Description

Technical Field

[0001] The present invention relates to an energy storage cabinet, and particularly to a structure of an energy storage cabinet with efficient cooling. Background Art

[0002] With the rapid development of information technology, the demand for energy storage devices in places such as data centers and communication base stations is increasing day by day. As one of the key components, the energy storage cabinet integrates a large number of electronic components and battery modules inside, and these components will generate a large amount of heat during operation. If this heat cannot be dissipated in a timely and effective manner, it will cause the temperature inside the energy storage cabinet to rise, thereby affecting the working efficiency and lifespan of the electronic components, and even possibly leading to equipment damage or safety accidents in severe cases.

[0003] Insufficiency of traditional heat dissipation design: Many energy storage cabinets adopt traditional heat dissipation methods, such as forced ventilation with a single fan or simple natural convection heat dissipation. This method is difficult to meet the demand for dissipating a large amount of heat generated by high-power density energy storage systems.

[0004] Unbalanced thermal management: Due to the complex layout inside the energy storage cabinet, the distances between heat sources at different positions and the heat dissipation devices are different, resulting in overheating in some areas, while there may be excessive heat dissipation in other areas, leading to low overall heat dissipation efficiency.

[0005] Therefore, there is an urgent need to develop a structure of an energy storage cabinet with efficient cooling that can conduct comprehensive heat dissipation. Summary of the Invention

[0006] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a structure of an energy storage cabinet with efficient cooling that can conduct comprehensive heat dissipation.

[0007] A structure of an energy storage cabinet with efficient cooling includes a mounting support, a battery energy storage cabinet, and a cooling component. The battery energy storage cabinet is placed on the top of the mounting support from bottom to top, and a cooling component is arranged on the top of the uppermost battery energy storage cabinet. The cooling component is connected to the battery energy storage cabinet. The cooling component includes a water tank, a heat dissipation aluminum plate, a water pipe, and a heat conduction copper pipe. The water tank is installed on the top of the uppermost battery energy storage cabinet. Heat dissipation aluminum plates are arranged at the bottom of the battery energy storage cabinet. Heat conduction copper pipes are embedded in the heat dissipation aluminum plates. The ends of the heat conduction copper pipes penetrate out from the left side of the heat dissipation aluminum plates. There are two water pipes on the water tank, which are used for water inlet and outlet. The pipe for water inlet is connected to the inlet of the heat conduction copper pipe, and the pipe for water outlet is connected to the outlet of the heat conduction copper pipe. The heat dissipation aluminum plate is composed of an aluminum shell, an aluminum cover plate, a diversion heat dissipation fin, and an L-shaped connecting pipe. The heat conduction copper pipe is installed in the aluminum shell, and the aluminum cover plate covers the aluminum shell and is hermetically connected to it. At least two groups of diversion heat dissipation fins are arranged at the bottom of the aluminum cover plate. An L-shaped connecting pipe is connected between the aluminum shell and the two water pipes.

[0008] Optionally, it further includes branch pipes, a heat conducting plate, and a second violent fan. The water pipe between two adjacent heat conducting copper pipes is composed of three branch pipes. The branch pipes divide the flowing water into small streams. A heat conducting plate is arranged on the installation box at the branch pipe. The branch pipe is stuck in the heat conducting plate. A second violent fan is installed on the water tank above the water pipe.

[0009] Optionally, through holes are vertically formed on the heat conducting plate.

[0010] Optionally, the shape of the part embedded inside the heat dissipation aluminum plate is S-shaped.

[0011] Optionally, the installation support includes a base, wheels, and a connecting plate. Wheels are symmetrically arranged at the bottom of the base. A connecting plate is arranged on the left side of the base. The connecting plate is used to connect the battery energy storage cabinet. Every two adjacent battery energy storage cabinets are fixedly connected through the connecting plate.

[0012] Optionally, the battery energy storage cabinet includes an installation box, a net plate, a first violent fan, and a battery placement plate. The battery placement plate is fixedly connected inside the installation box through bolts. The battery is fixed on the battery placement plate through bolts. A net plate is fixedly connected to the left side surface of the installation box. A first violent fan is fixedly connected to the right side surface of the net plate.

[0013] Optionally, the battery energy storage cabinet further includes a positioning convex block and a positioning concave block. The fitting surfaces of two adjacent installation boxes are respectively provided with the positioning convex block and the positioning concave block. When the two installation boxes are placed together, the positioning convex block is inserted into the positioning concave block for installing and positioning two adjacent battery energy storage cabinets.

[0014] Optionally, the battery energy storage cabinet further includes a handle. Handles are embedded on both the front and back sides of the installation box.

