Description

Technical Field

[0001] This invention relates to an artificial intelligence-controlled containerized energy storage power station cold and hot circulating fan system, mainly used for controlling the cold and hot temperatures of energy storage cell modules installed in the container during charging and discharging. The cold and hot circulating fan system for the containerized energy storage cell modules is controlled by both artificial intelligence technology and dual CAN local area bus control. Therefore, the combination of these two technologies strongly promotes the development of power plants and grid-connected energy storage cell modules, strengthens the distributed circulating control of the cold and hot temperatures of new energy storage cell module systems, and has a very broad application prospect. Background Technology

[0002] Artificial intelligence, in essence, is a revolution in energy and computing power. Every realization of a large-scale intelligent model relies on electricity, and computing power depends on electricity. Therefore, power plants typically store excess electricity in energy storage stations, and the energy storage cells in these stations are often housed in containers. However, the sealed, non-ventilated container structure significantly limits heat dissipation and insulation between the cells, making temperature control a critical issue, as the energy storage efficiency of the cells in an energy storage station is closely related to the ambient temperature. The bidirectional energy storage converter (PCS) connects to the public power grid through energy storage cell modules. During periods of low grid load, it converts AC power from the grid into DC power, which then charges the containerized energy storage cell modules. During periods of high grid load, it converts the DC power from the energy storage cell modules back into AC power that meets grid requirements, feeding it back into the public power grid. In this process, the bidirectional energy storage converter (PCS) operates primarily for bidirectional power conversion through a flexible interface between the energy storage cell modules and the grid. The charging and discharging processes of the energy storage cell modules are highly sensitive to ambient temperature.

[0003] It is evident that the energy storage cells in the container serve as the peak-shaving power source for the power grid, constituting a crucial battery for the energy storage power station. While air conditioning is a common method to improve the temperature variation within the container space, its operating costs are too high. Using electric fans could significantly reduce electricity bills. However, traditional cooling or heating fans are mostly installed directly, resulting in uneven cooling or heating efficiency and poor insulation or heat dissipation for the containerized energy storage cells. To effectively minimize temperature fluctuations during charging and discharging operations between the power grid and the energy storage cells, this invention makes the following attempts: For driving the cold air, a cooling fan with louvers utilizes a semiconductor cooling chip, generating cool air under the control of a permanent magnet brushless DC motor. For driving the hot air, the inventor fully utilizes the patent "A Permanent Magnet Brushless DC Motor with Built-in Controller for a Range Hood" (patent number ZL201610816849.5) designed in 2016. The permanent magnet brushless DC motor is equipped with a fan on its rotating shaft. The installation and operation are similar to installing a range hood, and the operation mode is similar to a blower. In addition, with the help of artificial intelligence technology, a three-dimensional variable frequency wind field has been designed. It mainly creates a circulating air environment inside the container by controlling a spherical circulating fan composed of two blades in a variable frequency manner.

[0004] What makes this invention particularly unique is its integrated housing topology. The cold and hot air blowers, spherical circulating fan, cold source, heat source, and drive motor are all housed within the housing. A dense ion-insulating film is specifically sprayed onto the inner walls of the housing to create a low-absorption-rate insulation environment inside. The determination of whether cold or hot air is generated within the housing comes from two sources: first, a human intervention command on the CAN local area bus; and second, four digital temperature sensors on the PCB circuit board. Since both cold and hot air are generated by the adjustable-speed cooling fan… The hot air is first generated within a low-absorption, insulated shell, and then, under the control of artificial intelligence (AI) technology, is distributed throughout the container by a spherical circulating fan with high emissivity. Therefore, this AI-based three-dimensional variable-frequency airflow ensures that the airflow uniformly and smoothly passes over each energy storage cell component within the container, achieving efficient and uniform exchange and circulation of hot and cold air between the energy storage cells. This effectively solves the problem of uneven heat preservation or dissipation caused by ordinary fans in containerized energy storage power stations using directional direct-discharge methods. It should be noted that the spherical circulating fan is also driven by an adjustable-speed permanent magnet brushless DC motor. Summary of the Invention

