Feature: 1. Using a high efficiency heat pipe and heat transfer fin design to conduct the heat from within the all glass vacuum tube up to the header; 2. Due to the vacuum between the two glass tubes, conductive and convective heat loss are eliminated; 3. The tube is 100% glass, the problem with loss of vacuum due to a broken seal is greatly minimized, therefore, these tubes perform very well in overcast conditions as well as low temperatures; 4. The evacuated heat pipes used in Lotusino solar[...]
