Prefabricated integrated air and liquid cabinet

[0001] This application claims priority to Chinese patent application filed on November 26, 2024, application number 202422895137.X, entitled “Prefabricated integrated air-liquid cabinet”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of cabinet technology, and in particular to prefabricated integrated air-hydraulic cabinets. Background Technology

[0003] With the development of data centers, the density of single racks continues to increase. Traditional air-cooling methods can no longer meet the heat dissipation requirements, and energy efficiency cannot meet relevant requirements. Future data centers face multiple challenges in energy consumption and heat dissipation, and liquid cooling solutions have become the development trend of future data centers. Cold plate liquid cooling, as a relatively mature liquid cooling method, is widely used.

[0004] In practical applications, liquid cooling and air cooling are often used in combination. When the two are used together, the on-site configuration is complicated, requiring multiple pipeline channels and on-site completion of power supply and distribution, pipeline system wiring and connection work. Summary of the Invention

[0005] This application provides a prefabricated integrated air and liquid control cabinet to simplify wiring and piping work and reduce on-site installation and configuration work.

[0006] This application provides a prefabricated integrated air-liquid cooling cabinet, including: a power distribution unit (PDU), rack-mounted cooling distribution units (CDUs), a liquid distribution unit, an air-liquid heat exchanger, a monitoring platform, and multiple monitoring units integrated within the cabinet.

[0007] The PDU is connected to a power source through the power supply interface provided by the cabinet, and supplies power to at least the CDU, the air-liquid heat exchanger, the cold plate liquid-cooled server installed in the cabinet, and the monitoring platform.

[0008] The CDU has a primary side connected to a cold source via a heat exchange interface provided by the cabinet, and a secondary side providing cooling medium for the liquid distribution unit and the air-liquid heat exchanger.

[0009] The liquid distribution unit is connected to the cold plate liquid cooling server and is used to provide the cooling medium provided by the CDU to the cold plate liquid cooling server.

[0010] The air-liquid heat exchanger is used to dissipate heat from the cabinet;

[0011] The monitoring platform is used to obtain the status parameters of the cabinet through the multiple monitoring units.

[0012] In the aforementioned cabinet, the entire cabinet is prefabricated, integrating the connections between various internal parts. The entire cabinet only provides the PDU power supply interface and the CDU primary side interface to the outside. During on-site installation, only the power supply interface, the CDU primary side interface, and the liquid cooling pipeline connection between the liquid distribution unit and each cold plate liquid-cooled server need to be completed, which greatly simplifies the wiring and piping work and reduces on-site installation and configuration work.

[0013] In addition, the cabinet provided in this application embodiment has a monitoring platform that obtains the cabinet's status parameters through multiple monitoring units. The monitoring platform can monitor the cabinet's status. At the same time, the cooling medium for the liquid distribution unit and the air-liquid heat exchanger is provided by the CDU. The CDU can be used to easily adjust the flow rate and temperature of the cooling medium provided to the liquid distribution unit and the air-liquid heat exchanger to suit application scenarios with different power densities.

[0014] In one possible implementation, the air-liquid heat exchanger includes a heat dissipation coil.

[0015] In the aforementioned cabinet, the air-liquid heat exchanger only includes heat dissipation coils, which use the fans of the cold plate liquid-cooled server to dissipate heat from the cabinet. No fans are required, making it suitable for scenarios with low power density and saving energy.

[0016] In one possible implementation, the air-liquid heat exchanger further includes at least one fan.

[0017] In the aforementioned cabinet, the air-liquid heat exchanger may also include one less fan. While using the fan of the cold plate liquid-cooled server to dissipate heat from the cabinet, it also assists and accelerates the cooling of the cabinet through the fan. It is suitable for scenarios with medium or high power density.

[0018] In one possible implementation, the air-liquid heat exchanger is integrated into the rear door frame of the cabinet.

[0019] In the aforementioned cabinets, the air-liquid heat exchanger is integrated into the rear door frame of the cabinet. In other words, the rear door containing the air-liquid heat exchanger is used instead of the traditional cabinet rear door, eliminating the need for a separate cabinet to install the air-liquid heat exchanger and saving space in the data center.

[0020] In one possible implementation, the secondary liquid outlet of the CDU is connected to the inlet of the liquid distribution unit and the inlet of the air-liquid heat exchanger via a first control valve.

[0021] The outlet of the air-liquid heat exchanger is connected to the inlet of the liquid distribution unit and the secondary side return port of the CDU via a second control valve.

