Embodiment Construction

[0031]Figure 1 shows part of a heat exchange element 1 according to the invention in an unfolded state. The heat exchange element 1 comprises a membrane 10 having a first surface 12 and a second surface 14 . The membrane 10 is made of a thin gauge metal sheet, eg copper or aluminium. Both sides of the film 10 are provided with cooling fins 16 arranged in strips 18 . Strip 18 may be secured to film 10 in any suitable manner, but it will be found to be particularly advantageous if hot melt adhesive is used. To this end, the heat sink 16 is made of metal such as aluminum, laminated with hot-melt adhesive. Although metals have been found to be preferred for the manufacture of the membrane 10 and heat sink 16, it should be noted that other materials including plastic materials may be used, as described in previous applications WO 03 / 091648 A and WO 10 / 57461 A, the entire contents of which are incorporated herein as refer to. In this respect, heat transfer between the cooling fi...

Abstract

The invention provides a heat exchange unit (51) comprising a membrane (10) provided with heat conducting protrusions (16) on both surfaces thereof. The membrane (10) is folded in concertina like fashion to form a heat exchange element (1) having a plurality of primary (34) and secondary fluid (36) channels thermally connected to one another through the membrane (10). The folded heat exchange element (10) may be located within a housing (50) provided with suitable inlet and outlet apertures.

Description

technical field [0001] The invention relates to a heat exchange unit and a method of manufacturing such a heat exchange unit, in particular for the exchange of heat between two fluids flowing in an evaporative heat exchanger. Background technique [0002] Heat exchangers for exchanging heat between two fluid streams in which a dividing wall separates the two fluid streams are generally known. In general, the goal of many such devices is to increase the surface area of ​​the dividing wall to increase the effective heat transfer between the two fluids. Usually the walls are thin to maximize the temperature gradient, in which case the thermal conductivity of the wall material is not critical if the total area is large enough. EP0777094 discloses a device using a sheet folded into multiple layers to create a heat exchange element for heat recovery purposes. The sheet is made of Japanese Paper or the like, and ribs may be formed to ensure that the layers are spaced apart. [0...
