Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If water-cool type cooling cabinet uses high voltage alternating current for cooling components, then cooling efficiency is improved, but risk of electrical damage and shock increases
Solution Approach 1:
The patent divides the power system into two separate sections: a high-voltage AC power supply section for the cooling pump and a low-voltage DC section for internal electronic components. This segmentation isolates the high-voltage hazard to a specific area while maintaining efficient cooling through AC-powered pumps, thereby resolving the contradiction between cooling efficiency and safety.
Solution Approach 2:
The patent introduces a power distribution board as an intermediary component that manages power distribution. It includes isolated power supply circuits and protective devices that act as mediators between the high-voltage AC input and the low-voltage DC internal components, preventing direct exposure to high voltage while maintaining cooling functionality.
2Power
If water-cool type cooling cabinet uses high voltage alternating current, then power delivery capability is improved, but safety against leakage damage deteriorates
Solution Approach 1:
The patent segments the electrical system into high-voltage AC and low-voltage DC zones with physical and electrical isolation. The cooling pump receives high-voltage AC power for adequate power delivery, while internal components operate on isolated low-voltage DC, preventing hazardous leakage damage to electronics and improving overall reliability.
Solution Approach 2:
The patent incorporates protective measures in advance, including isolated power supply circuits, fuses, and circuit breakers between the high-voltage AC input and internal components. These protective devices act as beforehand cushioning against potential electrical leakage or failure, protecting the system while maintaining high power delivery capability for cooling.
