Plate for evaporative heat exchanger and evaporative heat exchanger

摘要

A plate for an evaporative heat exchanger is stamped from a laminate material comprising a thin sheet of light-weight, heat conductive, formable metal such as aluminum superimposed on and attached to a thin sheet of wicking material. Stamping the laminate material simultaneously cuts the plate into a substantially square, pre-determined size, forms a series of ribs and corresponding recesses into the plate and blanks square notches into each corner of the plate to define four edges. The ribs are spaced apart in a substantially parallel manner, appear substantially semicircular in configuration and extend longitudinally and substantially across the plate. A method to fabricate said plate is also described. A plurality of said plates is stacked in a serial relationship and attached along corresponding edges at opposite ends to form alternating air conditioning channels and evaporative cooling channels defined by metal surfaces and wicking material surfaces respectively whereby the conditioned air flows perpendicularly to the secondary air and water.
