Abstract
Description
Technical Field
[0001] This invention belongs to the field of fluid control and electrophysics technology, specifically relating to a programmable wind field generation system based on corona ion wind and its control method. Background Technology The basic principle of corona ion wind is: applying high voltage between an electrode with a very small radius of curvature and another electrode, forming an extremely strong electric field near the needle tip, ionizing air molecules into charged ions. These ions accelerate under the action of the electric field force, constantly colliding with the surrounding uncharged neutral air molecules, transferring momentum to them through collisions, and forming a directional airflow on a macroscopic scale. Existing ion wind devices suffer from the following technical defects: First, the wind field pattern is monotonous; all electrodes are subjected to the same voltage, resulting in a single type of ion wind that cannot be flexibly adjusted according to actual needs. Second, the response speed is slow; the control methods in existing technologies are still simple switching or flow regulation, which cannot achieve real-time reconstruction of the wind field pattern. Third, the application scenarios are limited; existing ion wind devices are designed for single application scenarios, and the same set of hardware cannot achieve different functions through software switching. Fourth, the control precision is limited; the controlled object is only the air volume, without involving precise control and real-time reconstruction of the wind field pattern. Therefore, developing a programmable wind field generation system that can flexibly construct various ion wind fields on the same device by independently controlling the voltage combination of each array electrode and can achieve millisecond-level real-time switching is of great technical significance and application value. Summary of the Invention (a) Technical problems to be solved This invention provides a programmable wind field generation system and its control method based on corona ion wind, in order to solve the technical problems of existing ion wind devices, such as single wind field shape, inflexible adjustment, slow response speed, and limited application scenarios. (II) Technical Solution A programmable wind field generation system based on corona ion wind includes multiple discharge electrodes (1) arranged in an array, at least one collection electrode (2) and a control module (3). Multiple discharge electrodes (1) are arranged in an array, and each discharge electrode (1) is powered independently. At least one collecting electrode (2) is arranged opposite to each discharge electrode (1). The control module (3) is independently electrically connected to each discharge electrode (1) and stores multiple sets of voltage combination parameters, each set of voltage combination parameters corresponding to a preset ion wind field. The control module (3) retrieves the corresponding voltage combination parameters according to the target wind field morphology, and constructs the target ion wind field in the target space by independently adjusting the power supply voltage of each discharge electrode (1). The system has no mechanically moving fan. The preset ion wind field can be any one of the following: parallel wind field, converging wind field, diverging wind field, rotating wind field, vortex wind field, or composite wind field. The control module (3) is configured to build a first-type wind field in the first time period and switch to build a second-type wind field in the second time period, with a switching time of 1 millisecond to 100 milliseconds. The control module (3) is configured to operate in multiple working modes, and the control module (3) constructs different ion wind fields under different working modes. The control module (3) is also configured to: generate thrust vectors in different directions by adjusting the voltage combination of discharge electrodes (1) at different positions to control the attitude of the aircraft; adjust the voltage combination of discharge electrodes (1) at the corresponding position in milliseconds according to the attitude data detected by the inertial measurement unit to generate a reaction force to counteract external disturbances; identify the location of local hot spots according to the temperature distribution detected by the temperature sensor, adjust the voltage combination of discharge electrodes (1) at the corresponding position in milliseconds to generate focused ion wind to cool the hot spots; construct an ion wind field with wind speed gradient for sorting according to the difference in physical parameters between the target and other components in the mixture; adjust the voltage combination of each discharge electrode (1) in milliseconds according to the environmental parameters in front to adjust the attitude of the air cushion levitation vehicle. This invention also provides a programmable wind field generation method based on corona ion wind, comprising the following steps: S1: Provides multiple discharge electrodes (1) arranged in an array, each discharge electrode (1) is powered independently; S2: Determine the target voltage combination of each discharge electrode (1) according to the target wind field morphology; S3: Apply the target voltage combination to each discharge electrode (1) to generate corona discharge and form ion wind, and construct the target wind field morphology in the target space; S4: Switch to the second target voltage combination within 1 to 100 milliseconds to construct the second target wind field pattern; The method does not use mechanical moving fans to drive the airflow throughout the entire process. (III) Beneficial Effects First, this invention realizes a paradigm shift from hardware-determined wind fields to software-programmed wind fields. By independently controlling the voltage combination of each array of electrodes, various forms of ion wind fields, such as parallel wind, converging wind, diverging wind, rotating wind, and vortex wind, can be constructed on the same set of hardware, which is impossible for existing fixed-voltage ion wind devices. Secondly, this invention achieves the unexpected technical effect of millisecond-level real-time switching. Wind field switching is achieved through voltage regulation with a response time in the millisecond range, compared to the second-level response time of a multi-fan wind tunnel. This three-order-of-magnitude improvement in response speed makes real-time dynamic programming of the wind field possible, something mechanical fans could never achieve. Third, this invention achieves cross-domain applicability with one machine for multiple uses. The same set of hardware can realize multiple functions such as aircraft attitude control, robot dynamic balancing, precise cooling of chip hotspots, material sorting, and attitude control of air-cushioned vehicles by switching software. Fourth, this invention achieves lightweight, vibration-free, and noise-free adaptability to extreme environments. With no moving mechanical parts, it eliminates mechanical wear and noise, enabling stable operation in extreme environments where traditional mechanical fans cannot function, such as vacuum, microgravity, and strong vibration.

