Server Movable Panel Locking Mechanism for Liquid Cooling Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data center cooling systems are prone to damage due to improper handling of servers, where manual connectors can be damaged when servers are removed without disconnecting from the liquid cooling assembly, leading to potential damage to the server, hose, and electronic rack.
Innovation Solution
A server and electronic rack design featuring a movable panel and locking member that allows for secure engagement and disengagement, preventing accidental detachment and ensuring safe removal of servers from the rack, with elastic units for automatic locking and hose channels for secure connector passage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual connectors are used to couple the liquid cooling assembly to the liquid manifold, then the server can be easily connected and disconnected, but the connectors and hoses may be damaged due to maloperation
Solution Approach 1:
The locking member is pre-configured to automatically engage with the locking panel when the server is inserted into the electronic rack. This preliminary locking action occurs before any potential maloperation can damage the connectors, ensuring that the connectors remain protected during normal operation while still allowing easy connection when properly operated.
Solution Approach 2:
The locking member acts as an intermediary mechanism between the server and the electronic rack. It provides a mechanical interface that prevents direct manual manipulation of the connectors and hoses, thereby protecting them from damage while still enabling easy server replacement through the proper use of the locking mechanism.
2Stability of the object's composition
If the server is securely locked to the electronic rack, then the server stability is improved, but the server cannot be removed without disconnecting the connectors
Solution Approach 1:
The locking mechanism is designed to be dynamic rather than permanent. The locking member can be engaged to provide stable locking during operation, but can also be disengaged to allow server removal. This dynamic behavior resolves the contradiction by providing both stability when needed and ease of removal when properly operated.
Solution Approach 2:
The locking function is segmented from the connector function. The locking member handles the mechanical securing of the server to the rack, while the connectors handle the fluid coupling. This segmentation allows the server to be securely locked in place during operation but still be removable when the locking member is disengaged, provided the connectors are properly disconnected first.
3Reliability
If a locking mechanism is added to prevent maloperation, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The locking mechanism is merged with the existing server and electronic rack structures. The locking member is integrated into the server chassis, and the locking panel is integrated into the electronic rack, rather than being separate add-on components. This merging approach provides the reliability benefits of a locking mechanism while minimizing the increase in overall device complexity.
Solution Approach 2:
The locking mechanism is designed to be self-actuating through the insertion and removal motions of the server itself. When the server is inserted into the electronic rack, the locking member automatically engages with the locking panel. When the server is removed, the locking member automatically disengages. This self-service design provides operational safety without requiring additional actuators, motors, or complex control systems.

AI summary
A server includes a chassis; a base panel fixedly coupled to the chassis; a movable panel coupled to the base panel; and a locking member fixedly coupled to the movable panel. The movable panel is movable relative to the base panel in a moving direction between an unlocked position where the locking member is configured to be disengaged with a locking panel of an electronic rack, and a locked position where the locking member is configured to be engaged with the locking panel of the electronic rack.
