Description
- Embodiments of the present disclosure relate generally to airflow management in a data center. More particularly, embodiments of the disclosure relate to cooling systems and methods of designing and configuring cooling systems for a data center.
- With the booming of AI applications, high performance computing, cloud computing and data-driven applications, data centers as well as the compute and storage infrastructures have becoming increasingly critical for a company to maintain its competitive edges. Maintaining a data center is expensive and part of the expenses is related to cooling the data center.
- A data center may keep growing in size, and serving and maintaining cooling systems in the data center may become expensive. In some data centers, all the cooling hardware units are integrated as an inseparable unit. If a particular component becomes defective, the whole cooling system may need to be replaced or redesigned, which greatly increases the service and maintenance cost of the data center. In addition, as more efficient cooling hardware becomes available, it would be hard to plug in the new hardware into the existing cooling system. Therefore, designing a cooling solution and an IT enclosure in a combined manner may benefit the modern IT cluster and hardware.
- Embodiments of the invention are illustrated by way of example and not limitation in the figures of the accompanying drawings in which like references indicate similar elements.

FIG. 7 illustrates a process of creating a cooling a cooling system for a data center. - Various embodiments and aspects of the inventions will be described with reference to details discussed below, and the accompanying drawings will illustrate the various embodiments. The following description and drawings are illustrative of the invention and are not to be construed as limiting the invention. Numerous specific details are described to provide a thorough understanding of various embodiments of the present invention. However, in certain instances, well-known or conventional details are not described in order to provide a concise discussion of embodiments of the present inventions.
- Reference in the specification to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in conjunction with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase “in one embodiment” in various places in the specification do not necessarily all refer to the same embodiment.
- According to various embodiments, described herein are systems and methods for designing and configuring cooling systems for server racks in an IT cluster or a data center. In one embodiment, a cooling system can include a connection module with standard fluid connections and standard fluid ports, and a number of cooling modules, such as a heat exchanger module, a pump module, and a first bypass module, and a second bypass module. The connection module can use the standard fluid connections and standard ports to connect the cooling modules together as a single cooling unit, also can be understood as a complete cooling module. The cooling unit can be attached to an IT enclosure, which can be an IT rack with cooling hardware/system
- In one embodiment, the fluid connections can connect the IT enclosure to the connection module, and connect multiple pairs of the cooling modules. The fluid connections are assembled within the connection module. For example, a fluid connections can connect the first bypass module and the second bypass module, and another fluid connection can connect the heat exchanger and the pump module. These two fluid connections are further connected by a two-way loop in the connection module in one embodiment.
- In one embodiment, a pair of fluid ports can be attached to either side of the IT enclosure. Since the IT enclosure is bidirectional and allows the cooling fluid to pass the IT enclosure from either side, either of the pair of fluid ports can be used as an inlet fluid port or an outlet fluid port. The inlet fluid port and the outlet fluid port on the IT enclosure are connected by either an internal fluid connection or other fluid management solutions within the IT enclosure. To enable the fluid flow from the outlet fluid port on the IT enclosure into the second bypass module, part of fluid connection can be in an extension fluid connection that connects the IT enclosure outlet fluid port to the second bypass module inlet fluid port and enables the cooling fluid.
- In one embodiment, a fluid port can also be attached to the first bypass module, and functions as an outlet fluid port for the cooling system. The cooling fluid can enter the cooling system via the inlet fluid port on the IT enclosure, and can exit the cooling system via the outlet fluid port.
- In one embodiment, the connection module and the cooling modules can be assembled together to form a cooling unit. Although the IT enclosure is a bidirectional, which means that the two fluid ports on the IT enclosure can be both used as either inlet or outlet, the cooling unit is unidirectional, which means that the cooling fluid can pass the connection module and the plurality of cooling modules in the cooling unit only from one direction. Therefore, the outlet fluid port on the first bypass module in the cooling unit can only be used an outlet fluid port, and cannot be used as an inlet fluid port, since fluid flowing direction is controlled by the pump. In another embodiment, if the pump in the module is changed and its fluid pumping direction is changed, the fluid port on the second bypass loop is used as the outlet port and the fluid port on the first bypass loop is used as the inlet port only.
- In one embodiment, the connection module can be customized based on design requirements of the cooling system and features of the cooling modules. Features of the IT enclosure is also considered in the design of the cooling system. The cooling modules can be independently serviced and replaced during normal operation of the cooling system. If any of the cooling modules become defective or malfunction, the two bypass loops will be used to create a complete loop for the cooling fluid without the participation of the defective cooling module, thereby ensuring that the defective cooling module can be replaced with minimal impact on the normal operation of the cooling system.
- The connection module can be customized for different cooling systems by connecting the modules with cooling modules through standard ports, and the fluid connections within the connection module are for connecting the modules into a complete system.
- The various embodiment described above enable different types of cooling hardware to be integrated into a cooling system, and also enable easy servicing and maintaining of the existing cooling hardware in the system. Any of the cooling hardware (e.g., cooling modules) can be replaced by plugging a replacement cooling module into the cooling system via standard fluid ports. Using the above-described features, a variety of cooling systems can be designed, configured, and created, including liquid cooling systems, immersion cooling systems, and hybrid cooling systems.
- Additional advantages of such systems include more efficient rack architectures for deploying cooling systems with different types of cooling configurations; modular designs for providing flexibility in service and maintenance; elimination of system or facility loop complexity; and decoupling cooling system designs from facility loop designs.
- Another advantage of such cooling systems is that the different standard cooling modules can be plugged into the connection module to form different cooling systems to have different functionalities, which increase the system modularity.
- Further advantages of such cooling systems include compatibility with different IT or server configurations, since thermal management and heat transfer capability are configured individually; fast adaptation to variations in deployment requirement; and high reliability.
