Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In densely arranged server systems, efficient heat dissipation is crucial to prevent server damage from excessive heat generation, as existing solutions fail to effectively remove heat from the densely packed servers.
Innovation Solution
A server system incorporating a heat dissipation device with a first fan module, a second fan module, and an ice water heat exchanger, where the first fan module draws cooling air from the heat exchanger and distributes it through ventilation holes and grooves in the racks to exchange heat with servers, while the second fan module draws heated air to the heat exchanger for external dissipation, maintaining low server temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If servers are densely arranged in a cabinet to increase productivity, then the quantity of servers per cabinet is improved, but heat dissipation efficiency deteriorates due to insufficient cooling
Solution Approach 1:
The cooling system is segmented into multiple independent fan modules (first fan module with multiple first fans, second fan module with multiple second fans) positioned at different locations within the cabinet. Each fan module independently manages airflow for specific server rows, enabling localized cooling control that maintains effectiveness even as server density increases throughout the cabinet.
Solution Approach 2:
Different regions of the cabinet receive customized cooling approaches: the first fan module provides cooling for servers in lower rows through front-side airflow, while the second fan module handles servers in upper rows through rear-side airflow. This localized cooling strategy ensures that each server region receives appropriate cooling regardless of overall cabinet density.
2Device complexity
If conventional cooling methods are used, then device complexity is kept low, but heat dissipation effectiveness deteriorates in densely packed server configurations
Solution Approach 1:
The cooling system divides the cabinet into multiple cooling zones using separate fan modules positioned at different heights and orientations. Each module independently serves specific server rows, ensuring that cooling effectiveness is maintained across the entire cabinet without requiring a single complex centralized cooling system.
Solution Approach 2:
The patent introduces intermediate cooling structures including guide plates and airflow channels that direct cooling air from fan modules to specific server regions. These intermediaries optimize airflow distribution and ensure effective heat removal without requiring overly complex cooling apparatus.
