The invention discloses a black body cavity structure based on a high-temperature black body radiation source, and relates to the technical field of calibration equipment. The black body cavity structure comprises a shell. A black body cavity extending into the shell penetrates through one end of the shell. An isothermal block used for being inserted into a standard platinum resistance thermometer is arranged in the black body cavity. A mounting sleeve matched with the black body cavity is fixed into the end, penetrating through the black body cavity, of the shell. A heat insulation box with the inner wall fixedly connected with the bottom of the mounting sleeve is fixed to the inner wall of the shell. According to the invention, by arranging a structure matched with the black body cavity for use, high-temperature air in the black body cavity is mixed and then flows back into the black body cavity, so that the high-temperature environment temperature in the black body cavity is uniform, the emissivity is improved, and the accuracy and reliability of the black body radiation source for verification or calibration are ensured.
Description
technical field [0001] The invention belongs to the technical field of calibration equipment, in particular to a blackbody cavity structure based on a high-temperature blackbody radiation source. Background technique [0002] At present, the measurement calibration and graduation of infrared thermometers mainly use blackbody furnaces. The so-called blackbody furnace is generally a furnace that uses three-stage windings for heating and temperature control, and a blackbody cavity is built into the furnace. Due to the limitation of structure and temperature control technology, the temperature uniformity and large temperature fluctuation in the black body cavity are poor, especially in the case of high temperature, due to the high internal temperature, when there is local temperature unevenness, The emissivity of the black body cavity is low, and it is difficult to be detected, which limits the improvement of the measurement calibration and graduation accuracy of the infrared t...
