Description

Technical Field

[0001] The present invention relates to the technical field of integrated cabinets, and more specifically, to a multifunctional integrated liquid-cooled energy storage integrated cabinet. Background Art

[0002] Liquid-cooled energy storage cabinet refers to a cabinet device that uses liquid cooling technology to manage energy storage equipment. This cabinet is usually used in energy storage systems, such as battery energy storage systems or supercapacitor energy storage systems, to store electrical energy for backup or to balance grid loads. The working principle of the liquid-cooled energy storage cabinet is to use the flow of coolant to remove the heat generated by the energy storage equipment during operation, thereby cooling the energy storage equipment. This cooling method is more efficient than air cooling, and can more effectively control the temperature of the equipment, thereby improving the operating efficiency and service life of the equipment.

[0003] The liquid cooling plate is the core function end of liquid cooling in the liquid-cooled energy storage cabinet. It is attached to the energy storage battery, and the coolant circulating in it takes away the heat generated by the energy storage battery during operation. In the existing liquid-cooled energy storage cabinet, due to limited installation space and the need to keep the coolant flow circulating, the combination of the liquid cooling plate and the battery module is stacked. In this way, when the liquid cooling plate plays a heat dissipation role, only the upper and lower surfaces of the energy storage battery are in contact with the liquid cooling plate, and the side of the energy storage battery cannot be cooled, which will cause local overheating, thereby affecting the overall performance and life of the battery. The overheated side may increase the risk of heat accumulation, reduce battery efficiency, and may accelerate aging.

[0004] Therefore, in the current related technologies, there is a certain gap in the field of gain improvement of cooling parts, and it is necessary to improve the balance of the cooling effect on the energy storage part. Summary of the invention

[0019] The beneficial effects of the present invention are:

[0020] The liquid cooling module in the present invention has the function of cooling the upper and lower planes and the surrounding sides of the battery module. The cooling of the upper and lower planes of the battery module is achieved by an attached cooling piece. A part of the coolant flowing in the first branch water pipe is diverted to the output pipe through the connecting pipe, sprayed out by the nozzle, and covered the left and right side surfaces and the back side of the battery module. The battery module is contact cooled by direct spraying, and then under the action of its own gravity, most of the coolant flows downward along the collecting channel, enters the collection box, and flows back to the second main water pipe through the collection pipe. This cycle is repeated to achieve the effect of continuously cooling the surrounding sides of the battery module.

[0021] In the spray-type cooling parts, in order to ensure that the battery modules in each layer can be sprayed with coolant, the motor is turned on while the output pipe is spraying, driving the screw to rotate, thereby driving the slide to slide back and forth up and down, that is, driving the output pipe to slide back and forth up and down so that the coverage of the coolant sprayed by the nozzle is changed from a fixed form to a movable form, significantly increasing its coverage range, so as to achieve the effect of cooling the surrounding sides of the battery modules in each layer.

[0022] The temperature sensor is electrically connected to the motor. Several temperature sensors monitor the operating temperature of the corresponding battery modules. Once the temperature of a battery module rises beyond the normal range and needs emergency cooling, the motor can be driven to rotate, the output tube can be moved to the corresponding battery module, and then the motor can be stopped, so that the nozzle can continue to spray and cool the battery module in this part until its temperature returns to the normal range, thereby playing the role of emergency fire fighting.

[0023] In the cleaning component, a double-layer filter is used to filter the impurities carried in the coolant concentrated on one side of the collection box. The filter is then set into a conveyor belt form through rollers and a rotating shaft. Under the action of the transmission part, the output of the motor is transmitted to the rotating shaft to enable the filter to move. Then, since a fixed scraper bar is set in contact with the filter, the impurities deposited on the filter can be removed by the scraper bar and collected on the side of the dirt collecting part, ensuring that the filter can maintain its filtering function in a maintenance-free state.

DETAILED DESCRIPTION

[0034] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that the discussion of these implementations is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Various examples may omit, replace, or add various processes or components as needed. In addition, the features described in some examples may also be combined in other examples.

