Thermal simulation of toroidal coil

In current new product development, it has become essential to utilize thermal fluid simulation from the concept stage and create a design plan while visualizing the heat transfer path. Any simulation can produce some results if one learns the operation method. However, unless he/she properly models the parts after understanding the heat transfer phenomena and inputs the correct calorific value, he/she will get a wrong solution. Therefore, it is important to verify whether the simulation settings such as analysis method, shape modeling, and boundary conditions match the actual phenomena by comparing with the actual measurements. At the third subcommittee of the Chubu Electronics Association, in which Toyota Industries Corporation participates, the Nagoya Municipal Industrial Research Institute and companies are collaborating in a style of industry-government cooperation to conduct joint research on the theme of thermal design. They have been working on the theme of modeling parts in thermal fluid simulation in natural air cooling equipment. Among these efforts, this paper introduces the research results of thermal analysis modeling of toroidal coils. (A.O.)
