Description

The computer chip heat abstractor

Technical field

The utility model relates to the chip cooling technology, more particularly, relates to a kind of computer chip heat abstractor.

Background technology

Along with the update of computer, had only double-core, four nuclears that server could usefulness to get into the ordinary family user now originally, and in the modern enterprise server, industrial computer CPU quantity from 1 nuclear; 2 nuclears; 3 nuclears, 8 nuclears till now, travelling speed is more and more faster, and the temperature of CPU is also increasingly high; This must rely on heat that the forced heat radiation technology produces CPU in time, dissipate fast; According to law of physics (Newton's formula, Fourier law, the second law of thermodynamics) heating starting point is core cpu, and terminal point is at atmospheric envelope, and good heating radiator (system) should have " three essential characteristics ":

A. heat is from starting point, core cpu, the atmospheric envelope of breasting the tape, and the transmission distance should be fast as far as possible, short;

B. heat is transferred to the end point process from starting point, and thermal resistance should be as far as possible little;

C. heat is transferred to terminal point from starting point and distributes the process, and the two ends temperature difference should be big as far as possible;

At present, existing ripe radiating mode can be divided into air-cooled, heat pipe; Liquid cooling, semiconductor refrigerating, compressor cooling etc.; Fan engages the air cooling way of radiating fin heat radiation because comprehensive first, second physical principle advantage; Add its good economy performance, simple in structure by extensive employing, its principle is that fan blade rotation produces the air strong convection, and the heat of taking away between the radiating fin by force to be absorbed also directly is distributed in the atmosphere.

And at present; The computing machine of standard configuration (comprising server, industrial computer) inside so long as critical elements (electronic chip high) like integrated levels such as CPU, video cards thermal value is the highest also the most concentrated at work; Must force to install heat abstractor; When heat abstractor goes wrong, gently then slack-off, the deadlock of computer run, weight person causes the temperature rising to burn element, full machine collapse deadlock (the normal temperature upper limit 50 is spent)

Since radiator fan is to rely on airflow to cross the radiating fin surface to take away heat and belong to the active heat removal technology; Just present prior art; One same defect is all arranged, and as shown in Figure 1, promptly radiator fan 1 must be built in computer-internal; And be fixed on the radiating fin 3 of chip 2; And according to the 3rd of law of physics (Newton's formula, Fourier law, the second law of thermodynamics): heat is transferred to terminal point from starting point and distributes the process, and the two ends temperature difference should be big as far as possible, that is to say that heat must discharge as early as possible, distribute into atmosphere.

But existing radiator fan technology can't change owing to computer motherboard designs C PU position; The CPU radiator fan also and then is placed in cabinet inside; Cause radiator fan directly heat to be distributed earlier at cabinet inside and produce used heat, rather than directly discharge the cabinet exosphere, radiator fan unavoidably receives the restriction in life-span working time as the rotation consumable accessory simultaneously; In running without interruption for a long time, exist a large amount of dusts of suction and fan insufficient lubrication and produce noise, the fault stall of fan own; Difficult in maintenance three big shortcomings are decomposed in dismounting, and this also is that we computer equipment maintenance personnel pay close attention to and one of emphasis problem that often solves, when the problem of generation; Need the professional to the fault machine; Take to shut down, decompose cabinet, check, disassemble, change or clear up problematic fan, work loaded down with trivial details do not say consuming time also long, when radiator fan in computing machine on visual plant and key sector production is also had very big influence when breaking down.

The utility model content

To the above-mentioned shortcoming that exists in the prior art, the purpose of the utility model provides a kind of computer chip heat abstractor, can thoroughly solve the not good and fan of cooling effect and be prone to impaired problem.

For realizing above-mentioned purpose, the utility model adopts following technical scheme:

This computer chip heat abstractor comprises radiating fin and the fan of being located at chip top, and described fan is installed on the case of computer through fan board, and is connected through the flexible duct pipe between radiating fin and the fan.

Described flexible duct pipe comprises interior wind channel tube that is used for air intake and the outer wind channel tube that is used for air-out, and outer wind channel tube is sheathed on outside the interior wind channel tube.

Described fan board lower end is respectively equipped with the interface of inside and outside wind channel tube, is the fan installation place in the middle of the upper end, is provided with the air outlet that communicates with outer wind channel tube all around.

Also be provided with the wind channel tube fixed mount on the described radiating fin, wind channel tube fixed mount lower end and radiating fin are fixed, and the upper end is respectively equipped with the interface of inside and outside wind channel tube.

In technique scheme; The computer chip heat abstractor of the utility model comprises radiating fin and the fan of being located at the chip top; Described fan is installed on the case of computer through fan board, and is connected through the flexible duct pipe between radiating fin and the fan.Fan can be concentrated cold wind is blown on the radiating fin and with its heat energy through the flexible duct pipe and directly discharge housing, plays good cooling effect, simultaneously; Because fan is installed on the shell; Not only improved the fan work environment, and easy disassembly, help the quick maintenance of fan.
