Description

A temperature-controlled energy storage battery compartment Technical Field

[0001] This invention relates to the field of energy storage battery compartment technology, specifically a temperature-controlled energy storage battery compartment. Background Technology

[0002] The energy storage battery compartment, as a physical carrier for the centralized storage and management of a large number of energy storage units such as lithium-ion batteries, is a core component of an energy storage power station. For example, Chinese patent CN105591049A, entitled "A Sliding Adjustable Heat Dissipation and Insulation Battery Compartment," published on May 18, 2016, includes a hexahedral support frame. The bottom and top surfaces of the hexahedral support frame are sealed, and at least one of the four sides (front, back, left, and right) is equipped with a sliding insulated window, while the other sides are sealed. The insulated window is pushed and pulled according to the ambient temperature, thereby achieving heat dissipation and insulation adjustment of the battery compartment. The insulated window consists of an inner and outer insulation layer, a fire-resistant layer, and a metal outer shell, and is also surrounded by a sealing strip.

[0003] The existing technology has the following technical problems: When the existing battery compartment is in use, an exhaust fan is installed on the battery compartment to remove heat from the compartment. However, although the exhaust fan can remove heat, it cannot effectively cool the battery located in the middle of the compartment, which can easily lead to uneven heat dissipation of the battery.

[0004] Therefore, we propose a temperature-controlled energy storage battery compartment to address the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a temperature-controlled energy storage battery compartment to solve the problem mentioned in the background art. In the current battery compartments on the market, when in use, the exhaust fan is installed on the battery compartment to remove heat from the compartment. However, although the exhaust fan can remove heat, it cannot effectively cool the battery located in the middle of the compartment, which leads to uneven heat dissipation of the battery.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a temperature-controlled energy storage battery compartment, comprising a battery compartment body and a battery box cover installed on the upper end of the battery compartment body, wherein battery modules are placed inside the battery compartment body, and heat dissipation holes are provided on the lower front and rear sides of the battery compartment body, a limiting tube is fixed inside the battery compartment body, and a cold source delivery pipe is connected to the lower end of the limiting tube, the end of the cold source delivery pipe away from the limiting tube extends to the outside of the battery compartment body and is connected to a cold source supply device, a movable guide tube is installed on the limiting tube, and an exhaust hole is provided on the movable guide tube, the end of the movable guide tube away from the limiting tube is connected to a power component, and the power component is used to control the rotation of the movable guide tube.

[0007] Preferably, multiple heat dissipation holes are evenly distributed on the front and rear sides of the battery compartment, and each heat dissipation hole is equipped with a dustproof mesh.

[0008] By adopting the above technical solution, the dust in the airflow can be filtered through the dust filter installed inside the airflow cooling hole.

[0009] Preferably, the movable conduit is rotatable on the limiting tube, and a sealing ring is installed at the joint between the movable conduit and the limiting tube, and the interiors of the movable conduit and the limiting tube are interconnected.

[0010] By adopting the above technical solution, when airflow enters the inside of the limiting tube, the airflow can enter the inside of the movable duct and be discharged outward through the exhaust hole on the movable duct.

[0011] Preferably, the power component includes a rotating shaft fixed at the end of the movable guide tube away from the limiting tube, and a transmission gear is keyed to the rotating shaft, and a linkage toothed belt is meshed on the outer side of the transmission gear, and the rotating shaft at one end of the movable guide tube is connected to a servo motor.

[0012] By adopting the above technical solution, through the meshing action of the linkage toothed belt and the transmission gear, when one of the movable guide tubes rotates, the transmission gear and the linkage toothed belt can drive the other movable guide tubes to rotate synchronously.

[0013] Preferably, a central tube is inserted through the movable conduit, and turbulence detection components are installed at both the upper and lower ends of the central tube. A gap is reserved between the outer wall of the central tube inserted into the movable conduit and the inner wall of the central tube.

[0014] By adopting the above technical solution, the gap reserved between the central cannula and the movable catheter allows the airflow inside the movable catheter to flow normally without being blocked by the central cannula.

