Plate heat and mass exchanger with edge extension
First Claim
1. A heat exchanger plate for use in an indirect evaporative cooling system, the plate comprising:
- a dry side having low permeability to an evaporative liquid and formed to allow a product fluid to flow over a heat transfer area of its surface;
a wet side designed to have its surface wet by an evaporative liquid, and formed to allow a working gas to flow over its surface to evaporate the evaporative liquid; and
an edge extension formed at the edge of the plate, beyond the heat transfer area, for causing excess evaporative liquid to drip off the plate.

Abstract
Heat exchanger plates for indirect evaporative coolers, of the type having a dry side having low permeability to an evaporative liquid and formed to allow a product fluid to flow over a heat transfer area of its surface, a wet side designed to have its surface wet by an evaporative liquid, and formed to allow a working gas to flow over its surface to evaporate the evaporative liquid, further include edge extensions formed beyond the heat exchange area of the plates to facilitate removal of excess evaporative liquid. The edge extensions may slant or curve away from the wet side of the plates to assist in liquid removal. The plates may be used in a variety of configurations.

10. An indirect evaporative cooler comprising:
-
a plurality of generally parallel, spaced apart plates wherein each plate has a dry side having low permeability to an evaporative liquid and formed to allow a product fluid to flow over a heat transfer area of its surface;
a wet side designed to have its surface wet by an evaporative liquid, and formed to allow a working gas to flow over its surface to evaporate the evaporative liquid; and
an edge extension formed at the edge of the plate, beyond the heat transfer area, for causing excess evaporative liquid to drip off the plate;
wherein the edge extensions extend beyond the edge of the heat transfer areas of the plates for a distance at least the distance between the plates. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
