Description

Technical Field

[0001] This invention belongs to the field of energy storage cabinet technology, and in particular relates to a dual-mode heat dissipation energy storage cabinet. Background Technology

[0002] As the basic unit of energy storage equipment, energy storage cabinets typically house battery modules and control modules. The battery modules generate a lot of heat when storing and releasing electrical energy. In order to ensure that the battery modules, control modules, and other electrical equipment inside the energy storage cabinet can operate normally and efficiently, it is necessary to dissipate the heat inside the energy storage cabinet.

[0003] Air cooling is one of the commonly used heat dissipation methods in the energy storage industry. It involves cooling air through an air duct and blowing it onto the battery surface to lower the battery temperature. However, air cooling suffers from a sharp drop in heat dissipation efficiency at high temperatures. To address this issue, existing technologies have developed dual-mode heat dissipation solutions that combine air cooling and liquid cooling. For example, CN120473600B discloses a ventilated heat dissipation type energy storage battery cabinet. The cabinet has a first heat dissipation mechanism for air cooling and a second heat dissipation mechanism for water cooling.

[0004] The aforementioned air duct design is fixed, and the exhaust vents cannot be opened and closed flexibly, resulting in low airflow organization efficiency and insufficient utilization of cold air. Furthermore, liquid cooling systems mostly adopt a uniform flow distribution, which cannot be precisely adjusted according to the temperature differences of different battery layers, which may cause over-cooling or insufficient heat dissipation. Summary of the Invention

[0005] The purpose of this invention is to provide a dual-mode heat dissipation energy storage cabinet. By combining the air ducts in the side frame with the cooling flow channels in the support plate, and with the switchable exhaust port structure, the problem of low airflow organization efficiency caused by the inability to flexibly open and close the existing exhaust ports is solved.

[0012] Furthermore, a flow regulating mechanism is provided between the horizontal sections of the cooling channel and the outlet pipe, respectively connected to both; the flow regulating mechanism includes a square tube body, the two ends of which are closed, and a partition plate is provided on one inner wall of the square tube body, the partition plate dividing the interior of the square tube body on both sides to form an inlet chamber and an outlet chamber, a gap is left between the top edge of the partition plate and the top wall of the square tube body to form an overflow channel; an inlet hole and an outlet hole are respectively opened on the side walls of the square tube body on both sides of the partition plate; the inlet hole and the outlet hole are respectively connected to the cooling channel and the outlet pipe; during installation, the side wall of the square tube body with the partition plate is located at the bottom.

[0013] Furthermore, a solenoid valve is installed on the pipeline connecting the water outlet pipe and the water outlet hole; or a sealing structure for sealing the water inlet / outlet hole is provided on the inner wall of the square tube.

[0017] The present invention has the following beneficial effects:

[0018] 1. This invention achieves directional airflow by combining the air duct inside the side frame with the cooling flow channel inside the support plate, along with a switchable exhaust port structure. When air enters through one side air duct, the exhaust port away from the air inlet side opens, forming a directional airflow that runs through the battery module, effectively preventing airflow short circuits.

[0019] 2. This invention effectively overcomes the drawback of traditional air-cooling systems, which suffer from a sharp drop in heat dissipation efficiency under high-temperature environments, by organically combining air cooling and liquid cooling modes. Under extreme environmental conditions, the liquid cooling system can independently undertake the main heat dissipation task, ensuring that the battery module operates within a safe temperature range.

[0020] 3. The flow regulation mechanism of this invention controls the flow rate of coolant in the cooling channels of each support plate to achieve independent temperature management of different battery modules. When the temperature sensor of a certain layer detects an abnormally high temperature, the processor can instruct the flow regulation mechanism of that layer to increase the opening to enhance heat dissipation in a targeted manner; otherwise, the opening is reduced to save energy. This design solves the problem of uneven flow distribution in traditional liquid cooling systems and avoids local overheating or overcooling.

[0021] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0038] 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.

[0039] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0040] Example 1: Please refer to Figure 1-3As shown, the present invention is a dual-mode heat dissipation energy storage cabinet, including a cabinet body 1. Inside, on both sides, are battery supports composed of two side frames 12 and support plates 13. Multiple support plates 13, distributed from top to bottom, are connected between the two side frames 12 to support energy storage battery modules 100. The support plates are made of aluminum alloy with an insulating coating on the surface. A maintenance door 14 is hinged to the front of the cabinet body 1, and the maintenance door 14 is equipped with an observation window and a lock. The support plates divide the cabinet space into multiple independent heat dissipation layers, with the bottom of each battery module directly contacting the support plate 13. The bottom of the support plate 13 is 1-2 cm from the top side of the energy storage battery module 100 below it, forming a heat dissipation gap between the bottom of the support plate 13 and the top side of the energy storage battery module 100.

