Beschreibung
Zusammenfassung:	A plate and tube heat exchanger assembly includes a plurality of coolant transporting tubes and a plurality of spaced plates to be periodically defrosted. The tubes pass through the plates and are in heat conducting relationship therewith at junction points with the plates. At least one but less than all of the plates may be modified, according to the instant invention, to include an electric heating element disposed at one end thereof for imparting heat through the plate and to the tubes and other plates at the junction points therebetween at predetermined times for periodic defrosting. The thickness of the plates having heating elements associated therewith are of a greater thickness than the remainder of the plates.
