Have a plurality of condensing units in the described condensation segment, during refrigerating state, at least have No. two inlet tubes in described each condensing unit, flow of refrigerant route in described each road is, row U type pipe during row U type Guan Houzai flows in flowing through earlier, cold-producing medium is therefrom arranged U type pipe and is flowed out the back and accumulate one the tunnel by two-way at least and enter and efflux U type pipe, and cold-producing medium is flowed through and effluxed the laggard inlet/outlet pipe of U type pipe.When heating state, the route of flowing through of cold-producing medium is by reverse path flows.
The multichannel outlet of described a plurality of condensing units comes together in liquid separatnig valve, and described liquid separatnig valve outlet connects a way outlet pipe, is connected with electric expansion valve on described outlet.
The outlet of described liquid separatnig valve outlet is communicated in the U type pipe in the described super cooled sect, and the terminal U type pipe in the super cooled sect is communicated in and always goes out pipe.
Described fin adopts wide hydrophilic aluminium foil.
Described U type pipe adopts Φ 7 inner screw thread copper pipes.
U type pipe in the described super cooled sect is two row U type pipes, or three row U type pipes.
The utility model adopts fin-tube type heat exchanger, in order to improve the exchange capability of heat of heat exchanger, carries out design concept from following several respects: (1) improves the coefficient of heat transfer; (2) increase heat exchange area; (3) mean temperature difference of increase air side and refrigerant side.This fin-tube type heat exchanger according to wind field situation optimal design pipeline flow process, improves super cooled sect and distributes, thereby improve exchange capability of heat and Energy Efficiency Ratio by changing copper pipe quantity.
The utility model compared with prior art has the following advantages and good effect:
1, owing to adopts three row U type pipes, each road cold-producing medium of condensing unit flow through route for → interior row → middle row → two-way be combined into one the tunnel → efflux, interior row and the full and uniform heat exchange of middle row, and made full use of and effluxed exchange capability of heat, every road heat exchange effect is even, by changing the heat exchanger structure flow process, improve heat exchanger exchange capability of heat and Energy Efficiency Ratio, and improved the performance of air conditioner.
2, this heat exchanger adopts 13.6 wide hydrophilic single bridge fins of three rows, Φ 7 efficient inner screw thread copper pipes, the structure high-efficiency compact, characteristics according to the air-conditioner outdoor unit double fan, analyze wind field optimal design heat exchanger flow process, improve the super cooled sect structure and prevent that condenser bottom frosting seriously causes system's defrost bad under the low temperature, can under cooling condition, reduce condensation temperature, improve the air-conditioning Energy Efficiency Ratio, it is even to heat under the condition separatory, delays frosting, and thoroughly defrost.
