Display Cooler Airflow Layout for Uniform Panel Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coolers for large digital display devices suffer from non-uniform air flow rates and efficiency losses due to the use of large fans, leading to uneven temperature distribution 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, ensuring even cooling by dividing airflow into front and rear channels within the display device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a large-sized fan is used to increase cooling performance, then cooling efficiency is improved, but the size of the housing and entire blower is increased
Solution Approach 1:
The patent divides the single large fan into multiple small-sized fans (at least three fans: first fan, second fan, and third fan). Each fan handles a specific region, with the first fan cooling the central region, the second fan cooling the left region, and the third fan cooling the right region. This segmentation allows achieving comprehensive cooling coverage without requiring a single large blower housing.
2Volume of moving object
If multiple small-sized blowers are arranged and operated simultaneously, then blower size is reduced, but air flow rate uniformity and efficiency are degraded
Solution Approach 1:
The patent implements local quality by assigning different fans to different spatial regions: the first fan is positioned to cool the central region, the second fan to cool the left region, and the third fan to cool the right region. Each fan is optimized for its specific zone, ensuring uniform air flow distribution across the entire display panel surface despite using multiple small fans instead of a single large fan.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution achieves uniform cooling of the display unit, reducing temperature differences and increasing airflow efficiency by up to 12.6%, thereby preventing panel deterioration and enhancing overall cooling performance.
Implementation Method 1
a cooler mainly uses a blower to cool a display panel by blowing air by revolving a fan
Implementation Method 2
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

AI summary
A cooler and a display device including the cooler. The cooler includes: a housing; an air blowing unit disposed inside the housing and sucking external air and blowing the external air in the housing, wherein the air blowing unit includes a plurality of groups each including two air blowers; a guide vane disposed above the air blowing unit and to guide air flowed out from the air blowing unit to flow in different directions; and a plurality of auxiliary guide vanes disposed between the air blowing unit and the guide vane, and each 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.
