Solution Overview
Problem
Heat generated during the operation of electronic components in an air conditioner's electric control box affects their operational stability.
Innovation Solution
An electric control box design featuring a first fan forming first heat dissipation airflow along a first path, which is diverted to form a second airflow path, with electronic components distributed across both paths to carry away heat, and a heat exchanger in a sealed box body to exchange heat with a refrigerant for external discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electronic components are installed in the electric control box, then the air conditioner can operate and control temperature, but heat generated during operation causes temperature rise affecting operational stability
Solution Approach 1:
The patent divides the heat dissipation path into two separate circulation paths (first heat dissipation path and second heat dissipation path) that are spatially separated and distributed. Electronic components are distributed over both paths to ensure effective heat dissipation while maintaining operational stability.
Solution Approach 2:
The patent uses airflow (pneumatic system) to dissipate heat from electronic components. Two fans generate heat dissipation airflows that circulate through designated paths, carrying heat away from electronic components and maintaining their temperature within reliable ranges.
2Reliability
If heat dissipation airflow is directed through a single path, then the structure is simple, but heat dissipation efficiency is insufficient for multiple electronic components
Solution Approach 1:
The heat dissipation system is segmented into two independent circulation paths with separate airflow channels. Each path has its own fan and designated route through the box body, allowing parallel heat dissipation for multiple electronic components while maintaining manageable structural complexity.
Solution Approach 2:
The patent utilizes three-dimensional space within the box body to create spatially separated heat dissipation paths. By distributing electronic components over both paths and utilizing vertical and horizontal space, the system achieves efficient heat dissipation without excessive structural complexity.
