1 Product overview

1.1 Overview

The ZT 0007 radiant energy transfer test bench is a training and teaching device used by the laboratory to verify the changes in radiant energy transfer. The experimental bench contains two radiation sources: a radiator and a light emitter (radiation power can be adjusted). The thermal radiation is detected by a thermopile, and the optical radiation is recorded by a photometer. Various optical elements are mounted on the optical bench between the emitter and the detector, and the distance between each optical element can be read from the ruler along the optical platform. You can rotate the illuminance meter to study how the angle of incidence affects the radiation intensity. The matching optical components are used to study the reflection, absorption and transmission of different materials at different wavelengths and temperatures. Experiments can verify Kirchhoff's radiation law, Stefan-Boltzmann's law, Lambert distance and direction law and other basic heat transfer laws. The measured value is directly displayed on the measuring amplifier in digital form, or it can be directly transmitted to the PC section through USB for further processing.

2.1 Thermal radiation and radiation heat transfer

2.1.1 Concept of heat radiation

Thermal radiation is a phenomenon in which an object radiates electromagnetic waves due to its temperature. One of the 3 ways of heat transfer. All objects with a temperature higher than absolute zero can produce heat radiation. The higher the temperature, the greater the total energy radiated and the more short-wave components. The spectrum of thermal radiation is a continuum, and the wavelength range can theoretically range from 0 to ∞. Generally, thermal radiation mainly relies on longer-wavelength visible light and infrared rays to propagate. Since the propagation of electromagnetic waves requires any medium, thermal radiation is the only heat transfer method in vacuum.

The electromagnetic wave of thermal radiation is excited when the thermal motion state of the microscopic particles inside the object changes. As long as the temperature of the object is higher than zero degrees, the object will always convert heat energy into radiant energy and emit radiation outwards. At the same time, the object will also continue to absorb the heat radiation projected by the surrounding objects onto its surface, and regenerate the radiant energy. Converted into heat. Radiative heat transfer refers to the total effect of mutual radiation and absorption of objects. When the object is in thermal equilibrium with the environment, the heat radiation on its surface is still going on, but its net radiative heat transfer is zero.
