The cooling apparatus 1 includes a plurality of cabinets 101, an overhead cooling unit 102, a hot aisle enclosure module 103, at least one fan backplane 104, an overhead cooling unit controller 105, and a switch 106, wherein the plurality of cabinets 101 access the overhead cooling unit controller 105 through the switch 106, respectively, to be adjusted by the overhead cooling unit controller 105.
The plurality of cabinets 101 are divided into two rows of cabinets and arranged oppositely, and a hot channel is defined between the two rows of cabinets, wherein the plurality of cabinets 101 include at least two types of cabinets 101.

The power cord is designed to be installed quickly, and various PDU sockets are supported. The fan back plate is installed rapidly in a modularized mode, and the deployment efficiency of the multiple cabinets is improved.

It will be appreciated by those skilled in the art that the cooling apparatus 1 is not limited to including only 8 cabinets, and is not limited to only two types of cabinets, and may include more types of cabinets, and each type of cabinet may include a greater number. For example, when the cooling device 1 comprises three or more types of cabinets, at least one fan may be arranged behind other types of cabinets, in addition to the first type of cabinet in which the rated wind pressure of the fan wall is the highest.

It should be understood by those skilled in the art that the manner in which the overhead cooling unit controller obtains the linkage information is merely exemplary, and that any manner of obtaining linkage information that may exist or that may later become available, such as may be suitable for use with the present invention, is intended to be included within the scope of the present invention and is hereby incorporated by reference.
Preferably, the overhead cooling unit controller 105 obtaining the linkage information from the switch 106 includes: the switch 106 collects the coordinated information from at least one of the corresponding plurality of cabinets and sends the coordinated information to the overhead cooling unit controller 105 in a predetermined protocol. Specifically, the switch 106 collects linkage information such as an intake air temperature, an outlet air temperature, power consumption, a fan rotation speed, and a wind pressure from at least one of the plurality of cabinets 101, packages the linkage information, and then sends the linkage information to the overhead cooling unit controller 105 in a predetermined software protocol format, for example, in a predetermined software protocol format such as TCP, UDP, and FTP.

