Description

Technical Field

[0001] This invention relates to the field of new energy storage equipment technology, specifically to a new energy cabinet with an adaptive heat dissipation system. Background Technology

[0002] With the advancement of dual-carbon goals and the rapid development of the new energy industry, electrochemical energy storage systems, as core equipment for power system peak shaving and frequency regulation and renewable energy consumption, have been widely used. The new energy cabinet is the basic unit of the electrochemical energy storage system, which integrates a large number of core components such as battery modules, battery management system (BMS), and power distribution module. During the charging and discharging process, battery modules generate a large amount of Joule heat and chemical reaction heat. If the heat cannot be dissipated in a timely and effective manner, it will lead to an increase in the internal temperature of the battery module and uneven temperature distribution. This will not only accelerate battery aging and shorten its service life, but in severe cases, it will also cause thermal runaway, resulting in safety accidents such as fires and explosions.

[0003] Existing forced air cooling systems mostly use side-blowing or top-blowing methods, which make it difficult for airflow to reach the bottom of the battery module and the gap between the modules. This results in excessively high local temperatures and poor temperature uniformity. The airflow between the bottom of the battery module and the mounting plate is also obstructed, creating obvious heat dissipation dead zones. Long-term operation will lead to accelerated performance degradation of the bottom battery. Therefore, a new energy cabinet with an adaptive heat dissipation system is proposed. Summary of the Invention

[0004] This invention provides a new energy cabinet with an adaptive heat dissipation system. This new energy cabinet with an adaptive heat dissipation system can solve the problems mentioned in the background art, which are that existing forced air cooling systems mostly adopt side blowing or top blowing methods, making it difficult for airflow to reach the bottom of the battery module and the gap between the modules, resulting in excessively high local temperature, poor temperature uniformity, poor airflow between the bottom of the battery module and the mounting plate, forming obvious heat dissipation dead corners, and long-term operation will lead to accelerated performance degradation of the bottom battery.

[0005] To achieve the above objectives, this solution provides a new energy cabinet with an adaptive heat dissipation system, including an energy cabinet, which includes an upper layer and a lower layer. The upper layer of the energy cabinet is provided with a perforated plate for placing battery equipment. A baffle is sealed on the side of the perforated plate. The baffle is made of transparent acrylic plate. The upper layer of the energy cabinet, the perforated plate and the baffle form a negative pressure cavity. The energy cabinet is equipped with a matrix heat dissipation mechanism, which includes several cooling fans. The air inlet of each cooling fan is connected to the negative pressure chamber. As the heat generated by the battery device increases, the number of cooling fans turned on increases accordingly.

[0006] Optionally, a movable frame is provided at the bottom of the perforated plate, the movable frame is located adjacent to the cooling fan, and a filter cloth for filtering dust is installed on the movable frame.

[0007] Optionally, the movable frame adopts a modular design, with guide rails installed on the upper layer of the energy cabinet and the bottom of the perforated plate, a slider installed on the movable frame, the slider being slidably mounted on the guide rails, and handles installed at both ends of the movable frame.

[0008] Optionally, a Velcro fastener is provided between the filter cloth and the movable frame, wherein the hook side of the Velcro fastener is connected to the filter cloth and the loop side of the Velcro fastener is connected to the movable frame.

[0009] Optionally, when multiple energy cabinets are connected in series, a connecting sleeve is provided between the energy cabinets. The connecting sleeve is a flexible cloth sleeve, and both ends of the connecting sleeve are respectively connected to the negative pressure cavity on the energy cabinet.

[0010] Optionally, a sealing seat is installed in the series section of the negative pressure chamber, a rubber gasket is provided on the sealing seat, and rigid gaskets are installed at both ends of the connecting sleeve. The rigid gaskets are stainless steel gaskets, and bolts are provided on the sealing seat. After the connecting sleeve is installed, the rigid gaskets are sealed on the rubber gaskets by the bolts.