[0022] The outlet of the liquid distribution unit is connected to the secondary side return port of the CDU.

[0023] In the aforementioned cabinet, the secondary side liquid outlet of the CDU is connected to the inlet of the liquid distribution unit and the inlet of the air-liquid heat exchanger via a first control valve. The outlet of the air-liquid heat exchanger is connected to the inlet of the liquid distribution unit and the secondary side liquid return port of the CDU via a second control valve. By controlling the first and second control valves, the cooling mode of the cabinet can be flexibly switched and the air-liquid ratio can be adjusted to provide different cooling capacities.

[0024] In one possible implementation, the cabinet further includes:

[0025] The controller is used to control the first control valve and the second control valve to switch the heat dissipation mode of the cabinet.

[0026] In one possible implementation, the combined heat dissipation mode includes a first heat dissipation mode, a second heat dissipation mode, and a third heat dissipation mode;

[0027] In the first heat dissipation mode, the secondary side liquid outlet of the CDU is connected to the inlet of the air-liquid heat exchanger, the outlet of the air-liquid heat exchanger is connected to the inlet of the liquid distribution unit, and the outlet of the liquid distribution unit is connected to the secondary side liquid return port of the CDU.

[0028] In the second heat dissipation mode, the secondary side liquid outlet of the CDU is connected to the inlet of the air-liquid heat exchanger and the inlet of the liquid distribution unit, respectively; the outlet of the air-liquid heat exchanger is connected to the inlet of the liquid distribution unit; and the outlet of the liquid distribution unit is connected to the secondary side liquid return port of the CDU.

[0029] In the third heat dissipation mode, the secondary side liquid outlet of the CDU is connected to the inlet of the air-liquid heat exchanger and the inlet of the liquid distribution unit, respectively, and the outlet of the air-liquid heat exchanger and the outlet of the liquid distribution unit are both connected to the secondary side liquid return port of the CDU.

[0030] In the aforementioned cabinet, in the first cooling mode, the air-liquid heat exchanger and the liquid distribution unit are connected in series, and the cooling medium first passes through the air-liquid heat exchanger and then through the liquid distribution unit. In the second cooling mode, the air-liquid heat exchanger and the liquid distribution unit are connected in series, and the CDU provides cooling medium to the liquid distribution unit. In the third cooling mode, the air-liquid heat exchanger and the liquid distribution unit are connected in parallel, and the cooling medium passes through both the air-liquid heat exchanger and the liquid distribution unit. The three cooling modes can provide different cooling capacities and can be flexibly switched according to the power consumption requirements of the cabinet to save energy.

[0031] In one possible implementation, the cabinet further includes a touch screen connected to the monitoring platform for configuring and / or displaying the status parameters of the cabinet.

[0032] In one possible implementation, the display screen is mounted on the front door of the cabinet.

[0033] In the aforementioned cabinet, the display screen is connected to the monitoring platform. The display screen can show the status parameters of the cabinet, which allows maintenance personnel to understand the status of the cabinet more intuitively.

[0034] In one possible implementation, the cabinet further includes a drip tray disposed at the bottom of the cabinet, wherein a water immersion sensor is disposed within the drip tray for detecting whether there is accumulated liquid in the drip tray.

[0035] In the aforementioned cabinet, by installing a drip tray at the bottom of the cabinet and a water immersion sensor to detect whether there is liquid accumulation in the drip tray, it is possible to monitor whether the cabinet is leaking. Attached Figure Description

[0046] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] In the description of the embodiments of this application, unless otherwise stated, " / " means "or". For example, A / B can mean A or B. The "and / or" in the text is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of this application, "multiple" means two or more.

[0048] In the following text, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0049] Before introducing the prefabricated integrated air-liquid cabinet provided in the embodiments of this application, the technical background of the embodiments of this application will be described in detail for ease of understanding.

[0050] With the development of data centers, the density of single racks continues to increase. Traditional air-cooling methods can no longer meet the heat dissipation requirements, and energy efficiency cannot meet relevant requirements. Future data centers face multiple challenges in energy consumption and heat dissipation, and liquid cooling solutions have become the development trend of future data centers. Cold plate liquid cooling, as a relatively mature liquid cooling method, is widely used.

