Seamless Extruded Server Case for Liquid Submersion Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid submersion cooled computers face challenges in maintaining a leak-proof environment due to seams and openings in their housings, which can lead to leakage and reduced efficiency in heat management.
Innovation Solution
A seamless extruded main body is used to form a liquid-tight case for the computer, eliminating seams and openings in the walls, with a dielectric cooling liquid submerging heat-generating components, and incorporating a valved inlet and outlet for controlled liquid flow, while using ridges and threaded holes for secure attachment of end walls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional housings with seams and openings are used, then ease of manufacture and assembly is improved, but reliability deteriorates due to leakage paths
Solution Approach 1:
The patent merges multiple separate wall panels into a single seamless extruded structure. Instead of assembling multiple panels with seams, the housing is formed as one continuous piece through extrusion, eliminating leakage paths at joints while maintaining manufacturing feasibility through standardized extrusion processes.
Solution Approach 2:
The extruded housing is designed with integrated attachment features including ridges and threaded holes that segment the structure into attachable sections. This allows the housing to be assembled with end walls and other components through threaded fasteners, combining the leak-proof benefit of seamless construction with the assembly flexibility of segmented design.
2Reliability
If seams and joints are present in the housing, then ease of manufacture is improved, but reliability deteriorates due to potential leakage at joints
Solution Approach 1:
Multiple wall panels that would traditionally be separately manufactured and joined are merged into a single extruded component. This eliminates the need for seams and joints in the main housing structure, ensuring liquid-tight sealing while using a established manufacturing process.
Solution Approach 2:
The extruded housing incorporates localized features such as ridges and threaded holes at specific positions to enable attachment of end walls and other components. This allows the majority of the housing to remain seamless for reliability while providing localized attachment points for assembly requirements.
3Reliability
If openings are provided in the housing walls, then ease of operation and component access is improved, but reliability deteriorates due to potential liquid leakage through openings
Solution Approach 1:
Access openings are extracted from the main housing walls and relocated to the removable end walls. This allows the main housing to remain completely sealed while providing access points through the end walls that can be opened or removed for component installation and maintenance without compromising the liquid-tight enclosure.
Solution Approach 2:
The end walls are designed to be removable or openable, providing dynamic access to the interior space. This allows the housing to maintain its sealed state during operation while enabling easy access for maintenance, installation, and component replacement when needed.

AI summary
A liquid submersion cooled computer that includes a seamless, extruded main body used to form a liquid-tight case holding a cooling liquid that submerges components of the computer. By forming the main body as a seamless extrusion, the number of possible leakage paths from the resulting liquid-tight case is reduced. No seams are provided on the main body, and there are no openings through the walls of the main body, so liquid cannot leakage through the main body. Any leakage paths are limited to joints between the main body and end walls which are sealingly attached to the main body to form the liquid-tight case.