[0011] Optionally, a rotating plate is hinged inside the movable frame. The rotating plate is located on the side of the filter cloth near the cooling fan. A torsion spring is provided on the hinge shaft of the rotating plate. One end of the torsion spring is connected to the hinge shaft, and the other end of the torsion spring is connected to the rotating plate.

[0012] Optionally, a pull ring is provided on the side of the filter cloth near the rotating plate, and an elastic rope is installed at the bottom of the rotating plate, with the other end of the elastic rope connected to the pull ring.

[0013] Optionally, a fixed base is installed at the bottom of the movable frame. The fixed base is configured as an arc-shaped plate, and a plurality of protrusions are provided on the inner side of the fixed base. The protrusions are configured as convex strips with arc-shaped surfaces. A spring plate is installed on the side of the rotating plate near the fixed base. An abutment block is provided at the top of the spring plate. The abutment block intermittently abuts against the protrusion. A limiting block is provided at the bottom of the fixed base for limiting the abutment block.

[0014] Optionally, a dust collection box is installed on the side of the movable frame. The dust collection box is installed on the side of the filter cloth away from the cooling fan. After the filter cloth is shaken, the dust on the filter cloth falls into the dust collection box.

[0015] Through the above technical solution, the new energy cabinet with an adaptive heat dissipation system provided by this solution will be used as follows: 1. A negative pressure chamber is set at the bottom of the mesh plate to force the airflow around the battery device to flow downward, prevent the presence of heat dissipation dead corners at the bottom of the battery device, and enable the airflow to fully cover all surfaces of the battery module, effectively extending the battery's service life. 2. When the heat dissipation power consumption increases, the number of cooling fans starts increases, and a strong airflow is formed inside the negative pressure chamber, which drives the rotating plate to swing. This causes the contact block and the protrusion on the spring plate to come into contact, thereby causing the rotating plate to vibrate while swinging. This, in turn, shakes the filter cloth through the elastic rope to prevent the filter cloth from being blocked by dust and ensures that the heat dissipation airflow passes through normally.

[0016] Other features and advantages of this solution will be described in detail in the following detailed implementation section. Attached Figure Description

The terms "first" and "second" are used to distinguish one element from another and do not have sequential or importance. Furthermore, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings indicate the same or similar elements, which will not be repeated here.

[0029] In this solution, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this solution based on the specific circumstances.

[0030] Based on some embodiments of this solution, a new energy cabinet with an adaptive heat dissipation system is provided, for reference. Figures 1 to 9 As shown, the new energy cabinet with an adaptive heat dissipation system includes an energy cabinet 101, which is welded from cold-rolled steel plate and coated with an epoxy resin anti-corrosion layer. The interior of the energy cabinet 101 is divided into an upper and lower layer by a horizontal partition. A matrix heat dissipation mechanism is installed on the rear wall of the energy cabinet 101. In this embodiment, the matrix heat dissipation mechanism includes six cooling fans 102, evenly arranged in a 1×6 matrix. The cooling fans 102 are DC axial fans with a rated voltage of 24V, a rated power of 15W, and a maximum airflow of 120m³ / h. 3 / h, the air inlet of each cooling fan 102 is connected to the negative pressure chamber through a flange, and the air outlet leads to the outside of the energy cabinet 101. In specific implementation, rainproof louvers can be installed at the air outlet to prevent rainwater from entering the cabinet.

[0031] A perforated plate 103 is horizontally installed in the middle of the upper layer of the energy cabinet 101. The perforated plate 103 is made of 304 stainless steel and has evenly distributed circular through holes with a diameter of 8mm on its surface. The spacing between the through holes is 15mm, which ensures sufficient support strength for battery modules with a single weight of no more than 50kg, while also ensuring smooth airflow. Baffles 104 are sealed and installed on the four sides of the perforated plate 103. The baffles 104 are made of 5mm thick acrylic transparent plates and are sealed and connected to the inner wall of the energy cabinet 101 and the edge of the perforated plate 103 by silicone sealing strips and stainless steel screws.

