Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a condenser is used to condense vaporized cooling medium into liquid cooling medium, then the cooling medium can be recycled for heat dissipation, but the condenser needs to work in negative pressure state which increases processing difficulty and size
Solution Approach 1:
The patent divides the condensation process into two separate heat exchangers: a first heat exchanger that condenses gaseous cooling medium into liquid at normal pressure, and a second heat exchanger that further cools the liquid cooling medium. This segmentation eliminates the need for the condenser to operate in negative pressure state, thereby reducing processing difficulty while maintaining cooling medium recycling efficiency.
Solution Approach 2:
The patent introduces a second heat exchanger as an intermediary component between the first heat exchanger and the delivery pump. The second heat exchanger further cools the liquid cooling medium produced by the first heat exchanger, enabling the system to achieve the required cooling effect without requiring the condenser to operate in negative pressure state.
2Productivity
If the size of the condenser is increased to improve condensation capacity, then more vaporized cooling medium can be condensed, but the processing difficulty and cost increase correspondingly
Solution Approach 1:
The patent segments the condensation and cooling functions into two separate heat exchangers. The first heat exchanger handles condensation at normal pressure with simpler construction, while the second heat exchanger handles further cooling of the liquid cooling medium. This segmentation allows each component to be smaller and easier to manufacture while collectively providing the required condensation capacity.
Solution Approach 2:
The patent changes the pressure parameter from negative pressure to normal pressure in the first heat exchanger, simplifying the construction and manufacturing requirements. The second heat exchanger then handles the temperature reduction of the liquid cooling medium. This parameter change enables the system to achieve the required condensation capacity with easier-to-manufacture components.
3Reliability
If negative pressure design is applied to the condenser, then condensation of vaporized cooling medium is achieved, but sealing requirements and structural strength requirements increase
Solution Approach 1:
The patent segments the cooling process into two stages: condensation at normal pressure in the first heat exchanger, and further cooling of the liquid cooling medium in the second heat exchanger. This segmentation eliminates the need for negative pressure design, thereby reducing sealing and structural strength requirements while maintaining reliable condensation function.
Solution Approach 2:
The second heat exchanger acts as an intermediary that further cools the liquid cooling medium produced by the first heat exchanger. This intermediary component enables the system to achieve the required cooling effect without requiring negative pressure design, thereby reducing sealing and structural strength requirements.
