Medium and high temperature trough collector system
heat-bent glass focuses the sunlight on the metal through-tube heat-absorbing coating at the focus of the collector, and the heat is fully absorbed. At the same time, the collector keeps track of the Sun in real time under the action of the tracking system to keep the maximum heat absorption efficiency. The low-temperature working fluid flowing in the metal straight-through tube is heated, and the high-temperature working fluid and the energy-using terminal realize the heat energy conversion through the heat exchange, so as to achieve the goal of solar heat utilization
