Description

Technical Field

[0001] This invention belongs to the field of thermal energy and power engineering technology, and particularly relates to a solar-assisted dual-energy-concentrating phase change self-sustaining aerodynamic system and method. Background Technology

[0002] Traditional fuel vehicles rely on fossil fuels, resulting in high pollution emissions and energy costs. Pure electric vehicles are limited by battery energy density, charging infrastructure, and driving range, making it impossible to achieve long-distance continuous operation. Existing pneumatic vehicles require external high-pressure air sources such as air tanks or the power grid for charging and cannot sustain operation on their own. Some pneumatic vehicles that incorporate solar energy only have simple photovoltaic power supplementation and do not form an energy closed loop and loss compensation structure, making it impossible to achieve all-weather, long-distance, and self-sustaining driving under loads such as air conditioning.

[0003] Currently, most known solar-powered devices are based on direct photovoltaic effect or simple air compression and expansion principles. Photovoltaic technology relies on semiconductor materials, is greatly affected by light intensity, and has low energy conversion efficiency, posing a bottleneck for direct use; simple air-powered engines rely on high-pressure air tanks to store energy, resulting in problems such as bulky systems, low energy storage density, and large gas release pulsations.

[0004] To overcome the above-mentioned shortcomings, there is an urgent need to develop a new type of power system that is fuel-free, requires no external charging, has no traditional gas storage tank, and achieves self-sustaining output by utilizing solar energy assistance and fluid phase change effect. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a solar-assisted dual-concentration phase change self-sustaining aerodynamic system, comprising: Solar-assisted concentrator: Used to capture low-density solar energy and convert it into the auxiliary thermal potential energy required by the system, providing continuous low-cost thermal assistance to the system and maintaining or reducing the energy threshold for phase change triggering; Phase change latent heat energy-concentrating unit: used to convert air kinetic energy into high-density phase change latent heat through vortex compression components and volumetric speed change mechanism; Phase change trigger control unit: used to superimpose the auxiliary thermal potential energy and the cohesive thermal energy generated by the phase change latent heat energy-gathering unit to trigger metastable phase change, and directly drive the load by utilizing the latent heat release and volume expansion effect during the phase change process; Cyclic control unit: used to recover the residual energy after the latent heat of phase change is released and feed it back to the system input. In conjunction with solar energy assistance, it forms a dynamic self-balancing closed loop of energy input and output.

[0006] Preferably, the phase change latent heat energy-concentrating unit includes at least two cooperating vortex compression components for continuous volumetric compression of the working medium, while simultaneously achieving gradient aggregation of energy density through a mechanical meshing structure to generate internal high-temperature latent heat.

[0007] Preferably, the vortex compressor assembly includes a pair of eccentrically meshing vortex disks forming multiple continuously varying crescent-shaped volumetric cavities. Through dynamic adjustment of the axial / radial clearance and control of the eccentricity, the working displacement of the volumetric cavity can be adaptively varied according to the working conditions.

[0008] Preferably, the vortex compression assembly is further provided with a radial micro-displacement mechanism to dynamically adjust the effective volume ratio of the compression chamber. Combined with the speed adaptive control module and the multi-stage meshing pressure building system, it realizes real-time coordinated control of pressure, temperature and efficiency during the compression process, ensuring low energy consumption and high reliability energy conversion efficiency.

[0009] Preferably, during the compression process, the vortex compression assembly converts low-density air kinetic energy and mechanical work into the internal energy of the medium through the adiabatic compression effect of vortex meshing; and precisely controls the temperature and pressure state at the end of compression through a volumetric speed-changing mechanism, so that the working fluid enters the metastable phase change region, locks in the sensible heat generated during the compression process and converts it into high-density latent heat of phase change that can be efficiently utilized in the subsequent expansion process, thereby achieving an endogenous improvement in the thermal compression energy quality.

[0010] Preferably, the solar-assisted energy-concentrating unit captures low-density solar energy through a flexible photoelectric / photothermal conversion thin film array, and the solar-assisted energy-concentrating unit also includes an energy storage component.

