Dummy Cover with Connection Opening for Electronic Apparatus Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic apparatuses with multiple slots, the presence of empty slots disrupts the pressure balance when dummy covers are installed, leading to reduced cooling efficiency for electronic component units due to uneven flow resistance and air supply.
Innovation Solution
The electronic apparatus incorporates a housing with accommodating portions, where a dummy cover with a connection opening is installed in empty slots to raise flow resistance and maintain pressure balance, ensuring consistent cooling air supply to units by connecting the inside and outside of the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If dummy covers are installed on empty slots to raise flow resistance, then pressure balance is improved, but cooling efficiency deteriorates due to disrupted pressure balance
Solution Approach 1:
The dummy cover is designed with a connection opening that provides a localized flow path. This allows different parts of the dummy cover to have different flow resistance characteristics - the cover body provides resistance while the connection opening allows controlled airflow, achieving both pressure balance and cooling efficiency simultaneously
Solution Approach 2:
The dummy cover changes the flow resistance parameter of empty slots by introducing a controlled connection opening. This modifies the airflow characteristics to maintain pressure balance while preventing complete flow blockage, thereby preserving cooling efficiency
2Stress or pressure
If dummy covers completely block empty slots, then flow resistance increases, but pressure balance is disrupted and cooling air supply decreases
Solution Approach 1:
The dummy cover implements local quality by having a cover body with a specific connection opening. This creates zones of different flow resistance - the cover material provides resistance while the opening allows airflow, achieving both increased overall resistance and maintained cooling air supply
Solution Approach 2:
The connection opening acts as an intermediary element between the dummy cover body and the external environment. It mediates the airflow by providing a controlled passage that increases flow resistance while still allowing cooling air to reach the electronic component units
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 configuration enhances the cooling properties of electronic component units by maintaining pressure balance and preventing a decrease in cooling air supply, thereby improving thermal management within the housing.
Implementation Method 1
the pressure balance in the housing is disrupted even in cases in which dummy covers are installed... If the pressure balance of cooling air in a housing is disrupted
Implementation Method 2
flow resistance due to the unit in the slot will cause the pressure of cooling air from the fan to increase
Implementation Method 3
The cooling air will tend to flow to areas with less resistance, i.e., to empty slots
