Description
Technical field
The utility model relates to radiator, relates in particular to a kind of composite radiating module that is applied to heat pipe and radiating fin.
Background technology
The heat dissipation problem of electronic component, be each electronics research and development unit the research and development new product must consider, especially the electronic product function of immediate development is become stronger day by day, volume but dwindles relatively more, so can supply on the space of heat radiation at electronic product, become quite narrow and small, further limit heat dissipation capability.
At present, heat pipe is a kind of design of heat-sinking capability excellence, its external form is the metal pipe of a hollow, two end closures, the inwall of heat pipe adheres to one deck capillary object, soaking working solution in the capillary object, the principle of its application makes the other end when the lower temperature place for the end when heat pipe places the higher temperatures place, the heat transfer phenomenon just begins to produce, this moment heat is at first passed metal pipe-wall by the high temperature place and is entered in the capillary object, working solution in the capillary object start vaporizer that is heated, gas after the evaporation accumulates in the hollow tube of evaporation section, and the low-temperature end towards heat pipe flows simultaneously.
This moment, the other end of heat pipe was positioned at the lower temperature place, when arriving the colder other end, gas just begins condensation, heat is just passed capillary object, working solution and metal pipe-wall and is imported into the lower temperature part by gas at this moment, so the gas that was originally evaporated by evaporation section in the condensation portion has condensed into liquid again, these condensed liquid have flowed back to the metal end of original high temperature because of the effect of capillarity by condensation, and this is the heat conduction principle of heat pipe.
In the known patent documentation, TaiWan, China letters patent book number I255983 number " radiating module and preparation method thereof ", shown in Figure 1 for seeing also, it is the known technology generalized section, all be provided with at least one fixing hole 2 on a plurality of radiating fin devices 1 relatively, this fixing hole 2 also supplies corresponding at least one heat pipe 3 to place, and this heat pipe 3 is provided with a high-termal conductivity coat of metal 4, its high thermal conduction characteristic by this coat of metal 4, the heat energy that makes this heat pipe 3 exhales via being sent on this radiating fin device 1.
Because this radiating fin device 1 that is provided with on this heat pipe 3 is for increasing the purpose of area of dissipation, but such setting, can be made as aluminium matter because of 1 in this radiating fin device, therefore, it is good that the heat absorptivity of this radiating fin device 1 material itself does not have heat dissipating, so form the heat radiation obstacle of this heat pipe 3 easily, moreover, this " radiating module and preparation method thereof " strengthens thermal conduction rate, still for to utilize the setting of this coat of metal 4 on this heat pipe 3, this heat pipe 3 that is provided with this coat of metal 4 is when passing this fixing hole 2, quite easily because the thinner thickness of this coat of metal 4, and cause this coat of metal 4 to be struck off and come off, and then influence heat radiation quality.
Therefore, how further promoting the quality of heat radiation, heat conduction really, is a problem anxious to be improved in fact.
The utility model content
So the purpose of this utility model is to design a kind of composite radiating module that promotes heat pipe and radiating fin heat transfer efficiency.
Based on above-mentioned purpose, the utility model is a kind of composite radiating module, and it comprises: at least one heat pipe, an aluminum radiating fin unit and a bronze medal calendering portion; This aluminum radiating fin unit has at least one radiating fin, and respectively offering at least one perforation respectively on this radiating fin, this perforation wears for this heat pipe, and each this perforation all has a hole wall, and this copper calendering portion presses respectively along being arranged at respectively this radiating fin, and this copper calendering portion coats this hole wall, for this perforation that stretches through of this heat pipe, and this copper calendering portion on this hole wall is directly contacted with this heat pipe.
By technique scheme, the utility model is a kind of composite radiating module, and it has following advantage:
One, enlarges the advantage of area of dissipation in conjunction with the high thermal conduction characteristic of this heat pipe and known radiating fin, and be aided with the design of this copper calendering portion of the utility model and this aluminum radiating fin unit, to pass through the good thermal conductive property of copper, heat with this heat pipe derivation, this copper calendering portion of leading is exhaled by this radiating fin again.
Two, in addition, general known radiator, on the combination process demand of copper and aluminium matter, need doing of aluminium matter nickel, could be when adding tin cream, copper doing with aluminium matter sticked together, yet, in the utility model, make by the calendering formation of this aluminum radiating fin unit and this copper calendering portion, can reduce step and cost that aluminium matter need be changed nickel, therefore, on the one hand the utility model can have aluminium matter and copper high-cooling property and high heat absorptivity separately concurrently, can reduce the processing procedure that aluminium matter need be changed nickel on the other hand, and by this copper calendering portion and the replacement of its calendering formation.

Embodiment
Relevant detailed content of the present utility model and technical descriptioon existing are described further with embodiment, but will be appreciated that, these embodiment are only for illustrating usefulness, and should not be interpreted as the restriction of the utility model enforcement.
See also shown in Figure 2ly, be partial cutaway schematic of the present utility model, the utility model is a kind of composite radiating module, and it comprises: at least one heat pipe 10, an aluminum radiating fin unit 20 and a bronze medal calendering portion 30; This aluminum radiating fin unit 20 has at least one radiating fin 40, and respectively offering at least one perforation 21 respectively on this radiating fin 40, this perforation 21 wears for this heat pipe 10, and each this perforation 21 all has a hole wall 22, and because this copper calendering portion 30 presses respectively along being arranged at respectively this radiating fin 40, make this copper calendering portion 30 coat these hole walls 22,, this copper calendering portion 30 on this hole wall 22 is directly contacted with this heat pipe 10 for this perforation 21 that stretches through of this heat pipe 10.
And the utility model in the use, this heat pipe 10 and a cooling base (not shown) link setting, so that the radiating requirements of an electronic component (not shown) to be provided, in addition, about the binding set-up mode of this copper calendering portion 30 with this aluminum radiating fin unit 20, be mode combination, and make these copper calendering portion 30 calenderings be arranged at this radiating fin 40 1 sides for calendering formation.
See also Fig. 3, Fig. 4-1, Fig. 4-2, shown in Fig. 4-3, be generalized section of the present utility model, the radiating fin front schematic view, radiating fin schematic perspective view and radiating fin diagrammatic cross-sectional side elevation, wherein this aluminum radiating fin unit 20 that wears for this heat pipe 10 has a plurality of these radiating fins 40, yet, each this radiating fin 40 is equipped with this perforation 21, because this radiating fin 40 is and these copper calendering portion 30 calendering formation settings, therefore this copper calendering portion 30 coats the hole wall 22 of this perforation 21, wear for this heat pipe 10, have this perforation 21 in this radiating fin 40, this perforation 21 has this hole wall 22.
