Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Compact computer systems with multiple shielding casings face challenges in cooling heat-generating components due to their tightly enclosed nature, which complicates thermal management.
Innovation Solution
A housing assembly with strategically placed ventilation openings in two shielding casings, where one casing has a recess to create a pressure chamber, allowing for airflow to cool components across both casings using a single fan, enabling efficient passive and active cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If multiple shielding casings are used to enclose individual components, then electromagnetic interference is avoided and compact construction is achieved, but cooling of heat-generating components becomes complicated
Solution Approach 1:
The patent combines multiple cooling functions into a single fan by creating a shared cooling air channel that serves both shielding casings. The cooling air channel is formed by the recess in the housing wall, allowing one fan to cool components in both the first and second shielding casings simultaneously, thus reducing the number of fans and simplifying the cooling system.
Solution Approach 2:
The cooling air channel acts as an intermediary structure that connects the two shielding casings thermally. It allows cooling air to flow from the first shielding casing through the recess-formed channel to the second shielding casing, enabling efficient heat removal from both enclosures without requiring separate cooling systems.
2Reliability
If shielding casings are tightly enclosed to protect components, then component protection is improved, but airflow for cooling is restricted
Solution Approach 1:
The housing wall is segmented by creating a recess that forms a dedicated cooling air channel. This segmentation allows the shielding casings to remain tightly enclosed for protection while providing a specific pathway for cooling airflow to pass through, thus maintaining both protection and cooling efficiency.
3Productivity
If multiple fans are used to cool components in separate shielding casings, then cooling coverage is improved, but device complexity and cost increase
Solution Approach 1:
The patent merges the cooling functions for both shielding casings into a single fan system. The recess in the housing wall creates a shared cooling air channel that allows one fan to serve multiple components in different enclosures, reducing the total number of fans required while maintaining adequate cooling coverage.
