Solution Overview
Problem
In air conditioners, the charged state of air flowing through the heat exchanger affects its heat exchange efficiency, leading to turbulent airflow and reduced operating efficiency due to positive charging of non-conductive materials like resin components.
Innovation Solution
A reticular resin molding composed of a thermoplastic resin with a montmorillonite-based clay mineral powder, applied in a plate form with vent holes, is used to control the air charge and improve heat exchange efficiency by stabilizing the airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a reticular resin molding with fired ceramic powder is used to increase heat exchange efficiency, then heat exchange efficiency is improved, but the resin molding becomes positively charged causing turbulent airflow and reduced operating efficiency
Solution Approach 1:
The patent changes the material parameter from fired ceramic powder to non-fired ceramic powder, which fundamentally alters the electrostatic properties of the resin molding. This parameter change eliminates positive charging while maintaining the heat exchange enhancement benefits, thereby resolving the contradiction between heat exchange efficiency and operating efficiency
Solution Approach 2:
The patent uses a composite material consisting of non-fired ceramic powder dispersed in resin. This composite structure provides both the heat exchange enhancement properties of ceramic materials and the electrostatic control benefits of non-fired ceramic particles, allowing simultaneous improvement of heat exchange efficiency and operating efficiency
2Stability of the object's composition
If non-fired ceramic powder is used instead of fired ceramic powder, then positive charging is suppressed and airflow stability is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The patent changes the thermal processing parameter from fired to non-fired state, which simplifies the manufacturing process by eliminating high-temperature sintering while maintaining the functional benefits of ceramic powder in the resin matrix
Solution Approach 2:
The reticular structure with through-holes provides a straightforward manufacturing approach using conventional molding techniques, making the non-fired ceramic powder composite easy to manufacture while maintaining airflow stability
