Embodiment Construction

[0048] exist figure 1 , shows a view of a plate heat exchanger with a first conduit 2 and a second conduit 3 adjacent to each other for a first fluid 20 and a second fluid 30 flowing in parallel. A thermally conductive plate 1 made of a thermally conductive material such as a thin metal plate includes separators 5 arranged thereon. The separator 5 and the two spacers 55 are arranged along the entire length of the heat conducting plate 1 . The separator preferably separates the first conduit 2 and the second conduit 3 from each other in a fluid-tight manner. Depending on the position of the separator 5 relative to the lateral sides of the heat conducting plate 1, the width of the ducts 2, 3 can be defined. Two spacers 55 are arranged along the edges along the two lateral sides of the heat conducting plate 1 in order to close the first conduit 2 and the second conduit 3 along these lateral sides, preferably in a fluid-tight manner. The separator 5 comprises two separating ele...

Abstract

The heat exchanger comprises a cool conduit (2,3), a hot conduit (4) and a heat exchanging element (1) arranged between the cool conduit (2,3) and the hot conduit (4). The heat exchanger further comprises at least one further conduit (3,2) arranged next to the cool conduit (2,3) or to the hot conduit (4) on a same side of the heat exchanging element (1) as said respective cool or hot conduit. The further conduit is separated from the respective cool or hot conduit by a separator (5) comprising two separating elements (51,52) arranged at a distance to each other and forming a cavity (53) between the two separating elements (51,52). The separator restricts a fluid flow into or in the cavity (53) such as to limit a heat exchange between the further conduit (3,2) and the respective cool or hot conduit on the same side of the heat exchanging element (1).

Description

technical field [0001] The present invention relates to the field of heat exchangers. In particular, the invention relates to multi-flow heat exchangers. Background technique [0002] There are heat exchanger modules where two cold fluids are heated by one hot fluid. When one cold fluid should be heated less than the other cold fluid, the one fluid is arranged at the side of the hot fluid that has cooled down and the other cold fluid is arranged at the hot inlet side of the hot fluid place. These heat exchanger modules are suitable for heating two cold fluids but are not optimized for heat recovery from the hot fluid. [0003] There are known applications, for example, the operation of fuel cells providing two exhaust or exhaust fluids at elevated temperatures. The heat stored in each fluid is made available for further use by directing each fluid into a heat exchanger. Next to the fact that several heat exchangers are expensive and require space, these exhaust fluids a...
