Description

Technical Field

[0001] The present invention relates to a rack-type loading device.

Background Art

[0002] An air conditioning test conducted in a data center for installing, operating, etc. various computers and data communication devices is a practical process for confirming the heat management in the data center and the effect of the cooling system, and maintaining an optimal temperature and temperature environment.

[0003] An example of a typical air conditioning test conducted in a data center will be described below.

[0004] (1) Monitoring Test First, temperature, humidity, air flow, power consumption, etc. are measured and recorded in different areas within the data center. This is collected in real time using smart sensors and monitoring systems.

[0005] (2) Measurement of Abnormal Temperature Distribution If there is a temperature bias or non-uniformity within the data center, this problem is identified. The appropriateness of hot aisles and cold aisles and the influence due to the arrangement of server racks are investigated and corrected.

[0006] (3) Measurement of Cooling Effect The amount and temperature of the cold air supplied from the cooling device are measured to evaluate the effect of the cooling system. Thereby, the efficiency of the cooling system and the control of the temperature environment within the data center are evaluated.

[0007] (4) Simulation of Abnormal Load A state of a sudden increase in load within the data center is simulated. For example, a sudden increase in traffic or high-load computational work is mimicked to confirm whether the cooling system functions reliably under these conditions.

[0008] (5) Optimization of Cooling Strategy Based on the test data, define actions to optimize the cooling strategy of the data center. This includes adjusting the cooling equipment, changing the wind direction and air volume, improving hot aisle / cold aisle, etc.

[0009] (6) Evaluation of energy efficiency Evaluate the energy efficiency of the data center based on the test results. Verify the power consumption for cooling and the power savings due to appropriate temperature settings, etc.

[0010] (7) Settings for automatic control and monitoring Set the automatic control and monitoring functions of the system so that it can quickly respond to environmental changes within the data center. Provide an alert and warning mechanism as needed.

[0011] Problems and solutions of the air conditioning test in the data center By regularly conducting these air conditioning tests, maintain the efficiency and stability of the cooling system of the data center, and identify and solve operational problems in advance.

[0012] The air conditioning tests conducted in the data center have been carried out as part of the commissioning (trial operation) before the handover of the data center.

[0013] Before the state where the server is installed, various situations assumed by using a simulated load test device for the heat quantity in the state where the server is installed and operating are reproduced, and a performance test of the air conditioning equipment is conducted.

[0014] The load device used at this time is a load device called a big loader with a load capacity of 50KW to 150KW. After installing it in the cold aisle, it generates the heat quantity emitted from the server.

[0015] However, in the case of the load device, not only does one load device generate the heat quantity equivalent to that of hundreds of servers, but also a stronger air volume is discharged from one location of the load device than the air volume discharged from the server. Therefore, it is necessary to deal with heat accumulation and adjust the installation position of the load device.

[0016] In addition, since it is necessary to manually operate a plurality of installed load devices, it is also necessary to deploy a large number of skilled staff.

[0017] In addition, since a large amount of heat is generated at one location in the load device, a server-type load device may be used. However, since the server-type load device has a load capacity of 2KW to 5kW, it is installed in the cold aisle and discharged to the hot aisle in the same way as when a server is installed.

[0018] Furthermore, since the capacity of this server-type load device is small, the number of units for the air conditioning test increases accordingly. For this reason, there are also problems that power receiving cable arrangement and control power supply cable wiring are required, and furthermore, a great deal of labor is required for setting.

[0019] In Patent Document 1, there is a load system including a resistance part including a resistor, a communication terminal, and a communication part that performs wireless communication with this communication terminal. The communication part transmits information regarding the on / off state of the load test device to the communication terminal via wireless communication, and receives a signal regarding an instruction to operate the load test device from the communication terminal via wireless communication. The load test device is used to perform a load test of air conditioning equipment for cooling a computer server, etc. and includes a communication terminal that performs wireless communication with the load test device. Software for displaying an on / off state display pattern is installed in the communication terminal. The on / off state display pattern has a relay on / off state display area indicating the on / off state of at least the plurality of resistor groups in the resistor part among the relays in the load test device, and a load test state display area indicating the state of the load test of the load test device. A load system is proposed in which, in response to an operation of the relay on / off state display area, the on / off state of at least the relays corresponding to the plurality of resistor groups in the resistor part in the load test device is switched.

[0020] However, in the case of the load system of Patent Document 1, it has a resistance section provided with a plurality of resistor groups including resistors, and when the communication between the communication section and the communication terminal is disconnected, in the load test apparatus, it corresponds to the plurality of resistor groups in the resistance section, and at least one of those in the on state is configured to turn off.

[0021] For this reason, in the case of the load system of Patent Document 1, it includes the problems that the load wiring becomes complicated and a large number of personnel are still required for the plurality of resistor groups.

[0031] The rack-type load device of the present invention is of a type that assumes a future server and houses it in a rack, aiming to provide more efficient and effective means. It can provide a similar environment to the original server with multiple servers integrated as a single load device, and is characterized by facilitating transportation, wiring, and personnel reduction. The rack-type load device is configured, for example, with a maximum of 20 KW per unit (0.5 KW × 4 stages × 10 units), and is realized by a configuration of a rack-type load device that can be arbitrarily selected and operated for each unit (0.5 KW × 4 stages).

