Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetic elements are used in power electronic systems, then isolation and limitation of short circuit current, reactive power compensation and flat wave functions are achieved, but thermal dissipation becomes insufficient leading to overheating and potential malfunctions
Solution Approach 1:
A heat conduction pipe is introduced as an intermediary component between the magnetic column and external cooling medium. The heat conduction pipe rapidly conducts internal heat to external surfaces, serving as a thermal mediator that bridges the magnetic element and cooling air or liquid, thereby improving heat dissipation efficiency and reducing operating temperature
Solution Approach 2:
The patent utilizes external cooling air or liquid flowing through channels to remove heat from the magnetic element. The cooling medium carries away heat from external surfaces, implementing a pneumatic or hydraulic cooling system that effectively lowers the temperature of the magnetic element while maintaining reliability
2Temperature
If conventional cooling methods (liquid-cooling radiators or air-cooling radiators) are used, then external temperatures are reduced, but internal heat dissipation efficiency remains insufficient
Solution Approach 1:
The heat conduction pipe acts as a thermal intermediary that directly contacts the magnetic column interior and rapidly conducts heat to external surfaces. This intermediary structure overcomes the limitation of conventional cooling by creating an efficient heat transfer pathway from the heat-generating core to the cooling medium, significantly enhancing thermal dissipation productivity
Solution Approach 2:
The patent introduces an internal heat conduction dimension by placing the heat conduction pipe within the magnetic column. This adds a new thermal management dimension inside the magnetic element structure, enabling heat to be conducted from the interior along the pipe to external cooling surfaces, thereby improving overall heat dissipation efficiency beyond conventional external cooling methods
