Reactor Casing Cutout for Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing reactor designs for hybrid electric vehicles suffer from inadequate heat dissipation properties due to the casing surrounding the combined coil and magnetic core, leading to potential operational instability and inefficient heat release.
Innovation Solution
A reactor design where the magnetic core's outer core portion is exposed through cutouts in the casing, allowing for improved heat dissipation and reduced stress on the combined member, with the option of using a composite material for enhanced thermal conductivity and a heat dissipation member for further efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire combined member is surrounded by the casing, then the reactor is physically protected and fixed, but the heat dissipation properties become unsatisfactory
Solution Approach 1:
The patent extracts the outer core portion from the enclosed space by providing a cutout in the casing. This allows the outer core portion to be exposed to the external environment, enabling heat dissipation while the inner core portion remains protected inside the casing. The cutout selectively removes the enclosing structure only where needed for heat dissipation.
Solution Approach 2:
The casing is designed with different properties in different regions: the majority of the combined member is enclosed for protection, while the outer core portion is locally exposed through the cutout for heat dissipation. This creates a spatially differentiated structure where protection and heat dissipation coexist.
2Temperature
If the outer core portion is exposed through cutouts, then heat dissipation is improved, but the structural enclosure is compromised
Solution Approach 1:
The cutout is strategically designed to extract only the outer core portion from the enclosed space, leaving the inner core portion and other components protected inside the casing. This selective exposure maintains structural integrity while enabling heat dissipation.
Solution Approach 2:
The casing provides comprehensive enclosure for most components while creating a localized opening for the outer core portion. This local modification allows heat dissipation without compromising the overall structural protection of the reactor.
