Compared with prior art, the invention embeds a muffle in the through holes, the heat radiation fins are combined with heat pipe indirectly via the muffle, to resolve the defects of direct combination between the heat radiation fins and heat pipe.
Description
Technical field
The present invention relates to a kind of heat abstractor, particularly a kind of radiating fin makes up and uses the heat abstractor of this radiating fin combination.
Background technology
The high power electronic element needs heat abstractor to dispel the heat in running, existing heat abstractor generally includes the radiating fin of parallel interval arrangement and is placed through heat pipe in the radiating fin, with by the high thermal conductivity of heat pipe with the heat transferred radiating fin that electronic component produces, by radiating fin heat is dispersed in the surrounding air.
Radiating fin directly combines with heat pipe usually, but both are directly in conjunction with existing some shortcomings.For example, when heat pipe is that copper material is made, and radiating fin is when adopting aluminium material to make based on the consideration of cost and weight, because the welding performance of aluminium is relatively poor, both are when welding, need earlier aluminium matter fin to be carried out the nickel plating surface treatment, and this surface treatment procedure has increased the production cycle, has improved production cost.
Summary of the invention
In view of this, be necessary to provide a kind of improved radiating fin to make up and use the heat abstractor of this radiating fin combination.
A kind of radiating fin combination, comprise the radiating fin that has perforation and be embedded at sleeve in the described perforation, described sleeve comprises a tubular body and a flange that goes out from this tubular body ora terminalis radial expansion, described tubular body is embedded in the described perforation, and described flange is close to a side of described radiating fin.
A kind of heat abstractor, comprise radiating fin combination and heat pipe, the combination of described radiating fin comprises the radiating fin that has perforation and is embedded at sleeve in the described perforation, described heat pipe is placed through in the described sleeve, described sleeve comprises a tubular body and a flange that goes out from this tubular body ora terminalis radial expansion, described tubular body is embedded in the described perforation, and described flange is close to a side of described radiating fin.
The present invention compared with prior art owing to set sleeve in the perforation of radiating fin, radiating fin combines with heat pipe indirectly by sleeve, can solve the some shortcomings that radiating fin and heat pipe directly combine.For example, in the perforation of aluminium matter fin, set copper sleeve,, thereby need not aluminium matter fin is carried out the nickel plating surface treatment by sleeve and heat pipe welding.
The invention will be further described below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the constitutional diagram of the radiating fin combination in the one embodiment of the invention.
Fig. 2 is the exploded view of radiating fin combination shown in Figure 1.
Fig. 3 be among Fig. 1 III-III to cutaway view.
Fig. 4 is a structural representation of using the heat abstractor of radiating fin combination shown in Figure 1.
Embodiment
Fig. 1 to Fig. 3 shows an embodiment of radiating fin combination 1 of the present invention, this radiating fin combination 1 can cooperate formation one heat abstractor (as shown in Figure 4) with heat pipe 2, it comprises and has perforation 13 radiating fin 10 and be embedded at sleeve 20 in this perforation 13, but perforation 23 heating tubes 2 of sleeve 20 place.
Radiating fin 10 (for example adopts the good material of heat conductivility, aluminium) make, it comprises that one is flat fin body 11 substantially, fin body 11 respectively is formed with a perforation 13 near the both side edges place, and the shape of perforation 13 can be arbitrary shapes such as circle, ellipse according to the cross sectional shape of heat pipe 2.One side of fin body 11 protrudes out a ring edge 15 around perforation 13, and ring edge 15 can increase the contact area of fin body 11 and sleeve 20 on the one hand, can improve the bond strength of fin body 11 and sleeve 20 on the other hand.
The material that sleeve 20 can adopt heat conductivility and/or welding performance to be better than radiating fin 10 is made (for example, copper or silver), and it comprises a tubular body 25 and a flange 21 that goes out from the 25 ora terminalis radial expansions of tubular body.Tubular body 25 overall dimensions 13 adapt with perforation, so that it is when being embedded in the perforation 13, its outside wall surface closely is matched with the inner edge of perforation 13.The flange 21 of sleeve 20 closely fits in the side of fin body 11, is used to increase the contact area of sleeve 20 and fin body 11, thereby improves thermal conductivity between the two.Preferably, can fill an amount of heat-conducting glue between flange 21 and the fin body 11, with further raising thermal conductivity therebetween.Sleeve 20 can be by easily realizing towards modes such as riveting or interference fit and the combining closely of radiating fin 10, and the radiating fin 10 that has a sleeve 20 is simplified (for example, aluminium matter radiating fin need not nickel plating) with combining also of heat pipe, and guarantee heat transfer efficiency.
In radiating fin combination 1, sleeve 20 adopts modes such as interference fit or riveted joint to be incorporated on the radiating fin 10, and can adopt and make towards the method for machinings such as riveting, for example, it can adopt following steps to make: (1) provides first sheet material and second sheet material, and first sheet material is aluminium matter, be used for as the raw material of making radiating fin 10, second sheet material is copper or silver, is used for as the raw material of making sleeve 20, and the size of second sheet material can be much smaller than first sheet material; (2) second sheet material is positioned over the precalculated position of the first sheet material side, and carry out piercing and flanging along the method vertical with first sheet material over against second sheet material, the flange (body 25 of corresponding sleeve 20) of second sheet material closely is embedded in the perforation (annular distance 13 of corresponding radiating fin 10) of first sheet material, first sheet material and second sheet material closely are riveted together, promptly finish the manufacturing of radiating fin combination 1.
Fig. 4 shows the heat abstractor that has radiating fin combination 1, this heat abstractor can be used for distributing the heat that electronic component such as computer cpu produces, it comprises some radiating fin combination 1 and two heat pipes 2 that are arranged in parallel, the heat unit of heat pipe 2 is arranged in the sleeve 20 of radiating fin combination 1, and welds together with sleeve 20.This heat abstractor in the course of the work, the endothermic section of heat pipe 2 absorbs heat from electronic component, and from heat unit with heat transferred to sleeve 20, by sleeve 20 heat is conducted to radiating fin 10, by radiating fin 10 heat is dispersed in the surrounding air again and goes, thereby realized cooling electronic component.Follow according to needs, this heat abstractor can also add other elements such as substrate and fan; The quantity of heat pipe 2 can be one or more, and its shape can take the shape of the letter U or S shape etc.
