Liquid Cooling Manifold Alignment for Blind Rack Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid cooling systems in Information Handling Systems (IHSs) face challenges in precisely aligning liquid cooling manifolds with racks, leading to potential misalignment of couplings and hindered blind coupling of servers to the cooling system.
Innovation Solution
The use of alignment trays and brackets to precisely position liquid cooling manifolds within the rack, allowing for blind coupling of servers to the cooling system by ensuring accurate alignment before fastening the brackets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If liquid cooling manifolds are installed without alignment trays, then the installation process is simpler, but the coupling alignment between manifolds and servers becomes imprecise
Solution Approach 1:
Alignment trays are introduced as intermediary components between the liquid cooling manifolds and the rack structure. These trays provide precise positioning features that guide manifold installation and ensure accurate coupling alignment with server components, eliminating the need for complex manual alignment procedures while maintaining installation simplicity.
Solution Approach 2:
The alignment trays are pre-installed in the rack before manifold installation. These trays contain pre-positioned alignment features and coupling interfaces that prepare the installation environment in advance, allowing manifolds to be quickly positioned and secured with precise alignment without requiring complex adjustment procedures during the installation process.
2Productivity
If manual visual alignment is used for coupling manifolds, then alignment accuracy can be achieved, but the installation time increases and requires skilled operators
Solution Approach 1:
The alignment trays incorporate self-aligning features such as tapered guides, keyed interfaces, and positioning pins that automatically guide the manifold into correct alignment during installation. This self-service alignment mechanism eliminates the need for manual visual measurement and adjustment, enabling quick installation by operators of any skill level while ensuring consistent coupling alignment accuracy.
3Ease of operation
If alignment trays are used to precisely position manifolds, then coupling alignment is improved, but the number of components and assembly steps increases
Solution Approach 1:
The alignment tray design merges multiple functions into a single component: it provides structural support for the manifold, incorporates alignment positioning features, and integrates coupling interfaces for both the manifold and server. This consolidation eliminates the need for separate alignment fixtures, positioning devices, and coupling mechanisms, reducing the total number of components while enabling blind coupling capability where servers can be installed without visual verification of coupling alignment.

AI summary
Methods and systems are provided for aligning liquid cooling manifolds of a computing rack, where the alignment allows IHSs (Information Handling Systems, such as rack-mounted servers) to be blindly coupled to these manifolds when inserted into a slot of the rack. A first alignment tray is inserted in slot of the rack until alignment couplings of the tray are coupled to the liquid cooling manifold of the rack. A second alignment tray is inserted in another slot of the rack until alignment couplings of the second tray are coupled to the liquid cooling manifold. The liquid cooling manifold is fastened to the rack while the liquid cooling manifold is coupled to the trays. The trays are removed and an IHS is inserted into a slot of the rack until coupled to the liquid cooling manifold, where couplings of the IHS are aligned with couplings of the liquid cooling manifold.