Detailed Implementation Example like Figure 1 and Figure 2 As shown, a programmable wind field generation system based on corona ion wind includes multiple discharge electrodes (1) arranged in an array, at least one collection electrode (2) and a control module (3). The discharge electrode (1) is a needle-shaped electrode with a tip curvature radius of 0.1 mm to 0.5 mm, arranged in a rectangular array, a ring array, or a honeycomb array. The collecting electrode (2) is a flat plate electrode or a ring electrode, arranged opposite to the discharge electrode (1), and the distance between the discharge electrode (1) and the collecting electrode (2) is 5 mm to 25 mm. The control module (3) is independently electrically connected to each discharge electrode (1) and stores multiple sets of voltage combination parameters. The control module (3) independently adjusts the power supply voltage of each discharge electrode (1), with the power supply voltage range being 5kV to 20kV, to construct an ion wind field of a preset shape in the target space. Example This embodiment demonstrates voltage combination control methods for different wind field patterns. The parallel wind field is formed by applying the same voltage to all discharge electrodes (1), generating a uniform directional ion wind. The converging wind field is formed by applying a higher voltage to the outer discharge electrodes (1) and a lower voltage to the central discharge electrode (1), with the ion wind converging from the periphery to the center. The diverging wind field is formed by applying a higher voltage to the central discharge electrode (1) and a lower voltage to the outer discharge electrodes (1), with the ion wind diverging from the center to the periphery. The rotating wind field is formed by applying different voltages sequentially to the discharge electrodes (1) in a ring array along the ring direction, with the ion wind forming a rotating airflow within the ring channel. The vortex wind field is formed by arranging the discharge electrodes (1) along the circumferential direction and setting them tangentially at an angle of 15° to 45°. The control module (3) sequentially applies pulse voltages to each discharge electrode (1), forming a vortex airflow with a suction effect. Example The control module (3) is configured to construct a first-mode wind field in the first time period and switch to construct a second-mode wind field in the second time period, with a switching time of 1 millisecond to 100 milliseconds. The sensor module (4) monitors the environmental parameters in the target space in real time and feeds back the monitoring data to the control module (3). The control module (3) dynamically adjusts the voltage combination of each discharge electrode (1) according to the feedback data from the sensor module (4) so that the actual wind field shape is close to the preset wind field shape, forming a closed-loop control. Example This embodiment applies a programmable ion wind system to aircraft attitude control. Multiple array-type corona ion wind generators are arranged in different parts of the aircraft, and the discharge electrode (1) of each generator is independently connected to the control module (3). The control module (3) calculates the required thrust vector in milliseconds based on the flight attitude data detected by the inertial measurement unit, and immediately adjusts the voltage combination of the discharge electrode (1) at the corresponding position to generate thrust in different directions, thereby realizing the pitch, yaw and roll control of the aircraft. Example This embodiment applies a programmable ion wind system to precisely cool chip hotspots. Multiple array-type corona ion wind generators are arranged above or around the chip. Temperature sensors monitor the temperature distribution on the chip surface in real time and identify the location of local hotspots. When an abnormal temperature rise is detected in a certain area, the control module (3) calculates the required cooling airflow and direction within milliseconds and immediately adjusts the voltage combination of the discharge electrodes (1) at the corresponding position to generate focused ion wind for targeted cooling of the hotspot. As the chip's operating state changes, the hotspot position may move. The control module (3) dynamically adjusts the voltage combination of each discharge electrode (1) through real-time temperature feedback, so that the focus of the ion wind follows the movement of the hotspot, achieving dynamic tracking targeted cooling.
