A solar greenhouse micro heat pipe array thermal storage wall

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of agricultural facilities, and relates to a micro heat pipe array thermal storage wall in a solar greenhouse. The thermal storage wall can improve the heat storage capacity inside the greenhouse wall, and improve the ability of the solar greenhouse wall to regulate and control the thermal environment in the greenhouse. Greenhouse utilization of solar energy. Background technique [0002] With the continuous advancement of my country's urbanization process, ensuring the safe and stable supply of urban winter vegetables has become one of the important tasks of the modernization of facility agriculture. The solar greenhouse is a kind of facility horticultural building that utilizes solar energy and the greenhouse effect to realize off-season vegetable production in winter. significant economic and ecological benefits. [0003] For a long time, the solar greenhouse has basically adopted a passive heat storage...

AI Technical Summary

Problems solved by technology

Although the thermal environment of the greenhouse has been improved to a certain extent, the indoor surface of the north wall is blocked, the heat storage performance of the wall itself is not fully utilized, and the active heat storage method consumes a lot of electric energy, which increases the initial investment and daily maintenance. Operation and management costs
