Abstract

A heat exchanger, in particular an oil cooler for internal combustion engines, composed of several parallel tubes (19) for the heat exchange medium and of lamellar, plate-like heat exchange elements (10) arranged perpendicular to the tubes and fixed thereto. The heat exchange elements (10) are bent at their outer edges (11) and are nested on top of each other. An adapter element (13) is provided for supplying the medium to be cooled. The adapter element (13) has liquid inlet (15), a liquid outlet (18) and a mounting member (14) for the heat exchanger.

Claims

1. A heat exchanger comprising:

a plurality of heat exchange medium connections arranged parallel to one another for conducting a heat exchange medium to and from the heat exchanger;

a plurality of plate-like, lamellar heat exchange elements arranged perpendicularly to and fixedly attached to the heat exchange medium connections, said heat exchange elements being bent over at outer edges thereof and being nested one above another;

an adapter element consisting of a first flat plate having passageways formed therein leading from a fluid inlet to said heat exchange elements and from said heat exchange elements to a fluid outlet, said first flat plate being received and mounted within an end one of said plate-shaped heat exchange elements;

a mounting member for the heat exchanger consisting of a second flat plate abutted to a face of said adapter element;

duct means through which a fluid to be heat exchanged with said heat exchange medium is supplied to and discharged from the heat exchanger, said duct means being arranged perpendicularly to the heat exchange elements and communicating with the fluid inlet and the fluid outlet of said adapter element; and

a pressure relief valve arranged in the mounting member and extending into said adapter element.

2. A heat exchanger according to claim 1, wherein said heat exchange medium connections are arranged on an opposite side of said heat exchanger from said adapter element.

3. A heat exchanger according to claim 1, wherein said heat exchange medium connections, said heat exchange elements, and said adapter element are formed of solder-plated aluminum.

4. A heat exchanger according to claim 1, wherein said heat exchange elements and said heat exchange medium connections are formed of solder-plated aluminum.
