High Efficiency Tile Roof Vacuum Tube U Pipe Solar Collector Black Aluminium Alloy Frame
Three-high Solar collector tube
1. advance technology.
2. solar vacuum tube
3. high efficient.
Evacuated tubes convert solar energy into heat energy, that is transferred to U pipe by an aluminum fin with high solar energy absorption and low heat radiance loss, Liquid (antifreezing liquid or water) in the U pipe heats up, and the U pipe conducts thermal energy to the water inside the storage tank directly (or through internal copper coil), With a testing pressure of 1.2 MPa, Working pressure is 0.6MPa.
Specification of three-high all-glass vacuum heat collection tube:
Structure: All-glass double-tube co-axial structure;

3. Internal pipe diameter and thickness:
Φ=37±0.7mm &=1.6mm;Φ=47±0.7mm &=1.6mm;Φ=58±0.7mm &=2.0mm.
4. Pipe length:
5. Absorptive coating property:
Deposition Method: 3 high magnetron sputtering plating.
Absorption than: As=0.93~0.96(AM1.5).
Emission ratio: 0.04~0.06(80±5).
6. Vacuum tightness:
7. Idle sunning property parameters:
Y=260~300m2 . /KW.
8. Solar irradiation for obtaining a preset water temperature:
H≤4.7MJ/m2 (Φ58) H=3.7~4.2 MJ/m2
H≤3.7MJ/m2 (Φ47) H=2.9~3.2 MJ/m2
9. Average heat loss coefficient:
In each vacuum tube there is a U pipe with direct flow-through that is connected to the header pipe inside manifold.
This U pipe is seamed in an aluminum heat transfer fin in the interior of vacuum tube that transmits the heat from the interior tube to the U pipe.
Solar radiation permeates the outer glass tube and is captured on the outside of inner glass tube by highly selective sputter layer.
The captured solar radiation is transmitted to flush-contact aluminum shield and then copper pipe filled with heat transfer fluid.
The 360° Aluminum heat transfer fin assures the fastest energy transfer.
