Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of box-type substations, in particular to a heat dissipation structure of an energy storage box-type substation. BACKGROUND

[0002] An energy storage box-type substation is an important power facility, which usually includes a transformer room, a high-voltage incoming line room, a low-voltage outgoing line room, a communication room, and a fire-fighting room, etc. Various power equipment is installed in these equipment rooms, which will generate a large amount of heat during operation, especially the transformer in the transformer room. In order to ensure the normal operation and service life of the equipment, effective heat dissipation is crucial.

[0003] At present, the common heat dissipation method of the energy storage box-type substation is to open an air inlet on the side of each equipment room and install an exhaust fan on the top of the equipment room. This design uses the exhaust fan to exhaust the hot air in the equipment room, while inhaling the external cold air from the air inlet on the side to achieve the heat dissipation effect.

[0004] However, this traditional heat dissipation structure has obvious defects. Since the air inlet is arranged on the side of the equipment room, it causes the formation of a dead air zone at the lower part of the equipment room, which cannot effectively ventilate and dissipate heat at the lower part of the equipment room. In this case, the temperature distribution in the equipment room is uneven, and the lower area is prone to accumulate heat, which affects the normal operation and service life of the equipment.

[0005] In view of the above problems, the prior art needs to be improved. CONTENT OF THE UTILITY MODEL

[0006] The purpose of the present application is to provide a heat dissipation structure of an energy storage box-type substation, which can improve the heat dissipation efficiency.

[0007] The present application provides a heat dissipation structure of an energy storage box-type substation, comprising:

[0008] a box body, which comprises a base and an equipment room located on the base; the base comprises a suspended bottom plate and an air chamber located on the lower side of the bottom plate, the air chamber is communicated with the external atmosphere, an air inlet hole is opened on the bottom plate, and the air inlet hole is communicated with the equipment room and the air chamber;

[0009] an exhaust system, which is arranged at the upper part of the box body and is used for pumping the air in the equipment room to the outside.

[0010] By arranging the air chamber and the air inlet hole on the base, air is taken in from the bottom, which solves the problem of the dead air zone at the lower part of the equipment room. At the same time, the hot air is exhausted from the upper part by the exhaust system, forming a good air circulation, improving the temperature distribution uniformity in the equipment room, and improving the heat dissipation efficiency.

[0011] Preferably, the equipment room includes a transformer room, a high-voltage incoming line room, a low-voltage outgoing line room, a communication room, and a fire protection room, and the base plate is provided with a plurality of air inlets corresponding to the positions of the transformer room, the high-voltage incoming line room, the low-voltage outgoing line room, the communication room, and the fire protection room;

[0012] The upper parts of the transformer room, the high-voltage incoming line room, the low-voltage outgoing line room, the communication room, and the fire protection room are all connected to the exhaust system.

[0013] Preferably, an annular airflow guide plate is provided in the middle of the inner wall of the transformer chamber, the outer edge of the airflow guide plate is connected to the inner wall of the transformer chamber, and the inner edge forms a passage for the transformer to pass through.

[0014] The function of the airflow guide plate is to guide airflow, allowing air inside the transformer chamber to flow from bottom to top along the transformer windings. This narrows the airflow path, increases the airflow velocity, and thus efficiently removes heat from the transformer windings and core, improving heat dissipation. Furthermore, the airflow guide plate effectively prevents hot air from flowing back to the lower part of the transformer chamber, preventing the formation of a top-to-bottom hot air circulation that could negatively impact heat dissipation efficiency.

[0015] Optionally, the airflow guide plate is composed of multiple sub-plates spliced ​​together.

[0016] Optionally, the airflow guide plate is a one-piece molded structure.

[0017] Optionally, the exhaust system includes multiple exhaust fans; each of the equipment rooms has at least one fan hole at its upper part, and each fan hole is equipped with one exhaust fan, which is used to draw air from the corresponding equipment room to the outside.

[0018] Optionally, the exhaust system includes multiple exhaust fans; at least one fan hole is provided in the upper part of the transformer room; the upper part of the high-voltage inlet room is connected to the transformer room through a first vent; at least one fan hole is provided in the upper part of one of the low-voltage outlet room, the communication room, and the fire room; and the upper parts of the low-voltage outlet room, the communication room, and the fire room are interconnected through a second vent; each fan hole is equipped with one exhaust fan; the exhaust fan is used to draw air from the corresponding equipment room to the outside.

[0019] Preferably, the exhaust fan is fitted with an air guide shroud on the exhaust side, and the outlet of the air guide shroud is set downward.

