Solution Overview
Problem
The electrical equipment box in heat pump apparatuses experiences overheating due to the heat generated by electronic components and the blower room, necessitating an efficient cooling solution.
Innovation Solution
The heat pump apparatus is designed with a configuration that includes a machine room and a blower room within a housing, where the electrical equipment box is positioned above, featuring a cover member with a lower upper surface height than the heat exchanger, allowing for effective ventilation and cooling, and incorporating a heat sink to dissipate heat generated by electronic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electrical equipment box is positioned above the machine room and blower room, then it is easily accessible and structurally simple, but it experiences overheating due to heat from electronic components and the blower room
Solution Approach 1:
The invention introduces a vertical dimension to the cooling solution by positioning the heat exchanger above the electrical equipment box and using gravity-assisted natural convection. Hot air rises from the electrical equipment box, passes through the heat exchanger positioned at a higher elevation, and is cooled before descending back to the box, creating a vertical cooling circulation path that effectively removes heat while maintaining the box's accessible position
2Temperature
If the cover member height is reduced below the heat exchanger height, then ventilation and cooling efficiency are improved, but the electrical equipment box structure becomes more constrained
Solution Approach 1:
The invention merges the cover member with the heat exchanger assembly, where the cover member serves dual functions: protecting the electrical equipment box and facilitating heat exchange. The heat exchanger is integrated into or positioned as part of the cover member structure, eliminating the need for separate cooling components and reducing overall structural complexity while maintaining effective cooling
