The new evacuated heat-pipe tube is a revolutionary breakthrough in solar thermaltechnology as well as the symbol of a great leap in solar thermal utilization fieldafter mankind's continuous researches year after year. The tube has the followingadvantages: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 sand2) It prevents the tube from being easily broken caused by the volume expansion when the water in tube freezes in frigid season3) 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℃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 winter5) Solar collecting plate is installed and sealed inside the tube of high-