[0015] Preferably, the turbulence detection component includes a movable support frame, with the rod in the middle of the movable support frame inserted into the interior of the central insertion tube. One end of the movable support frame extending outside the central insertion tube is connected to a detection roller, and a distance sensor is fixed on the side of the movable support frame facing the movable guide tube. The rod in the middle of the movable support frame is connected to the interior of the central insertion tube via an auxiliary spring, and the end of the movable support frame extending into the interior of the central insertion tube forms an air storage chamber with the inner wall of the central insertion tube. The air storage chamber is connected to the connecting pipe and a retaining plate fixed to the end of the central insertion tube, and an air jet hole is opened on the side of the retaining plate facing the detection roller.

[0016] By adopting the above technical solution, the auxiliary spring can enable the movable support frame to return to its original position after moving on the central insertion tube.

[0017] Preferably, the detection roller is rotatably connected to one end of the movable support frame that extends out of the central insertion tube, and the end of the movable support frame that is inserted into the central insertion tube is circumferentially wrapped with a sealing ring, allowing the movable support frame to slide on the central insertion tube.

[0018] By adopting the above technical solution, the sealing performance of the movable support frame can be improved when it moves on the central insertion tube by using the sealing ring at the end of the movable support frame.

[0019] Preferably, the width of the detection roller is equal to the width of the battery module, and the distance sensor on the movable support frame is used to detect the distance between the roller and the movable guide tube.

[0020] By adopting the above technical solution, when the detection roller rotates with the moving support frame, the pressure between the detection roller and the battery module enables the moving support frame to move. The distance between the detection roller and the moving guide is detected by the distance sensor, and the curve of the moving support frame's telescopic movement distance when the battery module surface is smooth is obtained. When the battery bulges, the bulging area will further press the detection roller on the moving support frame, thereby causing the distance between the distance sensor and the moving guide to fluctuate, which is used to determine whether there is bulging damage on the surface of the battery module.

[0021] Preferably, the airflow inside the air storage chamber can communicate with the airflow inside the connecting pipe and the clamping plate, and the surface of the clamping plate is evenly distributed with multiple air jet holes.

[0022] By adopting the above technical solution, when the airflow inside the air storage chamber is compressed, the airflow inside can enter the interior of the clamping plate through the connecting pipe and be ejected outward through the jet holes on the clamping plate.

[0023] Compared with the prior art, the beneficial effects of the present invention are: the temperature-controlled energy storage battery compartment, by setting up horizontally placed pipes between adjacent batteries in the compartment, uses the cold air discharged from inside the pipes to uniformly cool the batteries in the compartment, and by using the rotation of the pipes, the cold air can be evenly distributed into the compartment.

[0024] 1. The cool air in the movable duct is dissipated into the battery compartment through the circumferentially opened exhaust holes, thereby cooling each battery module. At the same time, the rotation of the movable duct allows the airflow ejected from the exhaust holes to be evenly distributed into the battery compartment, avoiding uneven heat dissipation of the battery modules inside the battery compartment. This enables temperature control inside the energy storage battery compartment, allowing the battery modules to operate at a suitable temperature.

[0025] 2. As the detection roller rotates with the moving support frame, the pressure between the detection roller and the battery module causes the moving support frame to move. The distance between the detection roller and the moving guide is detected by the distance sensor, and the curve of the moving support frame's telescopic movement distance is obtained when the battery module surface is smooth. When the battery bulges, the bulging area will further press the detection roller on the moving support frame, causing the distance between the distance sensor and the moving guide to fluctuate, thereby determining whether there is bulging damage on the surface of the battery module.

[0026] 3. After the movable support frame located below the central insertion tube moves, it can squeeze the airflow in the corresponding air storage chamber into the interior of the card plate through the connecting pipe. The airflow inside the card plate is ejected towards the side wall of the battery compartment through the jet hole on it. The heat dissipation holes on the side wall of the battery compartment are located at a lower position. Therefore, the airflow ejected outward from the jet hole can also play a certain role in reverse blowing and cleaning the impurities stuck in the heat dissipation holes. Attached Figure Description

[0037] 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.

