Solution Overview

Problem

Container data centers face challenges in dynamically adjusting airflow through fixed air outlets, which limits the ability to optimize heat dissipation and maintain proper server functioning due to constant airflow rates.

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

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed air outlets are used in the raised floor, then the structure is simple and manufacturing is easy, but the airflow cannot be adjusted dynamically to optimize heat dissipation

Engineering Contradiction:
Improveairflow adjustabilityVSAvoidoutlet structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by transforming the fixed air outlets into adjustable outlets. Shielding members are installed at the air outlets of the raised floor, allowing the opening sizes to be dynamically changed. This enables the system to adapt airflow rates to different heat dissipation requirements while maintaining a relatively simple overall structure, thus resolving the contradiction between adaptability and device complexity.

Inventive Principle:
Principle #15Dynamics

2Temperature

If the opening size of air outlets is increased to improve heat dissipation, then more cool air can enter the server racks, but the energy loss increases and cooling efficiency decreases

Engineering Contradiction:
Improveserver cooling effectivenessVSAvoidcooling energy loss
Core Design Contradiction:
TemperatureVSLoss of energy

Solution Approach 1:

The patent applies parameter changes by allowing the opening sizes of air outlets to be adjusted according to actual cooling needs. Instead of maintaining fixed large openings that cause energy loss, the shielding members enable dynamic adjustment of opening parameters. This ensures optimal balance between heat dissipation effectiveness and energy conservation by matching airflow rates to actual server heat generation requirements.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If constant airflow rates are maintained through fixed outlets, then the system is simple to operate, but the heat dissipation cannot be optimized for varying server loads

Engineering Contradiction:
Improveheat dissipation efficiencyVSAvoidairflow management complexity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent applies self-service by implementing a control system that automatically adjusts the shielding member positions based on temperature sensor feedback. The controller receives temperature information from sensors positioned near server racks and autonomously modifies airflow rates without requiring manual intervention. This enables optimized heat dissipation for varying server loads while maintaining ease of operation through automated control.

Inventive Principle:
Principle #25Self-service

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.
