Shaft type intake and exhaust method and its structure

The present invention relates to a method for the arrangement of airflow and its construction, and more particularly to a person who conducts airflow with natural wind power.

The use of intake and exhaust structures is quite extensive. Whether it is a utility, industrial building or residential design, proper air intake and exhaust structure planning is a very important and common practice to maintain the air quality of the independent space. The main function of the intake and exhaust structure is to promote the flow of gas in a space by the introduction of a specific device, and to exchange the air in the space with the outside air through the flow of the gas, thereby discharging the hot air of the space. Or exhaust gas, and the structure used in the exhaust end is mostly equipped with an air guiding pipe.

Referring to FIG. 1 , the structure of the conventional air guiding tube 9 is mostly a long straight tube. The air guiding tube 9 includes a ventilation duct 91 and an air outlet 92. One end portion 93 of the air guiding tube 9 is connected to the gas to be exchanged. Space, when hot air or exhaust gas is generated in the independent space, an exhaust auxiliary device or a rising buoyancy effect of the hot air is used, so that the gas to be discharged climbs along the air passage 91, and then the air tube 9 is straight. The characteristic is that a chimney effect is generated, and an air pulling action is generated at the air outlet 92, so that the hot air of the independent space is pulled into the air passage 91, and the air outlet 92 is dissipated into the atmosphere along with the upward pressure.

However, the conventional air guiding tube 9 has several problems. In order to enable the air guiding tube 9 to be smoothly vented, the buoyancy effect of relying on the hot air is sometimes insufficient. When the temperature difference is not high, it is necessary to install a row such as a fan. The wind assisting device, which is driven by electric power or other power, has an additional secondary energy dependence on the exhaust device.

In addition, the air outlet 92 is mostly a flush design, and the design is easy to cause the updraft at the air outlet 92 to generate a spoiler phenomenon with the external natural wind, so that the effect of the wind effect of the chimney effect is discounted, if the air outlet is The shape of 92 is not a flush design, and it is more likely to significantly reduce the effect of the exhaust when it encounters a change in wind direction.

The above and other objects, features and advantages of the present invention will become more <RTIgt;

Please refer to FIG. 2 , which is a first embodiment of the method for constructing and discharging airflow according to the present invention, and the structure thereof comprises an outer tube 1, an inner tube 2 and a shroud 3 The inner tube 2 is located in the hollow passage of the outer tube 1, and the shroud 3 is coupled to the second end of the outer tube 1 and the inner tube 2.

The outer tube 1 has a hollow passage, and the outer tube 1 can have any shape or a perfect circle according to the first embodiment of the present invention. The outer tube 1 has a first end 11 and a second end 12.

The inner tube 2 is located in the hollow passage of the outer tube 1, and has a first end 21 and a second end 22. The cross section of the inner tube 2 can be any shape, or a perfect circle according to the first embodiment of the present invention. An annular exhaust passage 23 is formed between the outer walls of the outer tube 1 and the inner tube 2, and the inner tube 2 is hollow to form an air inlet 24. The first end 21 of the inner tube 2 can be provided with a dilator 211 which protrudes from the first end 11 of the outer tube 1.

The shroud 3 can be coupled to the second end 22 of the inner tube 2 by one end. In the embodiment, the shroud 3 is provided with an inner ring wall 31 and an outer ring wall 32. The inner ring wall 31 is provided therein. The second end 22 of the tube 2 is combined, and the outer ring wall 32 of the shroud 3 can be combined with the second end 12 of the outer tube 1. The inner ring wall 31 and the outer ring wall 32 preferably fit the outer tube 1 and The inner tube 2 is circumferentially disposed in a circular shape, and the inner ring wall 31 and the outer ring wall 32 are preferably pivotally connected to the inner tube 2 and the outer tube 1; the other end of the shroud 3 forms an air inlet 33. The air inlet 33 can guide the airflow into the air inlet 24 of the inner tube 2. An exhaust port 34 is formed between the inner ring wall 31 and the outer ring wall 32 of the shroud 3, and preferably has a blocking portion 35 disposed adjacent to the shroud 3 The air inlet 33 is positioned to close the exhaust passage 23 at the place to prevent the high-temperature airflow discharged from the exhaust passage 23 and the low-temperature airflow to be entered from the air inlet 33 to cause a spoiler.

Referring to FIG. 2 again, when the airflow is used in the present invention, the first end 11 of the outer tube 1 and the first end 21 of the inner tube 2 are coupled to a separate space 4, and the inner tube 2 is The dilator 211 extends in the independent space 4, so that the exhaust passage 23 and the intake passage 24 communicate in the independent space 4, and the inlet passage 24, the independent space 4, and the exhaust passage 23 are Air can circulate in each other.