Specifically, when the plurality of cabinets are just opened, the linkage information, such as the air inlet and outlet temperature, the air volume, the air pressure and the like, or the water valve opening information of the overhead cooling unit, which is acquired by cooling the overhead unit controller 105 from the plurality of cabinets, the at least one fan backplane and the overhead cooling unit, respectively, is calculated according to the linkage information, and the corresponding instruction information is determined. For example, in step S202, the overhead cooling unit controller 105 in the cooling device 1 calculates the intake air temperature difference and the air volume difference between different types of cabinets, or the sum of the air volume of the fan walls of other cabinets except the first type of cabinet and the air volume of the fan back plate at the back thereof, the difference 1 compared with the air volume of the fan wall of the first type of cabinet, and the water valve opening of the overhead cooling unit, and determines the corresponding command information according to the intake air temperature difference and the air volume difference, the difference 1 and the water valve opening.
In step S203, the cooling apparatus 1 sends the instruction information to the switch, the at least one fan backplane, and the overhead cooling unit, respectively, so as to adjust at least one of the plurality of cabinets corresponding to the switch, the at least one fan backplane, or the overhead cooling unit, respectively. Specifically, in step S203, the cooling device 1 sends the instruction information determined in step S202 to the switch, and then adjusts the operating frequency of at least one of the multiple cabinets through the switch, so as to adjust the air inlet and outlet information of the at least one cabinet, such as the air volume, the air pressure, the air inlet and outlet temperature, or the fan rotation speed; the cooling device 1 sends the instruction information determined in step S202 to the at least one fan backplane respectively to adjust the operating frequency of the fan backplane, thereby achieving adjustment of air inlet and outlet information such as air volume, air pressure, air inlet and outlet temperature, or fan rotation speed of the at least one fan backplane; the cooling device 1 sends the instruction information determined in step S202 to the overhead cooling unit, where the overhead cooling unit includes a water path adjusting device, and the overhead cooling unit instructs the water path adjusting device to adjust the opening degree of the water valve of the overhead cooling unit according to the instruction information.
Wherein adjusting at least one of the plurality of cabinets corresponding to the switch 106, the at least one fan backplane 104, or the overhead cooling unit 102, respectively, comprises: an operating frequency of a fan wall of at least one of the plurality of cabinets; an operating frequency of the at least one fan backplate; a water valve opening of the overhead cooling unit. Specifically, in an initial situation, when the plurality of cabinets are just opened, in step S202, the cooling overhead unit controller 105 in the cooling device 1 determines corresponding instruction information according to the linkage information, such as the intake air temperature and the air volume difference, obtained in step S201, of the plurality of cabinets, for example, the instruction information is to open the fan back plate arranged at the back of the remaining cabinets, adjust the operating frequencies of the fan back plate and the fan walls of the remaining cabinets, and adjust the water valve opening of the overhead cooling unit, and then adjust the operating efficiency of the fan wall of at least one cabinet in the plurality of cabinets corresponding to the switch, the operating efficiency of the at least one fan back plate, or the water valve opening of the overhead cooling unit according to the instruction information; in the case of normal operation, after the plurality of cabinets are opened for a certain period of time, in step S202, the overhead cooling unit controller 105 in the cooling apparatus 1 calculates the sum of the air volume of the fan walls of the other cabinets except the first type cabinet and the air volume of the fan back panel at the back thereof, the difference 1 compared to the air volume of the first type of cabinet fan wall, and the water valve opening of the overhead cooling unit, determining corresponding instruction information according to the difference 1 and the water valve opening, where the instruction information is, for example, to adjust the operating frequency of the fan back plate and the fan walls of the other cabinets and to adjust the water valve opening of the overhead cooling unit, and the overhead cooling unit controller 105 in the cooling device 1 adjusts, according to the instruction information, the operating efficiency of the fan back plate of at least one cabinet of the multiple cabinets corresponding to the switch, the operating efficiency of the at least one fan back plate, or the water valve opening of the overhead cooling unit.
Wherein adjusting the operating frequency of the fan wall of at least one of the plurality of cabinets comprises: the switch acquires the command information sent by the overhead cooling unit controller; and forwarding the instruction information to at least one corresponding cabinet in the plurality of cabinets to adjust the operating frequency of the fan wall of at least one cabinet in the plurality of cabinets. Specifically, the part of the linkage information from the switch is obtained by the switch performing data collection on at least one of the multiple cabinets, when the operating frequency of the fan wall of at least one of the multiple cabinets is adjusted, the instruction information is firstly sent to the switch, the switch acquires the instruction information sent by the overhead cooling unit controller, and then forwards the instruction information to at least one of the multiple cabinets, and after the at least one of the multiple cabinets acquires the instruction information, the operating frequency of the fan wall of at least one of the multiple cabinets is adjusted according to the instruction information.
Here, in step S203, after the cooling device 1 adjusts at least one of the plurality of cabinets corresponding to the switch, the at least one fan backplane, or the overhead cooling unit, the cooling device 1 goes to perform step S201 again to obtain adjusted linkage information from the switch, the at least one fan backplane, and the overhead cooling unit again, then in step S202, the cooling device 1 determines corresponding instruction information by calculation according to the adjusted linkage information, and performs step S203 again, in step S203, the cooling device 1 sends the instruction information to the switch, the at least one fan backplane, and the overhead cooling unit respectively, and repeatedly adjusts and corrects the at least one of the plurality of cabinets corresponding to the switch, the at least one fan backplane, or the overhead cooling unit. Therefore, the overhead cooling control unit 105 adjusts at least one of the plurality of cabinets corresponding to the switch, the at least one fan backplane, or the overhead cooling unit according to the acquired linkage information, then acquires linkage information corresponding to at least one of the plurality of cabinets corresponding to the adjusted switch, the at least one fan backplane, or the overhead cooling unit, and dynamically adjusts at least one of the plurality of cabinets corresponding to the switch, the at least one fan backplane, or the overhead cooling unit according to the adjusted linkage information until the problem of uneven cooling and heating caused by cabinet mixing of the cooling device 1 is solved.
In the cooling method, fan back plates are arranged at the backs of other types of cabinets except a first type of cabinet in the plurality of cabinets of the cooling device 1, and the plurality of cabinets, the fan back plates and the top-mounted cooling unit are subjected to linkage control through a top-mounted cooling unit controller, so that the problem of uneven cooling and heating caused by mixed parts of different types of cabinets is solved, the cooling device 1 supports the mixed parts of different types of cabinets, the applicability of the cooling end of the top-mounted cooling unit is improved, the flexibility of cabinet deployment is improved, and in addition, the rotating speed of a fan of a cabinet fan wall or the fan of the current class and/or the opening degree of a water valve of the top-mounted cooling unit are adjusted, so that the two dimensions are cooperatively optimized, the control precision of a refrigeration system is improved, and the refrigeration energy consumption of.
Preferably, the plurality of cabinets includes two types of cabinets, wherein one fan back plate is disposed at each back of a second type of cabinet, and a rated wind pressure of a fan wall of the second type of cabinet is the smallest among the plurality of cabinets. Specifically, the first type of cabinet fan wall has a large air volume and a large air pressure, and the second type of cabinet fan wall has a small air volume and a small air pressure. Because the two types of cabinets are located in the same hot channel closed unit, the fan wall of the second type cabinet has overlarge running resistance and cannot smoothly exhaust air, and even hot air in the hot channel flows back to the second type cabinet, so that the inlet air temperature of the second type cabinet is seriously exceeded. And a fan back plate is quickly installed at the back of each cabinet of the second type of cabinet, and the OCU controller is accessed. The servers of the nodes of the first type and the second type of cabinets carry out data collection and processing on data such as air inlet temperature, fan rotating speed and the like through the switch 104, and the data are sent to the OCU controller in a certain software protocol form. The OCU controller sends out an instruction signal by calculating the inlet air temperature and the air volume difference of the fan walls of the first type cabinet and the second type cabinet. At least one of the cabinets receives the instruction signal and adjusts the running frequency of the fan wall, the fan back plate receives the instruction signal and adjusts the running frequency of the fan back plate, and the OCU control valve group receives the instruction signal and adjusts the opening of the water valve. The cooling device 1 and the cooling method implemented by the cooling device 1 solve the problem of uneven cooling and heating caused by the mixed part of the cabinet by arranging the fan back plate at the back of the second type cabinet and utilizing the strategy of linkage of the cabinet, the fan back plate, the overhead cooling unit and the overhead cooling unit controller.
