Compressor Housing Integrated Cooling Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing turbocharger cooling systems require additional material and space for external connections between compressor and bearing housings, which can negatively impact cooling medium flow behavior and increase the number of interfaces needed.
Innovation Solution
A housing design with integrated cooling systems for compressor and bearing housings, where the first and second housing portions are connected with abutment faces forming a cooling medium transition surrounded by a seal, reducing the need for external interfaces and minimizing spatial requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external pipelines are used to connect cooling systems in compressor housing and bearing housing, then cooling medium exchange is enabled, but material expenditure and space requirements increase
Solution Approach 1:
The patent integrates the cooling systems of the compressor housing and bearing housing by forming a common cooling medium transition directly at the interface of the two housing portions. The abutment faces are designed with integrated cooling channel intakes that align to create a shared transition zone, eliminating the need for separate external pipelines and reducing material expenditure while maintaining cooling system connectivity.
2Reliability
If external pipelines are used to connect cooling systems, then cooling medium exchange is enabled, but spatial requirements increase
Solution Approach 1:
The cooling medium transition is nested within the interface region between the compressor housing and bearing housing. The cooling channel intakes of both housing portions are positioned to overlap or align at the abutment face interface, creating a compact integrated transition zone that utilizes the existing spatial relationship between the two housing portions without requiring additional external space.
3Reliability
If external pipelines are used for cooling system connection, then cooling medium exchange is enabled, but negative influence on flow behavior occurs
Solution Approach 1:
The patent extracts the cooling medium transition from the external pipeline system and relocates it to the internal interface region between the housing portions. By removing the external pipeline connection and replacing it with an integrated transition formed by aligned cooling channel intakes at the abutment faces, the harmful flow behavior disturbances caused by external pipelines are eliminated.
4Reliability
If cooling systems are separated with individual supply and discharge lines, then cooling medium exchange is enabled, but number of interfaces and material expenditure increase
Solution Approach 1:
The patent merges the cooling systems of the compressor housing and bearing housing into a connected system through a common cooling medium transition at the interface. This integration reduces the number of interfaces from four (two supply lines and two discharge lines) to a single integrated transition zone, simplifying the overall system while maintaining the ability to exchange cooling medium between the two housing portions.

AI summary
A housing includes a seal, a first portion for receiving a first axial portion of a rotor, and a second portion for receiving a second axial portion of the rotor. The first portion includes a first cooling system having a cooling channel through which cooling medium flows and a first cooling channel intake, and a first abutment face which surrounds the first cooling channel intake. The second portion includes a second cooling system having a cooling channel through which cooling medium flows and a second cooling channel intake, and a second abutment face which surrounds the second cooling channel intake. The housing portions are connected so that the abutment faces rest on each other and the cooling channel intakes form a transition surrounded by the abutment faces. The seal is arranged between the abutment faces and extends around the transition and is spaced apart from the cooling channel intakes.
