The invention relates to a counter flow enthalpy exchanger (1) having a parallelogram-shaped central part (11), whose ends in the flow direction through the exchanger it is joined by end parts (12, 13), which become narrower in the direction from the central part (11), whereby in order to separate the flow of the heat-transfer medium in the direction from the inner space to the outer space are arranged contour identical and with respect to the flowing medium sealed vapour-permeable lamellae (10) with shaping means for generating turbulent flow, whereby every two adjacent lamellae (10) form one interplate flow channel in the central part (11) one interplate flow channel. The lamella (10) is made as a one-piece self-supporting moulding common to the central part (11) and the end parts (12, 13), whereby it does not have a reinforcing support grid. Two adjacent lamellae (10) form one interplate flow channel in the end part (12, 13), in the walls of which are formed straight protrusions (121, 131) situated in the direction of the heat-transfer medium flow between the central part (11) and corresponding inlet or outlet of this medium.
The counter flow enthalpy exchanger (1), having a central part (11) shaped as a rectangular quadrangle, at whose ends it is joined in the flow direction through the exchanger by end parts (12, 13), which become narrower in the direction from the central part (11), whereby for the separation of the flow of the heat transfer medium in the direction from the inner space to the outer space are arranged vapour-permeable lamellae (10) with the same area contour which are sealed with respect to the flowing medium and have shaping means for generating turbulent flow, whereby every two adjacent lamellae (10) form in the central part (11) one interplate flow channel characterized in that the lamella (10) is designed as a one-piece self-supporting moulding common to the central part (11) and the end parts (12, 13) without a reinforcing support grid, whereby every two adjacent lamellae (10) constitute in the end part (12, 13) one interplate flow channel, in whose walls are formed straight protrusions (121, 131) situated in the direction of the flow of the heat-transfer medium between the central part (11) and the corresponding inlet or outlet of this medium.
