Integrated Cooling Sleeve Housing for Compact Motor Thermal Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotary mechanical systems, such as electric motors and compressors, require a separate cooling sleeve that increases assembly time and cost and housing size, which is inefficient.
Innovation Solution
Integrate cooling channels directly into the housing of the rotary mechanical system, eliminating the need for a separate cooling sleeve by machining channels within the housing to allow cooling fluid to flow and draw heat away from the motor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a separate cooling sleeve is used to cool the motor, then the motor cooling function is achieved, but the assembly time and housing size increase
Solution Approach 1:
The cooling channels are integrated directly into the housing structure, merging the housing and cooling sleeve into a single component. This eliminates the need for separate assembly of a cooling sleeve, reducing assembly time and complexity while maintaining the motor cooling function through refrigerant flow through the integrated channels
2Temperature
If a separate cooling sleeve is used to cool the motor, then the motor cooling function is achieved, but the housing size increases
Solution Approach 1:
The cooling channels are formed as integral parts of the housing through machining operations, eliminating the need for an additional cooling sleeve component. This integration reduces the overall housing volume by removing redundant structural elements while preserving the cooling channels' ability to dissipate motor heat
3Device complexity
If cooling channels are integrated into the housing, then assembly time and housing size are reduced, but manufacturing complexity increases
Solution Approach 1:
The cooling channels are machined into the housing during the initial manufacturing process before final assembly. This preliminary action incorporates the cooling function into the housing fabrication stage, eliminating subsequent assembly steps and reducing overall assembly complexity despite requiring precision machining operations
