Abstract:
1. An apparatus for transferring heat from a first fluid to a second fluid, which is separated from the first fluid, having a stack-like or saucer-like structure comprising at least two plies ( 1 , 2 , 3 ), in particular plates ( 1 , 2 , 3 ), whereby each ply ( 1 , 2 , 3 ) comprises a heat-transferring area that has a numerous passages ( 11 , 12 , 13 ), an inlet area located in front of the heating-transferring area in the direction of flow, and an exit area located behind the heat-transferring area in the direction of flow, wherein the inlet and/or exit area comprises at least one support element ( 18 ), and wherein said support element ( 18 ) is produced on or in the ply ( 1 , 2 , 3 ) by means of a removal or deposition production method, wherein said support elements ( 18 ) of two adjacent plies ( 1 , 2 , 3 ) extend in intersecting directions to reduce the exposed cross section ( 23 ) between two plies and therefore to reduce the bending stresses on the plies ( 1 , 2 , 3 ) in their inlet and exit area.
