Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the magnetic element and heat radiator are disposed in parallel with the electronic device inside a box, then the structure is compact, but the magnetic element blocks the cold air blast and reduces the radiation effect of the heat radiator
Solution Approach 1:
The inverter is divided into two separate boxes: a first box for the electronic device and a second box for the magnetic element and heat radiator. This segmentation isolates the heat-generating magnetic element from the electronic device, preventing heat accumulation while maintaining structural integration through shared mounting plates and coordinated ventilation design.
Solution Approach 2:
The magnetic element is extracted from the first box and placed in a separate second box. This extraction removes the heat source from proximity to the electronic device, eliminating the blocking effect on cold air blast and allowing the heat radiator to function independently without interference from the magnetic element.
2Temperature
If the heat radiator is disposed outside the box, then heat radiation is improved, but most heat generated by the magnetic element is accumulated inside the box and damages the electronic device
Solution Approach 1:
The inverter structure is segmented into two boxes with distinct thermal zones. The first box houses the electronic device in a thermally controlled environment, while the second box contains the magnetic element and heat radiator for external heat dissipation. This segmentation prevents heat accumulation in the electronic device compartment while maintaining effective heat radiation.
Solution Approach 2:
The mounting plate acts as an intermediary thermal barrier between the heat-generating magnetic element and the electronic device. It provides mechanical support while thermally isolating the two components, preventing heat transfer to the electronic device while allowing the heat radiator to dissipate heat effectively.
3Temperature
If the cooling fan blows both the magnetic element and heat radiator, then heat dissipation is enhanced, but the magnetic element blocks the airflow and reduces radiation effect
Solution Approach 1:
The cooling system is segmented into separate airflow zones for the electronic device and the magnetic element/heat radiator. The cooling fan in the second box generates cold air that flows through the heat radiator first, then passes over the magnetic element, creating an unobstructed airflow path that enhances heat dissipation without blocking effects.
Solution Approach 2:
The airflow path is optimized by positioning the heat radiator and magnetic element at different spatial locations within the second box. The cold air flows horizontally through the heat radiator fins, then continues to the magnetic element, utilizing three-dimensional space to create an unobstructed flow path that maximizes heat dissipation efficiency.

AI summary
An inverter is provided according to the disclosure. In the inverter, an electronic device is disposed inside a first box; a heat radiator and a cooling fan are disposed inside a second box; and a magnetic element is disposed outside the first box and the second box. In this way, the cooling effect on the electronic device inside the first box and the heat radiator inside the second box may be less affected by the heat generated by the magnetic element. The magnetic element being disposed outside the first box and the second box is also beneficial to heat radiation of the magnetic element. The cooling fan only blows the heat radiator for heat radiation, there is not a case that the magnetic element blocks the cold air blast flowed through the heat radiator as in the conventional technology, therefore a more unobstructed air duct is formed, and the radiation effect is improved.
