For solving the problems of the technologies described above, technical solution adopted in the utility model is a kind of multi-connected air conditioner heat exchanger, comprise U-shaped copper pipe and fin, its U-shaped copper pipe is arranged in parallel within the fin, and the arrival end of U-shaped copper pipe connects current divider and electric expansion valve, and the port of export of U-shaped copper pipe connects discharge.
Above-mentioned a kind of multi-connected air conditioner heat exchanger, its U-shaped copper pipe are the following U-shaped inner screw thread copper pipe of external diameter 5mm.
Above-mentioned a kind of multi-connected air conditioner heat exchanger, its U-shaped copper pipe is arranged in parallel within the fin more than three or three.
Above-mentioned a kind of multi-connected air conditioner heat exchanger, the distance between its U-shaped copper pipe is 8～25mm.
Adopt the shunting capillary to shunt in the above-mentioned a kind of multi-connected air conditioner heat exchanger, its current divider, shunting capillary external diameter is 3～5mm, and wall thickness is 0.5～1.5mm, and pipe range is 150～400mm.
Above-mentioned a kind of multi-connected air conditioner heat exchanger, its shunting capillary front end arranges electric expansion valve.
Above-mentioned a kind of multi-connected air conditioner heat exchanger arranges the tap hole more than 3 or 3 on its discharge, and is connected with the U-shaped copper pipe by gas-collecting branch pipe.
The utlity model has following advantage and useful technique effect:
1, the following alternative existing external diameter of U-shaped copper pipe of the utility model employing external diameter 5mm is 7mm and above U-shaped copper pipe, has both guaranteed original performance in air-conditioner uses, and saves simultaneously the consumption of copper pipe, energy-conserving and environment-protective.
2, the utility model U-shaped copper pipe cooperates electric expansion valve to carry out throttling in conjunction with the version that is arranged in parallel simultaneously, and such improvement can effectively reduce production costs for the heat exchanger that multi-connected machine adopts, and the range of decrease can reach more than 10%.
3, the utility model effectively reduces internal volume by the reasonably optimizing of heat exchanger structure, and the interior volume specific ratio of indoor set and off-premises station is mated more, is conducive to the performance of the stable and regulating power of whole system.
