Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooling devices for electrical assemblies often require reorganization of the cabinet to provide adequate cooling, especially when new apparatuses are added to a nearly full electric cabinet, making it difficult to maintain effective heat management.
Innovation Solution
A cooling device with a first chamber and a second chamber separated by heat exchanger means, featuring a thermoelectric cooling element for moisture condensation and fan-assisted cooling medium flow, allowing for efficient heat transfer and easy maintenance, and the ability to be retrofitted onto existing electric cabinets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the electric cabinet is nearly full with existing apparatuses, then the cabinet space is efficiently utilized, but it becomes difficult to provide adequate cooling when new apparatuses are added
Solution Approach 1:
The cooling device is divided into a first chamber that interfaces with the device chamber and a second chamber that interfaces with the cabinet interior, separated by heat exchanger means. This segmentation allows independent cooling zones where the first chamber provides dedicated cooling to the electrical apparatus while the second chamber handles ambient air exchange, enabling effective cooling even when the cabinet is full.
2Object-affected harmful factors
If the device chamber is isolated from ambient air, then the cooling medium remains clean, but maintenance becomes more complex
Solution Approach 1:
The heat exchanger means extracts and separates the cooling function from the device chamber while maintaining isolation. The first heat exchanger is positioned within the device chamber to provide cooling, while the second heat exchanger is positioned in the cabinet interior, allowing the cooling medium to remain isolated and clean while maintenance can be performed on external components.
3Object-affected harmful factors
If a thermoelectric cooling element is added for moisture condensation, then moisture control is improved, but device complexity increases
Solution Approach 1:
The thermoelectric cooling element is integrated with the heat exchanger means, combining moisture condensation functionality with the existing heat transfer structure. The thermoelectric element is positioned in thermal contact with the heat exchanger, allowing it to condense moisture while utilizing the same thermal pathways, thereby reducing overall device complexity compared to separate systems.
