Problems solved by technology

[0007] The tower system is a thermal fluid conversion device that uses a solar mirror as a heliostat to focus multiple solar reflectors on a thermal fluid conversion device. The utilization time is only 4-6 hours. For example, the solar mirror on the east side of the tower is basically unusable in the morning, and can only be used after noon or afternoon, so the efficiency of solar energy collection is low. This technical solution can realize high-temperature collection, but Usually its size is large, not suitable for small or home systems
