Abstract
A heat pipe for converting solar energy into thermal energy comprising an envelope provided with an evaporator region and a condensor region, a quantity of vaporizable working fluid within the envelope, a wick within the envelope having capillary means for transporting the working fluid, and, preferably, evacuated transparent container means surrounding the evaporator region for insulating the evaporator region. The evaporator region of the heat pipe is made from a material which is substantially transparent to radiation in a selected range of the solar spectrum, and a wick therewithin which substantially absorbs radiation in at least a portion of the range of the solar spectrum transmitted through the evaporator region. Solar energy is thereby converted into thermal energy or heat directly within the wick, and the heat generated within the wick causes portions of the working fluid therein to evaporate.
