Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The immersion cooling system for expansion cards faces challenges with space efficiency, as the motherboards with expansion cards occupy a significant amount of space, making it difficult to replace the expansion cards in the narrow system.
Innovation Solution
The electronic device incorporates a cage assembly with a fixed frame and movable frames, allowing the motherboard with expansion cards to be mounted on the movable frames, which can be integrated with the cage assembly, reducing space occupation and enabling easier replacement of expansion cards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the motherboard with expansion cards is fixed in the immersion cooling system, then the structure is stable, but the expansion cards are difficult to replace due to narrow space
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed mounting structure into a movable one. The motherboard is mounted on a movable frame that can slide along guide rails within the cage assembly, allowing the motherboard and expansion cards to be easily accessed and replaced by moving the entire assembly, thereby resolving the contradiction between structural stability and ease of replacement.
Solution Approach 2:
The patent segments the mounting structure into a fixed frame and a movable frame. The fixed frame provides structural stability and support, while the movable frame carries the motherboard and can be independently moved for maintenance purposes. This segmentation allows the system to simultaneously achieve stability and ease of operation.
2Productivity
If multiple expansion cards are mounted on the motherboard, then the computing capability is enhanced, but the overall size and space occupation are increased
Solution Approach 1:
The patent merges multiple expansion cards onto a single motherboard, which is then mounted on a movable frame within a compact cage assembly. This combining approach allows multiple high-capacity cards to be installed in a space-efficient manner, enhancing computing capability without proportionally increasing the overall volume occupied in the immersion cooling system.
Solution Approach 2:
The patent optimizes the spatial arrangement by utilizing vertical space and three-dimensional positioning within the cage assembly. The movable frame design allows the motherboard with multiple expansion cards to be positioned efficiently, maximizing the use of available space in the immersion cooling system while maintaining high computing capability.
3Temperature
If the motherboard is immersed in coolant for cooling, then the heat dissipation is improved, but the access and replacement of expansion cards become difficult
Solution Approach 1:
The patent applies dynamics by designing a movable frame that can be easily extracted from the immersion cooling system. The motherboard remains immersed in the coolant for effective heat dissipation during operation, but the movable frame can be quickly removed when maintenance is needed, providing excellent accessibility to the expansion cards without compromising cooling performance.
Solution Approach 2:
The movable frame acts as an intermediary between the immersion cooling system and the motherboard. It allows the motherboard to be cooled effectively when immersed while providing a convenient interface for removal and replacement, thus mediating between the conflicting requirements of heat dissipation and accessibility.
