Main Components Of Solar Water Heater

- Nov 05, 2019-

Solar water heater is mainly composed of collector, water tank and bracket.


1. Water tank shell


Generally, the water tank is made of color coated steel plate or galvanized steel plate, and the shell of some luxury solar water heaters is made of imported SUS304 stainless steel.


2. insulation layer


The thermal insulation material of the thermal insulation layer adopts the imported polyurethane high-pressure, high-density overall mechanical foaming, constant temperature heating material. This kind of heat preservation material has the advantages of small and uniform bubbles, reasonable density, high closure rate and good heat preservation effect.


3. Tank


Generally, the tank is made of 0.5mm imported high-quality SUS304 food grade stainless steel, with high-frequency welding technology, which can ensure long-term use without rust and water leakage.


4. seal ring


The sealing ring is made of high-quality silicone rubber with good sealing performance, and its service life is more than twice that of ordinary silica gel.


5. Water tank end cover


The end cover of the water tank is made of 1.0mm aluminum alloy by one-time casting and pressing, with anti-counterfeiting raised hinge, internal lock catch, no rust and good coordination with the water tank.


6. collector


The collector adopts high efficiency vacuum heat collector. The specification of vacuum tube is 1200-1500mm, and its absorption rate is more than 90% of infrared emissivity. At present, the best vacuum tube is al-nal vacuum sputtering selective coating tube.
