Device for measuring solar shortwave radiation energy and method of manufacture

Abstract

The application discloses a device for measuring solar short-wave radiation energy and a manufacturing method thereof. The device comprises a thermopile fixing device, a thin-film thermopile is mounted on the thermopile fixing device. The thin-film thermopile comprises a substrate and at least eight pairs of thermocouple wires which are connected in series with each other and are uniformly distributed around the same circle center and coiled into a disc shape in a divergent manner. Each thermocouple wire is formed by carrying out vacuum copper plating on a polyester film through a first mask plate under vacuum; the polyester film is attached to the substrate; a black coating is arranged on the surface of a hot junction of each thin-film thermopile, so that various appearance designs and weight control are conveniently carried out according to the thin-film thermopiles, the response of a cold end and a hot end is fast; the total radiometer output time from one steady-state signal to another steady-state signal is shorter when the sunlight step changes, so that the zero offset is reduced; as a detection element which is non-selective to a spectrum, the device is stable in performance, short in response time, wide in spectral response range and good in structural firmness.

Description

technical field [0001] The present application relates to the field of measurement technology, in particular to a device and manufacturing method for measuring solar short-wave radiation energy. Background technique [0002] The sun is a huge blazing sphere of gas with a surface temperature of about 6,000 degrees and an internal temperature of more than 20,000 degrees. The sun constantly emits huge energy to the surrounding space, which is called solar radiation energy, or solar radiation for short. Solar radiation is the main source of energy on the earth, and it is the basic driving force for various physical processes and various life activities in the atmosphere, hydrosphere, and upper layers of land. The purpose of meteorological solar radiation observation is to obtain solar and earth radiation data, which is of great significance to industries such as agriculture, national defense, biology, ecological environment, meteorological science, climate prediction, and solar...

Problems solved by technology

[0003] This application proposes a device and manufacturing method for measuring solar short-wave radiation energy, which aims to solve the problem that the core device winding base of the prior art pyranometer has a large volume, which affects the miniaturization and lightweight performance of the product. In addition, the response time is slow, the zero point offset is large, the non-linearity is poor during long-term measurement, and the measurement accuracy is poor, which cannot meet the current demand for higher measurement of sunlight resources.
