Abstract
The invention provides a fin used for heat exchangers. The fins are wavy in general and are arranged between heat dissipation pipes of the heat exchanger as well as between the heat dissipation pipes and side plates, and peak parts and trough parts of the fins are connected with two adjacent heat dissipation pipes or with the side plates and the heat dissipation pipes respectively. The fin is characterized in that at least one of the peak parts and the trough parts is provided with a first nick part. By providing the peak parts or the trough parts of the fins or simultaneously providing both the peak parts and the trough parts with nick parts, the original smooth peak parts and the trough parts are divided into a plurality of sections, and then condensed water produced by a heat-exchange process flows to the surfaces of the heat dissipation pipes through the nick parts and is discharged out of the heat exchanger along the heat dissipation pipes so as to prevent excessive condensed water from accumulating on the surfaces of the fins and improve the efficiency of heat exchange. Meanwhile, as the nick parts are formed by turning over part of fin materials of the peak parts or the trough parts towards the inside of the fins, air can be obstructed by over-turned parts when flowing past the fins, thus turbulent flow can be produced so as to further improve the efficiency of heat exchange.
Description
Technical field
The present invention relates to technical field of heat exchange, particularly a kind of fin structure for heat exchanger that is used for air-conditioning duct.The invention still further relates to a kind of heat exchanger that comprises above-mentioned fin.
Background technology
Heat exchanger is an equipment of realizing that heat transmits between cold and hot fluid, is widely used in fields such as HVAC.
Please refer to Fig. 1, Fig. 1 is the structural representation of a kind of typical heat exchanger in the prior art.
Fig. 1 is the structural representation of a kind of typical heat exchanger in the prior art.Heat exchanger 1 comprises first header 11, second header 12 that is parallel to each other, and both can be provided with usually abreast, and have the many radiating tubes that be arranged in parallel substantially 13 between the two; The cross section of radiating tube 13 mostly is flat, and usually the passage of radiating tube 13 is separated into several, and described passage is also referred to as the microchannel.Respectively be provided with a plurality of radiating tube interface (not shown)s on first header 11 and second header, the 12 corresponding tube walls, the two ends of radiating tube 13 are gone in described first header 11 and second header 12 by described radiating tube interface plug-in mounting respectively, thereby both are communicated with.
In order to realize heat exchange as far as possible fully, can in first header 11 and/or second header 12, some lateral partitions (not shown)s be set, thereby the heat transferring medium circulation passage in the heat exchanger 1 can be made as the snakelike of bending; Therefore described heat transferring medium flows into first header 11 from feed tube 17, and in each bar radiating tube 13 lateral flow, finally outflow heat exchanger 1 from discharging tube 18.Illustrated feed tube 17 and discharging tube 18 are arranged on the aspect, the same side of first header 11, and also can be separately positioned on first header 11 and second header 12 when using usually.
Flow out through the opposite side (air draft side) of said external air automatic heat-exchanger 1 after the heat exchange on the flow through surface of above-mentioned radiating tube 13 and fin 14 of one side (inlet side) of extraneous air automatic heat-exchanger 1.
In order further to improve heat exchange efficiency, usually between adjacent radiating tube 13, and between radiating tube 13 and last side plate 15, time side plate 16 fin 14 is set.
Fig. 2 is a kind of typical fin structure schematic diagram in the prior art; Fig. 3 is a heat exchanger partial elevational cross-sectional schematic shown in Figure 2.
It is wavy that fin 14 is substantially, has a series of bodies 144, and a series of crest portions 141 and the trough portion 142 that connect body 144; Because air is when smooth body surface flows through, can produce the very thin boundary layer of one deck at body surface, air in the boundary layer can not flow, add the heat exchange effect in order to strengthen, usually each body 144 is provided with a series of shutters 143, the effect of shutter 143 is to break the boundary layer that fin body portion 144 surfaces produce, and improves heat exchange efficiency.Radiating tube 13 or go up side plate 15, side plate 16 is down fixedlyed connected respectively in crest portion 141 and trough portion 142.Wherein, crest portion 141 and trough portion 142 all are circular arc, when fin 14 and radiating tube 13 or go up side plate 15, side plate 16 welding fixedly time the down, crest portion 141 and trough portion 142 and radiating tube 13 or the arc surface of going up the contact portion of side plate 15, following side plate 16 become a plane usually.
