What is heat flux?

Heat flux or thermal flux, sometimes also referred to as heat flux density, heat-flow density or heat flow rate intensity is a flow of energy per unit of area per unit of time. In SI its units are watts per square metre (W/m2). It has both a direction and a magnitude, and so it is a vector quantity.

How to Calculate Heat Flux?

Heat Flux calculator uses Heat Flux = Thermal Conductivity of Fin*Temperature of Conductor/Length of Conductor to calculate the Heat Flux, Heat flux or thermal flux, sometimes also referred to as heat flux density, heat-flow density or heat flow rate intensity is a flow of energy per unit of area per unit of time. Heat Flux is denoted by q symbol.
