The invention discloses a closed loop capillary solar photovoltaic thermoelectric plate, belonging to the field of solar photovoltaic generation and solar heat collection, which is characterized in that the device comprises a header tube, a finned tube, a capillary tube, a graphite heat conductive layer, a metal frame, a solar cell plate and a heat-insulating layer, wherein the capillary tube is formed by metal tubes with 2-5mm inner diameter, and is connected with the finned tube to form a closed pipeline system. The capillary tube is filled with heat transfer medium, and the heat transfer medium can absorb the heat energy of the solar cell plate to form a steam liquid column to enter into the finned tube when in work, and then returns to the capillary tube after being cooled and condensed by medium outside the tube, and resorbs the heat energy of the solar cell plate, and is heated to gasify, thereby finishing the heat transfer process through the circulation. The invention has the effects and benefits that the capillary metal tube can timely and effectively conduct away working waste heat of the solar cell plate, reduces the working temperature of the solar cell plate, increases the efficiency of photo-electronic conversion, and simultaneously realizes recycling of the working waste heat of the solar cell plate.
Description
