Description

Technical Field

[0001] The present invention relates to the technical field of power equipment, and in particular to a ventilation and heat dissipation type energy storage battery cabinet. Background Art

[0002] An energy storage cabinet is a device that can store electrical energy and is typically composed of a battery pack, an inverter, a control chip, and other components. It can store electrical energy and release it for power supply when needed. It is typically used to provide backup power and stabilize grid voltage. The energy storage cabinet can smooth out fluctuations caused by the access of non-connected renewable energy sources to the grid, maintaining grid stability. It can also suppress load fluctuations, perform frequency and voltage regulation, and improve the power factor.

[0003] Most existing energy storage battery cabinets use air cooling to dissipate heat and cool the battery components within the cabinet, but this heat dissipation process still has certain drawbacks. For example, in Chinese Patent Publication No. CN119170983A, due to the compact arrangement of battery components within the cabinet, the traditional fan heat dissipation structure is simple and cannot fully dissipate heat for the tightly packed battery components in the middle of the cabinet. Another example is Chinese Patent Publication No. CN116154359B, which provides independent fans for each battery cell for heat dissipation. This undoubtedly increases energy consumption and occupies usable space in the equipment. Furthermore, the interlayer components of each battery cell are prone to accumulating large amounts of heat, making it difficult to dissipate heat. Furthermore, when the battery cabinet is used in a high-humidity environment, such as during the rainy season or cloudy weather, moisture in the air can easily enter the cabinet, increasing safety risks. Summary of the Invention

[0004] The present invention discloses a ventilation and heat dissipation type energy storage battery cabinet, which aims to solve the technical problems of poor heat dissipation effect and increased moisture safety hazards in existing heat dissipation methods.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A ventilation and heat dissipation type energy storage battery cabinet includes an energy storage cabinet, wherein a first heat dissipation mechanism for air cooling and heat dissipation is provided inside the energy storage cabinet, wherein the first heat dissipation mechanism includes a bellows fixed to the bottom of the energy storage cabinet, wherein a plurality of evenly distributed fans are installed at the bottom and top of the energy storage cabinet, wherein an air guide fin is installed through the top of the bellows, wherein a plurality of evenly distributed vertical rods in a rectangular shape are vertically fixed to the top of the bellows, wherein cross rods are connected through each other between the vertical rods, and wherein rack rods are connected through each other between the cross rods;

[0007] The energy storage cabinet is further provided with a second heat dissipation mechanism for water cooling. The second heat dissipation mechanism includes a water cooling unit installed at a side end of the energy storage cabinet. The water cooling unit is connected to a water cooling pipe filled with coolant. The water cooling pipe is coiled and layered and sequentially passes through the interiors of several of the vertical rods, the horizontal rods, and the frame rods.

[0008] The first heat dissipation mechanism is internally provided with an adjustment mechanism for controlling the direction of the gas path;

[0009] By changing the hydraulic pressure of the second heat dissipation mechanism and coordinating the operation of the regulating mechanism, the flow direction of the gas path of the first heat dissipation mechanism is changed.

[0010] By providing a first heat dissipation mechanism within a conventional energy storage battery cabinet, unlike conventional fan-based air cooling, this first heat dissipation mechanism conducts heat throughout the entire energy storage battery cabinet, directly bringing air between the tightly packed battery elements within the cabinet. This dissipates heat directly from within the cabinet, significantly improving the efficiency of conventional air cooling. Furthermore, on rainy days, the second heat dissipation mechanism operates synchronously, driving the regulating mechanism to change the operating mode of the first heat dissipation mechanism. This allows moist air to circulate through the cabinet without coming into contact with the internal battery elements. This protects the battery elements while maintaining heat dissipation efficiency, thereby improving the functionality and heat dissipation efficiency of conventional equipment.

[0011] In a preferred solution, the vertical rods are distributed at the inner corners of the energy storage cabinet and form supports. Both ends of the vertical rods are through-opening structures. Several horizontal rods and the air guide rows located on the same side are through-connected, and the surface of each horizontal rod is penetrated by several evenly distributed air guide holes.