[0020] By installing a guide hood on the exhaust side of the exhaust fan and setting the outlet of the guide hood downwards, the exhaust hot air can be effectively guided downwards, preventing hot air from lingering in the equipment room and enhancing the overall heat dissipation effect. In addition, it can provide reliable protection for the exhaust fan and fan opening, preventing rainwater or other debris from entering the exhaust fan and equipment room.

[0021] Preferably, the outlet of the air guide shroud is provided with an insect-proof net.

[0022] Preferably, the air chamber has a plurality of openings for connecting to the outside atmosphere, and a filter device is provided at each opening.

[0023] Beneficial effects: The heat dissipation structure of the energy storage box substation provided in this application achieves air intake from the bottom by setting an air chamber and air inlet in the base, which solves the problem of dead airflow in the lower part of the equipment room. At the same time, hot air is discharged from the top through the exhaust system, forming a good airflow circulation, improving the uniformity of temperature distribution in the equipment room and improving heat dissipation efficiency.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0030] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] Energy storage prefabricated substations typically include a transformer room, a high-voltage incoming line room, a low-voltage outgoing line room, a communication room, and a fire protection room. Each room houses different equipment that generates heat during operation, especially the transformer in the transformer room, which produces the most heat and requires cooling. Existing energy storage prefabricated substations generally use air inlets on the sides of each equipment room and exhaust fans at the top. These fans expel hot air from the equipment room and draw in cool outside air through the inlets, thus achieving cooling. However, this cooling structure, by placing the air inlets on the sides of the equipment room, creates dead zones in the lower part of the room, resulting in ineffective ventilation and cooling performance. Therefore, existing technology needs improvement.

[0032] Therefore, please refer to Figures 1-4 A heat dissipation structure for an energy storage box-type substation, as described in some embodiments of this application, includes:

[0033] The housing 1 includes a base 2 and an equipment chamber 3 located on the base 2; the base 2 includes a suspended bottom plate 201 and an air chamber 202 located on the lower side of the bottom plate 201, the air chamber 202 is connected to the outside atmosphere, and an air inlet 203 is provided on the bottom plate 201, the air inlet 203 is connected to the equipment chamber 3 and the air chamber 202.

[0034] An exhaust system is installed at the top of the housing 1 and is used to draw air from the equipment chamber 3 to the outside.

[0035] The heat dissipation structure of this energy storage box-type substation firstly features a suspended base plate 201, beneath which an air chamber 202 is installed, allowing the air chamber 202 to connect with the external atmosphere. Then, air inlets 203 are created on the base plate 201, forming an airflow channel between the air chamber 202 and the equipment chamber 3. Finally, an exhaust system is installed on the upper part of the enclosure 1 to expel hot air from the equipment chamber 3. In this way, cool air can enter the equipment chamber 3 through the air inlets 203 on the base plate 201, while hot air is exhausted through the exhaust system, thus achieving good ventilation within the equipment chamber 3, particularly solving the ventilation and heat dissipation problem in the lower part of the equipment chamber 3, thereby improving heat dissipation efficiency.

[0036] In some implementations, see Figure 1 , Figure 3 The equipment room 3 includes a transformer room 301, a high-voltage inlet room 302, a low-voltage outlet room 303, a communication room 304, and a fire room 305. Multiple air inlets 203 are provided on the base plate 201 at positions corresponding to the transformer room 301, the high-voltage inlet room 302, the low-voltage outlet room 303, the communication room 304, and the fire room 305.

[0037] The upper parts of the transformer room 301, high-voltage incoming line room 302, low-voltage outgoing line room 303, communication room 304 and fire room 305 are all connected to the exhaust system.

[0038] Among them, transformer room 301 is used to install transformers, communication room 304 is used to install communication equipment for communication with external devices, fire room 305 is used to install fire monitoring equipment, high voltage incoming line room 302 is used to install high voltage cabinets, and low voltage outgoing line room 303 is used to install low voltage outgoing line cabinets.

[0039] In some preferred embodiments, see Figure 1 , Figure 2 , Figure 4 An annular airflow guide plate 306 is provided in the middle of the inner wall of the transformer chamber 301. The outer edge of the airflow guide plate 306 is connected to the inner wall of the transformer chamber 301, and the inner edge forms a passage for the transformer to pass through.

[0040] Because transformers generate a significant amount of heat during operation, effective heat dissipation is necessary. The airflow guide plate 306 serves to guide airflow, allowing air within the transformer chamber 301 to flow from bottom to top along the transformer windings. This narrows the airflow path, increases airflow velocity, and efficiently removes heat from the transformer windings and core, improving heat dissipation. Furthermore, the airflow guide plate 306 effectively prevents hot air from flowing back to the lower part of the transformer chamber 301, preventing the formation of a top-to-bottom hot air circulation within the chamber that could negatively impact heat dissipation efficiency.

