Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The leakage of Coolant Distribution Units (CDU) or Reservoir and Pump Units (RPU) in liquid cooling systems poses a significant risk of damaging electronic components due to increased power density in high-power computing applications like cloud and edge computing, where traditional liquid cooling solutions lack effective leakage detection and containment.
Innovation Solution
A liquid cooling device comprising a cabinet, a liquid flowing unit, a liquid tray with a confluence groove, and a liquid sensor that detects coolant leakage by contacting the coolant in the groove, allowing for timely warning and containment, thereby reducing the risk of electronic component damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If liquid cooling is implemented for high-power computing, then cooling effectiveness is improved, but the risk of coolant leakage damaging electronic components increases
Solution Approach 1:
The liquid tray is pre-installed in the cabinet below the liquid flowing unit to create a containment structure before leakage occurs. The confluence groove is pre-formed to guide leaked coolant away from electronic components, preventing direct contact between coolant and sensitive electronics.
Solution Approach 2:
The liquid tray acts as an intermediary containment structure between the liquid flowing unit and the electronic components. It intercepts leaked coolant and redirects it through the confluence groove to a safe drainage location, isolating the harmful coolant from vulnerable electronics.
2Power
If traditional liquid cooling solutions are used, then cooling capability is provided, but leakage detection and containment capability is insufficient
Solution Approach 1:
The liquid sensor is installed in the confluence groove to provide real-time feedback on coolant leakage. When the sensor detects coolant presence, it triggers an alarm signal, enabling immediate response to leakage events and preventing further damage to electronic components.
Solution Approach 2:
The confluence groove automatically guides leaked coolant to a collection point without external intervention. The groove's geometry self-directed the flow of coolant away from sensitive areas, providing passive containment that operates independently of active control systems.

Function Achieved in This Case
The solution effectively detects and contains coolant leakage, reducing the risk of damage to electronic components and enhancing the reliability of liquid cooling systems in high-power computing environments by utilizing a sensor-activated system that alerts and prevents coolant from reaching sensitive areas.
Implementation Method 1
The liquid sensor 4 is placed in the confluence groove 31. The liquid sensor 4 can send a signal when the liquid sensor 4 senses the coolant, and the liquid sensor 4 senses the coolant by contacting the coolant.

AI summary
A liquid cooling device comprises a cabinet, a liquid flowing unit, a liquid tray, and a liquid sensor. The cabinet is configured for containing an electronic component. The liquid flowing unit comprises a plurality of liquid delivery pieces connected and configured for circulating coolant to cool the electronic component. The liquid tray defines a confluence groove configured for gathering the coolant leaking from two connected ones of the plurality of liquid delivery pieces. The liquid sensor is placed in the confluence groove and is configured for sending a signal when contacting with the coolant. When the coolant leaks from two connected ones of the plurality of liquid delivery pieces then drops on the liquid tray and flows into the confluence groove by gravity, the liquid sensor contacts with the coolant in the confluence groove and sends the signal. A server with the liquid cooling device is also disclosed.
