A device for simulating concentrated solar light heating

Abstract

The invention discloses a simulated condensation solar illumination heating device belonging to the field of illumination heating equipment. The device comprises a strong light source array, a fiber array and a heating cavity, wherein a spherical xenon short-arc lamp is used as an artificial light source, a light output end of the fiber array is arranged on the heating cavity through an installation hole array on the heating cavity, the fiber array is used as a transmission medium and is used for guiding light to the heating cavity, and the heating cavity is used for fixing an emergent direction of light and is used as an output end of light heater; and since the fiber array has flexibility characteristic, the heating cavity for fixing a fiber can move and rotate within a certain range so as to be adaptive to heated workpieces at different directions and facing different directions. The surface of a heated object is uniform in illumination intensity, heating temperature rising direction is uniform, and the practicability and the flexibility of a strong light heating cavity device during the application process are improved; and meanwhile, a heating region is isolated with a light source region, the high-temperature resistant requirement of a high-temperature heating cavity is reduced, and the light source is high in safety.

Description

technical field [0001] The invention belongs to the field of illumination heating equipment, in particular to a simulated concentrated solar illumination heating device. Cavity lighting heating device. Background technique [0002] With the development of science and technology, the light heating system has become an important conventional heating method, which is used in various heating equipment. Among them, in order to realize the repeatable test under the high-intensity light required for indoor utilization of solar thermal energy, it is very necessary to simulate the concentrated solar heater. The core idea of ​​this type of technology is to use the concentrating arrangement of concentrating lenses or metal halide light sources to gather and collect the light from natural light sources or monochromatic light sources using the principle of geometric optics, and transmit them to objects that need to be heated. This light heating technology is characterized by simple str...

Problems solved by technology

The lighting and heating devices proposed in the current relevant patents are divided into two categories: the first category, such as the patent "solar network natural light lighting and heating device" (application number 2004100108078. The device that transmits light to the tubular heated body; the second type, such as the patented "illumination heating device" (application number 201320885177.5), is a direct heating device using a fixed or adjustable artificial metal halide light source array. The arrangement will converge the heating spots. The first type of device mainly uses the light source as the natural light source. The operation is limited by the weather conditions and the installation location of the equipment. The heating effect is unstable, and it is difficult to obtain fixed and repeatable lighting experimental conditions. Obtaining a higher heating temperature requires a larger floor area; the second type of device needs to fix the light heating light source on a bracket that cannot adjust the rotation direction, which limits the number of light sources installed and poses a higher requirement for the stability of the supporting structure. At the same time, the artificial light source is not isolated from the heating chamber. If the heating chamber is too high, it will pose a threat to the safety of the artificial light source.