[0041] In order to improve the heat dissipation effect of the energy storage battery module 100, the present invention provides a water cooling system and an air cooling system, while the heat dissipation fins are detachably installed on the outer surface of the energy storage battery module 100 by bolts or clips.

[0042] The heat dissipation fins are made of aluminum alloy and coated with a nano-thermal conductive coating. Thermal grease is applied between the substrate of the heat dissipation fins and the contact surface between the substrate of the heat dissipation fins and the energy storage battery module 100. The spacing between the heat dissipation fins is 3-8mm and the thickness is 0.5-1.5mm.

[0043] Among them, such as Figure 9-10 The side frame 12 includes two parallel vertical beams 120, the bottom of which is fixed to the inner bottom side of the cabinet 1. Multiple horizontal beams 121 are connected between the two vertical beams 120, and any one of the horizontal beams 121 is located above the energy storage battery module 100. Both the horizontal beams 121 and the vertical beams 120 are square tubes, and the interiors of the horizontal beams 121 and the vertical beams 120 are connected to form an air duct. Air vents are provided on the side of the horizontal beams 121 and the vertical beams 120 that are close to the energy storage battery module 100. The air-cooled heat dissipation system is composed of an air pump 65 connected to the air duct.

[0044] The inner wall of the square tube is smoothed with a roughness Ra≤3.2μm, which reduces airflow resistance, reduces wind pressure loss by about 15%, and improves air supply efficiency.

[0045] When air is pumped to one side of the air duct by the air pump 65, the other side of the air duct is closed. In order to facilitate the formation of airflow inside the cabinet 1, that is, when cold air is sent into the cabinet 1 by the air pump 65 and the air duct, it is necessary to expel the hot air inside the cabinet 1 in time. Based on this, the present invention provides exhaust vent structures on both sides of the cabinet 1, and the exhaust vent structures can be opened and closed.

[0046] That is, when air is supplied to one side of the air duct by the air pump 65, the other side of the air duct is closed. At the same time, the drive mechanism 5 controls the opening and closing of the exhaust port structure. The exhaust port structure away from the air inlet side is opened, and the exhaust port structure near the air inlet side is closed. At this time, the cold air discharged from the air duct forms a directional airflow at the cabinet door 1. The cold air blows across the outer periphery of the energy storage battery module 100 and carries away the heat. The air pump 65 adopts a centrifugal fan with a rated power of 200W and a maximum air volume of 300m³ / h.

[0047] Specifically, each side panel on both sides of the cabinet 1 includes two parallel side panel bodies, which are welded together by a frame between them. The two side panel bodies and the frame are welded together to form a movable cavity 10. The exhaust port structure includes a cover plate 103 disposed in the movable cavity 10. Slider blocks are provided on both side end faces of the cover plate 103. The inner wall of the movable cavity 10 is provided with a guide rail that cooperates with the slider. The guide rail is arranged vertically. The cover plate 103 can move up and down along the inner wall of the movable cavity 10 under the traction of the drive mechanism 5.

[0048] like Figure 9-10 To enable the opening and closing of the exhaust vent structure, the present invention provides a plurality of first rectangular openings 104 with equal spacing along the vertical direction on the baffle 103; the side plates located on both sides of the movable cavity 10 are respectively provided with second rectangular openings 101 and third rectangular openings 102; the dimensions of the second rectangular openings 101 and third rectangular openings 102 are adapted to the dimensions of the first rectangular openings 104, and the second rectangular openings 101 and third rectangular openings 102 are matched and aligned one by one, and when the baffle 103 moves to a specific position, the first rectangular openings 104 can be completely aligned with or completely misaligned with the second rectangular openings 101 and third rectangular openings 102; when the first rectangular openings 104 are aligned with the second rectangular openings 101, the exhaust vent structure is opened; when the baffle 103 moves to a position where the first rectangular openings 104 and second rectangular openings 101 are completely misaligned, the exhaust vent structure is closed.

[0049] To prevent dust and other environmental contaminants from entering the interior of cabinet 1 during air-cooling, filters are installed at the second rectangular opening 101 and / or the third rectangular opening 102. The filters are made of stainless steel mesh with a mesh size of 200 and are fixed by magnetic attraction. The removable filters facilitate cleaning and maintenance, preventing dust from clogging the air duct. To improve the sealing effect when the exhaust vent structure is closed, an annular sealing boss made of rubber is installed on the outer wall of the baffle 103. This annular sealing boss can fit against the inner wall of the outer side panel body to form a seal, and the size of the annular sealing boss is larger than that of the second rectangular opening 101. When the exhaust vent structure is closed, the annular sealing boss surrounds the periphery of the second rectangular opening 101.

