Description

A liquid-cooled cabinet data center

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure is based on and claims the priority of Chinese patent application with application number 202311117709.5 and application date August 31, 2023. The entire content of this Chinese patent application is incorporated herein by reference into this disclosure. Technical Field

[0003] The present disclosure relates to the technical field of data centers, and in particular to a liquid-cooled cabinet-type data center. Background Art

[0004] Data centers are the foundation supporting the rapid development of the digital economy. The increase in computing power demand has made the heat dissipation problem of servers increasingly critical.

[0005] At present, air cooling is gradually failing to meet the heat dissipation needs of data centers, and liquid cooling research has begun to dominate. Cold plate liquid cooling is the main form of liquid cooling. This cooling method is to set up a primary water circulation waterway, a secondary water circulation waterway, and a heat exchange unit. The coolant in the secondary circulation waterway exchanges heat with the cooling water in the primary circulation waterway in the heat exchange unit. The coolant is then pumped to the server by a secondary circulation water pump installed in the secondary circulation waterway for heat exchange, ultimately achieving cooling and heat dissipation of the server. In the prior art, in cold plate liquid cooling data centers, there are two main installation methods for the secondary circulation water pump: one is to be configured outside the cabinet, and the other is to be configured inside the cabinet. When configured outside the cabinet, the overall space occupied by the equipment is increased. When configured outside the cabinet, when the secondary circulation water pump fails, the water supply waterway, the return waterway, and the circuit need to be removed separately before the secondary circulation water pump can be removed from the cabinet, which makes maintenance and installation difficult.

[0042] It should also be understood that, while the terms "first," "second," and the like are used in this disclosure to describe various types of information, such information should not be limited to these terms; these terms are merely used to distinguish information of the same type from one another. For example, "first" information could also be referred to as "second" information, and similarly, "second" information could also be referred to as "first information" without departing from the scope of this disclosure.

[0043] It should be noted that in different drawings, the same reference numerals denote the same or substantially the same components.

[0044] 1-6 of the present disclosure illustrate schematic diagrams of a liquid-cooled cabinet-type data center according to a preferred embodiment of the present disclosure. The liquid-cooled cabinet-type data center includes a cabinet 10 , a server 20 , a cooling assembly 30 , and a heat exchange assembly 40 .

[0045] The server 20 , the cooling assembly 30 , and the heat exchange assembly 40 are all disposed in the cabinet 10 , and the cooling assembly 30 is attached to the server 20 .

[0046] In addition, the heat exchange component 40 includes: a base 41, a heat exchange unit 42, a power module 43, a base interface 44 and a secondary side circulating water pump module 45; the heat exchange unit 42 and the power module 43 are arranged in the base 41, the base interface 44 is arranged on the outer peripheral wall of the base 41, the base interface 44 has a first electrical connector 441, a first coolant water supply connector 442 and a first coolant return connector 443, the first coolant water supply connector 442 is connected to a coolant supply pipe 46, the coolant supply pipe 46 passes through the The heat exchange unit 42, the first coolant return connector 443 is connected to a coolant return pipe 47, and the power module 43 is electrically connected to the first electrical connector 441; the secondary side circulating water pump module 45 is provided with a water pump interface 451, and the water pump interface 451 has a second electrical connector 451a, a second coolant supply connector 451b and a second coolant return connector 451c. The secondary side circulating water pump module 45 is detachably connected to the machine base 41 through the mating connection between the water pump interface 451 and the machine base interface 44.

[0047] When the water pump interface 451 is plugged into the base interface 44, the first electrical connector 441 is electrically connected to the second electrical connector 451a, the first coolant supply connector 442 is docked with the second coolant supply connector 451b, the first coolant return connector 443 is docked with the second coolant return connector 451c, and the cooling assembly 30, the coolant supply pipe 46, the secondary side circulating water pump module 45 and the coolant return pipe 47 are connected end to end in sequence to form a secondary side circulating water circuit.

[0048] The secondary side circulation process is as follows: the low-temperature coolant flowing out after being cooled by the heat exchange unit 42 enters the secondary side circulation water pump module 45 through the coolant supply pipe 46. Under the pumping action of the secondary side circulation water pump module 45, it is distributed to the cooling assembly 30 through the coolant supply pipe 46 to exchange heat with the heating elements in the server 20, thereby effectively dissipating the heat of the heating elements of the server 20. The high-temperature coolant after heat exchange flows back to the heat exchange unit 42 through the coolant return pipe 47 for heat exchange, and then becomes low-temperature coolant and flows out of the heat exchange unit 42 to form a cycle.