[0015] Optionally, a strip-shaped hole is formed on the right side surface of the installation box. The strip-shaped hole and the net plate allow air to form convection.

[0016] Optionally, the battery energy storage cabinet further includes an aluminum strip. The aluminum strip is inclined on the part of the right wall of the installation box corresponding to the strip-shaped hole. The aluminum strip is installed in a downward inclination.

[0017] The beneficial effects of the present invention are as follows: By controlling the operation of the first violent fan, the present invention inhales the outside air through the strip-shaped hole, then passes through the battery to dissipate heat from the battery, and the hot air is discharged through the net plate. Through the provided aluminum strip, which is installed in a downward inclination, when the air passes through the aluminum strip, the aluminum strip cools the air, making the temperature of the air entering for heat dissipation lower, better dissipating heat from the battery. At the same time, because the aluminum strip blocks the inside of the strip-shaped hole, when there are impurities in the air, the aluminum strip can block the impurities. When it is necessary to further improve the heat dissipation effect, the heat of the battery is conducted to the heat conducting copper pipe through the heat dissipation aluminum plate. When the water tank works, the water pipe of the heat conducting copper pipe dissipates heat, enabling the heat dissipated by the battery to be quickly taken away. Brief Description of the Drawings

[0033] The principle and structure of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0034] Embodiment: A structure of an energy storage cabinet with efficient cooling, as Figures 1 - 8 shown, includes an installation support 1, a battery energy storage cabinet 2 and a cooling component 3. The battery energy storage cabinet 2 is placed on the top of the installation support 1 from bottom to top, and the cooling component 3 is arranged on the top of the uppermost battery energy storage cabinet 2, and the cooling component 3 is connected to the battery energy storage cabinet 2.

[0035] As Figure 2 shown, the installation support 1 includes a base 11, wheels 12 and a connecting plate 13. The wheels 12 are symmetrically arranged at the bottom of the base 11 through bolts, and the wheels 12 are used to drive the whole device to move. A connecting plate 13 is arranged on the left side of the base 11, and the connecting plate 13 is used to connect the battery energy storage cabinet 2, and every two adjacent battery energy storage cabinets 2 are fixedly connected through the connecting plate 13.

[0036] As Figures 3 - 6As shown in the figure, the battery energy storage cabinet 2 includes an installation box 21, a positioning convex block 22, a positioning concave block 23, a handle 24, a mesh plate 25, a first violent fan 26, a battery placement plate 27, and an aluminum strip 28. The mating surfaces of two adjacent installation boxes 21 are respectively provided with a positioning convex block 22 and a positioning concave block 23. When the two installation boxes 21 are placed together, the positioning convex block 22 is inserted into the positioning concave block 23 for installing and positioning two adjacent battery energy storage cabinets 2. The handle 24 is embedded on both the front and rear sides of the installation box 21, and the handle 24 is used to facilitate the handling of the battery energy storage cabinet 2. The battery placement plate 27 is fixedly connected to the inside of the installation box 21 by bolts, and the battery is fixed to the battery placement plate 27 by bolts. The mesh plate 25 is fixedly connected to the left side surface of the installation box 21 by bolts, and the first violent fan 26 is fixedly connected to the right side surface of the mesh plate 25 by bolts. A strip-shaped hole 29 is opened on the right side surface of the installation box 21. The strip-shaped hole 29 and the mesh plate 25 can allow air to form convection. When it is necessary to accelerate heat dissipation, the first violent fan 26 can be controlled to work, sucking in the outside air through the strip-shaped hole 29, then passing through the battery to dissipate heat from the battery, and the hot air is discharged through the mesh plate 25. The right wall of the installation box 21 on the left side of the strip-shaped hole 29 is inclined with an aluminum strip 28, and the aluminum strip 28 is installed in a downward inclination. When the air passes through the aluminum strip 28, the aluminum strip 28 cools the air, making the temperature of the air entering the heat dissipation lower and better dissipating heat from the battery. At the same time, because the aluminum strip 28 blocks the inside of the strip-shaped hole 29, when there are impurities in the air, the air passes through the aluminum strip 28 and impacts on the aluminum strip 28, causing the impurities in the air to separate from the air, and the impurities fall downward. The air continues to move in the direction of the first violent fan 26 for heat dissipation. The aluminum strip 28 can block the impurities, reducing the impurities entering the installation box 21, and the air enters the installation box 21 for heat dissipation.

