Flow-Path Controller Reconfiguration for Cooling Leak Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid-cooling systems for computer systems lack compatible leak detectors and flow-rate sensors, and do not provide controllable, reconfigurable, or customizable fluid flow paths, which are necessary for detecting leaks and adjusting fluid flow rates to prevent damage to electronic components.
Innovation Solution
The development of electro-mechanically actuated flow-path controllers with automatically decoupleable couplers and valves, which include sensors that emit simulated signals corresponding to observed operational parameters, allowing controllers to issue commands for actuator activation and fluid path reconfiguration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional liquid-cooling systems are used, then cooling function is provided, but leak detection and flow-rate monitoring are not compatible with existing systems
Solution Approach 1:
The patent uses simulated fan-tachometer signals as a copy of the actual operational parameters. Sensors detect real conditions (flow rate, leak presence) and generate simulated signals that mimic fan speed readings, allowing existing control systems to interpret cooling system status through a familiar signal format without requiring new detection protocols
Solution Approach 2:
The patent introduces simulated fan-tachometer signals as an intermediary between the cooling system sensors and existing control systems. This intermediary layer translates diverse sensor data (flow rate, leak detection) into a universal signal format that existing systems can process, enabling compatibility without modifying the original control architecture
2Productivity
If liquid-cooling systems operate without controllable flow paths, then system simplicity is maintained, but ability to respond to leaks and optimize cooling is reduced
Solution Approach 1:
The patent implements dynamically controllable flow paths using electro-mechanically actuated valves and decoupleable couplers. These components can change the fluid flow configuration in real-time based on detected conditions (leaks, flow rate variations), allowing the system to adapt its structure dynamically rather than being fixed, thereby enabling cooling optimization without permanent complexity
Solution Approach 2:
The system uses automated control where sensors detect conditions and trigger actuators to adjust flow paths without human intervention. The electro-mechanically actuated valves and decoupleable couplers automatically reconfigure the cooling system in response to detected leaks or suboptimal flow rates, enabling self-adjusting cooling optimization
3Extent of automation
If automated actuators are added for flow control, then response to leaks and flow changes is improved, but system complexity increases
Solution Approach 1:
The patent employs universal control signals (fan-tachometer signals) that can represent multiple different conditions (leak presence, flow rate, system status). This multi-functionality allows a single control infrastructure to handle diverse monitoring and control tasks, reducing the need for separate specialized systems and thereby limiting the increase in overall system complexity despite enhanced automation

AI summary
An observed operational state can include an operational state of one or more system devices. A sensor can emit, in response to a detected observable condition reflective of a given operational state, a simulated signal reflective of a different operational state as a proxy for the detected condition. A controller receiving such a proxy signal can, at least partially responsively to the proxy signal, issue a command corresponding to the given operational state. An electro-mechanical actuator can be selectively activatable responsive to the command.
