Abstract
An eutectic beam which includes a plastic housing, an eutectic solution in the housing, and an evaporator tube in the eutectic solution having ends which extend outside the housing. The ends of the evaporator tube are adapted for connection to a refrigeration system. The evaporator tube is formed of copper having a thin protective coating on its outer surface formed of plastic, which is preferably a two component, filled epoxy resin system. The housing, in a preferred embodiment, is formed of a plastic, such as polyethylene, filled with a filler material selected to increase the thermal conductivity and thus the efficiency of the eutectic beam. In still another preferred embodiment, the filler material is also selected to increase both the electrical and thermal conductivity of the housing, with the housing including electrodes for electrically heating the housing to remove frost and ice build-up.
