A laminate-type evaporator includes U-channel plates in combination with
various configurations of dual cup and single cup plates, to control
refrigerant pressure drop and achieve enhanced temperature spreads within
the evaporator. The U-channel plates define one or more of the final
refrigerant passes in the evaporator, and the dual cup and single cup
plates define refrigerant passes upstream therefrom. Fins are disposed
between adjacent plate pairs and extend to selected end edges of the
U-channel plates to maximize the surface area available for heat exchange
in the final refrigerant passes.
