Description

Technical Field

[0001] This invention relates to the field of energy storage battery box technology, specifically to an energy storage battery box with high heat dissipation performance. Background Technology

[0002] An energy storage battery box is an integrated device for storing electrical energy. It typically integrates battery packs, battery management systems (BMS), power conversion systems (PCS), and safety protection equipment into a box structure. It can achieve flexible storage and on-demand release of electrical energy and is widely used in power systems, renewable energy, emergency power supply and other scenarios. Its core functions include peak shaving and valley filling, frequency and voltage regulation, backup power support, and smoothing the output of unstable energy sources such as photovoltaic and wind power. Conventional energy storage battery boxes integrate multiple battery cells inside, and during charging and discharging, they need to work with heat dissipation components to dissipate the heat generated.

[0003] Application CN220290911U discloses an energy storage battery box. By setting a cooling channel inside the box and setting heat-conducting plates inside the cooling channel, the setting of heat-conducting plates can increase the heat conduction area of ​​the box, making the contact surface between the coolant and the box larger, enabling the coolant to absorb more heat, and making the energy storage battery box have better heat dissipation performance than existing technologies.

[0004] Application CN219457765U discloses a high-performance alloy energy storage battery housing. By using a cooling component in conjunction with a rectangular cooling coil, the large surface area of ​​the rectangular cooling coil can increase the contact area with the base, thereby improving the heat conduction efficiency. The use of Hastelloy material can greatly improve heat dissipation efficiency and performance. By using the cooling component in conjunction with an automatic start-stop component, the cooling unit can be automatically controlled to stop running when the temperature is low, thereby reducing energy demand.

[0005] However, the energy storage battery box with high heat dissipation performance disclosed above still has the following problems in actual use: heat dissipation is achieved by setting heat dissipation fins that are in contact with the battery modules inside the battery box, but the internal space of the existing battery box is limited. In order to maximize the utilization rate, the reserved gap between the installed battery modules is small. Distributing contact heat dissipation fins in the gap will further prevent heat from being discharged. The added water cooling components are difficult to dissipate heat in time, which leads to heat accumulation inside the battery box and affects the normal operation of the battery.

[0006] Therefore, we propose an energy storage battery box with high heat dissipation performance to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide an energy storage battery box with high heat dissipation performance. This invention addresses the problem that existing battery boxes dissipate heat by installing heat dissipation fins inside the battery box that are in contact with the battery modules. However, the internal space of existing battery boxes is limited, and in order to maximize utilization, the gaps between the installed battery modules are small. Distributing contact heat dissipation fins in the gaps further prevents heat from being dissipated. The added water-cooling components are also unable to dissipate heat in a timely manner, which leads to the accumulation of heat inside the battery box and affects the normal operation of the battery.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a high heat dissipation energy storage battery box, comprising a battery box body and a charging / discharging panel fixedly installed on the front of the battery box body; The battery pack contains batteries installed at equal intervals inside, and the charging and discharging of the batteries is controlled by the charging and discharging panel. The battery box body is provided with an air guiding mechanism, which includes a main air guiding frame and a secondary air guiding frame. The main air guiding frame and the secondary air guiding frame are used to guide the flowing air into the battery bodies that are evenly distributed. A heat dissipation mechanism is provided at the rear of the battery box body, and the heat dissipation mechanism includes a heat dissipation fan module and a heat dissipation filter window.

[0009] Preferably, the heat dissipation mechanism includes heat dissipation filters on the left and right sides in front of the battery box body, and the outer walls of the symmetrically arranged heat dissipation filters are fitted with dustproof partitions that slide against each other. The dustproof partitions slide elastically inside the battery box body, and a dust removal brush is provided on the inner wall of the side of the dustproof partition closest to the heat dissipation filter. The dust removal brush is driven by the sliding of the dustproof partition to clean the heat dissipation filter.

