Buoyancy Tray Structure for Immersion Server Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current server maintenance in large-scale liquid-cooling cabinets requires mechanical lifting arms due to server weight, leading to low operating efficiency, skill dependency, and safety risks, violating rapid operation principles.
Innovation Solution
A buoyancy tray with a buoyancy component and slide tracks allows servers to be pulled out using handles, eliminating the need for mechanical lifting arms, and enabling direct server handling without special training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a mechanical lifting arm is used to lift and transfer the server, then the server can be pulled out from the cabinet, but the operating time is long and operating efficiency is low
Solution Approach 1:
The patent applies the anti-weight principle by introducing a buoyancy tray with buoyancy components that generate upward buoyant force to counterbalance the downward gravitational force on the server. This allows operators to easily lift and remove servers from the cabinet without requiring mechanical lifting arms, directly resolving the contradiction between operating efficiency and time consumption.
2Ease of operation
If a mechanical lifting arm is used to lift and transfer the server, then the server can be pulled out from the cabinet, but skill acquisition costs are increased
Solution Approach 1:
The buoyancy tray enables self-service operation where the tray automatically generates buoyant force to support the server weight. Operators simply need to pull the server out using handles, without requiring complex mechanical lifting arm operations or specialized training, thus improving ease of operation while reducing device complexity.
3Loss of substance
If servers are directly inserted into the cabinet fully filled with coolant, then cooling is achieved, but coolant waste occurs when servers are removed
Solution Approach 1:
The buoyancy tray acts as an intermediary device between the server and the coolant. When the server is removed, the tray remains in the cabinet and can be easily filled with coolant again, avoiding the need to drain and refill the entire cabinet. This significantly reduces coolant waste while maintaining ease of server removal operations.

AI summary
A buoyancy tray, a server, and a server cluster are provided by the present application. In the present application, the buoyancy component is disposed on the tray body, when the tray body is located in the immersion coolant of the cabinet, buoyancy generated by the buoyancy component may assist maintenance personnel in pulling out the server from the cabinet directly through the handles on the tray body, thereby facilitating convenient and labor-saving operation, and improving the operating efficiency.
