 2016 Pressurized Heat Pipe Solar Water Heater 


Product Description

Working principle of compact pressurized solar water heater

-Solar energy is absorbed and converted into heat energy by the absorption layer of vacuum tubes

-Heat energy is dilivered to heat pipe through aluminum wings.

-Working liquid in heat pipe absorbs heat and vapors,it moves towards condenser and releases the latent heat of vaporization .

-As condenser indirectly contacts with water through a copper cap,the heat is passed through it to the water in tank.

-At the end,cold liquid returns to the bottom of heat pipe and repeats the cycle.

Features of  pressurized system

-Instant startup(low startup temperature)

-Without water in vacuum tube,it won’t freeze in cold weather 

-Without water in vacuum tube,it wont scale and always keep high heat change efficiency

-Without water in vacuum tube,it keeps work with one single tube break down

-Withstands water pressure 1.2MPa (Testing pressure) and directly connects with city water,automatic operation, there is no need to feed the water by hand