[0012] By configuring the interior of a traditional energy storage battery cabinet to consist of horizontal bars, vertical bars, racks, and air guides, and using a bellows structure with an additional fan, the air guides are used to directly introduce air into the interior of the energy storage cabinet, allowing the air to be evenly distributed between each group of battery modules, thereby more effectively cooling the battery components inside the energy storage cabinet.

[0013] In a preferred solution, the second heat dissipation mechanism further includes a plurality of diverter coils connected to the side surfaces of each layer of the water-cooling tubes, and the diverter coils are fixedly installed at the bottom of each layer of the rack rods.

[0014] By additionally installing a water-cooling unit connected to a water-cooling pipe inside the energy storage cabinet, the water-cooling pipe is coiled and layered and sequentially passes through the interior of several vertical rods, horizontal rods and frame rods. At the same time, the side of each layer of water-cooling pipe is connected to a diversion coil. In rainy environments, the coolant is used to dissipate heat and cool the interior of the energy storage cabinet, thereby further improving the heat dissipation efficiency of the equipment.

[0015] In a preferred embodiment, the adjustment mechanism includes a fixed plate fixedly installed inside each of the cross bars, and the end of the fixed plate is slidably connected to a strip member through a plug-in slot, and the plug-in slot is opened at the end of the strip member, and the strip member is slidably distributed inside the cross bar. The surface of the strip member is provided with a number of evenly distributed adjustment holes, and the adjustment holes and the air guide holes are symmetrically distributed. A kit is distributed at the other end of the strip member, and an extrusion piece is slidably installed at the end of the kit, and the extrusion piece is in extrusion contact with the end of the strip member, and the kit is sleeved and installed on the outside of the water-cooling pipe and is connected to the inside of the water-cooling pipe through the water outlet.

[0016] By arranging a strip-shaped component structure pushed by an extrusion piece inside each crossbar, in a rainy environment, as the water-cooling unit operates and the hydraulic pressure inside the water-cooling tube increases, the extrusion piece at the end of the kit is pushed outward, squeezing the end of the strip-shaped component at the same time, causing the strip-shaped component to move horizontally, blocking the air guide holes on the crossbar, resulting in a sealed environment for the crossbar. At this time, moist air cannot be exposed to the interior of the energy storage cabinet, but can circulate from the interior of the energy storage cabinet, thereby protecting the battery components inside the energy storage cabinet and further improving the heat dissipation efficiency and functionality of the device.

[0017] In a preferred solution, a bottom heat dissipation cabinet is installed at the bottom of the energy storage cabinet, and a top heat dissipation cabinet is installed at the top of the energy storage cabinet. The upper and lower ends of the vertical rod respectively penetrate into the interior of the bottom heat dissipation cabinet and the top heat dissipation cabinet.

[0018] By installing a bottom heat dissipation cabinet at the bottom of the energy storage cabinet and a top heat dissipation cabinet on the top of the energy storage cabinet, the hot air or humid air inside the energy storage cabinet is discharged by using the two heat dissipation cabinets, thereby ensuring the integrity of the operation of this equipment.

[0019] From the above, it can be seen that the ventilation and heat dissipation type energy storage battery cabinet provided by the present invention has the following technical effects.

[0020] First, by configuring the interior of a traditional energy storage battery cabinet to consist of horizontal bars, vertical bars, racks, and air guides, and by using a bellows structure with an additional fan, the air guides are used to directly introduce air into the cabinet, allowing the air to be evenly distributed between each group of battery modules. This allows for more effective air cooling of each group of closely arranged battery components, thereby significantly improving the air cooling efficiency of traditional equipment.

[0021] Secondly, a water-cooling unit connected to a water-cooling pipe is additionally installed inside the energy storage cabinet. The water-cooling pipes are coiled and layered and sequentially pass through the interior of several vertical bars, horizontal bars, and rack bars. At the same time, a diversion coil is connected to the side of each layer of water-cooling pipes. In an environment with high humidity, the coolant is used to dissipate heat and cool the interior of the energy storage cabinet, resulting in the device having multiple heat dissipation modes, further improving the heat dissipation efficiency of the device.

