A nondestructive method for measuring thermal parameters of hermetically sealed electron devices

摘要

The nonrestrictive method described is intended for measuring the quantity of heat coming from the surroundings into the working volume of the hermetically sealed device with a thermoelectric cooler. The method is based on the dependence of the thermal emf that appears across the thermopile leads of the thermoelectric cooler in the stationary operation mode on the thermal load on the heat-absorbing surface.
