Heat pipe pressurized solar water heater
The principle of Heat Pipe Pressurized solar water heater Step 1: Evacuated tubes absorb sunlight and convert it to usable heat. Step 2: A vacuum between the two glass layers insulates against heat loss improvement efficiency. The heat transfer fin helps to transfer heat from the evacuated tube to the to the copper heat pipe. Step 3: The heat pipe contains a small amount liquid which forms steam when heated, rapidly transferring the heat up to the water in the storage.
