Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air cooling systems in servers waste energy by delivering excessive airflow to all components equally, despite varying heat dissipation needs, leading to inefficient heat dissipation and increased energy consumption.
Innovation Solution
An airflow regulation and control apparatus with a windshield and sliding rectangular plate, featuring a lifting wing that blocks airflow when wind strength increases, redirecting excess airflow through a ventilation hole to components with higher calorific values, optimizing airflow distribution and reducing energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If uniform airflow is delivered to all electronic components, then heat dissipation coverage is ensured, but energy consumption increases due to excessive airflow for low-calorific components
Solution Approach 1:
The airflow regulation apparatus segments the uniform airflow into differentiated streams using a baffle structure with through-holes. The baffle divides the airflow path, allowing high-calorific components to receive sufficient cooling air while low-calorific components receive reduced airflow, thereby reducing overall energy consumption while maintaining adequate heat dissipation coverage
Solution Approach 2:
The apparatus applies local quality by creating non-uniform airflow distribution tailored to different component zones. High-calorific value components receive higher airflow density through direct paths, while low-calorific value components receive reduced airflow, optimizing cooling efficiency for each specific thermal load requirement
2Reliability
If airflow is increased to meet the highest calorific value component requirements, then heat dissipation effectiveness improves, but energy waste occurs due to excessive airflow for lower calorific value components
Solution Approach 1:
The baffle structure incorporates a lifting wing that dynamically adjusts the baffle position based on airflow pressure. When fan speed increases, the lifting wing rises, automatically adjusting the airflow distribution to match the actual thermal requirements, thereby maintaining heat dissipation effectiveness while reducing energy waste during low-load conditions
Solution Approach 2:
The apparatus changes the airflow distribution parameters by using the lifting wing mechanism to adjust the baffle angle and position. This dynamic parameter adjustment allows the system to optimize the balance between heat dissipation effectiveness and energy consumption based on varying thermal loads and fan operating conditions

Implementation Method 1
A lifting wing is arranged on the rectangular plate. The lifting wing is blown by an airflow to generate upward lifting force, and drives the rectangular plate to moved upwardly
Implementation Method 2
the rectangular plate is lifted by means of power provided by the lifting wing disposed thereon, and the rectangular plate blocks the airflow, so that the airflow flows through the ventilation hole

AI summary
The disclosure provides an airflow regulation and control apparatus. A ventilation hole is formed in a windshield in a penetrating manner; a rectangular plate is mounted on the windshield; the rectangular plate is lifted by means of power provided by a lifting wing disposed thereon, and the height of the rectangular plate when moving upwards exceed the height of an upper edge of a main body portion of the windshield; when wind strength is low, the rectangular plate is located at a lower portion under the action of gravity and shields the ventilation hole; when the wind strength is increased, the lifting wing is blown by an airflow to generate upwards lifting force, and drives the rectangular plate to moved upwardly so as to shield an opening in an upper portion of the windshield and block the airflow.