Embodiment

[0032] Embodiments of the present invention will be described in detail below with reference to the respective drawings.

[0033] The rack-type load device according to an embodiment of the present invention will be described with reference to FIG. 1.

[0034] The rack-type load device 01 according to this embodiment is a system for wired control and monitoring of a test device in order to conduct comprehensive tests such as unit tests and load performance tests of the data center data hall air conditioning equipment, and includes a control terminal PC2 having a wireless or wired function.

[0035] For the load devices 05 and the like, the rack-type load device 01 is configured such that voltage is supplied from a lower-level device and the control terminal PC2 is connected so that instructions can be sent from the control terminal PC2 to each load device 05. This simplifies communication and improves communication speed and quality. In addition, each load device 05 has a unique address set, and is configured such that an arbitrary group number and device number can be set from the control terminal PC2.

[0036] In addition, load circuit setting information is shared, and the load circuit is dynamically controlled into a control device according to a load fluctuation command from the middle-level monitoring system. The control terminal PC2 can display the layout of each load device 05 externally attached and installed to the load device.

[0037] That is, if each load device 05 is normal, it is configured to display in green, if there is any abnormality, it is configured to display in orange, and if it has reached a dangerous state, it is configured to display in red and emit a warning sound. When selecting the load device whose color has changed from green display to orange display, it is configured to display abnormality detection information. In addition, it is also possible to perform settings such as grouping according to the test content and device numbering.

[0038] Next, with reference to FIGS. 2(A) and 2(B), the basic configuration of the device body 21 in the rack-type load device 01 according to the embodiment of the present invention will be described. FIG. 2(A) shows a schematic structure seen from the front, and FIG. 2(B) shows a schematic structure seen from the side.

[0039] In FIG. 2(A), 10 intake fans 22 are arranged vertically and arranged in 3 rows, for a total of 30, and the inside of the device body 21 having such a structure is ventilated. Also, in FIG. 2(B), 10 units of 0.5 KW × 4 stages are stacked on the device body 21, and a shared bus bar T.S.R shared by each rack R1 to R10 stacked in FIG. 2(B) is provided, making it possible to easily cope with the addition of loads. Note that 23 is a magnetic switch.

[0040] Next, FIG. 3 is an electrical circuit diagram. The same circuit has a manual switch 30 that is manually opened and closed, and drives the intake fan 22 via a fan bracket 54 that supports the DC intake fan 22 in FIG. 5 described later. Also, for the heater 42 of the heater bracket 48, three-phase AC power is transmitted from the bus duct to the three-phase magnetic switch 23, and the magnetic switch 23 is driven to turn on and off.

[0041] In addition, auxiliary contacts are attached to the magnetic switch 23 in the same circuit. When the magnetic switch 23 operates differently (such as chattering), this is detected and operation correction is performed, and it is provided in all of the racks R1 to R10.

[0042] Next, FIGS. 4(A) to 4(D) are perspective views of the structure of the heater mass body 41 in the rack-type load device 01 according to an embodiment of the present invention, showing the separated components. The heater mass body 41 in FIG. 4(A) has several heaters 42 installed between the opposing side plates 43, and warm air is discharged from its exhaust port 47. This warm air mixes with the cold air sent from the intake port 46 by the intake fan 22 from a direction substantially perpendicular to the installed heater 42 and is exhausted as moderately warm air. As a result, the exhaust is temperature-adjusted through the exhaust net 45 in FIG. 4(D).

[0043] As shown in FIG. 4(B), the heaters 42 are arranged alternately so as not to be in the same plane between adjacent ones, and consideration is given to making the temperature distribution of the environment, including the periphery, uniform.

[0044] Next, FIG. 5 is a plan view showing the rack body 11 incorporating the heater mass body 41 also in a planar manner. The intake fan 22 is mounted on the fan bracket 54 of the heater mass body 41, and the magnet switches 23 installed on the side walls of the rack body 11 are respectively connected to the shared bus bar T.S.R via the heater cables 52.

[0045] The shared bus bar T.S.R is configured by being respectively connected to the terminal block 55 via the cables 56, and a part of the main cable 56 is connected to the CT / instrument transformer 57 for measuring voltage, current, and power. 58 is an AC100V connector, and a control / baseboard space 59 is secured in its vicinity.

[0046] FIGS. 6(A) and 6(B) show an image of installing four series-connected connection rack bodies 60 and three series-connected connection rack bodies 61. As is clear from the figure, since the connection positions to the bus duct 81 on the side of the aggregating device body 70 are unified, the wiring work can be simplified and labor-saving. 81 is a bus duct.

Industrial Applicability

[0047] The present invention is not limited to the above-described embodiments. For example, in the above-described embodiments, the case of time series mainly according to wired connection has been mainly described, but it is also conceivable to configure it to be executed wirelessly partially or entirely according to the processing ability of the device that executes the processing, and of course various applications are possible.
