Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Clogging of heat exchangers in cooling assemblies due to contaminant particles in the cooling air flow is a persistent issue that existing technologies have not adequately addressed.
Innovation Solution
A cooling assembly design featuring a first dust tray located between two heat exchanger units, which directs and captures contaminant particles from the cooling air flow, preventing them from reaching the heat exchanger units and incorporating a control system for automatic cleaning operations to maintain the heat exchanger's efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heat exchanger units are used in cooling assemblies, then heat transfer efficiency is improved, but contaminant particles in cooling air flow cause clogging of the heat exchanger
Solution Approach 1:
A dust tray is introduced as an intermediary component between the cooling air flow and the heat exchanger units. The dust tray captures contaminant particles from the cooling air, preventing them from reaching and clogging the heat exchanger fins, thus protecting the heat exchanger while maintaining its heat transfer efficiency
Solution Approach 2:
The dust tray is positioned to intercept and capture contaminant particles before they can reach the heat exchanger units. This preliminary action of particle capture prevents the harmful clogging effect from occurring in the first place, maintaining reliable heat exchanger operation
2Productivity
If cooling air flow is directed through heat exchanger units, then cooling efficiency is improved, but contaminant particles are carried to the heat exchanger causing blockage
Solution Approach 1:
The dust tray serves as a mediator that intercepts contaminant particles from the cooling air flow before they can be transported to the heat exchanger units. This allows the cooling air flow to continue efficiently while removing the harmful particle transport component
Solution Approach 2:
The dust tray extracts and removes contaminant particles from the cooling air flow by capturing them on its surface. This separation removes the harmful particles from the air stream, allowing the cooling function to continue without particle transport to the heat exchanger
