PANEL FOR REGENERATIVE HEAT-EXCHANGERS

摘要

A heat exchange panel or element is adapted for use in a regenerative or recuperative type heat exchanger and is particularly suitable for use in a gas to gas, vapour bearing gas to gas, or gas or vapour bearing gas to air heat exchanger of the Ljungstrom or similar type. The panel or element comprises a composite wall member (9) made of metal mesh (10) and an encapsulating layer (11) of a material of lower thermal conductivity which envelopes and extends through the mesh, the layer thickness outside the mesh being thin and substantially less than the thickness of the mesh so that the mesh extends substantially to, and conducts heat from, the outer surfaces of the wall member. The mesh (10) may be interwoven metal strands or strips or be of pierced and expanded, preferably flattened, metal sheet. In one form immediately next to the mesh (10) the encapsulating layer is a filled plastics material to promote heat capacity and outside the mesh (10) the layer is of a corrosion resistant inert material.
