximately Z-shaped form. 
   
   
       8 . The heat exchanger according to  claim 1 , wherein the configuration of the plates which form the tubes has a convex contour. 
   
   
       9 . A cooling module for motor vehicles, the cooling module comprising:
 a plurality of tubes, each of which is formed from a pair of plates and has two opposite longitudinal sides and two opposite narrow sides, with one of the longitudinal sides constituting an inflow side for cooling air and composed of heat transfer fins arranged between the tubes and through which the cooling air flows freely, and composed of collecting spaces which are formed on the ends of the tubes or of the plates,   wherein at least the one end of the tubes opens out in the longitudinal side which is remote from the inflow side, and in that an other end of the tubes either likewise opens out in the remote longitudinal side or in the longitudinal side which forms the inflow side or in one of the narrow sides.   
   
   
       10 . The cooling module according to  claim 9 , wherein a collecting tank which forms the collecting space is attached to each end. 
   
   
       11 . The cooling module according to  claim 9 , wherein both ends of the tubes open out in the longitudinal sides, and wherein collecting tanks are arranged at both ends. 
   
   
       12 . The cooling module according to  claim 9 , wherein both ends of the tubes open out in the longitudinal side which is remote from the inflow side of the cooling air, and wherein collecting tanks are attached to both ends. 
   
   
       13 . The cooling module according to  claim 9 , wherein that end of the tubes or of the plates which opens out in one longitudinal side has at least one of a bent, curved and angled contour. 
   
   
       14 . The cooling module according to  claim 9 , wherein the heat transfer fins are also arranged between the tubes in the regions which have the angled contour. 
   
   
       15 . The cooling module according to  claim 9 , wherein the plates which form the tubes are configured to be of one of approximately L-shaped, approximately U-shaped, and approximately Z-shaped form. 
   
   
       16 . The cooling module according to  claim 9 , wherein the configuration of the plates which form the tubes has a convex contour.
