Abstract

The utility model discloses a design related to the radiating fins, in particular to an improved structure of radiating fins increasing the strength of structure in the assembly of the radiating fins and the area of contact of the radiating pipes. The utility model arranges complex number of punched holes plugged by the radiating pipes in the radiating fins, and the outer edge of each punched hole is provided with a through hole used for the welding rods to cross through or to be injected the solder paste and the dissolvant. The proper distance are kept between the through hole and the punched hole simultaneously. In this way, the welding rods, the solder paste or the dissolvant can be melted in the through using the hot melting way, the molten liquid after being melted can be coated on the outer edge of the radiating pipe and be attached to the radiating fins between the edge of the punched hole and the through hole, so the joint area between the radiating pipe and the radiating fins is increased, and the heat conduction efficiency between the radiating pipe and the radiating fins can also be increased.

Description

The heat radiating fin structure improvement

Technical field

The utility model relates to a kind of heat radiating fin structure improvement, refers to the design that a kind of fin engages with radiating tube especially.

Background technology

Heat dissipation problem is for influencing the most serious problem of 3C Product development now, how to improve radiating efficiency with one of topic of becoming all circles and vying each other.

Traditional heat abstractor utilizes radiating fin to cooperate fan to relieve the heat energy of 3C Product, and this radiating fin system is constituted with metal products such as copper or aluminium, and the group of utilizing radiating fin establishes the area that increases heat exchange, and the mode of utilizing radiating fin to carry out heat exchange is purely applied and used.

So, in the streets go up also to have and utilize combining of radiating fin and radiating tube, increase radiating efficiency, and in conjunction with the mode of radiating fin and radiating tube, head overweights the number of the contact area between radiating fin and radiating tube, as shown in Figure 1, be a combination of commonly using fin A and radiating tube 20, it mainly lies in a Durchgangshohle A1 is set on the fin A, and be extended with the junction surface in a side of radiating tube 20 tops, and Durchgangshohle A1 upper limb is provided with the less pore A2 of a bore, and fin A is socketed on the radiating tube 20 by Durchgangshohle A1, and wire 40 is placed among the pore A2 of fin A upper limb, with hot melting way radiating tube 20 is engaged with fin A again and become one.

Above-mentioned wire 40 is the lateral margin that is arranged in radiating tube when wearing, and makes radiating tube 20 produce the effect that engages with fin A via hot melting way; Yet, when wire 40 utilizes hot melting way and melts, liquation after the welding can flow downward, and causes radiating tube 20 and fin A when combining, and only utilizes the inner margin portion of Durchgangshohle A1 to reach the effect that engages with the outer rim of radiating tube 20, so, radiating tube 20 engages effect quite built on the sand with fin A's, is easy to generate to engage unreally, or is subjected to external impacts and produces the situation of be full of cracks, make between radiating tube 20 and the Durchgangshohle A1 and produce the gap, and influence the heat conduction efficiency between radiating tube 20 and fin A greatly.

The utility model content

The purpose of this utility model is to provide a kind of hot melting way that sees through with the bonding area between increase fin and radiating tube, and then increases the heat radiating fin structure improvement of fin radiating effect.

For achieving the above object, technical solution of the present utility model is: a kind of heat radiating fin structure improvement, mainly lie in this fin and be provided with a plurality of perforation that supply radiating tube to plug, each outer rim of boring a hole is provided with to use for welding rod and wears or in order to inject the through hole of tin cream, flux, maintain suitable distance between this through hole and perforation, and be provided with the spacing arc groove identical with piercing aperture unanimity and quantity in the fin upper end.

Described welding rod is made of low melting material.

After adopting such scheme, owing to use on the utility model fin between the perforation that wears or plug in order to the through hole that injects tin cream, flux and confession radiating tube for welding rod and maintain suitable distance, therefore after utilizing hot melting way that welding rod or tin cream or flux are fused in through hole, the liquation that is produced is owing to have the characteristic that flows downward, make liquation can be coated on the outer rim of radiating tube, and be attached on the fin between perforated edge and the through hole, thereby increase the bonding area between radiating tube and fin, and then increase the hot transfer efficiency between radiating tube and fin.

The element numbers explanation

A fin A1 Durchgangshohle A2 pore

10 fin, 11 perforation, 12 through holes

13 spacing arc groove 20 radiating tubes 30 welding rods

31 hot melt liquid, 40 wires

Embodiment

The structure of heat radiating fin structure improvement described in the utility model is formed, see also Fig. 2 and shown in Figure 3, it mainly lies in this fin 10 and is provided with a plurality of perforation 11 that supply radiating tube 20 to plug, wherein: each 11 outer rim of boring a hole is provided with through hole 12, use that wear for welding rod 30 can be in order to inject tin cream, flux, this through

hole

12 and 11 of perforation simultaneously maintains suitable distance, and is provided with the spacing arc groove 13 identical with bore a hole 11 aperture unanimities and quantity in fin 10 upper ends.

So as to, make each fin 10 can utilize perforation 11 strings to be located at an end of radiating tube 20, the other end of radiating tube 20 is furnished in the spacing arc groove 13 of each fin 10 upper ends, again welding rod 30 is arranged in the through hole 12, utilize hot melting way simultaneously, make low-melting welding rod 30 produce fusion and form hot melt liquid 31, please cooperate shown in Figure 4 simultaneously, and then utilize hot melt liquid 31 defluent characteristics, make hot melt liquid 31 can be coated on the outer rim of radiating tube 20, and be attached to perforation 11 edges and bore a hole 11 with the fin 10 of 12 of through holes on, increasing the bonding area of fin 10 and radiating tube 20, and then the hot transfer efficiency of 20 of increase fin 10 and radiating tubes.

In other words, characteristics of the present utility model are, be arranged at the outer rim of perforation 11 by through hole 12, and be equipped with low-melting welding rod 30 in through hole 12 inside, utilize hot melting way again, make low-melting welding rod 30 in through hole 12, produce fusion and formation hot melt liquid 31, see through the characteristic that hot melt liquid 31 flows downward, make hot melt liquid 31 be coated on radiating tube 20 peripheries, and be attached to perforation 11 peripheral and bore a hole 11 and the fin 10 of 12 of through holes on, and then the bonding area of increase fin 10 and radiating tube 20, the heat energy that fin 20 is received is sent in the radiating tube 20 smoothly, and utilize radiating tube 20 and air to carry out heat exchange, to increase the efficient of heat radiation.

Moreover, because these fin 10 1 ends are provided with spacing arc groove 13, the perforation 11 of one end of radiating tube 20 and fin 10 is gone here and there establishes, see through the location that spacing arc groove 13 reaches radiating tube 20 simultaneously, radiating tube 20 can effectively be fixed on the fin 10, be unlikely to produce the phenomenon of rocking.