[0022] Third, by providing a strip-shaped component structure pushed by an extrusion piece inside each crossbar, in rainy environments, as the water-cooling unit operates and the hydraulic pressure inside the water-cooling tube increases, the extrusion piece at the end of the kit is pushed outward, squeezing the end of the strip-shaped component, causing the strip-shaped component to move horizontally, blocking the air guide holes on the crossbar, and making the crossbar a sealed environment. At this time, the humid air introduced by the first heat dissipation mechanism cannot be exposed to the interior of the energy storage cabinet, but can circulate from the interior of the energy storage cabinet, protecting the battery components inside the energy storage cabinet and further improving the heat dissipation efficiency and functionality of the device. In addition, switching the heat dissipation mode is simple and fast. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] The present invention discloses a ventilation and heat dissipation type energy storage battery cabinet which is mainly used in scenarios of electric energy storage and power supply.

[0040] Reference Figures 1 to 14 A ventilation and heat dissipation type energy storage battery cabinet includes an energy storage cabinet 1. The energy storage cabinet 1 is provided with a first heat dissipation mechanism 2 for air cooling and heat dissipation. The first heat dissipation mechanism 2 includes a bellows 201 fixed to the bottom of the energy storage cabinet 1. A plurality of evenly distributed fans 202 are installed at the bottom and top of the energy storage cabinet 1. An air guide 203 is installed through the top of the bellows 201. A plurality of evenly distributed vertical rods 204 in a rectangular shape are vertically fixed to the top of the bellows 201. Cross rods 205 are connected between the vertical rods 204, and rack rods 206 are connected between the cross rods 205.

[0041] The energy storage cabinet 1 is also provided with a second heat dissipation mechanism 3 for water cooling. The second heat dissipation mechanism 3 includes a water cooling unit 301 installed at a side end of the energy storage cabinet 1. The water cooling unit 301 is connected to a water cooling pipe 302 filled with coolant. The water cooling pipe 302 is coiled and layered and sequentially passes through the interior of several vertical rods 204, horizontal rods 205, and frame rods 206.

[0042] The first heat dissipation mechanism 2 is internally provided with an adjustment mechanism 4 for controlling the direction of the gas path;

[0043] By changing the hydraulic pressure of the second heat dissipation mechanism 3 , the operation of the regulating mechanism 4 is controlled, thereby changing the direction of the gas path of the first heat dissipation mechanism 2 .

[0044] For example, when the hydraulic pressure (coolant circulation pressure) of the second heat dissipation mechanism 3 is less than a preset value, the regulating mechanism 4 is not triggered to operate, ensuring the normal operation of the first heat dissipation mechanism 2: the air introduced by the first heat dissipation mechanism 2 is normally exposed to the interior of the energy storage cabinet 1. When the hydraulic pressure of the second heat dissipation mechanism 3 is greater than or equal to the preset value, the regulating mechanism 4 is triggered to operate, changing the operating state of the first heat dissipation mechanism 2, so that the air introduced by the first heat dissipation mechanism 2 cannot be exposed to the interior of the energy storage cabinet 1 (and can be discharged from the energy storage cabinet 1 through other passages).

[0045] In this embodiment, when the device is used in an ordinary environment with normal air humidity, the first heat dissipation mechanism 2 operates to introduce air into the interior of the energy storage cabinet 1, thereby increasing air circulation and dissipating heat from the battery components within the energy storage cabinet 1. If heat dissipation efficiency needs to be improved, the second heat dissipation mechanism 3 can be operated simultaneously to achieve dual heat dissipation of water and air cooling, with high heat dissipation efficiency and significant heat dissipation effect. At this time, due to normal air humidity, the hydraulic pressure of the second heat dissipation mechanism 3 can be controlled to be less than a preset value, rendering the regulating mechanism 4 inoperative and allowing air to enter the energy storage cabinet 1 directly.

[0046] It is understandable that under normal conditions with normal air humidity, this device can be used to achieve the following three cooling modes: air cooling mode alone, water cooling mode alone, and air cooling and water cooling dual cooling mode (controlling the hydraulic pressure value to be less than the preset value).

