Dual-Chamber Server Cooling Layout for Low-Loss Liquid Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing server cooling systems using liquid cooling methods face issues with liquid splashing during maintenance and cumbersome liquid replacement processes due to the need to lift and drain all servers.
Innovation Solution
A server design with separate containment chambers for primary and secondary heat generation components, where primary components are immersed in cooling liquid and secondary components are isolated, allowing for efficient heat dissipation with minimal liquid usage, and maintenance is facilitated by liquid drainage through dedicated outlets without lifting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If servers are placed in a container filled with cooling liquid for heat dissipation, then cooling efficiency is improved, but liquid splashing occurs during lifting and draining causing loss
Solution Approach 1:
The server is divided into two independent containment chambers: a first containment chamber for primary heat generation components (CPU, GPU) and a second containment chamber for secondary heat generation components. The second chamber is sealed and isolated from the first chamber, allowing selective access to the primary chamber for maintenance without moving the entire server, thereby preventing liquid splashing and loss.
2Loss of substance
If all servers are lifted out for cooling liquid replacement, then liquid replacement is achieved, but the process becomes cumbersome and time-consuming
Solution Approach 1:
The first containment chamber is designed as a separable module that can be independently removed from the server assembly. This allows the cooling liquid in the primary chamber to be drained and replaced without lifting or moving the entire server or the secondary containment chamber, significantly reducing replacement time and operational complexity.
Solution Approach 2:
The first containment chamber containing the primary heat generation components and cooling liquid is extracted as an independent unit. This extracted module can be drained and refilled separately, enabling rapid cooling liquid replacement without affecting the rest of the server system.
3Device complexity
If primary and secondary heat generation components share the same containment chamber, then structure is simplified, but cooling liquid usage increases and maintenance becomes difficult
Solution Approach 1:
The server is segmented into two independent containment chambers: the first chamber contains primary heat generation components and uses cooling liquid, while the second chamber contains secondary heat generation components and is sealed without cooling liquid. This segmentation reduces the total volume of cooling liquid required while enabling independent maintenance of the primary chamber.
Solution Approach 2:
Different containment strategies are applied to different components based on their heat generation characteristics. Primary heat generation components are placed in an open containment chamber with cooling liquid for active cooling, while secondary heat generation components are placed in a sealed containment chamber without cooling liquid, optimizing both cooling efficiency and liquid usage.

AI summary
A server includes a first chassis, a second chassis, a primary heat generation component, and a secondary heat generation component. The first chassis has a first containment chamber, and the primary heat generation component is arranged within the first containment chamber. The first chassis also has a first liquid inlet and a first liquid outlet which are both in communication with the first containment chamber. The second chassis is arranged at one end of the first chassis and has a second containment chamber. The second containment chamber is sealed and isolated from the first containment chamber. The secondary generation component is arranged in the second containment chamber.
