Abstract:
An evaporator for a refrigeration system for reducing the temperature of a medium therein, said evaporator comprising:a first tube having an interior surface composed of a first material having a first thermal conductivity;a medium inlet and outlet associated with said first tube;a body composed of a second material circumscribing said first tube and disposed in intimate contact along at least a portion of said first tube, said second material having a greater thermal conductivity than the thermal conductivity of said first material;an evaporator refrigerant inlet and an evaporator refrigerant outlet in said body;a confined refrigerant path intermediate said inlet and outlet, and a plurality of fins in said path thereby increasing the surface area of the second material in the confined path.