[0051] In practical applications, liquid cooling and air cooling are often used in combination. However, the following drawbacks exist when using them together:

[0052] First, the on-site configuration is complicated, requiring the configuration of multiple pipeline channels, and the on-site completion of the wiring and connection work for the power supply and distribution and pipeline systems.

[0053] Second, the lack of an integrated monitoring and control platform makes it difficult to manage and intelligently control power supply and distribution, as well as air-cooled and liquid-cooled data in a one-stop manner.

[0054] Third, the air-liquid and liquid cooling systems are separated, each requiring an independent liquid cooling system. This results in cumbersome on-site engineering layout, a single air-liquid ratio control method, low level of control intelligence, and significant losses.

[0055] In view of this, the embodiments of this application provide a prefabricated integrated air-liquid cooling cabinet. By prefabricating the entire cabinet, the connections between the various parts inside the cabinet are integrated. The entire cabinet only provides the PDU power supply interface and the CDU primary side interface to the outside. During on-site installation, only the power supply interface, the CDU primary side interface, and the liquid cooling pipeline connection between the liquid distribution unit and each cold plate liquid-cooled server need to be completed, which greatly simplifies the wiring and piping work and reduces on-site installation and configuration work.

[0056] In addition, the cabinet provided in this application embodiment has a monitoring platform that obtains the cabinet's status parameters through multiple monitoring units. The monitoring platform can monitor the cabinet's status, and the PDU can uniformly manage the cabinet's power supply and distribution. The cooling medium for the liquid distribution unit and the air-liquid heat exchanger is provided by the CDU. The CDU can easily adjust the flow rate and temperature of the cooling medium supplied to the liquid distribution unit and the air-liquid heat exchanger to suit application scenarios with different power densities.

[0057] After introducing the background technology of the embodiments of this application, the prefabricated air-liquid integrated cabinet provided by the embodiments of this application will be described in detail below with reference to specific embodiments.

[0058] Referring to Figure 1, which is a prefabricated integrated air-liquid cabinet in an embodiment of this application, it includes: a PDU 10, a rack-mounted CDU 11, a liquid distribution unit 12, an air-liquid heat exchanger 13, a monitoring platform 14, and multiple monitoring units integrated within the cabinet. Figure 1(c) is an enlarged view of the liquid distribution unit 12 in Figure 1(b).

[0059] PDU 10 is connected to a power supply via the power supply interface provided by the rack, and supplies power to at least CDU 11, air-liquid heat exchanger 13, cold plate liquid-cooled server installed in the rack, and monitoring platform 14.

[0060] CDU 11 connects to the cold source on the primary side via the heat exchange interface provided by the cabinet, and provides cooling medium to the liquid distribution unit 12 and the air-liquid heat exchanger 13 on the secondary side.

[0061] It should be noted that the CDU can be installed at the bottom of the rack, without occupying server room space. The primary side of the CDU refers to the side where the CDU exchanges heat with the outdoor cold source, and the secondary side refers to the side where the CDU exchanges heat with the liquid distribution unit 12 and the air-liquid heat exchanger 13 inside the rack. The cooling medium mentioned in this application embodiment can be deionized water, ethylene glycol, propylene glycol, etc., and this application embodiment does not limit this.

[0062] The liquid distribution unit 12 is connected to the cold plate liquid cooling server and is used to provide the cooling medium provided by CDU 11 to the cold plate liquid cooling server. When there are multiple cold plate liquid cooling servers, the liquid distribution unit 12 distributes the cooling medium provided by CDU 11 to each cold plate liquid cooling server. The specific distribution method is not limited in this embodiment.

[0063] The air-liquid heat exchanger 13 is used for heat dissipation of the cabinet.

[0064] In practical implementation, the air-liquid heat exchanger 13 can be integrated into the rear door frame of the server rack, that is, using a rear door containing the air-liquid heat exchanger instead of a traditional server rack rear door to save data center space. The air-liquid heat exchanger 13 may consist only of a cooling coil, using the fans of the cold-plate liquid-cooled server to dissipate heat from the server rack, eliminating the need for a separate fan, making it suitable for scenarios with low power density and saving energy. Alternatively, the air-liquid heat exchanger 13 may include a cooling coil and at least one fan, which, in addition to using the fans of the cold-plate liquid-cooled server to dissipate heat from the server rack, assists and accelerates heat dissipation, making it suitable for scenarios with medium or high power density.

[0065] In one example, as shown in Figure 2, a heat exchanger for air-liquid heat exchange is installed on the rear door panel of the cabinet, including heat exchange coils and four fans 20.

