Problems solved by technology

[0004] For heat exchangers, the larger the temperature difference, the higher the heat transfer efficiency. Therefore, for multi-row heat exchangers, the heat transfer efficiency of the inner rows of heat exchangers is lower than that of the outer row heat exchangers. The heat exchange efficiency is not optimal in heat exchangers with the same pipe diameter

Embodiment Construction

[0016] See attached figure 1 , Double-row indoor heat exchangers are installed, 1 is the indoor unit of the air conditioner, 2 is the indoor fan, 3 is the heat exchanger of the indoor unit, 4 is a copper pipe with a large diameter, and 5 is a copper pipe with a small diameter.

[0017] Since the outermost part of the heat exchanger is copper tube 4 with a large diameter, and the distance between the copper tubes is small, when the air conditioner is in cooling operation, the low-temperature refrigerant in the copper tube cools the fins around the copper tube, Cooling is transferred to the air by heat exchange with the air. A row of copper tubes 5 with smaller tube diameters inside the heat exchanger, because the tube diameter becomes smaller and the tube spacing becomes larger, the temperature of the fins in the middle of the copper tubes is slightly higher than that of the fins between the copper tubes of the outermost row of heat exchangers. Temperature, since the temperatu...

Abstract

The invention discloses an air conditioner heat exchanger with mixed pipe diameters, which belongs to the technical filed of an air conditioner in electric appliance equipment. The air conditioner heat exchanger with mixed pipe diameters comprises a plurality of rows of heat exchange pipes, and the pipe diameter of the outer row of heat exchange pipes is larger than that of the inner row of heat exchange pipes. The invention adopts the air conditioner heat exchanger with mixed pipe diameters, ensures the uniform heat exchange, and thus improves the heat exchange efficiency. In addition, compared with the heat exchanger in the prior art, the invention has the advantages that the size of the heat exchanger can be smaller, so the material cost can be lowered.

Description

technical field [0001] The invention relates to the technical field of air conditioners in electrical equipment, and more specifically relates to an air conditioner heat exchanger with mixed pipe diameters. Background technique [0002] The heat exchange efficiency of the heat exchangers of the indoor and outdoor units of the air conditioner greatly affects the cooling performance and heating performance of the air conditioner. A high-efficiency heat exchanger can greatly reduce the volume of the heat exchanger, reduce the metal material of the heat exchanger, and thereby reduce the cost of the product. At present, φ9.52, φ7.94, φ7.0, φ6.0, φ5.05 copper tubes are most used in the heat exchangers of domestic air conditioners in my country, and the general heat exchangers use copper tubes of the same diameter. [0003] Almost all household air conditioners use air-cooled heat exchange, that is, the fan blows the heat exchanger of the indoor unit and the heat exchanger of the ...
