Stacked heat exchanger

#This nonprovisional application claims priority under 35 U.S.C. §119(a) to German Patent Application No. DE 20 2011 005 693.7, which was filed in Germany on Apr. 28, 2011, and which is herein incorporated by reference.

#Field of the Invention

#The invention relates to a stacked heat exchanger, in particular welded, ferritic heat exchanger for high temperature applications.

#The present invention will become more fully understood from the detailed description given hereinbelow and the accompanying drawings which are given by way of illustration only, and thus, are not limitive of the present invention, and wherein

#FIG. 1 illustrates a stacked heat exchanger according to an embodiment of the present invention.

#FIG. 2 is a block diagram illustrating a stacked heat exchanger according to an embodiment of the present invention with a high temperature fuel sells in a mobile vehicle.

#FIG. 1 shows a stacked heat exchanger 1 with its individual components in an exploded view. The stacked heat exchanger 1 consists, on the one hand, of an approximately cubic or cuboid layered block 2, which is bounded by four side faces and two cover faces. Header boxes 3, 4, 5, 6, which serve to supply and remove a first and a second heat exchange medium, are placed on the four side faces. The cover faces are sealed by cover plates 7, 8. The layered block 2 is shown in an exploded view above the stacked heat exchanger 1 as a stack consisting of contoured stack plates 9, 10 and the two cover plates 7, 8. Only two stack plates 9, 10 with differently oriented contouring (webs and channels) are shown in the drawing—in actuality, the stack or layered block 2 naturally has a number of stack plates. For example, the layered block 2 can be completed and restrained in a fixture that is not shown. The stack is fixed in place thereafter.

#In this design, the cover plates 7, 8, or the housing 11 composed of the individual elements, of the stacked heat exchanger 1 have a certain aluminum content that is already present before the first operational use.

#The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims.
