Embodiment Construction

[0052] exist figure 1 In , the sequence of steps of the fabrication method according to the present invention is shown. figure 1 Each step shown in corresponds to figure 2 The resulting state shown schematically in . It should be noted that figure 2 Geometric parameters such as thickness, pore diameter, curvature, etc. described in are for exemplary purposes only. Accordingly, they do not necessarily indicate suitable or preferred ratios for these parameters.

[0053] In a providing step S1 a flat but unshaped sheet metal element 1 with defined outer dimensions is provided. In the piercing step S2, a part of the flat sheet metal element 1 is passed to a piercing device (not shown), where the flat sheet metal element 1 is punched by a punching die (not shown) selected according to the size of the hole required. shown) perforation. In the present case, the entire plate element 1 is perforated with a symmetrical hole pattern, except for border areas (not shown), to allow ...

Abstract

The invention provides an enthalpy exchanger element which allows the creation of an enthalpy exchanger whereby the efficiency of sensible and latent energy exchange can be varied and controlled and in particular improved. Furthermore, there is provided a method for making an enthalpy exchanger element, comprising: a) perforating a flat plate element (1) within the outer dimension of the plate according to a predetermined perforation pattern; b) shaping said plate element (1) into the desired embossing pattern and geometry; and c) applying a polymer film (3) having water vapor permeability properties (Water Vapor Transmission Ratio, WVTR) to at least one side (1a) of said plate element (1).

Description

technical field [0001] The present invention relates to enthalpy exchanger elements. Furthermore, the invention discloses a method for producing an enthalpy exchanger element. Finally, the invention relates to an enthalpy exchanger comprising an inventive enthalpy exchanger element. Background technique [0002] The prior art uses different kinds of heat exchangers for different purposes. Generally, heat exchangers are used to recover thermal energy from one fluid or medium to another fluid or medium. This thermal energy is called apparent energy. Thermal or sensible energy of one fluid (usually air) is recovered to another fluid extending adjacent (eg, in parallel, opposite or cross-flow) to a first fluid (which is at a lower temperature). By reversing the fluid flow, the exchange between the two will produce a cooler fluid. Heat exchangers for sensible energy recovery are usually made of metal or plastic plates. There are different types as there can be cross-flow, p...
