Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity and increased manufacturing cost of turbochargers due to the additional cooling device installed between the low-pressure and high-pressure compressor housings in two-stage turbochargers complicate the structure and hinder efficient air cooling.
Innovation Solution
A compressor housing with an integrated cooling chamber and cooling water path surrounding the impeller, featuring an annular shape with separate exits for cooling water inflow and outflow, simplifies the structure by providing effective air cooling within the turbocharger.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If an additional cooling device is installed between the low-pressure compressor housing and the high-pressure compressor housing, then air cooling effectiveness is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The cooling device is merged with the compressor housing to form an integrated structure. The housing includes an air passage for compressed air flow and a cooling water passage for cooling water flow, with the two passages positioned to enable heat exchange between the air and cooling water. This integration eliminates the need for separate cooling devices while maintaining effective air cooling.
2Temperature
If an additional cooling device is installed between the low-pressure compressor housing and the high-pressure compressor housing, then air cooling effectiveness is improved, but manufacturing cost increases
Solution Approach 1:
The cooling device is merged with the compressor housing to form an integrated structure. The housing includes an air passage for compressed air flow and a cooling water passage for cooling water flow, with the two passages positioned to enable heat exchange between the air and cooling water. This integration eliminates the need for separate cooling devices while maintaining effective air cooling.
3Temperature
If a separate cooling device is used between compressor housings, then air cooling function is achieved, but the turbocharger structure becomes complicated
Solution Approach 1:
The compressor housing serves multiple functions: it contains the air passage for compressed air flow, incorporates the cooling water passage for cooling water flow, and provides the structural support for the turbocharger assembly. This multi-functionality eliminates the need for separate cooling devices and simplifies the overall turbocharger structure.