[0041] There are several ways to achieve the annular structure of the airflow guide plate 306.

[0042] For example, in some possible implementations, see Figure 4 The airflow guide plate 306 is composed of multiple sub-plates spliced ​​together.

[0043] With this design, the airflow guide plate 306 can better adapt to the shape and structure of the inner wall of the transformer chamber 301, ensuring that the airflow guide plate 306 can effectively guide the airflow and avoid uneven heat dissipation caused by the mismatch of a single integral structure.

[0044] The airflow guide plate 306 is composed of multiple sub-plates, which can be assembled in various ways, such as by bolting, snap-fitting, or welding. The shape and size of each sub-plate can be customized according to the specific structure of the inner wall of the transformer chamber 301 to ensure that the assembled airflow guide plate 306 fits tightly against the inner wall of the transformer chamber 301. In addition, the joints between the sub-plates can be sealed with sealing strips or sealant to prevent airflow leakage and improve the airflow guiding effect of the airflow guide plate 306.

[0045] Or, for example, in some other possible implementations, the airflow guide plate 306 is a one-piece molded structure.

[0046] By adopting an integrally molded airflow guide plate 306, the overall strength and stability of the airflow guide plate 306 can be improved, avoiding the gap problems that may be caused by splicing structures, thereby achieving a more efficient airflow guiding effect, ensuring that the airflow in the transformer room 301 can be smoothly guided, and thus improving the heat dissipation effect.

[0047] The one-piece molded airflow guide plate 306 can be manufactured using a single-step molding process, avoiding errors and structural defects that may occur in traditional splicing processes. Specifically, the one-piece molded airflow guide plate 306 can be manufactured using various processes such as injection molding, die casting, or 3D printing. This significantly improves the integrity and precision of the airflow guide plate 306, ensuring the continuity and uniformity of airflow guidance. Furthermore, the one-piece structure can be customized according to the specific dimensions and shape of the transformer chamber 301, further optimizing the airflow guidance effect.

[0048] There are several ways to implement an exhaust system.

[0049] For example, in some embodiments, the exhaust system includes a plurality of exhaust fans 4; each equipment room 3 has at least one fan hole 307 on its upper part, and an exhaust fan 4 is installed on each fan hole 307. The exhaust fan 4 is used to draw the air of the corresponding equipment room 3 to the outside.

[0050] The exhaust system consists of multiple exhaust fans 4, which are installed on the fan openings 307 at the top of each equipment chamber 3. The function of the exhaust fans 4 is to effectively draw air from each equipment chamber 3 to the outside. In this way, hot air in each equipment chamber 3 can be discharged in a timely manner, thereby avoiding heat accumulation and improving the heat dissipation effect of the equipment.

[0051] The arrangement of fan vents 307 can be adjusted according to the specific layout and requirements of the equipment room 3. For example, due to the large heat generation in the transformer room 301, multiple fan vents 307 can be installed to enhance the exhaust effect. The selection of the exhaust fan 4 can be based on the volume of the equipment room 3 and the ventilation requirements to ensure effective air circulation.

[0052] Or, for example, in other embodiments, the exhaust system includes multiple exhaust fans 4; at least one fan hole 307 is provided in the upper part of the transformer room 301; the upper part of the high-voltage inlet room 302 is connected to the transformer room 301 through a first vent 308; at least one fan hole 307 is provided in the upper part of one of the low-voltage outlet room 303, communication room 304, and fire room 305; and the upper parts of the low-voltage outlet room 303, communication room 304, and fire room 305 are interconnected through a second vent 309; each fan hole 307 is equipped with an exhaust fan 4, and the exhaust fan 4 is used to draw air from the corresponding equipment room 3 to the outside (e.g., Figure 1 , Figure 2 (As shown).

[0053] This structure allows the hot air in each equipment room 3 to be effectively discharged through the exhaust fan 4, thus solving the problem of hot air discharge in each equipment room 3 in the energy storage box substation. It can also reduce the number of exhaust fans 4, reduce equipment costs, and improve the reliability of the exhaust system (the fewer the number of devices, the lower the probability of system failure, and thus the more reliable).

[0054] Furthermore, the exhaust fan 4 in the exhaust system can be of various types, such as axial flow fans and centrifugal fans, to adapt to different exhaust requirements. The number and position of the fan holes 307 can be optimized according to the specific layout and heat distribution of the equipment chamber 3. The size and position of the first vent 308 and the second vent 309 can also be adjusted according to actual needs to ensure smooth airflow between the equipment chambers 3. In addition, the control system of the exhaust fan 4 can be connected to the temperature sensor in the equipment chamber 3 to automatically adjust the operating power of the exhaust fan 4 according to temperature changes, thereby improving exhaust efficiency.

