Technical Field
The invention relates to the field of fins, in particular to a heat exchanger fin.
Background
The finned heat exchanger is one of the most widely used heat exchange devices in gas and liquid heat exchangers. The purpose of heat transfer enhancement is achieved by additionally arranging fins on a common base pipe. The base pipe can be a steel pipe; a stainless steel tube; copper tubing, and the like. The fins can also be made of steel belts; stainless steel belts, copper belts, aluminum belts, and the like. The fin type heat exchanger adopts mechanical winding fins, the contact surface of the radiating fins and the radiating pipe is large and tight, the heat transfer performance is good and stable, the air passing resistance is small, steam or hot water flows through the inside of the steel pipe, and heat is transferred to the air passing through the fins by the fins tightly wound on the steel pipe, so that the air heating and cooling effects are achieved.
To the inside heat exchanger fin that uses of water tank, because be welded fastening between traditional fin heat exchanger fin and the parent tube, if local fin is because of receiving the extrusion or striking to cause the back of buckling, the heat transfer effect will receive the influence to can only change whole heat exchange tube, cause the waste to the material.
