Axial Pipe Cooling for Parallel Electromagnetic Coils
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooling structures for electromagnetic coils face interference issues when multiple coils are disposed in parallel, as inlet and outlet pipes overlap, making it difficult to form units or dispose them in parallel configurations.
Innovation Solution
The cooling structure involves attaching a cooling member with a fluid flow path to the end surface of the electromagnetic coil, with inlet and outlet pipes extending through the coil's internal space to connect externally, allowing multiple coils to be disposed in parallel without pipe interference, and utilizing non-magnetic materials and seal members to manage pipe connections and magnetic fluxes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If inlet pipes and outlet pipes are connected to cooling elements at radially opposite end portions of electromagnetic coils, then cooling function is achieved, but pipes interfere with each other when multiple coils are disposed in parallel
Solution Approach 1:
The patent changes the pipe connection location from the radial direction (end portions of the coil) to the axial direction (end surfaces of the coil). This dimensional change allows pipes to extend along the axial direction, enabling parallel arrangement of multiple coils without pipe interference, while maintaining effective cooling coverage.
2Productivity
If multiple electromagnetic coils are disposed in parallel, then system capacity is increased, but pipe interference prevents arbitrary parallel disposition
Solution Approach 1:
By relocating pipe connections to the axial end surfaces and extending pipes along the axial direction, the patent enables multiple coils to be arranged in parallel without spatial interference between pipes, thus increasing system capacity and providing flexible parallel configuration options.
Solution Approach 2:
The cooling structure with axial pipe connections provides a universal configuration that can accommodate multiple parallel coil arrangements. The same cooling element design serves both single coil and multiple parallel coil configurations, enhancing adaptability and versatility.
3Temperature
If cooling elements are attached to end surfaces of electromagnetic coils, then cooling efficiency is improved, but pipe connection becomes complex
Solution Approach 1:
The patent simplifies pipe connection by extending pipes along the axial direction from end surfaces, utilizing the available axial space within the coil structure. This approach reduces connection complexity compared to radial connections while maintaining effective cooling element attachment to end surfaces.
