Definitions
- the present invention refers to a heat exchanger, in particular an air-to-air heat exchanger of the type with a pack of metal plates.
- heat exchangers of the plate pack type comprising a pile of metallic sheets, preferably of aluminium, substantially with a rectangular shape, as the one described in French patent 2 318 389.
- the various aluminium sheets are welded to each other in correspondence of a pair of opposite sides, in such a way so that the two flows of air, that must exchange heat with each other, are directed orthogonally to each other.
- the pack of sheets is sealed in correspondence of the corners by means of corner ribs that, in turn, connect a pair of metal panels, parallel to the aforementioned aluminium sheets, that act as refinishing.
- object of the following invention is to provide for a heat exchanger of the type described, that instead is not subject to problems with condensate.
- a heat exchanger composed of a pack of metal sheets laid one upon the other and spaced, each including two pairs of opposite sides and coupled alternatively to the adjacent sheets in correspondence of the first and of the second pair of opposite sides, of two covering panels for the sheet pack and of corner ribs for the connection of the panels, characterised in that each covering panel is soft and partially flexible, and it is essentially made of a layer of non-conductive material.
- the inside faces of the covering panels result to be thermally insulated with respect to the exchanger, and therefore do not present problems with the formation of condensate.
- covering panels of the type claimed allows to use sheets of non-conductive material, either with or without one or two layers of coating, currently available on the market, that can then be cut into the proper dimensions.
- the heat exchanger comprises a plurality of metal sheets 100 laid one upon the other, preferably of aluminium, which, as shown in Figures 2-4, have a plurality of bulges 101 serving the purpose to maintain the sheets themselves at a desired distance and to increase the surface useful to the exchange of heat; always referring to Figures 2-4, the sheets 100 comprise two pairs of opposite sides 3 and 4 and they are coupled alternatively to the adjacent sheets in correspondence of the first and of the second pair of opposite sides.
- a first plurality of channels defined by the welding zones between the pairs of sides 3 of the adjacent sheets for a first air flow 1 (Fig. 1) alternated with a second plurality of channels defined by the welding zones between the pairs of side 4 and that extend in a direction orthogonal to that of the channels of the first plurality for a second air flow 2.
- each covering panel is composed of three layers 5, 6 and 7: the outside layers 5 and 7 consist of two thin metal sheets, preferably of aluminium, having a certain degree of flexibility.
- the intermediate layer 6 is a layer of non-conductive material that serves the purpose to insulate thermally the exterior of the heat exchanger (in this case the layers 5 of the two panels 102) from the inside of the same, as to avoid the formation of condensate.
- each panel 102 will consist of the sole non-conductive material 6.
- the layer 6 can be coated only on one side, instead of both, either on the external or on the internal side.
