Embodiment
Describe the utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in figure 1, according to heat exchanger tube of the present utility model, including：At least one flow-disturbing section 1；Turbulence structure 10, is set
In in the refrigerant circulation passage of each flow-disturbing section 1.According to heat exchanger tube of the present utility model, by being set on heat exchanger tube
Flow-disturbing section 1, and turbulence structure 10 is set in the circulation passage of flow-disturbing section 1, the setting of turbulence structure 10, which can be upset to flow through, disturbs
The refrigerant of section 1 is flowed, the turbulent flow in circulation passage is enhanced, and add the velocity gradient in circulation passage so that refrigerant
It can more fully be contacted with the inwall of heat exchanger tube, so as to improve the coefficient of heat transfer of heat exchanger tube, improve heat exchanger tube, heat exchanger and air-conditioning
The heat exchange property of unit.
Specifically, heat exchanger tube includes at least one flow-disturbing section 1 and at least one non-flow-disturbing section 2, flow-disturbing section 1 and non-flow-disturbing section
2 alternate settings, i.e., the refrigerant of non-flow-disturbing section 2 flows into flow-disturbing section 1, flows into non-flow-disturbing section 2 again after flow-disturbing 1 flow-disturbing of section, then
Flow-disturbing section 1 is flowed into again.During cold-producing medium stream is through flow-disturbing section 1, due to obstructing for turbulence structure 10, on the one hand cause circulating face
Product reduces, and the original type of flow of refrigerant is broken suddenly, flow velocity increase；On the other hand formed in the downstream of turbulence structure 10
Negative pressuren zone, refrigerant forms turbulent flow during convergence, increases the velocity gradient of refrigerant, refrigerant is more fully with changing
The inwall contact of heat pipe.
As illustrated in fig. 1 and 2, turbulence structure 10 includes spoiler 11 and the supporting part for spoiler 11 to be fixedly installed
12.Under the obstructing of spoiler 11, the original type of flow of refrigerant can be broken, the flow velocity increase of refrigerant.Preferably, disturb
The circulation passage of refrigerant is divided into multiple subchannels 13 by stream portion 11 and supporting part 12.Flow-disturbing section 1 is flowed into from non-flow-disturbing section 2
Refrigerant, is entered in multiple small subchannels 13 by overall circulation passage, will necessarily upset original type of flow suddenly；
And because the volume sum of multiple subchannels 13 is less than the volume of circulation passage, flowing velocity of the refrigerant in subchannel 13 adds
Hurry up, thus spoiler 11 and supporting part 12 by the circulation passage of refrigerant be divided into multiple subchannels 13 will necessarily increase refrigerant with
The touch opportunity of the inwall of heat exchanger, so as to improve heat exchange efficiency.
Specifically, spoiler 11 is arranged at the center of circulation passage, supporting part 12 be arranged at the periphery wall of spoiler 11 with
It is this simple in construction, easy to assembly between the internal perisporium of heat exchanger tube, and manufacturing cost is relatively low.Spoiler 11 can with supporting part 12
, can also split setting to be to be integrally formed.More specifically, supporting part 12 includes multiple supporting plates, multiple supporting plates are uniformly set
It is placed between the periphery wall of spoiler 11 and the internal perisporium of heat exchanger tube, multiple supporting plates are by the periphery wall and heat exchanger tube of spoiler 11
Internal perisporium between circular passage be divided into multiple subchannels 13.Multiple supporting plates are uniformly arranged on to the periphery of spoiler 11
Between wall and the internal perisporium of heat exchanger tube, the volume of multiple subchannels 13 of formation is identical, so that refrigerant and heat exchanger tube
The probability of internal perisporium contact is essentially identical, is conducive to making all refrigerant heat exchangers uniform.As shown in Fig. 2 to 5, in different implementation
In example, spoiler 11 and two, three, four or five subchannels 13 of the formation of supporting part 12.Spoiler 11 can be square
Or circular or other abnormity；One end of supporting part 12 is adapted with the structure of the internal perisporium of heat exchanger tube, and remainder can be with
For arbitrary structures；The shape of cross section of the subchannel 13 of the internal perisporium formation of spoiler 11, supporting part 12 and heat exchanger tube can be
Semicircle, fan-shaped, circular or other structures.
Preferably, turbulence structure 10 also includes being arranged on the periphery wall of spoiler 11 on the either internal perisporium of flow-disturbing section 1
Spoiler or flow-disturbing groove, by the mating reaction of spoiler 11 and spoiler or flow-disturbing groove, so as to further improve flow-disturbing effect
Really, so improve heat exchange efficiency.It is highly preferred that spoiler or the extension of flow-disturbing groove curl, so that refrigerant is being flowed over
Rotated in journey, so as to further improve flow-disturbing effect.
In another embodiment of the present utility model, on the internal perisporium that turbulence structure 10 can also be only to set flow-disturbing section 1
Spoiler or flow-disturbing groove, be equally reached to be formed improve heat exchange efficiency effect.
In each embodiment of the present utility model, turbulence structure 10 is prepared by heat-conducting, such as metal heat-conducting material, with
So that refrigerant is in addition to the internal perisporium with heat exchanger tube is exchanged heat, it can also be exchanged heat with turbulence structure 10, increase and change
Hot area, improves heat exchange efficiency.
The utility model additionally provides a kind of heat exchanger, and the heat exchanger tube includes above-mentioned heat exchanger tube, to improve whole heat exchange
The heat exchange efficiency of device.
The utility model additionally provides a kind of air-conditioner set, including above-mentioned heat exchanger, to improve the overall performance of air-conditioning.
As can be seen from the above description, the utility model the above embodiments realize following technique effect：
According to heat exchanger tube of the present utility model, lead to by setting flow-disturbing section 1 on heat exchanger tube, and in the circulation of flow-disturbing section 1
Turbulence structure 10 is set in road, and the setting of turbulence structure 10 can upset the refrigerant for flowing through flow-disturbing section 1, enhance circulation passage
Interior turbulent flow, and add the velocity gradient in circulation passage so that refrigerant can be contacted more fully with the inwall of heat exchanger tube,
So as to improve the coefficient of heat transfer of heat exchanger tube, the heat exchange property of heat exchanger tube, heat exchanger and air-conditioner set is improved.
Preferred embodiment of the present utility model is these are only, the utility model is not limited to, for this area
