Abstract

A heat exchanger (10) connectable with at least one connecting element (11). The heat exchanger is made up of a stacked structure and has holding devices (17) embodied as part of a heat exchanger housing. The holding devices can be produced by deforming an end plate (18) of the heat exchanger or they may be soldered on the end plate (18) in the form of profiled strips (24). The connecting element has corresponding locating elements (19), and assembly is carried out by deforming the holding devices (17) or by configuring the holding devices in the form of a bayonet lock. The integration of the holding devices (17) into the end plate (18) of the heat exchanger has the advantage of reducing manufacturing costs and simplifying assembly.

Claims

1. A heat exchanger comprised of stacked and soldered blanks and at least one end plate, said heat exchanger having at least one inlet and at least one outlet for a fluid to be cooled, at least one coolant inlet and at least one coolant outlet, wherein at least one connecting element is connectable to the inlet or outlet for fluid to be cooled by connection means comprising a plurality of holding devices constructed as part of the end plate, and a plurality of locating elements on said connecting element which form a positive interlock with the holding devices essentially without deformation of the locating elements, wherein at least part of the holding devices is formed by a profiled strip permanently attached to the heat exchanger.

2. A heat exchanger according to claim 1, wherein said profiled strip is soldered to the heat exchanger.
