Abstract

[Problem] Thermal conductance of a heat source is grasped to contribute to the effective utilization of unused thermal energy.[Solution] A thermal conductance measuring method includes: connecting the other end of a thermal conduction path to a heat source to be measured, the thermal conduction path having a cooling source at one end (S10); installing a heating element in the thermal conduction path, the heating element controllable to fluctuate a heat generation amount by applying fluctuating heating energy to the heating element; measuring a temperature within the thermal conduction path and acquiring a first temperature affected by heat generation by the heating element and a second temperature not affected by heat generation by the heating element (S30, S50); and calculating thermal conductance of the heat source based on a difference between the first temperature and the second temperature (S60) and the heating energy when the first temperature was measured (S80). Since this allows the thermal conductance of the heat source to be calculated without the need to grasp a specific heat, mass, or the like of the heat source, it is possible to contribute to the effective utilization of the unused thermal energy possessed by the heat source.
