Embodiment Construction

[0023] Figure 1 schematically shows a plate heat exchanger according to an exemplary embodiment of the present invention. The plate heat exchanger generally comprises a plurality of plates 1 arranged parallel to one another. The plate 1 forms a hexagonal shape, but any other shape can also be selected. The cavity created by the plate is shown in the figure 2 Among them, the reference number 2 represents the closed side wall placed opposite.

[0024] figure 2 A schematic partial view of the principle of a plate heat exchanger according to FIG. 1 is shown, with fewer plates 1 than shown in FIG. 1 . Between the side walls 2 , two pairs of plates 1 are welded together at their side end regions 3 and fastened to the outer wall 2 . Other configurations (such as glued joints) are also conceivable. This results in a cavity structure between the corresponding pair of plates 1, which are in figure 2 Marked by shading. These cavities denoted by reference numeral 4 can, for example...

Abstract

The invention relates to a plate heat exchanger for exchanging heat between a first air stream (11, 12) and a second air stream (13, 14) comprising a plurality of plates (1) limiting exchange chambers which are serially arranged in a transversal direction with respect to said plates (1). The first air stream passes through one part of the exchange chambers (11, 12), the second air stream passes through the other exchange chambers (13, 14), preferably in an opposite direction. The second air stream consists of the air (13) removed from ventilated premises. A water distribution system (20, 21) is used for supplying water to the exchange chambers of the second air stream (13, 14) in such a way that the removed air is cooled by contact and evaporation, thereby lowering the external air temperature.

Description

[0001] This application is a divisional application of an invention application with an international filing date of March 22, 2004, an international application number of PCT / CH2004 / 000173, a national application number of 200480006599.4, and a title of "plate heat exchanger". technical field [0002] The invention relates to a plate heat exchanger for exchanging heat between a first and a second gas flow, with a plurality of plates delimiting exchange chambers, said exchange chambers being alternated with respect to the transverse direction of said plates At intervals, a first airflow may flow through some exchange chambers and a second airflow may flow through the remaining exchange chambers, said second airflow containing exhaust air from the room to be ventilated, which is exchanged by a plate heat exchanger room, as exhaust gas to the outside of the room to be ventilated. Background technique [0003] Plate heat exchangers are well known in the prior art, by means of w...
