Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model：
A kind of disturbed flow type double-tube heat exchanger as described in Figure 1, including outer tube 1, the inner tube 2 that is arranged in outer tube 1, inner tube 2
Inside be fixedly installed flow spoiler 3, outer tube 1, inner tube 2 are the straight tube being coaxially disposed, the both ends of outer tube 1 by necking welding with
Inner tube 2 links into an integrated entity.Refrigerant inlet 10,20 and outlet 11,21 are offered on outer tube 1, inner tube 2, specially respectively：Outer tube
1 refrigerant inlet 10 and outlet 11 are opened in the sides at two ends；The refrigerant inlet 20 of inner tube 2 and outlet 21 are opened in two ends
Portion.
When using：The cold-producing medium of outer tube 1 is entered 10 mouthfuls and is connected with the condenser of air-conditioning system, and the cold-producing medium of outer tube 1 goes out
Mouth 11 is connected with the interior machine of air-conditioning system so that forming the passage passing through for liquid refrigerant between outer tube 1 and inner tube 2；Interior
The refrigerant inlet 20 of pipe 2 is connected with the throttling arrangement of air-conditioning system, or the liquid being flowed out by the refrigerant outlet 11 of outer tube 1
A state cold-producing medium part enters the refrigerant inlet 20 of inner tube 2, the cold-producing medium of inner tube 1 after the throttling arrangement throttling through air-conditioning system
Outlet 21 is connected with the air intake duct of air-conditioning system so that inner tube 2 is internally formed the passage passing through for gaseous refrigerant.
During work：Condenser liquid refrigerant out is entered between 10 entrance inner and outer pipes 1,2 by the cold-producing medium of outer tube 1, with
Inner tube 2 carries out heat exchange, and by machine in refrigerant outlet 11 a part of liquid refrigerant arrival of outer tube 1, another part is through throttling
After device throttling, inner tube 2 is entered by the refrigerant inlet 20 of inner tube 2, after heat exchange, the refrigerant outlet 21 through inner tube 1 returns to suction
Tracheae.
In the present embodiment：
Outer tube 1 adopts 22.2mm standard copper pipe.
Inner tube 2 adopts 15.88mm high-efficiency fin pipe, and high-efficiency fin pipe adopts copper pipe through special cutting, is formed in the circumferential
Many is about the acupuncture of 5mm, compares same specification screwed pipe heat exchange area greatly, heat exchange amount can improve 15%-20%.
The cross section of flow spoiler 3 is consistent with the cross section of inner tube 2, and such as in the present embodiment, inner tube 2 is pipe, flow spoiler 3
Cross section be circle, and flow spoiler 3 edge be formed uniformly multiple allow the semicircular indentations 30 that pass through of cold-producing mediums, such as
Shown in Fig. 2.
Because inner tube 2 is straight tube, pipe interior air-flow is stable, and tube hub part gaseous refrigerant cannot get abundant heat exchange, heat exchange
Effect on driving birds is not good, leads to system degree of supercooling bad, and it is big to fluctuate, and therefore in order to overcome the problems referred to above, inner tube 2 is every its length 1/3
Position one flow spoiler 3 is set so that gaseous refrigerant helically rises inside pipe, flow regime is changed into rapid from laminar flow
Stream, improves the coefficient of heat transfer of metric system in heat exchanger tube, improves heat exchange efficiency；Additionally, this kind of spiralling air-flow strengthens to pipe
Washing away of inwall, can reduce attachment impurity and lubricating oil in pipe, be conducive to the steady in a long-term of systematic function, and improve returning of system
Oil.
Above-described embodiment is only that technology design of the present utility model and feature are described, its object is to allow and is familiar with technique
Personage will appreciate that content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.
All equivalence changes made according to the utility model Spirit Essence or modification, all should cover protection domain of the present utility model it
Interior.
