Technical Field
[0001] This utility model belongs to the field of temperature control technology for energy storage equipment, and specifically relates to a thermal management device for an integrated energy storage cabinet. Background Technology
[0002] Thermal management equipment for integrated energy storage cabinets refers to a series of devices, components, and systems specifically designed for integrated energy storage cabinets. These devices regulate environmental parameters such as temperature and humidity within the cabinet through active or passive means, maintaining the energy storage system under suitable operating conditions. The core objective is to avoid performance degradation, shortened lifespan, or even thermal runaway and fire risks caused by excessive heat, excessive cold, excessive local temperature differences, or excessive humidity in energy storage units through efficient heat management and control of environmental humidity. At the same time, it also takes into account the needs of energy consumption optimization and intelligent operation and maintenance. It is a key supporting device to ensure the safe, stable, and efficient operation of integrated energy storage cabinets.
[0003] However, although the thermal management equipment of the energy storage integrated cabinet can achieve overall temperature control, due to the large differences in the working principles and power of different equipment in the cabinet, the heat dissipation is significantly uneven. Existing devices often cannot achieve precise and rapid directional heat dissipation for local high-temperature equipment, which leads to the accumulation of temperature in some high-heat components. This, to a certain extent, limits the adaptability and operational safety of the equipment under high power density and complex operating conditions.
[0004] To address the aforementioned issues, this application proposes an integrated energy storage cabinet thermal management device. Utility Model Content

A connecting pipe is fixedly connected to the inner wall of the sliding frame. An exhaust fan is fixedly connected to the inner wall of the connecting pipe.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: By setting up a collaborative architecture of a dynamically adjustable targeted heat dissipation mechanism and a global temperature control system, the problem of insufficient local heat dissipation capacity of traditional equipment is effectively solved. With the help of multiple sets of temperature sensors in the area separated by the isolation frame, the temperature difference between different devices can be captured in real time and the high temperature point can be located, breaking through the local temperature difference blind zone in the overall temperature control mode. With the sliding frame driven by the brake motor and threaded rod, the exhaust frame can be moved up and down along the slot frame, so that the exhaust fan can perform directional heat extraction to the high temperature area through the connecting pipe, achieving precise adaptation of the heat dissipation path. At the same time, the basic refrigeration network formed by the refrigeration unit and the refrigeration pipe frame, together with the directional exhaust system, forms a layered heat dissipation mode.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0017] Please see Figure 1-8 The present invention provides the following technical solution: a thermal management device for an integrated energy storage cabinet, comprising an energy storage cabinet 1, a controller 6 and a refrigeration unit 8 respectively arranged on the front of the energy storage cabinet 1, a refrigeration pipe rack 11 arranged inside the energy storage cabinet 1, the output end of the refrigeration unit 8 passing through the energy storage cabinet 1 and fixedly connected to the outer surface of the refrigeration pipe rack 11, an isolation frame 10 fixedly connected to the inner wall of the energy storage cabinet 1, two sets of support frames 12 fixedly connected to the inner wall of the isolation frame 10, a temperature sensor 13 arranged above each support frame 12, an exhaust frame 16 arranged inside the energy storage cabinet 1, and a slot frame 18 fixedly connected to the right side of the energy storage cabinet 1; The inner wall of the slot frame 18 is rotatably connected to two threaded rods 22. Two brake motors 19 are installed above the slot frame 18. The power output end of each brake motor 19 is fixedly connected to the top of the threaded rod 22. A sliding frame 21 is slidably connected inside the slot frame 18. The inner wall of the sliding frame 21 is threadedly connected to the outer surface of the threaded rod 22. A connecting pipe 17 is fixedly connected to the inner wall of the sliding frame 21. An exhaust fan 23 is fixedly connected to the inner wall of the connecting pipe 17. The left end of the connecting pipe 17 is fixedly connected to the right side of the exhaust frame 16. In this embodiment, the controller 6 adopts a programmable logic controller (PLC), which is a digital computing and operating electronic system designed specifically for industrial environments. Its core components include a programmable CPU, memory, input / output interface circuits, and power supply. It can store user instructions through the programmable memory to realize functions such as logic operations, sequential control, timing, counting, and arithmetic operations. It can also use digital input / output modules to precisely control various machines or production processes. Meanwhile, the refrigeration unit 8 is mainly composed of a compressor, condenser, throttling device, and evaporator, providing core support for the temperature control function of the device.
[0018] Specifically, the bottom surface of the energy storage cabinet 1 is fixedly connected to two sets of connecting columns 2, and the bottom end of each connecting column 2 is fixedly connected to a support base 3. In this embodiment, the energy storage cabinet 1 is raised to a certain height by the cooperation of the connecting columns 2 and the support base 3. This avoids the problem of moisture caused by the bottom of the cabinet directly contacting the ground, and increases the contact area with the ground through the support base 3, thereby improving the stability of the equipment when it is placed. At the same time, it provides ventilation space for the bottom of the cabinet to help dissipate heat inside the cabinet.
[0019] Specifically, the left side of the energy storage cabinet 1 is hinged with a connecting door 4, and the left side of the connecting door 4 is provided with equidistantly arranged ventilation openings 5. In this embodiment, the connecting door 4 realizes the closed protection and convenient maintenance of the internal equipment of the energy storage cabinet 1, while the ventilation openings 5 can form an air convection channel when the equipment is running, and accelerate the air circulation in conjunction with the cabinet exhaust component, so as to exhaust the heat inside the cabinet through the ventilation openings 5, while preventing a large amount of external dust from directly entering the cabinet.
