Abstract

The water-cooling head comprises a porosity minitype flow passage structure. A first cap and a second cap form a water-cooling head; from two ends of the first cap respectively extends an intake water pipe and a outtake water pipe; in the second cap there is a porosity minitype flow passage made by sintering the powder with heat conduct. The lateral surface of the second cap has a touching surface for absorbing the heat source and transmitting the heat source to the porosity minitype flow passage structure in order to make the cooling liquid into the water-cooling head from the intake water pipe; the porosity minitype flow passage produces disturbed flow function that delay the time of cooling liquid in the water-cooling head so as to produce sufficient heat exchange between the cooling liquid and the porosity minitype flow passage structure.

Description

Water-cooled radiating structure and preparation method thereof
Technical field
The present invention relates to a kind of water-cooled radiating structure and preparation method thereof, particularly a kind of water-cooled head that is applicable to electronic building brick and preparation method thereof.
Background technology
The running of any electric equipment, all generations of the heat that can be difficult to avoid too much because of efficient or friction problem, production development in science and technology industry now tends to accurate more especially, as integrated circuit, the personal electric product, except the volume miniaturization, the generation of its heat also gets over increase, especially in computer, because the continuous lifting of its operation efficiency, make the whole caloric value of computer also increase thereupon, and the main heating source of computer no longer is confined to CPU, and other is such as chip module, Graphics Processing Unit, therefore the contour quick-mounting of Dram and hard disk is put and is also produced appreciable heat simultaneously, for making the computer can normal operation in the operating temperature range of allowing, then must be by means of extra heat abstractor, to lower the harmful effect of heat for the computer module running.
And fan is a kind of easy and heat abstractor of being widely used most, rotating the air make arround the heat generating component by flabellum produces fast and flows, with effect heat that heat generating component produced rapidly by band from, to reach its thermolysis, yet its radiating effect but is not enough to satisfy its heat conduction efficiency because of area of dissipation, make its heat dissipation drop occur compared to expection, though utilize a plurality of heat radiating fin structures to be attached at heat generating component afterwards, increase its area of dissipation with this, quicken its heat conduction efficiency, see through again fan blow with thermal source force band from, but because of the throughput of its fan still belongs to limited, its radiating effect still can't effectively be improved, therefore, the radiator fan of the many groups of prior art utilization series connection, attempt increasing the throughput of its fan, but be difficult to carry out because of the restriction that is subject to the space, strengthen its throughput and increase motor rotary speed, then can improve the motor manufacture difficulty, and the increase of motor rotary speed also has the upper limit, even be easy to generate a large amount of noises, vibrations and heat, the limit that causes it to be difficult to carry out.
As previously mentioned, the lifting of the usefulness of fan own has its restriction that is difficult to break through, make its radiating effect be difficult to promote, cooling extent still belongs to limited, but for solving the radiating requirements under the electronic building brick computing high speed, the solution that certainly will will seek other, therefore prior art discloses a kind of water-cooled power converter, be to utilize a water-cooled head to be adsorbed on the heat generating component, as CPU or disc driver, be cooling fluid extract out to be imported in its water-cooled head from water tank by a motor, described cooling fluid and water-cooled head from the adsorbed heat of heat generating component via heat exchange action after, its cooling fluid flows out to a radiating module by the water-cooled head again, via sending water tank again back to after the cooling, help heat radiation by liquid circulation, reduce its heat generating component temperature, its unit is operated smoothly.
Though produce heat exchange through coolant flow and thermal source by the water-cooled head, can reach the effect that is better than utilizing the air-flow heat radiation, but in above-mentioned water-cooling head structure, the heat-absorbent surface of its water-cooled head only concentrates on same place, after causing cooling fluid to import the water-cooled head, the cooling fluid of its inflow only some and heat-absorbent surface produces heat exchange action, and it is too short that cooling fluid rests on time of water-cooled head, cause cooling fluid not absorb enough thermals source as yet, promptly derive by another pipeline, make the thermolysis of water-cooled function limited, therefore, prior art discloses a kind of water-cooled radiating structure in addition, as shown in Figure 1, a described water-cooled body 101 inboards set firmly a plurality of fin 102, form a plurality of unidirectional runners 103, increase its area of dissipation by a plurality of fin 102, after making cooling fluid import a described water-cooled body 101, when seeing through cooling fluid, make cooling fluid and fin 102 generation heat exchanges, to improve its thermolysis by described a plurality of unidirectional runner 103.
In above-mentioned radiator structure, though utilize fin 102 that area of dissipation is increased, described fin 102 formed a plurality of runners 103, bootable cooling fluid is in the flow direction of water-cooled head, its cooling fluid and a plurality of fin 102 contacts area are significantly increased and produce heat exchange, yet the space of its unidirectional runner 103 is still fine and closely woven inadequately, cause cooling fluid fast by described unidirectional runner 103, its residence time still can't significantly promote, make cooling fluid absorb enough thermals source and effectively to promote its thermolysis, desirable part is to the greatest extent still arranged not from fin 102.
