Description

[0001] The present invention belongs to the technical field of energy storage devices, and particularly relates to an energy storage container with a liquid cooling system. Background Art

[0002] An energy storage container is an integrated energy storage system developed for the needs of the mobile energy storage market. It integrates a battery cabinet, a lithium battery management system, and a container dynamic environment monitoring system inside. The container energy storage system has the characteristics of simplifying infrastructure construction costs, short construction periods, high modularity, convenience in transportation and installation, etc., and can be applied to power stations such as thermal power, wind energy, and solar energy, or application scenarios such as islands, communities, schools, research institutions, factories, and large load centers.

[0003] Existing energy storage containers usually use air conditioners to dissipate heat from the inside of the container, so that the space inside the container is always within a relatively low temperature range, thereby preventing internal electrical components from being damaged due to high temperature. However, the size of the container is generally large, and its internal space is also large. Cooling the internal space by an air conditioner will consume a large amount of energy. Therefore, we propose an energy storage container with a liquid cooling system. Summary of the Invention

An insertion pipe and a conduit are integrally formed at one end of the connecting male nozzle away from the fixing frame, and an insertion tube is integrally formed on a side outer wall of the insertion pipe.

[0009] Further, a top frame is threadedly connected to one end of the connecting female nozzle, and a spring is mounted on an outer wall on one side of the top frame through a screw. A piston is inserted into one end of the spring. A throat is integrally formed inside the connecting female nozzle, and the piston is in contact with the throat. A slot is formed in an outer wall on one side of the connecting female nozzle, and a clamping groove is formed in an inner wall on a side of the slot. The insertion pipe is inserted into the interior of the slot, and a snap ring is clamped in the interior of the clamping groove. The conduit is inserted into the interior of the throat, and the ejector rod is in contact with the piston.

[0010] Further, the liquid cooling system includes a housing. A heat dissipation fin is mounted inside the housing through a screw, and a condensing pipe is clamped inside the heat dissipation fin.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1: Please refer to Figures 1 to 11, the present invention provides a technical solution: an energy storage container with a liquid cooling system, including a box body 1, a fire protection system 2 is fixedly installed on the outer wall of the top of the box body 1 by bolts, and a liquid cooling system 3 is fixedly installed on the outer wall of one side of the box body 1 by bolts. A control room 11 and an energy storage room 12 are preset inside the box body 1. A heat insulation layer 121 is bonded to the inner wall of the energy storage room 12. The heat insulation layer 121 isolates the internal and external temperatures, preventing the energy consumption of the device from increasing when the external weather is too hot. And a lining layer 122 is riveted to the inner wall of the heat insulation layer 121. A number of flame retardant walls 123 are welded inside the energy storage room 12. A flame retardant door 124 is rotatably connected to the inside of the flame retardant wall 123 through a hinge. The flame retardant wall 123 and the flame retardant door 124 can divide the energy storage room 12 into several small chambers. When a device in one chamber fails, it will not have too much impact on other chambers. And a vacuum glass door 127 is rotatably connected to the adjacent two flame retardant walls 123 through a hinge. The vacuum glass door 127 is used to block the transfer of temperature. A battery rack 126 is installed between the flame retardant wall 123, the vacuum glass door 127 and the lining layer 122 by bolts. And a number of carrier racks 1261 are fixedly installed on the side inner wall of the battery rack 126 by bolts. A battery pack 1262 is inserted between two adjacent carrier racks 1261. And a cold plate 1263 is inserted between two opposite carrier racks 1261. The cold plate 1263 is in contact with the adjacent battery pack 1262. A number of cold branch pipes 1264 and a number of hot branch pipes 1265 are fixedly installed on the outer wall of the back of the battery rack 126 by pipe clamps. And both the cold branch pipe 1264 and the hot branch pipe 1265 are in communication with the cold plate 1263. The battery pack 1262 and the hot branch pipe 1265 are respectively in communication with the liquid cooling system 3.

