ABSTRACT:
A heat-flux gage, a manufacturing method and a manufacturing device thereof which are improved from circular foil heat-flux gage disposed in ASTM E511 comprise: a cylindrical body having a receiving space therein, and a foil mounting hole on one end thereof; a foil including a heat absorption surface, an inner surface facing the heat absorption surface, and a radiant side surface connecting the heat absorption surface and the inner surface, wherein the inner surface faces toward the receiving space and the radiant side surface is contacted to a side surface of the foil mounting hole; a foil lead wire connected on a center of the inner surface of the foil; a body lead wire connected to an opposite end of the foil mounting hole on the cylindrical body; and a filler filled in the inner receiving space, to prevent the foil lead wire from being damaged by fixing the foil lead wire.
