Description

Heat abstractor

Technical field

The utility model is a kind of heat abstractor, is applied to a main frame, and the electronic building brick in this main frame is dispelled the heat, and this electronic building brick can be central processing unit.

Background technology

Computer is made up of many electronic building bricks, it includes assemblies such as motherboard, power supply unit, Winchester disk drive, floppy drive and CD-ROM drive, to carry out the default function of some computers by these electronic building bricks, for example: the broadcast of the editor of file, the computing of program, film etc.

Electronic building brick in these computers can produce heat energy unavoidablely in running, and these heat energy must be distributed to surrounding environment with heat energy by other approach such as heat conduction, thermal convection or thermal radiation, are unlikely to make the electronic building brick temperature too high and influence the stability and the reliability of product.And in computer system, wherein important with the heat dissipation problem of the assembly-central processing unit (CPU) of main execution computing again, so the heat dissipation problem of the central processing unit problem of making great efforts to overcome for computer vendors institute desire.

Along with the processor development of technology, central processing unit (Central Processing Unit, CPU) operating frequency has been increased to more than the 3--4GHz, and its heating power more reaches more than the 115W, if the heat energy that central processing unit produced can not fully be got rid of, certainly will influence the function of computer, shorten its useful life, therefore, heat dissipation problem is on the rise along with the raising of Computing frequency.

Tradition is with solving the technological means that central processing unit dispels the heat, mainly be to utilize radiator and radiator fan to arrange in pairs or groups, radiator is wherein made by metal material, radiator includes a base, the radiating fin that has a plurality of tile verticallies on the base, base directly is arranged on the central processing unit and is in contact with it, when heat energy that the central processing unit execution work is produced can be passed to via base on the heat radiation eel sheet, radiator fan is arranged on the radiating fin, the air-flow that utilizes radiator fan to produce is blown in the radiating fin, utilize the air-flow that radiator fan produces and the radiating fin of high temperature to carry out heat exchange, and the heat on the radiator is taken away, and then the temperature of reduction central processing unit reaches the purpose of heat radiation.

Raising along with the central processing unit operating frequency, the clock of radiator fan also and then increases, and also release 4500 commentaries on classics, 5400 commentaries on classics, 7200 commentaries on classics even the above fan of 10000 commentaries on classics on the market successively, with the temperature in the reduction main frame, and then the useful life of prolongation electronic building brick.

Though these high-revolving fans have been suppressed the heat of central processing unit, compacting is its noise that makes us bothering incessantly, so when central processing unit moved at high frequency, except heat dissipation problem originally, noise problem also becomes needed the problem that overcomes badly.

Because the radiating effect of liquid is than the excellent in heat dissipation effect of gas, therefore, the various water-cooled cooling systems of the numerous and confused release of manufacturers at present, with radiator and the radiator fan of water-cooled cooling system in conjunction with script, heat energy is taken away in circulation by liquid (normally utilizing distilled water), to improve its radiating effect.

Please refer to shown in Figure 1, be the system architecture diagram of water-cooled cooling system in the traditional calculations machine host, consist predominantly of a central processing unit (not shown) in this main frame, be arranged at a refrigerating sheet (cold plate) 10, one power supply unit 20, a radiator 30 and a water-cooled module 40 on the central processing unit.

This central processing unit is to be arranged on the motherboard 50, as user during at executive utility or function choosing-item, promptly is to carry out signal by central processing unit to handle and data computation.

Include a pump (not shown), a water leg (not shown) and a soft water pipe 41 in order to storaging liquid in this water-cooled module 40.Full of liquid in the soft water pipe 41, and can be connected to refrigerating sheet 10 on the central processing unit, the driving by pump circulates liquid in soft water pipe 41, to take away the heat energy that central processing unit is produced.

Another rigid water pipe 42 connects the radiator 30 of water-cooled modules 40 and power supply unit 20 rear ends, cools off this radiator 30 and is arranged at water pipe 41 in the radiator 30 with the air-flow that fan was blown out by power supply unit 20, and reach the effect of heat radiation.

The air-flow that only uses single fan (being the fan of power supply unit 20) running the time to be produced in this water-cooled cooling system brushes radiator 30 and is arranged at rigid water pipe 42 in the radiator 30, to take away the heat energy of liquid in the rigid water pipe 42.Therefore, when design, often need be by increasing the thickness w of entire radiator 30, to reach required radiating effect.

Yet, when the thickness w of radiator 30 increases, incident is the increase of whole main frame volume, promptly increase the required space that occupies of whole main frame, for the compact trend development, the increase of radiator 30 thickness w will be a big shortcoming for present main frame.In addition, other assembly also can't be furnished in the space of radiator 30 belows, will cause its waste of side space down.

Except above-mentioned shortcoming, the traditional heat-dissipating system numerous costs that cause of its composition assembly are higher; Consider with the assembling bedding angle in addition, because the interference when power supply unit 20 can cause assembling, therefore, power supply unit 20 in the need elder generation dismounting main frame and other can cause the assembly of interference, again modular refrigerating sheet 10, radiator 30, water-cooled module 40, soft water pipe 41 and rigid water pipe 42 are packed in the lump in the main frame, at last, the more previous assembly of removing is reinstalled in the main frame, just finish the process of whole erection.And this assembling process seems loaded down with trivial details unusually, increases the difficulty on the assembled configuration on foot.Moreover, if carry out in the future that main frame intraware upgrading is replaced or during maintenance activity, also will produce unnecessary puzzlement.
