Abstract
The utility model discloses a connected structure of heat dissipation body and a radiator made by the heat dissipation body. The radiator mainly uses the interface between an aluminum heat dissipation body and a copper heat conductive body. The radiator uses concave convex gnawing combining with regular shape. The concave convex gnawing combining structure between the aluminum heat dissipation body and the copper heat conductive body has a structure which can jam and avoid falling off to make the efficacy of large connection area, large conductive area, high heat dissipating efficiency except for firm and good connection effective between the aluminum heat dissipation body and the copper heat conductive body.
Description
Technical field
The utility model relates to a kind of radiator structure, refers in particular to a kind of connected structure of radiator and the radiator made from this radiator.
Background technology
Because chip can produce high heat in the process of carrying out computing, and the phenomenon of high heat must be got rid of, otherwise will influence the regular event of chip, or even make chip damage; And the high heat that generally produces with the chip computing time gives the mode of quick heat radiating, all is to utilize radiator.
This radiator 1 has an aluminium heat sink body 11 and a copper material heat-conducting seat 12 (see figure 2)s, wherein, the periphery wall of this aluminium heat sink body 11 forms a plurality of radiating fins 111, and this copper material heat-conducting seat 12 is incorporated into the inside of aluminium heat sink body 11, simultaneously at the upright fan of the upper set of this radiator 1; In view of the above, copper material heat-conducting seat 12 can be fixed on the chip top, and paste mutually with chip upper surface and to touch, with the good heat conductivity of utilizing copper material heat-conducting seat 12 to be had, the high heat that produces during the running of fast Absorption chip, simultaneously thermal energy conduction is given aluminium heat sink body 11, and the hot temperature of height is dispelled, reach the purpose of radiating and cooling by the fan of radiator 1 top through this copper material heat-conducting seat 12.
Yet, though aforementioned existing heat spreader structures has utilized properties of materials, and heat sink body is adopted aluminium, heat-conducting seat adopts copper material, in the conduction of heat energy, be different materials just because of aluminium heat sink body and copper material heat-conducting seat, need the aluminium heat sink body to be engaged with the copper material heat-conducting seat by the processing of interface alloying, the aluminium heat sink body is different with the coefficient of expansion of copper material heat-conducting seat simultaneously, therefore when carrying out alloying heat treatment, can cause the composition surface between aluminium heat sink body and copper material heat-conducting seat to fit fully, produce the not good situation of adaptation, and just because of this, make this radiator on the heat radiation conduction efficiency of heat energy, can't reach 100%.
In addition, because this copper material heat-conducting seat belongs to the higher copper product of price, usually the dealer can be with the height reduction of copper material heat-conducting seat for reducing cost, but because of originally limited with aluminium heat sink body contact area, so that the not good situation of pyroconductivity makes the matter worse beyond doubt, thus the existing heat spreader structures of this kind can't reduce cost and high heat conduction efficiency between obtain the good effect that has concurrently.
In addition, still visible on the market another kind of radiator 2 structures, it improves aforementioned radiator 1 can't reach 100% disappearance on the heat radiation conduction efficiency of heat energy, structure such as Fig. 1 of this radiator 2 show that it is formed by the aluminium heat sink body 21 and the copper material heat-conducting seat 22 of unlike material equally; Wherein, form a plurality of radiating fins 211 in the upper surface of this aluminium heat sink body 21, its lower end then is bonded into one with interface Alloying Treatment mode and copper material heat-conducting seat 22, and both 23 on composition surfaces of aforementioned aluminium heat sink body 21 and copper material heat-conducting seat 22 form zigzag or wavy concaveconvex structure, to utilize the concaveconvex structure increase contact area between the two on composition surface 23.
Promptly suppose aluminium heat sink body 11 and 12 1.8 times of contacting area of copper material heat-conducting seat that it can increase aforementioned radiator 1, represent that then it can increase the radiating effect of 1.8 times in this radiator, to produce adaptation not good to compensate aforementioned radiator 1 composition surface of 12 of aluminium heat sink body 11 and copper material heat-conducting seats after carrying out alloying heat treatment, and pyrogenicity can the bad defective of heat radiation conduction efficiency.
In the enforcement of reality, though this radiator 2 that developed design afterwards can improve the heat dissipation of the most traditional aforementioned radiator 1, but, as preceding described, this radiator 2 is still by aluminium heat sink body 21 and copper material heat-conducting seat 22 and is formed, so it when carrying out interface alloying heat treatment, is understood equally because aluminium heat sink body 21 is different with the coefficient of expansion of copper material heat-conducting seat 22, and in the not good defective of the adaptation that produces the gap each other, so its radiating efficiency still remains to be improved; Especially there is no any means that will fix really each other between aluminium heat sink body 21 and the copper material heat-conducting seat 22, so therefore the aluminium heat sink body 21 of carrying out after the alloying heat treatment may separate with copper material heat-conducting seat 22.
The design is still remained to be improved on heat dissipation by aluminium heat radiation lamellar body and the formed radiator of copper material heat-conducting seat in view of existing, so the utility model is developed in assisting a ruler in governing a country of the professional knowledge of being accumulated by itself, technology.