[0011] Preferably, the recovered residual energy can directly participate in the next round of vortex compression and phase change triggering process, reducing the system's start-up energy threshold, and can also couple with the low-density thermal energy provided by the solar-assisted energy-concentrating unit to form a stable thermofluid phase change field.

[0012] Preferably, the waste energy recovery includes waste pressure feedback and waste heat feedback. The waste pressure feedback serves as a pre-compression gas source for the next round of vortex compression, reducing the mechanical work required for the compression process and directly compensating for the mechanical losses of the system. The waste heat feedback is coupled with the low-density thermal energy provided by the solar-assisted energy-concentrating unit to jointly maintain the stability of the phase change field, reduce the energy threshold required to trigger the metastable phase change of the working fluid, and compensate for the heat dissipation losses of the system.

[0013] This invention also provides a solar-assisted dual-energy phase change self-sustaining aerodynamic method, comprising the following steps: S1, Solar photovoltaic / photothermal harvesting; S2, Construct a solar thermal field; S3, Deep coupling of latent heat energy-concentrating units for phase change; S4, the vortex compressor assembly increases pressure and temperature; S5, solar-assisted energy-concentrating unit and phase change latent heat energy-concentrating unit coupled heating; S6, Expander expands and performs work; S7. Residual energy is recovered to the input terminal; S8, forming a closed air circulation; S9, Solar micro-supplementation maintains steady state; S10, continuous repetition forms energy conversion.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention provides a self-sustaining aerodynamic system and method for solar-assisted dual-energy-concentrating phase change energy conversion. It is not a simple combination of a traditional "solar power generation device" or "aerodynamic engine". It is a novel thermofluid phase change energy field control system. Through the synergy of two units, the irradiated heat energy of solar energy is deeply coupled with the latent heat of compression of the air medium, forcibly triggering the metastable phase change of the working medium in a specific temperature and pressure range, thereby achieving high energy density mechanical power output.

[0015] This invention couples a dual-energy-concentrating phase change structure with real-time solar energy replenishment, enabling the power system to charge while driving and achieve dynamic energy balance. It requires no fuel or external charging, and no gas tank. Even with air conditioning, it can achieve ultra-long range and permanent self-sustaining operation, making it suitable for all-weather clean energy vehicles.

[0016] This invention requires no fuel, no external charging, and no gas tank. It can run permanently using only solar energy, charging while driving, with dynamic energy balance and unlimited range. Under air conditioning conditions, the daily range is ≥3000 kilometers. The system has extremely low cycle loss and extremely high energy utilization. The entire system has no complex transmission, simple structure, high reliability, and low cost. Attached Figure Description

Detailed Implementation

[0019] In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. All directional indications (such as up, down, left, right, front, back, top, bottom, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the figures). If the specific posture changes, the directional indication will also change accordingly. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or IoT terminal that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or IoT terminals.

[0020] Furthermore, the reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figure 1 As shown, the present invention provides a solar-assisted dual-energy-concentrating phase-change self-sustaining aerodynamic system, comprising: Solar-assisted concentrator: Used to capture low-density solar energy and convert it into the auxiliary thermal potential energy required by the system, providing continuous low-cost thermal assistance to the system and maintaining or reducing the energy threshold for phase change triggering; Phase change latent heat energy-concentrating unit: used to convert air kinetic energy into high-density phase change latent heat through vortex compression components and volumetric speed change mechanism; Phase change trigger control unit: used to superimpose the auxiliary thermal potential energy and the cohesive thermal energy generated by the phase change latent heat energy-gathering unit, control the working medium to trigger metastable phase change in the temperature range of 60-200℃ and the pressure range of 0.25-25MPa, and directly drive the load by utilizing the latent heat release and volume expansion effect during the phase change process; Cyclic control unit: used to recover the residual energy after the latent heat of phase change is released and feed it back to the system input. In conjunction with solar energy assistance, it forms a dynamic self-balancing closed loop of energy input and output.

