one vacuum tube solar collector application1

Evacuated tube solar collectors (also called vacuum tube solar collectors) are higher efficiency solar collector, simpler installation and lower cost than traditional flat plate solar collector. It is widely used in solar central hot water engineering system, and they are the central part of Solar Water Heater, they convert sun energy into thermal heat via the vacuum tubes. 

SolarShine’s Evacuated tube solar collector are Φ 58 * 1800 high efficiency collector vacuum tubes with all- glass double- tube co- axial structure.

How the vacuum tubes work? 

The solar radiation passes through the outer tube of the vacuum tube and is absorbed by the heat collection coating, to heat the cold water in the vacuum tube. Due to the physical characteristics of water, the density of hot water is lower than cold water, and the water will "move" in the vacuum tube. The cold water will slowly come in, and the hot water will slowly go out and enter the insulation barrel. 

With the extension of radiation time, the heat will increase, the water temperature will rise, and there will be more and more hot water.

With the continuous upward movement of hot water and stored in the solar hot water tank, the water with lower temperature is continuously supplemented along the other side of the pipe. In this cycle, the whole tank of water finally rises to a certain temperature.
