These patented tubes offer faster heating and lower heat loss since there is an exchange of steam instead of water. Using gaseous diffusion instead of liquid effusion prevents the formation of ice and residue in temperatures as low as -40?C.

All-glass heat pipe is manufactured by Guangpu Solar Energy Project Co.,Ltd, a leading manufacturer of all-glass evacuated solar collector tubes in China. There are two vacuums in an all-glass heat pipe, the one in the inner tube and the one between the inner tube and the outer tube. The inner tube absorbs the solar energy, which is transferred to heat. The temperature in the inner tube rises up and the liquid in the inner tube evaporates. The gas rises up to the condenser where it transfers the heat to the water in the tank, so the gas loses its heat and changes into liquid which then flows down to the bottom of the tube because of the gravity. Such a circulation will continue as long as the sun shines. Here is the specifications of All-glass heat pipe:
