Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquid cooling systems face issues with insufficient cooling liquid over time due to vaporization, leading to potential damage if not replenished, and existing solutions do not effectively manage hydraulic pressure during liquid supply.
Innovation Solution
A liquid supply mechanism with a plunger, damping member, and driving unit that automatically injects cooling liquid into the system when needed, using a chamber and axial hole configuration to adjust damping effect based on liquid levels, preventing high hydraulic pressure and ensuring efficient heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a liquid supply mechanism supplies cooling liquid to the liquid cooling system, then the cooling liquid level is maintained and heat dissipation efficiency is ensured, but high hydraulic pressure may be generated causing system damage
Solution Approach 1:
The plunger is designed to move dynamically within the chamber, adjusting its position based on liquid level changes. This dynamic movement allows the mechanism to supply liquid when needed while automatically reducing pressure buildup, resolving the contradiction between maintaining heat dissipation efficiency and preventing excessive hydraulic pressure
Solution Approach 2:
The mechanism changes the physical state parameters of the liquid supply process by using the plunger's positional changes to modulate flow rate and pressure. When the plunger moves to different positions in the chamber, it adjusts the supply parameters dynamically, ensuring adequate cooling liquid supply without generating damaging hydraulic pressure
2Device complexity
If the cooling liquid is not replenished after vaporization, then the system structure remains simple, but the liquid cooling system may be damaged due to insufficient cooling liquid
Solution Approach 1:
The liquid supply mechanism is designed to automatically detect and respond to cooling liquid level changes through the plunger's movement. The system self-regulates by having the plunger move in response to liquid level changes, automatically replenishing cooling liquid without requiring external intervention or complex control systems, thus maintaining simplicity while ensuring reliability
Solution Approach 2:
The mechanism incorporates a feedback loop where the plunger's position responds to liquid level changes in the chamber. This automatic feedback mechanism detects when cooling liquid needs replenishment and triggers the supply process, ensuring system safety without adding excessive complexity