[0005] Accordingly, the applicant has proposed a design scheme for an artificial intelligence-controlled cold and hot circulation fan system for a containerized energy storage power station, which is completely different from traditional technical approaches. The details are as follows: The key features of the AI-controlled containerized energy storage power station's cold and hot circulating fan system include: a casing, a spherical circulating fan, a hot blower ventilation mesh panel, a cold fan and louvered side panel, a PCB circuit board, and dual CAN interface sockets. The aforementioned AI-controlled containerized energy storage power station's cold and hot circulating fan system consists of three sets of fans: a spherical circulating fan driven by a permanent magnet brushless DC motor A, a hot blower unit driven by a permanent magnet brushless DC motor B, and a cold fan driven by two permanent magnet brushless DC motors C. All of them are enclosed in a space surrounded by an outer shell. The outer shell is a hollow cube with internal reinforcing ribs, a PCB circuit board, and support columns. The support columns have fixing holes. There are also four outer shell mounting and positioning fixing columns on the outside of the hollow cube, which are convenient for installation on the container wall. The outer shell mounting and positioning fixing columns have internal threaded holes for screw fixing. Since the cold and hot circulation fan system of the AI-controlled containerized energy storage power station adopts the bolt fastening installation mode, it can be installed in any part of the container. Through the variable frequency operation of the spherical circulation fan, it is particularly suitable for heat dissipation or heat preservation of containerized energy storage power stations. The outer casing has a circular opening at the front, into which the spherical circulating fan can be perfectly inserted. The outer casing has screw holes for the spherical circulating fan. After the screw passes through the screw holes of the front and rear fan covers of the spherical circulating fan, it is then connected to the screw holes of the spherical circulating fan on the outer casing. The spherical circulating fan has two sets of fan blades mounted on its rotating shaft. This is a double-layer turbulence fan blade structure, which includes a long fan blade composed of 11 blades and a short fan blade composed of 7 blades. The blades are then fixed by a double-layer fan blade fixing handle, highlighting the spatial structure of the fan resonator. On the one hand, this enhances the airflow power, and on the other hand, it reduces the operating noise of the fan. According to computer simulation calculations, this design allows the spherical circulating fan to produce the maximum circulating wind effect, with a wind force 22 times greater than that of a single fan blade. The rear of the outer shell is a heat blower ventilation mesh cover panel. The heat blower ventilation mesh cover panel has a heat dissipation panel with heat dissipation holes. The heat blower ventilation mesh cover panel also has four heat blower mesh cover mounting positioning rods. Insert the heat blower mesh cover mounting positioning rods into the fixing holes on the support columns of the reinforcing rib support columns respectively to complete the quick assembly of the heat blower ventilation mesh cover panel and the outer shell. The hot air blower has a built-in hot air duct elbow on the vent mesh panel, and the inner wall of the hot air duct elbow is tightly attached with a heating PTC film material. The hot blower is driven by a permanent magnet DC brushless motor B, which looks similar to the motor used in the range hood on a household kitchen stove. In principle, it uses a permanent magnet and DC brushless structure. A fan wheel is installed on the rotating shaft and the handle is tightened with the fan wheel. On the left and right sides of the outer casing are the cooling fan and the louver side panels. To facilitate the installation of the louvers, a rectangular opening is specially made on the outer casing. The screws pass through the mounting holes of the side panels and are then connected to the fixing holes of the upper side panels of the outer casing. The cooling medium of the air cooler is a semiconductor cooling chip and a cooling plate. The front of the permanent magnet brushless DC motor C is mounted in close contact with the cooling plate to obtain a cooling source; the protective mesh cover is mounted in close contact with the back of the permanent magnet brushless DC motor C. During assembly, a PCB circuit board is installed on the bottom of the housing. The PCB circuit board is positioned on four PCB circuit board positioning posts. An ARM microcontroller, a CAN bus interface chip, a driver chip, an optical isolation chip, power transistors F, G, M, and N, an electrolytic capacitor, four digital temperature sensors, two current sensors, an eight-bit micro switch, and two power filters are soldered onto the PCB circuit board. After the PCB board positioning and mounting posts pass through the PCB board mounting holes, the PCB board is fixed to the bottom of the housing. Then, the dual CAN bus interface sockets are passed through the dual CAN socket mounting holes on the housing and soldered to the PCB board mounting holes.

[0006] Furthermore, the outer shell is made of heat-resistant and flame-retardant ABS engineering plastic masterbatch through one-time injection molding.

[0007] Furthermore, all control and interface circuits are concentrated on the PCB circuit board. Following the principle of proximity in wiring, power transistors F and M drive permanent magnet brushless DC motor C, power transistor G drives permanent magnet brushless DC motor A, and power transistor N drives permanent magnet brushless DC motor B, respectively.

[0008] Furthermore, the dual CAN bus interface socket is controlled by the CAN bus interface chip, while the eight-bit micro switch provides 256-bit node address control.