[0035] At least one embodiment of the present invention discloses a multifunctional integrated liquid cooling energy storage cabinet. Figure 1 - Fig. 9As shown, it includes a cabinet 1, a battery module 2, an energy storage converter 3, a cluster management module 4 and a liquid cooling module 5. The battery module 2, the energy storage converter 3, the cluster management module 4 and the liquid cooling module 5 are all placed in the internal space of the cabinet 1. The liquid cooling function part of the liquid cooling module 5 is laminated with the battery module 2. The energy storage converter 3 and the cluster management module 4 are electrically connected to the battery module 2.

[0036] refer to Figure 2 The liquid cooling module 5 includes a water cooler 51, a first main water pipe 52, a second main water pipe 53, an attached cooling element 54, a spray cooling element 55 and a cleaning component 56. The water cooler 51 is connected with the attached cooling element 54 and the spray cooling element 55 through the first main water pipe 52 and the second main water pipe 53. The coolant flows to the attached cooling element 54 and the spray cooling element 55 through the first main water pipe 52, and then flows back to the water cooler 51 through the second main water pipe 53 for cooling, forming a cycle. The cleaning component 56 filters the coolant refluxed from the spray cooling element 55 and cleans the filtering part.

[0037] refer to Figure 4 The attached cooling member 54 includes a first branch water pipe 541, a liquid cooling plate 542 and a second branch water pipe 543. The first main water pipe 52 is connected to a plurality of first branch water pipes 541 at equal intervals, the second main water pipe 53 is connected to a plurality of second branch water pipes 543 at equal intervals, and a liquid cooling plate 542 is connected between the first branch water pipe 541 and the second branch water pipe 543 located on the same horizontal plane, and the liquid cooling plate 542 is in contact with the plane of the battery module 2 in the vertical direction;

[0038] The cooling liquid output by the spray cooling member 55 covers the side of the battery module 2 in a spraying posture, is collected at the bottom of the battery module 2 and then flows back into the second main water pipe 53 . The output portion of the spray cooling member 55 reciprocates up and down relative to the battery module 2 .

[0039] The liquid cooling module 5 in the present invention has the function of cooling the upper and lower planes and the surrounding sides (except the front side that needs to be connected to the electrical structure) of the battery module 2. Specifically:

[0040] Cooling of the upper and lower planes of the battery module 2 is achieved through an attached cooling member 54. In the attached cooling member 54, the coolant in the water cooler 51 enters the first main water pipe 52, is diverted into the first branch water pipe 541, and then enters the liquid cooling plates 542 of each layer. Since the liquid cooling plates 542 are attached to the upper and lower surfaces of the battery module 2, the high temperature generated when the battery module 2 is working is transferred to the coolant flowing through the liquid cooling plates 542 through heat transfer, so that the upper and lower surfaces of the battery module 2 are cooled. After flowing out, the coolant in each layer of the liquid cooling plates 542 is concentrated in the second main water pipe 53, and flows back to the water cooler 51 through the second main water pipe 53, forming a circulation of the coolant, thereby achieving the effect of continuously cooling the upper and lower surfaces of the battery module 2.

[0041] Cooling of the battery module 2 is achieved by spray cooling element 55, see Figure 5 and Figure 6 The spray cooling element 55 includes a motor 551, a frame 552, a screw 553, a slide 554, an output pipe 555, a nozzle 556, a connecting pipe 557, a collection box 558 and a collection pipe 559. The cabinet 1 is provided with a motor 551, a frame 552 is provided on one side of the motor 551, a screw 553 is rotatably installed in the frame 552, the end of the screw 553 extending out of the frame 552 is fixedly connected to the output end of the motor 551, and the screw 553 is matched with a slide 554 slidably provided with the frame 552. An output pipe 555 is fixedly installed on one side of the slide 554, and a plurality of nozzles 556 are installed on the output pipe 555. The output pipe 555 is connected to the first main water pipe 52 through a connecting pipe 557. A collecting channel 5420 is provided on the liquid cooling plate 542. The collecting channel 5420 is connected in the vertical direction. A collecting box 558 is installed in the cabinet 1. The collecting channel 5420 at the bottom is connected to the top of the collecting box 558. The bottom of the collecting box 558 is connected to the second main water pipe 53 through a collecting pipe 559.

