Abstract

The utility model relates to an improved radiating fin which has a rectangular n-shaped groove, wherein the front and the rear ends of the two sides of the upper surface of the n-shaped groove are provided with ear clips; the front and the rear ends of the inner edges of the extending two sides of the lower part of the n-shaped groove are provided with grooves; convexly diagonal clamping corners are arranged in the grooves and are corresponding to the ear clips on the upper surface of the n-shaped groove. When two radiating fins are assembled, the ear clips on one radiating fin can be jointed with the clamping corners of the other radiating fin. Thus, the outer edges of the jointed radiating fins are flat. Thus, an integral lager heat radiating area is formed so as to increase the heat radiation. By the design of the hidden grooves and the clamping corners, the wind resistance of a radiating fan arranged on the radiating fins can be reduced so as to increase the wind flow. Therefore, the radiating fins can exert a better heat radiating efficiency for improving the economic value of practicability.

Description

The structural improvement of fin

Technical field

The utility model relates to a kind of structural improvement of fin, makes the preferable heat radiation function of fin performance especially, to promote the economic worth of practicality.

Background technology

Press, the structure of habit formula fin 1, as shown in Figure 1, its top more than 11 is made as concavo-convex, and that bottom more than 12 is made as is horizontal, and on the top, 11,12 2 corresponding front and back ends edges, the end respectively are equipped with gusset plate 13, in order to when fin 1 during with fin 1 winding, with the gusset plate 13 of gusset plate 13 another fin of connection of a fin 1.

From the above, after the winding of habit formula fin 1 is finished, though can reach the effect of heat radiation, yet because of all being, the gusset plate 13 on the fin 1 of learning martial arts exposes design, and very not attractive in appearance, and the gusset plate 13 of 1 outer rim of the fin after the winding, cause the minimizing of endotherm area, and the increase windage, and influence is installed in the air quantity of the radiator fan on the fin 1, and then reduce the heat radiation function of fin 1.

The whence is, because the disappearance of above-mentioned habit formula heat radiating fin structure, the inventor is with the experience of being engaged in related industry for many years and professional technique, and adhering to research innovation, excelsior spirit, it is wider and meet the structural improvement of the fin of industrial utilization to work out a kind of more practicality and range of application.

Summary of the invention

Main purpose of the present utility model, system is a rectangle Jiong groove with heat sink design, order makes the fin outer rim after the winding be plane formula, form complete big area of dissipation, increasing heat radiation, and the concealed design by above-mentioned groove, Ka Jiao, it is attractive in appearance to practise the formula fin, and order makes the radiator fan that is installed on the fin can lower windage and increase air quantity, so that the preferable heat radiation function of fin performance.

The utility model adopts technical scheme as described below for achieving the above object: a kind of structural improvement of fin, system makes the preferable heat radiation function of fin performance, this fin is rectangular Jiong groove, its surperficial two side front and back ends appropriate locations in Jiong groove top respectively are provided with earclip, and the front and back ends appropriate location on edge respectively is provided with groove in Jiong groove below extension two sides, be provided with the Ka Jiao that is convex oblique shape in the groove, just the earclip with surface, above-mentioned Jiong groove top forms corresponding; Winding state between fin, the Ka Jiao of another fin of earclip snapping of a fin, the fin outer rim after the winding is plane formula, forms complete big area of dissipation.

Adopt the utility model of said structure, when fin and fin winding, Ka Jiao with another fin of earclip snapping of a fin, order makes the fin outer rim after the winding be plane formula, form complete big area of dissipation, increasing heat radiation, and by the concealed design of groove, Ka Jiao, so that the radiator fan that is installed on the fin can lower windage with the increase air quantity, and reach the purpose of preferable heat radiation.

The specific embodiment

See also shown in Figure 2, the utility model system makes the preferable heat radiation function of fin 2 performances, its characteristic is: this fin 2 is rectangular Jiong groove, its surperficial two side front and back ends appropriate locations in Jiong groove top respectively are provided with earclip 21, and extension two side outer rims in Jiong groove below are smooth, and front and back ends appropriate location on edge respectively is provided with groove 22 in it, is provided with the card angle 23 that is convex oblique shape in the groove 22, and just the earclip 21 with surface, above-mentioned Jiong groove top forms corresponding.

As shown in Figure 3, when fin 2 and fin 2 windings, card angle 23 with another fin 2 of earclip 21 snappings of a fin 2, at this moment, earclip 21 buckles in the groove 22, person as shown in Figure 4, and the vacancy just fastens card angle 23 in the groove 22 in the earclip 21, order makes fin 2 outer rims after the winding be plane 24, form complete big area of dissipation, dispel the heat, and pass through the concealed design of groove 22, card angle 23 shapes to increase, so that the radiator fan that is installed on the fin 2 can lower windage with the increase air quantity, and reach the purpose of preferable heat radiation.

To sum up institute is old, the structural improvement of the utility model fin, and the structure of obviously practising the formula fin has more the value of economy and practicality, is the effect with novelty and progressive in fact, and does not see the also unexposed use of publication before the application, and the whence is submitted patent in accordance with the law.

Claims

1, a kind of structural improvement of fin, it is characterized in that: this fin is rectangular Jiong groove, its surperficial two side front and back ends appropriate locations in Jiong groove top respectively are provided with earclip, and the front and back ends appropriate location on edge respectively is provided with groove in Jiong groove below extension two sides, be provided with the Ka Jiao that is convex oblique shape in the groove, just the earclip with surface, above-mentioned Jiong groove top forms corresponding; Winding state between fin, the Ka Jiao of another fin of earclip snapping of a fin, the fin outer rim after the winding is plane formula, forms complete big area of dissipation.
