Embodiment
Below in conjunction with accompanying drawing, the utility model is further described: as shown in Figures 1 to 10, a kind of heat radiation module described in the utility model, it comprises some fin 1, heat pipe 2 and base plate 3, " U " type pipe that described heat pipe 2 is inner vacuum, the wall cross-section ovalize of heat pipe 2; Described fin 1 punch forming has oval punching 10; The maximum gauge of the oval tube wall of heat pipe 2 is less than the maximum gauge of the oval punching 10 of fin 1, and the minimum diameter of the oval tube wall of heat pipe 2 is less than the minimum diameter of the oval punching 10 of fin 1; The bottom surface of described base plate 3 offers the arc-shaped slot 30 that circular radian is greater than 1/2 circular arc degree; Described several fin 1 stack formation radiating fin combination, and described heat pipe 2 is through the oval punching 10 of radiating fin combination, and heat pipe 2 inserts the arc-shaped slot 30 of base plate 3 simultaneously with the form of poling.Wherein, to be greater than or to approach 3/4 circular arc degree be optimal case to the circular radian of arc-shaped slot 30.
Further, described fin 1 is aluminium radiator fin, and described heat pipe 2 is copper heat pipe.The coefficient of expansion of aluminium radiator fin and copper heat pipe not etc., can not make the coefficient of expansion surplus of radiating fin combination and heat pipe 2 form and combine closely at binding site when heating.Further, described base plate 3 is aluminium sheet or copper coin, and its heat pipe 2 in inner vacuum at the coefficient of expansion in when heating not etc., can make binding site form and combine closely when heating.Further, the front end of described heat pipe 2 is sealing end 20, and 20 one-tenth of sealing ends are cone-shaped, the cone-shaped oval punching 10 of being convenient to conveniently heat pipe 2 be inserted fin 1.
The production technology of above-mentioned a kind of module that dispels the heat comprises the following steps.
Step 1, makes fin 1, and on fin 1, punch forming has oval punching 10; Several fin 1 are stacked to formation radiating fin combination, and wherein fin 1 is aluminium radiator fin.
Step 2, makes base plate 3, offers the arc-shaped slot 30 that circular radian is greater than 1/2 circular arc degree in the bottom surface of base plate 3; Wherein, to be greater than or to approach 3/4 circular arc degree be optimal case to the circular radian of arc-shaped slot 30.
Step 3, make heat pipe 2, under the secondary process of oil pressure unit, mould, tool, " U " type pipe that is inner vacuum by heat pipe 2 moulding bendings, now the wall cross-section of heat pipe 2 is rounded, by extrusion process, the wall cross-section of heat pipe 2 is processed into ellipse again, and makes the maximum gauge of the oval tube wall of heat pipe 2 be less than the maximum gauge of the oval punching 10 of fin 1, make the minimum diameter of the oval tube wall of heat pipe 2 be less than the minimum diameter of the oval punching 10 of fin 1; Wherein heat pipe 2 is copper heat pipe.
Step 4, due to fin 1 and heat pipe 2, its binding site in the time making is interference fit gap, the oval punching 10 that can easily heat pipe 2 be passed to radiating fin combination, heat pipe 2 tube walls insert the arc-shaped slot 30 of base plate 3 simultaneously with the form of poling.
Step 5, the heat pipe combining 2, radiating fin combination and base plate are fixed by tool, to prevent displacement and loosening, then putting into baking oven heats, in the process heating in baking oven, heat pipe 2 and radiating fin combination are because the impact of high temperature produces thermal expansion in baking oven runner, the coefficient of expansion of heat pipe 2 can be far away higher than the coefficient of expansion of radiating fin combination, in this process due to the coefficient of expansion of radiating fin combination and heat pipe 2 not etc., the coefficient of expansion surplus of radiating fin combination and heat pipe 2 is formed at binding site and combines closely; Not etc. both are not combined closely in formation by heat pipe 2 and base plate 3 thermal coefficient of expansions simultaneously; After heat pipe 2 thermal expansions, its cross section is similar to circle.
Step 6; Take out heat pipe 2, radiating fin combination and base plate after heating, naturally cooling rear formation heat radiation module.
In sum, a kind of heat radiation module described in the utility model, the coefficient of expansion that utilizes aluminium radiator fin and copper heat pipe is not etc., when heating, can make the coefficient of expansion surplus of radiating fin combination and heat pipe 2 form the principle of combining closely at binding site, can greatly simplify the technological process of production, effectively reduce production costs, improve production capacity and product quality.
The above is only preferred embodiments of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
