Description
Technical field
The utility model refers in particular to a kind of radiator of composite relevant for radiator.
Background technology
Because chip can produce high heat in the process of carrying out computing, and high thermal phenomenon must be got rid of, otherwise will influence the regular event of chip, even makes 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.
Figure 1 shows that a kind of known radiator, this radiator 1 has an aluminium heat sink body 11 and a copper material heat-conducting seat 12, wherein, form most radiating fins 112 on the base portion 111 of aluminium heat sink body 11, and copper material heat-conducting seat 12 is incorporated into base portion 111 bottoms of aluminium heat sink body 11, simultaneously at the upright fan of the upper set of radiating fin 112; In view of the above, copper material heat-conducting seat 12 can be fixed on chip 10 tops, and paste mutually with chip 10 upper surfaces and to touch, to utilize copper material heat-conducting seat 12 to have good heat conductivity, the high heat that produces during 10 runnings 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 aluminium heat sink body 11 tops through this copper material heat-conducting seat 12.
Yet, though the known radiator of this kind is in response to the characteristic of material, and adopt aluminium, heat-conducting seat to adopt copper material heat sink body, the subsides that just are face between aluminium heat sink body and the copper material heat-conducting seat touch the state of closing, contact area each other and interface alloying engage finite volume, cause heat conducting efficient also therefore to be had a greatly reduced quality.
Please consult shown in Figure 2 again, be the known radiator 2 of another kind, radiator 2 has an aluminium heat sink body 21 and a copper material heat-conducting seat 22, wherein, the periphery wall of aluminium heat sink body 21 forms most radiating fins 211, and copper material heat-conducting seat 22 is incorporated into the inside of aluminium heat sink body 21, simultaneously at the upright fan of the upper set of radiator; In view of the above, copper material heat-conducting seat 22 can be fixed on the chip top, and paste mutually with chip upper surface and to touch, to utilize copper material heat-conducting seat 22 to have good heat conductivity, the high heat that produces during the running of fast Absorption chip, simultaneously thermal energy conduction is given aluminium heat sink body 21, and the hot temperature of height is dispelled, reach the purpose of radiating and cooling by the fan of radiator top through this copper material heat-conducting seat 22.