[0050] like Figure 9-12To achieve automatic opening and closing of the exhaust vent structure, the drive mechanism 5 provided by this invention includes a telescopic module 50, a movable plate 52, and a traction rope 105. The telescopic module 50 uses a linear motor with a stroke of 100mm, a thrust of 50N, and a response time of ≤0.5s. The movable plate 52 is connected to the cabinet via a slider guide rail structure. The traction rope 105 is made of stainless steel wire rope with a diameter of 1mm, one end of which is fixed to the movable plate 52, and the other end passes over a fixed pulley and connects to the cover plate 103. When the telescopic module 50 pushes the movable plate 52 to move, the traction rope 105 drives the cover plate 103 to move up and down within the movable cavity 10, with a movement stroke of ±50mm.

[0051] Meanwhile, in order to facilitate installation and maintain the stable extension and retraction of the telescopic module 50, an L-shaped bracket 53 is also installed on the top of the side frame 12, and the top of the bracket 53 is connected to the inner top side of the cabinet 1; multiple first guide rods 521 are provided on the movable plate 52 to guide the bracket 53.

[0052] To selectively deliver the airflow generated by the air pump 65 into the corresponding air duct, and to coordinate with the opening and closing of the exhaust port structure, this invention connects an air intake control structure 51 between the mounting plate 54 and the movable plate 52. The air intake control structure 51 includes a cylindrical body 510, with connecting pipe 1 511 and connecting pipe 2 512 respectively connected to both ends of the cylindrical body 510. A sealing piston 513 is provided inside the cylindrical body 510, sliding along its inner wall. The sealing piston 513 uses a polyurethane sealing ring and fits tightly with the inner wall of the cylindrical body 510. A piston rod 515 and a second guide rod 514, penetrating the cylindrical body 510, are connected between the movable plate 52 and the sealing piston 513. The connecting pipe 2 512 is located between the connecting pipe 1 511 and the movable plate 52. The connecting pipe 1 511 is connected to the air pump 65, and the connecting pipe 2 512 is connected to the ventilation duct.

[0053] As shown in the figure, when the telescopic module 50 is in the retracted state, the movable plate 52 is located on the far left, and the piston rod 515 drives the sealing piston 513 to be located on the side away from the connecting pipe 512, completely blocking the air passage; the airflow generated by the air pump 65 enters the cylinder 510 only through the connecting pipe 511, but cannot flow to the air passage due to the obstruction of the sealing piston 513.

[0054] When the control telescopic module 50 pushes the movable plate 52 to the right, the piston rod 515 drives the sealing piston 513 to move to the right. When the sealing piston 513 moves between the connecting pipe 512 and the movable plate 52, the airflow generated by the air pump 65 enters the cylinder 510 through the connecting pipe 511. At this time, the airflow in the cylinder 510 enters the air duct through the connecting pipe 512.

[0055] Among them, an inlet pipe 2 and an outlet pipe 3 are respectively installed on the two side frames 12. The bottom end of the inlet pipe 2 is connected to the water pump 63, and the outlet pipe 3 is connected to the return pipe; for example Figure 4The inlet pipe 2 and outlet pipe 3 are made of copper pipe with an outer diameter of 15mm and a wall thickness of 1.5mm. The outer wall of the pipe is wrapped with 10mm thick insulation cotton. The inlet pipe 2 and outlet pipe 3 have the same structure, both of which are serpentine structures, each including multiple horizontal sections 21 and multiple vertical sections 20. The vertical sections 20 and horizontal sections 21 are alternately arranged, and the inlet pipe 2 is formed by bending a single pipe body.

[0056] like Figure 5 The support plate 13 is provided with several cooling channels 131, which are arranged side by side with equal gaps. The horizontal section 21 of the water inlet pipe 2 is provided with multiple quick connectors on its side wall, which are connected to the cooling channels 131 in the support plate 13 one by one. The cooling channels 131 and the horizontal section 21 of the water outlet pipe 3 are connected and connected.

[0057] like Figure 6 In order to adjust the heat dissipation effect of the energy storage battery module 100 on the corresponding layer, a flow regulation mechanism 4 is also provided between the cooling channel 131 and the horizontal section 21 of the water outlet pipe 3. The two sides of the flow regulation mechanism 4 are connected to the cooling channel 131 and the water outlet pipe 3 respectively.

