方法，板元件和热/焓交换器。 a）在任何期望的区域和任何期望的尺寸下将具有限定的外部尺寸的未成形的板状元件穿孔; b）用具有潜在能量交换特性的薄聚合物膜覆盖未成形板元件的至少一侧; c）将板状元件形成所需的形状和波纹和/或压花图案。 操作b）和c）可以以不同的顺序执行。 例如，当板元件由塑料制成时，b）可以在c）之前执行，而当板元件由铝（或塑料）制成时，c）可以在b）之前进行。 在某些实施方案中，操作a）和/或b）和/或c）也可以组合。

Method, the plate elements and heat / enthalpy exchanger. a) a defined non-molded plate element having external dimensions comprising: puncturing within any desired area, and any desired dimensions; b) covering at least one side of the non-molded plate as a polymer thin film element having a latent heat energy exchange characteristics; And c) a plate element the desired shape, and wrinkles and / or the step of forming the embossed pattern. Step b) and c) may be performed in a different order. For example, when the plate elements made of plastics, b) when formed of a c), which may be previously performed on the other hand, the board element is aluminum (or plastic), c) it may be carried out prior to b). Step a) and / or b) and / or c) may also, in certain embodiments, be combined.