[0032] The inner wall of the upper layer of the energy cabinet 101, the lower surface of the perforated plate 103, and the baffle 104 together form a closed negative pressure chamber. Specifically, the matrix fan has three modes: standby natural cooling mode, low-load cooling mode, and high-load full-speed cooling mode. The standby natural heat dissipation mode is as follows: when the battery device is in standby mode, the charging and discharging current is less than 0.1C, and the average temperature of the battery module is ≤25℃, the PLC controller controls all cooling fans 102 to turn off. At this time, the energy cabinet 101 relies on the natural ventilation opening on the top layer for natural heat dissipation. The low-load heat dissipation mode is as follows: When the battery device is in a low-load operating state, the charging and discharging current is 0.1C-0.5C, and the average temperature of the battery module is in the range of 25℃-35℃, the PLC controller controls the three cooling fans 102 in the matrix heat dissipation mechanism to turn on. The turned-on cooling fans 102 draw air to form a negative pressure in the negative pressure chamber. Outside air enters from the air inlet at the top of the upper layer of the energy cabinet 101, flows through the upper surface and sides of the battery module, and carries away the heat generated by the battery. Due to the negative pressure of the negative pressure chamber, the airflow will be forced to flow downward, pass through the through holes of the mesh plate 103, and flow through the bottom of the battery module and the gap between the modules, eliminating the heat dissipation dead corners that exist in the traditional side-blowing or top-blowing methods. The airflow carrying heat enters the negative pressure chamber after passing through the mesh plate 103, and is finally discharged to the outside by the turned-on cooling fans 102. The high-load full-speed heat dissipation mode is as follows: When the battery device is in full-load operation, the charging and discharging current is greater than 0.5C, and the average temperature of the battery module exceeds 35℃, the PLC controller controls all 6 cooling fans 102 to be turned on. The strong airflow can quickly remove the large amount of heat generated by the battery and prevent the battery temperature from rising sharply.

[0033] Thus, the new energy cabinet with adaptive heat dissipation system provided by this solution achieves adaptive matching between heat dissipation power and battery heat generation power during use. Compared with traditional fixed power heat dissipation systems, it can reduce heat dissipation energy consumption by more than 30% under the average annual operating conditions. At the same time, the negative pressure airflow organization method enables the airflow to fully cover all surfaces of the battery module, effectively extending the battery's service life.

[0034] It should be noted that all cooling fans 102 are electrically connected to the PLC controller. The PLC controller adopts the Siemens S7-200SMART series. NTC temperature sensors are installed on the top, bottom and side of each battery module. The temperature sensors have a measurement range of -40℃ to 125℃, an accuracy of ±0.5℃, and a sampling period of 1 second. The PLC controller collects battery temperature data in real time through the temperature sensors and automatically controls the number and speed of the cooling fans 102 according to the temperature changes, so as to realize the adaptive adjustment of heat dissipation power.

[0035] For some implementations of this solution, please refer to Figure 4 At the bottom of the perforated plate 103, near the cooling fan 102, there is a movable frame 201. The movable frame 201 is made of aluminum alloy profile splicing. The movable frame 201 adopts a modular design. Handles 202 are installed at the front and rear ends of the movable frame 201 respectively. The surface of the handles 202 is provided with anti-slip texture to facilitate maintenance personnel to pull the movable frame 201.

[0036] A filter cloth 204 for filtering dust is installed on the movable frame 201. The filter cloth 204 is made of HEPA filter material, which can effectively block dust and particulate matter in the air. A dust collection box 203 is detachably installed on the side of the movable frame 201, on the side of the filter cloth 204 away from the cooling fan 102. The dust collection box 203 is made of PP plastic and has an opening at the top to collect dust that falls off when the filter cloth 204 is shaken. The dust collection box 203 is connected to the movable frame 201 by a buckle, which is convenient for disassembly and cleaning.

