Description

The no-noise liquid cooling computer cabinet

Technical field

The utility model relates to a kind of computer cabinet, particularly a kind of no-noise liquid cooling computer cabinet.

Background technology

The radiating mode of the electronic component in the active computer cabinet mainly contains: 1, unpowered self-loopa air cooling: promptly finned enlarges area of dissipation on needs radiating electronic chip, by heat radiation and air self-loopa heat is dispersed in the air, reaches the purpose of chip cooling.Its shortcoming is that heat-sinking capability is low, can't satisfy the heat radiation requirement of modern high power electronic system such as computing machine.2, fan helps circulation air cooling: also installed fan after the finned on the electronic chip additional on heat radiator, increase air velocity by fan, to reach the purpose of taking away heat fast from heating radiator.Its shortcoming is that fan brings noise, and rate of air circulation is big, makes easily to pile up dust in the cabinet, also pollutes indoor environment.In addition, use for a long time with fan, aging aft-fan noise can be bigger.3, common liquid cooling: by the liquid cooling head that is installed on the high euthermic chip, pump, conduit and heat exchanger are formed, and pump makes liquid circulate in conduit, in liquid cooling head and the heat exchanger, heat is walked from the liquid cooling headband, and be dispersed in the air by heat exchanger.Its shortcoming also need on the heat exchanger to be to accelerate radiating rate by fan, and noise is unavoidable, in addition, this system can only carry out the emphasis heat radiation to high euthermic chip, can't dispel the heat to whole electronic system, long-term use causes cabinet inner product heat, damage system easily comprehensively.4, heat pipe radiating system: by heat pipe, fast the heat on the high euthermic chip is taken on the box body, box body is made by large-area heat sink material, by large tracts of land cabinet surface heat is distributed to air.Its shortcoming is that cost is too high, system complex, and also can only dispel the heat to local electronic chip, long-term use causes cabinet inner product heat, damage system easily.

The utility model content

The purpose of this utility model is to provide a kind of simple in structure for the deficiency that solves above-mentioned technology, and noise-less pollution can not brought dust and dirt in the cabinet, and can be to the no-noise liquid cooling computer cabinet of the comprehensive heat radiation of electronic unit in the cabinet.

In order to achieve the above object, a kind of no-noise liquid cooling computer cabinet that the utility model is designed, it comprises the cooling cabinet shell that high-heating radiation coefficient Heat Conduction Material is made, it is characterized in that the computing machine electronic unit sets within it is equipped with in the chassis shell of insulativity heat-conducting liquid, and the computing machine electronic unit is immersed in the insulativity heat-conducting liquid.The cooling cabinet shell that described high-heating radiation coefficient Heat Conduction Material is made is copper and aldary or aluminium and aluminium alloy chassis shell.

During use, with the computing machine electronic unit, as computer motherboard, CPU, power supply or the like immerses in the insulativity conductive fluid, because high insulation characterisitic, electronic system energy operate as normal can not cause electronic failures such as short circuit after immersing the insulativity conductive fluid.The insulativity heat-conducting liquid places in the chassis shell, and during the system operate as normal, the heat that computing machine electronic unit such as CPU etc. send conducts to chassis shell by the insulativity heat-conducting liquid and is dispersed in the outside air by chassis shell.

A kind of no-noise liquid cooling computer cabinet provided by the utility model, the heat that utilizes the high-insulativity heat-conducting liquid that the work of computing machine electronic unit is produced takes the chassis shell surface to and dispels the heat, heat-conducting liquid can be fast exported to the heat of computing machine electronic unit generation outside the cabinet, replace the air-cooled liquid cooling system that uses in single case shell of tradition and the computer to dissipate heat etc. with this computer cabinet, make cabinet noise-less pollution when work, cleaning in the cabinet, can not bring dust and dirt into, and it is with low cost, and can dispel the heat to the computing machine electronic unit comprehensively, heat-sinking capability is strong, has reduced the failure rate of system.

Embodiment

The utility model will be further described in conjunction with the accompanying drawings below by embodiment.

Embodiment 1

As shown in Figure 1, a kind of no-noise liquid cooling computer cabinet that present embodiment is described, it comprises the cooling cabinet shell 1 that high-heating radiation coefficient Heat Conduction Material is made, computing machine electronic unit 3 sets within it in the chassis shell 1 that is equipped with insulativity heat-conducting liquid 2, and computing machine electronic unit 3 is immersed in the insulativity heat-conducting liquid 2.The cooling cabinet shell 1 that described high-heating radiation coefficient Heat Conduction Material is made can adopt copper, aldary or aluminium and aluminum alloy materials.

The computing machine electronic unit 3 that is immersed in the insulativity heat-conducting liquid 2 that present embodiment is described is computer motherboard, CPU, power supply, hard disk etc., and can be on CPU finned 4, the heat that makes CPU produce can conduct faster to insulativity heat-conducting liquid 2, during the computing machine operate as normal, the heat that produces makes the insulativity heat-conducting liquid form self-loopa, each point temperature in the homogenizing cabinet, and heat conducted to large-area cooling cabinet shell 1, and be dispersed in the external environment by it and go, reach the purpose of computer system heat radiation.When insulating heat-conductive liquid convection current in the cabinet is strong inadequately, can install motor or pump 5 additional and increase the interior liquid convection of cabinet, faster heat transferred is arrived cooling cabinet shell 1,, can not hear any noise outside the chassis shell 1 because motor or pump 5 integral body are immersed in the insulating heat-conductive liquid 2.

Because the electrical conductivity of most of board substrates is 4.5, so the insulativity heat-conducting liquid 2 that present embodiment provided is that electrical conductivity is less than the liquid below 4.5.As most liquid state organics, electrical conductivity at 3.5 to 4.0 vegetable oil, electrical conductivity at industrial insulating oil of 2.5 to 3.0 or the like.

Because insulativity heat-conducting liquid and high-heating radiation coefficient Heat Conduction Material can both be found in corresponding material handbook, no longer specifically exemplify one by one at this.
