Description
Technical field the present invention relates to a kind of cooling system manufacturing technology of integrated circuit heat-pipe radiating apparatus, and exactly, it is a kind of cooling and radiation device of electric installation.
Background technology is along with the develop rapidly of semiconductor technology, and the integrated level of integrated circuit (IC) chip improves constantly, and the operating frequency of chip also improves constantly, and the caloric value of integrated circuit (IC) chip has increased widely.Especially in computer realm, the heat dissipation problem of high primary frequency CPU also more and more becomes a problem that can not be ignored.
The heat dissipating method that the most generally uses is that the heat that CPU produces is directly delivered to fin at present, and the heat of fin being accumulated by the fan of quick rotation is taken away again.Although the capacity of heat transmission of aluminum or copper fin is very strong, and can increase area of dissipation by increasing fin.But owing to the increase of fin efficiency along with the distance of fin and thermal source (CPU) reduces, thus its fin thermal resistance have a limit.Therefore the thermal resistance of heat pipe (phase transformation) heat transfer element adopts heat pipe (phase transformation) heat transfer element can improve fin efficiency greatly than the low tens of and even hundreds of times of thermal resistance of aluminum or copper heat transfer element, thereby breaks through the fin thermal resistance limit.
As everyone knows, the radiator of hot pipe technique, the radiator of the employing hot pipe technique of COOLMASER have for example appearred adopting in the domestic market.And Chinese patent CN2458659Y discloses a kind of desktop computer CPU phase-change heat sink, and these all are goodish schemes.But because the structural manufacturing process complexity, the price height can't substitute existing product.
The summary of the invention the purpose of this utility model is that a kind of structural manufacturing process of design is simple, the integrated circuit heat pipe radiating system that cost is low.
Summary of the invention the utility model is achieved in that a kind of integrated circuit heat-pipe radiating apparatus that comprises radiator fan, heat transfer fin, base plate, the plate outer surface of radiator and integrated circuit upper surface fit tightly, heat pipe heat radiation body upper surface is provided with the fin of projection, the fin upper end closed, hollow, the lower end communicates with the casing that base plate constitutes sealing with the heat pipe heat radiation body, and heat pipe heat radiation body and base plate constitute the negative pressure of vacuum structure, and fin is fixed on the outer wall of fin.
The utility model is applicable to the heat pipe phase-change radiation system of integrated circuit, and it is simple in structure, and cost is low.Of the present utility modelly be to have adopted the heat pipe heat radiation element, the thermal resistance from the thermal source to the heat-delivery surface reduced significantly, thereby improve fin efficiency, increased the efficiently radiates heat area of radiator.And simple in structure, if adopt advanced technologies such as compression casting or vacuum pressing and casting, heat pipe heat radiation body and fin can one-shot formings, and cost reduces significantly.
Description of drawings is further described the utility model below in conjunction with accompanying drawing:
Fig. 1 is a front view of the present utility model
Fig. 2 is the cutaway view of A-A of the present utility model
Fig. 3 is a left view of the present utility model
1 is fin; 2 is column; 3 is radiator fan; 4 is the heat pipe heat radiation body; 5 is fin; 6 is working media; 7 is base plate.
The embodiment the purpose of this utility model is also again further to realize by following technology solution: above-mentioned a kind of integrated circuit heat pipe (phase transformation) cooling system, base plate 7 outer surfaces and the integrated circuit upper surface of wherein said radiator fit tightly, and are coated with silica gel etc. to reduce contact heat resistance.
Heat pipe heat radiation body 4 upper surfaces are provided with the fin 1 of some projectioies, fin 1 upper end closed, hollow, the lower end communicates with the casing that base plate 7 constitutes sealing with heat pipe heat radiation body 4, fin 1 inner surface is processed groove-shaped wick, can be dovetail groove, rectangular channel or vee gutter, conduct heat with reinforced transformation.And the fin 5 of augmentation of heat transfer is all arranged outside the fin 1 of every projection, to increase area of dissipation.
The working media 6 that wherein said heat pipe heat radiation body 4 and base plate 7 constitute the negative pressure of vacuum structures is any in the organic substance compatible with selected case material.The working media 6 that heat pipe heat radiation body 4 and base plate 7 constitute the negative pressure of vacuum structures can be any in the organic substance compatible with selected case material.For example: at 0-100 ℃, the working media 6 compatible with aluminium has ammonia, fluorine Lyons-21, Freon-11, freon-113, acetone; The working media compatible with copper has Freon-11, freon-113, hexane, acetone, ethanol, methyl alcohol etc.
Heat pipe heat radiation body 4 is aluminium and aluminium alloy or copper and copper alloy with the material of base plate 7 and fin 5 usefulness.Above-mentioned a kind of integrated circuit heat pipe (phase transformation) cooling system, upper surface that can described therein base plate 7 is provided with some surface texture for strengthening boiling, and the upper surface of base plate 7 is surface textures such as the thin ball of sintering, filamentary webs, burr body, pearl particle.
A kind of integrated circuit heat pipe (phase transformation) cooling system, it includes radiator fan 3, heat pipe heat radiation body 4, heat transfer fin 5, base plate 7, the column 2 and the working media 6 of fan is installed.Heat pipe heat radiation body 4 constitutes the casing that seals with base plate 7, and a little amount of work medium 6 is arranged at the bottom in the casing.Heat pipe heat radiation body 4 is provided with the fin 1 of some projectioies to upper surface, fin 1 upper end closed, and hollow, the lower end communicates with the casing that heat pipe heat radiation body and base plate constitute sealing.Fin 1 is outside equipped with the fin 6 of augmentation of heat transfer, and radiator fan 3 is installed in above the heat pipe heat radiation body 4, is fixed on the column 2.
As Fig. 1, the utility model by radiator fan 3, heat pipe heat radiation body 4, fin 5, base plate 7, column 2 and the working media 6 that is enclosed in the negative pressure of vacuum structure that heat pipe heat radiation body 4 and base plate 7 constitute form.The fluid passage of the hollow in the fin of heat pipe heat radiation body 4 projectioies communicates with the cavity that base plate 7 constitutes with heat pipe heat radiation body 4, and fin 5 can be welded on the fin 1, if process conditions permission heat pipe heat radiation body 4 and fin 5 can one-shot formings.Radiator fan 3 is fixed on the column 2.
Its course of work is as follows: base plate 7 outer surfaces and the integrated circuit upper surface of radiator fit tightly.The heat that integrated circuit produces arrives working media 6 through base plate 7.Because the negative pressure of vacuum structure that heat pipe heat radiation body 4 and base plate 7 constitute, working media 6 is under the vacuum negative pressure condition, vaporizes, and produces in the cavity of fin hollow that steam enters 4 some projectioies of heat pipe heat radiation body.Because heat pipe heat radiation body 4 and fin 5 are subjected to the cold wind cooling that radiator fan 3 blows out, so steam condensation here that working media 6 vaporizations produce, then reflux and fall back at last along the fin wall and continue to be heated vaporization in the working media 6, the cooling of realization to integrated circuit so moves in circles.
