SaM - Heat Convection • Thermal Resistance

Remeber:

==Heat Convection is defined by the motion of matter==. The formula for the thermal resistance when we talk about heat convection is:$R_{TH}=\frac{1}{h\cdot A}$Where:

• $A$ is the area.
• $h$ is the convective heat transfer coefficient, it is similar to the thermal conductivity but it does not depend on space, its unit of measure is: $\left[\frac{\text{W}}{\text{°K}}\right]$

• There is an error in the measurment units, it should be:
  • $[\dot{q}]=\frac{W}{m^2}$
  • $[h]=\frac{W}{m^2\cdot °K}$
