Immersion Cooling Bladder Modulates Liquid Level
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional immersion cooling systems face inefficiencies in managing the volume of immersion cooling liquid, which is costly and requires different volumes for various electronic components, and lack the ability to quickly modulate the liquid level, especially during transportation or when access to components is needed.
Innovation Solution
A bladder system configurable between expanded and contracted states, integrated with a controller, allows for modulation of the immersion cooling liquid level within the immersion case, reducing the volume of liquid required and enabling efficient cooling while minimizing liquid loss during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large volume of immersion cooling liquid is used to fill the immersion case to a predetermined level, then adequate cooling of the electronic component is achieved, but the cost increases due to the expensive immersion cooling liquid
Solution Approach 1:
The patent changes the parameter of immersion cooling liquid volume from a fixed predetermined level to a dynamically adjustable level. The bladder device enables the volume to be varied based on the specific cooling requirements of different electronic components, allowing optimization between cooling effectiveness and liquid consumption cost.
Solution Approach 2:
The patent introduces a dynamic adjustment mechanism (bladder device) that allows the immersion cooling liquid volume to be modified on-demand. This transforms the static fixed-volume system into a dynamic system where the liquid level can be increased or decreased according to the thermal requirements of the electronic component being cooled.
2Reliability
If the immersion case is sealed to prevent liquid loss, then liquid spillage is prevented during transportation, but access to the electronic component becomes difficult without draining the liquid
Solution Approach 1:
The patent applies dynamic adjustment of the immersion cooling liquid level using the bladder device. When component access is required, the bladder can be deflated to lower the liquid level, allowing easy access while maintaining the sealed containment structure. This eliminates the need to drain the entire liquid volume for maintenance operations.
Solution Approach 2:
The system performs preliminary action by adjusting the liquid level in advance before maintenance operations. The bladder can be pre-deflated to prepare the system for component access, or pre-inflated to ensure adequate cooling before operation begins.
3Ease of operation
If the immersion case is not sealed, then access to the electronic component is easier, but liquid spillage occurs during transportation
Solution Approach 1:
The patent uses the dynamic bladder device to adjust liquid level in response to operational requirements. During transportation, the bladder can be deflated to create space and prevent spillage. During maintenance, the liquid level can be lowered to facilitate access, all while maintaining a sealed containment structure that prevents unauthorized access and contamination.
4Adaptability or versatility
If different volumes of immersion cooling liquid are used for different electronic components, then cooling requirements are optimized, but system complexity increases
Solution Approach 1:
The patent implements a universal bladder device that can serve multiple electronic components with different cooling requirements using a single adjustable mechanism. Rather than requiring separate cooling systems for each component type, the single bladder-based volume control system can be adjusted to accommodate various component sizes and thermal needs, reducing overall system complexity.
