Description
Technical field
The invention belongs to machine room radiating and hot pipe technique field, are related to a kind of data center's energy-saving cold based on hot pipe technique
But apparatus and system.
Background technology
IDC machine rooms have become the important component part in the national economic development, are propulsion national science and technology industrial informations
With digitized mainstay.With the development of data center's scale and integrated level, information technoloy equipment power density and day in server
All increasings, heat density sharp increase, on the one hand, the electrical power consumed by refrigeration plant quickly increases, the energy consumption problem of machine room is more next
More receive publicity；On the other hand, server radiating problem can become increasingly severe, in some instances it may even be possible to consume mass energy and fortune
Equipment downtime can also be caused because of equipment heating under the cost of battalion's cost.
The investigation of Lawrence Berkeley National Laboratories of the U.S. shows that a typical consumption of data center ratio is：
1) information technoloy equipment (server, switch, router etc.) accounts for 44%；2) refrigeration plant (precise machine room air conditioner, blower fan) accounts for 38%；3)
Power-supply device (UPS, SPM etc.) accounts for 15%；4) illumination accounts for 3%.Therefrom it is not difficult to find out that the power consumption of refrigeration plant is only second to IT master
The power consumption of equipment.
Face energy crisis, currently all data center all in the efficiency that improves empty reconciled data center of employing new technology,
Accurate temperature controlling and air current composition are carried out to refrigeration system.These new technologies include fresh air formula energy conserving system, cold and hot channel enclosed, water

Principle schematic diagram.s of the Fig. 2 for hot-pipe system.
Specific embodiment
Below in conjunction with the accompanying drawings embodiments of the present invention are described further.
As shown in figure 1, a kind of data center's energy-saving cooling system based on hot pipe technique, including install additional hot cabinet 2, install additional cold
Cabinet 3, hot-pipe system 4, extraction fan 5 and closing pipe line 6 etc. are constituted.Install the rear portion that hot cabinet 2 connects rack 1 additional, install refrigerator 3 additional and connect
The rear portion for installing hot cabinet 2 additional is connect, extraction fan 5 is arranged in the junction for installing refrigerator 3 and closing pipe line 6 additional, and closing pipe line 6 will be installed additional
Refrigerator 3 is coupled together with air conditioner in machine room 7.Hot-pipe system 4 includes that heat pipe 4-1 and fin two parts, fin are divided into front-seat fin 4-2
With heel row fin 4-3.The front half section of heat pipe 4-1 and front-seat fin 4-2 constitute the evaporator section of hot-pipe system 4, positioned at installing hot cabinet 2 additional
In, the second half section of heat pipe 4-1 and heel row fin 4-3 constitute the cooling section of hot-pipe system 4, positioned at installing additional in refrigerator 3.Heat pipe 4-1
Using high performance aluminium ammonia axial-grooved heat pipe, arranged with certain angle of inclination, the vertical height for making 4 cooling section of hot-pipe system is higher than
Evaporator section, it is ensured that the backflow of ammonia working medium in heat pipe 4-1.One end of heat pipe 4-1 is connected with the rear wall of rack 1.Heat pipe 4-1 and front row
Fin 4-2, the preparation of heel row fin 4-3 and connection can take integrally formed or extruding or cold expanding or the mode of screw fastening
Realize.In order to ensure the patency of air current flow in whole system, the arranged direction needs of fin are consistent with air current flow direction.
Therefore, front-seat fin 4-2 is lateral arrangement, consistent with 13 direction of thermal current that rack 1 is discharged, and heel row fin 4-3 is vertical cloth
Put, consistent with 11 directions of refrigerator entrance cold airflow are installed additional.Installing hot cabinet 2 additional and installing additional, to be provided with a lot of strips between refrigerator 3 square
Groove, the heat pipe 4-1 for strip are passed through and airflow, and the bottom for installing refrigerator 3 additional is provided with passage and enters for floor cold airflow
Enter, top is provided with passage and flows out for mixing thermal current.Install hot cabinet 2 additional, install refrigerator 3 additional and closing pipe line 6 constitute one cold and hot
Channel enclosed system, they constitute a complete air-flow closed circulation with air conditioner in machine room 7, floor air supply system.
A kind of course of work of data center's energy-saving cooling system based on hot pipe technique of the present invention is as follows：
1) cold air after air conditioner in machine room 7 freezes is cold through the anterior formation rack entrance that floor air supply system is sent to rack 1
Air-flow 9.The amount of heat that server 8 is produced in rack 1 is taken away through cold airflow 9, is discharged from rack rear portion, is not adopting this
In the case of bright energy-saving cooling system, the hot gas group 10 of many high temperature can be formed.Rack rear portion, shape are close to by these hot gas groups 10
Into a height temperate zone, and there is thermal stratification phenomenon, have a strong impact on the service behaviour of server 8.
2) purpose of the present invention is quickly to take away these hot gas groups 10, and makes it away from the outlet of rack 1, so as to drop
The operating temperature of low server 8.Install the front-seat fin 4-2 of hot-pipe system 4 in hot cabinet 2 additional 10 bump contacts are rolled into a ball with hot gas, front
Row fin 4-2 heats up, and the then significant hypothermal of hot gas group 10, so as to the front half section of heat pipe 4-1 heats up, heat pipe 4-1 realizes opening automatically
Dynamic operation.As the heat-transfer capability of heat pipe is very strong, heat is quickly transmitted to the second half section of heat pipe 4-1 from the front half section of heat pipe 4-1.
3) install the cold airflow 11 sent into by floor air supply system in 3 bottom air vent of refrigerator additional and install heat pipe in refrigerator 3 additional
The heel row fin 4-3 bump contacts of system 4, heat are delivered to cold airflow 11 from the second half section of heat pipe 4-1 through heel row fin 4-3
In, so as to the second half section of heat pipe 4-1 lowers the temperature, cold airflow 11 heats up after flowing through heel row fin 4-3.
4) after hot gas group 10 transfers heat to hot-pipe system 4, can be along the direction of front-seat fin 4-2 through installing hot cabinet additional
2 and install strip square groove between refrigerator 3 additional and flow into and install additional in refrigerator 3, and be mixed to form with the cold airflow 11 after intensification and mix
Thermal current 14.Mixing thermal current 14 is evacuated fan 5 and takes away in entrance closing pipe line 6, forms thermal current return air 12, sends machine room back to
Cooling treatment in air-conditioning 7.
Above the preferred embodiment of the present invention is illustrated, but the present invention is not limited to above-described embodiment.Right
For those skilled in the art, in the category described in claims, it should be apparent that it is conceivable that various modifications
Or fixed case, fall within certainly the technology category of the present invention.
