Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid cooling systems for servers face challenges in efficient fluid distribution, installation complexity, maintenance reliability, and power density limitations due to the use of manifolds and flexible hoses, which complicate installation and maintenance and restrict server loading capacity.
Innovation Solution
A fluid distribution system integrated into the server chassis, featuring connector plates that can be manually translated to engage with server boards, paired main connectors for connection to a rack manifold, and a locking mechanism to secure the chassis, enabling efficient fluid recirculation and simplified maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If flexible hoses are used to circulate liquid to servers, then installation flexibility is improved, but system reliability deteriorates due to loose hoses degrading the entire system
Solution Approach 1:
The patent integrates the fluid distribution system directly into the rack structure, merging previously separate components (manifold, hoses, connection points) into a unified integrated system. This eliminates loose hoses while maintaining installation flexibility through the integrated design that accommodates server loading from the front.
2Adaptability or versatility
If manifolds with flexible hoses are used for liquid cooling, then cooling coverage is improved, but device complexity increases due to numerous hoses requiring matching and maintenance
Solution Approach 1:
The patent extracts and eliminates the flexible hoses from the system, removing the complex matching and management requirements. The fluid distribution function is achieved through integrated connection points and channels built into the rack structure, simplifying the system while maintaining cooling coverage.
3Ease of manufacture
If flexible hoses are used to distribute coolant, then ease of installation is improved, but maintenance difficulty increases due to complex hose matching and access requirements
Solution Approach 1:
By merging the fluid distribution infrastructure into the rack itself, the patent creates a unified system where connection points are permanently integrated. This maintains installation ease through the modular rack design while dramatically improving maintenance accessibility, as all connections are readily accessible from the rear without complex hose routing.
4Ease of operation
If traditional hose-based cooling is used, then installation flexibility is improved, but power density limitations increase due to restricted cooling capacity
Solution Approach 1:
The patent implements a dedicated liquid cooling infrastructure with integrated fluid channels and connection points designed for high-capacity coolant flow. This hydraulic system provides the cooling capacity needed for high power density servers while maintaining installation flexibility through the rack's modular architecture.

AI summary
A fluid distribution system is incorporated into a server chassis. Connector plates have fluid connectors designed to connect with fluid cooling receptacles on server boards. A linkage system can be manually manipulated to translate the connector plates so as to engage the electronics boards and connect the fluid connectors to the receptacle. A pair of main connectors connect to the rack's fluid manifold to circulate cooling fluid to cool devices mounted onto the server boards. A locking mechanism can be included to mechanically lock the chassis to the rack to prevent accidental dismount of the chassis from the rack. Also, an anchor mechanism may be provided to apply counter force when engaging the connector plates with the server boards so as to prevent accidental dismount of the server board by the moving connector plate.
