Description

The heat radiation module

Technical field

The utility model relates to field of mechanical technique, particularly a kind of heat radiation module.

Background technology

Progress along with semiconductor technology, the volume of integrated circuit also dwindles gradually, and in order to make integrated circuit can handle more data, integrated circuit under the equal volume, can hold than Duoed the upward element more than the several times in the past, when the number of elements in the integrated circuit is more and more, the heat energy that is produced during element work is also increasing, with common central processing unit is example, when the fully loaded workload of height, the temperature that central processing unit gave out is enough to make that central processing unit is whole burns, therefore, the heat abstractor of integrated circuit becomes important problem.

And general radiator is made through the metal material of high thermal conductivity coefficient mostly, simultaneously in order to improve radiating effect, come the heat extraction except installing fan additional, the kenel that is set to fins group mostly cooperates heat radiation, further see through heat pipe and quicken to get rid of heat energy, burn to prevent the integrated circuit product.

As Fig. 1, shown in 2, schematic perspective view and front view for prior art heat radiation module, the heat radiation module 1 of prior art has a radiating fin group 11 as shown in the figure, a plurality of heat pipes 12 and a pedestal 13 are formed, described radiating fin group 11 is made up of a plurality of radiating fin 11A and described radiating fin group 11 has a heat-conducting part 111 and a radiating part 112, described heat-conducting part 111 and radiating part 112 offer a plurality of holes 113, described heat pipe 12 has a heat conduction end 121 and a radiating end 122, and be arranged in the heat-conducting part 111 of described radiating fin group 11 and the hole 113 that radiating part 112 is offered respectively, combine with described radiating fin group 11, the end that described radiating fin group 11 has heat-conducting part 111 engages with described pedestal 13, see through that described pedestal 13 combines with a heat-generating units 2 and the thermal source of described heat-generating units 2 is conducted to the heat-conducting part 111 of described radiating fin group 11 and the heat conduction end 121 of heat pipe 12, by described heat pipe 12 thermal source is dispelled the heat by the radiating part 112 that radiating end 122 passes to described radiating fin group 11 again, prior art only sees through heat pipe 12 and quickens the conduction of thermal source, but fully effectively thermal source is not conducted to really the radiating fin outside than the cold junction place, cause the central interior thermal source of heat radiation module to continue to heat and effectively to get rid of, so make traditional heat radiation module 1 can't bring into play its due heat dissipation, in addition, heat pipe 12 must be bent to form a bend 123 and have a radius of curvature when establishing because of 11 groups of heat pipe 12 and radiating fin groups in the heat radiation module 1 of prior art, if will being damaged, the conductive structure (not shown) the when radius of curvature of described heat pipe 12 bends 123 is too small in the then described heat pipe 12 make described heat pipe 12 lose usefulness, so the area that needs to increase radiating fin group 11 fins is established with the group that cooperates heat pipe 12, but along with described radiating fin group 11 areas increase and the increase of heat pipe 12 bends 123 radius of curvature increase order heat radiation module 1 entire area, when being arranged at, described heat radiation module 1 then can occupy in the described electronic equipment (not shown) too much space when carrying out auxiliary heat dissipation in the electronic equipment (not shown), therefore how can properly combine again with the heat pipe collocation with radiating fin group than small size, to obtain preferable radiating effect, be the problem that will actively solve at present.
