ABSTRACT:
A cross-fin coil type heat exchanger wherein a multiplicity of raised fins of the louver type are formed on the major portion of the surface of a convoluted fin base plate and the area of the portion of the fin base plate reduced in heat transfer performance is minimized, to improve the heat transfer effects achieved by the fins. Means is provided to inhibit the growth of a boundary layer by the front edge effect of the raised fins and promote the conversion of a current of a heat exchange fluid. Ribs are formed in the fins remote from heat transfer tubes to further promote the conversion of the current of the heat exchange fluid into a turbulent flow and also to reinforce the fins. The raised fins of the louver type have a construction that tends itself to good draining, to avoid an increase in the resistance offered to the passage of the current of the heat exchange fluid in wet condition.