[0066] The monitoring platform 14 is used to acquire the status parameters of the cabinet through multiple monitoring units. These monitoring units, not shown in Figure 1, can be various types of sensors or metering devices, such as temperature sensors, pressure sensors, flow sensors, door status sensors, flow meters, and electrically controlled valves.

[0067] It should be noted that the status parameters of the cabinet include, but are not limited to: cabinet internal temperature, pressure difference between the inside and outside of the cabinet, PDU power supply and distribution information, temperature of the cooling medium supplied by the CDU, temperature of the cooling medium returning to the CDU, valve opening of the control valve (the first control valve and the second control valve mentioned in the embodiments of this application), flow rate and temperature of the cooling medium in the pipeline, fan speed (fan in the air-liquid heat exchanger 13), fan air supply temperature, and cabinet rear door temperature, etc.

[0068] To more intuitively display the status parameters of the cabinet, the cabinet provided in this embodiment further includes a touch display screen 15, connected to the monitoring platform 14, for configuring and / or displaying the status parameters of the cabinet. Specifically, the touch display screen can be a display screen with a human machine interface (HMI).

[0069] As shown in Figure 3, the touch display screen 15 can be installed on the front door of the cabinet, specifically at any location on the front door. Figure 3 is for illustrative purposes only. Of course, in other embodiments of this application, the touch display screen 15 can also be installed in other locations within the cabinet.

[0070] In specific implementation, to monitor whether the cabinet is leaking liquid, the cabinet also includes a drip tray located at the bottom of the cabinet. The drip tray contains a water immersion sensor to detect whether there is liquid accumulation in it. This water immersion sensor can trigger an alarm when it detects liquid accumulation in the drip tray. Of course, in other embodiments of this application, upon receiving an alarm, the monitoring platform 14 or the central control platform connected to the monitoring platform 14 can also control the secondary side of the CDU to stop supplying cooling medium to the heat sink and / or the distribution unit.

[0071] The cabinet provided in this embodiment uses a cooling unit (CDU) to supply cooling medium to both the liquid distribution unit and the air-liquid heat exchanger. The specific connection structure is shown in Figure 4. The secondary-side outlet of the CDU is connected to the inlet of the liquid distribution unit and the inlet of the air-liquid heat exchanger via a first control valve 41. The outlet of the air-liquid heat exchanger is connected to the inlet of the liquid distribution unit and the secondary-side return port of the CDU via a second control valve 42. The outlet of the liquid distribution unit is connected to the secondary-side return port of the CDU. The first and second control valves can be solenoid valves, etc., and this embodiment does not limit their use.

[0072] Specifically, the cabinet also includes a controller, which controls the first control valve and the second control valve under the control of a pre-configured control algorithm to adjust the heat dissipation mode of the cabinet, thereby achieving optimal distribution of the cooling medium and reducing energy consumption.

[0073] The controller can be a microcontroller, processor, digital signal processing chip, etc. It can be integrated with the monitoring unit, that is, the monitoring and control functions are implemented by the monitoring unit. Alternatively, it can be set up separately from the monitoring unit. This application does not limit this.

[0074] In practice, the air-liquid heat exchanger and the liquid distribution unit share a common cold source, with the cooling medium provided by the CDU. A first control valve and a second control valve are installed in the connecting pipelines of the CDU, the air-liquid heat exchanger, and the liquid distribution unit. Several temperature sensors and several flow meters can also be installed to obtain the temperature and flow rate of the cooling medium in the pipeline.

[0075] In practical applications, the controller can adjust the heat dissipation mode of the cabinet by controlling the first and second control valves according to the temperature and flow rate of the cooling medium in the pipeline under the control of the pre-configured control algorithm. That is, it can adjust the flow ratio (also known as the air-liquid ratio) of the air-liquid heat exchanger and the liquid distribution unit to suit the actual power consumption requirements of the cabinet.

[0076] In practical applications, the heat dissipation modes include the first heat dissipation mode, the second heat dissipation mode, and the third heat dissipation mode. The three heat dissipation modes are explained below with reference to Figures 5-7.

[0077] As shown in Figure 5, in the first heat dissipation mode, the secondary side liquid outlet of the CDU is connected to the inlet of the air-liquid heat exchanger, the outlet of the air-liquid heat exchanger is connected to the inlet of the liquid distribution unit, and the outlet of the liquid distribution unit is connected to the secondary side liquid return port of the CDU.

