I have an application to heat an aluminium plate as heat sink - (thickness 1mm or 3 mm ) with surface area between 40, 000 mmp and 50, 000 mp to 40 Celsius degree - using Power resistor with an electric power of 100W, for instance
I found an article
https://www.digikey.com/en/articles...-in-power-resistors-and-the-use-of-heat-sinks
but does not help me to much and there are some differences related to sink calculator from link
https://www.allaboutcircuits.com/tools/heat-sink-calculator/
Also , mention the righr power supply for power resistor ( voltage, current)