[0010] Preferably, the heat dissipation mechanism includes a heat dissipation fan module installed on the left and right rear sides of the battery box body, and a centrifugal slide cylinder is fixedly installed at the front end of the heat dissipation fan module at an equal angle, and a centrifugal slide rod is slidably provided through the outer end of the centrifugal slide cylinder, and the centrifugal slide rod and the centrifugal slide cylinder are connected to each other by a return spring.

[0011] Preferably, the heat dissipation mechanism includes a main magnetic block, which is fixedly connected to the outer end of the centrifugal slide bar. A secondary magnetic block is distributed on the outer side of the main magnetic block, and a guide slide bar is fixedly installed on the outer end of the secondary magnetic block. The outer end of the guide slide bar slides through the outside of the heat dissipation fan module through a contact spring.

[0012] Preferably, the heat dissipation mechanism includes a main magnetic block and a secondary magnetic block that attract each other in a manner of opposite magnetic properties. In the initial state, the main magnetic block is far away from the secondary magnetic block and does not produce a magnetic attraction effect. The end of the guide slide rod at the outer end of the secondary magnetic block is fixedly connected to the rear end of the traction cable. The traction cable passes through the interior of the battery box body and is fixedly connected to the dustproof partition.

[0013] Preferably, the main flow guide mechanism includes a main flow frame that is fixedly installed in an inverted "T" shape at the center of the battery box body. The main flow frame has an internal hollow structure, with its outer ends corresponding to the heat dissipation filters on the left and right sides of the front of the battery box body. The rear end of the main flow frame extends to the heat dissipation fan module.

[0014] Preferably, the flow guiding mechanism includes a flow guiding plate, which is rotatably mounted on the left and right sides of the main flow frame via bearings at equal distances. The flow guiding plates are distributed in the gaps between adjacent battery bodies. A flow guiding gear is fixedly installed at the upper shaft of the flow guiding plate, and a flow guiding rack is meshed with the inner side of the flow guiding gear.

[0015] Preferably, the top surface of the main flow frame included in the flow guiding mechanism is rotatably mounted with a guide screw via a bearing, and the guide screw is threaded through the front end of the flow guiding rack. The rotation of the guide screw drives the flow guiding rack to move, thereby driving the meshing flow guiding gear and the flow guiding plate to rotate, so as to control the amount of heat dissipation airflow in the middle of the main flow frame.

[0016] Preferably, the flow guiding mechanism includes a secondary flow guiding frame that is fixedly installed on the left and right sides inside the battery box body, and the inner side of the secondary flow guiding frame is in close contact with the rear end of the battery body. The secondary flow guiding frame is arranged in a hollow structure, and the front end of the secondary flow guiding frame extends to the inner side of the heat dissipation filter window, while the rear end of the secondary flow guiding frame extends to the front of the heat dissipation fan module. The interior of the secondary flow guiding frame is provided with flow windows at equal intervals.

[0017] Preferably, the flow guiding mechanism includes flow windows that are distributed at the gaps at the outer ends of adjacent battery bodies, and the flow windows and flow guiding plates correspond to each other. They are used to guide the airflow from the outside to the inside to realize the delivery and discharge of hot airflow. A flow guiding plate is fixedly installed on the inner side of the flow window, and the flow guiding plate is distributed in a manner with the front end facing inward and the rear end facing outward. The flow guiding plate guides the airflow to the outside of the battery body.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: This high heat dissipation energy storage battery box opens the heat dissipation filter window through the operation of the heat dissipation module inside the battery box body. While cleaning and isolating dust, it guides the airflow to the interior of the main flow frame and the secondary flow frame. The angle of the flow guide plate is adjusted so that some air flows in the gaps of the battery body. Then, the pressure difference of the flow velocity carries the hot air out of the battery box body, improving the heat dissipation effect. The specific details are as follows: 1. The battery box is installed on the battery body. The charging and discharging operation of the battery body is controlled by the charging and discharging panel on the front of the battery box. At the same time, the heat dissipation fan module installed at the rear of the battery body works, thereby creating a negative pressure inside the battery box, which draws and discharges the heat dissipated by the battery body from the inside to the outside.

