Detailed Description
The embodiment of the invention discloses a data center cabinet heat dissipation system, which is used for effectively solving the problem of poor heat dissipation effect of the existing data center cabinet.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a heat dissipation system of a data center cabinet according to an embodiment of the present invention.
In an embodiment, the present embodiment provides a data center cabinet heat dissipation system for dissipating heat of a plurality of data center cabinets 8 in a data center cabinet respectively. Specifically, the data center cabinet heat dissipation system comprises a controller 1, a main inlet 2, a refrigerant radiator 4 and a temperature detector.
The refrigerant radiator 4 has a refrigerant flow channel therein, wherein the refrigerant may be liquid, gas, or both liquid and gas. Specifically, the refrigerant may be water, specifically, other cooling liquids, wherein the low-temperature refrigerant enters the refrigerant radiator 4, and after absorbing heat in the heat absorbing portion, the refrigerant that becomes high-temperature flows out from the outlet, and further, the heat of the heat absorbing portion can be taken away.
The plurality of refrigerant radiators 4 are respectively distributed in each radiating area to radiate heat in different radiating areas, wherein the radiating areas can be divided into different forms according to needs, so that the data center cabinets 8 are generally divided correspondingly, that is, one data center cabinet 8 is one radiating area, and of course, a plurality of data center cabinets 8 can be arranged in one radiating area. The division between the heat dissipation areas is preferably performed in an independent degree of each heat dissipation area, that is, the heat transfer speed of the adjacent heat dissipation areas is obviously reduced compared with the heat dissipation speed in the heat dissipation areas.
The temperature detector is configured to detect the temperature of each heat dissipation area, and the temperature detector may include a plurality of detection ends, which are respectively disposed in each heat dissipation area to correspondingly identify the current temperature of each heat dissipation area, wherein each detection end is preferably disposed at a heat generating element of the heat dissipation area, and of course, may also be disposed at a heat absorbing portion of the refrigerant heat sink 4. Of course, the temperature detector may also be arranged at a position to detect the temperature of the respective heat dissipation area from the outside, for example, by infrared or the like.
The inlet of each refrigerant radiator 4 is communicated with the total inlet 2 through a flow regulating valve 9, namely, the flow regulating valves 9 are arranged corresponding to the refrigerant radiators 4, so that the flow of the refrigerant obtained from the total inlet 2 by the refrigerant radiator 4 in unit time can be regulated by regulating the opening degree of the corresponding flow regulating valve 9, the larger the flow is, the better the heat dissipation effect of the refrigerant radiator 4 is, and the smaller the flow is, the worse the heat dissipation effect of the refrigerant radiator 4 is. Note that, among them, the flow rate adjustment valve 9: the valve can be a two-stage regulating valve, such as an on-off valve, so that the flow can be regulated from nothing to nothing by opening and closing; or more than three stages of flow regulating valves 9 or stepless flow regulating valves 9.
And the controller 1 controls the opening degree of the corresponding flow regulating valve 9 according to the temperature value in each heat dissipation area detected by the temperature detector. For example, for the switch valve, when the temperature detector detects that the temperature of a certain heat dissipation area exceeds a first predetermined temperature, the corresponding switch valve is controlled to be opened so as to dissipate heat through the refrigerant heat sink 4, and when the temperature detector detects that the temperature of a certain heat dissipation area is lower than a second predetermined temperature, the corresponding switch valve is controlled to be closed so as to stop dissipating heat through the refrigerant heat sink 4, wherein the second predetermined temperature is not greater than the first predetermined temperature, and preferably is lower than the first predetermined temperature. If the flow regulating valve 9 is a stepless regulating valve, the opening of the corresponding flow regulating valve 9 is controlled to be increased along with the increase of the temperature of the current heat dissipation area detected by the temperature detector, so that the flow of the refrigerant in unit time is increased, and the heat dissipation efficiency is increased.