[0009] Furthermore, the ARM microcontroller is a microcontroller based on the ARM architecture that supports artificial intelligence technology and can provide high-performance, low-power AI computing capabilities for edge devices.

[0010] Furthermore, all controllable cold and hot air is generated inside the casing, and then the cold or hot air inside the casing is forcefully discharged through a spherical double-blade circulating fan to achieve efficient exchange, circulation, and neutralization of cold and hot air in the energy storage power station.

[0011] Furthermore, the hot blower, cold fan, and spherical circulating fan are all driven by permanent magnet brushless DC motors. They can operate at variable frequencies under the control of an ARM microcontroller according to the ambient temperature. The permanent magnet brushless DC motors A, B, and C are not only energy-saving and controllable, but can also adjust the opening angle of the louvers and ventilation mesh inside the housing by changing the direction and speed of the motor. This is completely different from the control mode of traditional shaded-pole AC motors. Shaded-pole AC motors are designed for 50 Hz operation, while permanent magnet brushless DC motors are designed for frequencies from 0 to 50 Hz or even higher.

[0012] Furthermore, traditional hot and cold fans mostly adopt direct exhaust or direct blowing methods, resulting in uneven heat dissipation or heating. However, in this embodiment, following the control mode of artificial intelligence, an indirect exhaust method is adopted. That is, all the cold or hot air is generated in advance inside the casing, and then the cold or hot air in the casing is powerfully discharged by the spherical circulating fan through the ARM microcontroller with strong edge computing capabilities, thereby greatly improving the uniform exchange and circulation of cold and hot air between the container energy storage cell components.

[0013] Furthermore, the online dual-channel CAN interface socket has one channel used to control and rewrite the ARM microcontroller's resident program, while the other channel is connected to the CAN interface of the host computer.

[0014] Furthermore, in order to create a thermally insulating environment inside the shell, a dense layer of ion-insulating film was sprayed onto the inner sides of the four walls of the shell. Attached Figure Description

[0018] The specific embodiments of the present invention are described below with reference to the accompanying drawings: It should be noted that screws and nuts are not shown in the accompanying drawings of this embodiment. These conventional components should be well known to those skilled in the art. Due to the large number of drawings, the terms "upper," "middle," "lower," "inner," "outer," "front," "rear," or "left and right" used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the purpose of simplifying the description of this embodiment and do not indicate that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. The inventors specifically declare that in this embodiment, sometimes for convenience, "outer shell" is also referred to as "shell". In fact, both terms are consistent and refer to "outer shell". Do not assume that this will cause ambiguity.

