Background

The trough type heat collector is a heat collecting device which utilizes a photo-thermal conversion mode, realizes the conversion from light energy to heat energy through processes of focusing, reflecting, absorbing and the like, and enables a heat exchange medium to reach a certain temperature so as to meet the requirements of different loads. The trough type heat collector belongs to the category of medium-high temperature heat collectors, can enable a heat exchange working medium to obtain higher temperature, and can be used in life and production fields of thermal power generation, seawater desalination treatment, heating engineering, absorption refrigeration and the like.

The trough type heat collection system realizes the photo-thermal conversion process of the system by utilizing the solar radiation energy with high heat flux density collected by the trough type parabolic concentrating reflectors. Sunlight penetrates through the atmosphere and is incident on the earth surface, radiation energy with low heat flux density can be generated, the economy of the sunlight is influenced by direct utilization, and only the radiation energy with low heat flux density is converted into the radiation energy with high heat flux density through concentration. From the analysis of optical theory, the parabolic focusing is the only line type that can focus a beam of parallel light to a point. Thus, parabolic concentrating is one of the most common forms of concentrating, and solar trough collectors are one of them. The sunlight is incident on the surface of the earth and irradiates on a parabolic reflector additionally provided with a sun tracking device, at the moment, the sunlight can be incident on a groove type parabolic reflector at an angle approximately vertical to the paraboloid, the reflector collects the received sunlight to the surface of a heat collecting pipe, so that the heat collecting pipe receives solar radiation energy with high heat flux density, and the medium flowing in the pipe is heated through heat transfer with the medium in the pipe, thereby providing power for production and life. The main shaft for the condensing lens array of the existing trough type heat collector can only track the solar altitude angle, cannot track the solar azimuth angle and has low heat collecting efficiency.
