Description
[technical field]
The utility model is about a kind of heat abstractor, particularly about a kind of heat abstractor that adopts heat pipe.
[background technology]
Along with developing rapidly of electronic industry, arithmetic speed as central processing unit electronic building bricks such as (CPU) increases substantially, and the heat of its generation also increases severely thereupon, and how the heat with electronic building brick distributes, to guarantee its normal operation, be the problem of industry research always.
Traditional radiating mode is the radiator that a metal material is set above the heating electronic building brick, this radiator has pedestal, the pedestal lower surface contacts with electronic building brick, its upper surface then is provided with some fins, pedestal absorbs the heat that electronic building brick produces, and by fin heat is distributed in the surrounding air, for strengthening the rate of heat exchange of fin and surrounding air, usually further add and put a fan, to strengthen gaseous exchange in the fin top.Though above-mentioned heat abstractor can distribute the part heat that electronic building brick produces, by the radiator conduction heat of metal material, the coefficient of heat conduction of metal is limited, causes the amount of thermal conduction of radiator under unit interval, unit volume limited merely for it.Traditional simple metal radiator heat-dissipation mode can not satisfy the radiating requirements of golf calorific value electronic building brick.
At present, industry is increasing by the heat abstractor of heat pipe conduction heat, heat pipe is to be evacuated to vacuum state seal pack into capillary structure thing (as metal powder sintered thing, groove structure, screen net structure etc.) and hydraulic fluid (as water, alcohol etc.) in the metal body after, and the process of carrying out liquid gas two phase change after being heated by hydraulic fluid absorbs and release heat.No. the 547914th, the TaiWan, China patent announcement of announcing on August 11st, 2003, promptly disclose a kind of electronic building brick heat abstractor that uses heat pipe, its heat pipe roughly is " U " shape, heat pipe one end is plugged in the radiator base, its other end then is plugged in the perforation of some fins, adds to put a fan above fin.Along with electronic installations such as computer develop towards miniaturization, its volume is more and more narrow and small, to the useful space that can hold electronic device is reduced thereupon, the heat abstractor that above-mentioned TaiWan, China patent announcement is disclosed for No. 547914, near the computer cabinet top cover time, the pitch-limited between fan and top cover causes the back pressure of fan to increase, make extraneous cold air enter the limited speed of heat abstractor, thereby influence radiating effect.
[summary of the invention]
The purpose of this utility model is to provide a kind of heat-pipe radiating apparatus that still can guarantee better heat dissipation effect in narrow and small accommodation space.
The utility model heat-pipe radiating apparatus comprises second radiator, a fan and at least one heat pipe, and each radiator has a pedestal and some fins that is arranged on the pedestal, and said base has at least one inclined-plane; Said fans is interposed between second radiator; Above-mentioned at least one heat pipe two ends are plugged on the second radiator respectively.
Because heat pipe of the present utility model connects second radiator, can make heat conduct on the second radiator rapidly, and fan is interposed between second radiator, when being installed in the accommodation spaces such as computer cabinet when heat-pipe radiating apparatus, even the spacing of the top cover of itself and computer cabinet is less, cold air also can carry out heat exchange with second radiator by wherein radiator importing, avoids the back pressure of fan to increase; In addition, because the pedestal of second radiator all has the inclined-plane, its inclined-plane can guide to pedestal with airflow smooth, thereby improves radiating efficiency.
[description of drawings]
Fig. 1 is the solid combination schematic diagram of the utility model heat-pipe radiating apparatus.
Fig. 2 is the perspective exploded view of the utility model heat-pipe radiating apparatus.
[embodiment]
See also Fig. 1, the utility model heat-pipe radiating apparatus comprises one first radiator 10, one second radiator 30, a fan 50 and two heat pipes 70.First radiator 10 contacts with heat-generating electronic elements (figure does not indicate), and second radiator 30 is positioned at first radiator, 10 tops, connects by above-mentioned two heat pipes 70, and said fans 50 is folded between first, second radiator 10,30.
Please continue to consult Fig. 2, first radiator 10 has one first pedestal 12 and is set in some first fins 14 on first pedestal 12.Above-mentioned first pedestal 12 roughly is the halfpace shape, has a horizontal surface 122 and two inclined-planes 124, and this lower surface 122 fits with electronical elements surface, offers two through hole 126 at the axis direction of first pedestal, 12 upper edge halfpaces, and heating tube 70 plugs.Above-mentioned first fin 14 is arranged in parallel and is located on two inclined-planes 124, two inclined-planes 124 of corresponding first pedestal 12 in the bottom of each first fin 14 are provided with a trapeze cut 142, the place, two edges of above-mentioned breach 142 inclined surface 124 bends out flanging 144 respectively, to increase the contact area of first fin 14 and first pedestal 12.
The structural similarity of the structure of second radiator 30 and first radiator 10, it also has one and roughly is second pedestal 32 of halfpace shape and is positioned at some second fins 34 that are arranged in parallel on second pedestal 32.Offer a groove 328 along the axis direction of halfpace respectively on two inclined-planes 324 of second pedestal 32, above-mentioned second fin, 34 respective grooves 328 places also offer a groove 346, thereby form a through hole, with ccontaining heat pipe 70.Each second fin, 34 both sides forms a flanging 342 that tilts to central authorities respectively near the corner of fan 50, and the inclined-plane that above-mentioned flanging 342 common formation two are tilted to central authorities enters with direct cold air.