[0049] Based on the above technical solution, the liquid-cooled cabinet data center of the embodiment of the present invention is provided with a heat exchange component 40 equipped with a secondary side circulating water pump module 45, and the heat exchange component 40 is installed in the cabinet 10, which can effectively save space; and through the matching connection between the base interface 44 on the outer wall of the heat exchange component 40 and the water pump interface 451 on the secondary side circulating water pump module 45, the secondary side circulating water pump module 45 can be detachably installed. When the secondary side circulating water pump module 45 is plugged into the base 41, the circuit, liquid supply water path and return liquid water path of the secondary side circulating water pump module 45 can be connected simultaneously, which is convenient for installation. When the secondary side circulating water pump module 45 fails, the secondary side circulating water pump module 45 can be directly pulled out from the base 41 for easy maintenance.

[0050] Specifically, the cabinet 10 can be configured as a hollow frame structure or a box-type structure equipped with a cabinet door, which is not limited here. Taking the cabinet 10 with a box-type structure equipped with a cabinet door on the front as an example, the secondary side circulating water pump module 45 is arranged on the left or right side of the base 41. When the secondary side circulating water pump module 45 needs to be repaired, the cabinet door is opened first, and the side of the cabinet 10 is reached from the front to pull the secondary side circulating water pump module 45 from the base 41 and remove it from the cabinet 10. When the secondary side circulating water pump module 45 needs to be installed or replaced, the water pump interface 451 of the secondary side circulating water pump module 45 is aligned with the base interface 44 and plugged in.

[0051] In some embodiments of the liquid-cooled cabinet data center, as shown in Figures 2, 3, and 5, two machine base interfaces 44 are spaced apart on the same side wall of the machine base 41, and each machine base interface 44 is detachably connected to a secondary side circulating water pump module 45; at the same time, a first valve group 48 is provided on the coolant supply pipe 46, and a second valve group 49 is provided on the coolant return pipe 47. The first valve group 48 can control the conduction or cutoff between the first coolant supply connector of each machine base interface 44 and the coolant supply pipe 46, and the second valve group 49 can realize the connection or cutoff between the first coolant return connector of each machine base interface 44 and the coolant return pipe 47.

[0052] Of the two secondary-side circulating water pump modules 45, one is used for system operation and the other is in standby state. When the system is running, the water path of one of the secondary-side circulating water pump modules 45 is connected by controlling the first valve group 48 and the second valve group 49, while the water path connecting the other secondary-side circulating water pump module 45 is switched to a cut-off state and is not started as a standby. When a secondary-side circulating water pump module 45 fails, the working states of the first valve group 48 and the second valve group 49 are switched to connect the water path of the secondary-side circulating water pump module 45 that was originally in the standby state, thereby starting the standby secondary-side circulating water pump module 45 and cutting off the water path of the faulty secondary-side circulating water pump module 45, so that the faulty secondary-side circulating water pump module 45 can be removed for maintenance without affecting the continuous operation of the system.

[0053] According to actual needs, more than two secondary-side circulating water pump modules 45 may be provided, that is, at least two secondary-side circulating water pump modules 45 may be provided as backup.

[0054] Specifically, as shown in Figure 2, the coolant supply pipe 46 includes a liquid supply main pipe 461 and at least two liquid supply branch pipes 462. The liquid supply main pipe 461 passes through the heat exchange unit 42, and one end of each liquid supply branch pipe 462 is connected to the upstream end of the liquid supply main pipe 461, and the other end of each liquid supply branch pipe 462 is connected one-to-one to the first coolant water supply joint 442 of each machine base interface 44. The coolant return pipe 47 includes a liquid return main pipe 471 and at least two liquid return branch pipes 472. One end of each liquid return branch pipe 472 is connected to the downstream end of the liquid return main pipe 471, and the other end of each liquid return branch pipe 472 is connected one-to-one to the first coolant water return joint 443 of each machine base interface 44.

