Description

A kind of heat abstractor

The utility model relates to a kind of heat abstractor, is particularly useful for the computer heat abstractor.

General booting computer must produce heat when working, and the computer internal temperature is raise.Well-known computer is inner most important to be with headed by the central processing unit especially, if it is overheated, this central processing unit just can break down so, and cause computer crash, and then cause user's inconvenience, and also can use when serious, this situation occurs on business circles and the industrial community, as stock exchange, production line etc., certainly will cause great loss.

See also shown in Figure 1, structure for general heat abstractor 1 commonly used, the heat energy that central processing unit produced for the machine plate only utilizes devices such as base 11, heat pipe 13 with centralized heat energy, and by fan 15 extraction hot gas, if but in fact the heat energy of the central processing unit inside of machine plate can not active set in, the fan 15 that then is contained in this heat abstractor 1 top just can't be brought into play due effect, performs practically no function; Wherein this base 11 is with after the centralized heat energy, because of between base 11 and the heat pipe 13 being uses colloid 12 bonding, the temperature conductivity extreme difference of colloid 12 wherein, and colloid 12 just can come off under long-term the use, the heat energy of base 11 just can't effectively reach in heat pipe 13, cause central processing unit because of overheated can't operate as normal or damage.

See also shown in Figure 2, the central processing unit of computer is another kind of specification, it is inserted in the slot of machine plate, the central processing unit 9 of another specification wherein, its heat abstractor 14 is heat radiation fin keels 16 of installing one identical size above central processing unit 9, add a fan 15 in heat radiation fin keel 16 tops, wherein heat abstractor 14, there is not collecting system, so can't make radiating efficiency not good unavoidably effectively with centralized heat energy, heat energy is stranded on the heat radiation fin keel 16, and reflux in central processing unit 9, cause temperature to improve once more, because of the overheated central processing unit 9 that causes equally can't operate as normal or damage.

Known to above-mentioned, no matter from manufacturer or user's angle block gauge it, above-mentioned technology is to the greatest extent imperfect, cause meaningless increase in man-hour, and can't reach the effect of expection in the use, and this structure both inconvenience was also impracticable, often for the dealer the dirt disease; Therefore, how above-mentioned shortcoming is forgone the place of the technical difficulties that i.e. this case institute desire solves.

Primary purpose of the present utility model is that a kind of heat abstractor is being provided, when making booting computer, the effective heat energy that central processing unit produced with the machine intralamellar part, base conduction by thermal conductance thermal-arrest seat, and it is concentrated by the heat pipe of thermal conductance thermal-arrest seat, shed by the outside conduction of the radial heat radiator of fin heat-dissipating cylinder again, and the heat energy that another part can't shed voluntarily just concentrates on this in twos in the fan-shaped space between heat radiator, heat energy in this fan-shaped space is concentrated via this wind-collecting cover at last, the forced convertion of carrying out the exhausting formula by this fan is upwards sent again, make the central processing unit of machine intralamellar part can not produce damage, and keep operate as normal because of overheated.

The purpose of this utility model is achieved in that a kind of heat abstractor, comprise thermal conductance thermal-arrest seat, fin heat-dissipating cylinder, wind-collecting cover, fan, wherein base is provided with fixed orifice, heating radiator is fixed in the central processing unit top with screw through fixed orifice, it is characterized in that thermal conductance thermal-arrest seat is made of integrally formed heat pipe and base; Fin heat-dissipating cylinder central authorities are provided with the hollow groove of strip, and the heat pipe of thermal conductance thermal-arrest seat is through in the hollow groove of fin heat-dissipating cylinder; Wind-collecting cover is then established by four mutual vertical junction of baffle plate, and four baffle plate tops are stamped overhead gage and are become a square body, form square storage tank within it, and the storage tank volume is slightly larger than the upper volume of fin heat-dissipating cylinder, and wind-collecting cover is sheathed on fin heat-dissipating cylinder top.

This outer-finned heat-dissipating cylinder is that the axle center is radial and outwards extends a plurality of heat radiator with the hollow groove, and the fin heat-dissipating cylinder is one square, is formed with a fan-shaped gap between heat radiator and heat radiator.

Advantage of the present utility model: radiating effect is good, makes the central processing unit can be because of the bad main frame that damages that dispels the heat, can be effectively with centralized heat energy, and the thermal-arrest seat is one of the forming, and has increased durability, and is easily assembled, can attract the consumer to buy, have industrial utilization.
