According to the flat tube, the micro-channel heat exchanger and the air conditioner, the water guide groove extending along the length direction of the flat tube is arranged outside the flat tube, so that condensed water can be more easily gathered in the water pouring groove under the action of air flow and gravity, and the condensed water can be more effectively discharged.
Description
Technical field
The present invention relates to field of air conditioning, in particular to a kind of flat tube, micro-channel heat exchanger and air-conditioning.
Background technology
Micro-channel heat exchanger with the advantage on its efficient heat exchange property, compact structure and cost, in business, domestic system
The application of cold air conditioner industry has broad prospects, but exists very if using according to the arrangement of traditional air conditioner heat exchanger
Many problems, wherein condensation and frosting are two maximum difficult points, and when using especially as outer machine condenser, problem is more prominent.
Found by analysis, when being disposed vertically, no matter flat tube is vertical or level, and the condensed water of generation all will
It is blocked it is impossible to smoothly flow down.When flat tube is vertically placed, condensed water will be blocked by fin, cold when flat tube horizontal positioned
Solidifying water will be blocked by flat tube itself.Correlational study shows for the pipe wing heat exchanger being equally disposed vertically and Thermal Performance of Micro Channels
Device, the condensate of pipe wing heat exchanger 80% can be excluded within the time of 1s, and micro-channel heat exchanger then needs the time of nearly 10s.
Additionally, microchannel is after soldering, certain brazing flux is remained on its aluminum pipe and fin, forms uneven coarse surface,
On the one hand it is to provide condensation nuclei when heat exchanger wall humid air condenses, on the other hand also increase the difficulty of condensate exclusion
Degree.The condensate being deposited in heat exchanger surface defines very big heat transfer resistance, governs the performance of heat exchanger heat-transfer performance.With
When, just because of micro-channel heat exchanger impeded drainage and surfaces versus rough, the membranaceous or pearl water droplet of remained on surface defines
Core needed for frosting is so that micro-channel heat exchanger is more easy to frosting.Correlation test research it is also shown that when ability is identical, microchannel
Heat exchanger is easier frosting compared with copper pipe aluminum fin heat exchanger, in frosting first, when that is, heat exchanger surface is also relatively dried, its knot
White speed is 1.25 times of common copper pipe aluminum fin heat exchanger；And the reason due to impeded drainage, micro-channel heat exchanger is in process
After repeatedly knot (change) is white, its average frosting velocity will faster than frosting first 70% about, simultaneously will be with copper pipe aluminum fin heat exchanger
Frosting velocity margi n pulls big under square one is to 1.78 times, and micro-channel heat exchanger defrost required time is compared with copper pipe aluminum fin
Heat exchanger length 40% about.Micro-channel heat exchanger is low compared with copper pipe aluminum fin heat exchanger by 22% in the average ability of frosting defrosting cycle
Left and right, eer is low by 13%.
How to contain the quick frosting of micro-channel heat exchanger, reduce the frequency of its defrosting and shorten defrosting time, be to improve
Its performance and promote its extensively application institute must solution a great problem.
Content of the invention
The present invention is intended to provide a kind of flat tube, micro-channel heat exchanger and air-conditioning that can effectively exclude condensed water.
The invention provides a kind of flat tube, there are inside flat tube heat exchanger channels, the outside of flat tube has along flat tube length side
To the guiding gutter extending.
Further, guiding gutter is arranged on the flat horizontal surface of the both sides of flat tube, and at least sets respectively on the flat horizontal surface of both sides
Put a guiding gutter.
Further, along the airflow direction on flat tube surface, guiding gutter is arranged on the air side of flat tube.
Further, along the airflow direction on flat tube surface, the air side of flat tube is provided with diversion division.
Present invention also offers a kind of micro-channel heat exchanger, the heat exchange fin be connected including aforesaid flat tube and with flat tube,
And flat tube is vertically arranged.
Further, heat exchange fin is horizontally disposed or is in tilted layout.
Further, along the airflow direction on flat tube surface, the width of heat exchange fin is less than the position of guiding gutter.
Further, when two or more guiding gutter is provided with the flat horizontal surface of flat tube, heat exchange fin is provided with and leads
The corresponding avoiding structure of tank.
Present invention also offers a kind of air-conditioning, including aforesaid micro-channel heat exchanger.
According to the flat tube of the present invention, micro-channel heat exchanger and air-conditioning, by the outside setting in flat tube along flat tube length side
To the guiding gutter extending, condensed water in the presence of air-flow and gravity, can more easily converge in surge tank such that it is able to
More effectively discharge condensed water.
