ABSTRACT:
A fin comb for combing, straightening and cleaning fins of heat exchangers, such as fin-type condensers and evaporators used in refrigeration and air conditioning systems. The fin comb comprises a handle and a plurality of fin combing heads which are interchangeably mounted on the handle. The fin combing heads are provided with fin-shaped teeth of different thickness and spacing for engaging heat exchanger fins of different thickness and spacing. The fin combing heads are also reversible on the handle to adapt the fin comb to both pulling and pushing strokes relative to the heat exchanger fins. The fin combing heads are color coded for easy selection of the right size for the various heat exchanger fin assemblies which are normally encountered by refrigeration and air conditioning servicemen.