[0019] Furthermore, the rotation of the cooling fan module drives the centrifugal slide cylinder. The centrifugal force is greater than the force of the return spring, so that the centrifugal slide rod and the main magnetic block slide outward. The centrifugal slide rod and the auxiliary magnetic block attract each other, which drives the guide slide rod to tension the traction cable. The traction cable drives the fixed dustproof partition to slide backward, thereby opening the heat dissipation filter window. The dust removal brush plate moves with the dustproof partition to clean the dust adsorbed on the surface of the heat dissipation filter window.

[0020] 2. The cooling fan module draws air from inside the battery box and draws air from the corresponding heat dissipation window through the front end of the main flow frame, so that the air flows from front to back inside the main flow frame, thereby achieving heat exchange and dissipation through the evenly distributed battery body.

[0021] Furthermore, the motor operating the main flow frame drives the guide screw threaded to the guide rack. The guide rack moves backward to mesh with the guide gear and the guide plate to rotate, thereby controlling the size of the opening in the middle of the main flow frame so that hot air can be transferred and transported through the airflow difference during the flow of air inside the main flow frame.

[0022] 3. The interior of the secondary airflow guide frame corresponding to the heat dissipation fan module is under negative pressure. Air is drawn in through the heat dissipation filter so that it can flow and be transported from front to back. The guide ramp set inside the front end of the secondary airflow guide frame guides part of the air entering through the heat dissipation filter so that the external airflow can enter the interior of the secondary airflow guide frame and move along the secondary airflow guide frame at the outer end of the battery body.

[0023] Furthermore, the flow-through inclined plate inside the secondary flow-through frame blocks and guides the flowing air outward. Some of the air flows to the gap between adjacent battery bodies, carrying hot air. The rotating flow-through plate opens the main flow-through frame, thereby absorbing the air carrying hot air and discharging it to the outside of the battery box body through the flow velocity difference.

[0026] 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.

[0027] Please see Figures 1-10 The present invention provides the following technical solution: Example 1: To address the problem of poor heat dissipation inside existing energy storage battery boxes, this example discloses the following technical solution: a high-heat-dissipation energy storage battery box, comprising a battery box body 1 and a charging / discharging panel 2 fixedly installed on the front of the battery box body 1; wherein battery bodies 3 are installed at equal intervals inside the battery box body 1, and the charging / discharging of the battery bodies 3 is controlled by the charging / discharging panel 2; a heat dissipation mechanism is provided at the rear of the battery box body 1, and the heat dissipation mechanism includes a heat dissipation fan module 6 and a heat dissipation filter 7; the heat dissipation filter 7 included in the heat dissipation mechanism is opened on the left and right sides at the front of the battery box body 1, and the outer walls of the symmetrically arranged heat dissipation filter 7 are fitted with dust-blocking baffles 8, and the dust-blocking baffles 8 elastically slide inside the battery box body 1, and a dust removal brush 9 is provided on the inner wall of the dust-blocking baffle 8 near the heat dissipation filter 7, and the dust removal brush 9 is driven by the sliding of the dust-blocking baffle 8 to clean the heat dissipation filter 7.