[0055] Based on this, referring again to Figure 2, in some embodiments, the first valve group 48 includes a plurality of first valves 481 connected one-to-one to each liquid supply branch 462, and the second valve group 49 includes a plurality of second valves 491 connected one-to-one to each liquid return branch 472, and the first valve 481 and the second control valve 491 are both two-way valves; in actual operation, the first valve 481 on the liquid supply branch 462 connected to the secondary side circulating water pump module 45 that needs to be started and the second valve 491 on the liquid return branch 472 connected thereto are switched to the on state, so that the water path of the secondary side circulating water pump module 45 can be opened, and the remaining first valves 481 and second valves 491 are all switched to the off state.

[0056] As an alternative embodiment, the first valve group 48 can also be a multi-way valve arranged at the connection fulcrum of each liquid supply branch pipe 462 and the liquid supply main pipe 461, and the second valve group 49 can be a multi-way valve arranged at the connection fulcrum of each return liquid branch pipe 472 and the return liquid main pipe 471. By replacing the above-mentioned two-way valve with a multi-way valve, the switching of the conduction state of each flow path can also be achieved.

[0057] The liquid-cooled cabinet data center of some embodiments also includes a control system (not specifically shown in the drawings), which is electrically connected to the power module 43, the secondary side circulating water pump module 45, the first valve group 48 and the second valve group 49, respectively. The control system is configured to: switch the working status of the first valve group 48 and the second valve group 49 according to actual needs, thereby controlling the water circuit conduction or cutoff of each secondary side circulating water pump module 45, and finally controlling the start and stop of each secondary side circulating water pump module 45.

[0058] Preferably, in some embodiments, as shown in FIG3 , a power cord 410 is connected between the power module 43 and the first electrical connector 441, and the first electrical connector 441 is slidably connected to the base 41. When the secondary-side circulating water pump is plugged into the base 41, the first electrical connector 441 cooperates with the second electrical connector 451a to be plugged in, and at least part of the power cord 410 is idle in the cabinet 10, that is, at least part of the power cord 410 is not in a tensioned state; when one of the secondary-side circulating water pump modules 45 fails, in the process of removing the failed secondary-side circulating water pump module 45, it is necessary to first pull the secondary-side circulating water pump outward from the base 41. At this time, due to the first electrical connector 44 1 and the second electrical connector 451a, the first electrical connector 441 will move outward with the faulty secondary side circulating water pump module 45 relative to the base 41, so that the secondary side circulating water pump module 45 is still in a powered state after being pulled out a certain distance; when performing fault maintenance, the faulty secondary side circulating water pump module 45 must first be pulled out of the base 41 and taken out of the cabinet 10 for simple online maintenance. During this process, the secondary side circulating water pump module 45 must remain powered. Only when damage is found during the online maintenance process, the first electrical connector 441 and the second electrical connector 451a are manually disconnected to send the faulty secondary side circulating water pump out for maintenance.

[0059] Specifically, as shown in Figure 3, a winder 420 is rotatably installed in the base 41, and an elastic reset member (not specifically shown in the drawings) is connected between the winder 420 and the base 41, and the structure is similar to a commonly used tape measure; when the secondary side circulating water pump module 45 is installed on the base 41, the power cord 410 is at least partially wound around the winder 420, and when the secondary side circulating water pump module 45 is pulled outward, as the first electrical connector 441 moves outward, the part of the power cord 410 wound on the winder 420 is pulled out; after the first electrical connector 441 is pulled out, the connection between the first electrical connector 441 and the second electrical connector 451a is manually disconnected, and under the action of the elastic reset member, the winder 420 can automatically reset to wind the power cord 410, thereby pulling the first electrical connector 441 to automatically reset to the base 41.

[0060] Exemplarily, the first electrical connector 441 and the second electrical connector 451a are respectively a male connector and a female connector that are mated together. A slide groove and a wire hole (not specifically shown in the accompanying drawings) that are connected from the outside to the inside are provided on the side wall of the base 41. Under the pre-stretching action of the elastic reset member, the first electrical connector 441 is movably placed in the slide groove, and the slide groove can limit the first electrical connector 441 from entering the interior of the base 41. The power cord 410 passes through the wire hole and is connected to the first electrical connector 441; when the first electrical connector 441 is pulled out a certain distance, after the first electrical connector 441 and the second electrical connector 451a are manually disconnected, the first electrical connector 441 can be automatically stored in the slide groove under the automatic reset action of the winder 420.

[0061] As an alternative, the first electrical connector 441 and the second electrical connector 451a may be connected in another manner, such as by a snap connection, etc., which is not limited here.