In this data center rack cooling system, when there are a plurality of data center cabinets 8, divide different heat dissipation areas, each heat dissipation area arranges refrigerant radiator 4 respectively promptly, when the high-speed operation of equipment in certain data center cabinet 8, calorific capacity risees, can correspond the temperature that leads to current heat dissipation area and rise, and when thermodetector detected this heat dissipation area temperature and risees, then control flow control valve 9 increases the degree of opening to increase the refrigerant flow, and then increase radiating efficiency, with the heat dissipation in the regional heat dissipation of accelerating current heat dissipation. In this data center rack cooling system, set up different heat dissipation areas, and each heat dissipation area has arranged refrigerant radiator 4 respectively, has set up flow control valve 9 respectively correspondingly for controller 1 can be according to thermodetector's detection effect, and the coolant radiator 4 that accurate control corresponds increases the radiating efficiency. Thereby improving the utilization efficiency of the refrigerant and more effectively dissipating heat. In conclusion, the data center cabinet heat dissipation system can effectively solve the problem that the existing data center cabinet is poor in heat dissipation effect.
Further, the temperature radiator may include a plurality of detection terminals as described above, but when the heat dissipation area increases and the area range is large, such detection requires a large number of wires and a large number of terminals, which results in an increase in the overall cost. For this reason, it is preferred here that the temperature detector therein is a thermographic analyzer 3. That is, the thermal imaging of the current whole area is detected according to the thermal imaging analyzer 3, and then the thermal imaging is analyzed by the controller 1 or the thermal imaging analyzer 3 to obtain which heat dissipation area the high temperature area is specifically located, and the controller 1 then controls the opening and closing degree of the flow regulating valve 9 corresponding to the high temperature area.
Further, even if the heat generating portion in the heat dissipation area is disposed close to the refrigerant heat sink 4, the heat dissipation effect may still be poor, and in order to accelerate the flow of the internal air and to improve the heat dissipation efficiency, it is preferable to further include a heat dissipation fan 5 for accelerating the air flow speed at the refrigerant heat sink 4, so that when the refrigerant heat sink 4 is closed, the heat dissipation fan 5 can be independently controlled to start heat dissipation, or the heat dissipation fan 5 and the refrigerant heat sink 4 start to work together. Specifically, the controller 1 may control the heat dissipation speed of the corresponding heat dissipation fan 5 according to the temperature value in each heat dissipation area detected by the temperature detector, that is, the rotation speed of the blades of the heat dissipation fan, and at this time, the heat dissipation fan 5 and the refrigerant heat sink 4 in the same heat dissipation area may be controlled in a linkage manner.
For the convenience of control, it is preferable that a total outlet 6 is further included, and the outlet of each refrigerant radiator 4 is communicated with the total outlet 6, wherein the inlet and the outlet of each refrigerant radiator 4 are preferably disposed on the same side, but may be disposed on opposite sides. The coolant radiator 4 is preferably a water-coal radiator, in which water flows as coolant.
In order to better radiate heat of the heat radiation fan 5 and better arrange the structural position relation, it is preferable that the heat radiation fan 5 is arranged on one side of the refrigerant radiator 4 and the air outlet channel 7 is arranged on the other side. Because the refrigerant radiator 4 is disposed close to the heating portion, the heat can be absorbed more directly, and then when the temperature rises, the refrigerant radiator 4 is cooled by air, which can also achieve the effect of radiating the heating portion. Specifically, in order to avoid wind cross-over, it is preferable here that each refrigerant radiator 4 evenly distributes along a straight line, and for better control wind direction, it is the same that each radiator fan 5 wind direction is preferable here to make the opposite side air outlet channel 7 of each refrigerant radiator 4 establish ties in proper order, and it extends to 8 external sides of cabinet of data center cabinet to prefer air outlet channel 7, so that the wind body that heats through refrigerant radiator 4 gathers, and the unified outflow is to the external side of cabinet.
Based on the data center cabinet cooling system provided in the above embodiment, the invention further provides a data center room, where the data center room includes any one of the data center cabinet cooling systems in the above embodiments, and further includes a plurality of data center cabinets, where each refrigerant radiator of the data center cabinet cooling system is respectively arranged at each data center cabinet, and a temperature detector of the data center cabinet cooling system is used to detect the temperature of each data center cabinet. Since the data center room employs the heat dissipation system of the data center cabinet in the above embodiment, please refer to the above embodiment for the beneficial effects of the data center room.
