Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Container data centers face challenges in dynamically adjusting airflow through fixed air outlets, which limits the ability to optimize heat dissipation across cabinet servers, potentially leading to uneven cooling and reduced system efficiency.
Innovation Solution
The implementation of an airflow adjusting apparatus with rotatable shielding members and a motor system, controlled by a temperature sensor and controller, allows for dynamic adjustment of airflow by increasing or decreasing the opening size of air outlets based on temperature differences between cabinet servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed air outlets are used in the raised floor, then the structure is simple and easy to manufacture, but the airflow cannot be adjusted dynamically leading to uneven cooling
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed air outlets into adjustable outlets. The shielding members can rotate between different positions to dynamically control the opening size of each air outlet, allowing the system to adapt airflow distribution according to the actual cooling needs of different server racks while maintaining a relatively simple overall structure.
2Productivity
If uniform airflow through all air outlets is used, then the system is easy to control, but heat dissipation efficiency is reduced due to uneven server heat generation
Solution Approach 1:
The patent applies the local quality principle by allowing each air outlet to have independent airflow control through individually adjustable shielding members. This enables different airflow rates to be provided to different server racks based on their local heat generation characteristics, optimizing heat dissipation efficiency while the centralized controller maintains operational simplicity.
Solution Approach 2:
The patent applies the feedback principle by using temperature sensors to detect the actual temperature of each server rack and providing feedback to the controller. The controller then adjusts the shielding member positions accordingly to optimize airflow distribution, achieving efficient heat dissipation while maintaining ease of operation through automated control.
3Reliability
If no airflow adjustment mechanism is added, then the device complexity remains low, but the cooling performance cannot be optimized for different operating conditions
Solution Approach 1:
The patent transforms static air outlets into dynamic adjustable outlets by adding rotatable shielding members that can change opening sizes based on cooling demands. This improves cooling performance and system reliability under different operating conditions while adding only moderate structural complexity through the use of simple rotational mechanisms.

AI summary
A heat dissipation system for cabinet servers supported on a raised floor includes a condenser, airflow adjusting apparatus, a controller, and a temperature sensor located at an air outlet of each cabinet server. The raised floor defines air outlets adjacent to each cabinet server. The adjusting apparatus are mounted to the raised floor and aligning with the air outlets. Each of the airflow adjusting apparatus includes a number of shielding members rotatable relative to the raised floor and aligning with the air outlets, and a motor electrically coupled to the controller. The temperature sensors are electrically coupled to the controller. The condenser generates cool air entering the raised floor through the air inlet, to enter the cabinet servers through the airflow adjusting apparatus and the air outlets. The controller controls the shielding members to rotate, to change the opening size of the air outlets of the raised floor.