[0019] The details are as follows: The containerized energy storage power station's cold and hot circulating fan system, controlled by artificial intelligence, includes an outer shell (1), a spherical circulating fan (2), a hot blower ventilation mesh panel (3), a cold fan and louver side panel (4), a PCB circuit board (5), and a dual-channel CAN interface socket (6). Its key features are: The containerized energy storage power station cold and hot circulating fan system controlled by artificial intelligence consists of three sets of fans: a spherical circulating fan (2) driven by a permanent magnet brushless DC motor A (2-6), a hot blower unit driven by a permanent magnet brushless DC motor B (3-2), and a cold fan driven by two permanent magnet brushless DC motors C (4-2). They are all encapsulated in the space surrounded by the outer shell (1). The outer shell (1) is a hollow cube with built-in reinforcing rib support columns (1-9) and PCB circuit board (5). There are also four outer shell mounting and positioning fixing columns (1-1) on the outside of the hollow cube, which are convenient for installation on the container wall. The outer shell mounting and positioning fixing columns (1-1) have internal threaded holes, which can be used for screw fixing. Since the cold and hot circulating fan system of the container energy storage power station controlled by artificial intelligence adopts the bolt fastening installation mode, it can be installed in any part of the container. Through the frequency conversion operation of the spherical circulating fan (2), it is particularly suitable for heat dissipation or heat preservation of the container energy storage power station. The outer casing (1) has a circular opening (1-4) at the front, and the spherical circulating fan (2) can be inserted into the circular opening (1-4). The outer casing (1) has screw holes (1-2) for the spherical circulating fan. After the screw passes through the screw holes (2-3) for fastening the front and rear fan covers of the spherical circulating fan, it is connected to the screw holes (1-2) for the spherical circulating fan on the outer casing (1) as a whole. The spherical circulating fan (2) has two sets of fan blades mounted on its rotating shaft. This is a double-layer turbulence fan blade structure, including a long fan blade (2-4) composed of 11 blades and a short fan blade (2-7) composed of 7 blades. The blades are then fixed by a double-layer fan blade fixing handle (2-5), which highlights the spatial structure of the fan resonator. On the one hand, it strengthens the airflow power, and on the other hand, it reduces the operating noise of the fan. According to the calculation of computer simulation, this allows the spherical circulating fan to produce the maximum circulating wind effect, with wind force 22 times greater than that of a single fan blade. The rear of the outer shell (1) is a heat blower ventilation mesh cover panel (3). The heat blower ventilation mesh cover panel (3) has a heat dissipation panel (3-4) with heat dissipation holes. The heat blower ventilation mesh cover panel (3) also has four heat blower mesh cover mounting positioning rods (3-1). Insert the heat blower mesh cover mounting positioning rods (3-1) into the fixing holes (1-10) on the support column of the reinforcing rib support column (1-9) respectively to complete the assembly of the heat blower ventilation mesh cover panel (3) and the outer shell (1). The hot air blower has a built-in hot air duct elbow (3-3) on the ventilated mesh panel (3), and the inner wall of the hot air duct elbow (3-3) is tightly attached to the heating PTC film material. The hot blower is driven by a permanent magnet DC brushless motor B (3-2), which is similar in appearance to the motor used in the range hood on the kitchen stove. In principle, it uses a permanent magnet and DC brushless structure. A fan wheel (3-5) is installed on the rotating shaft and tightened with the fan wheel fastening handle (3-5). On the left and right sides of the outer casing (1), a cooling fan and a louvered side panel (4) are installed. To facilitate the installation of the louvered window, a rectangular opening (1-6) is specially made on the outer casing (1). The screw passes through the mounting hole (4-1) of the side panel and is then connected to the fixing hole (1-7) of the upper side panel of the outer casing. The cooling medium of the air cooler is a semiconductor cooling chip (4-5) and a cooling plate (4-4). The front of the permanent magnet brushless DC motor C (4-2) is closely attached to the cooling plate (4-4) to obtain a cold source. The protective mesh cover (4-3) is closely attached to the back of the permanent magnet brushless DC motor C (4-2). During assembly, a PCB circuit board (5) is installed on the bottom of the outer shell (1). The PCB circuit board (5) is positioned on four PCB circuit board positioning mounting posts (1-11). The PCB circuit board (5) is soldered with an ARM microcontroller (5-1), a CAN bus interface chip (5-2), a driver chip (5-3), an optical isolation chip (5-4), a power transistor F (5-5), a power transistor G (5-6), a power transistor M (5-7), a power transistor N (5-8), an electrolytic capacitor (5-9), four digital temperature sensors (5-10), two current sensors (5-11), an eight-bit micro switch (5-12), and two power filters (5-14). After the PCB board positioning mounting post (1-11) passes through the PCB board mounting hole (5-15), the PCB board (5) is fixed to the bottom of the housing (1). Then, the dual CAN bus interface socket (6) passes through the dual CAN socket mounting hole (1-8) on the housing (1) and is then soldered to the PCB board mounting hole (5-13).

[0020] Furthermore, the outer shell (1) is made of heat-resistant and flame-retardant ABS engineering plastic masterbatch through one-time injection molding.

[0021] Furthermore, all control circuits and interface circuits are concentrated on the PCB circuit board (5). According to the principle of wiring nearby, power transistors F (5-5) and M (5-7) drive permanent magnet brushless DC motor C (4-2), power transistor G (5-6) drives permanent magnet brushless DC motor A (2-6), and power transistor N (5-8) drives permanent magnet brushless DC motor B (3-2).

[0022] Furthermore, the dual CAN bus interface socket (6) is controlled by the CAN bus interface chip (5-2), while the eight-bit micro switch (5-12) provides 256-bit node address control.

[0023] Furthermore, the ARM microcontroller (5-1) is a microcontroller based on the ARM architecture, which supports artificial intelligence technology and can provide high-performance, low-power AI computing capabilities for edge devices.

[0024] Furthermore, all controllable cold and hot air is generated inside the outer shell (1), and then the cold or hot air inside the shell is forcefully discharged by a spherical double-blade circulating fan to achieve efficient exchange, circulation and neutralization of cold and hot air in the energy storage power station.

