Problems solved by technology

[0004] The tower system is a heat pipe utilization device that uses a solar mirror as a heliostat and focuses multiple solar reflectors on a heat pipe utilization device. Due to the characteristics of tower solar energy collection, it makes the use of part of the solar mirror in the tracking solar process The 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 achieve high temperature collection, but usually other Large scale, not suitable for small or home systems
[0005] The present inventor has announced the zoom tracking system of two structures of cross type and disc type in 2006100203529 solar optical mirror tracking utilization device and its array, but this structure should belong to the combination of one or a group of solar mirrors and a heat pipe utilization system, and at the same time It is still limited to the two structures of the cross type and the disc type and cannot meet more needs
