An evaporator fabricated from a plurality of plates arranged in spaced parallel relation with one another within a housing or casing having inlet and outlet openings. The plates are arranged to define fluid passages for both water and refrigerant with the refrigerant passages having separators positioned therein. The housing is provided with partitions that cooperate with certain of said plates to define water passages which extend in a serpentine manner from the inlet to the outlet, with the inlet communicating with the greater number of water passages that gradually diminish in number from the inlet to the outlet.

An evaporator comprising a casing having a plurality of plates arranged in pairs in vertical planes and in spaced parallel relation to one another, each pair of plates defining a passageway and each pair of plates defining a passage between adjacent pairs of plates for the passage of water, a refrigerant consisting of a boiling fluid at a constant temperature flowing through said passageways in a crossflow path to said passages, said casing having inlet and outlet water openings therein defined by internal abutments, said abutments engaging certain of said plates and forming a sinuous path for the water moving through said passages from said inlet to said outlet with the initial series of water passages being greater in number than the next series which is in turn greater in number than the next series that communicates with the outlet opening.
