Hi,
I shall be grateful if someone can help with this fundamental understanding,
Thermal resistance (in case of conduction mode of heat tarnsfer) can be defined as;
Rt = L / kA
where k is the thermal conductivity
Thus.
thermal resistance if inversely proportional to the thermal conductivity..
Low thermal conductivity means high thermal resistance
My question is;
1) What is good? To have high thermal resistance or low thermal resistance?
2) High thermal resistance would result less heat transferred per unit area. Right?
3) So, am I right in saying that whether you need high thermal resistance or low thermal resistance is problem dependent?
Sorry for being too basic.
