Description
[technical field]
The utility model relates to a kind of heat abstractor of chip module.
[background technology]
Development along with Information technology, the for example enhancing of computer function, deposit the expansion of Chu device energy etc., the function of various chip modules is also in continuous enhancing, the processing mode that is chip module just develops towards the direction of high-frequency high-speed, yet the heat that high-frequency high-speed will make chip module produce when work is more and more, temperature is also more and more higher, the stability of chip module operation in serious threat, for guaranteeing the normal operation of chip module energy, needs dispel the heat to it.
And the heat abstractor of original chip module, a kind of calculator memory bar fin (referring to this patent Fig. 1 and Fig. 2) is disclosed as Chinese patent CN200520068258 number, comprise a slim heat sink body 1, at least one fastener 2, wherein, the joint end 3 of this fastener 2 is " T " font, then be provided with and be somebody's turn to do the open slot 4 that " T " font joint end is complementary on the described heat sink body 1, this open slot 4 is made of two boss 5 on the described heat sink body 1, this two boss 5 forms a shoulder 6 that extends in opposite directions respectively with an end of described fastener 2 clampings, described " T " font joint end 3 is provided with a neck 7, the opening that this neck 7 just can place described two shoulders 6 to form.The shoulder 6 that " T " font joint end 3 of described fastener can effectively be extended by described two boss 5 in opposite directions blocks, and unlikely coming off can be described as the method for reverse deduction of circling round, load onto memory bar after, described heat sink body 1 is not rebounded with tight contact of described memory bar.
But now, continuous enhancing along with the chip module function, the heat that produces during its work is more and more, temperature is also just more and more higher, requirement to radiating effect is also more and more higher, disclose a kind of heat abstractor 200 (referring to this patent Fig. 1 and Fig. 2) of electronic installation for No. 5969946 as U.S. Pat, comprised an electric connector 10, a sub-circuit board 20, a radiator 30 and at least one fixation kit 40.Wherein, this fixation kit 40 comprises a support column 41 and two bolts 43,44, described electric connector 10 is installed on the substrate 99, which is provided with an inserting groove 11, can peg graft for above-mentioned sub-circuit board 20, this sub-circuit board 20 is provided with a plurality of electronic installations 21, above-mentioned radiator 30 is installed on this electronic installation 21, this radiator 30 also has a plurality of fin 34,35, and wherein at least one described fin 35 is provided with a fixed part 36, described support column 41 is arranged between described substrate 99 and the described fixed part 36, described support column 41 locks on substrate 99 by described bolt 44, described radiator 30 locks on described support column 41 by described bolt 43 by its fixed part 36, and then is fixed on the described substrate 99, because this support column 41 can support the weight of described radiator 30, and described radiator 30 locks on described support column 41 by described bolt 43, therefore, the weight of described radiator 30 can not cause turning moment or cause vibrations, and described sub-circuit board 20 is become flexible.
