Description

Technical Field

[0001] This utility model relates to the field of energy storage converter technology, specifically to a protective energy storage converter module device based on an energy storage system. Background Technology

[0002] In today's power energy storage systems, the heat dissipation, protection, and vibration damping design of energy storage converter modules are key factors in ensuring their efficient operation and stable reliability.

[0003] Traditional converter modules often employ integrated heat dissipation structures, such as overall air cooling or liquid cooling designs. While these structures are simple, they have several technical drawbacks. For example, overall air cooling structures are not effective enough in dealing with localized high temperatures, potentially causing localized temperatures to exceed 85°C and accelerating the aging of critical components such as IGBTs.

[0004] Existing improvement solutions (such as a long-life, low-failure intelligent electrical control cabinet with patent publication number CN112821256A) improve overall heat dissipation capacity by increasing the number of cooling fans or optimizing the air duct layout, but cannot dynamically respond to local temperature rises.

[0005] Furthermore, the traditional method of welding heat sink fins to the substrate makes cleaning or replacement work complicated and costly.

[0006] Therefore, we propose a protective energy storage converter module device based on an energy storage system to solve the problems mentioned above. Utility Model Content

[0007] The purpose of this utility model is to provide a protective energy storage converter module device based on an energy storage system, so as to solve the problem that the existing energy storage converter module adopts an overall air-cooled heat dissipation structure, which is not effective enough in dealing with local high temperature problems, and may cause excessive local temperature, accelerating the aging of key components such as IGBT.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] A protective energy storage converter module device based on an energy storage system includes a protective housing. Inside the protective housing are a split-type heat dissipation unit and a detection-type heat dissipation unit. The split-type heat dissipation unit consists of a copper substrate, a detachable heat dissipation fin assembly, and an independent air duct. The copper substrate is connected to the IGBT module via a planar bonding, and the heat dissipation fin assembly is detachably fixed to both sides of the copper substrate. The detection-type heat dissipation unit is installed on the side of the protective housing away from the heat dissipation fin assembly. The detection-type heat dissipation unit is used to detect and centrally cool the high-temperature electronic components on the energy storage converter module.

[0010] Preferably, the copper substrate has detachable slots on both sides, and magnetic plates are installed inside the slots.

[0011] Preferably, the heat dissipation fin assembly includes flow guide fins and a connecting plate. There are several flow guide fins arranged in parallel, and the connecting plate fixes all the flow guide fins. One side of the flow guide fins is attached to the copper substrate for heat conduction.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0013] This utility model's energy storage converter module provides comprehensive physical protection through a protective shell, ensuring that internal electronic components are not subject to physical damage or environmental factors. The copper substrate in the split-type heat dissipation unit is directly attached to the IGBT module, efficiently absorbing the heat it generates. The detachable heat dissipation fins are quickly installed or removed via magnetic adsorption, improving heat dissipation efficiency and facilitating maintenance and cleaning. The detection-type heat dissipation unit includes a thermal imaging sensor and a high-speed cooling fan, which monitors and accurately locates high-temperature areas in real time, and uses a displacement component to quickly move the fan for targeted forced cooling. Multiple guide fins of the heat dissipation fins are fixed by connecting plates, forming independent air ducts, improving cold air circulation efficiency and reducing airflow short-circuiting. The protective shell adopts a three-layer composite structure: the outer frame provides mechanical strength, the middle sealing layer prevents moisture and dust intrusion, and the inner isolation plate is made of flame-retardant and fire-resistant material to prevent the spread of high temperatures or electric arcs. A detachable dust filter is installed at the bottom air inlet, and an inclined guide plate is installed at the top exhaust outlet, forming a bottom-up directional airflow that efficiently removes heat. The split-type heat dissipation unit efficiently dissipates heat and dynamically responds to local temperature rises when needed, while the detection-type heat dissipation unit accurately monitors and quickly dissipates heat, together improving the stability and long-term operating efficiency of the energy storage converter module.

[0020] 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.

[0021] Example 1:

[0022] Please see Figure 1-5 This utility model provides a technical solution:

[0023] A protective energy storage converter module device based on an energy storage system includes a protective housing 1. Inside the protective housing 1, there are a split-type heat dissipation unit 2 and a detection-type heat dissipation unit 3. The split-type heat dissipation unit 2 consists of a copper substrate 4, a detachable heat dissipation fin assembly 5, and an independent air duct 6. The copper substrate 4 is connected to the IGBT module 7 by planar bonding. The heat dissipation fin assembly is detachably fixed to both sides of the copper substrate 4. The detection-type heat dissipation unit 3 is installed on the side of the protective housing 1 away from the heat dissipation fin assembly. The detection-type heat dissipation unit 3 is used to detect and centrally cool the high-temperature electronic components on the energy storage converter module.

[0024] In the above scheme, the energy storage converter module is provided with overall protection by the protective housing 1. The internally installed split-type heat dissipation unit 2 is specifically designed for efficient heat dissipation of the IGBT module 7. Its copper substrate 4 is directly attached to the IGBT module 7 to absorb heat, and heat dissipation is enhanced by a detachable heat dissipation fin assembly 5. An independent air duct 6 ensures directional airflow and avoids hot air stagnation. The detection-type heat dissipation unit 3 is installed on the other side of the housing. It monitors and dynamically adjusts local high-temperature areas through thermal imaging to compensate for the shortcomings of traditional overall heat dissipation. The two work together to ensure stable heat dissipation of the main heat-generating components and flexibly cope with random temperature rise problems, thereby improving the overall heat dissipation efficiency and reliability.

