Abstract
The invention discloses a flat tube heat exchanger structure, which comprises fins with ducts and a flat tube fixedly connected with the fins, wherein the opening ends of the U-shaped ducts are arranged at two ends of the fins. The invention also discloses an assembling method, which comprises the following steps of: 1) piling and fixing the fins, and correspondingly fixing flat tubes on a fixed platform; 2) moving the fixed platform to ensure that the flat tubes are inserted into the ducts correspondingly; 3) applying push force until the flat tubes enter the ducts; 4) fixing through welding, gluing or interference fit; and 5) connecting two ends of the flat tubes with an inlet collecting pipe and an outlet collecting pipe. In the structure, the U-shaped ducts are arranged on the fins, and the flat tubes are inserted from the transverse direction of two sides of two fins, so that the travel of inserting the flat tubes into the fin group is reduced, the flat tubes are inserted symmetrically to avoid the situation that the fins are deformed because the fins are stressed at one side. The novel fin structure is easier to assemble and increase the contact area, and has good and uniform heat radiation property, so that the product performance is improved.
Description
Technical field
The present invention relates to a kind of condenser, particularly a kind of parallel-flow heat exchanger structure and assembly method thereof.
Background technology
When room air conditioner moved at cooling condition, the room air evaporimeter of flowing through made temperature reduce.Simultaneously because the temperature of evaporator surface generally is starkly lower than the dew-point temperature of air, so air is when flowing through evaporator surface, and airborne part moisture will be separated out, thereby forms condensate water at evaporator surface.Condensate water at evaporator surface should in time be drained, if it is more that condensate water is gathered at evaporator surface,, increase the flow resistance of air with the obstruct airflow road, the efficient of evaporimeter will be reduced: water droplet also might take place be blown into indoor situation, cause the off quality of air-conditioner.
Fin-tube heat exchanger is a heat exchanger pattern with the most use in the present refrigerating air conditioning device, and room air conditioner and air-cooled handpiece Water Chilling Units mostly adopt this heat exchanger.This heat exchanger is adding man-hour, is punching on fin, flange, and the height of flange is the spacing between fin, and the annulus that flange forms is enclosed within on the pipe, makes that fin is able to by this annulus and pipe excellent contact be arranged, and improves heat transfer efficiency.
Fig. 1 is the parallel-flow heat exchanger structural representation of prior art air-conditioning.Fig. 2 is the cross sectional view of heat exchanger structure shown in Figure 1.As Fig. 1, shown in Figure 2, the multiple input multiple output type tube-strip heat exchanger structure of prior art, the flat tube 2 that it comprises fin 3 and runs through fin 3, wherein said flat tube is the microchannel aluminium flat conduit, in order to guarantee that flat tube 2 has good thermal diffusivity with combining of fin 3, what adopt is that the mode of welding combines both, the upper end of flat tube 2 and inlet header 1 are welded to connect communicatively, the lower end of flat tube 2 and outlet header 4 are welded to connect communicatively, thereby the refrigerant in the inlet header 1 disperses to flow in a plurality of flat tubes 2, be compiled in the outlet header 4 through after the heat exchange, facilitate heat exchanger like this and be connected with exterior line.
But when assembling, fold fin earlier, perpendicular again insertion flat tube assembles; It is bigger that flat tube inserts stroke from the low side of fin to the top, bigger to the flange influence of fin, causes the spacing of fin to be difficult to determine, and then can have a negative impact to fitting between fin and the flat tube, reduces the radiating efficiency of heat exchanger.
Fig. 3 is the automobile heat radiating fin structure schematic diagram of prior art.As shown in Figure 3, it comprises flat tube 12 and fin 13, when assembling described flat tube two ends be provided with solder coat, Wavelike finnedly carry out high temperature brazing after being fixed between two flat tubes, though can obtain that intensity whole production complex process cost is higher preferably.
In sum, in the prior art, flat tube need rely on welding with being connected of fin, and the wayward failure welding that often occurs of welding procedure causes product quality problem.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiency that above-mentioned fin-tube heat exchanger exists, and provides a kind of in conjunction with the advantage of automotive heat exchanger and advances to have more the new structure condenser more, and it has higher heat dispersion and intensity, and stability simple to operate is high.
The technical solution adopted in the present invention is:
A kind of flat pipe heat exchanger structure, it comprises fin that offers pipe-line tank and the flat tube of fixedlying connected with described fin, described pipe-line tank is " U " shape, and its openend is arranged on the both sides of fin.
Described flat tube is a micro-channel flat.
The width of described pipe-line tank is than the big 0.2-0.5mm of thickness of flat tube.
Be provided with flange around the described pipe-line tank.
The openend of described " U " pipe-line tank is crisscross arranged in the both sides of fin.
Be crisscross arranged in the both sides of fin the openend double space of described " U " pipe-line tank.
A kind of assembly method of flat pipe heat exchanger as claimed in claim 1 comprises following steps:
1) fin is piled up and fixing, with flat tube compartment of terrain respective fixation at fixed station 30 and fixed station 40;
2) fixed station 30 of mobile both sides and fixed station 40 simultaneously make flat tube insert the pipe-line tank accordingly from both sides simultaneously;
3) continue to apply even thrust enters pipe-line tank until flat tube inside;
4) then by welding, gluing or interference fit further fixedly flat tube and fin;
5) two ends of flat tube and inlet header and outlet header are welded to connect respectively.
Be taken up in order of priority mobile fixed station and so that flat tube is successively inserted the fin both sides.
The invention has the beneficial effects as follows: the present invention will be provided with " U " pipe-line tank on fin, can insert flat tube from two fin both sides horizontal directions simultaneously, reduce the stroke that flat tube inserts fins set, insert symmetrically, the stressed situations such as distortion that cause of fin one side have been avoided, improve contact area between fin and the flat tube, thereby improved thermal resistivity, improve radiating efficiency.Easier realization assembling of this novel fin structure and raising contact area.Good heat dissipation and even has improved properties of product.