[0033] As can be seen from the above description, the present invention has the following beneficial effects: In the present invention, by setting the energy storage room 12, the flame retardant wall 123 and the liquid cooling system 3, the liquid cooling system 3 can accurately dissipate heat from the battery pack 1262 inside the battery rack 126 through the cold plate 1263, rather than dissipating heat from the entire inside of the energy storage room 12 through an air conditioner, thereby greatly reducing the energy consumption required for heat dissipation.

[0034] Further, refer to Figure 4 , a number of equally spaced chutes 12611 are opened on the outer wall of one side of the carrier rack 1261, and a temperature sensor 12612 is fixedly installed on the outer wall of one side of the carrier rack 1261 by bolts. Insertion strips 12632 are integrally formed on both outer walls of the cold plate 1263, and the insertion strips 12632 are inserted into the inside of the chutes 12611.

[0035] Embodiment two: Please refer to Figures 1 to 11As shown, based on the first embodiment, the present invention provides a technical solution: refrigerant grooves 12631 are arranged at equal distances inside the cold plate 1263. Two male connectors 1267 are threadedly connected to one outer wall of the cold plate 1263, and the male connectors 1267 communicate with the refrigerant grooves 12631. A cover plate 12633 is fixedly installed on the top outer wall of the cold plate 1263 through bolts, and a rib 12634 is integrally formed on the top outer wall of the cover plate 12633. After the cold plates 1263 are installed, the ribs 12634 of the upper and lower cold plates 1263 are in contact with and press against each other, so that the cold plate 1263 can fit more closely with the battery pack 1262, thereby making the heat conduction effect better. Connecting female connectors 1266 are threadedly connected to one outer wall of the cold branch pipe 1264 and the hot branch pipe 1265 at equal distances, and the male connectors 1267 are inserted into the inner parts of the connecting female connectors 1266. One end of the male connector 1267 is threadedly connected to a fixing frame 12671, and a push rod 12672 is welded inside the fixing frame 12671. One end of the male connector 1267 away from the fixing frame 12671 is integrally formed with an insertion pipe 12673 and a conduit 12675, and a clamping ring 12674 is integrally formed on the side outer wall of the insertion pipe 12673. One end of the connecting female connector 1266 is threadedly connected to a top frame 12661, and a spring 12662 is installed on one outer wall of the top frame 12661 through screws. One end of the spring 12662 is inserted with a piston 12663. A throat 12664 is integrally formed inside the connecting female connector 1266, and the piston 12663 is in contact with the throat 12664. A slot 12665 is formed on one outer wall of the connecting female connector 1266, and a clamping groove 12666 is formed on the side inner wall of the slot 12665. The insertion pipe 12673 is inserted into the slot 12665, and the clamping ring 12674 is clamped in the clamping groove 12666. The conduit 12675 is inserted into the throat 12664, and the push rod 12672 is in contact with the piston 12663.

[0036] The connecting female connector 1266 and the male connector 1267 adopting the above technical solution are used to connect the cold branch pipe 1264, the hot branch pipe 1265 and the cold plate 1263. When a certain cold plate 1263 fails, the maintenance personnel only need to directly pull out the cold plate 1263. At this time, the piston 12663 in the connecting female connector 1266 will block the throat 12664, preventing the coolant from leaking. Then, maintenance, inspection and replacement can be carried out, making the maintenance more convenient and fast.

[0037] Further, reference can be made to Figure 10, the liquid cooling system 3 includes a housing 31. Inside the housing 31, heat dissipation fins 38 are installed by screws, and a condensing pipe 39 is snap - fitted inside the heat dissipation fins 38. A compressor 32 is fixedly installed on the bottom inner wall of the housing 31 by bolts. A hot main pipe 33 is inserted into the input end of the compressor 32, and the hot main pipe 33 communicates with the hot branch pipe 1265. One end of the condensing pipe 39 is thread - connected to an expansion valve 35, and the other end of the condensing pipe 39 is inserted into the output end of the compressor 32. One end of the expansion valve 35 is thread - connected to a cold main pipe 34, and the cold main pipe 34 communicates with the cold branch pipe 1264. An air intake groove 36 is formed on one outer wall of the housing 31, and a dust - proof net is installed inside the air intake groove 36 by screws to prevent external dust from entering the interior. A plurality of heat dissipation fans 37 are fixedly installed on one outer wall of the housing 31 by bolts at equal intervals.

