Embodiment
Below in conjunction with accompanying drawing, 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, comprise install hot cabinet 2 additional, install refrigerator 3 additional, the composition such as hot-pipe system 4, extraction fan 5 and closing pipe line 6.Install the rear portion that hot cabinet 2 connects rack 1 additional, install refrigerator 3 additional and connect the rear portion installing hot cabinet 2 additional, extraction fan 5 is arranged in the junction installing refrigerator 3 and closing pipe line 6 additional, and closing pipe line 6 will install refrigerator 3 additional and couple together with air conditioner in machine room 7.Hot-pipe system 4 comprises heat pipe 4-1 and fin two parts, and fin is divided into front-seat fin 4-2 and rear row's fin 4-3.The first half section of heat pipe 4-1 and front-seat fin 4-2 form the evaporation section of hot-pipe system 4, are arranged in and install hot cabinet 2 additional, and the second half section of heat pipe 4-1 and rear row's fin 4-3 form the cooling section of hot-pipe system 4, are arranged in and install refrigerator 3 additional.Heat pipe 4-1 adopts high performance aluminium ammonia axial-grooved heat pipe, arranges, make the vertical height of hot-pipe system 4 cooling section higher than evaporation section with certain angle of inclination, ensures 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 can take integrally formed or extruding or cold expanding or screw fastening mode to realize with the preparation of front-seat fin 4-2, rear row's fin 4-3 with being connected.In order to ensure the patency of air current flow in whole system, the arranged direction of fin needs consistent with air current flow direction.Therefore, front-seat fin 4-2 is transverse arrangement of turbo, consistent with thermal current 13 direction that rack 1 is discharged, and rear row's fin 4-3 is vertical layout, consistent with installing refrigerator entrance cold airflow 11 direction additional.Have a lot of strip square groove installing hot cabinet 2 additional and install additional between refrigerator 3, for strip heat pipe 4-1 through and airflow, and the bottom installing refrigerator 3 additional has air vent hole for floor cold airflow and enters, and top has air vent hole and flows out for heat of mixing air-flow.Install hot cabinet 2 additional, install refrigerator 3 additional and closing pipe line 6 forms a cold and hot channel enclosed system, they and air conditioner in machine room 7, floor air supply system form a complete air-flow closed circulation.
The course of work of a kind of data center's energy-saving cooling system based on hot pipe technique of the present invention is as follows:
1) front portion that the cold air after air conditioner in machine room 7 refrigeration delivers to rack 1 through floor air supply system forms rack entrance cold airflow 9.The amount of heat that in rack 1, server 8 produces is taken away through cold airflow 9, discharges from rack rear portion, when not adopting energy-saving cooling system of the present invention, can form the hot gas group 10 of much high temperature.Rack rear portion is close to by these hot gas group 10, forms a high temperate zone, and there is thermal stratification phenomenon, have a strong impact on the service behaviour of server 8.
2) the object of the invention is these hot gas group 10 to take away fast, and make it away from the outlet of rack 1, thus reduce the working temperature of server 8.The front-seat fin 4-2 and the hot gas that install hot-pipe system 4 in hot cabinet 2 additional roll into a ball 10 bump contact, and front-seat fin 4-2 heats up, and hot gas rolls into a ball 10 then significant hypothermals, thus the first half section of heat pipe 4-1 heats up, and heat pipe 4-1 realizes automatic startup optimization.Because the heat-transfer capability of heat pipe is very strong, heat transmits to the second half section of heat pipe 4-1 fast from the first half section of heat pipe 4-1.
3) cold airflow 11 sent into by floor air supply system in refrigerator 3 bottom air vent and the rear row's fin 4-3 bump contact installing hot-pipe system 4 in refrigerator 3 additional is installed additional, heat from second half section of heat pipe 4-1 through after arrange fin 4-3 and be delivered to cold airflow 11, thus the cooling of the second half section of heat pipe 4-1, cold airflow 11 heats up after flowing through rear row's fin 4-3.
4), after hot gas group 10 transfers heat to hot-pipe system 4, can flow into install additional in refrigerator 3 through installing heat pipe 2 additional and installing strip square groove between refrigerator 3 additional along the direction of front-seat fin 4-2, and be mixed to form heat of mixing air-flow 14 with the cold airflow 11 after heating up.Heat of mixing air-flow 14 is taken away by extraction fan 5 and is entered in closing pipe line 6, forms thermal current return air 12, sends cooling processing in air conditioner in machine room 7 back to.
Above the preferred embodiment of the present invention is illustrated, but the present invention is not limited to above-described embodiment.To one skilled in the art, in the category described in claims, various modification or fixed case can be expected apparently, certainly also belong to technology category of the present invention.
