Detailed description of the invention
Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
As it is shown in figure 1, according to the heat exchanger tube of the present invention, including: at least one flow-disturbing section 1；Turbulence structure 10, is arranged at every
In the refrigerant circulation passage of flow-disturbing section 1 described in.According to the heat exchanger tube of the present invention, by arranging flow-disturbing section 1 on heat exchanger tube,
And turbulence structure 10 is set in the circulation passage of flow-disturbing section 1, the setting of turbulence structure 10 can upset the system flowing through flow-disturbing section 1
Cryogen, enhances the turbulent flow in circulation passage, and adds the velocity gradient in circulation passage so that cold-producing medium can be more fully
With the contact internal walls of heat exchanger tube, thus improve the coefficient of heat transfer of heat exchanger tube, improve heat exchanger tube, heat exchanger and air conditioning unit heat exchange
Performance.
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, the cold-producing medium of the most non-flow-disturbing section 2 flows into flow-disturbing section 1, flows into non-flow-disturbing section 2 again, then after flow-disturbing section 1 flow-disturbing
Flow into flow-disturbing section 1 again.During cold-producing medium flows through flow-disturbing section 1, due to obstructing of turbulence structure 10, on the one hand make circulating face
Long-pending reducing, the original type of flow of cold-producing medium is broken suddenly, and flow velocity increases；On the other hand formed in turbulence structure 10 downstream
Negative pressuren zone, cold-producing medium converge during formed turbulent flow, increase the velocity gradient of cold-producing medium, cold-producing medium more fully with change
The contact internal walls of heat pipe.
As illustrated in fig. 1 and 2, turbulence structure 10 includes spoiler 11 and for the supporting part being fixedly installed by spoiler 11
12.Under the obstructing of spoiler 11, the original type of flow of cold-producing medium can be broken, and the flow velocity of cold-producing medium increases.Preferably, disturb
The circulation passage of cold-producing medium is divided into multiple subchannel 13 by stream portion 11 and supporting part 12.It is flowed into flow-disturbing section 1 from non-flow-disturbing section 2
Cold-producing medium, is entered in multiple little subchannel 13 by overall circulation passage suddenly, will necessarily upset original type of flow；
And owing to the volume sum of multiple subchannels 13 is less than the volume of circulation passage, cold-producing medium flowing velocity in subchannel 13 adds
Hurry up, therefore spoiler 11 and supporting part 12 circulation passage of cold-producing medium is divided into multiple subchannel 13 will necessarily increase cold-producing medium with
The touch opportunity of the inwall of heat exchanger, thus 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
Between the internal perisporium of heat exchanger tube, this simple in construction, easy to assembly, and manufacturing cost is relatively low.Spoiler 11 and supporting part 12 can
Being one-body molded, it is also possible to split is arranged.More specifically, supporting part 12 includes that multiple gripper shoe, multiple gripper shoes uniformly set
Being placed between periphery wall and the internal perisporium of heat exchanger tube of spoiler 11, multiple gripper shoes are by the periphery wall of spoiler 11 and heat exchanger tube
Internal perisporium between circular passage be divided into multiple subchannel 13.Multiple gripper shoes are uniformly arranged on 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 cold-producing medium and heat exchanger tube
The probability of internal perisporium contact is essentially identical, is conducive to making all refrigerant heat exchanger uniform.As Fig. 2 is to shown in 5, in different enforcement
In example, two, three, four or five subchannels 13 that spoiler 11 is formed with supporting part 12.Spoiler 11 can be square
Or circular or other abnormity；One end of supporting part 12 is suitable with the structure of the internal perisporium of heat exchanger tube, and remainder is permissible
For arbitrary structures；Spoiler 11, supporting part 12 with the shape of cross section of the subchannel 13 of the internal perisporium formation of heat exchanger tube can be
Semicircle, sector, circular or other structures.
Preferably, turbulence structure 10 also includes being arranged on spoiler 11 periphery wall or on the internal perisporium of flow-disturbing section 1
Spoiler or flow-disturbing groove, by spoiler 11 and spoiler or the mating reaction of flow-disturbing groove, thus improve flow-disturbing effect further
Really, so improve heat exchange efficiency.It is highly preferred that spoiler or flow-disturbing groove curl extend, so that cold-producing medium is flowing over
Journey rotates, thus improves flow-disturbing effect further.
In another embodiment of the invention, turbulence structure 10 can also be for only arranging disturbing on the internal perisporium of flow-disturbing section 1
Flow or flow-disturbing groove, be equally reached and form the effect improving heat exchange efficiency.
In various embodiments of the present invention, turbulence structure 10 is prepared by heat-conducting, such as metal heat-conducting material, so that
Cold-producing medium is in addition to carrying out heat exchange with the internal perisporium of heat exchanger tube, it is also possible to carries out heat exchange with turbulence structure 10, increases heat-transfer surface
Long-pending, improve heat exchange efficiency.
Present invention also offers a kind of heat exchanger, this heat exchanger tube includes above-mentioned heat exchanger tube, to improve whole heat exchanger
Heat exchange efficiency.
Present invention also offers a kind of air conditioning unit, including above-mentioned heat exchanger, to improve the overall performance of air-conditioning.
As can be seen from the above description, the above embodiments of the present invention achieve following technique effect:
According to the heat exchanger tube of the present invention, by arranging flow-disturbing section 1 on heat exchanger tube, and in the circulation passage of flow-disturbing section 1
Arranging turbulence structure 10, the setting of turbulence structure 10 can be upset the cold-producing medium flowing through flow-disturbing section 1, enhance in circulation passage
Turbulent flow, and add the velocity gradient in circulation passage so that cold-producing medium can more fully with the contact internal walls of heat exchanger tube, thus
Improve the coefficient of heat transfer of heat exchanger tube, improve heat exchanger tube, heat exchanger and air conditioning unit heat exchange property.
These are only the preferred embodiments of the present invention, be not limited to the present invention, for those skilled in the art
For Yuan, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any amendment of being made,
Equivalent, improvement etc., should be included within the scope of the present invention.