[0037] As Figure 7 and Figure 8As shown, the cooling assembly 3 includes a water tank 31, a heat dissipation aluminum plate 32, a water pipe 33, a heat-conducting copper pipe 34, a branch pipe 35, a heat-conducting plate 36 and a second violent fan 37. The water tank 31 is installed on the top of the uppermost installation box 21, and the bottom of the battery placement plate 27 is provided with a heat dissipation aluminum plate 32. The heat-conducting copper pipe 34 is embedded in the heat dissipation aluminum plate 32. The shape of the part embedded in the inner part of the heat dissipation aluminum plate 32 is S-shaped. The end of the heat-conducting copper pipe 34 passes through the left side of the heat dissipation aluminum plate 32. Two water pipes 33 are provided on the water tank 31. The water pipes 33 are used for water inlet and water outlet. The pipes for water inlet and The inlet of the heat-conducting copper tube 34 is connected, and the pipe for water outlet is connected to the water outlet of the heat-conducting copper tube 34. When the battery is cooled, the heat of the battery is transferred to the heat-conducting copper tube 34 through the heat-dissipating aluminum plate 32. When the water tank 31 is working, the heat-conducting copper tube 34 of the water dissipates heat, so that the heat emitted by the battery can be quickly taken away. The heat-dissipating aluminum plate 32 is composed of an aluminum shell 321, an aluminum cover plate 322, a guide heat sink 323 and an L-shaped connecting pipe 324. The heat-conducting copper tube 34 is installed in the aluminum shell 321, and the aluminum cover plate 322 is covered on the top of the aluminum shell 321 and is sealed and connected to it. At least two groups of guide fins 323 are arranged at the bottom of the cover plate 322. The guide fins 323 are wavy in shape to increase the contact area with the water flow and better take away the heat. An L-shaped connecting pipe 324 is connected between the aluminum shell 321 and the two water pipes 33. When the water tank works to dissipate heat for the battery, water will enter the aluminum shell 321. The water flowing in the aluminum shell 321 can not only dissipate heat for the battery, but also quickly cool down the heat-conducting copper pipe 34 inside and outside, thereby improving the heat dissipation effect. The water pipe 33 between two adjacent heat-conducting copper pipes 34 is connected by a The heat conducting plate 36 is provided on the installation box 21 at the branch pipe 35. The heat conducting plate 36 is staggered with the handle 24. A through hole is vertically opened on the heat conducting plate 36. The branch pipe 35 is stuck in the heat conducting plate 36. Because the branch pipe 35 divides the circulating water into small streams, the contact area between the water flow and the heat conducting plate 36 is increased. When the water flows through the heat conducting plate 36 or flows in the branch pipe 35, the heat in the water flow can be better taken away, so that the water tank can work better. A second violent fan 37 is installed on the water tank 31 above the water pipe 33.

[0038] During use: When heat dissipation is required for the battery energy storage cabinet 2, first control the first violent fan 26 to start working as needed. The first violent fan 26 sucks the outside air into the installation box 21 through the strip-shaped holes 29. When the air passes through the aluminum strip 28, first, the aluminum strip 28 cools the air and blocks the impurities in the air. Then the air enters the installation box 21 to dissipate heat from the batteries in the installation box 21. When it is necessary to further improve the heat dissipation performance, control the water tank 31 to start working. Because of the high thermal conductivity of the heat dissipation aluminum plate 32 and the hollow state inside the heat dissipation aluminum plate 32, the water flow will enter the inside of the heat dissipation aluminum plate 32 through the L-shaped connecting pipe 324. The heat dissipated by the batteries first enters the heat dissipation aluminum plate 32. The water inside the heat dissipation aluminum plate 32 first cools the batteries for the first time. At the same time, the dissipated heat enters the heat conduction copper pipe 34. The water tank 31 works. Because the heat conduction copper pipe 34 is an efficient heat transfer element, it uses the phase change process of water in a closed pipeline to transfer heat, quickly takes away the heat transferred by the heat dissipation aluminum plate 32, and the water in the heat dissipation aluminum plate 32 can also dissipate heat from the heat conduction copper pipe 34, so that the temperature of the heat conduction copper pipe 34 can be quickly cooled down. The two complement each other, and the heat inside the battery energy storage cabinet 2 can be quickly taken away, achieving the effect of efficient cooling. At the same time, when the water tank 31 works, the second violent fan 37 works simultaneously to take away the heat dissipated by the heat conduction plate 36 and the water pipe 33, and cool the water entering and leaving the water tank 31, reducing the water temperature while assisting the water tank 31 in cooling. The vertical through holes on the heat conduction plate 36 enable the wind to penetrate from top to bottom for heat dissipation.

[0039] This device installs multiple battery energy storage cabinets 2 in a stacked manner. When it is necessary to move or one of them has a problem and needs to be disassembled, just unscrew the bolts on the connecting plate 13, and the stacked battery energy storage cabinets 2 can be quickly disassembled, which is convenient and fast.

[0040] It should be understood that this embodiment is only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.
