A heat exchanger includes first flow ducts and adjacent second flow ducts for exchanging heat energy between first flows through the first flow ducts and second flows through the second flow ducts. A parallel flow region where flow passages and directions of the first flows and adjacent flow passages and directions of the second flows are arranged in a parallel relationship with respect to each other at least in a portion of the parallel flow region and are fluidly separated by wall portions. A cross section of the wall portions of the parallel flow region orthogonal to a local flow passage direction of the parallel flow region is a grid-like pattern including a group of m lines spaced from each other and a group of n lines spaced from each other, the m lines and the n lines defining a plurality of points of intersection and a boundary line section between two points of intersection, each boundary line section being part of a boundary line delimiting a cross section of a flow duct of the first and second flow ducts, wherein at least some of the boundary line sections are continuous lines having a positive slope portion and a negative slope portion with respect to a straight line between the two points of intersection.

Furthermore, the invention discloses a method for producing such enthalpy exchanger elements and enthalpy exchangers, comprising the steps of a) providing an air-permeable sheet element (); b) laminating at least one side () of the sheet element () with a thin polymer film () with water vapor transmission characteristics; and c) forming the laminated sheet element () into a desired shape exhibiting a three-dimensional corrugation pattern (, . . . ).

Enthalpy exchanger element, enthalpy exchanger comprising such elements and method for their production

The invention relates to an exchanger arrangement () for the heat transfer and/or selective material transfer between a first fluid (F) and a second fluid (F), which can flow through the arrangement (), said arrangement () being constituted of a multitude (n) of adjacent local exchanger elements (E, E, . . . , E). The exchanger arrangement () has at least in some sections a cylindrical shape or the shape of a segment thereof or a prismatic shape having a polygonal base or the shape of a segment thereof. The adjacent local exchanger elements (E, E, . . . , E) are flat structures that are either wedge-shaped or sheet-like.

Exchanger element for passenger compartment and passenger compartment equipped with such an exchanger element

The present invention provides enthalpy exchanger elements (E, E', PR, PF) and enthalpy exchangers comprising such elements. Furthermore, the invention discloses a method for producing such enthalpy exchanger elements and enthalpy exchangers, comprising the steps of a) providing an air-permeable sheet element (); b) laminating at least one side () of the sheet element () with a thin polymer film () with water vapor transmission characteristics; and c) forming the laminated sheet element () into a desired shape exhibiting a three-dimensional corrugation pattern (, . . . ).

The invention relates to a heat exchanger blockand to a heat recovery ventilation unitcomprising such a heat exchanger block. In the heat exchanger block, the individual flow cross-section (Q) of flow passages of said plurality of first air flow passages (AFP) in said parallel flow region (PF) and the individual flow cross-section (Q) of flow passages of said plurality of second air flow passages (AFP) in said parallel flow region (PF) gradually, preferably linearly, decrease along a straight line (x-x) perpendicular to the parallel air flow passages (AFPand AFP) and from said first wall (W) to said second wall (W) of the block.
