And the air flow with higher air volume can be used as renewable energy.

Description

Air Flow Amplifier and Its Flow Amplifying Tube

technical field

The invention relates to an air flow amplifier, in particular to an air flow amplifier capable of generating high wind speed and high air volume.

Background technique

Traditional air flow amplifiers use compressed air as the driving air source. The air compressors in the shop output high-pressure and low-flow air. Although the flow of air flow amplifiers can be amplified several times, or even tens of times, the output wind speed is high. Its air outlet is very small, so after its flow rate is enlarged, the air volume is still extremely small, and its uses such as cleaning, drying or heat dissipation of working objects are extremely limited.

If you want to increase the air volume, the possible solution is to connect multiple air flow amplifiers in series, so that the airflow output by them can be used for other purposes, and because the flow amplifier outputs low-pressure airflow, it requires high-pressure air. Therefore, if the air flow amplifiers of all stages are output in series, the airflow output by the first-stage air flow amplifier cannot become the driving airflow source of the second-stage air flow amplifier, and the solution is to add High pressure drives airflow.

For every additional level of air flow amplifier mentioned above, a high-voltage driving airflow source must be added, which means that the supply rate is proportional to the number of stages of air flow amplifier, so the power consumed is not in line with the economic benefits compared with the power of the output airflow .

In view of the above problems, it is necessary to find a feasible solution on how to save the consumed electricity and increase the output power so as to meet the economic benefits.

Contents of the invention

The technical means adopted for reaching the above-mentioned purpose is to make the aforementioned air flow amplifier include:

A wind source tube is hollow, and an air nozzle is formed at one end to provide a low-pressure small air flow;

More than one flow amplifying cylinder, the flow amplifying cylinder has a large diameter end and a small diameter end, a diffusion chamber is formed in the large diameter end, and the flow amplifying cylinder is formed on the cylinder wall of the large diameter end to communicate with the diffusion chamber The air inlet hole of the large-diameter end is formed with an air inlet, which is connected to the air nozzle of the wind source cylinder; the diameter of the inner cylinder of the flow amplification cylinder is tapered from the large-diameter end to the small-diameter end, and the cone-shaped section A suction chamber is formed inside, and an air outlet is formed at the small diameter end, and the air outlet communicates with the suction chamber;

When the above-mentioned flow amplifying cylinder is input with low-pressure and small airflow from the air source cylinder, the diameter of the flow amplifying cylinder is reduced to accelerate the low-pressure and small airflow, resulting in a vacuum in the suction chamber, and the external air is sucked in through each air intake hole. , and merge with the airflow in the suction chamber to accelerate and send out toward the air outlet; when the aforementioned flow amplifying tubes are multi-stage connected in series, it can accelerate the generation of higher-speed and higher-flow airflow to be used as renewable energy.

Detailed ways

Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

Regarding a preferred embodiment of the present invention, please refer to Fig. 1, which includes an air source tube 10 and more than one flow amplification tube 20, wherein:

Please refer to Fig. 2, the air source cylinder 10 in this embodiment has a large diameter end and a small diameter end, and its inner cylinder diameter gradually decreases from the large diameter end to the small diameter end, so as to form a tapered , form an air nozzle 11 at the small-diameter end, and another large-diameter end is provided with a driving device 12, which can blow out a low-pressure small airflow for the air nozzle 11; in this embodiment, the driving device 12 is used A fan; and because the air source cylinder 10 is in the shape of a cone, the airflow generated by the driving device 12 can be accelerated due to the decreasing diameter of the air source cylinder 10, so that the low-pressure small airflow can be further accelerated.