[0037] Guide rails 205 are installed on the left and right inner walls of the upper layer of the energy cabinet 101 and at the corresponding positions on the bottom of the mesh plate 103. Four sliders 206 are installed on the upper and lower sides of the moving frame 201. The sliders 206 are embedded with balls to reduce sliding resistance. The sliders 206 are slidably installed on the guide rails 205 so that the moving frame 201 can be pulled out horizontally along the guide rails 205 for easy maintenance.

[0038] Specifically, inside the movable frame 201, a rotating plate 207 is hinged to the side of the filter cloth 204 near the cooling fan 102. The rotating plate 207 is made of ABS engineering plastic with a thickness of 3mm. The hinge shaft of the rotating plate 207 is horizontally set, and both ends are rotatably connected to the inner wall of the movable frame 201 through deep groove ball bearings. A torsion spring is sleeved on the hinge shaft. One end of the torsion spring is fixedly connected to the hinge shaft, and the other end is fixedly connected to the side of the rotating plate 207.

[0039] On the side of the filter cloth 204 near the rotating plate 207, a nylon pull ring 214 is sewn in the center. The bottom end of the rotating plate 207 is fixedly connected to an elastic rope 208 by a plastic buckle. The other end of the elastic rope 208 is tied to the pull ring 214. The elastic rope 208 is made of natural rubber.

[0040] The bottom of the movable frame 201 is fixedly mounted with a fixed base 210 by screws. The fixed base 210 is an arc-shaped plate, and its curvature matches the movement trajectory of the bottom end when the rotating plate 207 swings.

[0041] A spring plate 209 is fixedly mounted on the side of the rotating plate 207 near the fixed base 210 by screws. A cylindrical abutment block 211 is welded to the top of the spring plate 209. Multiple protrusions 212 are evenly arranged on the inner surface of the fixed base 210. The protrusions 212 are arc-shaped raised strips. The abutment block 211 and the protrusions 212 make intermittent contact. A limit block 213 is provided at the bottom of the fixed base 210 to limit the maximum swing angle of the rotating plate 207 and prevent the rotating plate 207 from swinging excessively and damaging the elastic rope 208.

[0042] The filter cloth 204 is connected to the movable frame 201 by Velcro 215. The barbed side of the Velcro 215 is sewn to the four edges of the filter cloth 204, and the rough side of the Velcro 215 is attached to the corresponding position of the movable frame 201 with adhesive, making it convenient to disassemble and replace the filter cloth 204.

[0043] The vibration operation process of the filter cloth self-cleaning mechanism in this embodiment is as follows: When the number of cooling fans 102 turned on is small (≤3) and the airflow speed in the negative pressure chamber is slow (≤0.3m / s), the impact force of the airflow on the rotating plate 207 is less than the elastic force of the torsion spring. The rotating plate 207 remains stationary under the action of the torsion spring, and the self-cleaning mechanism does not work. At this time, the filter cloth 204 only plays the role of filtering dust, and the dust gradually adheres to the windward side of the filter cloth 204. When the cooling fan 102 is fully turned on, the airflow impact on the rotating plate 207 increases, causing the rotating plate 207 to swing at a maximum angle of ±30°. At this time, the contact block 211 and the protrusion 212 continuously contact each other, and the rotating plate 207 vibrates. The vibration of the rotating plate 207 is transmitted to the filter cloth 204 through the elastic rope 208, causing the filter cloth 204 to shake. This can shake off the stubborn dust embedded in the fiber gaps of the filter cloth 204, effectively preventing the filter cloth 204 from clogging.

[0044] Furthermore, when the dust in the dust collection box 203 accumulates to a certain level, the maintenance personnel only need to open the energy cabinet 101, pull out the moving frame 201, remove the dust collection box 203, and empty the dust. When the filter cloth 204 has been used for a period of time and the filtration efficiency decreases, the old filter cloth can be directly peeled off through the Velcro 215 and replaced with a new filter cloth without disassembling any other parts.

