Abstract

The utility model relates to a structure improved cooling fin, and comprises a base and a plurality of heat dissipation fins positioned along the base. A clamping part with deformation space is arranged between the space of the base and a plurality of heat dissipation fins. After the clamping part is sheathed with a heat conduction pipe, the utility model makes use of a tool to squeeze the clamping part and the heat conduction pipe at the same time, thereby making the clamping part deform towards the deformation space and clamping the heat conduction pipe; the tool can directly form a deformation part on the heat conduction pipe; the deformation part make the tube wall of the heat conduction pipe expand outward and press on the inner wall of the clamping part. Thus, when the cooling fin is under operation, the heat conduction pipe can be closely arranged inside the clamping part of the heat dissipation fin and form a non-clearance state between the heat dissipation fin and the base, ensuring the heat in the base of the heat dissipation fin can be rapidly conducted.

Description

Structure improved fin

Technical field

The utility model relates to a kind of structure improved fin, refers to a kind of fin that heat pipe can be combined closely by instrument especially.

Background technology

Progress along with the technology growth and the manufacture of semiconductor of integrated circuit, the electronic circuit that early stage many circuit that present with the electronic component kenel or a plurality of integrated circuit link mutually, produce towards the mode of integrated integrated circuit one after another, also refer to include more function in the integrated circuit, and instruction and the signal that can handle more complexity.

And the integrated circuit under certain volume, when the electronic component that inside comprised, as FET, numbers such as COMS more for a long time, the heat energy that is distributed during its work also improves relatively, early stage integrated circuit, as central processing unit etc., fin only need be installed just to be enough to heat energy is shed, and integrated circuit in recent years, central processing unit particularly, except fin was installed, the fan of heat transmission had become the device that must install, fin all is connected on the integrated circuit with the base portion of bottom, by radiating fin on the base portion and fan heat energy is derived, still have a segment distance between right fan and fin base portion, so the heat energy that base portion absorbs can't conduct the end (that end that promptly is connected with fan) that causes radiating fin apace, so most heat energy still is accumulated in the base portion of fin, and the efficient that causes dispelling the heat reduces.

And more improve for the efficient that makes heat radiation, so have manufacturer to develop to have the heat abstractor of heat pipe, as the TW patent gazette, No. 9 74, notification number M252, title: the radiating module of using multiple tubular type heat-transfer superconductive pipe heat conduction, as shown in Figure 8, be existing fin three-dimensional exploded view, be drilled with a plurality of hole A11, A21 on the sidewall of finding out fin A1, A2 by knowing among the figure, be inserted in respectively with two ends in a plurality of hole A11, the A21 of sidewall of fin A1, A2 heat pipe A3 so that fin A1 with thermal energy conduction to other fin A2.

Right above-mentioned fin still has following defective in use:

When (one) fin A1, A2 combine with heat pipe A3, only two ends of heat pipe A3 are inserted in hole A11, the A21 of sidewall of fin A1, A2, when fin A1, A2 combine with radiator fan and are used in circuit board, owing to can produce vibration during fan running, and vibrations are reached on fin A1, the A2, then also vibrations thereupon of heat pipe A3, under long-term vibration, the phenomenon that heat pipe A3 is easy and fin A1, A2 generation gets loose.

(2) fin A1, A2 are provided with hole A11, A21 in sidewall, though can plant for heat pipe A3, right heat pipe A3 only inserts in hole A11, the A21 with the fore-end of two ends, so heat pipe A3 only can conduct fin A1, the A2 part heat energy on the sidewall of bottom, and can't effectively conduct near bottom center heat energy partly, and the efficient of heat radiation is reduced.

So, how to solve above-mentioned prior art problems and defective, be the design people and desire most ardently the direction place that research improves with the relevant manufacturer that is engaged in the industry.

Summary of the invention

Main purpose of the present utility model is to overcome the deficiencies in the prior art and defective, a kind of structure improved fin is proposed, this fin is provided with clamping part in base portion, and clamping part is provided with deformation space, be arranged in the clamping part of fin when heat pipe after, instrument via machine punching press or utensil punching press, while press nip and heat pipe, make clamping part toward the deformation space displacement, and but pinching is sheathed on the heat pipe in the clamping part, and heat pipe is subjected to being formed with variant part after machine punching press or the utensil punching press, and the tube wall of heat pipe is expanded outwardly, and urgent in the inwall of clamping part, thus, when fin in use, heat pipe can closely be fixed in the clamping part of fin, and can and the base portion of fin between form no gap state, the heat energy of the base portion of fin can be conducted fast, and fin is in the process of transporting or being installed on circuit board, and heat pipe will can not produce and come off.

For reaching above-mentioned purpose, the utility model provides a kind of structure improved fin, especially refer to a kind of fin that the heat energy of heating object can be discharged, this fin has base portion, a plurality of radiating fins on base portion, have been extended, and extended clamping part between base portion and a plurality of radiating fin, be arranged with heat pipe in the clamping part, wherein, this clamping part cuts open to be provided with and can utilize instrument to make clamping part form the deformation space of the sheathed heat pipe of pinching, and heat pipe is provided with the variant part that a tube wall that can make heat pipe expands outwardly.
