Description

Hot-swappable pump units and their suitable coolant distribution units

This case relates to a pump unit, specifically a hot swappable pump unit (HSPU), which is detachably installed in a coolant distribution unit (CDU) and used as a cooling device for data center servers. Used to simplify the servicing procedures of hot-swappable pump units. This allows users to perform maintenance on hot-swappable pump units without shutting down the data center servers.

A data center has a structure that houses computer systems and related components such as telecommunications and storage systems. A closed accommodation space is formed inside the casing of the data center to accommodate multiple heating devices. In order to perform cooling, a coolant needs to be delivered to the heat sink attached to the heating device through a coolant distribution unit (CDU) including a pipeline assembly and a pump. In this way, the purpose of heat dissipation and cooling of various heat-generating devices can be achieved.

However, since many devices are accommodated in the data center casing structure, when the pump body disposed in the data center casing structure and combined with the coolant distribution unit needs to be maintained or replaced, the data center and the coolant must first be shut down. Distribute the entire system of the unit and drain the coolant from the coolant distribution unit before removing the equipment or pump body for repairs. Therefore, maintenance procedures for the pump body in conventional coolant distribution units are inconvenient. Especially in data center applications, coolant distribution units and processing Data servers are combined. When repairing or replacing the pump body of the coolant distribution unit, if the server needs to be shut down to perform the operation, the normal data processing process of the server will be affected, thereby causing heavy losses.

On the other hand, the pump structure and corresponding pipeline components used in traditional coolant distribution units are very complex. In addition, the maintenance procedure of the pump body is further limited by the combination of the pump body and the pipeline, so the operating performance and quality of the maintenance procedure of the pump body in the coolant distribution unit cannot be improved.

In view of this, there is a need to provide a hot-swappable pump unit that is detachably disposed in a coolant distribution unit and used for cooling data center servers to simplify the maintenance procedures of the hot-swappable pump unit. This allows users to perform maintenance on hot-swappable pump units without shutting down data center servers or draining coolant.

The purpose of this case is to provide a hot-swappable pump unit that is detachably installed in a coolant distribution unit and used for cooling data center servers, thereby simplifying the maintenance procedures of the hot-swappable pump unit.

On the other hand, the electrical connection between the pump body and the coolant distribution unit in the hot-swappable pump unit can also be combined with the locking operation in the docking direction. The connector of the hot-swappable pump unit is arranged facing the docking direction, and is placed on the third side of the fastener. When the first engaging part and the second engaging part of the locking assembly engage with each other, the hot-swappable pump unit is driven to be connected to the water distribution circuit through the quick connector, and at the same time, the connector is connected to the corresponding connection socket on the coolant distribution unit to complete the electrical connection. . With this, the user can complete the pipeline connection and electrical connection of the hot-swappable pump unit and the coolant distribution unit at the same time by operating the locking assembly and the fastener, further simplifying the maintenance of the hot-swappable pump unit. program.

When the hot-swappable pump unit 2 is connected to the water distribution circuit 10, the coolant in the water distribution circuit 10 can be driven to circulate to cool the servers in the data center. In this embodiment, the hot-swappable pump unit Unit 2 includes a housing 20 , a pump body 21 , a pump inlet piece 22 , a pump outlet piece 23 and a locking assembly 24 . The housing 20 has an accommodation space 200 and a first side wall 201 and a second side wall 202 opposite to each other in the X-axis direction.
