Thermal Resistance Flashcards
1
Q
What is thermal resistance?
A
Thermal resistance (Rτ) is the resistance component in the thermal equivalent of V=IR, where ΔT=(dQ/dt /A) * Rτ
2
Q
How do you calculate thermal resistance at a boundary?
A
Rτ=1/h
3
Q
How do you calculate thermal resistance through a substance?
A
Rτ=1/λx
4
Q
What is λ?
A
Thermal conductivity
5
Q
What is h?
A
h is the heat transfer coefficient
