A heat collecting tube including a cavity in a heat collecting device having a reflector, a method of manufacturing the same, and a reflecting device for applying reflected light to the cavity

摘要

In the solar collector with reflector, most of the reflected light acts in the community of the collector tube and prevents light leakage to significantly improve the heat collection efficiency. It also applies a low-cost manufacturing method and applies high efficiency solar collector to home and industry. The invention is practical and low invention as a heat source production equipment.;In addition, it is an invention for an easy-to-use heat collecting tube, a manufacturing method, and a dedicated reflecting device for improving the total energy change efficiency that simultaneously generates heat and photovoltaic power when a part of the reflector is applied to a solar cell having a cooling facility.
