Many analogies exist relating heat flow to fluid flow. Oops, there’s one. A good electronics thermal design is one that gets the heat out from the heat sources quickly and the cold in to quench them quickly. Before I scoot off to sunny (though heavy rain is forecast) Devon for a family holiday I thought I’d leave you with this…
Thermal power dissipation is measured in Watts (W)
A Watt is a Joule/second (J/s)
A Joule is a Newton meter (Nm)
So Power = m/s x N
A speed multiplied by a force.
Does this mean that there is a concept of a (steady state) ‘speed of heat’? If so what is it? These aren’t rhetorical questions by the way 🙂
