AI Technical Summary
Technical Problem
The copper tubes used in existing air conditioners limit the lightweight and low cost requirements of the equipment due to their high weight and high cost.
Method used
The heat exchange tube is made of aluminum or aluminum alloy material, and the tooth structure is set on the inner wall of the tube body to optimize the ratio of the outer diameter and wall thickness of the tube body, as well as the tooth height and number of tooths to increase the contact area between the refrigerant and the heat exchange tube.
Benefits of technology
By using heat exchange pipes made of aluminum and tooth structures, the production cost and weight are reduced while maintaining high heat exchange efficiency, which is suitable for air conditioners that pursue lightweight and low-cost.

Abstract
The utility model provides a heat exchange tube, a heat exchanger with the heat exchange tube and an air conditioner with the heat exchange tube. The heat exchange tube is integrally formed by aluminum or aluminum alloy materials and comprises a tube body and teeth. The pipe body is in a pipe sleeve shape with equal wall thickness. The teeth are arranged on the inner wall of the pipe body in a protruding mode, extend in the pipe length direction of the pipe body and are evenly distributed in the circumferential direction of the pipe body at intervals. The outer diameter of the pipe body ranges from 5 mm to 7 mm, the ratio of the outer diameter of the pipe body to the wall thickness ranges from 10 to 15, and the ratio of the outer diameter of the pipe body to the tooth height of the teeth ranges from 25 to 35. The heat exchange tube is made of aluminum or aluminum alloy, so that the heat exchange tube is low in production cost and light in weight. By limiting the outer diameter size of the tube body, the ratio of the outer diameter of the tube body to the wall thickness and the ratio of the outer diameter of the tube body to the tooth height of the teeth, the contact area of a refrigerant and the heat exchange tube is increased, the heat exchange efficiency is improved, and the purpose of keeping good heat exchange performance under the condition that the weight and the cost of the heat exchange tube are reduced is achieved.