When heat exchanger 1 is in the evaporation operating mode, the high temperature air (generally being equivalent to about indoor temperature 28 degree) that contains steam enters from the inlet side, pass the space between the body 144 of fin, and the cold-producing medium that is in the radiating tube that is arranged in parallel 13 between the fin 14 carries out heat exchange.Heat exchange is a lasting process, and the high temperature air that contains steam is in the middle of the process of carrying out heat exchange, and temperature reduces gradually, becomes the air of relative low temperature after the air draft side is discharged; In the middle of this process, when the surface temperature of heat exchanger was lower than the condensation temperature of the air that is in contact with it, airborne part steam can condense into water, and the condensed water of separating out is deposited in the surface of fin and radiating tube.
As shown in Figure 3, because fin is wavy in the prior art, and the crest portion of fin and trough portion are bigger to the surface tension and the adhesion of water, therefore, condensed water accumulates in drift angle 145 places of fin easily, and promptly near the position of crest or trough, condensed water is difficult for discharging.And too much condensed water is piled up, and understands blocking portion circulation of air path, thereby influences the heat exchange property of heat exchanger.Simultaneously, the fin structure of prior art, high temperature air is in the middle of the process of fin of flowing through, when particularly flowing through the crest portion of fin or trough portion, be basically, do not hindered along straight-line pass, be unfavorable for that air produces turbulent flow, thereby also can influence the heat exchange property of heat exchanger.
So, how making the condensed water that produces in the heat exchanging process, the condensed water that especially accumulates in fin crest portion, trough portion is more prone to discharging, and improves the heat exchange property of heat exchanger, is the present technical issues that need to address of those skilled in the art.

Description as background technology, when heat exchanger is in the evaporation operating mode, the high temperature air (generally being equivalent to about indoor temperature 28 degree) that contains steam enters from the inlet side, pass the space between the body 144 of fin, and the cold-producing medium that is in the radiating tube that is arranged in parallel 13 between the fin 14 carries out heat exchange.Because heat exchange is a lasting process, the high temperature air that contains steam is in the middle of the process of carrying out heat exchange, and temperature reduces gradually, becomes the air of relative low temperature after the air draft side is discharged; In the middle of this process, when the surface temperature of heat exchanger was lower than the condensation temperature of the air that is in contact with it, airborne part steam can condense into water, and the condensed water of separating out is deposited in the surface of fin and radiating tube.When adopting the fin that present embodiment provided, the condensed water that may be deposited in the drift angle place of fin trough portion originally can be along the mobile direction of air under the wind-force effect, flow to flange 146 places along trough portion 142, run into the obstruction of flange 146, most of condensed water just flows to first notch part 147 along the two ends of connecting portion 148, arrive the surface of radiating tube 13, and along radiating tube 13 outflow heat exchangers.
In the present embodiment, flange 146 is towards the certain angle of inside turnover of fin 14, when air is flowed through fin, drift angle place in crest portion 141 or trough portion 142, will run into obstruction, thereby make air produce turbulent flow, the existence of turbulent flow at each obstruction place, increased the time of contact of air and radiating tube 13, increased the heat exchange efficiency of heat exchanger.
Below in conjunction with Fig. 7, Fig. 8 second embodiment of the invention is described.Fig. 7 is the schematic top plan view that the fin of second embodiment of the invention is part trough portion when launching shape; Fig. 8 is the cutaway view of D-D direction shown in Figure 7.
Second embodiment is the improvement to first embodiment, because, because the space between fin crest portion or the trough portion is narrow usually, therefore with flange 146 during towards the fin internal bend, flange 146 ' long limit might conflict on the body 144 of fin 14, for fear of this situation, can with flange 146 ' both sides bend once more, in the present embodiment, with flange 146 ' two ends bend, the direction of concrete bending can with flange 146 ' the turnover direction identical, also can with flange 146 ' the turnover direction opposite, thereby make flange 146 ' shape approach rectangle, form two kinks 149 simultaneously.
