Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide an air conditioner heat exchanger with a smaller pipe diameter than the existing heat exchanger for the indoor box used by the current air conditioner. Reduce the amount of copper used in the air-conditioning indoor heat exchanger, save the material cost and processing cost of the heat exchanger, and reduce the consumption of copper resources

Abstract

The invention discloses an air-conditioning heat exchanger. The air-conditioning heat exchanger comprises a fin, a U-shaped pipe which passes through an inner cavity of the fin, a copper bridging bend which is fixed at the tail end of the U-shaped pipe, a liquid inlet pipe and an air outlet pipe which are connected with an outdoor unit, a distributor, an inlet branch pipe, an outlet summary flute-shaped pipe and an outlet branch pipe, wherein the inlet branch pipe comprises a first inlet branch pipe, a second inlet branch pipe and a third inlet branch pipe; and the outlet branch pipe comprises a first outlet branch pipe communicated with the first inlet branch pipe, a second outlet branch pipe communicated with the second inlet branch pipe, and a third outlet branch pipe communicated with the third inlet branch pipe. The air-conditioning heat exchanger keeps heat exchange quantity equivalent to that of the conventional phi7 pipe heat exchanger on the premise of reducing pipe diameter and saving pipes; and the cooling energy efficiency ratio (EER) and heating coefficient of performance (COP) of the whole machine are equal to those of the conventional machine.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, in particular to the technical field of heat exchangers for air conditioners. Background technique [0002] At present, the country advocates energy conservation and emission reduction to create a low-carbon society. Copper and aluminum are the main energy-consuming resources of household air conditioners, and the copper used in air conditioners accounts for a large proportion. As the price of copper rises, the cost of raw materials rises. Manufacturing costs increase accordingly. It will be an energy-saving project that benefits the country and the people for air-conditioning manufacturers to further reduce the amount of copper and aluminum used in air-conditioners through technical improvement. [0003] For most household split air conditioners at present, most of the indoor unit heat exchangers use copper tube fin heat exchangers with a diameter of Φ7, and this type of heat exchanger...