[0058] Specifically, such as Figure 7 The flow regulating mechanism 4 includes a square tube 40, which is closed at both ends. The square tube 40 is made of stainless steel and has a size of 100mm×50mm×50mm. The interior is divided into an inlet chamber and an outlet chamber by a partition plate 41. The partition plate 41 has a height of 45mm and a 5mm overflow channel is reserved at the top. The overflow channel can balance the pressure when the flow changes suddenly and prevent water hammer effect.

[0059] like Figure 7 Water inlet holes 42 and water outlet holes 43 are respectively opened on the side walls of the square tube 40 located on both sides of the partition plate 41. The diameters of the water inlet holes 42 and water outlet holes 43 are 4mm and 12mm respectively, and they are located at the bottom of the water inlet chamber and the water outlet chamber respectively. The water inlet holes 42 and water outlet holes 43 are respectively connected to the cooling flow channel 131 and the water outlet pipe 3. During installation, the side wall of the square tube 40 with the partition plate 41 is located at the bottom.

[0060] Based on the above, in order to facilitate the control of the flow rate per unit time from the cooling channel 131 into the outlet pipe 3, the present invention can adjust the opening of the inlet hole 42 and / or the outlet hole 43 in actual use, thereby adjusting the cooling effect of the support plate 13.

[0061] Method 1: Install a solenoid valve on the pipeline connecting the water outlet pipe 3 and the water outlet hole 43, and adjust the opening of the water outlet hole 43 by adjusting the opening of the solenoid valve.

[0062] Method 2: For example Figure 8A sealing structure for sealing the water inlet 42 is provided on the inner wall of the square tube 40. The sealing structure includes a sealing plate 44, which can move along the height direction of the partition plate 41. A guide post 45 is connected between the opposite side walls of the square tube 40, and the guide post 45 passes through the sealing plate 44. Multiple L-shaped movable rods 46 are connected to one side of the sealing plate 44. The top of the movable rods 46 passes through the square tube 40 and extends to the outside of the square tube 40. A movable beam 47 is connected to the top of the movable rods 46. The sealing plate 44 is made of polytetrafluoroethylene. The telescopic module two uses a stepper motor with a stroke of 5mm, a thrust of 10N, and an accuracy of 0.1mm. The sealing plate 44 moves up and down under the drive of the telescopic module two to adjust the opening of the water inlet 42 or the water outlet 43. The opening adjustment range is 0-4mm.

[0063] In Example 2, based on Example 1, in order to facilitate the injection of cold water into the cooling channel 131 of each support plate 13 by the water pump 63 during use, a water storage tank 11 is also provided. The top of the water inlet pipe 2 is connected to the bottom of the water storage tank 11 to prevent the water pumped out by the water pump 63 from failing to fill the cooling channel 131 of each support plate 13 when the water pressure is insufficient.

[0064] A liquid level sensor 61 and an exhaust pipe are installed inside the water storage tank 11, and an exhaust valve 64 is installed on the exhaust pipe; the system working pressure is kept stable through the exhaust valve 64.

[0065] To achieve dual-mode collaboration and precise zoned temperature control; such as Figure 13 The invention also includes a processor, which is an ARM Cortex-M4 core microcontroller with a main frequency of 100MHz. The processor is connected to a liquid level sensor 61, an air pump 65 and a water pump 63, an exhaust valve 64, a drive mechanism 5, a flow regulation mechanism 4, and a temperature sensor 62. The temperature sensor 62 is a DS18B20 digital temperature sensor with a measurement accuracy of ±0.5℃. It is installed on the side and top of each layer of energy storage battery module 100, with two sensors arranged on each layer. The air pump 65 and the water pump 63 are controlled to start and stop via a relay module, and the drive mechanism 5 and the flow regulation mechanism 4 are controlled via a PWM signal.

[0066] System initialization: All sensors collect data; air-cooled and liquid-cooled heat dissipation systems are in standby mode.

[0067] When at least one temperature sensor 62 detects a temperature higher than 30°C, the air-cooled heat dissipation system is activated, and the liquid-cooled heat dissipation system is put into standby mode.

[0068] When at least one temperature sensor 62 detects a temperature higher than 35°C, the air-cooled heat dissipation system and the liquid-cooled heat dissipation system are activated, and the flow regulation mechanism for each floor is opened to 50%.

[0069] When at least one temperature sensor 62 detects that the temperature of a certain layer exceeds 40°C, the opening of the flow regulation mechanism for that layer is increased to 75%; if the overall temperature exceeds 45°C, the opening of the flow regulation mechanism for that layer is increased to 100%.

[0070] When all temperature sensors 62 detect a temperature below 30°C, the air-cooled and liquid-cooled heat dissipation systems are put into standby mode.

[0071] It is known that the following instruction manual is attached. Figure 5-8 The arrows for 10 and 10 indicate the direction of fluid flow.
