Description

Liquid-cooled data center test equipment and liquid-cooled data center test system

This application requires the priority of the Chinese patent application submitted to the China Patent Office on July 20, 2022, with the application number 202210851253.4 and the application name "Liquid-cooled data center test equipment and liquid-cooled data center test system". All its contents have been approved. This reference is incorporated into this application.

Technical field

The invention relates to the field of liquid-cooled data center verification test tools, and in particular to a liquid-cooled data center test equipment and a liquid-cooled data center test system.

Background technique

With the development of technologies such as the Internet, cloud computing, and artificial intelligence, the construction scale of data centers is becoming larger and larger, and power consumption is also increasing, accounting for 1% to 3% of the country's total annual electricity consumption. With a growth rate of 12%, data centers have been included in the country's list of high-energy-consuming industries. Electricity bills will be increased by 20%. The country and various localities have successively introduced power usage effectiveness (Power Usage Effectiveness, referred to as PUE) for newly built, renovated and expanded data centers. Low PUE indicates The original data centers using air-cooled servers are difficult to achieve low PUE requirements, so more and more data centers use liquid-cooled servers.

After the construction of the data center is completed, verification testing is usually required. The verification test is an in-depth review of the design and construction of the data center's HVAC and power supply systems. Through various tests on each system, it is found that the system is in the design and various faults and problems existing in the construction process to avoid losses caused by system failures after the data center is delivered and put into operation. Failure to conduct verification testing will bring unforeseen risks to the later operation of the data center.

In related technologies, data centers that use air-cooled servers use dummy loads to test each function of each system during testing. During the test process, the dummy loads convert electrical energy into heat energy and release it into the computer room environment. The heat dissipated into the environment is eventually absorbed. The computer room air conditioning system is vented to the outdoors. Liquid-cooled data centers are data centers that use coolant to cool IT equipment such as servers. Specifically, servers in liquid-cooled data centers are "bubbled" in cabinets filled with coolant, and the cooling provided by the coolant cooling system Liquid cooling, the coolant cooling system is the Coolant Distribution Units (CDU). The heat absorbed by the coolant cannot be dissipated through the computer room environment. Therefore, when testing the liquid-cooled data center, the dummy load must also be included. Soak in coolant. If this method is used for testing, the coolant will be contaminated, which will affect later use, and in severe cases, cause damage to the server. Therefore, most of the liquid-cooled data centers currently constructed do not conduct testing or use officially-used liquid-cooled servers to test CDU cooling and officially-used liquid-cooled servers. This testing method often fails to meet the usage requirements, and the test process is easily damaged. server.

It can be seen that data centers that currently use liquid-cooled servers do not have suitable testing equipment, resulting in the lack of adequate testing equipment for liquid-cooled servers in the existing technology. Technical issues that make testing in the data center inconvenient. In response to the above problems, no effective solution has yet been proposed.

The above information disclosed in the Background section is only provided to enhance understanding of the background of the technology described herein. Therefore, the Background Art may contain information that does not form the prior art known to those skilled in the art.

Detailed ways

In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only These are some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts should fall within the scope of protection of the present invention.

It should be noted that, as long as there is no conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

As shown in Figures 1 to 4, an embodiment of the present invention provides a liquid-cooled data center test equipment, which includes: a housing 1 with a closed installation cavity 100; a heat source 2, which is provided in the installation In the cavity 100; the heat exchanger 3 is arranged in the installation cavity 100 to exchange heat with the heat source 2. The heat exchanger 3 has a coolant inlet 31, a coolant outlet 32 and is connected with the coolant inlet 31 and the heat source 2. The coolant flow channel of the coolant outlet 32.

The liquid-cooled data center test equipment of the embodiment of the present invention includes a closed installation cavity 100 and a heat source 2 and a heat exchanger 3 installed in the installation cavity 100. In this way, the heat source 2 and the heat exchanger 3 are installed in the closed installation cavity 100. When the liquid-cooled data center test equipment of the liquid-cooled heat exchanger 3 is in use, connect the coolant inlet 31 of the heat exchanger 3 to the liquid supply port of the coolant supply system to be tested, and connect the coolant outlet of the heat exchanger 3 32 is connected to the liquid return port of the coolant supply system to be tested. Since the heat source 2 and the liquid-cooled heat exchanger 3 are arranged in the closed installation cavity 100, the heat emitted by the heat source 2 will be fully absorbed by the coolant in the heat exchanger 3, and the heated coolant will flow back. It is cooled by the coolant supply system to achieve thermal balance in the installation cavity 100, instead of spreading the heat to the computer room environment, causing the environment to heat up and affecting the test results. Combined with the heating power of heat source 2, the cooling capacity of the coolant supply system can be obtained, and then it can be tested whether the design of the coolant supply system meets the cooling demand. Moreover, during testing, the liquid-cooled data center test equipment can simulate a running liquid-cooled cabinet to facilitate various tests on the liquid-cooled data center, thereby helping to discover defects in the design and construction process of the liquid-cooled data center system. Various faults or defects, and then eliminate faults in a timely manner to avoid unnecessary losses caused by system failures after the liquid-cooled data center is delivered and put into operation. The liquid-cooled data center test equipment designed with the above-mentioned structure can simulate a running liquid-cooled cabinet to facilitate testing of the cooling capacity of the coolant supply system and other items of the liquid-cooled data center. It solves the problem of liquid cooling in the existing technology. Technical issues that make testing in the data center inconvenient.

