Abstract
The utility model relates to a straight line micro-channel type heat exchanger which comprises a heat exchange pipe. An inner pipe is sleeved inside the heat exchange pipe, a port of the inner pipe is closed, and a micro channel is formed between the outer wall of the inner pipe and the inner wall of the heat exchange pipe. The straight line micro-channel type heat exchanger has the advantages that the micro-channel type heat exchanger simultaneously has the advantages of an existing micro-channel type heat exchanger and the advantages of an existing common heat exchanger, wherein the existing micro-channel type heat exchanger has the advantages of reinforcing heat transfer, being low in cooling agent filling quantity, reducing the size of the heat exchanger and the like, the existing common heat exchanger has the advantage that air resistance is small, and when the existing common heat exchanger is used as an evaporator, condensate water on the surface of a fin is easily drained, the exterior structure type of the straight line micro-channel type heat exchanger keeps consistent with an original fin-type heat exchanger, the straight line micro-channel type heat exchanger can completely replace the original fin-type heat exchanger, the process is simple, the scheme can be implemented on an existing coil pipe production line, and product cost can be effectively reduced.
Description
Technical field
The utility model relates to a kind of air-conditioning equipment technical field of heat exchangers, particularly a kind of straight line 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 minim channel 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 straight line 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 straight line micro-channel type heat exchanger comprises heat exchanger tube, it is characterized in that: be arranged with interior pipe in the described heat exchanger tube, the sealing of inner tube mouth forms minim channel between outer wall of inner tube 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 in pipe consistent with the heat exchanger tube end surface shape, between outer wall of inner tube and the heat exchanger tube inwall everywhere apart from equating.
Described outer wall of inner tube is provided with at least two along its axis direction and separates convex tendon, and each is separated convex tendon and equidistantly is distributed in interior pipe periphery, and the outer surface of separating convex tendon contacts with the heat exchanger tube inwall.Extend in view of separating the convex tendon axis direction, extend so minim channel also is axis, the refrigerant in the minim channel is along the minim channel streamlined flow.
Pipe is the rounded round tube of end face with heat exchanger tube in described.Certainly, interior pipe and heat exchanger tube also can be other shapes, as: as described in pipe be end face and be oblate flat tube with heat exchanger tube; Perhaps, described interior pipe and heat exchanger tube are the elliptical tube of end face ovalize.
Also comprise radiating fin, isocon and framework, described heat exchanger tube is provided with many, the minim channel 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.
As another kind of scheme more specifically, described heat exchanger tube inwall is provided with at least two along its axis direction and separates convex tendons, and each is separated convex tendon and equidistantly is distributed in week in the heat exchanger tube, and the outer surface of separating convex tendon contacts with the heat exchanger tube inwall.This scheme is with the different of a last scheme: separation convex tendon and the heat exchanger tube of this scheme are one-body molded, and the separation convex tendon of a last scheme and interior pipe are one-body molded.
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.
