Liquid Cooling Flow-Path Control for Leak Isolation
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 offer controllable, reconfigurable, or customizable fluid flow paths, which are necessary for preventing damage to electronic components due to leaks or flow rate excursions.
Innovation Solution
Incorporation of sensors that emit simulated signals corresponding to observed operational parameters, such as leak presence or flow rate, and electro-mechanical actuators that respond to these signals to control fluid flow paths, including decoupling couplers and valves, compatible with existing communication protocols.

Engineering Contradiction Analysis
1Temperature
If liquid-cooling systems are used for computer systems, then cooling effectiveness is improved, but compatibility with existing leak detectors and flow-rate sensors is lost
Solution Approach 1:
The patent creates simulated fan-tachometer signals that replicate the electrical signal patterns produced by actual fan operation. These simulated signals copy the temporal and frequency characteristics of genuine fan tachometer outputs, allowing existing fan-monitoring circuitry to detect leak conditions without requiring specialized liquid-cooling sensors.
Solution Approach 2:
The system enables a single electrical signal interface to serve multiple functions: normal fan speed monitoring and leak detection. By encoding leak information within the fan-tachometer signal format, the system makes existing fan control circuits universally applicable to both cooling monitoring and leak detection in liquid-cooling systems.
2Reliability
If automated leak detection is implemented, then system reliability is improved, but device complexity increases
Solution Approach 1:
The leak detection system utilizes existing fan tachometer signal infrastructure to perform leak detection without requiring separate dedicated sensors or complex monitoring circuits. The system serves itself by repurposing available electrical signals for dual purposes, thereby achieving automated leak detection while minimizing additional hardware complexity.
3Object-affected harmful factors
If flow path control is added to liquid-cooling systems, then protection of electronic components is improved, but device complexity increases
Solution Approach 1:
The system incorporates flow path control capabilities that can preemptively isolate affected areas upon detecting leak conditions. By having control mechanisms pre-positioned and ready to activate, the system can quickly respond to leaks before they cause damage to electronic components, rather than requiring complex real-time analysis and response systems.

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.
