Abstract
The utility model relates to a string fin type radiating fin of a heat exchanger, which is used for enhancing the heat exchange effect. The utility model is provided with a hole 3 through which a heat exchange tube can pass, based on the existing tabular string fin 1. The circumference of the hole 3 is provided with a blade 2 salient to the tabular string fin 1. The radiating fin can enlarge the radiating area to cause the ascending thermal current to be disturbed strongly, and reduce the thickness of the bottom laminar flow to enhance the heat exchange effect.
Description
The utility model belongs to the heat-exchange apparatus parts, particularly the tabular string sheet of fin-tube radiator.
In existing fin-tube radiator, heat exchanger tube and flat fin are in series.When using this radiator, heated air-flow rises along the tabular fin surface, form thicker retention layer on its surface, so thermal resistance is bigger.
In addition, also have a kind of fin that is drilled with some holes on its surface, though it can make ascending air produce disturbance, improve the heat exchange effect of unit are, the area of dissipation of entire heat dissipation sheet greatly reduces, and therefore, generally speaking heat exchange effect may not increase to some extent.
The purpose of this utility model provides a kind of string sheet that can strengthen the heat exchange effect.
Below in conjunction with the description of drawings structure.
On tabular string sheet 1, be processed with for the hole 3 therefrom passed of heat exchanger tube (hot-water line or steam pipe), in the hole 3 around protruding blade 2 in flat board is arranged.
Use this fin, have more opportunity to contact when air-flow is moved from bottom to top, make the air-flow of rising produce strong disturbance, strengthen the heat exchange effect with radiating surface.
Embodiment:
Two long limits of rectangle metallic plate 1 to same direction bending certain width, are kept certain intervals so that go here and there between sheet when assembling.On rectangle metallic plate 1, be processed with the hole of passing for heat exchanger tube 3, in the hole 3 around have through line cutting punching press form to be quadrangle protruding in dull and stereotyped 1 blade 2, one group opposite side is separated with dull and stereotyped 1 after the warp cutting punching press, and another group opposite side links to each other with dull and stereotyped 1.The extended line on blade 2 and dull and stereotyped 1 both sides that are separated (line of cut) is all by the garden heart in hole 3, can make the heat that distributes from heat exchanger tube not be cut line like this and stop.Comply with the material and the thickness decision of string sheet through the blade 2 protruding height of line cutting punching stretch formation in flat board.Consider the spacing between the adjacent two string sheets of radiator, the blade 2 of projection is in the middle of the adjacent two string sheets.
Because the blade 2 of projection is arranged on tabular string sheet 1, therefore increased area of dissipation, make ascending air have more opportunity to contact with radiating surface, produce strong disturbance.In addition, because ascending air is not to resemble the existing plate radiating plate to keep away face along flat board and flow and rise always, but there are many discontinuity surfaces at the air flow stream place of mistake, like this with regard to attenuate the thickness of laminar sublayer, thermal resistance is greatly reduced.
The drawing explanation:
Fig. 1 is a front view of the present utility model, and Fig. 2 is its B-B profile, and Fig. 3 is its A-A profile.
Claims (2)
1, a kind of fin that strengthens the sheet string type heat exchanger of heat exchange effect, it is to be processed with the hole of passing for heat exchanger tube 3 on a tabular string sheet 1, it is characterized in that in the hole 3 around have protruding in dull and stereotyped 1 blade 2.
2, according to the said fin of claim 1, it is characterized in that said blade 2 is quadrangle, one group opposite side and tabular string sheet 1 are separated, and another group opposite side links to each other with tabular sheet 1, and the extended line on the both sides (line of cut) that blade 2 and tabular string sheet 1 are separated is the center of circle by hole 3 all.