[0047] When this device is used in an abnormally high humidity environment (such as the rainy season or in overcast and rainy weather), the first heat dissipation mechanism 2 and the second heat dissipation mechanism 3 operate simultaneously. Due to the high humidity, it is necessary to prevent the moist air introduced by the first heat dissipation mechanism 2 from being exposed to the interior of the energy storage cabinet 1. Therefore, the hydraulic pressure of the second heat dissipation mechanism 3 must be controlled to be equal to or greater than a preset value, triggering the operation of the regulating mechanism 4. This protects the battery components inside the energy storage cabinet 1 while maintaining heat dissipation efficiency.

[0048] It is understandable that in an abnormal environment with high air humidity, in order to avoid humid air being exposed to the interior of the energy storage cabinet 1, the present device can be used to implement the following two heat dissipation modes: a single water cooling mode and an air-cooling and water-cooling dual heat dissipation mode (controlling the hydraulic pressure value to be greater than or equal to the preset value).

[0049] Reference Figures 1 to 6 In a preferred embodiment, vertical rods 204 are distributed at the internal corners of the energy storage cabinet 1 and form supports. Both ends of the vertical rods 204 are through-opening structures. Several horizontal rods 205 and the air guide row 203 on the same side are connected through, and the surface of each horizontal rod 205 is penetrated by a plurality of evenly distributed air guide holes 207.

[0050] In actual use, the fan 202 is running to guide air into the interior of the wind box 201. The air inside the wind box 201 is then guided into the interior of each crossbar 205 through the air guide 203, the frame rod 206, and the vertical rod 204. When the adjustment mechanism 4 is not working, the air inside the crossbar 205 is blown directly into the interior of the energy storage cabinet 1 through the air guide holes 207, thereby increasing the air circulation to dissipate heat from the battery components inside the energy storage cabinet 1.

[0051] Reference Figures 1 to 2 、 Figure 8 In a preferred embodiment, the second heat dissipation mechanism 3 further includes a plurality of shunt coils 303 connected to the side of each layer of water cooling tubes 302, and the shunt coils 303 are fixedly installed at the bottom of each layer of the rack rod 206 ( Figure 8 Only the shunt coil 303 of the topmost water-cooling tube 302 is shown, and the shunt coil 303 on the lower water-cooling tube 302 is not shown); a shelf 208 is installed on the top of each layer of cross bars 205 and rack bars 206, and the battery module is installed on the top of the shelf 208. The shelf 208 will not block the air guide holes 207.

[0052] In practical applications, a flow distribution coil 303 is added to the water cooling tube 302, and the flow distribution coil 303 is attached to the lower surface of the frame plate 208 (such as Figure 2 As shown in FIG1 ), the coolant fills the water cooling tube 302 and the diverter coil 303, which increases the water cooling area, further improves the heat dissipation efficiency, and effectively removes the heat from the gaps between the battery components inside the energy storage cabinet 1; and the water cooling tube 302 is partially located inside the crossbar 205 (as shown in FIG1 ). Figure 12 As shown), the airflow flowing inside the cross bar 205 can cool the water cooling pipe 302, thereby reducing the temperature of the coolant.

[0053] Reference Figures 6 and 7 、 Figure 9 and Figure 14In a preferred embodiment, the adjustment mechanism 4 includes a fixed plate 401 fixedly installed inside each cross bar 205, and the end of the fixed plate 401 is slidably connected to the strip member 402 through the plug-in groove 4021. The plug-in groove 4021 is opened at the end of the strip member 402, and the strip member 402 is slidably distributed inside the cross bar 205. A plurality of evenly distributed adjustment holes 403 are opened on the surface of the strip member 402, and the adjustment holes 403 and the air guide holes 207 are symmetrically distributed. A kit 404 is distributed at the other end of the strip member 402, and an extrusion piece 405 is slidably installed at the end of the kit 404. The extrusion piece 405 is squeezed and contacted with the end of the strip member 402, and the kit 404 is installed on the outside of the water-cooling pipe 302 and is connected to the inside of the water-cooling pipe 302 through the water outlet 410.

[0054] The end surface of the extrusion member 405 is set as an inclined surface. When the inclined surface of the extrusion member 405 squeezes the strip member 402, the strip member 402 moves toward the fixed plate 401 ( Figure 6 The direction of the black arrow is the moving direction of the extrusion member 405).

