Abstract

The invention discloses a manufacture device and method of a workpiece tube and a groove on the inner wall of the tube. The manufacture device of the groove on the inner wall of the tube comprises a positioning base (5) used for positioning the workpiece tube (4) connected with the anode of power supply equipment; a radial telescopic device can extend into the workpiece tube (4), the radial telescopic device is provided with multiple moving blocks (3) moving in the radial direction of the radial telescopic device, and a gap containing an electrolyte solution is formed between the inner wall of the workpiece tube (4) and the outer surfaces of the moving blocks (3); bulge structures (7) are arranged on the outer surfaces of the moving blocks (3), and the outer surfaces of the bulge structures (7) are electrode surfaces (12) used for being connected with the cathode of the power supply equipment. According to the manufacture device of the groove on the inner wall of the tube, manufacture is easy and convenient, and the heat exchange efficiency of the workpiece tube is improved.

Description

technical field [0001] The invention relates to the technical field of pipe fitting processing equipment, in particular to a workpiece pipe, a pipe inner wall groove processing device and a method thereof. Background technique [0002] With the rapid development of the economy, the market capacity of air conditioners is expanding year by year, and the quality requirements for air conditioners are also gradually increasing. In the air-conditioning and refrigeration industry, with the development of air-conditioning equipment in the direction of large capacity, low energy consumption and miniaturization, the demand for heat exchange of heat exchange tubes also increases. [0003] In order to improve the heat exchange efficiency of the heat exchanger (evaporator and condenser) in the air conditioner, the heat exchanger is generally processed from a workpiece tube (such as a copper tube) with grooves on the inner wall of the tube. [0004] At present, there are mainly two metho...
