Description

Heat-pipe radiator and fin thereof

Technical field

The utility model relates to a kind of heat-pipe radiator and fin thereof, relates in particular to a kind of being located on the electronic heating component, but the outside of opposite heat tube forms pulling effect of elastic clip, with the increase respectively heat-pipe radiator and the fin thereof of the fixing tightness of this fin and heat pipe.

Background technology

Progress along with Information technology and computer industry, the caloric value of electronic building brick such as central processing unit chip, internal memory is more and more high, and size is more and more little, for the heat that this is intensive is dispersed in the environment outside the system effectively, keep the following operation of assembly in permissive temperature, usually be attached on the electronic building brick surface of heating with fin, or, increase its overall radiating efficiency to increase the rotating speed of radiator fan with big base area; So, will derive relevant issues such as noise, weight, cost and system complexity, make that above-mentioned respectively this scheme is not the good plan that solves the electronic building brick heat radiation.

At present aspect the heat radiation of electronic heating component, utilize heat pipe to have characteristics such as high capacity of heat transmission, flash heat transfer, high thermoconductivity, in light weight, simple in structure and multipurpose, can transmit a large amount of heat and not consume electric power, therefore be fit to very much the radiating requirements of electronic product; So heat pipe in conjunction with the formed heat-pipe radiator of fin, has been become the important topic that solves heat radiation.

Known heat-pipe radiator structure mainly comprises: a plurality of fin and heat pipe.Each fin has the en plaque body, offers a plurality of perforation in the centre of this body.Stretch out at the periphery of each perforation and to be provided with flange, the inner edge shape of this flange is greater than the outer rim shape of heat pipe, and be coated with heat-conducting medium at the internal face of each flange or the outer surface of heat pipe, during combination with heat pipe concatenation in the perforation of each fin, with the hot melting mode of heating, be combined into heat-pipe radiator again.

Yet, above-mentioned known heat-pipe radiator, because the flange inner wall shape of each fin is greater than the outer rim shape of heat pipe, certainly will between the contacting of said two devices, be coated with the low melting point heat-conducting medium, so will increase heat-conducting medium coating, the manufacturing cost of hot melt operation and the use cost of material.Secondly, the assembling process in by avoiding the perforated inwall of heat-conducting medium to be struck off, will strengthen the inner edge radius of this perforation, but when the outer rim shape difference distance of inner edge shape of boring a hole and heat pipe is excessive, to make the long-pending more minimizing of heat pipe and each fin direct contact surface, and behind a large amount of coated with thermally conductive media, the thermal conduction rate of this heat-conducting medium is far below the thermal conduction rate of heat pipe or fin, and makes the radiating efficiency of this heat-pipe radiator and heat pass poor effect.

So, the design people is in view of the defective that exists in the above-mentioned prior art, rely on the sector experience for many years of being engaged in, and at the problem points that can improve, be to concentrate on studies and cooperate actual utilization, in line with excelsior spirit, propose a kind of reasonable in design and effectively improve the utility model of the problems referred to above point finally.

The utility model content

Main purpose of the present utility model is to provide a kind of heat-pipe radiator and fin thereof, it utilizes the flange ring body to have the inner edge diameter of different sizes, but the outside of opposite heat tube forms the elastic clip effect of pulling, increasing the fixing tightness of each fin and heat pipe, thereby the heat that improves heat-pipe radiator passes effect and radiating efficiency.

To achieve these goals, the utility model provides a kind of heat-pipe radiator and fin thereof, this heat-pipe radiator comprises: a plurality of fin and at least one heat pipe, wherein respectively this fin has the en plaque body, on this body, offer at least one perforation, stretch out at this perforation periphery and to be formed with flange, this flange is the closed ring body, the centre that axially is of this ring body inwardly concaves, and the shape that two ends expand outwardly, and an end of this heat pipe is arranged in the perforation of this fin respectively, and is the respectively folded socket of pulling of this flange ring body, thereby realizes above-mentioned purpose.

Embodiment

Relevant feature of the present utility model and technology contents see also following detailed description and accompanying drawing, and accompanying drawing only provides reference and explanation, is not to be used for the utility model is limited.

Fig. 1 is the stereoscopic figure of fin of the present utility model; Fig. 2 is that the partial enlarged drawing of A part among Fig. 1 reaches; Fig. 3 is the local amplification view of fin.The utility model provides a kind of heat-pipe radiator and fin thereof, and as Fig. 1, Fig. 2 and shown in Figure 3, this heat-pipe radiator comprises: a plurality of fin 1 and at least one heat pipe 2 (as shown in Figure 4), wherein:

Fin 1 is made with aluminium, copper or other thermal conductivity good metal material, and it has en plaque body 11.On body 11, offer at least one perforation 12, in the present embodiment, offer four perforation, stretch out and be formed with flange 13 at perforation 12 peripheries, flange 13 is the closed ring body, and the centre that axially is of this ring body inwardly concaves the shape that two ends expand outwardly, and it can be arc, taper or other various geometry, and present embodiment is the arc ring body.Left and right two ends at body 11 are formed with breach 14 respectively, upwards are bent with flanging 15 at breach 14 root edges.Be provided with a plurality of rectangular through-hole 16 in the centre of body 11, on a side direction of through hole 16, be bent with barricade 17, thus, make 1 of adjacent fin paste butt mutually and touch, and be formed with the heat radiation runner of equi-spaced apart; Moreover the height of flanging 15 and barricade 17 is lower than the ring body height of flange 13, the compression when making up to reserve heating tube 2.

Fig. 4 and Fig. 5 are respectively the assembling schematic diagram and the combination enlarged drawing of the utility model fin and heat pipe.As Fig. 4 and shown in Figure 5, wherein, heat pipe 2 is serially connected on each fin 1, and its inside has capillary structure and working fluid, and heat pipe 2 has heating end 21 and condensation end 22.Heating end 21 is used for attaching mutually with electronic heating component and contacts, and the outer rim shape of condensation end 22 is greater than the minimum inner edge shape of flange 13 ring bodies of each fin 1, but so that the ring body elastic clip of each flange 13 pull on the condensation end 22 of heat pipe 2.

During assembling, each heat pipe 2 is vertically set in platform or the anchor clamps, and the condensation end 22 that makes heat pipe 2 up, order is socketed in each fin 10 on the condensation end 22 again, with default pressing element the flange 13 of each fin 10 is imposed the pressing operation again, the ring body of flange 13 is produced to internal condensation, be retained on the condensation end 22 of heat pipe 2, be combined into heat-pipe radiator thereby tighten.Owing to inwardly concave in the middle of flange 13 is, and the closed ring body that two ends expand outwardly, be easy to by 10 sockets of each fin, and the ring body of military order flange 13 produces strain in the process of being inserted in, and reduce the friction loss of heat pipe 2 and flange 13 inwalls, and the condensation end 22 of can elastic clip pulling and being retained on heat pipe 2; Thus, can save known heat-conducting medium coating, the manufacturing cost of hot melt operation and the use cost of material, more can increase the heat conduction usefulness and the radiating efficiency of heat-pipe radiator.
