Solution Overview
Problem
Conventional outdoor machines for air conditioners suffer from air stagnation near the heat radiation part, leading to insufficient airflow through the ventilation flue, which limits the cooling capacity of the heat radiation part.
Innovation Solution
The introduction of a vent deflector that covers the heat radiation part, forming a ventilation flue through which air generated by the blower flows, with the outlet of the ventilation flue located on the windward side of the bell mouth, reducing air stagnation and pressure loss, allowing for increased airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the heat radiation part is disposed adjacent to the front panel and bell mouth to form a closed space, then the structure is compact, but air stagnation occurs on the leeward side reducing cooling capacity
Solution Approach 1:
The vent deflector is divided into a windward side deflector and a leeward side deflector that are positioned at different locations. The windward side deflector is disposed at a position advanced toward the windward side relative to the leeward side, creating segmented airflow paths that prevent stagnation while maintaining compact structure.
Solution Approach 2:
The invention introduces a dimensional arrangement where the windward side deflector is positioned forward (advanced toward windward side) relative to the leeward side deflector. This creates a three-dimensional airflow path configuration that eliminates dead zones and ensures continuous air circulation through the heat radiation part.
2Device complexity
If the ventilation flue outlet is located on the leeward side, then the structure is simple, but pressure loss increases and airflow is insufficient
Solution Approach 1:
The vent deflector is designed to be movable relative to the heat radiation part, allowing adjustment of the airflow path. The windward side deflector can be positioned to actively guide air flow toward the outlet, dynamically optimizing the airflow velocity and reducing pressure loss while maintaining a relatively simple overall structure.
3Speed
If the vent deflector covers the entire heat radiation part, then airflow is directed efficiently, but the structure becomes complex and space is reduced
Solution Approach 1:
Instead of providing a single large vent deflector covering the entire heat radiation part, the invention uses two smaller deflectors positioned at specific locations: the windward side deflector at the front and the leeward side deflector at the rear. Each deflector performs a localized function to guide airflow efficiently, reducing overall structural complexity while maintaining effective airflow direction.