[0025] Furthermore, the hot blower, cold fan, and spherical circulating fan are all driven by permanent magnet brushless DC motors. They can be operated by frequency conversion under the control of the ARM microcontroller (5-1) according to the ambient temperature. The permanent magnet brushless DC motors A (2-6), B (3-2), and C (4-2) are not only energy-saving and controllable, but can also adjust the opening angle of the louvers and ventilation mesh inside the housing (1) by changing the direction and speed of the motor. This is completely different from the control mode of the traditional shaded-pole AC motor. The shaded-pole AC motor is designed according to the working condition of 50 Hz, while the permanent magnet brushless DC motor is designed according to the frequency of 0 to 50 Hz or even higher.

[0026] Furthermore, traditional hot and cold fans mostly adopt direct exhaust or direct blowing methods, which leads to uneven heat dissipation or heating. However, in this embodiment, following the control mode of artificial intelligence, an indirect exhaust method is adopted. That is, all the cold or hot air is generated in advance in the outer shell (1), and then the cold or hot air in the shell (1) is powerfully discharged by the spherical circulating fan (2) through the ARM microcontroller (5-1) with strong edge computing capabilities, thereby greatly improving the uniform exchange and circulation of cold and hot air between the container energy storage cell components.

[0027] Furthermore, the online dual-channel CAN interface socket (6) has the following functions: one channel is used to control and rewrite the resident program of the ARM microcontroller (5-1), and the other channel is connected to the CAN interface of the host computer.

[0028] Furthermore, in order to create a thermally insulating environment inside the shell (1), a dense ion-insulating film was sprayed onto the inner sides of the four walls of the shell (1). Beneficial effects

[0029] This invention application proposes an AI-controlled containerized energy storage power station cold and hot air circulation fan system. This is not only a method of rapidly heating or cooling using containers, but also a concrete and implementable product. The shell of the AI-controlled containerized energy storage power station cold and hot air circulation fan adopts an integrated topology design. The core chip uses a microcontroller based on the ARM framework, fully supporting artificial intelligence (AI) technology and edge computing. The circulation and exhaust operation of the dual-blade spherical circulation fan is always under the control mode of artificial intelligence and CAN local area network. Furthermore, the direct exhaust method of cold and hot air is changed to a variable frequency circulation exhaust method, thereby ensuring efficient and powerful exchange and circulation of cold and hot air between energy storage cell components inside the sealed container.

[0030] The most substantial improvement of this invention is that, since both cold and hot air are generated first within a low-absorption-rate insulating shell by adjustable-speed cooling fans and hot blowers, and then, under the control of artificial intelligence (AI) technology, are delivered to various parts of the container with high emissivity by spherical circulating fans, this AI-based three-dimensional variable frequency air field ensures that the airflow can uniformly and smoothly pass over each energy storage cell component in the container. This achieves efficient and uniform strong exchange and circulation of cold and hot air between the energy storage cell components in the container, effectively solving the problem of uneven heat preservation or heat dissipation caused by ordinary fans in the directional direct discharge method in containerized energy storage power stations.

[0031] Another unexpected benefit of this invention is that there is currently no such cold and hot circulating fan system for containerized energy storage power stations based on artificial intelligence control on the market. Therefore, its future market position is unique and its application prospects are very broad.

[0032] It should also be noted that since all the fan drive motors in the casing are permanent magnet brushless DC motors, the power supply does not need to provide additional excitation current. Therefore, the drive motors used for the fans are also particularly energy-efficient. Moreover, the speed and direction of the motors are controllable, which means that the intensity of all the cold or hot air in the casing is adjustable, thus ensuring that the cold and hot circulation fan system of the containerized energy storage power station controlled by artificial intelligence is the most economical and optimal overall.

[0033] The above are preferred embodiments of this invention application, and their innovative significance is obvious. Unexpectedly, this invention application not only provides a method for heating or dissipating heat inside a container, but also a concrete, implementable product. Its embodiments highlight the content achievable by the patent application, providing necessary technical details, steps, and technical paths, defining a reasonable scope of protection, achieving technological disclosure, and promoting the dissemination of innovative technology. However, the ability to achieve this is not to require those skilled in the art to implement it without any thought, as this invention application also simultaneously adopts a balance between technological disclosure and corresponding protection to avoid excessive disclosure that could further diminish the value of its innovative technology.

[0034] This specification uses specific examples to illustrate the principles and implementation methods of the present invention, and is intended only to help understand the core ideas of the invention, and should not be construed as limiting the invention. Those skilled in the art will understand that various changes in form and detail made to the invention without departing from the spirit and scope of the invention as defined in the appended specification are within the scope of protection of this invention.
