Heat input calculation
Web22 dec. 2024 · The power loss of a power converter is 17W, and the maximum temperature is limited to 110℃. Find the maximum operating ambient temperature after installing the heat sink. The specifications of the heat sink and thermal pad are defined as follows: Heatsink thermal resistance=3.2 W/℃. Thermal pad conductivity=1.56 W/m℃. Web11 feb. 2024 · Plucky. May 12, 2010. #3. Heat input is how much energy you put into the boiler to get its output. So due to efficiency losses you might find a boiler with a 20kw output has a heat input of say 22kw. If you have sized a house and need 20kw you would be looking for a boiler with an OUTPUT of 20kw. Most boiler manufacturers quote outputs.
