Embodiment 1

[0012] Embodiment 1, a production method of a heat exchanger, including the following steps: Step A): using a hairpin pipe bender to remove copper through the process of loading-feeding straightening-cutting-bending-returning-collecting The tube is bent into a long U tube that meets the requirements. The length of the two straight tubes of the produced long U tube should be equal, and the U-shaped joint should be smooth without obvious folds and creases. Step B): Use a punch to stamp the aluminum foil into elongated fins, and the elongated fins are also stamped with several sets of through-hole groups, and the through-hole groups include several After the stamping is completed, a certain number of elongated fins are placed on the support rod through the through holes to form a group of tube fins to be pierced. Generally speaking, the length of the elongated fins should be matched with the tube expander in step D, preferably the length should be consistent with the feed port o...

Abstract

The invention relates to a method for producing heat exchangers and relates to a production method of the heat exchanger for an air conditioner. The method comprises ten steps from step A to step J and is mainly characterized in that an elongated fin is punched in step B, a plurality of through-hole groups are punched in the elongated fin, the arranging shape and the quantity of through holes of all the through-hole groups are consistent, and one heat exchanger can be individually formed by each through-hole group and a long U-shaped pipe. According to the method, a plurality of heat exchangers are combined together in the production process and are then separated out after the production process is finished. Compared with the prior art, according to the method, the production efficiency of the heat exchangers can be greatly improved, the labor load of workers is decreased, and the problems of low efficiency, labor consumption and time consumption when the heat exchangers are produced one by one in the past are solved.

Description

technical field [0001] The invention relates to a production method of a heat exchanger for an air conditioner. Background technique [0002] In traditional heat exchanger production, the size of the heat exchanger to be produced is first determined, and then the fins and heat exchange tubes that match it are produced, and finally assembled. But producing heat exchangers one by one is not only inefficient but also labor and time consuming. Due to the particularity of the structure of the heat exchanger for air conditioning, this kind of heat exchanger can first produce several fins shared by heat exchangers in the production process, and then install heat exchange tubes on the fins. After the product is cut, it can be turned into a heat exchanger that meets the requirements. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a heat exchanger production method, which can greatly increase the production efficiency...
