The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Shown in Fig. 1 and 2, Fig. 1 is the structural representation of the utility model parallel-flow heat exchanger one embodiment, and Fig. 2 is the structural representation after flat tube among Fig. 1 and fin are installed.Present embodiment provides a kind of flat tube 10 of parallel-flow heat exchanger, and a plurality of fins 20 of spread configuration on this flat tube 10 be provided with water guide bar 30 in the orientation of fin 20, and this water guide bar 30 grip fin 20.
In the present embodiment, flat tube 10 is provided with the pipeline 101 that flows for refrigerant, and above-mentioned fin 20 is parallel being arranged on the flat tube 10 evenly, and fits with flat tube 10; The surface of flat tube 10 has the two water guide bars that relatively arrange, and this water guide bar 30 grips fin 20, after parallel-flow heat exchanger is in place, carries out hydrophilic treated.
During work, refrigerant flows from pipeline 101, cooperates with air by flat tube 10 and fin 20 and carries out exchange heat; In the process of exchange, spread the condensed water that produces on its surface under hydrophilic interaction; When condensed water diffuses to water guide bar 30 place, under the effect of water guide bar 30, will flow downward along this water guide bar 30, thereby the condensed water that produces on flat tube 10 and the fin 20 will be discharged.
The utility model is by arranging water guide bar 30 at flat tube 10, flowed along this water guide bar 30 by the condensed water that produces on water guide bar 30 guiding flat tubes 10 and the fin 20, therefore, the parallel-flow heat exchanger that the utility model provides can improve drainability, solved the problem that fin 20 bending parts in the prior art and fin 20 and the condensed water of the angle of flat tube 10 can't be discharged, and then reduced the air side resistance of parallel-flow heat exchanger, Effective Raise the exchange capability of heat of parallel-flow heat exchanger.
Particularly, above-mentioned water guide bar 30 is the column setting, such as cuboid etc.Its height and width can arrange according to actual needs, and in preferred present embodiment, the height of water guide bar 30 interval is 0.1mm to 2mm, and the width interval is 0.1mm to 2mm.
In the present embodiment, because the height of water guide bar 30 is arranged on 0.1mm to 2mm interval, it is interval that width is arranged on 0.1mm to 2mm, and the effect that condensed water is played drainage is better, has therefore further improved the drainability of parallel-flow heat exchanger.
Further, above-mentioned water guide bar 30 can be arranged on the middle part of flat tube 10, also can be arranged on the edge of flat tube 10.But, owing on the flat tube 10 two water guide bars 30 are set, grip fin 20 by this water guide bar 30, therefore the spacing between the two water guide bars 30 equals the width of fin 20.Therefore in the present embodiment, preferably water guide bar 30 is arranged on the edge of flat tube, thereby has increased the spacing between the water guide bar 30, increased simultaneously the width of fin 20, and then improved heat exchange area.Therefore the flat tube of the parallel-flow heat exchanger that provides of present embodiment has improved the exchange capability of heat of parallel-flow heat exchanger.
In conjunction with reference to Fig. 3 and shown in Figure 4, Fig. 3 is the structural representation of flat tube among Fig. 2, and Fig. 4 is the local structure for amplifying schematic diagram of A among Fig. 3.Above-mentioned water guide bar 30 and fin 20 relative drift angles are the chamfering setting, specifically as shown in the B among Fig. 4.In the present embodiment, thereby by being set at water guide bar 30, chamfering forms the guide portion that guide fins 20 is inserted two water guide bars, 30 centres, the angle of inclination of this guide portion can arrange according to actual needs, is not further qualified at this, inserts in the middle of the two water guide bars 30 as long as be convenient to fin 20.
