Description

technical field

[0001] The invention relates to a straight-through solar heat exchange and heat collection device using solar energy as a heat source, and belongs to the technical field of medium and high temperature solar heat utilization. Background technique

[0002] As we all know, most of the solar collector tubes widely used at present are double-layer glass tube structures with one end closed or straight-through glass inner tubes open at both ends. If double-layer glass tubes are used, the outer surface of the glass inner tube is coated There is a solar selective absorption coating, the working fluid is carried in the glass inner tube, and the vacuum is drawn between the glass inner tube and the glass outer tube. The heat collecting tube made in this way, when working, the temperature difference between the inner and outer tubes is large, and it is easy to cause tube explosion. In addition, the volume of the tube is too large, so it is not easy to heat.
