Versatile Cooling Housing for Electrical Motor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical motor designs require significant modifications to switch between gas and liquid cooling, including changes to statoric parts and seals, leading to increased production costs and logistical complexities.
Innovation Solution
A versatile cooling housing with alternating higher and smaller cooling fins on the inlet and outlet manifolds allows for either gas or liquid cooling, using the same statoric parts, with a cover plate and seals to create a leak-free cooling path, and is realized through sand casting for effective heat exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If liquid cooling is implemented in electrical motors, then cooling efficiency is improved, but statoric parts require huge modifications including inlet and outlet manifolds
Solution Approach 1:
The housing is designed with a universal cooling system that can function with both liquid and gas cooling media. The housing includes inlet and outlet manifolds with cooling fins that can accommodate either liquid coolant flow or gas circulation, eliminating the need for separate statoric parts designs for different cooling types.
Solution Approach 2:
The cooling system incorporates adjustable and reconfigurable components that allow dynamic adaptation between liquid and gas cooling modes. The manifolds and cooling paths can be configured differently depending on the cooling medium used, providing flexibility without requiring complete redesign of statoric parts.
2Reliability
If liquid cooling is implemented, then additional seals are necessary to avoid internal liquid leakages, but device complexity increases
Solution Approach 1:
The sealing function is merged with the existing housing structure and manifold design. Seals are integrated into the housing features rather than being separate components, and the same housing design supports both liquid sealing and gas containment without requiring additional sealing mechanisms.
3Temperature
If liquid cooling circuit is modified to increase efficiency, then cooling performance is improved, but manufacturing and logistics costs increase
Solution Approach 1:
A single universal housing design serves both liquid and gas cooling applications, eliminating the need for separate manufacturing lines for different cooling types. The housing can be produced once and used for both cooling media, significantly reducing production costs and simplifying logistics while maintaining optimized cooling performance through properly designed manifolds and cooling paths.
4Adaptability or versatility
If complete redesign of statoric parts is required to modify cooling fluid type, then cooling adaptability is improved, but productivity decreases
Solution Approach 1:
The housing design incorporates dynamic configurability that allows the same statoric parts to adapt to different cooling fluid types without redesign. The manifolds and cooling channels can be configured for either liquid or gas cooling through simple assembly variations rather than complete redesign, maintaining high manufacturing productivity while achieving full cooling adaptability.
