Adiabatic calorimeter

摘要

Adiabatic calorimeter, consisting of a calorimeter vessel with a heater (14) and three adiabatic shells (2, 3, 4) which enclose the calorimeter vessel and are provided with heaters (14) and thermoelectric converters (12), with the adiabatic calorimeter being the thermoelectric The transducer (12) together with the heater (14) of the calorimeter vessel are connected to a temperature measuring and control device (9), characterized in that the dishes (2, 3, 4) and the calorimeter vessel are made of highly thermally conductive material, that the heaters (14) of the shells (2, 3, 4) are arranged on the outer surfaces of the shells (2, 3, 4), that the thermoelectric converters of the shells (2, 3, 4) are arranged on the inner surfaces of the shells (2, 3, 4) so that the calorimeter vessel is equipped with three thermoelectric converters (12) built into it, two of which a n the edges of the calorimeter vessel are diametrically opposite each other and the third is in the middle of the calorimeter vessel, that the heater (14) of the calorimeter vessel is evenly distributed around the circumference of the vessel, that the calorimeter vessel in the form of a disc drum with a lid (17) and a Bottom (16) is designed so that the drum (1) is symmetrical with respect to the vertical imaginary axis of rotation and has the same cylindrical through bores (11) with a predetermined diameter, and that the number of through bores (11) is determined on the basis of the prerequisite is that the total area occupied by the through bores (11) on the drum is the maximum possible.
