FIELD OF TECHNOLOGY

[0001] The present invention relates to the technical field of solar heat collection, and in particular to a cellular phase change energy storage solar heat-collecting device.

BACKGROUND

[0002] A solar heat collector is a core part of a solar heat utilization system.

The solar heat collector absorbs light radiated by the sun, generates great heat energy, and provides continuous power. Different water heating systems use different solar heat collectors. Heat collectors are divided into low-temperature, medium-temperature and high-temperature types according to different temperatures. The solar heat collector belongs to the low-temperature type. Of course, different standards have different classifications. Heat collectors may be divided into a tracking heat collector and a non-tracking heat collector according to whether the heat collectors move around the sun all day. In our life, the most common solar heat collectors are flat-plate solar heat collectors and vacuum-tube solar heat collectors.
