Abstract:
1. An evaporator comprising: a first plate having a first configuration including a first peripheral lip extending along the periphery of said first plate, a first center portion recessed with respect to said lip and having first and second ends, and a width, a first return trough recessed with respect to said center portion and having a first return aperture positioned at a bottom of said first return trough, first and second inlet troughs adjacent said second end and recessed with respect to said center portion with inlet apertures disposed in each inlet trough, a first outlet trough disposed between said first and second inlet troughs and recessed with respect to said center portion with an outlet aperture disposed in said outlet trough, and a first mound projecting from said center portion and surrounding said outlet trough; a second plate having a second configuration including a second peripheral lip extending along the periphery of said second plate, a second center portion recessed with respect to said second lip and having third and fourth ends, and a second width, a second return trough recessed with respect to said second center portion and having a second return aperture positioned at a bottom of said second return trough, third and fourth inlet troughs adjacent said fourth end and recessed with respect to said second center portion with inlet apertures disposed in each inlet trough, a second outlet trough disposed between said third and fourth inlet troughs and recessed with respect to said second center portion with a second outlet aperture disposed in said second outlet trough, a second mound projecting from said second center portion and surrounding said third inlet trough, and a third mound projecting from said second center portion and surrounding said fourth inlet trough, wherein said first and second configurations are differently shaped from one another; a pair of first plates disposed in a back to back mirrored relationship to one another with said peripheral lips thereof engaging one another and said first mounds thereof engaging one another, whereby said return apertures, said inlet apertures and said outlet apertures thereof are aligned; a pair of second plates disposed in a back to back mirrored relationship to one another with said peripheral lips thereof engaging one another and said second and third mounds thereof engaging one another, whereby said return apertures, said inlet apertures and said outlet apertures thereof are aligned; and said pairs being alternatingly stacked with respect to one another with said first and second return troughs engaging one another whereby said return apertures are aligned to define a return tank, said inlet troughs engaging one another whereby said inlet apertures are aligned to define a first and second inlet manifolds, and said outlet troughs engaging one another whereby said outlet apertures are aligned to define an outlet manifold, and whereby said center portions of said pair of first plates are spaced apart to define a fluid pathway communicating with the return tank and the first and second inlet manifolds and said center portions of said pair of second plates are spaced apart to define a fluid pathway communicating with the return tank and the outlet manifold.
