Heat flux density: The heat flow rate per unit area perpendicular to the direction of heat flux. q=dQ/dA(W/m2)。 Portable heat flow meter HFM-201: A thermal instrument composed of a heat flow sensor (or heat flow probe) connected to a measuring finger instrument. When in use, burying the sensor inside the insulation structure or attaching it to the outer surface of the heat transfer structure can directly measure the heat (cold) loss value. Heat flux transducer (HFT): a device that measures the heat flux density passing through a board with a determined thermal resistance by generating a temperature difference on the board. The output potential (V) is proportional to the heat flux density (q) passing through the sensor. It consists of a core board, a surface temperature difference detector, and a panel that provides protection and thermal damping.