Heat source 2, as the name suggests, is a component that can generate heat. You can usually choose an electric heater to simulate the heat emitted by the server during operation by emitting heat from the heat source, so it can be called a dummy load. In order to improve the heat exchange effect between the dummy load and the air so that it can better transfer heat to the coolant, the heat source 2 is provided with an air flow channel inside. Regarding the positional relationship between the heat source 2 and the heat exchanger 3, there can be a variety of arrangements, such as the two being in contact with each other, the two being spaced apart, one of the two being arranged around the other, and so on. The specific structural form of the heat exchanger 3 can also be in various forms, as long as the heat exchange effect can be achieved, such as coil type heat exchanger, fin type heat exchanger, etc. There can also be a variety of cooling liquid options, as long as the heat exchange effect can be achieved. It only needs to be able to absorb and release heat to achieve heat dissipation of the installation cavity 100. For example, it can be a special coolant for the coolant supply system, or it can be pure water.

It should be noted that the above-mentioned sealing is not limited to complete sealing. Due to production process defects, processing errors, etc., it is usually difficult to make the installation cavity 100 completely closed, and there may be a small amount of air due to some defects. leakage, but the purpose and direction of the design is to ensure better sealing of the installation cavity 100 and to avoid air circulation between the inside and outside of the housing 1 as much as possible.

In particular, at least part of the housing 1 is made of thermally insulating material. By making at least part of the housing 1 made of heat-insulating material, the heat-insulating effect of the housing 1 can be improved, thereby ensuring that the heat emitted by the heat source 2 can be limited in the installation cavity 100 and then more fully absorbed by the heat exchanger 3 , in this way, during the liquid cooling data center test, when the actual power consumption of the heat source 2 of all the test equipment cooled by the coolant supply system is adjusted to the same as the cooling capacity of the coolant supply system, cooling can be simulated The heat exchange capacity of the coolant supply system can be easily tested to see whether the coolant supply system meets the designed cooling demand.

It can be understood that in order to better simulate the heat exchange capacity of the coolant supply system, the better the thermal insulation of the housing 1 is, the more accurate the test results will be. On this basis, those skilled in the art can use various feasible methods. Technical means to improve the thermal insulation of the housing 1, such as improving its sealing, using better thermal insulation and/or thicker insulation materials to separate the installation cavity 100 packages and so on.

Please refer to Figure 1. The liquid cooling data center test equipment also includes: a fan 4, which is disposed in the installation cavity 100; a temperature detection element 5, which is disposed on a side close to the air inlet of the fan 4.

By arranging a fan in the installation cavity 100, the air flow in the installation cavity 100 can be enhanced, thereby improving the heat exchange performance of the heat exchanger 3, so that the heat emitted by the heat source 2 can be more fully absorbed by the heat exchanger 3. Here, Basically, by setting the temperature detection element 5 on the air inlet side of the fan 4, the air temperature circulating in the installation cavity 100 can be measured. The air temperature at the air inlet of the fan 4 can better reflect the temperature in the entire installation cavity 100. The comprehensive condition of the air temperature is used to better control the temperature condition in the installation cavity 100 and facilitate the testing process of the liquid-cooled data center. Specifically, here only the layout directions of the heat source 2 and the heat exchanger 3 and the layout directions of the heat source 2 and the fan 4 are restricted, but the distance between them is not limited. That is to say, the heat source 2 and the fan 4 are not limited. The heat exchanger 3 may be arranged in contact along the first direction, or may be arranged at intervals along the first direction. The heat source 2 and the fan 4 may be arranged in contact along the second direction, or may be arranged at intervals along the second direction. The temperature detection element 5 can be selected from a variety of specific forms, such as a thermometer and a temperature sensor.

