Pipe fin single body, heat exchanger with pipe fin single bodies, and air conditioner

Abstract

The invention discloses a pipe fin single body, a heat exchanger with pipe fin single bodies, and an air conditioner. The pipe fin single body comprises a plurality of pipe fin bodies. Each pipe fin body comprises a body becoming a platy structure and at least one channel part which is arranged on the body and extends in the length direction of the body, wherein the channel part and the body are an integrally-formed piece, the thickness of the body is smaller than the thickness of the channel part, and a runner with the two ends opened is limited in the channel part. The multiple pipe fin bodies are sequentially connected in the body width direction. According to the pipe fin single body, each channel part and the corresponding body are set to be the integrally-formed piece, and the heat conduction efficiency between each channel part and the corresponding body is improved. Meanwhile, the multiple pipe fin bodies are sequentially connected in the body width direction, and actual application can be better achieved. When the pipe fin single bodies are applied to the heat exchanger, the heat exchange efficiency of the heat exchanger can be improved.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a tube-fin unit and a heat exchanger and an air conditioner having the same. Background technique [0002] In the related art, mass-produced heat exchangers include finned tube heat exchangers and microchannel heat exchangers, and the circular tubes of the finned tube heat exchangers or the flat tubes of the microchannel heat exchangers are arranged horizontally. . Moreover, in order to obtain the heat conduction area to the outside of the tube, the fins that expand the heat conduction area are arranged in a vertical direction. In addition, the tubes and fins are combined by expanding the tubes. [0003] However, due to the large pipe diameter and the horizontal arrangement, the condensed water is not discharged smoothly, and the pressure loss on the air side is large. Moreover, since the tubes and finned expansion tubes are combined, the contact thermal resistance betwe...
