Spiral heat exchanger and manufacturing method thereof and air conditioner

Abstract

The invention provides a spiral heat exchanger and a manufacturing method thereof and an air conditioner. The spiral heat exchanger comprises a heat exchange pipe and a plurality of fins, the heat exchange pipe is spirally wound to be cylindrical, the centers of the fins are provided with mounting holes matched with the heat exchange pipe, and the outer portion of the heat exchange pipe is sleeved with the fins at intervals through the mounting holes. Air can be sucked around the spiral heat exchanger; compared with a mode that a traditional plane-shaped heat exchanger can only suck air with one side, the windward area of the spiral heat exchanger is increased by 2-3 times, and integral heat exchange efficiency of the spiral heat exchanger is greatly improved; in addition, according to the spiral heat exchanger, a semicircular connecting pipe does not need to be welded to the heat exchange pipe, the bending process and cost of the semicircular pipe are reduced, the technical risk of refrigerant leakage caused by poor pipe opening welding is avoided, the manufacturing of the spiral heat exchanger becomes simple and convenient, product quality is effectively guaranteed, and product production efficiency is improved.

Description

technical field [0001] The present invention relates to the field of household appliances, more specifically, to a spiral heat exchanger, a manufacturing method of the spiral heat exchanger and an air conditioner. Background technique [0002] The heat exchangers used in existing household air conditioners are generally tube-fin heat exchangers, and most of them are planar heat exchangers. The problem of poor efficiency, in the current environment where the global awareness of energy conservation is gradually increasing, the energy efficiency of air-conditioning products is improving year by year, however, if figure 1 As shown, the traditional structure of the existing planar tube-fin heat exchanger 100' limits the heat exchange level of the heat exchanger 100', and each of the existing planar tube-fin heat exchanger 100' The nozzles of the heat exchange tubes 10' must be welded with connecting pipes such as the semicircular pipes 20', which is not conducive to production a...

Problems solved by technology

[0002] The heat exchangers used in existing household air conditioners are generally tube-fin heat exchangers, and most of them are planar heat exchangers. This structural form of heat exchanger has small windward area, multi-row heat exchange The problem of poor efficiency, in the current environment where the global awareness of energy conservation is gradually increasing, the energy efficiency of air-conditioning products is increasing year by year, however, if figure 1 As shown, the traditional structure of the existing planar tube-fin heat exchanger 100' limits the heat exchange level of the heat exchanger 100', and each of the existing planar tube-fin heat exchanger 100' The nozzle of the heat exchange tube 10' must be welded with connecting pipes such as the semicircular pipe 20', which is not conducive to production automation, and is prone to technical risks of refrigerant leakage due to poor welding of the nozzle