[0038] Embodiment Three: Please refer to Figures 1 to 11 As shown, on the basis of Embodiment Two, the present invention provides a technical solution: The fire - fighting system 2 includes a protective shell 21. Inside the protective shell 21, a plurality of carbon dioxide fire extinguishers 22 are fixedly installed by bolts for extinguishing fires for the battery pack 1262, and the output ends of the carbon dioxide fire extinguishers 22 penetrate into the interiors of the control room 11 and the energy storage room 12. A controller 23 is fixedly installed inside the protective shell 21 by bolts. A plurality of smoke sensors 24 are fixedly installed on the top inner walls of the control room 11 and the energy storage room 12 by bolts for monitoring fire conditions, and the smoke sensors 24 are electrically connected to the controller 23.

[0039] Adopting the above - mentioned technical solution, for the fire - fighting system 2, when a fire occurs due to a malfunction inside the device, the smoke sensor 24 of the fire - fighting system 2 can quickly detect it, and then the controller 23 controls the carbon dioxide fire extinguisher 22 to start, directly performing fire - extinguishing operations on the area where the fire occurs, without the need for operators to take risks and enter the interior of the device for fire - extinguishing, which is safer and more convenient.

[0040] Furthermore, refer to Figure 2 , a transformer bank 113 and a PSC complete set of equipment 114 are fixedly installed on the bottom inner wall of the control room 11 by bolts, and a lighting lamp 111 and a camera 112 are fixedly installed on the top inner wall of the control room 11 by bolts. The lighting lamp 111 can provide a certain amount of lighting for the interior of the device, and the camera 112 can be used to monitor the devices inside.

[0041] Working principle and usage process of the present invention: When the device is working, each battery rack 126 is separated by a fireproof wall 123, a fireproof door 124 and a vacuum glass door 127, and is located inside a separate space area. The compressor 32 sends the low-temperature and low-pressure coolant into the refrigerant tank 12631 of the cold plate 1263 through the cold main pipe 34, the cold branch pipe 1264, the connecting female nozzle 1266 and the connecting male nozzle 1267. The cold plate 1263 is in close contact with the battery pack 1262, and the heat inside the relatively high-temperature battery pack 1262 will flow to the coolant inside the cold plate 1263, thereby increasing the temperature of the coolant. Then the coolant enters the inside of the compressor 32 through the heat branch pipe 1265 and the heat main pipe 33, is compressed into a high-temperature and high-pressure state, and is sent into the inside of the condenser pipe 39. When the high-temperature and high-pressure coolant moves inside the condenser pipe 39, the heat inside the coolant will flow to the relatively low-temperature heat dissipation fins 38. Then the heat dissipation fan 37 drives the air flow to take away the temperature inside the heat dissipation fins 38, so that the coolant inside the condenser pipe 39 becomes a low-temperature state again. Finally, the coolant will enter the inside of the cold main pipe 34 through the expansion valve 35 to complete the cycle; when a certain cold plate 1263 fails, the operator directly pulls out the cold plate 1263 for maintenance. At this time, the connecting male nozzle 1267 of this cold plate 1263 leaves the corresponding connecting female nozzle 1266, and the piston 12663 of the connecting female nozzle 1266 will seal the throat 12664 under the push of the spring 12662. At this time, the coolant will not enter the inside of the throat 12664 and then spray out. After the maintenance and replacement are completed, the operator inserts the cold plate 1263 into the battery rack 126 again for reset. At this time, the ejector rod 12672 of the connecting male nozzle 1267 will push the piston 12663 inside the connecting female nozzle 1266 away from the throat 12664. Then the conduit 12675 is inserted into the throat 12664, and the insertion tube 12673 is inserted into the slot 12665, so as to reliably connect the connecting female nozzle 1266 and the connecting male nozzle 1267, and the coolant enters the inside of the cold plate 1263 through the throat 12664 again.
