Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional cooling channels are used, then the structure is simple, but the cooling efficiency is insufficient due to low air velocity
Solution Approach 1:
The cooling channel structure is modified by changing geometric parameters - specifically creating a velocity increasing section where the cross-sectional area decreases in the flow direction. This parameter change transforms the cooling channel from a simple uniform structure to one with varying cross-section, thereby increasing air velocity and cooling efficiency without adding complex external systems
Solution Approach 2:
The invention introduces a new dimensional characteristic to the cooling channel by incorporating a velocity increasing section with varying cross-sectional area along the flow direction. This dimensional change (from uniform to tapered geometry) enables the channel to accelerate cooling air, improving heat dissipation capability while maintaining structural integration
2Power
If high-power IT components are used, then functionality is improved, but heat generation increases causing heat-related failures
Solution Approach 1:
The invention converts the harmful effect of high power consumption (heat generation) into a beneficial outcome by designing a cooling channel that actively utilizes the temperature differential. The velocity increasing section accelerates cooling air flow, enhancing heat removal from high-power components and transforming the heat problem into an opportunity for improved cooling efficiency
Solution Approach 2:
The cooling channel with velocity increasing section acts as an intermediary between the heat-generating IT components and the cooling air. This intermediate structure facilitates efficient heat transfer by optimizing air flow velocity, thereby protecting high-power components from heat-related failures while maintaining their high functionality
3Temperature
If air velocity in cooling channel is low, then the structure is simple, but heat dissipation is insufficient
Solution Approach 1:
The cooling channel design is enhanced by changing the geometric parameter of cross-sectional area along the flow direction. The velocity increasing section features a gradual reduction in cross-sectional area, which naturally accelerates air flow velocity and improves heat dissipation capability without requiring external fans or complex flow control mechanisms
Solution Approach 2:
The cooling channel is segmented into distinct functional sections: an inlet section, a velocity increasing section with varying cross-sectional area, and an outlet section. This segmentation allows each portion to perform its specific function optimally, with the velocity increasing section specifically designed to accelerate air flow for enhanced heat dissipation