[0042] The output pipe 555 is U-shaped, and the atomized cooling liquid sprayed from the nozzle 556 covers the left and right side surfaces and the back side of the battery module 2;

[0043] The connecting pipe 557 is in the shape of a bellows, which can ensure the transmission of the coolant when the output pipe 555 moves.

[0044] In the spray cooling component 55, a part of the coolant flowing in the first branch water pipe 541 is diverted to the output pipe 555 through the connecting pipe 557, and is sprayed out by the nozzle 556 in atomized form to cover the left and right side surfaces and the back side of the battery module 2, thereby contact cooling the battery module 2 through direct spraying. Then, under the action of its own gravity, most of the coolant flows downward along the collecting channel 5420, enters the collecting box 558, and flows back to the second main water pipe 53 through the collecting pipe 559, and circulates in this way to achieve the effect of continuously cooling the surrounding side of the battery module 2.

[0045] A first water pump 520 is provided at the connection between the connecting pipe 557 and the first branch water pipe 541, and a second water pump 530 is provided at the connection between the collecting pipe 559 and the second branch water pipe 543. Through the pumping of the first water pump 520, the coolant rises smoothly and enters the output pipe 555. Similarly, through the pumping of the second water pump 530, the coolant can rise and flow back along the second branch water pipe 543 smoothly after flowing out of the collecting pipe 559.

[0046] Furthermore, in the spray cooling part 55, in order to ensure that the battery modules 2 in each layer can be sprayed with coolant, the motor 551 is turned on while the output tube 555 is spraying, driving the screw 553 to rotate, thereby driving the slide 554 to slide back and forth up and down (control the forward and reverse rotation of the motor 551 or use the reciprocating screw 553 form), that is, driving the output tube 555 to slide back and forth up and down so that the coverage of the coolant sprayed by the nozzle 556 is changed from a fixed form to a movable form, which significantly increases its coverage range, thereby achieving the effect of cooling the surrounding sides of the battery modules 2 in each layer.

[0047] Furthermore, the spray cooling element 55 can also be used as an emergency fire fighting facility, specifically:

[0048] refer to Figure 2 and Figure 5 Each of the battery modules 2 is provided with a temperature sensor 200, which is electrically connected to the motor 551. A plurality of temperature sensors 200 monitor the operating temperature of the corresponding battery modules 2. Once the temperature of a battery module 2 rises beyond the normal range and requires emergency cooling, the motor 551 can be driven to rotate, and the output tube 555 can be moved to the corresponding battery module 2. Then the motor 551 is stopped, so that the nozzle 556 continuously sprays and cools the battery module 2 at this position until its temperature returns to the normal range, thereby playing the role of emergency fire fighting.

[0049] It should be specially noted that the above only mentions the method of realizing the emergency fire-fighting function. When using it, you can flexibly select existing technical facilities such as PLC controller (to convert between temperature signal and start and stop signal of motor 551), visual detection device (to improve the accuracy of the moving position of output tube 555) according to the usage scenario.

[0050] A limiting rod 5520 flush with the screw rod 553 is installed in the frame body 552 , and the slide 554 is slidably matched with the limiting rod 5520 , and the limiting rod 5520 is used to limit the reciprocating sliding movement of the slide 554 .

