Description

[0028] Further features and aspects of the invention become obvious from the following description of the drawings. The drawings show:

[0029] FIG. 1 a top view of one example for an embodiment of an exchanger plate according to the invention and

[0030] FIG. 2 a side view of the plate according to FIG. 1.

[0031] In the drawings, the same elements are designated by the same reference numbers.

[0032] An exchanger plate 1 consists of a structural rigid plate 2 made from aluminum, plastic or the like. Plate 2 has a rim 4 which is a flat sealable rim and can be deformed for sealing. Areas of the rim 4 are opened or deviated as shown by reference no. 5 to define e.g. a inlet and outlet of a flow channel.

[0033] Within the rim area, corrugations 3 are stamped or embossed into the plate 2. When plates are sealed together, flow channels are defined. In the example, reference no. 5 designates areas with perforations.

[0034] For the purpose of clarity, only some of the perforation areas 6 and some of the corrugated areas 3 are designated.

[0035] The heat exchanger element 1 shows a great surface tor heat exchange which is increased by the corrugations 3 which are corrugated in one direction only and open on the other surface. Furthermore, the perforated areas 6 define a latent energy exchange area for the transfer of moisture.

[0036] These plates will be stacked to build a heat exchanger e.g. for ventilation systems to exchange heat from outgoing to incoming air (or vice versa for free cooling in summer) as well as humidity from outgoing to incoming air in winter (or vice versa for moisture reduction in summer or all year round in hot and humid climatic tones).

[0037] The drawings and the description do in no way restrict the invention and are meant for describing an example, only.
