Casing Wall Segmentation for Thermal Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing housings for control devices with heat-generating components lack effective air throughput and cooling efficiency, particularly for electrical devices like converters, which can lead to inadequate thermal management and reduced performance.
Innovation Solution
The housing design features partially separated sections of the wall that are bent along specific lines, allowing for increased air flow and improved cooling by creating a targeted air flow path, with features like laser-cutting for burr-free edges and regular spacing of sub-areas to enhance air conduction properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the housing wall is made with continuous flat sections, then the manufacturing is simple, but the air throughput through the housing is insufficient
Solution Approach 1:
The housing wall is divided into multiple partial areas that are separated by interruptions. These segmented sections can be bent along bending lines to create protrusions or recesses, which increase the air throughput through the housing while maintaining manufacturing simplicity through standardized segmentation patterns.
Solution Approach 2:
The housing wall transitions from a flat two-dimensional surface to a three-dimensional structure by bending partial areas along bending lines. This creates protrusions or recesses that add depth and volume, increasing the effective air flow path and throughput without significantly complicating the manufacturing process.
2Temperature
If partial areas are bent to increase air throughput, then cooling efficiency improves, but the housing structure becomes more complex
Solution Approach 1:
The housing wall is segmented into partial areas that can be independently bent along specific bending lines. This segmentation allows for controlled structural complexity only where needed for cooling, while other areas remain simple and flat, balancing cooling efficiency with overall structural simplicity.
Solution Approach 2:
Only specific partial areas of the housing wall are bent to create protrusions or recesses, while other areas remain flat. This local modification approach increases cooling efficiency in critical regions without making the entire housing structure complex, maintaining simplicity where it is not needed for thermal management.
3Productivity
If interruptions are introduced into the housing wall, then air flow path is created, but the housing wall integrity is reduced
Solution Approach 1:
The housing wall is segmented into partial areas connected by bending lines rather than complete interruptions. This segmentation creates air flow paths through the bent sections while maintaining the continuous structural integrity of the housing wall, as the partial areas remain connected along the bending lines rather than being completely separated.
Solution Approach 2:
Instead of creating planar interruptions in the housing wall, the design uses three-dimensional bending of partial areas along bending lines. This dimensional transformation creates air flow paths through the bent protrusions or recesses while maintaining the wall's continuous structural connection, preserving housing integrity while enabling air flow.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design significantly improves air throughput and cooling efficiency, allowing for better thermal management of electrical devices, simplifies manufacturing, and enables more effective air flow adjustment and heat dissipation, particularly by deflecting heated air and creating a nozzle effect for enhanced ventilation.
Implementation Method 1
the air throughput is increased through the housing
Implementation Method 2
an air flow is sucked in from below and the air flow is guided through the housing from bottom to top, according to the thermals
Implementation Method 3
the interruption is introduced into the housing wall by means of laser cutting. The advantage here is that there are no burrs that would have to be reworked or that would create turbulence in the air flow through the housing

AI summary
A casing comprises at least one casing wall which is preferably realized in the form of a cover, back wall, front wall or in the form of one of two side walls. In the casing wall, one sub region or two or more subregions of the casing wall are partially separated from a remaining region of the casing wall by a respective interruption in the casing wall, said interruption at least partially encircling the subregion or the two or more subregions. The subregion or the two or more subregions is or are connected to the remaining region along a respective bending line. The subregion or the two or more subregions are bent over along the respective bending line in such a manner that the subregion protrudes out of the casing or projects into the casing or the two or more subregions protrude out of the casing or project into the casing.
