Suction Device Internal Cooling Duct to Reduce Loss and Contamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional suction devices face inefficiencies in cooling their components due to the use of external ambient air, which leads to high losses and potential contamination, as well as inadequate cooling access for components like electronics and power cables, resulting in potential damage and failure.
Innovation Solution
A suction device design that draws cooling air from its internal space and directs it through a duct past the components to be cooled, minimizing the distance cooling air travels and reducing contamination risks, with preferred arrangements such as sloping ducts and secure component holders to enhance cooling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling air is drawn from the environment of the suction device, then cooling air can be supplied to components, but long feed ducts are required resulting in high losses and potential contamination
Solution Approach 1:
Instead of drawing cooling air from the external environment into the housing, the patent inverts the approach by extracting cooling air from the interior space of the housing where hot air accumulates. This reverse flow direction eliminates the need for long external feed ducts, reduces cooling losses, and prevents contamination from external air sources.
2Temperature
If cooling air is drawn from the environment of the suction device, then cooling air can be supplied to components, but dust or dirt may enter the interior of the suction device
Solution Approach 1:
The patent creates a controlled internal atmosphere by circulating air within the housing rather than introducing external air. The cooling air is drawn from the interior space where it is already contained, forming a closed-loop system that prevents dust and dirt from the external environment from entering and contaminating sensitive components.
3Volume of stationary object
If suction device components are arranged within the housing in close proximity, then space is optimized, but access for cooling air is poor or inadequate
Solution Approach 1:
The patent segments the housing interior into distinct cooling zones with dedicated extraction points positioned near heat-generating components. By dividing the cooling function into multiple localized extraction points rather than relying on a single general circulation system, adequate cooling access is achieved even with components arranged in close proximity within the compact housing.

AI summary
A suction device having a duct for supplying cooling air for at least one component of the suction device, wherein the at least one component of the suction device is arranged within a housing of the suction device. The duct is designed in such a way that cooling air is drawn in from an interior space of the housing of the suction device and is led past the at least one component of the suction device. It is thereby possible to provide a cooling duct that has a particularly short loss distance, over which the cooling air can be led past the at least one component of the suction device with a minimum loss of cooling capacity. In this way, particularly effective cooling of the at least one component of the suction device can be brought about. A method for operating such a suction device is also provided, by which optimum cooling of the at least one component of the suction device can be made possible.
