    Heating a large volume of air, heat energy vs power

    I want to heat a large volume of air in a well insulated box. I did some research but am unsure about how to calculate the time it would take as well as heat energy vs power. I want to raise the temperature from 20C-50C. Once it reached 50C, a PID will maintain the temperature with a damper...

    Internal air temp of an aluminum box with solar loading

    Hi all, I’ve seen a few other posts about this but many have internal power generation Lets say I have a large aluminum box, 10m x 10m x 10m that is completely sealed. If each side (except the bottom) if subjected to 500w/m^2 of solar loading. How much hotter will the internal air get? Is...

    Understanding the benefit of adding a vapor chamber to a heatsink

    I am currently researching heatsinks for IC cooling. I understand that a vapor chamber will help spread the heat out through the base of the device. But when considering the R-value of the system, doesnt adding a vapor chamber only increase the R-value of the system? I would understand removing...

    Thermal resistance vs thermal impedance

    I have been looking at a few properties that seem to be closely related, but I just cant figure out the finite differences. I understand that there is thermal conductivity in w/(m*k) where m is the distance the heat travels through. And that it is a property of a material. From there to get the...