Referring to FIG. 2 again, the direction of the combination of the shroud 3 and the outer tube 1 and the inner tube 2 is preferably adjusted to be rotationally adjusted so that the air inlet 33 of the shroud 3 is oriented to easily receive a lower temperature airflow. In the direction, the low-temperature airflow is collected into the air inlet 24 through the air inlet 33, and then through the dilator 211 provided in the inner tube 2, the low-temperature airflow is diffused to each corner of the independent space 4, and the independent The higher temperature airflow in the space 4 can be discharged through the exhaust passage 23 to achieve the function of air displacement. In addition, the channel cross-sectional area through the dilator 211 is larger than the channel cross-sectional area of the air inlet 24, and the physical characteristic of reducing the flow resistance of the intake air can be generated, so that the low-temperature airflow entering from the shroud 3 can enter the smoother flow more smoothly. Independent space 4 increases the overall intake air volume.

Since the air of the air inlet 24, the independent space 4 and the air passage 23 can circulate with each other, when the low temperature airflow continuously flows from the air inlet 24, the relatively high temperature airflow in the independent space 4 follows. The exhaust passage 23 flows to the exhaust port 34. Since the shroud 3 is located near the air inlet 33, the flow blocking portion 35 is provided, so that the relatively high temperature airflow of the independent space 4 flows upward along the exhaust passage 23 to When the exhaust port 34 is exhausted, the discharged relatively high-temperature airflow does not affect the low-temperature gas flow of the air inlet 33, reducing the turbulence effect, so that the inlet and outlet structure can smoothly operate on natural wind without relying on other exhausts. assisting equipments.

Referring to FIG. 3, this is a second embodiment of the airflow entering and discharging method and the structure thereof. The arrangement of the inner tube 2, the shroud 3 and the independent space 4 of the present embodiment is different from that of the first embodiment. The row structure is roughly the same, and the details will not be described again. The main difference between the arrangement of the embodiment is that the outer tube 1 is composed of a first outer tube 1a and a second outer tube 1b.

The first outer tube 1a and the second outer tube 1b are rotatably pivoted to form the outer tube 1. The first end 11 of the outer tube is connected to the independent space 4. The second end 12 of the outer tube 1 is non-aligned. The exhaust port includes a windward opening 13 and a drainage opening 14, and the second outer tube 1b can adjust the direction with the wind so that the windward opening 11 can greet the external low-temperature airflow direction, the windward opening 13 The exhaust port can be biased as shown in the first embodiment to prevent the high-temperature airflow dissipated in the space and the low-temperature airflow of the shroud 3 from generating a spoiler effect, but whether the flow portion is set It can be determined according to the relative distance between the windward opening 13 and the shroud 3, and is not limited herein.

Referring to FIG. 3 again, the low-temperature airflow enters the independent space 4 through the inlet of the shroud 3, and the airflow impedance is reduced by the action of the expander 211. After entering the independent space 4, the high-temperature airflow follows the exhaust passage 23 to the windward opening 13 or the drainage opening 14, and escapes to the atmosphere. The direction of the second outer tube 1b can be adjusted with the wind direction, so that the windward opening 13 can directly greet the direction of the flow of the low-temperature gas, and when the wind direction is not parallel to the axial direction of the second outer tube 1b, The wind blows the high-temperature airflow from the windward opening 13 to the draining port 14, and since the height of the draining port 14 is lower than the windward opening 13, when the air is blown from the windward opening 13 to the draining port 14, the air passes through The effect of the mutual traction of the airflow will pull the air at the relatively low end of the drainage opening 14, and form a relatively low pressure at the same place, thereby generating a negative pressure effect, so that the air pulling effect at the drainage opening 14 is more obvious. The positive and negative pressure effect of the air flow into and out of the structure is simultaneously affected by the positive pressure effect of the low temperature airflow flowing from the air inlet 24, and the negative pressure effect generated by the relatively low pressure of the air inlet 14, thereby improving the heat rejection efficiency of the inlet and outlet structure.

The shaft type intake and exhaust method and the structure thereof of the present invention are not driven by energy such as electric energy, but are promoted by the collection of natural wind power, and have the effect of saving energy.

The shaft type intake and exhaust method and the structure thereof of the invention have the design of high and low drop difference, can enhance the air pulling effect of the drainage port, and have the effect of increasing air displacement efficiency.

The shaft type intake and exhaust method and the structure thereof of the present invention, the second outer tube and the shroud can adjust the orientation according to the wind direction, avoid the negative effect caused by the change of the wind direction, and have the effect of adjusting the orientation to maintain the air displacement efficiency. .

While the invention has been described in connection with the preferred embodiments described above, it is not intended to limit the scope of the invention. The technical scope of the invention is protected, and therefore the scope of the invention is defined by the scope of the appended claims.
