The CPU heat abstractor that present industry is used is to adopt heat-conducting block, heat radiator, radiator fan mostly, heat-conducting block transfers heat to heat radiator, by radiator fan, heat radiator being absorbed heat dispels, but the radiating efficiency of this heat abstractor still is restricted, and has the problem that radiating rate is slow, heat radiation is insufficient, radiating effect is relatively poor.
The utility model content
The purpose of this utility model is to provide a kind of efficient radiating apparatus of computer CPU, effectively solves the problem that the heat abstractor radiating rate is slow, radiating effect is poor of the CPU of active computer.
the technical solution adopted in the utility model is: comprise the contacted heat-conducting block with CPU, at least two chip heat radiator, the first radiator fan, also comprise at least two heat pipes that are arranged in parallel, at least two radiated ribs that are arranged parallel to each other, the second radiator fan, be provided with on heat-conducting block top with each heat pipe is corresponding respectively and laterally be parallel to each other, at least two tube seats, the evaporation ends correspondence of each heat pipe is fixedly installed in each tube seat, the colling end of each heat pipe all passes each radiated rib successively, and be fixedly connected with each radiated rib, heat transfer medium all is housed in each heat pipe, at least two chip heat radiator are parallel to each other and vertically are arranged in each above tube seat, in each chip cooling sheet upper horizontal, the first radiator fan is installed, vertically is provided with the second radiator fan between the outside of outermost radiated rib and case radiation air outlet inboard.
For guaranteeing fixed effect preferably, and be conducive to heat radiation, the evaporation ends of each heat pipe is bonded in each tube seat by the heat conductive silica gel correspondence.
For guaranteeing fixed effect preferably, and be conducive to heat radiation, pass through heat conductive silica gel between the colling end of each heat pipe and each radiated rib bonding.
Stable for ensureing, efficient radiating efficiency, heat pipe adopt constant temperature controllable type heat pipe.
Has the coefficient of heat conductivity that obviously is better than common fluid because of nano-fluid, for ensureing higher heat transfer efficiency, the fluid media (medium) that heat transfer medium is comprised of water and ferroferric oxide nano granules.
Good effect of the present utility model is: adopt " heat pipe " element, namely fill with heat transfer medium and utilize the decalescence of heat transfer medium and the high efficient heat exchanging element that heat interchange is carried out in heat release in the shell of sealing, hot pipe technique takes full advantage of the Rapid Thermal hereditary property of heat-conduction principle and heat transfer medium, be delivered to rapidly outside thermal source through the heat of heat pipe with thermal objects, play the rapidly and efficiently effect of refrigeration.The utility model one-piece construction is simple, reasonable in design, on the one hand by chip cooling sheet, radiator fan heat radiation, rely on the other hand the phase transformation of inside heat pipe heat transfer medium to realize conducting heat, heat-transfer capability is strong, reliable, noiselessness, the more heats of large conduction of can trying one's best in limited room and time, have that radiating efficiency is high, rapid heat dissipation, characteristics that environmental suitability is strong, can satisfy the heat radiation requirement of high-performance computer CPU, make CPU can stablize, work.
