WebOct 19, 2024 · To fabricate a thermally stable PCB, thermal effects must be studied during the designing phase itself. The first step in thermal design is to identify the hotspots. Thermal modeling or thermal simulation techniques are used to find hotspots. ... Designers can use a combination of some or all of the above heat transfer techniques and … WebThe heat-transfer effects follow directly from the magnetic effects and so only apply to electrically conducting coolants. If turbulence is suppressed then there is no mixing of the liquid layers and no convective heat transfer. Heat flow into the coolant is entirely by thermal conduction, and the Nusselt number will be constant, the value of ...
