Window AC Heat Exchanger Assembly With Condensate Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional window air conditioner assembly methods result in low efficiency due to separate installation of indoor air duct shells and heat exchangers, leading to issues with condensed water accumulation and safety hazards from water diversion into electrical components.
Innovation Solution
A window air conditioner design featuring a support frame for integrated installation of the indoor heat exchanger and air duct shell, with a water guide groove system to manage condensed water and a water baffle structure to isolate electrical components from moisture, along with a detachable temperature detection assembly for easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the indoor air duct shell and indoor heat exchanger are separately installed at the chassis and indoor water pan, then the installation flexibility is improved, but the assembly efficiency deteriorates
Solution Approach 1:
The patent combines the indoor air duct shell and indoor heat exchanger into a single integrated assembly that is installed together at the chassis, eliminating the need for separate installation steps and thereby improving assembly efficiency while maintaining installation flexibility
2Ease of manufacture
If the connection pipes are installed at the side plate, then the heat exchanger installation is simplified, but condensed water accumulation and spilling occur
Solution Approach 1:
The patent introduces a water guide groove as an intermediary structure between the connection pipes and the indoor water pan. This groove channels condensed water that accumulates on the side plate away from electrical components and directs it to the water pan, preventing water spilling hazards while maintaining the simplified installation configuration
3Volume of moving object
If the display box is positioned at the front near the indoor heat exchanger, then the space utilization is improved, but condensed water may be diverted into electrical devices
Solution Approach 1:
The water guide groove acts as a protective intermediary structure that intercepts and redirects condensed water before it can reach the display box and other electrical components. This allows the display box to be positioned close to the heat exchanger for better space utilization while preventing water damage through the grooved drainage path
4Measurement precision
If the temperature detector is fixed at the heat exchanger, then the temperature detection function is improved, but the replacement and maintenance difficulty increases
Solution Approach 1:
The patent segments the temperature detector from the heat exchanger body by providing it with a separate mounting structure that allows independent removal and installation. This segmentation enables the temperature detector to maintain its fixed position for accurate temperature detection while being easily replaceable for maintenance purposes

AI summary
An indoor heat exchanger includes a heat exchanger shell, a side plate structure including shell side plates arranged at both ends of the heat exchanger shell, heat exchange fins installed at the shell side plates provided in the heat exchanger shell, refrigerant pipes passing through the heat exchange fins, and connection pipes protruding from an end of the heat exchanger shell and each connected to ends of two refrigerant pipes on same side.