[0055] Working principle: Under normal conditions with normal air humidity, in the air-cooled and water-cooled dual heat dissipation mode (the hydraulic pressure is controlled to be less than the preset value), while the water-cooling unit 301 is running, the coolant enters from the water inlet 410. However, since the coolant circulation pressure is controlled to be less than the preset value in this mode, the extrusion member 405 cannot be driven to move, and the adjustment mechanism 4 does not work.

[0056] Under abnormal conditions with high air humidity, in the dual cooling mode of air cooling and water cooling (controlling the hydraulic pressure value to be greater than or equal to the preset value), while the water cooling unit 301 is running, the coolant enters from the water inlet 410. In this mode, the coolant circulation pressure is controlled to be greater than or equal to the preset value, and the extrusion member 405 inside the kit 404 is squeezed by the coolant, and the adjustment mechanism 4 starts to work: the inclined surface of the extrusion member 405 squeezes the strip member 402, causing the strip member 402 to move toward the fixed plate 401 (such as Figure 10 and Figure 11 As shown in FIG. 4 ), the end of the fixed plate 401 moves relative to the inside of the plug-in slot 4021. As the strip-shaped member 402 moves, it also drives the adjustment hole 403 to move, resulting in a symmetrical dislocation between the adjustment hole 403 and the air guide hole 207. At this time, the moist air flowing through the interior of the horizontal bar 205 cannot be ejected from the air guide hole 207, but is guided out of the interior of the energy storage cabinet 1 along the vertical bar 204, thereby not affecting the normal operation of the battery components inside the equipment.

[0057] The bottom of the energy storage cabinet 1 is equipped with a bottom heat dissipation cabinet 101, and the top heat dissipation cabinet 102 is equipped with a top heat dissipation cabinet 102. The upper and lower ends of the vertical rod 204 extend through the interior of the bottom heat dissipation cabinet 101 and the top heat dissipation cabinet 102, respectively. Heat dissipation holes 103 are formed on the sides of the bottom heat dissipation cabinet 101 and the top heat dissipation cabinet 102, which are used to cooperate with the operation of the first heat dissipation mechanism 2 to remove normal air (under normal conditions) and humid air (under abnormal conditions) from the interior of the energy storage cabinet 1.

[0058] Furthermore, a first spring 406 is fixedly installed between the interlayer of each fixed plate 401 and the strip member 402, and a sliding interval 408 is opened on the inner wall of the end of the kit 404, and the extrusion member 405 is slidably installed inside the sliding interval 408. At the same time, a second spring 409 is fixedly connected between the extrusion member 405 and the kit 404. The second spring 409 is distributed inside the sliding interval 408. When the extrusion member 405 loses the pressure of the coolant, the second spring 409 will pull the extrusion member 405 to reset and move. At the same time, the strip member 402 that loses the extrusion member 405's extrusion contact will be pushed by the first spring 406, thereby resetting and moving. During this process, the positions of the fixed plate 401 and the cross bar 205 are fixed. The function of the fixed plate 401 is to fix the first spring 406 so that the strip member 402 can move back and forth along the inside of the cross bar 205.

[0059] It should be supplemented that: through slots 407 are provided through the side walls of the fixed plate 401 and the strip-shaped member 402 to ensure that the air flowing through the interior of the cross bar 205 is not blocked.

[0060] In actual application, when the coolant circulation pressure continues to increase, the extrusion piece 405 will be continuously squeezed by the coolant, and the extrusion piece 405 will overcome the elastic force of the second spring 409 and move outward, thereby causing the strip member 402 to move toward the fixed plate 401 and squeeze the first spring 406; when the coolant circulation pressure continues to decrease, the coolant gradually withdraws from the extrusion piece 405, the second spring 409 will retract, pulling the extrusion piece 405 inward to achieve reset, and at the same time the first spring 406 will stretch, pushing the strip member 402 to move away from the fixed plate 401 to achieve reset.

[0061] The aforementioned “preset value” is the external force value required when the first spring 406 deforms and drives the extrusion member 405 to squeeze the strip-shaped member 402 and cause displacement.

[0062] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