[0020] Specifically, a connecting plate 7 is fixedly connected to the back of the controller 6. The back of the connecting plate 7 is fixedly connected to the front of the energy storage cabinet 1. In this embodiment, the controller 6 is securely installed on the front of the energy storage cabinet 1 by the connecting plate 7, which not only ensures the reliable connection between the controller 6 and the cabinet and prevents the equipment from loosening due to vibration during operation, but also creates a certain distance between the controller 6 and the surface of the cabinet, reducing the direct conduction of heat from the cabinet to the controller 6 and ensuring its operational stability.
[0021] Specifically, a support plate 9 is fixedly connected to the bottom surface of the refrigeration unit 8. The back of the support plate 9 is fixedly connected to the front of the energy storage cabinet 1. In this embodiment, the support plate 9 provides stable support for the refrigeration unit 8, disperses the vibration load generated by the refrigeration unit 8 during operation, avoids loosening of the connection parts due to long-term vibration, and raises the installation height of the refrigeration unit 8 to facilitate heat dissipation at its bottom and pipeline inspection and maintenance.
[0022] Specifically, a support ring 14 is fixedly connected to the bottom surface of each temperature sensor 13, and the bottom surface of each support ring 14 is fixedly connected to the upper surface of the support frame 12. In this embodiment, the temperature sensor 13 is precisely fixed at a preset height above the support frame 12 by the support ring 14, ensuring that the sensor detection end maintains the best sensing distance with the heating device, thereby improving the accuracy of temperature detection. At the same time, the temperature sensor 13 is a device that can convert the physical quantity of temperature into an electrical signal that can be measured and processed.
[0023] Specifically, two fixing brackets 15 are fixedly connected to the outer surface of the refrigeration tube rack 11. The two fixing brackets 15 are respectively fixedly connected to the inner top wall and inner bottom wall of the energy storage cabinet 1 on opposite sides. In this embodiment, the refrigeration tube rack 11 is stably suspended inside the energy storage cabinet 1 by the fixing brackets 15, which ensures that the installation position of the refrigeration tube rack 11 in the cabinet is accurate and stable, avoids leakage at the connection point due to pipe shaking during coolant circulation, and at the same time maintains a reasonable distance between the refrigeration tube rack 11 and the cabinet to improve heat exchange efficiency.
[0024] Specifically, each brake motor 19 has a connecting seat 20 fixedly connected to its left side, and the bottom surface of each connecting seat 20 is fixedly connected to the upper surface of the energy storage cabinet 1. In this embodiment, the brake motor 19 is firmly installed on the top of the energy storage cabinet 1 through the connecting seat 20 to ensure the coaxiality and stability of the motor during operation and to prevent the threaded rod 22 from shifting due to vibration. At the same time, the brake motor 19 is a special motor that integrates a braking device. It adds a mechanical braking mechanism to the ordinary drive motor, which can quickly apply braking force to the motor shaft when the motor stops running, so that the motor output shaft is braked immediately and kept stationary, preventing the shaft from rotating due to load gravity or inertia.
[0025] The working principle and usage process of this utility model are as follows: First, perform initialization checks and parameter settings on the equipment. Confirm that the connecting column 2 and support base 3 at the bottom of the energy storage cabinet 1 are placed stably. Check that the connecting door 4 is tightly closed and that the ventilation opening 5 is not blocked. Check that the pipe connections between the refrigeration unit 8 and the refrigeration pipe rack 11 are secure. Ensure that the temperature sensor 13 is stably fixed to the support rack 12 via the support ring 14, and that the sensing end is unobstructed. Then, connect the power supply. Set the internal temperature threshold through the operating interface of the controller 6, and configure heat dissipation linkage parameters such as the starting speed of the exhaust fan 23 and the moving speed of the brake motor 19. After the equipment starts, it enters automatic operation. In each area of the isolation rack 10, the temperature sensor 13 converts the collected temperature signal into an electrical signal and transmits it to the controller 6 in real time. The controller 6 analyzes the data and accurately locates the high-temperature area. When the temperature of a certain area reaches the trigger threshold, the controller 6 immediately drives the corresponding area's heat dissipation mechanism. On one hand, it controls the brake motor 19 to start, driving the threaded rod 22 to rotate, causing the sliding rack 21 to move along the groove rack 1. 8. Slide the exhaust fan 16 up and down to position it directly in front of the high-temperature area. Simultaneously, the exhaust fan 23 starts and extracts the accumulated heat through the connecting pipe 17. Outside cold air enters the cabinet through the ventilation opening 5, forming convection with the exhaust fan 23 to accelerate heat dissipation and achieve targeted local heat dissipation. On the other hand, the refrigeration unit 8 delivers low-temperature refrigerant to the refrigeration pipe rack 11 through components such as the compressor and condenser. With the help of the stable pipe rack structure of the fixed frame 15, heat exchange occurs with the air inside the cabinet, maintaining a stable overall ambient temperature. When the temperature drops to a safe range, the controller 6 issues a command to stop the exhaust fan 23. The brake motor 19 locks the threaded rod 22 through the built-in braking mechanism, keeping the exhaust fan 16 in its current position or resetting it, reducing energy consumption. If shutdown or maintenance is required, the internal components can be inspected by opening the connecting door 4, such as cleaning the dust in the ventilation opening 5 and calibrating the temperature sensor 13. The entire process is intelligently controlled by the controller 6, achieving on-demand allocation of heat dissipation resources, solving the problem of local high-temperature accumulation, and ensuring the overall stability and energy efficiency of the equipment.
