The invention discloses a solar greenhouse micro-heat pipe array heat storage wall and a preparation method thereof and belongs to the technical field of agricultural facilities. The heat storage wall is sequentially composed of a heat insulation layer, a bearing building block layer, a micro-heat pipe module layer and a cement mortar layer from exterior to interior. The micro-heat pipe module layer is formed by building micro-heat pipe building blocks and building block bricks. Each micro-heat pipe building block is formed in the mode that condensation segments of a plurality of Z-shaped micro-heat pipes are arranged in parallel and inserted into a die and concrete is added for pouring and maintaining. Each micro-heat pipe is formed in the mode that an aluminum plate is stamped, a plurality of parallel micro-groove channels are formed in the aluminum plate and then filled with a proper amount of working medium and then sealing is carried out. By combining the requirements for uniformity of heat storing and releasing of the greenhouse wall, the micro-heat pipe building blocks are distributed in an arrayed mode, and the micro-heat pipe array heat storage wall is formed. By means of the micro-heat array technology, the diurnal solar energy is quickly transferred into the greenhouse wall, the heat storage capacity of the interior of the wall is improved, the stored heat energy is released in time at night according to needs of the heat environment in the greenhouse, and therefore the regulating capacity of the solar greenhouse wall for the heat environment in the greenhouse is improved, and the utilization rate of the solar energy by the greenhouse is increased.

A through solar vacuum glass composite transducing pipe with medium thermal-conduction bearing load based on photoelectric thermal transition contains outer glass pipe, photovoltaic battery, conducting wires, heating panel, heat-exchanging inner glass pipe, glass-housed metal electrode, getter metal spring card and blast pipe hush etc. to form the glass ring cavity pipe. Load-bearing pipe and heating-conducting medium are set in the heat-exchanging inner glass pipe. Positive pole of the photovoltaic battery connects with the heating panel with tubal mounting holes. The heating panel is packaged on the heat-exchanging inner glass pipe and heat-conducting medium is fixed with them by a clamp device. Positive poles of photovoltaic battery are electrical insulating. The positive and negative poles are connected in series to join the heat-exchanging inner glass pipe. Positive and negative poles of the photovoltaic battery group are led out by glass-housed metal electrode linking to conducting wires. Load-bearing pipe with one end sealed is equipped in the heat-exchanging inner glass pipe and heat-conducting medium is filled between them, which is sealed and connected by the closed end cap between glass locating nozzle and the load-bearing pipe.