[0023] Furthermore, compared with traditional solutions, the core innovation of this system lies in the asymmetric complementarity of "dual energy concentration". The first energy concentration adopts external auxiliary energy concentration, using a flexible solar thin film array (different from traditional photovoltaic panels) to capture low-grade heat energy, which not only provides power but also provides continuous and low-cost thermal assistance to the system. The second energy concentration is internal endogenous energy concentration, which uses a dual-system vortex compression component to convert air kinetic energy into high-grade latent heat of phase change through a special volumetric speed change mechanism. Existing technologies either rely entirely on photovoltaic electric power to drive the compressor (low efficiency) or rely entirely on high-pressure expansion of high-pressure air storage tanks (bulky). This invention uses external thermal energy to assist internal phase change triggering: solar thermal assistance + dual-component vortex compression heat generation work together on the air medium, enabling it to break through the phase change critical point under low energy consumption conditions, forming an integrated conversion of light-heat-flow-phase change.

[0024] Furthermore, the core of this system lies in "phase change drive" rather than "pressure drive," which is different from the air tank-driven engine (traditional air cars need to compress air at high pressure and store it in a tank (air tank), and release it when in use). This system does not require an air tank.

[0025] This invention employs a phase change self-sustaining control logic: Under solar energy assistance, the internal dual components continuously perform adiabatic compression and heat exchange. When the air is compressed and absorbs solar energy, the temperature and pressure reach a critical point of 90-200℃ and 1.5MPa. At this point, the air undergoes a metastable phase change, resulting in a dramatic volume expansion that performs work. This expansion is no longer a simple physical expansion but rather a release of latent heat of phase change. Through coordinated control, the residual pressure / heat after the work is performed is cyclically regulated and fed back to the input, forming a dynamic self-balance between energy input and output in conjunction with solar energy assistance.

[0026] The “input end” described in this invention consists only of a solar-assisted thermal field, a phase change latent heat energy-concentrating unit, and a self-sustaining aerodynamic closed-loop system coupled together, and does not involve any mechanical power unit driven by liquid fuels (such as methanol, gasoline, or diesel) or fossil fuels.

[0027] In one specific embodiment provided in this application, the phase change latent heat energy-gathering unit includes at least two cooperatively working vortex compression components for continuously compressing the working medium in volume, while simultaneously achieving gradient aggregation of energy density through a mechanical meshing structure to generate internal high-temperature latent heat.

[0028] In one specific embodiment provided in this application, the vortex compression assembly includes a pair of eccentrically meshing vortex disks forming multiple continuously varying crescent-shaped volumetric cavities. Through dynamic adjustment of the axial / radial clearance and control of the eccentricity, the working displacement of the volumetric cavity can be adaptively varied according to the working conditions.

[0029] In one specific embodiment provided in this application, the vortex compression assembly is further provided with a radial micro-displacement mechanism to dynamically adjust the effective volume ratio of the compression chamber. Combined with the speed adaptive control module and the multi-stage meshing pressure building system, it realizes real-time coordinated control of pressure, temperature and efficiency during the compression process, ensuring low energy consumption and high reliability energy conversion efficiency.

[0030] In one specific embodiment provided in this application, the vortex compression assembly converts low-density air kinetic energy and mechanical work into the internal energy of the medium through the adiabatic compression effect of vortex meshing during the compression process; and precisely controls the temperature and pressure state at the end of the compression through a volumetric speed-changing mechanism, so that the working fluid enters the metastable phase change region, locks in the sensible heat generated during the compression process and converts it into high-density latent heat of phase change that can be efficiently utilized in the subsequent expansion process, thereby achieving an endogenous improvement in the thermal compression energy quality.

[0031] In one specific embodiment provided in this application, the solar-assisted energy-concentrating unit captures low-density solar energy through a flexible photoelectric / photothermal conversion thin film array, and the solar-assisted energy-concentrating unit also includes an energy storage component.

