Working principle:
The metal sheet with selective coating in the vacuum glass pipe is taken as the heat absorption surface from the solar energy. The absorbed heated is transmitted to the working medium in the heat pipe via metal medium and completes heat exchange via the heat pipe.
Use features of the product:
The new evacuated heat-pipe tube is a revolutionary breakthrough in solar thermal technology as well as the symbol of a great leap in solar thermal utilization field after mankind’s continuous researches year after year. The tube has the following advantages
1. Heat-pipe conduction, no water inside, thus it is successfully prevented from the defects of tube block and low power output caused by water fouling and deposits of mud and sand.
2. It prevents the tube from being easily broken caused by the volume expansion when the water in tube freezes in frigid season.
3. Start up quickly. Energy inside the tube can be taken out within 2 minutes under sunshine. The stagnation temperature of the heat-pipe can reach 220 °C
4. High efficient selective absorptive coatings and vacuum heat insulation technology ensure the tube to get higher heat output in cloudy weather and in moist area, especially in winter.
Applied fields:
It is widely used in large-sized hot water project/sea water desalination/Industrial heating/heating system and other fields
