Indoor air conditioner and fin production method

Abstract

The invention discloses an indoor air conditioner and a fin production method. The indoor air conditioner is internally provided with a heat exchanger, and the heat exchanger comprises a plurality ofheat exchange tubes and a heat dissipation device. The heat dissipation device comprises a plurality of parallel fins, in the fin production process, fin machining adopts a beveling machining method,and the beveling machining method comprises the two procedures of pre-punching and beveling. According to the indoor air conditioner and the fin production method, the fins are cut through one set ofcutters, the problem that an existing beveling process cannot meet the requirement for the pipe hole cutting safety distance is solved, and the problems that two sets of cutters are adopted for special-shaped cutting, the process is complex and the cost is high are also solved.

Description

technical field [0001] The invention relates to the technical field of air conditioner design and production, in particular to an indoor air conditioner and a fin production method. Background technique [0002] In the current commercial air-conditioning duct machine, in order to meet the compactness requirements of the product, the heat exchanger is often equipped with multiple rows of copper tubes and the same number of fins, among which 3 rows of copper tubes and 3 rows of fins are the most common. In the production process of multi-column fins, the punching machine cuts the continuous aluminum foil at a specific length. According to the design requirements, the cutting surface of the aluminum foil is mainly horizontal and oblique. [0003] Among them, there is a fit gap between the heat exchanger and the air duct unit frame produced by the cross-cutting process, the uniformity of the wind field is poor, the installation space of the heat exchanger in the frame is not ful...

Problems solved by technology

[0007] In some embodiments of the present application, in order to solve the above technical problems, a method for producing indoor air conditioners and fins is provided. The fins are produced and cut in the form of special-shaped oblique cutting, and the fin production process mainly includes pre-punching and oblique cutting. Two processes, the pre-punching hole is formed by pre-punching the fin wall, and the pre-punching hole is used to cut twice. The cutting process uses a set of cutting tools, which solves the problem that the above-mentioned oblique cutting process cannot meet the safety distance of tube hole cutting , and the above-mentioned heterosexual cutting uses two sets of knives, the process is complicated and the cost is high
