Solution Overview
Problem
The existing heat dissipation structures for fan drives in air conditioner outdoor units are complicated and inefficient, leading to unstable operation and reduced service life due to high temperatures.
Innovation Solution
A simplified heat dissipation structure is implemented by adding a baffle plate and air vents on the side plate of the air conditioner outdoor unit, creating an air duct that communicates with the inner chamber to enhance heat dissipation without the need for an external heat dissipation device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heat dissipation device is installed on the outer side of the fan drive housing, then heat dissipation is improved, but the structure becomes complicated
Solution Approach 1:
The patent combines the heat dissipation function with the existing side plate structure of the air conditioner outdoor unit. The side plate is designed to cling to the fan drive housing and serves dual purposes: structural support and heat dissipation. This eliminates the need for a separate external heat dissipation device, thereby simplifying the overall structure while maintaining effective heat dissipation.
2Device complexity
If natural heat dissipation is used without additional devices, then the structure is simple, but heat dissipation efficiency is insufficient leading to high temperatures
Solution Approach 1:
The patent introduces air vents as intermediary elements that facilitate heat dissipation. These air vents are formed on the side plate and enable air flow between the indoor unit and outdoor unit, creating an efficient heat dissipation pathway. This intermediary structure significantly improves heat dissipation efficiency compared to natural heat dissipation, while maintaining structural simplicity.
3Temperature
If air vents are added to create an air duct, then heat dissipation efficiency is improved, but the structure becomes more complex
Solution Approach 1:
The air duct structure is merged with the side plate of the air conditioner outdoor unit. The side plate is designed with air vents that communicate with the inner chamber, creating an integrated heat dissipation pathway. This integration ensures that the air duct functionality is achieved without adding separate complex structures, as the side plate itself serves as the heat dissipation channel.