Specifically, the heat source 2 and the heat exchanger 3 are arranged in sequence along the first direction, the fan 4 and the heat source 2 are arranged in sequence along the second direction, and the first direction is perpendicular to the second direction.

In this embodiment, the heat source 2 and the heat exchanger 3 are arranged along the first direction, and the fan and the heat source 2 are arranged along the second direction perpendicular to the first direction. In this way, although the wind blown by the fan 4 is not directly Blow onto the heat source 2 and the heat exchanger 3, but this arrangement is conducive to making the air in the installation cavity 100 better form a circulating air flow, which is conducive to strengthening the relationship between the heat source 2 and the heat exchanger 3. heat exchange. The above-mentioned first direction and second direction are only used to refer to two mutually perpendicular directions. Specifically, the first direction can have various choices, such as various horizontal directions and tilted directions at various angles. etc. Correspondingly, the second direction will also change accordingly.

In order to further improve the driving effect of the fan 4 on the air in the installation cavity 100 and improve the heat exchange capacity, the inner surface of the installation cavity 100 has a smooth structure, and there can be multiple fans 4. In this way, the air can be driven more smoothly during the installation of the housing 1. Circulation in the cavity 100 is beneficial to improving the heat exchange effect between the heat source 2 and the heat exchanger 3 .

As a preferred embodiment, there are a plurality of heat sources 2 , any heat source 2 is arranged sequentially with the heat exchanger 3 along the first direction, and the plurality of heat sources 2 are spaced apart along the direction perpendicular to the first direction.

Based on the above arrangement of the heat source 2 and the heat exchanger 3, by arranging multiple heat sources 2 and designing the multiple heat sources 2 to be spaced apart in a direction perpendicular to the first direction, through The circulating airflow formed by driving the fan 4 can better pass through the gaps between the heat sources 2, thereby more fully exchanging heat with each heat source 2, and improving the heat exchange performance between the heat sources 2 and the air. Specifically, the liquid-cooled data center test equipment includes a support frame 6. The support frame 6 has a plurality of support parts spaced apart along the second direction, and a plurality of heat sources 2 are installed on the plurality of support parts in one-to-one correspondence.

As shown in Figure 3, the liquid cooling data center test equipment also includes: a controller 7, a fan 4, a temperature detection element 5 and multiple heat sources 2 are all connected to the controller 7. In this way, by using the controller 7, the working status of each heat source 2 can be controlled, the working status of the fan 4 can be controlled, and the temperature data detected by the temperature detection element 5 can be obtained, which is beneficial to convenience. In order to more accurately control the working conditions of the liquid-cooled data center test equipment, in the embodiment of Figure 3, the controller 7 is set on the protective door 8. As a preferred embodiment, the liquid-cooled data center test equipment also includes an alarm component (not shown in the figure). The alarm component is connected to the controller 7. When a certain component of the liquid-cooled data center test equipment fails, the controller 7. The alarm component can be controlled to emit alarm signals in the form of sound, light, vibration, etc. to prompt the operator to maintain or replace faulty components in a timely manner, thereby ensuring the reliability of the test results.

Specifically, as shown in FIG. 1 , when the liquid-cooled data center test equipment is in use, the cooling liquid inlet 31 and the cooling liquid outlet 32 are spaced apart in the height direction, and the cooling liquid outlet 32 is located above the cooling liquid inlet 31 .

That is to say, when the liquid-cooled data center test equipment is placed in normal use, the coolant outlet 32 is above the coolant inlet 31. In this way, when the coolant flows through the heat exchanger 3 for heat exchange, the coolant is cooled at low temperature. The liquid flows in from the coolant inlet 31 below, and the high-temperature coolant flows out from the coolant outlet 32 above, which can better adapt to the influence of temperature on the density of the coolant and ensure a smoother flow of coolant in the heat exchanger 3. It is beneficial to ensure the heat exchange effect of the heat exchanger 3. It should be noted that in actual implementation, the second direction may be consistent with the height direction, or may be inconsistent with it. Specifically, the second direction is a direction perpendicular to the first direction. Therefore, there are countless choices for the second direction, such as a direction perpendicular to the paper surface, a direction consistent with the height direction, etc., but the height direction is the only one. , which is not only perpendicular to the first direction, but also perpendicular to the direction perpendicular to the paper surface.

As shown in Figures 1 to 3, the housing 1 is provided with an operating port, which connects the installation cavity 100 with the external space of the housing 1. The housing 1 is also provided with a protective door 8, which is movable relative to the housing 1. Set up to cover or expose the operating port.

