The invention provides a U-shaped vacuum
heat pipe type vacuum photo-thermal and photovoltaic conversion glass
pipe, and belongs to the technical field of
solar energy utilization. The U-shaped vacuum
heat pipe type vacuum photo-thermal and photovoltaic conversion glass
pipe is composed of a U-shaped vacuum
heat pipe, a
solar cell piece and the like, wherein the U-shaped vacuum heat
pipe and the
solar energy cell piece are arranged in a glass pipe body, the two pipe ends of the U-shaped vacuum heat pipe extend out of openings of the glass pipe body and are welded to an external positive wire and an
electrode negative wire,
welding opening sealing covers with
kovar alloy serving as solder are arranged on the openings of the glass pipe body, the
solar cell piece and the positive
electrode and the negative
electrode of the
solar cell piece are fixed to the U-shaped vacuum heat pipe through fixing belts, and vacuum suction pipes and vacuum suction pipe plugs are arranged on the
welding opening sealing covers on the openings of the glass pipe body. The U-shaped vacuum heat pipe type vacuum photo-thermal and photovoltaic conversion glass pipe is reasonable and simple in structure, easy to produce and manufacture and low in cost, comprehensive utilization of photoelectricity and optothermal can be achieved through the integral design, and the use efficiency of
solar energy is improved; accordingly, the cost of solar energy application can be further reduced, and a new
train of thought is provided in order to eliminate the influences caused by the high temperature of the photo-thermal and photovoltaic conversion
system.
