Abstract
The utility model relates to a spiral micro-channel type heat exchanger which comprises heat exchange tubes. A spiral separating strip is arranged in each heat exchange rube in a sleeved mode, and micro-channels are defined by each spiral separating strip and the inner wall of each heat exchange tube. The spiral micro-channel type heat exchanger simultaneously has the advantages of an existing micro-channel heat exchanger and the advantages of an existing ordinary heat exchanger, wherein the existing micro-channel heat exchanger has the advantages of improving heat transfer, being ultra-low in refrigerant charge, reducing the size and the like, and the existing ordinary heat exchanger has the advantages that air resistance is low, and condensate water on the surfaces of fins can be easily discharged when the existing ordinary heat exchanger serves as an evaporator. Due to the fact that the spiral micro-channels are defined by each spiral separating strip and the inner wall of each heat exchange tube, a refrigerant carries out spiral flow around the inner wall of an outer tube, and the effect of heat exchange is further improved.
Description
Technical field
The utility model relates to a kind of air-conditioning equipment technical field of heat exchangers, particularly a kind of spiral micro-channel type heat exchanger.
Background technology
Micro-channel heat exchanger is the new-type heat exchanger of carrying often nearly one or two years, and it refers to by 0.05-0.1in. (1-2.5mm) thick, and 0.5-1in. (12-25mm) is wide, the heat exchanger that inside is made up of the heat exchanger tube of the gentle helix passage of many 0.5-1mm.Though this hot device used on air conditioning for automobiles (single cold type) and water tank a lot of years, the application on family expenses and business air conditioner and refrigeration product is few.
China Patent No. CN03101676.6 discloses a kind of storage tank and end cap assembly that uses for the microchannel tubing with heat exchanger on July 30th, 2003, includes a flat tubing, and this tubing has a plurality of inner perforated that extend to its end.An end cap includes one and is used for holding the groove of receiving tubing, and this end cap correspondingly is placed in again in the storage tank.
Through experimental test, use above-mentioned micro-channel heat exchanger as condenser, can produce following beneficial effect.
1, heat exchange amount increases by 10%;
2, refrigerant charging reduces 30%;
3, the wind collateral resistance reduces 50%.
In conjunction with researching and analysing, the summary of benefits of micro-channel heat exchanger is as follows now.
(1) strengthens heat transfer, improved heat transfer efficiency;
(2) dwindled heat exchanger volume;
(3) reduced filling of cold-producing medium;
(4) the air side resistance reduces, required blower fan, and the rating of electric machine reduces;
(5) because be that full aluminum is made, and cost decline (but because there is not scale effect, only refer to material cost, single product is still expensive than same specification fin tube type);
(6) better corrosion resistance is arranged;
(7) the pipe internal pressure loss is little;
(8) easy field patch leak point.
The shortcoming of micro-channel heat exchanger is summarized as follows now.
(1) for evaporimeter, separatory is a major issue, can't finely solve now;
(2) for evaporimeter, the quick discharge of condensed water does not also have fine solution, and this derives frosting defrost problem again;
(3) because the air side resistance reduces, the inhomogeneities of air-flow is worsened more;
(4) design flexibility reduces, as sub-load, and the design of supercooling tube section etc.
The utility model content
The purpose of this utility model is to overcome the deficiency that above-mentioned prior art exists, and provides a kind of simple and reasonable for structure, and cost is low, efficiency is high, volume is little, the spiral micro-channel type heat exchanger of good effect of heat exchange, to overcome the deficiencies in the prior art.
The purpose of this utility model is to realize like this.
The spiral micro-channel type heat exchanger comprises heat exchanger tube, it is characterized in that: be arranged with the helical form divider in the described heat exchanger tube, surround the gentle helix passage between helical form divider and the heat exchanger tube inwall.
The purpose of this utility model can also adopt following technical measures to solve.
As a kind of scheme more specifically, described helical form divider is provided with at least two, and a side of each helical form divider links together, and the opposite side of each helical form divider and heat exchanger tube inwall join.
Described heat exchanger tube is the rounded round tube of end face.
Also comprise radiating fin, isocon and framework, described heat exchanger tube is provided with many, the gentle helix passage of each root heat exchanger tube and isocon internal communication, and radiating fin is set in outside the heat exchanger tube, and radiating fin also is fixed in the framework.
The beneficial effects of the utility model are as follows.
(1) this kind of micro-channel heat exchanger has the advantage of existing micro-channel heat exchanger and existing common heat exchanger simultaneously, and wherein, the advantage of existing micro-channel heat exchanger is: have augmentation of heat transfer, extremely low refrigerant charge, reduce heat exchanger volume etc.; The advantage of existing common heat exchanger is: air drag is little, and when making evaporimeter, the draining of fin surface condensed water is easy;
(2) this kind of micro-channel heat exchanger surface structure form and original finned heat exchanger keep unified, can replace original finned heat exchanger fully;
(3) technology is simple, can implement this scheme at the coil pipe production line of now, effectively reduces product cost;
(4) surround the gentle helix passage between helical form divider and the heat exchanger tube inwall, make cold-producing medium center on outer tube wall and spin mobilely, further strengthen the heat exchange effect.
