Passive solar water circulation cooling system

无源太阳能水循环冷却系统

Abstract

The invention discloses a passive solar water circulation cooling system, which comprises a civil/industrial water tank, a solar photoelectric conversion board and a solar thermoelectric conversion board. A first water-cooled convection water tank and a second water-cooled convection water tank are respectively arranged under the civil/industrial water tank and the solar photoelectric conversion board, and are connected through a convection water pipe; a convection radiating fin is arranged inside the second water-cooled convection water tank and is connected with the solar photoelectric conversion board or under the solar thermoelectric conversion board; an included angle ranging from 15 degrees to 75 degrees is formed between the whole second water-cooled convection water tank and a horizontal plane; a radiating panel is arranged inside the first water-cooled convection water tank and is provided with a radiating fin; two ends of the radiating fin respectively extend into the civil/industrial water tank and the first water-cooled convection water tank; and a water pipe convection sheet is arranged on the connecting part of the first water-cooled convection water tank and the convection water pipe. The passive solar water circulation cooling system transfers the temperature to the civil/industrial water tank from a solar panel due to natural heat convection phenomenon of water without extra maintenance energy, effectively reduces the temperature of the solar panel simultaneously and increases the temperature difference of the solar thermoelectric conversion board. Therefore, the thermoelectric conversion efficiency is improved, and the service life of the solar photoelectric conversion board can be prolonged.
本发明公开了一种无源太阳能水循环冷却系统,包括民用/工业用水箱、太阳能光电转换板和太阳能热电转换板,所述民用/工业用水箱和太阳能光电转换板下方分别设第一水冷对流水箱和第二水冷对流水箱,两者通过对流水管连接,第二水冷对流水箱中设对流散热片,其接于太阳能光电转换板或太阳能热电转换板之下,第二水冷对流水箱整体与水平面成15度到75度夹角;第一水冷对流水箱中设散热板,其一设散热片,散热片两端分别延伸至民用/工业用水箱和第一水冷对流水箱中;第一水冷对流水箱与对流水管连接处设水管对流片。本发明不需要额外维护能源,通过水的自然热对流现象,将温度从太阳能板上传递到民用/工业用水箱,对太阳能板进行有效的降温的同时,增加太阳能热电转换板的温度差,以增加热电转化的效率,也可以延长太阳能光电转换板的使用寿命。
