Multi-Blower Cooler Layout for Uniform Display Panel Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coolers for large digital display devices face issues with non-uniform airflow distribution and loss of cooling efficiency due to the use of large fans, leading to temperature inconsistencies and potential deterioration of the display panel.
Innovation Solution
A cooler design featuring a housing with multiple groups of small air blowers, a guide vane, and auxiliary guide vanes to direct airflow uniformly across the display panel, enhancing airflow distribution and reducing airflow loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a large-sized fan is used to increase cooling performance, then the cooling efficiency is improved, but the size of the housing and entire blower is increased
Solution Approach 1:
The patent divides a single large fan into multiple small-sized fans (first and second fans) that operate simultaneously. This segmentation allows the cooling function to be distributed across multiple smaller components, reducing the housing size while maintaining or improving cooling efficiency through parallel operation and better airflow distribution.
2Volume of moving object
If multiple small-sized blowers are arranged and operated simultaneously to reduce blower size, then the housing size is reduced, but non-uniformity and loss of air flow rate occur
Solution Approach 1:
The patent introduces guide vanes as intermediary components between the multiple fans and the display panel. These guide vanes actively direct and regulate the airflow from each fan, ensuring uniform distribution across the display panel surface. The guide vanes mediate the airflow to prevent non-uniformity and minimize loss, resolving the reliability issue while maintaining the compact multi-fan design.
3Volume of moving object
If multiple small-sized blowers are arranged and operated simultaneously to reduce blower size, then the housing size is reduced, but air flow rate loss increases
Solution Approach 1:
The guide vanes serve as intermediary elements that efficiently channel airflow from multiple small fans toward the display panel. By properly directing the airflow paths, the guide vanes minimize turbulence and flow separation, reducing energy losses and maximizing the effective air flow rate reaching the display panel, thus compensating for the potential losses from using multiple smaller blowers.

Implementation Method 1
a guide vane disposed above the air blowing unit and guiding air that flows out from the air blowing unit to flow in different directions
Implementation Method 2
a plurality of auxiliary guide vanes disposed between the air blowing unit and the guide vane, each of the auxiliary guide vane being disposed in each of the groups each including two air blowers, so as to guide air flowing below the air blowing unit to flow toward the guide vane
Implementation Method 3
an air blowing unit disposed inside the housing and sucking external air and blowing the external air in the housing
