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.

The invention provides a phase change heat storage solar water heater with a self-adaption heat dissipating structure. When a phase change heat storage material is overheated, hot gas is generated in a vacuum pipe; along with increment of the temperature, the gas pressure in the vacuum pipe is increased; the longitudinal elastic deformation length of an elastic cover bowl cup structure exceeds the gap height, so that the upper surface of a top plate of a metal heat conducting block is contacted with the bottom of a blind hole of a heat conducting flat plate to form a heat transfer channel from the top plate of the metal heat conducting block to the heat conducting flat plate; the hot gas in the vacuum pipe is dispersed to the top of the vacuum pipe; a vertical cylindrical heat exchange fin of the metal heat conducting block is condensed; and heat generated by condensation is transferred to the heat conducting flat plate from the metal heat conducting block of a self-adaption heat conducting device, and is transferred from a heat dissipating plate to surrounding environments, so that the temperature of the gas in the vacuum pipe is lowered, the stable pressure in the vacuum pipe is maintained, and the overheating protection of the phase change heat storage solar water heater is achieved.