[0078] In this heat dissipation mode, the cooling medium first passes through the air-liquid heat exchanger and then through the liquid distribution unit, and the cooling medium is recycled. This mode is suitable for applications with low power density.

[0079] As shown in Figure 6, in the second heat dissipation mode, the secondary side liquid outlet of the CDU is connected to the inlet of the air-liquid heat exchanger and the inlet of the liquid distribution unit, respectively. The outlet of the air-liquid heat exchanger is connected to the inlet of the liquid distribution unit, and the outlet of the liquid distribution unit is connected to the secondary side liquid return port of the CDU.

[0080] In this heat dissipation mode, a portion of the cooling medium is directly supplied to the liquid distribution unit by the CDU, while the other portion of the cooling medium is first supplied to the liquid distribution unit after passing through the air-liquid heat exchanger. The cooling medium is recycled. This heat dissipation mode can mix hot and cold cooling media, cooling down while circulating heat exchange. It is suitable for scenarios with medium power density.

[0081] As shown in Figure 7, in the third heat dissipation mode, the secondary side liquid outlet of the CDU is connected to the inlet of the air-liquid heat exchanger and the inlet of the liquid distribution unit, respectively, and the outlet of the air-liquid heat exchanger and the outlet of the liquid distribution unit are both connected to the secondary side liquid return port of the CDU.

[0082] In this cooling mode, the cooling medium provided by the CDU is divided into two: one supplying the air-cooled radiator and the other supplying the distribution unit. After heat exchange through the two separate channels, the cooled medium flows back to the CDU after the heat exchange is combined. This mode is suitable for scenarios with high power density.

[0083] Of course, the cabinet provided in this application embodiment may also integrate components such as switches, and this application embodiment does not limit this.

[0084] The structure of the prefabricated integrated air-liquid cabinet provided in the embodiments of this application will be described in general with reference to Figures 8 and 9 below.

[0085] As shown in Figure 8, a display screen 80 is installed on the front door of the cabinet, and the cabinet integrates a switch 81, a monitoring platform 82, a rack-mounted CDU 83, and multiple front door temperature sensors 84.

[0086] As shown in Figure 9, the rear door of the server rack uses a backplane fan door 85 (i.e., a backplane door with an air-liquid heat exchanger). The rack integrates a PDU, as well as a piping system connecting the CDU to the air-liquid heat exchanger and the liquid distribution unit. The backplane fan door has a large area of ​​heat dissipation coils. The cooling medium in the heat dissipation coils carries away the heat generated at the back of the server and exhausts the cooled air into the indoor environment. When the server fans are insufficient to dissipate heat, the fan on the backplane fan door assists in cooling and dissipates the heat accumulated at the rear door of the rack.

[0087] The bottom of the cabinet has a pre-fabricated drip tray with a water immersion sensor. Additionally, the cabinet back panel fan door has a pre-fabricated door status sensor, a temperature sensor inside the cabinet rear door, a cabinet pressure sensor, a fan air supply temperature sensor, and a bottom condensate sensor.

[0088] The prefabricated integrated air-liquid cooling cabinet provided in this application embodiment has a prefabricated power supply system, liquid cooling system, air-liquid heat exchanger, and piping system (the piping system formed by connecting the CDU with the liquid distribution unit and the air-liquid radiator). It can be prefabricated in one go and highly integrates core sub-components such as liquid cooling, power distribution, and monitoring. The degree of prefabrication is high. During on-site installation and configuration, only the power supply of the PDU and the primary side piping interface of the CDU and the liquid cooling piping connection of the liquid distribution unit to the cold plate liquid-cooled server need to be completed. The rest are prefabricated, which greatly reduces the on-site installation and configuration work.

[0089] Through multiple monitoring units and platforms, the system can monitor rack status parameters such as internal rack temperature, internal and external pressure difference, PDU power supply and distribution information, CDU outlet temperature, CDU return temperature, solenoid valve opening (first and second control valves), pipeline flow rate, pipeline temperature, fan speed, fan supply air temperature, and rack rear door temperature. These rack status parameters are displayed modularly on the HMI screen. Using pre-configured control algorithms, based on the rack status parameters, the system controls the flow rate and temperature of the cooling medium supplied by the CDU, the opening of the solenoid valves, the switching of cooling modes by the solenoid valves, and the fan speed, achieving optimal flow distribution in the cooling system and reducing energy consumption.

[0090] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