It is to be noted, can carry out certain variation to present embodiment, such as can be not yet to flange 146 ' both sides bend once more, and directly flange 146 ' both sides are carried out cutting, make flange 146 ' shape approach rectangle, fan annular, triangle and other any possible shape.
Other structure and the operation principle of present embodiment are identical with first embodiment, give unnecessary details no longer one by one at this.
Below in conjunction with Fig. 9, Figure 10 the 3rd embodiment of the present invention is described.Fig. 9 is the schematic top plan view that the fin of third embodiment of the invention is part trough portion when launching shape; Figure 10 is the cutaway view of E-E direction shown in Figure 9;
The 3rd embodiment is the further improvement to first embodiment, in the first embodiment, the interface width of the width of connecting portion 148 and trough portion 142 and radiating tube 13 is roughly the same, in the present embodiment, connect 148 ' width be slightly less than the interface width of trough portion 142 and radiating tube 13, like this connecting portion 148 ' two ends just formed two throughput 1481,1482.When condensed water direction along air intake under the wind-force effect, and flow to flange 146 along trough portion 142 obstruction of " locating; can run into flange 146 ", and because the existence of throughput 1481,1482, condensed water just can flow to first notch part 147 along throughput 1481,1482, arrive the surface of radiating tube 13, and along radiating tube 13 outflow heat exchangers.Compare with first embodiment, can reduce the resistance in the mobile process of condensed water.
Below in conjunction with Figure 11 the 4th embodiment of the present invention is described.Present embodiment is the further optimization to above each embodiment.
In the present embodiment, in crest portion 141 or trough portion 142, offer a series of notch parts 147, the density that is provided with of notch part 147 reduces gradually in the direction (the figure hollow core direction of arrow) along air intake, promptly in a side near air inlet, because the static pressure of wind is relatively large, in addition, the fin of close air inlet part can produce more condensed water near the fin part of air outlet, so can make the spacing between the notch part 147 smaller; And near a side of air outlet,, in addition, can produce less condensed water near the fin part of air inlet near the fin part of air outlet because the static pressure of wind is less relatively, therefore, the spacing between the notch part 147 can be provided with big.Like this, in heat exchanging process,, can make each notch part 147 can reach drainage effect relatively uniformly, can avoid simultaneously the overstocked intensity that has influence on fin in ground being set because of notch part 147 along air air intake direction.
As improvement to above four embodiments, the a plurality of notch parts that are arranged in arbitrary crest portion or the trough portion can also be divided into many groups, every group of notch part that comprises equal number, and the flange direction in every group is identical, flange direction opposite (this direction is meant the turnover direction of flange towards fin inside, and promptly flange equates with the angle of crest portion or trough portion) between group; Wherein, optimum setting is that notch part is divided into two groups, as shown in figure 11.Such breach design structurally is symmetrical, is convenient to processing and manufacturing.
The described heat-exchanger fin 14 of above embodiment all have towards the flange 146/146 of the inner turnover of fin '.When the heat exchanger that uses this fin when being in the evaporation operating mode, air enters between a series of bodies 144 of fin 14, and move, and after the cold-producing medium in the radiating tube 13 between fin carries out heat exchange at interval, discharge from opposite side along the width of fin 14.Because among the present invention, the crest portion 141 of fin 14 or trough portion 142 be provided with towards the flange 146/146 of fin inside ', air will meet with obstruction in running, thereby produces turbulent flow in the part, has improved the heat exchange efficiency of heat exchanger.
More than heat exchanger provided by the present invention and fin thereof are described in detail.Used specific case herein principle of the present invention and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present invention and core concept thereof.Should be understood that, for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also carry out some improvement and modification to the present invention, such as, in arbitrary embodiment, the shape of flange can also be that any possible shape the 3rd embodiment or the flange in the 4th embodiment also can adopt second embodiment described bending or cutting once more except trapezoidal, fan annular, triangle; In arbitrary embodiment, connecting portion 148 is parallel with the finned length direction, can certainly be arranged to and certain angle of the finned length deviation of directivity or the like.These improvement and modification also fall in the protection domain of claim of the present invention.
