Liquid Cooling Server Cable Sealing for Coolant Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of preventing liquid leakage at locations where data transmission cables are present in liquid cooling servers, particularly where I/O modules are located, has not been adequately addressed in existing technologies.
Innovation Solution
A liquid anti-leakage assembly is integrated into the casing of a liquid cooling server, featuring a cable gland and sealing member to tightly press transmission cables, ensuring separation between wet and dry areas and preventing coolant ingress into the I/O module region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If transmission cables are routed through the casing to connect computing elements and I/O modules, then data transmission functionality is achieved, but coolant leakage risk increases at the cable penetration locations
Solution Approach 1:
The casing is divided into a first cavity containing the computing element and a second cavity containing the I/O module, with the transmission cable passing through a cable gland that seals the boundary between cavities. This segmentation allows data transmission while preventing coolant leakage through the cable penetration point.
Solution Approach 2:
A cable gland is introduced as an intermediary component at the cable penetration location. The cable gland provides a sealing interface that allows the transmission cable to pass through while preventing coolant from leaking along the cable path, thus resolving the contradiction between cable routing and leakage prevention.
2Temperature
If coolant is injected into the casing to immerse heat generating elements, then cooling efficiency is improved, but the risk of coolant affecting I/O module functionality increases
Solution Approach 1:
The internal space of the casing is segmented into two separate cavities: a first cavity for immersing the heat-generating computing element in coolant, and a second cavity for housing the I/O module. This segmentation allows efficient cooling of the computing element while preventing coolant from contacting the I/O module, thus resolving the contradiction between cooling efficiency and protecting I/O module functionality.
3Reliability
If the cable hole is sealed to prevent leakage, then coolant leakage is prevented, but data transmission cable installation becomes difficult
Solution Approach 1:
A cable gland serves as an intermediary component that reconciles the conflicting requirements of sealing and cable installation. The cable gland can be pre-installed in the casing during manufacturing, providing a sealed opening that allows cables to be routed through easily during assembly, thus resolving the contradiction between sealing effectiveness and installation ease.
Solution Approach 2:
The cable gland is pre-installed in the casing during the manufacturing process, creating a prepared sealed opening before final assembly. This preliminary action makes subsequent cable installation straightforward while ensuring coolant leakage prevention, thus resolving the contradiction between sealing and installation ease.