[0028] The heat dissipation mechanism includes a heat dissipation fan module 6 installed on the rear left and right sides of the battery box body 1. A centrifugal slide cylinder 10 is fixedly mounted at an equal angle on the front end of the heat dissipation fan module 6. A centrifugal slide rod 11 is slidably provided through the outer end of the centrifugal slide cylinder 10, and the centrifugal slide rod 11 and the centrifugal slide cylinder 10 are connected to each other by a return spring 12. The heat dissipation mechanism also includes a main magnetic block 13, which is fixedly connected to the outer end of the centrifugal slide rod 11. Secondary magnetic blocks 14 are correspondingly distributed on the outer side of the main magnetic block 13. A guide slide rod 15 is fixedly installed on the outer end of the auxiliary magnetic block 14. At the same time, the outer end of the guide slide rod 15 slides through the outside of the heat dissipation fan module 6 through the contact spring 16. The main magnetic block 13 and the auxiliary magnetic block 14 included in the heat dissipation mechanism attract each other in a manner of opposite magnetic properties. In the initial state, the main magnetic block 13 is far away from the auxiliary magnetic block 14 and does not produce a magnetic attraction effect. The end of the guide slide rod 15 at the outer end of the auxiliary magnetic block 14 is fixedly connected to the rear end of the traction cable 17. The traction cable 17 passes through the interior of the battery box body 1 and is fixedly connected to the dustproof partition 8.

[0029] like Figures 8-10 As shown, the battery box body 1 provides loading protection for the battery body 3, and the charging and discharging panel 2 on the front of the battery box body 1 controls the operation of the battery body 3. At the same time, it controls the heat dissipation fan module 6 installed at the rear of the battery box body 1 to work. The heat dissipation fan module 6 is in a negative pressure state to draw and discharge the hot airflow inside the battery box body 1 to the outside.

[0030] Furthermore, during the operation of the cooling fan module 6, the centrifugal slide cylinder 10 and centrifugal slide rod 11, which are distributed at equal angles at the front end, rotate. When the centrifugal force during the rotation exceeds the elastic potential energy of the return spring 12, the centrifugal slide rod 11 causes the main magnetic block 13 at the outer end to slide outward, so that the main magnetic block 13 and the auxiliary magnetic block 14 approach each other and reach the magnetic attraction range. This causes the auxiliary magnetic block 14 to slide towards the side closer to the main magnetic block 13, and the auxiliary magnetic block 14 drives the guide slide rod 15 to slide inward, thereby pulling the traction steel cable 17 fixedly connected at the outer end to be stretched. The traction steel cable 17 then drives the dustproof partition 8 fixedly connected at the front end to move backward, so that the dustproof partition 8 opens the originally blocked heat dissipation filter window 7. During the reciprocating opening and closing sliding, the dust removal brush plate 9 on the inner side of the dustproof partition 8 cleans the heat dissipation filter window 7, thereby preventing the accumulation of external dust from affecting the airflow of the heat dissipation filter window 7.

[0031] Example 2: To solve the problem of poor heat dissipation inside existing energy storage battery boxes, this example discloses the following technical solution: The battery box body 1 is provided with a flow guiding mechanism, which includes a main flow guiding frame 4 and a secondary flow guiding frame 5. The main flow guiding frame 4 and the secondary flow guiding frame 5 are used to guide the flowing air into the battery bodies 3 that are evenly distributed. The main flow guiding frame 4 is fixedly installed in an inverted "T" shape at the center of the battery box body 1. The main flow guiding frame 4 has an internal hollow structure, and its outer end is distributed on the heat dissipation filter windows 7 on the left and right sides in front of the battery box body 1. The rear end of the main flow guiding frame 4 extends to the heat dissipation fan module 6.

[0032] The flow guiding mechanism includes a flow guiding plate 18, which is rotatably mounted on the left and right sides of the main flow frame 4 via bearings. The flow guiding plates 18 are distributed in the gaps between adjacent battery bodies 3. A flow guiding gear 19 is fixedly mounted on the upper shaft of the flow guiding plate 18, and a flow guiding rack 20 is meshed with the inner side of the flow guiding gear 19. A guide screw 21 is rotatably mounted on the top surface of the main flow frame 4 via bearings. The guide screw 21 is threaded through the front end of the flow guiding rack 20. The rotation of the guide screw 21 drives the flow guiding rack 20 to move, thereby rotating the meshing flow guiding gear 19 and the flow guiding plate 18 to control the amount of heat dissipation airflow in the middle of the main flow frame 4.