[0025] The copper substrate 4 has detachable slots 8 on both sides, and magnetic plates 9 are installed inside the slots 8.

[0026] The above solution allows for quick installation and removal of the heat sink fin assembly via magnetic adsorption, eliminating the need for additional fasteners and facilitating maintenance or replacement. The magnetic design ensures a tight fit between the thermally conductive contact surfaces, reducing thermal resistance, while the mechanical locking mechanism of slot 8 prevents fin assembly displacement, ensuring long-term operational stability.

[0027] Furthermore, the heat dissipation fin assembly includes flow-guiding fins 10 and a connecting plate 11. Several flow-guiding fins 10 are arranged in parallel, and the connecting plate 11 fixes all the flow-guiding fins 10. One side of each flow-guiding fin 10 is attached to the copper substrate 4 for heat conduction. Both ends of the connecting plate 11 are provided with retaining plates 12, which cooperate with the slots 8. The retaining plates 12 are made of a magnetic material that attracts the magnetic plate 9.

[0028] The heat dissipation fin assembly consists of multiple parallel airflow guiding fins 10 fixed together by a connecting plate 11. One side of the airflow guiding fins 10 is in close contact with the copper substrate 4 to conduct heat. The connecting plate 11 has retaining plates 12 at both ends. The retaining plates 12 are made of magnetic material and cooperate with the magnetic suction plates 9 in the slots 8 of the copper substrate 4 for adsorption and fixation. This modular design ensures a secure installation of the fin assembly, optimizes the airflow channel, allows cool air to pass evenly through the fin gaps, improving heat dissipation efficiency, and facilitates disassembly, cleaning, or replacement.

[0029] The detection-type heat dissipation unit 3 includes a thermal imaging sensor 13 and a high-speed heat dissipation fan 14. Two sets of thermal imaging sensors 13 are provided and distributed at both ends inside the protective housing 1. The protective housing 1 is equipped with a displacement component that drives the high-speed heat dissipation fan 14 to move. The displacement component includes a first drive rail 16 that drives the high-speed heat dissipation fan 14 to move laterally, and a second drive rail 17 that drives the first drive rail 16 to move longitudinally.

[0030] In the above scheme, the detection-type heat dissipation unit 3 includes two sets of thermal imaging sensors 13 and a high-speed cooling fan 14. The sensors are distributed at both ends of the housing to scan the internal temperature distribution in real time. The fan achieves lateral and longitudinal movement through a displacement component to accurately locate high-temperature points. The first guide rail controls the lateral displacement, and the second guide rail drives the entire lateral mechanism to move longitudinally, forming a two-dimensional plane coverage, ensuring that the fan can quickly respond to temperature rises at any location and provide targeted forced heat dissipation.

[0031] A temperature sensor 18 is located on the side of the high-speed cooling fan 14 closest to the IGBT module 7. The temperature sensor 18 is used to measure the temperature of the electronic components of the energy storage converter module in real time. An air inlet cover 19 is fixedly connected to the side of the high-speed cooling fan 14 away from the IGBT module 7. A flexible air duct 20 is fixedly connected to the side of the air inlet cover 19. The other end of the flexible air duct 20 is connected to the outside of the protective housing 1.

[0032] Furthermore, a temperature sensor 18 is installed on the outlet side of the high-speed cooling fan 14 to monitor the temperature of the target component in real time and adjust the fan speed accordingly. The fan inlet side is connected to an inlet cover 19, which is directly connected to the external environment via a flexible duct 20, ensuring that cool air is drawn in rather than hot internal air, thus preventing airflow short-circuiting. This design forms an independent local cooling airflow path, improving heat dissipation efficiency while reducing interference with the overall airflow.

[0033] The protective housing 1 includes an outer frame 21, an intermediate sealing layer 22, and an inner isolation plate 23. The intermediate sealing layer 22 covers the seams of the outer shell, and the inner isolation plate 23 is a flame-retardant fireproof board.

[0034] In the above scheme, the protective shell 1 adopts a three-layer composite structure. The outer frame 21 provides mechanical strength, the middle sealing layer 22 covers the seams to prevent moisture or dust from entering, and the inner isolation plate 23 is made of flame-retardant and fireproof material to prevent the spread of internal high temperature or electric arc. The layered design takes into account both protection level and safety, and solves the problems of insufficient sealing or poor fire resistance of traditional shells.

[0035] Furthermore, the independent air duct 6 of the split heat dissipation unit 2 consists of a bottom air inlet 24 and a top air outlet 25. The air inlet is equipped with a removable dust filter 26, and the air outlet is equipped with an outwardly inclined guide plate 27. The guide plate 27 forms an acute angle with the plane of the air outlet to prevent external airflow from flowing back.

[0036] The independent air duct 6 of the split-type heat dissipation unit 2 consists of a bottom air inlet 24 and a top air outlet 25. The air inlet is equipped with a removable dust filter 26 to prevent dust accumulation, and the air outlet is equipped with an inclined guide plate 27, whose sharp angle design guides hot air outward and prevents external airflow from interfering with the internal air duct. This structure forms a bottom-up directional airflow, efficiently removing heat from the heat dissipation fins and avoiding the uneven heat dissipation problem caused by turbulent airflow in traditional air ducts.

[0037] Although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these specific embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