[0055] For example, in this embodiment, the transformer room 301 has four fan holes 307 on its upper part, and the low-voltage outgoing line room 303 has two fan holes 307 on its upper part. The low-voltage outgoing line room 303 is connected to the communication room 304, and the communication room 304 is connected to the fire room 305 through the second ventilation hole 309 (e.g., Figure 1 (as shown), but not limited to this.

[0056] Preferably, see Figure 1 Each exhaust fan 4 is fitted with an air guide shroud 5 on its exhaust side, with the outlet of the air guide shroud 5 facing downwards.

[0057] By setting up the air guide shroud 5, the airflow guidance problem on the exhaust side of the exhaust fan 4 is effectively solved, ensuring that the exhaust hot air can be discharged downwards in an orderly manner, avoiding the formation of turbulence, thereby improving the heat dissipation efficiency in the equipment room 3. By setting the air guide shroud 5 on the exhaust side of the exhaust fan 4 and setting the outlet of the air guide shroud 5 downwards, the exhaust hot air can be effectively guided to flow downwards, avoiding the hot air from stagnating in the equipment room 3, thus enhancing the overall heat dissipation effect; in addition, it can provide reliable protection for the exhaust fan 4 and the fan hole 307, preventing rainwater or other debris from entering the exhaust fan 4 and the equipment room 3.

[0058] The air guide shroud 5 can be made of various materials, such as metal, plastic, or composite materials, and the specific choice can be adjusted according to the needs of the actual application environment. The shape of the air guide shroud 5 can be circular, square, or other shapes to accommodate different types of exhaust fans 4. The dimensions of the air guide shroud 5 should be designed according to the specifications of the exhaust fan 4 to ensure that it completely covers the exhaust fan 4's outlet side and the fan hole 307. The air guide shroud 5 can be installed using various methods such as bolt fixing, clip fixing, or welding to ensure that it will not fall off or shift during operation.

[0059] Each exhaust fan 4 can be equipped with a corresponding air guide shroud 5, or multiple exhaust fans 4 can share one air guide shroud 5.

[0060] Furthermore, an insect-proof net can be installed at the outlet of the air guide shroud 5. The function of the insect-proof net is to prevent external insects from entering the equipment room 3 through the outlet of the air guide shroud 5, thereby protecting the equipment inside the equipment room 3 and ensuring its normal operation. By installing an insect-proof net at the outlet of the air guide shroud 5, the entry of external insects into the equipment room 3 can be effectively blocked, solving the technical problem of insects potentially entering the equipment room 3 and ensuring the safe operation of the equipment.

[0061] An insect-proof net is installed at the outlet of the air guide shroud 5, which can be implemented in various ways. For example, the insect-proof net can be made of metal mesh or durable plastic mesh, with mesh sizes small enough to block insects from entering while ensuring smooth airflow. The insect-proof net can be fixed to the outlet of the air guide shroud 5 by means of adhesive, clips, or screws. As a preferred embodiment, the insect-proof net can be designed as a detachable structure for easy cleaning and replacement. Furthermore, an insect repellent can be applied to the insect-proof net to enhance its insect-proof effect.

[0062] In some implementations, see Figure 2 Figure 1 The air chamber 202 has several connecting ports 204 for connecting to the outside atmosphere, and a filter device 6 is provided at each connecting port 204.

[0063] The air chamber 202 is connected to the outside atmosphere through these connecting ports 204. The function of the filter device 6 is to prevent impurities in the outside air from entering the air chamber 202, thereby ensuring the cleanliness of the air inside the air chamber 202. By installing the filter device 6 at the connecting ports 204, the problem of impurities entering when the air chamber 202 is connected to the outside atmosphere is solved, ensuring the cleanliness of the air inside the air chamber 202, and thus improving the operating efficiency and reliability of the entire energy storage box-type substation's heat dissipation structure.

[0064] The filter device 6 can take various forms; for example, it can use materials such as filter screens, filter cotton, or filter cartridges to achieve the filtration function. Filter screens can be made of metal or plastic mesh, offering good durability and easy cleaning. Filter cotton can be made of high-efficiency filter cotton, providing good filtration performance and a long service life. Filter cartridges can have a multi-layer structure to further improve filtration efficiency. Furthermore, the filter device 6 can be designed with a detachable structure for easy replacement and maintenance.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
