Abstract

The invention discloses an air-conditioning heat exchanger, which includes heat dissipation fins, a diverter tube, a header tube and several heat exchange tubes. The tube wall of the diverter tube is provided with a diverter hole that communicates with the heat exchange tubes. The tube wall of the header tube is provided with a header hole connected to the heat exchange tube. The heat exchange tube penetrates the heat dissipation fins. Both ends of the heat exchange tube are connected to the shunt tube and the heat exchanger tube respectively. As for the header pipe, the inner cross-sectional area of ​​the heat exchange tube is larger than the area of ​​the diverter hole. Provide an air conditioning heat exchanger that uses small diameter copper tubes, has a simple and practical overall structure, and has excellent heat exchange effects, reducing product material costs by 10-35% and increasing heat exchange efficiency by 5%.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment, and more specifically relates to a small-diameter tube-fin air-conditioning heat exchanger. Background technique [0002] At present, the heat exchangers for air conditioners are mainly tube-fin type, and the pipe materials are mainly copper pipes. Copper is expensive, how to consume less material cost, improve the energy efficiency ratio of air conditioners; promote my country's energy conservation awareness, save material consumption to improve the production cost and market competitiveness of air conditioners, etc., are becoming more and more prominent. In recent years, the price of copper materials has continued to rise, making the cost of U-shaped copper tubes used in air-conditioning condensers increase from 85% to 95% of the total cost of the condenser. The key to reducing costs. [0003] In known prior art, the used condenser structure of air conditioner is as figure...
