Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Chassis designs with horizontal plugged frames face inefficiencies in heat dissipation due to uneven air distribution and increased space requirements, which affect the normal operation of devices and cost-effectiveness.
Innovation Solution
A chassis design with an air inlet in the board area linked to a first air chamber, which distributes air evenly to the board area through a second air chamber and an air outlet, allowing for compact and cost-effective heat dissipation without expanding the chassis space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the air inlet is set on the top or at the bottom of the board area, then the air flow path is simplified, but the air volume is unevenly distributed to the board area, which reduces efficiency of heat dissipation
Solution Approach 1:
The air chamber is segmented into a first air chamber and a second air chamber. The first air chamber receives air from the air inlet and distributes it to the board area, while the second air chamber receives air from the board area and directs it to the air outlet. This segmentation enables even air distribution across the board area, improving heat dissipation efficiency without significantly increasing overall system complexity.
2Productivity
If two layers of fans are disposed, then the heat dissipation capability is enhanced, but the space of the chassis is enlarged, which reduces cost-effectiveness of heat dissipation
Solution Approach 1:
The patent transitions from a vertical stacking arrangement (two layers of fans) to a horizontal distribution arrangement (first and second air chambers positioned on opposite sides of the board area). This dimensional change allows the system to achieve enhanced heat dissipation capability through improved air distribution while maintaining a compact chassis footprint, thereby improving cost-effectiveness.
3Ease of manufacture
If a left-to-right or right-to-left air duct is designed, then system resistance is reduced and heat dissipation implementation is eased, but hot air may reflow and affect the normal running of the devices
Solution Approach 1:
The air flow path is segmented into distinct zones: the first air chamber for air distribution, the board area for heat dissipation, and the second air chamber for hot air collection. This segmentation prevents hot air reflow by creating separate flow zones, ensuring device operation stability while maintaining ease of manufacture through a straightforward air duct configuration.

Function Achieved in This Case
This design ensures even air distribution for enhanced heat dissipation efficiency and maintains a compact chassis structure, improving the cost-effectiveness of heat dissipation by eliminating the need for expanded space.
Implementation Method 1
air enters the first air chamber in the chassis with horizontal plugged frames through the air inlet that is located in the board area, and flows towards the board area after being sufficiently mixed in the first air chamber
