A blackbody radiation device for simulating meteorological environment

Abstract

The invention discloses a blackbody radiation device for simulating meteorological environment, which comprises a blackbody body, a heat bearing unit, several temperature control units and a temperature detection unit. Among them, the outer surface of the blackbody body is arranged as an arc surface; the heat bearing unit is set on the outside of the blackbody body in the form of a shell cover, and a thermal fluid circulates in the heat bearing unit to conduct basic heat to the side of the blackbody body; several temperature control units are arranged in Between the blackbody body and the heat bearing unit, one end of any temperature control unit is connected to the heat bearing unit and receives the basic heat from the side of the heat bearing unit, and the other end is connected to the blackbody body, and is sent to the blackbody through the temperature control action of the temperature control unit. One side of the body outputs temperature control heat; the temperature detection unit is sandwiched between the temperature control unit and the blackbody body, and connected to the temperature control unit, and the temperature detection unit is used to detect the temperature control heat. Ensure the controllability of temperature adjustment, so as to effectively adapt to the performance evaluation and calibration of long-wave radiation sensors and thermal imaging atmospheric radiation sensors.

Problems solved by technology

[0007] Therefore, the technical problem to be solved by the present invention is that none of the black body radiation devices in the prior art can meet the needs of operators to simulate the real meteorological environment, such as random changes to clouds or changes in temperature or atmospheric environment with zenith angles. Impact on radiation, etc., can not really realize the defects of atmospheric radiation experiments or scientific research
