The invention relates to a plate heat exchanger for a motor vehicle, comprising conducting devices ( 3, 4 ) in the form of elongate disks which are stacked on top of each other and soldered together. The disks are composed of two elongate half disks ( 41 ) that form a hollow space for conducting a medium therethrough. Each end of each half disk ( 41 ) is provided with a first through-hole ( 48; 49 ) for feeding or discharging the medium, each through-hole ( 48; 49 ) being disposed between two other through-holes ( 55, 56; 60, 61 ). In order to create a plate heat exchanger that has a simple design and can be produced at a low cost, an edge region ( 57, 58; 62, 63 ) of the other through-holes ( 55, 56; 60, 61 ) is embodied in a raised manner and is substantially provided with the shape of a pot encompassing a bottom in which the associated through-hole is recessed. |