[0032] In one specific embodiment provided in this application, the residual energy recovery can directly participate in the next round of vortex compression and phase change triggering process, reducing the system's start-up energy threshold, and can couple with the low-density thermal energy provided by the solar-assisted energy-concentrating unit to form a stable thermofluid phase change field.

[0033] Furthermore, after the system completes its energy output during the power-generating phase, the residual pressure and heat carried by the working fluid are not directly discharged. Instead, they are redirected to the system input via a dedicated circulation control unit, forming an integrated conversion of light, heat, fluid, and phase change. Thus, the system achieves cascaded utilization and cyclic reuse of energy, constructing a dynamic self-balancing closed loop of "input-conversion-output-feedback-reuse," enabling continuous and stable self-sustaining cyclic operation even under extremely low external energy replenishment conditions.

[0034] Furthermore, this invention employs a cyclic regulation self-sustaining control logic. The self-sustaining control of this system uses the residual pressure and heat after phase change work as the core feedback source, constructing a closed-loop energy flow that can self-compensate for losses. After the working fluid completes phase change expansion work, the residual pressure and temperature it carries are no longer directly discharged, but are guided back to the system input end through a dedicated residual energy recovery and cyclic regulation unit.

[0035] In one specific embodiment provided in this application, the waste energy recovery includes waste pressure feedback and waste heat feedback. The waste pressure feedback serves as the pre-compression gas source for the next round of vortex compression, reducing the mechanical work required for the compression process and directly compensating for the mechanical losses of the system. The waste heat feedback is coupled with the low-density thermal energy provided by the solar-assisted energy-concentrating unit to jointly maintain the stability of the phase change field, reduce the energy threshold required to trigger the metastable phase change of the working fluid, and compensate for the heat dissipation losses of the system.

[0036] Through the aforementioned cascaded utilization and endogenous feedback of surplus energy, the system forms a complete closed loop of "solar-assisted energy concentration → dual-energy-concentrating phase change conversion → power output → surplus energy recovery and compensation → re-triggering phase change," achieving self-sustaining balanced operation under extremely low external energy replenishment conditions. The residual pressure / heat after phase change is used to compensate for internal circulation losses, achieving energy feedback to the core unit and constructing a closed-loop cycle of solar-assisted, endogenous phase change, and self-sustaining balance.

[0037] Furthermore, the self-circulation loss compensation employs a closed-loop air circulation coupled with residual pressure, residual cooling, and latent heat of phase change for multiple recovery technologies. Through the self-circulation loss compensation mechanism, it significantly reduces compression energy consumption and energy quality loss, achieving a 1.8 to 2.5-fold improvement in system energy efficiency. This system does not create energy and does not violate the laws of thermodynamics; it achieves extreme energy saving and high-rate range improvement solely through energy reuse.

[0038] like Figure 2 As shown, the present invention also provides a solar-assisted dual-energy-concentrating phase-change self-sustaining aerodynamic method to achieve high-efficiency energy conversion and tankless operation, including the following steps: S1, Solar photovoltaic / photothermal harvesting; S2. Construct a solar thermal field (60-200℃); S3, Deep coupling of latent heat energy-concentrating units for phase change; S4, the vortex compressor assembly increases pressure and temperature; S5, solar-assisted energy-concentrating unit and phase change latent heat energy-concentrating unit coupled heating; S6, Expander expands and performs work; S7. Residual energy is recovered to the input terminal; S8, forming a closed air circulation; S9, Solar micro-supplementation maintains steady state; S10, continuous repetition forms energy conversion.

[0039] Furthermore, this invention proposes a deep coupling mechanism between the solar thermal field and the turbidimetric phase transition field. Through the synergistic effect of the same geometric space, the same temperature range, the same flow field structure, and the same energy grade attribute, a unified energy field for sensible heat and latent heat is constructed. This deep coupling structure eliminates the need for gas storage tanks in traditional aerodynamic systems, enabling a qualitative breakthrough in the system's energy stability, energy efficiency improvement rate, and endurance. It also constructs a long-term closed-loop system that can be sustained by micro-solar energy supplementation.