[0062] Exemplarily, as shown in FIG3 , the winder 420 is disposed in the power module 43 , which can prevent the power cord 410 from being interfered with by other components in the base 41 during the winding and unwinding process.

[0063] In some embodiments, referring to FIG2 , the liquid-cooled cabinet data center further includes a primary-side water supply pipeline 430 and a primary-side circulating water pump 50 . The primary-side water supply pipeline 430 passes through the heat exchange unit 42 . The primary-side circulating water pump 50 is connected to the primary-side water supply pipeline 430 and is disposed outside the cabinet 10 . The primary-side cooling water is used to perform heat exchange on the secondary-side cooling liquid flowing through the heat exchange unit 42 , so as to achieve circulating cooling of the server 20 by the secondary-side cooling liquid.

[0064] When the system is working, the primary side circulation process is as follows: the primary side circulating water flows out from the cold source (not specifically shown in the drawings), enters the heat exchange unit 42 through the primary side water supply pipe 430, exchanges heat with the coolant in the secondary side circulating water circuit here, and then flows out of the heat exchange unit 42, and returns to the cold source under the pumping action of the primary side circulating water pump 50, forming a cycle.

[0065] In some preferred embodiments, as shown in FIG1 , the heat exchange assembly 40 is disposed at the bottom of the cabinet 10, and the server 20 is disposed above the heat exchange assembly 40. Typically, a plurality of partitions are provided in the cabinet 10, which are spaced apart in an upper and lower manner. The server 20 and the heat exchange assembly 40 are respectively disposed on each partition so as to be stacked up and down for easy assembly.

[0066] Furthermore, in order to facilitate the rational use of the space of the cabinet 10, the overall shape of the cabinet 10 is set to a cube, and correspondingly, the outer peripheral contour of the base 41 and the outer peripheral contour of the secondary side circulating water pump module 45 are both set to a cube. When the secondary side circulating water pump module 45 is installed on the base 41, the side wall of the secondary side circulating water pump module 45 fits in with the outer peripheral wall of the base 41, and the assembled base 41 and the secondary side circulating water pump module 45 are cube-shaped as a whole.

[0067] Preferably, the base interface 44 is configured to protrude from the outer wall of the base 41, and the water pump interface 451 is concave relative to the outer peripheral wall of the secondary side circulating water pump module 45. When the secondary side circulating water pump module 45 is plugged into the base 41, the base interface 44 is matched and accommodated in the water pump interface 451.

[0068] As an alternative, the base interface 44 may be configured to be concave, while the water pump interface 451 may be configured to be convex to match.

[0069] In addition, multiple heating elements in the server 20 usually need to be cooled and multiple servers 20 need to be arranged in a cabinet 10; in order to be able to dissipate heat for each heating element, as shown in Figure 4, the cooling assembly 30 in some embodiments includes multiple cooling plates 31 respectively attached to different heating elements of each server 20, and the secondary side circulation water circuit also includes a first manifold 60 and a second manifold 70, and the first manifold 60 and the second manifold 70 are both arranged in the cabinet 10; a cooling channel is provided in the cooling plate 31, and the two ends of the cooling channel are respectively a water inlet and a water outlet, and the first manifold 60 has a water inlet end and multiple water outlet ends The water inlet end of the first sub-manifold 60 is connected to the downstream end of the coolant supply pipe 46, and the multiple water outlet ends of the first sub-manifold 60 are connected one-to-one to the water inlet of each cold conduction plate 31. The second sub-manifold 70 has multiple water inlets and one water outlet end. The multiple water inlets of the second sub-manifold 70 are connected one-to-one to the water outlet of each cold conduction plate 31, and the water outlet end of the second sub-manifold 70 is connected to the upstream end of the coolant return pipe 47; the low-temperature coolant flows out of the heat exchange unit 42 and is distributed to each cold conduction plate 31 through the first sub-manifold 60. After heat exchange in the cold conduction plate 31, it is collected by the second sub-manifold 70 and flows into the coolant return pipe 47.

[0070] Exemplarily, the first sub-manifold 60 and the second sub-manifold 70 are both arranged on the back of the cabinet 10, and the multiple water outlets of the first sub-manifold 60 and the multiple water inlets of the second sub-manifold 70 are arranged at intervals in the vertical direction to facilitate the connection of the water path.
