Air-Cooled Compressor With Integrated Dryer at Motor Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Classic air-cooled compressor installations with integrated dryers face space constraints and stability issues due to the high positioning of the dryer device, which affects transport stability and prevents the use of additional components like sound dampers.
Innovation Solution
The air-cooled compressor installation features an integrated dryer device positioned adjacent to the motor instead of above it, allowing for a lower center of gravity and additional space within the housing for components like sound dampers. This configuration includes a separate dryer housing connected to the bottom wall of the main housing, with a first lateral cooling channel and a second transversal cooling channel that intersect without adversely affecting cooling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the dryer device is positioned above the motor, then the drying function is achieved, but the center of gravity is positioned high making transport unstable
Solution Approach 1:
The patent inverts the conventional positioning of the dryer device by placing it at the bottom of the housing instead of above the motor. This inversion lowers the center of gravity to the bottom surface of the housing, significantly improving transport stability while maintaining the drying function through the desiccant drum mechanism.
2Reliability
If the dryer device is positioned above the motor, then the drying function is achieved, but space for additional components is limited
Solution Approach 1:
By inverting the dryer device position to the bottom of the housing, the patent frees up the upper space previously occupied by the dryer. This newly available space can accommodate additional components such as sound dampers, control units, or expansion tanks, enhancing the system's adaptability and versatility.
3Temperature
If cooling channels are added to cool the dryer housing, then cooling efficiency is improved, but device complexity increases
Solution Approach 1:
The patent implements cooling channels that serve multiple functions: they cool the dryer housing during operation and simultaneously act as heat exchangers during the regeneration phase. This multi-functionality approach improves cooling efficiency without proportionally increasing device complexity, as the same structural elements perform multiple thermal management tasks.

AI summary
An air-cooled compressor installation includes a housing in which a motor and compressor element are arranged, and an integrated dryer device with a dryer housing with an internal space and at least one air-cooled heat exchanger. The dryer device is arranged adjacent to the motor. The heat exchanger connects via a first cooling channel to a lateral cooling channel. The space is connected via a transversal cooling channel to an outlet for a first cooling air flow, which transversal cooling channel extends through the lateral cooling channel.
