The invention provides an air exhauster adopting a vacuum
pipe for driving and a conical sleeve
pipe for accelerating and belongs to the technical field of
solar energy. The air exhauster is formed by vertically piling up the
solar energy straight-through type vacuum
pipe and the conical heat collection sleeve which are coaxial, wherein the conical heat collection sleeve is formed by two cones. The air exhauster utilizes the two heat collection cavities of the straight-through type vacuum pipe and the conical sleeve pipe clamping wall to generate high-temperature and high-speed
airflow, accelerating is achieved through the conical pipe, and the strong-pumping air exhauster function is achieved. In the outer side of the air exhauster, the air exhauster function of exhausting air towards the outside world is set at the bottoms of clamping wall passageways, an air suction port of the bottom of the vacuum pipe, an air outlet of the outer side of the top end of the air exhauster and the like. The air pumping and exhausting function of the air exhauster is strong, the high temperature and the high speed of the air heated by the air exhauster are sufficient, and the air exhauster is suitable for multiple purposes such as warming,
drying, heating, ventilating and pushing. The air exhauster on the whole and an
assembly can be subjected to base part modularization overlaying so as to enlarge power. The air exhauster operates in a fully-natural and passive mode,
energy consumption and environmental cost are avoided, materials with lower prices can be adopted,
machining and manufacturing are easy, operating is safe, and maintaining is convenient.