By arranging the operation port and the protective door 8 on the housing 1, the components inside the housing 1 can be easily operated and maintained by opening the protective door, which facilitates the use of the equipment. In order to more conveniently realize the control of various positions in the installation cavity The components are maintained for maintenance. In this embodiment, there are two operation openings, and the two operation openings are correspondingly arranged on the opposite sides of the housing 1. There are two corresponding protective doors 8, and the two protective doors 8 are connected with each other. Each operation port is set in one-to-one correspondence.

As shown in Figures 3 and 4, the housing 1 is provided with an observation window 9 made of light-transmitting material to observe the inside of the installation cavity 100 through the observation window 9, thereby facilitating the test operator to inspect the liquid-cooled data center test equipment. Visually observe the operation of each internal component. The housing 1 is provided with a power distribution connection port 10 for supplying power to the liquid cooling data center test equipment through the power distribution connection port 10 .

In addition, embodiments of the present invention also provide a liquid-cooled data center testing system, which includes: a cooling liquid supply system, the cooling liquid supply system has a liquid outlet and a liquid return port; a plurality of the above-mentioned liquid-cooled data center testing equipment , the coolant inlets 31 of multiple liquid-cooled data center test equipment are connected to the liquid outlets of the coolant supply system, and the coolant outlets 32 of multiple liquid-cooled data center test equipment are connected to the liquid return ports of the coolant supply system. .

The embodiment of the present invention provides a test load equipment used in a liquid-cooled data center. The support frame 6 is a rack-type cabinet used to place a rack-type dummy load (heat source 2) for testing. The support frame 6 The left side is the cold air inlet channel for the rack-type dummy load, and the cooling coil (heat exchanger 3) is installed on the right side of the support frame. The cooling coil is used to exhaust the hot air of the rack-type dummy load using cooling water or coolant. Cool down, so that the power supply system of the server in the liquid-cooled server cabinet can be tested. If the coil is cooled by cooling water, the corresponding data center cold source system can be tested, such as If coolant is used for cooling, the corresponding CDU coolant cooling system can be tested. The working principle of the liquid-cooled data center test equipment is that the heat generated by the rack-type dummy load is transferred to the cooling medium (coolant) through the circulating air and cooling coils inside the test equipment, and then the cooling medium is dispersed to the outdoors. Fan 4 provides continuous circulation power for circulating air. The cooling coil is provided with a coolant inlet 31 and a coolant outlet 32. The inlet is set at the bottom of the heat exchanger 3, and the outlet is set at the upper part of the heat exchanger 3. The cooling medium enters the cooling coil through the coolant inlet 31 at the bottom and flows through the false cooling coil. The hot air from the load row undergoes heat exchange, and the hot exhaust air is cooled down into cold air. The cooling medium is heated by the hot exhaust air and is supplied to the outside of the test equipment through the upper coolant outlet 32, and then is dispersed to the outdoors by the CDU or data center cooling source system. Environment. There are openable sealed access doors (protection door 8) on both sides of the test equipment. The access door is mainly used for replacement and maintenance of internal components and equipment. The access door is provided with an observation hole (observation window 9) and a control panel (controller 7). ), the observation hole facilitates testers to observe the internal operating status of the equipment. The main function of the control panel is to start and stop the rack-type dummy load and fan 4 in the test equipment. It can also control the number of rack-type dummy loads opened according to the actual rated test power. The test requires manual control to start and stop the rack-type dummy load. A temperature sensor is set at the entrance of the fan 4 in the equipment. When the fan 4 and the rack-type dummy load in the equipment fail, an alarm can be issued through the control panel. The tester can monitor the interior from the control panel. Equipment operating status.

By adopting the above structural design, the heating element and the cooling element form a small closed environment with balanced heat and cold. In this closed environment, the internal air is continuously sent through the fan 4 to send the heat generated by the energization of the dummy load into the cooling coil for cooling. The cold and heat are balanced in a small closed environment, without causing heat diffusion in the computer room environment to cause the environment to heat up and affect the test operation. In this way, the power supply and cooling system of the liquid-cooled data center can be tested. The small closed environment is similar to the computer room environment used to place servers in traditional air-cooled server data centers. Therefore, dummy loads can be used to simulate the operation of servers in liquid-cooled server cabinets, and Test whether the power supply system of the liquid-cooled server cabinet meets the design requirements, and the CDU serves as the cooling equipment of the liquid-cooled server cabinet. When the actual power consumption of the dummy loads in all the liquid-cooled server cabinets it supplies is adjusted to be equal to the cooling power of the CDU When the quantities are the same, the heat exchange capacity of the CDU equipment can be simulated and whether the CDU equipment meets the designed cooling demand can be verified.
