Finned heat exchanger is the most widely used a kind of heat transmission equipment in heat exchanger, and it is primarily of the formation such as heat exchanger tube, fin.Main heat exchange occurs in fin and meets near the front end face of hot-fluid, side front end face all comparison rule of hot-fluid met by the fin used in the market, the heat of surface near heat-exchange tube place of fin is lower by temperature after heat exchanger tube absorption, damage from long-pending the causing of the easy hot polymerization in fin position away from hot replace tubes, there is the space of improvement.
Utility model content
The utility model is to overcome defect in above-mentioned prior art, provides the heat exchanger fin that the distribution of a kind of heat is more balanced.
For achieving the above object, the utility model provides a kind of heat exchanger fin, comprise plate body, described plate body being provided with multiple row is pore spaced apart, heat exchanger tube inserts pore and plate body is fitted, and described plate body has corrugated edge, and the trough place that described plate body is met to the wavy edge of hot-fluid side is provided with U-type groove, described pore is positioned at the both sides of U-type groove, and the opening part that described plate body meets the close U-type groove in trough place at the corrugated edge to hot-fluid side is provided with viscous flow portion.
By above-mentioned setting, hot-fluid flows into plate body, the hot-fluid accumulating in trough place in a large number can continue to flow into plate body subsequent sections along U-type groove, because plate body subsequent sections is comparatively far away apart from hot-fluid inflow place, temperature is lower, effectively can absorb the after-heat of hot-fluid, thus avoid the damage that fin hot polymerization collection causes, the portion of viscous flow simultaneously can play slow hot-fluid, redistribute the effect of hot-fluid, makes heat exchange more thorough, improves heat exchanger effectiveness.
Be set to further: described viscous flow portion is arranged on the opening part of U-type groove and the connecting portion of plate body edge trough.
By above-mentioned setting, viscous flow portion produces a local resistance to hot-fluid, makes hot-fluid reduce flowing velocity at this, carries out the heat exchange of appropriateness with plate body.
Be set to further: described viscous flow portion is the inside projection of opening part being arranged on U-type groove, form the structure making U-type groove openings get smaller.
By above-mentioned setting, viscous flow portion produces a local resistance to hot-fluid, makes hot-fluid reduce flowing velocity at this, carries out the heat exchange of appropriateness with plate body.
Be set to further: described pore is provided with many rows, and the first comb number of perforations of meeting to hot-fluid side is no less than the pore number of rear row.
Be set to further: described plate body is provided with projection, described projection is arranged between adjacent two pores.
Be set to further: the cross section of described pore is for oval.
Be set to further: the edge of described pore is provided with flange.
Compared with prior art, the utility model arranges U-type groove by the trough place in otch side, hot-fluid enters along trough place, then continue to flow into along U-type groove, by the shunting action of U-type groove, hot-fluid can be led the heat exchanger tube place of U-lag both sides, to be absorbed by heat exchanger tube below, avoid from long-pending the causing of the fin position hot polymerization away from heat exchanger tube and damage.

Detailed description of the invention
Below in conjunction with accompanying drawing, a detailed description of the invention of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of detailed description of the invention.
The direction of arrow in Fig. 1 to Fig. 3 be hot-fluid flow to direction.
The utility model heat exchanger fin as shown in Figure 1, Figure 2 and Figure 3, comprise plate body 1, plate body 1 is provided with the pore 2 that multiple row is equally spaced, heat exchanger tube is connected with plate body 1 by inserting pore 2, the cross section of pore 2 is oval, also can be circular or other shapes, pipe 2 hole be arranged on plate body 1 can be same shape distribution, also can various shape combination distribute, pore 2 can arrange row according to actual needs, can for single or arrange more, when pore 2 be provided with arrange more time, first comb hole 2 number of meeting to hot-fluid side is no less than pore 2 number of rear row, the outer rim of pore 2 is provided with flange 6, thus is effectively adding the socket area of pore 2 with heat exchanger tube, thus improves the connection reliability of fin and heat exchanger tube, plate body 1 has corrugated edge 3, the trough place met to the edge 3 of hot-fluid side is provided with U-type groove 4, pore 2 is positioned at the both sides of U-type groove 4, the opening part of meeting to the close U-type groove 4 in the trough place of hot-fluid one example is provided with viscous flow portion 7, the center of U-type groove 4 and the center of trough are on the same axis, when meeting hot-fluid, when hot-fluid flows through viscous flow portion 7, viscous flow portion 7 plays slow hot-fluid and again divides the effect of hot-fluid to join, then hot-fluid continues to flow down along U-type groove 4, heat exchanger tube after being absorbed by the fin of U-lag both sides below and in pore 2, thus enable the heat of hot-fluid effectively disperse and be absorbed by heat exchanger tube, finless parts hot polymerization long-pending the causing avoided away from heat exchanger tube damages, improve the service life of fin, also improve heat exchanger effectiveness simultaneously.
Embodiment one, as shown in Figure 2, the connecting portion that viscous flow portion 7 is the opening part and plate body 1 edge 3 trough that are arranged on U-type groove 4, produces a local resistance to hot-fluid, makes hot-fluid reduce flowing velocity at this, carries out the heat exchange of appropriateness with plate body.
Implementation column two, as shown in Figure 3, viscous flow portion 7 is arranged on the inside projection of opening part of U-type groove 4, forms the structure making U-type groove 4 openings get smaller, produces a local resistance, make hot-fluid reduce flowing velocity at this to hot-fluid, carries out the heat exchange of appropriateness with plate body.
Further setting, plate body 1 is provided with protruding 5, protruding 5 (are also between two rows when the many rows of pore are arranged) between adjacent two tubulation holes 2, the center of the preferred center of protruding 5 and U-type groove 4 on the same axis, the i.e. center of protruding 5, the center of U-type groove 4, center three's conllinear of trough, thus the positive protrusions 5 of the hot-fluid flowing through U-type groove 4, along the arc surface shunting of protruding 5, be divided into the heat of two strands less, heat energy can be exchanged by dispersion utilize, the turnup structure of preferred protruding 5 circular ports that are punching, therefore this projection 5 can also use as heat regulation hole, promote that hot-fluid circulates along the direction in hole, improve heat exchange efficiency, this projection 5 also can by striking out independent projection or spot welding formation.
Compared with prior art, the utility model effectively can carry out dispersion absorption by heat, and the heat local accumulation avoiding fin causes the long-pending damage of hot polymerization.
Be only a specific embodiment of the present utility model above, but the utility model is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