[0038] Example 1: Referring to Figures 1-9, existing battery compartments use exhaust fans to dissipate heat. However, while exhaust fans can dissipate heat, they are not effective at cooling the batteries located in the center of the compartment, leading to uneven heat dissipation. To address this problem, this example discloses a temperature-controlled energy storage battery compartment, including a battery compartment body 1 and a battery cover 2 mounted on the upper part of the battery compartment body 1. Battery modules 3 are placed inside the battery compartment body 1. Cooling holes 4 are provided on the lower front and rear sides of the battery compartment body 1. A limiting tube 5 is fixed inside the battery compartment body 1, and a cold source delivery pipe 6 is connected to the lower end of the limiting tube 5. The end of the cold source delivery pipe 6 away from the limiting tube 5 extends into the battery compartment body 1. The external part of the battery compartment 1 is connected to the cold source supply equipment. A movable guide tube 7 is installed on the limiting tube 5, and an exhaust hole 8 is opened on the movable guide tube 7. The end of the movable guide tube 7 away from the limiting tube 5 is connected to the power component. The power component is used to control the rotation of the movable guide tube 7. Multiple heat dissipation holes 4 are evenly distributed on the front and rear sides of the battery compartment 1, and a dustproof net is installed inside each heat dissipation hole 4. The movable guide tube 7 can rotate on the limiting tube 5, and a sealing ring is installed at the joint between the movable guide tube 7 and the limiting tube 5. The interiors of the movable guide tube 7 and the limiting tube 5 are interconnected. The power component includes a rotating shaft fixed on the end of the movable guide tube 7 away from the limiting tube 5, and a transmission gear 9 is keyed on the rotating shaft. A linkage toothed belt 10 is meshed on the outer side of the transmission gear 9. The rotating shaft at one end of the movable guide tube 7 is connected to a servo motor.

[0039] When the battery compartment is in use, the cold source delivery pipe 6 is connected to an external cold source supply device. The cold source here is airflow. When the cold source supply device delivers cold source into the cold source delivery pipe 6, the cold source can enter the interior of the movable duct 7 through the limiting pipe 5. The cold air in the movable duct 7 is dissipated outward into the battery compartment 1 through the circumferentially opened exhaust holes 8, thereby cooling each battery module 3. Simultaneously, the airflow after heat exchange can also be discharged outward through the heat dissipation holes 4 on the side of the battery compartment 1. Then, the servo motor is turned on... When the machine is turned on, one of the movable guide tubes 7 can rotate. After the movable guide tube 7 rotates, it can drive the other movable guide tubes 7 to rotate synchronously through the meshing of the transmission gear 9 and the linkage toothed belt 10. The rotation of the movable guide tube 7 can make the airflow ejected from the exhaust port 8 evenly distributed into the interior of the battery compartment 1, avoiding uneven heat dissipation of the battery modules 3 inside the battery compartment 1. At the same time, the movable guide tube 7 is located between adjacent battery modules 3. At this time, when exhausting, the battery modules 3 in each position can come into contact with the cold source for cooling.

[0040] Example 2: The technical content disclosed in this example is a further improvement based on Example 1. As shown in Figures 6-9, a central tube 11 is inserted through the movable conduit 7, and turbulence detection components 12 are installed at both ends of the central tube 11. A gap is reserved between the outer wall of the central tube 11 inserted into the movable conduit 7 and the inner wall of the central tube 11. The turbulence detection component 12 includes a movable support frame 121, and the rod in the middle of the movable support frame 121 is inserted into the interior of the central tube 11. One end of the movable support frame 121 extending outside the central tube 11 is connected to a detection roller 122, and a distance sensor 123 is fixed on the side of the movable support frame 121 facing the movable conduit 7. The rod in the middle of the movable support frame 121 is connected to the interior of the central tube 11 via an auxiliary spring 124, and the movable support frame 121 extends... One end of the tube 11 is inserted into the center tube 11 and forms an air storage chamber 125 with the inner wall of the center tube 11. The air storage chamber 125 is connected to the connecting pipe 126 and the retaining plate 127 fixed on the end of the center tube 11. The retaining plate 127 has an air jet hole 128 on the side facing the detection roller 122. The detection roller 122 is rotatably connected to the end of the movable support frame 121 that extends out of the center tube 11. The end of the movable support frame 121 inserted into the center tube 11 is circumferentially wrapped with a sealing ring. The movable support frame 121 can slide on the center tube 11. The width of the detection roller 122 is equal to the width of the battery module 3. The distance sensor 123 on the movable support frame 121 is used to detect the distance between it and the movable guide tube 7. The airflow inside the air storage chamber 125 can communicate with the airflow inside the connecting pipe 126 and the retaining plate 127. The surface of the retaining plate 127 has multiple air jet holes 128 evenly distributed.

