Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical circuit cooling methods, such as using ambient air, are inefficient for heat dissipation, and direct contact with cooling fluids is often incompatible with electrical components, necessitating a solution that efficiently conveys cooling fluid while maintaining a leak-resistant separation.
Innovation Solution
A metal extrusion assembly with axial cooling conduits and end caps forming fluid-tight seals, allowing cooling fluid to flow through and dissipate heat from electrical components, while a cover protects the components from external harm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If cooling fluid is placed in close proximity to electrical components, then heat removal efficiency is improved, but risk of fluid leakage and component incompatibility increases
Solution Approach 1:
The assembly is divided into separate functional zones: an electrical component mounting area and a cooling fluid flow area. The cooling conduits are segmented into multiple channels within the mounting base, allowing independent fluid flow paths that are physically separated from electrical components by fluid-tight seals and spacing features.
Solution Approach 2:
The mounting base acts as an intermediary structure between the cooling fluid and electrical components. It provides fluid-tight seals, spacing features, and thermal pathways that transfer heat from components to the cooling fluid without allowing direct contact or leakage between the two domains.
2Loss of energy
If cooling conduits are integrated into the mounting base, then heat dissipation efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The cooling conduits are merged with the mounting base as an integrated structure. The mounting base simultaneously provides mechanical support for electrical components, thermal pathways for heat dissipation, and fluid-tight containment for cooling fluid, combining multiple functions into a single manufactured part.
Solution Approach 2:
The mounting base is designed as a multi-functional component that serves as both a structural support for electrical components and a cooling system housing. It integrates fluid-tight seals, spacing features, and thermal pathways, allowing a single part to perform multiple critical functions in the assembly.

AI summary
An auxiliary-cooled electronics assembly comprises a metal extrusion that includes: one or more cooling conduits extending axially along a length of the metal extrusion with a first open end in fluid communication with the cooling conduit(s); and a second open end in fluid communication with the cooling conduit(s); a first end cap coupled to the first open end forming a fluid-tight seal between the first end cap and the metal extrusion; a second end cap coupled to the second open end forming a fluid-tight seal between the second end cap and the metal extrusion; and one or more electrical circuit components, electrically linked together to form an electrical circuit, mounted to the metal extrusion.
