Electric Turbocharger Diffuser Plate for Heat Transfer and Gas Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric turbochargers face challenges in effectively dissipating heat from the stator and maintaining electrical insulation and gas sealing between the diffuser plate and the stator, which affects heat removal performance and efficiency.
Innovation Solution
The electric turbocharger incorporates a heat dissipation member between the diffuser plate and the stator, along with a seal member to prevent gas leakage, and a seal groove to ensure electrical insulation, enhancing heat transfer and sealing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heat dissipation member is disposed between the diffuser plate and the stator, then heat removal performance is improved, but device complexity increases
Solution Approach 1:
A heat dissipation member is introduced as an intermediary component between the stator and diffuser plate. This member facilitates heat transfer from the stator to the diffuser plate, improving heat removal performance without requiring direct contact or complex integrated cooling structures.
2Ease of operation
If gas can pass between the diffuser plate and stator, then ease of operation is improved, but heat dissipation effectiveness deteriorates
Solution Approach 1:
The harmful factor (gas) is extracted or blocked from interfering with the heat dissipation process. A seal member is positioned between the diffuser plate and stator to prevent gas from reaching the heat dissipation member, ensuring that heat transfer is not compromised by gas interference while still allowing operational flexibility.
3Manufacturing precision
If the seal groove is formed in the heat dissipation member installation portion, then manufacturing precision is improved, but electrical insulation reliability deteriorates
Solution Approach 1:
The seal groove is positioned in a different spatial location (dimension) relative to the coil, specifically in the seal member installation portion that protrudes from the heat dissipation member installation portion. This spatial separation ensures that the seal groove can be precisely formed for manufacturing accuracy while maintaining adequate electrical insulation distance from the coil.
