Outdoor unit of air conditioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioners face challenges in effectively controlling the temperature of electronic components within the outdoor unit, particularly during changes in outdoor air temperature, and require separation of the electronic box and heat exchanger for maintenance, which complicates service procedures.
Innovation Solution
The outdoor unit incorporates a heat dissipation module that allows refrigerant to flow through it, contacting a heat sink which is fixed between the heat generating element and a support structure, ensuring secure positioning and easy maintenance by minimizing the need for alignment during assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If an electronic box heat exchanger is provided in an electronic box, then the electronic box can be cooled, but the electronic box must be separated from the outdoor unit for service and maintenance
Solution Approach 1:
The heat exchanger is separated from the electronic box and integrated into the outdoor unit body as an independent component. This segmentation allows the electronic box to be removed and serviced separately while the heat exchanger remains in the outdoor unit, resolving the contradiction between cooling functionality and serviceability.
2Temperature
If outdoor air is introduced into the electronic box for cooling, then the electronic box can be cooled, but it is not easy to effectively control the temperature according to outdoor air temperature changes
Solution Approach 1:
A heat dissipation module with refrigerant flow channels is introduced as an intermediary between the outdoor air and the electronic box. The refrigerant acts as a mediator that can be controlled to transfer heat efficiently, allowing temperature control to be decoupled from direct outdoor air temperature dependence while maintaining effective cooling.
3Reliability
If a heat dissipation module is integrated into the outdoor unit, then heat dissipation reliability is enhanced, but the device complexity increases
Solution Approach 1:
The heat dissipation module is merged with the outdoor unit body structure, integrating the cooling function into the existing outdoor unit framework. This merging approach enhances heat dissipation reliability while minimizing additional complexity by utilizing the existing structural space and components of the outdoor unit.
