Abstract

A computational procedure is developed for the thermal regime of anisotropic-thermoelement thermal converters of cavity and plane types used to investigate heat fluxes and energy parameters of radiation. Heat losses from different elements of the thermal-converter structure are analyzed and the parameters of a battery of anisotropic thermoelements are optimized, providing maximum sensitivity at minimum measurement errors. The results obtained were used in developing a fundamentally new cavity-type filter pyrheliometer and commercially produced automatic absolute radiometers.