[0033] like Figures 6-7As shown, when the cooling fan module 6 inside the battery box body 1 is working, it draws in the air inside the battery box body 1. The rear end of the main flow frame 4, which is distributed corresponding to the cooling fan module 6, has an internal hollow structure. Thus, the air is drawn in through the front end of the main flow frame 4, which is connected to the corresponding heat dissipation filter window 7. This allows the air to flow from front to back inside the main flow frame 4, thereby achieving heat exchange and dissipation through the battery bodies 3, which are distributed at equal distances.

[0034] Furthermore, the motor installed above the main flow frame 4 operates, rotating the guide screw 21 fixedly connected to the end of the output shaft. The guide rack 20, threadedly connected to the guide screw 21, is slidably installed on the main flow frame 4 for limiting, so that the guide screw 21 drives the guide rack 20 to move backward, and drives the meshing guide gear 19 and the guide rotating plate 18 to rotate, thereby controlling the size of the opening in the middle of the main flow frame 4, so that hot air can be transferred and transported through the airflow difference during the flow of air inside the main flow frame 4.

[0035] Example 3: In order to solve the problem of poor heat dissipation inside the existing energy storage battery box, this example discloses the following technical solution: the secondary flow guiding frame 5 included in the flow guiding mechanism is fixedly installed on the left and right sides inside the battery box body 1, and the inner side of the secondary flow guiding frame 5 is in close contact with the rear end of the battery body 3. The secondary flow guiding frame 5 is distributed in a hollow structure, and the front end of the secondary flow guiding frame 5 extends to the inner side of the heat dissipation filter window 7. At the same time, the rear end of the secondary flow guiding frame 5 extends to the front of the heat dissipation fan module 6. The interior of the secondary flow guiding frame 5 is provided with flow windows 22 at equal intervals.

[0036] The flow guiding mechanism includes flow openings 22 that are distributed at the gaps at the outer ends of adjacent battery bodies 3. The flow openings 22 and the flow guiding plate 18 correspond to each other and are used to guide the flow of air from the outside to the inside to realize the delivery and discharge of hot air. A flow guiding plate 23 is fixedly installed on the inner side of the flow openings 22. The flow guiding plate 23 is distributed in a manner with the front end facing inward and the rear end facing outward. The flow guiding plate 23 guides the airflow to the outside of the battery body 3.

[0037] like Figures 4-5 As shown, the heat dissipation fan module 6 inside the battery box body 1 operates, thereby drawing air from inside the secondary flow guide frame 5. The front end of the secondary flow guide frame 5 is distributed on one side of the heat dissipation filter 7, thereby drawing air through the heat dissipation filter 7 and conveying it from front to back inside the secondary flow guide frame 5. The flow guide plate 23 set inside the front end of the secondary flow guide frame 5 can guide part of the air entering through the heat dissipation filter 7, so that the external airflow can enter the interior of the secondary flow guide frame 5 and move along the secondary flow guide frame 5 at the outer end of the battery body 3.

[0038] Furthermore, as the air inside the secondary flow guide frame 5 flows from front to back, a flow guide plate 23 is provided on one side of the internal flow window 22 of the secondary flow guide frame 5. This guide plate 23 obstructs the flow of air and directs it outward, allowing some air to flow to the gap between adjacent battery bodies 3. This facilitates the flow of hot air between adjacent battery bodies 3. Simultaneously, as this airflow moves towards the center, it gradually approaches one side of the main flow guide frame 4. The rotating flow guide plate 18 opens the main flow guide frame 4, allowing the pressure difference inside the main flow guide frame 4 to absorb the air carrying the hot airflow. This air is then discharged to the outside of the battery box body 1 through the heat dissipation fan module 6, achieving efficient heat dissipation and improving the operation of the battery body 3.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