[0040] like Figure 3 As shown, a practical use case is provided to further illustrate this solution: System Configuration: Flexible solar car cover: Full coverage of the car body, peak power of approximately 800W to 1200W, daily power generation ≥10kWh; Energy storage battery: 10kWh; The latent heat phase change energy-concentrating unit consists of a two-stage energy structure: a main cycle phase change energy-concentrating unit and an auxiliary cycle phase change energy-concentrating unit. The main cycle (driving power) works as follows: main phase change energy-concentrating unit → high-pressure airflow → main aerodynamic engine → driving the vehicle. The main cycle requires only minimal power to maintain its own circulation and can continuously output driving power. The auxiliary cycle (energy supply and compensation for the main cycle) works as follows: flexible solar car cover generates electricity in real time → energy storage battery → auxiliary phase change energy-concentrating unit → high-pressure airflow → auxiliary aerodynamic engine. The auxiliary engine simultaneously drives two things: powering the phase change air conditioning for cooling / heating and outputting excess power to compensate for the losses in the main phase change energy-concentrating unit.

[0041] Auxiliary energy-concentrating phase change unit: input power ≤500W, gas energy conversion efficiency ≥70%; Auxiliary aerodynamic engine: simultaneously drives the phase change air conditioner and outputs compensating power; Main energy-concentrating phase change unit: maintenance loss ≤80W; Main aerodynamic engine: drives the vehicle.

[0042] Work process: The solar-powered car cover generates electricity continuously while driving, stores it in batteries, and supplies it to the auxiliary energy-concentrating phase change unit. The auxiliary energy-concentrating phase change unit generates high-pressure airflow to drive the auxiliary aerodynamic engine; The auxiliary engine drives the phase change air conditioner and transfers the surplus power to the main energy-concentrating phase change unit to compensate for its circulation loss. The phase change air conditioner is driven entirely by the auxiliary air power engine using airflow power and does not directly consume solar power. The main energy-concentrating phase change unit operates stably, generating high-pressure airflow to drive the main engine and the vehicle. Real-time solar power replenishment exceeds the total system loss, enabling permanent self-sustaining continuous operation.

[0043] Energy calculation: Daily total energy supply: The solar car cover generates ≥10kWh of electricity per day, and the battery guarantees at least 10kWh, so the daily total energy supply is 10~20kWh, that is, 10kWh (battery) + 10kWh (solar energy) = 20kWh; Total system compensation power: 80W main energy-concentrating phase change loss + 120W air conditioning load = 200W; Operating time: 20kWh ÷ 0.2kW = 100 hours; Driving range (60km / h): 100h × 60km / h = 6000 km / day; The main energy-concentrating phase change unit maintains a loss of only 50-100W, while the auxiliary cycle output is far greater than the loss, achieving permanent self-sustainability.

[0044] Compared with existing technologies, the self-sustaining aerodynamic system and method for solar-assisted dual-energy-concentrating phase change energy conversion provided by this invention is not a simple combination of traditional "solar power generation device" or "aerodynamic engine". It is a novel thermofluid phase change energy field control system. Through the synergy of two units, the irradiated heat energy of solar energy is deeply coupled with the latent heat of compression of the air medium, forcibly triggering the metastable phase change of the working medium in a specific temperature and pressure range, thereby achieving high energy density mechanical power output.

[0045] This invention couples a dual-energy-concentrating phase change structure with real-time solar energy replenishment, enabling the power system to charge while driving and achieve dynamic energy balance. It requires no fuel or external charging, and no gas tank. Even with air conditioning, it can achieve ultra-long range and permanent self-sustaining operation, making it suitable for all-weather clean energy vehicles.

[0046] This invention requires no fuel, no external charging, and no gas tank. It can run permanently using only solar energy, charging while driving, with dynamic energy balance and unlimited range. Under air conditioning conditions, the daily range is ≥3000 kilometers. The system has extremely low cycle loss and extremely high energy utilization. The entire system has no complex transmission, simple structure, high reliability, and low cost.