[0051] Although the spray cooling has the advantages of fast cooling speed and wide range of action, the directly sprayed coolant is easily contaminated with impurities such as dust in the surrounding environment and on the surface of the battery module 2. If it is not cleaned in time, the coolant contaminated with impurities will circulate, which will easily cause blockage of the coolant pipeline. For this reason, the present invention is provided with a cleaning component 56, specifically:

[0052] refer to Figure 7 and Figure 8 The cleaning assembly 56 includes a first bracket 561, a roller 562, a rotating shaft 563, a transmission member 564, a second bracket 565, a scraper 566, a dirt collecting member 567 and a filter 568. The first bracket 561 is symmetrically fixedly arranged in the cabinet 1, and a rotating shaft 563 is rotatably installed on the first bracket 561. A roller 562 is fixedly installed on the rotating shaft 563. The filter 568 moves in a conveyor belt manner between the rollers 562. The upper and lower layers of the filter 568 are slidably interlaced with the collecting box 558 near the collecting channel 5420. One end of the rotating shaft 563 cooperates with the motor 551 through the transmission member 564. The second bracket 565 is symmetrically fixedly arranged in the cabinet 1. A scraper 566 is fixed on the second bracket 565. One side of the scraper 566 is in extrusion contact with the upper surface of the filter 568, and the other side is provided with a dirt collecting member 567.

[0053] In the cleaning component 56, a double-layer filter 568 is used to filter the impurities carried in the coolant concentrated on one side of the collection box 558, and then the filter 568 is set in the form of a conveyor belt through the roller 562 and the rotating shaft 563. Under the action of the transmission member 564, the output of the motor 551 is transmitted to the rotating shaft 563, so that the filter 568 can move. Then, since a fixed scraper bar 566 is set to contact the filter 568, the impurities deposited on the filter 568 can be removed by the scraper bar 566 and collected on the side of the dirt collecting member 567, ensuring that the filter 568 can maintain its filtering function in a maintenance-free state.

[0054] refer to Figure 8More specifically, the transmission member 564 includes a vertical shaft 5641, a synchronous member 5642, a first bevel gear 5643 and a second bevel gear 5644. The vertical shaft 5641 is rotatably installed in the cabinet 1, and the vertical shaft 5641 and the output shaft of the motor 551 rotate synchronously through the synchronous member 5642. The first bevel gear 5643 is fixedly installed at the end of the vertical shaft 5641, and the second bevel gear 5644 is fixedly installed at the end of the rotating shaft 563. The first bevel gear 5643 is vertically meshed with the second bevel gear 5644.

[0055] The synchronous member 5642 is made of a rotating wheel and a belt, which belongs to the existing technical means and will not be elaborated here.

[0056] The rotation of the output shaft of the motor 551 is transmitted to the vertical shaft 5641 side through the synchronous member 5642, so that the vertical shaft 5641 rotates, and through the cooperation of the first bevel gear 5643 and the second bevel gear 5644, the rotating shaft 563 is driven to rotate, thereby rotating the roller 562 on one side, driving the filter 568 to move.

[0057] refer to Fig. 9 The dirt collecting member 567 includes a first transfer box 5671, a second transfer box 5672, a leakage hole 5673, a first conduit 5674, a dirt collecting box 5675 and a second conduit 5676. One side of the scraper strip 566 is in a triangular shape and contacts the filter screen 568, and the other side is fixedly connected with the first transfer box 5671 and the second transfer box 5672. The first transfer box 5671 is provided with a leakage hole 5673, and the leakage hole 5673 is connected to the second transfer box 5672 through the first conduit 5674. A dirt collecting box 5675 is provided at the bottom of the second transfer box 5672, and the dirt collecting box 5675 is connected to the second transfer box 5672 through the second conduit 5676.

[0058] In the dirt collecting part 567 , impurities accumulated on the filter screen 568 enter the first transfer box 5671 and the second transfer box 5672 along the surface of the scraper bar 566 after being scraped by the scraper bar 566 , and are collected in the dirt collecting box 5675 along the vertical direction through the leakage hole 5673 and the second conduit 5676 .

[0059] The above describes an embodiment of the present invention, but this embodiment is not limited to the above-mentioned specific implementation mode. The above-mentioned specific implementation mode is merely illustrative and not restrictive. Under the guidance of this embodiment, ordinary technicians in this field can also make more forms of equivalent embodiments, all of which are within the protection of this embodiment.
