Trough solar collectors use parabolic concentrating principle to concentrate solar rays in the heat absorption tube at the focal position, and convert solar radiation energy into heat energy through the heat absorption tube, and then convert it into heat source for users in various ways.
Compared with ordinary solar engineering, trough concentrator converts low-density solar energy into high-density energy, and absorbs heat through heat transfer medium to convert solar energy into high-temperature heat energy.
1. Light aluminum alloy frame type trough type heat collector
The surface of the bracket of the trough collector is made of aluminum alloy, and the mirror reflection aluminum is used as the condenser lens, so the whole frame structure greatly reduces the weight of the collector per unit area. The condenser lens adopts honeycomb composite structure design, which not only utilizes the high-efficiency reflectivity of reflective aluminum, but also ensures the structural strength of the condenser. Modular production of all parts factory is easy to assemble, debug and maintain. This technology has passed SRCCTM (Solar Rating & Certification Corporation TM) testing and certification.
2. Glass mirror groove type heat collector
Glass mirror trough collector is a series of glass mirror products independently developed by Runh.
This series of products uses high-strength glass lenses as condenser lenses, and the main specification of this series of products is G2550.The glass mirror trough collector adopts super steel structure design, which has higher wind load resistance.