In this embodiment, two flow amplifying tubes are used, namely a first flow amplifying tube 21 and a second flow amplifying tube 22, wherein the first flow amplifying tube 21 is used as the front stage, and the second flow amplifying tube 22 is used as the first stage. In the latter stage, the first and second flow amplifying cylinders 21, 22 have a large diameter end and a small diameter end respectively. The large-diameter end of the second flow amplifying tube 22 of the rear stage; the large-diameter end ends of the first and second flow amplifying tubes 21, 22 form an air outlet 211, 221 respectively, and the small-diameter end ends are adjacent to the center. An air inlet 212, 222 is formed, and the air inlet 212 and the air outlet 222 of the first flow amplifying tube 21 are respectively connected with the air nozzle 11 of the aforementioned wind source tube 10 and the air inlet 222 of the second flow amplifying tube 22; The inner tube diameters of the second flow amplifying cylinders 21, 22 gradually decrease from the large diameter end to the small diameter end, so they are respectively tapered; and the first and second flow amplifying cylinders 21, 22 are respectively formed in their large diameter ends. There is a diffusion chamber 213, 223, and a plurality of air inlets 214, 224 are formed on the wall of the large-diameter end of the first and second flow amplifying cylinders 21, 22, and the plurality of air inlets 214, 224 are respectively connected with The aforementioned diffusion chambers 213, 223 are communicated; in the other first and second flow amplifying cylinders 21, 22, a suction chamber 215, 225 is respectively formed in its conical section, and one end of the suction chamber 215, 225 is connected to the aforementioned diffusion chamber 213 respectively. , 223 are in communication, and the opposite ends are in communication with the air outlets 211 and 221 respectively.

In the hole edge of each air inlet 214 on the above-mentioned first flow amplifying tube 21, a virtual cut surface is formed on the side adjacent to the air outlet 211, and the cut surface is the same plane as the small-diameter end face of the wind source tube 10; In other words, the edge of the inlet hole 224 on the second flow amplifying tube 22 adjacent to the side of the air outlet 221 can form another virtual tangent plane, and this tangent plane is on the same plane as the small-diameter end surface of the first flow amplifying tube 21 .

The flow amplifying cylinder constituted according to the above-mentioned structure mainly utilizes the driving device 12 of the air source cylinder 10 to operate, that is, a low-pressure small airflow is blown out from the air nozzle 11 and sent to the diffusion chamber 213 of the first flow amplifying cylinder 21. The inner diameter of the suction chamber 215 shrinks, so that the low-pressure small airflow sent in is accelerated, and the suction chamber 215 is vacuumed, and the external air is sucked in by each air inlet 214, and after merging with the accelerated low-pressure small airflow, the second air is sent out. The flow amplifying cylinder 22 is used as the driving air flow of the second flow amplifying cylinder 22;

When the driving airflow enters the diffusion chamber 223 of the second flow amplification tube 22 and advances toward the suction chamber 225, the diameter of the pipe in the suction chamber 225 is reduced, so the driving airflow is accelerated, and the suction chamber 225 is vacuumed, The air hole 224 extracts the external air, which can be accelerated and sent out toward the air outlet 221 after converging with the driving air flow; the external air can be continuously sucked from the air intake hole 214 of the first flow amplifying cylinder 21 through continuous operation of the above actions; When the low-pressure small airflow and the air in the suction chamber 215 merge into an airflow process, because the airflow is reduced by the diameter of the first flow amplifying cylinder 21, and then the flow velocity of the airflow is increased, so the wind speed of the driving airflow can be improved; The airflow operation mode in the second flow amplifying cylinder 22 is the same as that of the first flow amplifying cylinder 21, that is, the driving airflow blown in by the first flow amplifying cylinder 21 can merge into the suction chamber 225 and be sucked in from the outside through the air inlet 224 The air to form another driving airflow, and through the tapered section of the second flow amplifying tube 22, the driving airflow blown out of the air outlet 221 can increase its wind speed, so that it can be used in the second flow amplifying tube 22 The air outlet 221 blows out a high-speed and high-flow driving airflow, which can save power resources when used as a fan.

For another preferred embodiment of the present invention, please refer to FIG. 3, which is only a schematic diagram of the structure, that is, if a windmill is further provided at the air outlet 221 of the second flow amplifying tube 20 at the last stage 30 and a generating set 31 connected with the windmill 30, the windmill 30 can be operated by using the air outlet 221 of the second flow amplifying tube 20 to blow out the driving airflow with high wind speed and high flow rate, so that the generating set 31 can be operated, In order to further generate electric energy, it can be seen from the above that the flow amplifying tube 20 can be connected in multiple cascades, and the wind speed and air volume of the final air outlet are proportional to the number of cascades of the flow amplifying tube, so when the number of cascaded connections The more, the higher wind speed and higher air volume can be achieved, so that the use of renewable energy can be more efficient.
