Fin rapid winding and welding-free air conditioner watch cooling coil

Abstract

The invention provides a technical scheme of a fin rapid winding and a welding-free air conditioner watch cooling coil. The watch cooling coil comprises the following steps: an aluminum fin is winded on at the set position with an infinite copper pipe on a reeling mascerating machine, a copper pipe is fed straightly without being rotated, an aluminium sheet is synchronously rotated on a revolving head and a clamping device, thereby leading the aluminum sheet to roll the copper pipe; a radiating pipe provided with an aluminum fin winded according to the design is bent, a reserved elbow position without fins is put into a pipe bender to be manufactured into a U-shaped elbow on the radiating pipe with the winded aluminum fin, and a bent elbow replaces a welded elbow; and the radiating pipe of each aluminum fin can not achieve a parallel arrangement, the radiating pipe of each aluminum fin has a certain downstream slope so as to manufacture a racking pipe radiator without the welded elbow, and supports at two ends are used for piling up at least one to multiple rack pipe radiators to form the whole watch cooling coil.

Description

Technical field: [0001] The invention relates to an air conditioner, in particular to a surface cooler for an air conditioner with fins that are wound and weld-free. Background technique: [0002] In the prior art, the known air conditioner heat exchanger (surface cooler) is a utility model patent of <Surface Cooler with Antifreeze Waterway Structure> announced by the State Intellectual Property Office, patent number 200420015978, the surface cooling of this patented technology It includes aluminum foil fins, straight pipes fixedly installed in the holes of the aluminum foil fins, connecting elbows at both ends of the straight pipes, water inlets and water outlets. The connecting elbow at the end connects several adjacent straight pipes with a difference in level to form a multi-circuit stroke waterway in a way that the water inlet to the water outlet becomes higher step by step. It forms a serpentine waterway design with the connecting elbow. When the running air is ...

[0002] In the prior art, the known air conditioner heat exchanger (surface cooler) is a utility model patent of announced by the State Intellectual Property Office, patent number 200420015978, the surface cooling of this patented technology It includes aluminum foil fins, straight pipes fixedly installed in the holes of the aluminum foil fins, connecting elbows at both ends of the straight pipes, water inlets and water outlets. The connecting elbow at the end connects several adjacent straight pipes with a difference in level to form a multi-circuit stroke waterway in a way that the water inlet to the water outlet becomes higher step by step. It forms a serpentine waterway design with the connecting elbow. When the running air is turned on, the water in the surface cooler can be effectively discharged, which can effectively prevent the freezing of the surface cooler caused by the inability to completely discharge the accumulated water. However: because Both ends of each straight pipe must be connected by elbow welding, such as 5 72 pipes, there must be 144 welding points, there is a hidden danger of leakage at the welding points, welding the elbows at the end is labor-intensive, the production efficiency is low, and the residual flux is harmful to the Harmful to human health, the residual flux in the pipe pollutes the water quality, which is the deficiency of the existing technology
