Strip fin and tube heat exchanger

Abstract

A strip fin sheet and tube heat exchanger formed by lancing a series of parallel rows of strip fin separated by a series of interconnecting unlanced strips which are connected in a heat transferring relationship to an outer surface of a tubular member for feeding a working fluid therethrough. The heat exchanger is generally of a plane form with the length of lanced fin strips being parallel to the plane while the width of lanced fin strips are twisted to an acute angle generally perpendicular to the plane of the sheets forming the assembly, thus forming a path for desired air to be forced to flow therethrough in a direction perpendicular to the plane of the sheets and parallel to the strip width or depth. The heat exchanger is intended for use in a forced draft application such as used in an air conditioner or refrigerator evaporator or condenser.
