Integrated Pressure PVDF Heat Pipe Solar Water Heater with galvanized steel frame working principle
1. The water storage tank is a closed pressure reservoir without any air-vent, hence the outlet hot water shares the same pressure with the inlet cold water.
2. Heat pipe heads are plugged into the pipe caps which are fixed in a row in storage tank, the vacuum tubes absorbs solar irradiation with its coating and transfer to heat pipe tubes through aluminum fins, the heat-conduction liquid inside heat pipe tube will vaporize and rise to heat pipe head to release heat to water inside storage tank through the pipe caps, then the vapor will condense to form liquid and flows down to heat pipe bottom and wait for second heat transfer.
Description
1) Inner tank material: SUS304-2B stainless steel. Available thickness is 1.2-1.5mm.
2) Outer tank material: Silver fluorocarbon (PVDF) plate 0.4MM
3) Heat pipe Vacuum tube: 58x1800mm
Material: High borosilicate glass, three-layer coated vacuum tube.
Over 15 years service life. Hail resistance: 25mm.
4) Insulation layer: High density polyurethane foam, available thickness is 50-60mm.
5) Very popular tank capacity in present markets is 150-300L.
6) Frame material: Hot-dip black coated galvanized steel 1.2mm , universal bracket suitable for slope and flat roof installation
Applications:
Domestic hot water for shower, washing
Competitive Advantage:
1.Adopts the best conduction performance metal- heat pipe (copper)
2.Can be used all year round in the cold climate
3.High efficiency, rapid warming. Heat pipe in vacuum tube could transfer hot energy to cold water in pressurized solar water heater tank rapidly
4.The whole pressure of the system is up to 1.5kg/M2, the inlet could connect the tap water directly, the max pressure can be 0.6Mpa
5.No water in the tube, one tube broken don't influence the system working
6.The design for inner tank is reasonable and scientific, which could hold 100, 000 times fatigue test without any damage
7.Dual-purpose brackets for both flat and inclined roof
8.The system is pressurized,it keep a constant temperature of water in the tank, avoid the problem came from water level controller malfunction which could cause water flow out
