Problems solved by technology

As a result, the arrangement density of the fins 1' in the heat exchanger is not uniform, and the shape cannot meet the design requirements
After welding the fin 1' and the flat tube 2', the shape of the area A' enclosed by the two adjacent straight sections 11' of the fin 1' and the flat tube 2' is irregular and inconsistent, so the The heat transfer coefficient is reduced, resulting in a decrease in the performance of the heat exchanger, and the heat exchanger looks uneven and poor in appearance

Abstract

The invention provides a fin of a heat exchanger which comprises a straight section, an arc section and an arc transitional section which is connected between the straight section and the arc section. R is greater than r, wherein, R is the semidiameter of the arc section, and r is the semidiameter of the arc transitional section. When the fin is assembled and welded at the heat exchanger, the fin has regular and easily controllable transformation, uniform arrangement density, the high stability of shape and large heat transfer coefficient. The invention also provides a heat exchanger with the fin and a heat exchanger device consisting of a plurality of heat exchangers.

Description

technical field [0001] The invention relates to a fin, a heat exchanger with the fin and a heat exchanger device, in particular to a corrugated fin, a microchannel heat exchanger with the fin, and a heat exchanger composed of a plurality of microchannels. A heat exchanger device composed of heat exchangers. Background technique [0002] In traditional heat exchangers, corrugated fins have been widely used. Traditional corrugated fins consist of a straight section and a rounded root. In the process of manufacturing the heat exchanger, the fins 1' are arranged horizontally or vertically between the flat tubes 2' of the microchannel heat exchanger; during assembly, the fins 1' are pressed against the heat exchanger Between the tubes 2', the fins 1' are deformed, usually at the root of the arc and / or at the connection between the root of the arc and the straight part, wherein Figure 10 shows the state before the deformation of the fin 1', Figure 11 The state after deformati...