[0045] For some implementations of this solution, please refer to Figure 2 When multiple energy cabinets 101 are connected in series to form a large-capacity energy storage system, adjacent energy cabinets 101 are connected by a connecting sleeve 301. The connecting sleeve 301 is a flexible cloth sleeve made of fireproof and flame-retardant PVC coated canvas with a thickness of 1mm. The cross-section of the connecting sleeve 301 is square, and its size is consistent with the opening size of the negative pressure cavity on the side wall of the energy cabinet 101. The length can be customized according to the distance between adjacent energy cabinets 101. In specific implementation, a steel wire skeleton can be set inside the connecting sleeve 301 to prevent it from collapsing under negative pressure and affecting airflow.

[0046] Furthermore, on the side wall of each energy cabinet 101, a square opening is provided corresponding to the position of the negative pressure chamber. A sealing seat 304 is welded to the edge of the opening, and a rubber pad 303 is attached to the end face of the sealing seat 304. The rubber pad 303 is made of nitrile rubber.

[0047] Rigid gaskets 302 are sewn onto both ends of the connecting sleeve 301. The rigid gaskets 302 are made of 304 stainless steel and their shape matches that of the sealing seat 304. The rigid gaskets 302 have bolt holes corresponding to the sealing seat 304. During installation, one end of the connecting sleeve 301 is first put onto the sealing seat 304 of an energy cabinet 101, so that the rigid gaskets 302 fit against the rubber gaskets 303. Then, the rigid gaskets 302 and the sealing seat 304 are fastened together by bolts 305.

[0048] It should be noted that the easily damaged parts used in this solution, such as torsion springs, rubber pads 303, elastic ropes 208 and filter cloths 204, should be replaced and maintained by staff when the function is not ideal.

[0049] Through the above technical solution, the new energy cabinet with adaptive heat dissipation system provided by this solution forms a closed negative pressure cavity under the mesh plate 103 where the battery module is placed. The cooling fan 102 of the matrix heat dissipation mechanism draws air to form a negative pressure in the negative pressure cavity, forcing the external airflow to flow in from the top and side of the battery module and then pass down through the mesh plate 103, flowing through the bottom of the battery module and the gap between the modules, thus eliminating the heat dissipation dead corners of the traditional air-cooled structure. The control unit adjusts the number of cooling fans 102 that are turned on according to the battery heat generation status obtained by the temperature acquisition module, so as to achieve adaptive matching between heat dissipation power and battery heat generation power. When all cooling fans 102 are turned on under high load and a strong airflow is formed in the negative pressure chamber, the airflow impacts the rotating plate 207 to overcome the torsion spring force and swing. The contact block 211 on the rotating plate 207 and the protrusion 212 of the fixed base 210 intermittently collide to generate vibration. The vibration is transmitted to the filter cloth 204 through the elastic rope 208 to achieve automatic dust removal. When multiple cabinets are used in parallel, adjacent energy cabinets 101 can be connected in series through flexible connecting sleeves 301 to share heat dissipation resources. This invention realizes unified heat dissipation of multiple energy cabinets 101, saving heat dissipation costs. At the same time, the design of the flexible connecting sleeves 301 can adapt to the installation requirements of different cabinet spacings, and the installation and disassembly are very convenient, which facilitates the expansion and transformation of the energy storage system.

[0050] The preferred embodiments of this solution have been described in detail above with reference to the accompanying drawings. However, this solution is not limited to the specific details in the above embodiments. Within the scope of the technical concept of this solution, various simple modifications can be made to the technical solution, and these simple modifications all fall within the protection scope of this solution.

[0051] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this solution will not describe the various possible combinations separately.

[0052] Furthermore, various implementations of this solution can be combined in any way, as long as they do not violate the spirit of this solution, they should also be regarded as the content disclosed in this solution.
