Embodiment Construction

[0022] The composition and the structural relationship of the vacuum tube driven conical casing accelerated exhaust fan of the present invention are:

[0023] The above-mentioned vacuum tube-driven conical casing acceleration exhaust fan is composed of a vacuum tube (1), an inner conical wall (3), and an outer conical wall (2). The outer conical wall (2) and the inner conical wall also form the solar heat collecting sandwich wall. The vacuum tube (1), the outer conical wall (2), and the inner conical wall (3) are coaxially arranged. See figure 1 , Figure 2, Figure 3, Figure 4 .

[0024] The setting of its vacuum tube (1) of vacuum tube driven conical casing of the present invention to accelerate exhaust fan is:

[0025] The above-mentioned vacuum tube drives the conical casing to accelerate the exhaust fan, and the vacuum tube (1) adopts a vertical straight-through vacuum tube. , the upper opening is directly connected to the inlet of the inner conical wall (3), coaxiall...

Abstract

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.

Description

technical field [0001] The invention relates to a solar heat collection drive driven by a straight-through vacuum tube, a conical sleeve is used for the same solar heat collection in the outlet section, and the conical tube shrinks the flow channel to accelerate the air flow. technology field. Background technique [0002] Most of the existing ventilation technologies use power-consuming fans to exhaust air, which directly or indirectly has environmental and energy costs. It is not common to use renewable energy such as solar energy to directly drive fan exhaust. The latter is a purely natural way of passive homogeneity, which needs to be fully developed. [0003] The existing natural ventilation methods still have technical problems such as insufficient ventilation intensity, limited application occasions and methods. Contents of the invention [0004] Based on the above difficulties and deficiencies, the present invention provides a straight-through vacuum tube, and a...
