Background technology
The heat-exchanger rig that micro-channel heat exchanger is automobile, family expenses or commercial air conditioning system generally adopt, its evaporimeter that can act on air-conditioning system uses, and also can be used as condenser and uses.When using as evaporimeter, air is cooled when passing through the heat exchanger of low temperature, when temperature is reduced to dew-point temperature, can on the surface of heat exchanger, on the lateral surface of micro-channel flat He on fin, condensed water is formed on main, if condensed water can not get rid of effective eliminating in time, the phenomenon that condensate water is freezed may be there is, thus reduce heat exchanger heat exchange efficiency.When using as condenser, be usually placed in outdoor, rainwater or other sewage can be attached to the surface of heat exchanger, if rainwater or sewage can not be got rid of in time, will pollute thing and remain, thus reduce condenser corrosion resistance.Therefore, no matter use as evaporimeter, or use as condenser, all need in time the water on heat exchanger to be discharged.At present, drainage pattern micro-channel heat exchanger adopted has multiple.The patent No. is: ZL200580022765.4, and name is called: the patent of invention of evaporimeter discloses a kind of evaporimeter being beneficial to draining, sees accompanying drawing 8.The technical scheme that this patent realizes being beneficial to draining is that the leading edge of fin is protruded past forward described flat pipes of heat exchanger certain size.The principle that this structure effectively discharges condensed water is the surface tension utilizing outstanding fin, and heat exchanger drainage area is increased compared to the drainage area of the structure of not outstanding fin.Drainage increases, and is conducive to heat exchanger draining, thus improves heat exchange efficiency.This structure has the advantage being beneficial to draining, but also there is the deficiency of the following aspects:
1, the thickness of heat exchanger increases because of the increase of fin width, is unfavorable for the lightweight of heat exchanger.
2, fin larger, cost increases.
3, fin overhang in heat exchanger both sides will strictly control, and producting process difficulty increases.
4, flat tube given prominence to by fin, easily lodges, once the lodging of fin large area, affects heat exchange property, and in addition, heat exchanger presentation quality is difficult to ensure.
Summary of the invention
The utility model for solve in known technology the technical problem that exists and provide a kind of reduce producting process difficulty and cost, reduction heat exchanger thickness, be conducive to heat exchanger draining, thus ensure the micro-channel heat exchanger being beneficial to draining of heat exchange efficiency.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:
A kind of micro-channel heat exchanger being beneficial to draining, comprise collector tube, lower collector tube, be provided with between upper and lower collector tube and arrange micro-channel flat more, fin is provided with between adjacent micro-channel flat, the shell often arranging micro-channel flat parallels face by two and connects two ends formations of two parallel surfaces, it is characterized in that: each end of micro-channel flat is formed by face A and face B, the equilateral triangle shape forming convex or concave is intersected on two sides; The width of fin is consistent with the width of micro-channel flat.
The technical scheme that the utility model can also be taked is:
The end of micro-channel flat is evagination equilateral triangle shape, forms angle theta, 85 °≤θ≤105 ° between face A and face B.
The advantage that the utility model has and good effect are:
The end of micro-channel flat is set to the equilateral triangle of convex or concave by the utility model, this structure is compared to the end construction of existing circular arc, increase the drainage area between flat tube end and fin, thus heat exchanger Quick drainage can be ensured; The width of fin is consistent with the width of flat tube, compared to prior art, reduces production cost and producting process difficulty, also makes the thickness of heat exchanger reduce, thus is conducive to heat exchanger minimizing weight, namely realizes heat exchanger lightweight; Because fin does not exceed flat tube, it also avoid the problem of fin lodging, be easy to the presentation quality ensureing heat exchanger.

Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1-7, be beneficial to a micro-channel heat exchanger for draining, comprise collector tube 1, lower collector tube 2, between upper and lower collector tube, be provided with many row's micro-channel flat 3, be provided with fin 4 between adjacent micro-channel flat, in accompanying drawing, do not represent whole fin structure.Often arrange the shell of micro-channel flat by two limits paralleled and two the ends formations connecting two parallel edges.Each end 31 of micro-channel flat is formed by face A311 and face B312, and the equilateral triangle shape forming convex or concave is intersected on two sides.The end construction of evagination equilateral triangle shape is shown in Fig. 2-3, and the end construction of indent equilateral triangle shape is shown in Fig. 4-5.The width of fin is consistent with the width of micro-channel flat, i.e. the edge of fin and the end part aligning of micro-channel flat shell.
Consider from being easy to shaping technological angle, the end of micro-channel flat preferably adopts evagination equilateral triangle shape, forms angle theta between face A and face B.Drainage size is relevant with θ value.θ value is less, and drainage is larger, and draining is more favourable, but in the process of drainage increase, in flat tube, refrigerant circulation area is reducing thereupon, thus makes the degradation of heat exchange performance of heat exchanger.θ is excessive, helps the DeGrain of draining, and moisture can not be discharged smoothly, equally also can affect heat exchange property.Therefore, consider draining and heat exchange property, need to be optimized design to θ value.
The goal-setting that the heat exchanger performance caused with the end of evagination triangle increase drainage declines is for less than 1%.Can being obtained by the curve shown in accompanying drawing 9, for guaranteeing that PR is more than 99%, determining θ lower limit: θ >=85 °.
The goal-setting of the drainage growth rate increased with the end of evagination triangle increase drainage is for more than 50%.Can being obtained by the curve shown in accompanying drawing 10, for guaranteeing that drainage growth rate is more than 50%, determining the θ upper limit: θ≤105 °.
To sum up, for guaranteeing the drainage growth rate of more than 50% and the heat exchanger heat exchange property of more than 99%, θ optimum range is determined: 85 °≤θ≤105 °.
In above-mentioned example, the through hole of micro-channel flat is not limited to the shape described in accompanying drawing, and through-hole form can also be circle, ellipse, triangle, polygon etc., particularly, micro-channel flat is positioned at the through hole at two ends, and its shape will match with micro-channel flat two ends profile.
