Cyclone Filter for Dust-Free Display Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in maintaining efficient heat dissipation and filter management, especially in outdoor environments where dust and temperature variations are significant.
Innovation Solution
The display device incorporates a cyclone filter at the air intake to remove dust and a circulation system with fans to enhance air flow and heat dissipation, allowing for easy maintenance and permanent use of the filter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a general filter is used for heat dissipation air intake, then dust removal is achieved, but periodic cleaning and replacement are required which complicates maintenance
Solution Approach 1:
The cyclone filter enables the system to clean the air automatically without external intervention. The centrifugal force generated by the rotating airflow separates dust particles from the air stream, and the collected dust is automatically discharged through the dust outlet, eliminating the need for manual cleaning or replacement operations.
Solution Approach 2:
The patent replaces the mechanical filter structure (which requires physical cleaning and replacement) with a cyclone separation system that uses centrifugal force generated by airflow. This mechanical-to-aerodynamic substitution eliminates the need for maintainable filter media while achieving the same dust removal function.
2Temperature
If outside air is introduced for heat dissipation, then cooling efficiency is improved, but dust and contaminants are introduced into the display device
Solution Approach 1:
The cyclone filter acts as an intermediary between the outside air and the display device interior. It receives the raw outside air, separates the harmful dust particles through centrifugal action, and delivers only the cleaned air to the display device, thus mediating between the cooling requirement and the contamination risk.
3Object-affected harmful factors
If filters are replaced periodically, then dust removal effectiveness is maintained, but filter waste is generated and environmental impact increases
Solution Approach 1:
The cyclone filter system recovers the dust particles by collecting them in a separate chamber and discharging them through a dedicated dust outlet. This separation and recovery mechanism eliminates the need to discard the entire filter assembly, allowing the filterless system to continuously operate without generating waste materials.

Implementation Method 1
a cyclone filter located at the first opening and removing dust from the air introduced into the housing. The cyclone filter may include: a cylindrical filter case; a gas inlet through which air is introduced into the filter case; a dust outlet through which dust separated from the air introduced into the filter case is discharged outside
Implementation Method 2
a suction fan configured to suck in dust so that the dust is introduced through the gas inlet
Implementation Method 3
a circulation fan configured to supply air from the second space to the first space
