[0002] At present, a special processing equipment for processing semicircular arc heat-absorbing fins is disclosed. The special processing equipment for semicircular arc heat-absorbing fins of solar collectors is composed of a pressing roller arranged on a frame, and is used for processing solar collectors composed of heat collecting tubes and fins. The special processing equipment is composed of a pair of pressing rollers that cooperate with each other, and the upper pressing roller is provided with a pressing groove with a semicircular cross-section concave inward, and the diameter of the pressing groove is equal to the sum of the outer diameter of the heat collecting tube and the thickness of the fin. The lower pressing roller is provided with a supporting groove with a semicircular cross-section concave inward, and the diameter of the supporting groove is equal to the diameter of the heat collecting tube. The pair of pressing rollers rotate at the same linear speed driven by a motor, and the equipment can press the semicircular arc shape that fits tightly with the outer side of the heat collecting tube, thereby increasing the heat exchange area between the fin and the heat collecting tube.
