Abstract
A heat exchanger includes a plurality of tube elements, and a plurality of fins which are alternately stacked together with the tube elements. A tank element is disposed on both sides of the tube elements. At least one of the tank elements is formed of brazing materials and comprises a pair of plates which are U-shaped in cross-section and form an inner space. A partition plate is positioned in the inner space and divides the inner space into a first space adjacent the tube elements and a second space separated from the tube elements by the first space. The partition plate is also provided with a penetrating hole. Each of the tube elements contain at least first and second coolant flow passages. The first coolant flow passages extend through the penetrating holes and into the second space, and the second coolant flow passages extend into the first passage.
