Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pumping device and heat dissipation device are externally connected to form a closed liquid circulation loop, then the liquid circulation function is achieved, but the device occupies large space and has poor installation flexibility
Solution Approach 1:
The patent merges the pumping device and heat dissipation device into a single integrated unit. The pumping device is embedded within the heat dissipation device, with the water pump base, shell, and impeller forming a compact assembly that is directly integrated into the heat dissipation structure. This eliminates the need for external connection pipes and separate mounting, thereby reducing space occupation and improving installation flexibility.
Solution Approach 2:
The patent applies nesting by placing the pumping device inside the heat dissipation device. The water pump base is embedded in the first water chamber, the water pump shell is positioned within the receiving cavity, and the impeller is received in the water pump water chamber. This nested arrangement allows the pumping function to be housed within the heat dissipation structure, significantly reducing the overall device footprint.
2Loss of energy
If the pumping device is externally connected to the heat dissipation device, then the liquid circulation loop is formed, but the circulation distance of liquid is long and power attenuation is high
Solution Approach 1:
By merging the pumping device and heat dissipation device into a single integrated unit, the liquid circulation path is dramatically shortened. The liquid flows directly from the heat dissipation structure through the embedded pumping device without requiring long external connection pipes, thereby reducing power attenuation and energy loss in the pumping process.
3Adaptability or versatility
If conventional water-cooled heat sinks are used, then heat dissipation function is achieved, but the design has high requirements for installation space and is inconvenient for installation and operation
Solution Approach 1:
The patent combines the pumping device and heat dissipation device into an integrated unit, creating a compact design that maintains effective heat dissipation functionality while significantly reducing the overall device size. This integrated design enables the device to adapt to conventional installation environments where space is limited, thereby expanding the application range and improving versatility.
