Embedded type air conditioner outdoor unit and an air conditioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Embedded air conditioners suffer from significant noise due to their axial-flow fan design, which also results in an incompact space structure.
Innovation Solution
The embedded type air conditioner outdoor unit incorporates a cross-flow fan and a V-shaped heat exchanger arrangement within a housing with sealed side walls, utilizing a cross-flow fan to expel heated air through a dual outlet configuration, reducing noise and vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If an axial-flow fan is used in the embedded air conditioner, then the space structure can be simple, but the noise level increases significantly
Solution Approach 1:
The patent changes the fundamental operating parameters of the fan by switching from an axial-flow design to a cross-flow design. This parameter change fundamentally alters the airflow pattern and noise characteristics, resolving the contradiction by achieving both compactness and reduced noise through a different operational mode rather than simply modifying the axial-flow fan geometry
2Object-generated harmful factors
If a cross-flow fan is used instead of axial-flow fan, then noise is reduced, but the space structure becomes more complex
Solution Approach 1:
The patent merges the cross-flow fan with the heat exchanger assembly, integrating multiple functions into a unified structure. The fan is positioned to work in conjunction with the V-shaped heat exchanger bodies, combining the airflow generation function with the heat exchange function in a space-efficient manner that resolves the complexity issue
3Productivity
If V-shaped heat exchanger bodies are arranged with opening ends facing the air inlet, then heat exchange efficiency is improved, but the structural complexity increases
Solution Approach 1:
The patent employs asymmetric V-shaped arrangement of the heat exchanger bodies where the opening ends face the air inlet. This asymmetric configuration optimizes the airflow path and heat exchange surface exposure to the incoming air, improving heat exchange efficiency while the symmetry of the V-shape itself provides structural regularity that mitigates the complexity increase

AI summary
The present disclosure relates to an embedded type air conditioner outdoor unit and an air conditioner. The embedded type air conditioner outdoor unit comprises: a housing comprising an air inlet and an air outlet which are provided on the same side surface of the housing; a heat exchanger provided within the housing, for heat exchange with air introduced by the air inlet; and a cross-flow fan provided within the housing, for flowing the air introduced by the air inlet through the heat exchanger. By applying the technical solution of the present application, the air introduced by the air inlet after heat exchange by the heat exchanger is expelled via an exhaust port by using the cross-flow fan, thereby improving the problem of much noise of the embedded type air conditioner outdoor unit.