[0041] Because a central insertion tube 11 is inserted through the movable conduit 7, the movable conduit 7 can drive the central insertion tube 11 to rotate synchronously when it rotates. The rotation of the central insertion tube 11 causes the movable support frame 121 and the detection roller 122 to rotate synchronously. When the movable support frame 121 rotates, the detection roller 122 at its end contacts the surface of the battery module 3. The pressure on the detection roller 122 causes the movable support frame 121 to move towards the center of the central insertion tube 11. This movement of the movable support frame 121 increases the volume of the air storage chamber 125. As the internal volume of the air storage chamber 125 increases... The air jet 128 on the card plate 127 can be used to draw in the air around the battery module 3. When the central tube 11 rotates, the detection roller 122 on its movable support frame 121 is separated from the battery module 3. The movable support frame 121 and the detection roller 122 are reset and rebounded under the action of the auxiliary spring 124. After the movable support frame 121 is reset, it can spray the airflow inside the air storage chamber 125 out through the air jet 128 on the card plate 127. This cycle repeats. By using the air jet 128 to draw in and expel air, the airflow around the battery module 3 can be accelerated, making its heat dissipation effect better.

[0042] In addition, the turbulence detection component 12, which is close to the inner wall of the battery compartment 1, rotates with the central insertion tube 11 as shown in Figures 8 and 9, and the orientation shown in Figure 9 is used as an example.

[0043] Because both ends of the central insertion tube 11 are equipped with turbulence detection components 12, when the detection roller 122 at the upper end of the central insertion tube 11 is squeezed against the side of the battery module 3, the upper detection roller 122 and the movable support frame 121 move towards the center of the central insertion tube 11. Since the interior of the central insertion tube 11 is hollow, when the upper movable support frame 121 moves towards the center of the central insertion tube 11, the airflow can push the movable support frame 121 located below the central insertion tube 11 to move synchronously. At this time, the lower movable support frame... 121 moves away from the center of the central insertion tube 11. After the lower movable support frame 121 moves, it can squeeze the airflow in the corresponding air storage chamber 125 into the inside of the card plate 127 through the connecting pipe 126. The airflow inside the card plate 127 is ejected towards the side wall of the battery compartment 1 through the jet hole 128 on it. The heat dissipation hole 4 on the side wall of the battery compartment 1 is located at a lower position. Therefore, the airflow ejected outward from the jet hole 128 can also play a certain role in reverse blowing and cleaning the impurities stuck in the heat dissipation hole 4.

[0044] Meanwhile, a distance sensor 123 is also installed on the movable support frame 121. The distance sensor 123 can detect the distance between itself and the movable guide tube 7. When the surface of the battery module 3 is normal and without bulges, the detection roller 122 contacts and squeezes the battery module 3, causing the movable support frame 121 to move towards the movable guide tube 7. This results in a curve showing the distance traveled by the movable support frame 121 after being squeezed when the surface of the battery module 3 is smooth. This distance curve represents the distance between the distance sensor 123 and the movable guide tube 7. When there are bulges on the surface of the battery module 3 after use, the bulges protrude outwards and push the contacting detection roller 122 deeper, causing the detection roller 122 and the movable support frame 121 to move a greater distance. At this time, when the distance sensor 123 measures the distance between itself and the movable guide tube 7, the curve will fluctuate. Based on this data fluctuation, it is also possible to determine whether there are bulges on the surface of the battery module 3.

[0045] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0046] 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.
