Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional liquid-cooling heat dissipation mechanisms are installed in computer equipment with limited internal space, then heat dissipation function is achieved, but pipeline installation becomes complicated and occupies excessive space
Solution Approach 1:
The fin tubes are nested inside the reservoir, with the fin tubes having a U-shaped cross-section that fits within the reservoir's internal cavity. This nested configuration allows the heat dissipation fins to be contained within the reservoir structure, eliminating the need for external pipeline connections and reducing installation complexity while maintaining effective heat dissipation surface area
Solution Approach 2:
The reservoir and fin tubes are merged into a single integrated structure where the fin tubes are formed as an integral part of the reservoir body. The U-shaped fin tubes are positioned within the reservoir such that they share the same structural space, combining the fluid containment function and heat dissipation function into one unified component that simplifies installation and reduces space occupation
2Temperature
If conventional liquid-cooling heat dissipation mechanisms are installed in computer equipment with limited internal space, then heat dissipation function is achieved, but the occupied space of the piping system increases
Solution Approach 1:
The fin tubes are nested inside the reservoir, utilizing the internal cavity space of the reservoir for heat dissipation functions. This nested arrangement allows the heat dissipation surface to be positioned within the existing reservoir volume, eliminating the need for additional external space for pipeline installation and reducing the overall volume occupied by the cooling system
Solution Approach 2:
The fin tubes are oriented with their longitudinal axes extending in a direction perpendicular to the main elongation direction of the reservoir. This dimensional reorientation allows the heat dissipation surface to be developed in a different spatial dimension, efficiently utilizing the reservoir's internal volume without increasing the external footprint of the cooling system
3Temperature
If conventional pipeline design with inflow and outflow is used, then liquid cooling circulation is achieved, but connection with other pipelines becomes complex and water leakage risk increases
Solution Approach 1:
The external pipeline connections are extracted and eliminated from the design. Instead of requiring separate inflow and outflow pipelines to be connected to the reservoir, the fin tubes are configured to enable internal circulation within the reservoir structure, removing the vulnerable external connection points that could lead to water leakage
Solution Approach 2:
The reservoir with integrated fin tubes serves its own cooling function without requiring external pipeline connections. The U-shaped fin tubes positioned within the reservoir create an internal circulation path that allows the liquid cooling system to operate autonomously, eliminating dependency on external pipeline infrastructure and reducing leakage risks

Implementation Method 1
The liquid can flow in closed pipelines, and these closed pipelines are distributed on the surface of the electrical components... When liquid with relatively low temperature flows over the electrical components with relatively high temperature, the liquid absorbs heat energy
Implementation Method 2
Next, the heat energy of the liquid can be thermally exchanged by exterior or other heat dissipating mechanism through the closed pipeline for decreasing the temperature
Implementation Method 3
a first part of the fin tubes respectively communicates with the first chamber and the third chamber, a second part of the fin tubes respectively communicates with the third chamber and the second chamber, and a third part of the fin tubes respectively communicates with the second chamber and the fourth chamber
