Description

Fin
Technical field
This utility model relates to the accessory of small electronic equipment, relates to a kind of fin.
Background technology
In the middle of micromodule equipment, owing to equipment integral thickness is relatively thin, cause the volume ratio of fin relatively Little, often do not reach preferable radiating effect, the solution for this technical staff now is Fall fin directly heat generating component to be transformed, although this method can solve heat dissipation problem, but It is that production process is loaded down with trivial details, adds the manufacturing cost of micromodule equipment.
Utility model content
For solving above-mentioned technical problem, we have proposed a kind of fin, its purpose: meet miniature The thickness requirement of equipment, and without heat generating component is transformed, improve radiating efficiency.
For reaching above-mentioned purpose, the technical solution of the utility model is as follows:
A kind of fin, including main body, blade and heat pipe, the end face of main body is provided with draw-in groove, Blade end is provided with fixture block, and blade assigns into the top of main body by the cooperation of fixture block and draw-in groove, main Copper sheet it is provided with between body and blade;
It is circular arc that blade protrudes from the part of body top;
Heat pipe includes the radiating end of hollow, the changeover portion of hollow and the collecting end of heat of hollow, radiating end, Changeover portion and collecting end of heat form an annular seal space closed after being interconnected, be provided with copper powder in annular seal space Layer, and in annular seal space, it is marked with coolant;
In the vertical direction radiating end location is less than collecting end of heat location;
The bottom of main body is connected with the top of radiating end, and the bottom of collecting end of heat is connected with heat generating component;
The sidepiece of main body is provided with screw corresponding with fixed mount.
By technique scheme, radiating end, changeover portion and collecting end of heat form one after being interconnected The annular seal space closed, is provided with copper powder layer, and is marked with coolant in annular seal space, work as thermal-arrest in annular seal space When end is heated, in collecting end of heat, the coolant of copper powder layer can become gas, diffuses to radiating end, radiating end Gas is cooled to liquid, during then liquid coolant can be along copper powder layer moistening to collecting end of heat, with This carries out quick heat radiating, improves radiating efficiency, and the position residing in the vertical direction radiating end Setting low in collecting end of heat location, the bottom of main body is connected with the top of radiating end, collecting end of heat Bottom be connected with heat generating component, effectively reduce the height needed for this fin, meet miniature The thickness requirement of equipment, and without heat generating component is transformed.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, in this utility model embodiment Technical scheme is clearly and completely described, it is clear that described embodiment is only this practicality Novel a part of embodiment rather than whole embodiments.Based on the embodiment in this utility model, The every other reality that those of ordinary skill in the art are obtained under not making creative work premise Execute example, broadly fall into the scope of this utility model protection.
Below in conjunction with schematic diagram, detailed description of the invention of the present utility model is made further details of theory Bright.
Embodiment 1.
As shown in Figure 1 and Figure 2, a kind of fin, including main body 1, blade 2 and heat pipe, main The end face of body 1 is provided with draw-in groove 11, and blade 2 end is provided with fixture block 21, and blade 2 passes through fixture block 21 and the cooperation of draw-in groove 11 assign into the top of main body 1, be provided with copper between main body 1 and blade 2 Sheet 3, copper sheet 3 i.e. prevents blade 2 to rock, and by main body 1, heat can be transferred to blade 2 again On.
It is circular arc that blade 2 protrudes from the part at main body 1 top, i.e. increases the surface of blade 2 Long-pending, accelerate heat radiation, reduce again taking up room of this fin.
Heat pipe includes the radiating end 121 of hollow, the changeover portion 122 of hollow and the collecting end of heat of hollow 123, radiating end 121, changeover portion 122 and collecting end of heat 123 form a closing after being interconnected Annular seal space 4, is marked with coolant in being provided with copper powder layer 5, and annular seal space 4, works as thermal-arrest in annular seal space 4 When end 123 is heated, in collecting end of heat 123, the coolant of copper powder layer can become gas, diffuses to radiating end 121, gas is cooled to liquid by radiating end 121, and then liquid coolant can be along copper powder layer moistening To collecting end of heat 123, carry out quick heat radiating with this, improve radiating efficiency.
In the vertical direction radiating end 121 location is less than collecting end of heat 123 location, The bottom of main body 1 is connected with the top of radiating end 121, the bottom of collecting end of heat 123 and heating group Part is connected, and effectively reduces the height needed for this fin, meets the thickness requirement of micromodule equipment, And without heat generating component is transformed.
