In heat transfer devices, which are constructed as plate oil coolers for motor vehicles, an adapter plate is provided in order to achieve a compact construction with a joint fastening and with feeding openings which are accessible only from one side. The adapter plate is configured such that at least two, but preferably four different plate coolers can be supplied with the same coolant flow. This results in a particularly simple and compact construction.

Heat transfer arrangement and method of making same

A heat exchanger has flat tubes arranged in parallel to one another and at a distance from one another. The flat tubes are provided in the area of their ends with connection openings to adjacent flat tubes to avoid difficulties with respect to the tight closing of the open front ends, massive slide-in parts are introduced into the open tube ends. The walls of the flat tubes at least on the narrow sides against the slide-in parts. The slide-in parts therefore act as adapting pieces which determine the final form of the tubes. They cause a tight and pressure-resistant connection after the soldering.
