Abstract

The invention relates to the technical field of heat exchange, in particular to a fin and a heat exchanger with same. The fin comprises a fin body, one end of the fin body is an upwind side, the end,opposite to the upwind side, of the fin body is a downwind side, the upwind side is provided with one or more flat tube grooves extending towards the downwind side, and the flat tube grooves are usedfor installing flat tubes; the fin body is provided with circulation bridge groups, the circulation bridge groups include a plurality of fin bridges and reinforcing structures, the reinforcing structures and the fin bridges are arranged alternatively, the circulation bridge groups are arranged on the fin body in a manner of being alternative with the flat tube grooves, and the circulation bridge group improves the structural strength of the fin; and meanwhile, the circulation bridge group accelerates air circulation, and the thermal efficiency of the heat exchanger is improved.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a fin and a heat exchanger having the same. Background technique [0002] The micro-channel heat exchanger is a new type of high-efficiency heat exchanger, which has the advantages of high heat transfer efficiency, small size, light weight, and less charge. The fins of the traditional single-cooling micro-channel heat exchanger are rolled by a rolling mill. into a wavy shape, and then brazed between the upper and lower flat tubes. [0003] Due to the small size and light weight of the fins, the structural strength of the fins is low and the heat exchange efficiency is low. Contents of the invention [0004] An object of the present invention is to provide a fin capable of improving the structural strength of the fin. [0005] Another object of the present invention is to provide a heat exchanger, which can increase the structural strength of heat exchange and improve he...
