Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If liquid-cooling or air-cooling methods are used for the magnetic core assembly, then heat dissipation can be achieved, but the system complexity increases and reliability decreases due to corrosion risks
Solution Approach 1:
The patent extracts the cooling function from the magnetic core assembly by providing a separate housing with heat-dissipating teeth that extends outward from the assembly. This separates the heat-generating component from the heat-dissipating structure, allowing the magnetic core assembly to be fully sealed while maintaining effective heat dissipation through the housing's extended teeth.
Solution Approach 2:
The patent transitions from conventional planar heat dissipation to three-dimensional heat dissipation by providing heat-dissipating teeth that extend outward from the housing in multiple directions. This dimensional expansion increases the heat dissipation surface area without increasing the footprint of the magnetic core assembly, enabling efficient heat dissipation while maintaining a compact, sealed structure.
2Reliability
If the magnetic core assembly is fully sealed for high protection grade, then corrosion resistance improves, but heat dissipation capability deteriorates
Solution Approach 1:
The patent introduces the housing as an intermediary structure between the sealed magnetic core assembly and the external environment. The housing acts as a thermal mediator that conducts heat away from the sealed assembly through its heat-dissipating teeth, allowing the assembly to remain fully sealed for corrosion protection while the housing handles the heat dissipation function.
Solution Approach 2:
The heat-dissipating teeth create a porous-like thermal pathway structure that allows heat to escape from the sealed assembly through multiple distributed channels in the housing. This distributed thermal pathway system maintains the sealed integrity of the assembly while providing efficient heat dissipation through the housing's tooth structure.
