Description

Technical Field

[0001] The utility model relates to the technical field of energy storage, and in particular to a vertical direct-cooling air-conditioning unit and an energy storage cabinet equipped with the vertical direct-cooling air-conditioning unit. Background Art

[0002] Outdoor energy storage cabinets have problems with poor heat dissipation due to the large number of batteries installed and light radiation. Batteries in high temperature environments will reduce their service life, fail to charge normally, and even explode; low temperatures in winter will cause the battery to lose power, fail to charge and discharge normally, and reduce its service life.

[0003] There are two common types of energy storage air conditioning products on the market: air cooling and liquid cooling. Liquid cooling has gradually become the main means of energy storage temperature control. Most liquid cooling temperature control products are currently large in size and heavy in weight, making them difficult to repair, replace and move. The large size leads to high costs and large floor space, which squeezes the space for the batteries in the energy storage cabinet. At the same time, the liquid cooling energy storage temperature control products on the market have high energy consumption and low energy efficiency. While dissipating heat for batteries and PCS (energy storage converter), they also consume a lot of electricity, which is not in line with the current development trend of low-carbon energy saving.

[0004] With the development of energy storage battery technology, high-capacity battery cells are gradually used, and the installed density of energy storage systems is gradually increasing. The requirements for the capabilities of temperature control products are increasing. The shortcomings of liquid-cooled temperature control products, such as slow heating and cooling rates, poor temperature uniformity of battery cells, low energy conversion efficiency, and high system costs, are becoming increasingly apparent.

[0005] In order to solve the above problems, improve the temperature adjustment rate of energy storage cabinets, the temperature uniformity of battery cells and the energy conversion efficiency, and reduce system costs, there are more and more studies on the use of refrigerant direct cooling systems for temperature control of energy storage cabinets, and direct cooling energy storage cabinets have emerged.

[0006] The direct cooling energy storage cabinet includes a cabinet body, a direct cooling air-conditioning unit, a direct cooling plate and a power supply. The internal space of the cabinet body is divided into a battery compartment, an air-conditioning compartment and a power supply compartment. The direct cooling air-conditioning unit is arranged in the air-conditioning compartment, the power supply is arranged in the power supply compartment, and the energy storage battery is placed in the battery compartment with upper and lower intervals.

[0007] The air conditioning compartment is through-connected front to back, the return air inlet of the direct cooling air conditioning unit faces the front through-connection of the air conditioning compartment, and the air outlet of the direct cooling air conditioning unit faces the rear through-connection of the air conditioning compartment, so as to ventilate and dissipate heat for the direct cooling air conditioning unit during cooling.

[0008] The direct cooling plate is installed in the battery compartment and connected to the direct cooling air-conditioning unit to form a refrigerant circulation loop. The direct cooling plate corresponds to the battery one by one to exchange heat with the battery and control the temperature of the battery.

[0009] Since most of the direct cooling air conditioning units currently applied to direct cooling energy storage cabinets are of integral structure design, forming a unit module, which is internally provided with a condenser, a regenerator, a compressor, a fan, an electric control box, a refrigerant pipeline, etc. Among them, the electric control box is installed at the top, that is, installed on the inner wall of the top plate of the unit housing, while the compressor and the liquid storage tank are installed in the unit housing near the air return opening, and the condenser is installed in the unit housing near the air outlet. Then, when it is necessary to disassemble and repair the electric control box, the top plate of the unit housing needs to be removed for maintenance from above the unit. When it is necessary to disassemble and repair the compressor or the liquid storage tank or the condenser, the side plate of the unit housing needs to be removed for maintenance from the side of the unit, making disassembly and repair inconvenient, and the internal space of the housing is not reasonably utilized for the layout of each component, resulting in a large space occupied by the unit.

[0060] Referring to Figure 1 and Figure 2 , in some embodiments of the present application, an energy storage cabinet is proposed, which includes a cabinet body 100 and a vertical direct cooling air conditioner unit 200, and of course, a direct cooling plate is also included.

[0061] Among them, the cabinet body 100 is usually a rectangular parallelepiped cabinet body 100, and its internal space is at least divided into an air conditioner compartment 110 and a battery compartment. The air conditioner compartment 110 and the battery compartment are independent of each other, and the air conditioner compartment 110 is arranged on the side of the battery compartment. The cabinet body 100 has an opening on the front side and is configured with a cabinet door 120 for opening and closing the energy storage cabinet.

[0062] The battery compartment is at least used for accommodating batteries. The batteries are specifically energy storage batteries and are arranged in the battery compartment in the form of battery PACKs encapsulated by battery clusters.

[0063] The air-conditioning compartment 110 is used to install the vertical direct-cooling air-conditioning unit 200. The air-conditioning compartment 110 is penetrated from front to back to facilitate the return air and air supply of the vertical direct-cooling air-conditioning unit 200.

[0064] The vertical direct-cooling air-conditioning unit 200 is installed in the air-conditioning compartment 110 and is used to adjust the temperature of the energy storage cabinet, manage the constant temperature of the energy storage cabinet, mainly used to adjust the temperature of the batteries in the battery compartment, so that the batteries can work within an ideal temperature range, avoiding too high or too low battery temperature.

[0065] Refer to Figures 3 to 9 , the outer contour of the vertical direct-cooling air-conditioning unit 200 of the energy storage cabinet is in the shape of a flat cuboid with a relatively small width dimension, and is placed in the air-conditioning compartment 110 in a vertical posture, including a housing 210 and a direct-cooling temperature control module.

[0066] The outer contour of the housing 210 is in the shape of a flat cuboid with a relatively small width dimension, including a top plate 216, a bottom plate 217, two first side plates 218 opposite to each other in the front and back, and two second side plates 219 opposite to each other on the left and right. An air return grille is provided on the front first side plate 218 to form the air return opening 211, and an air supply grille is provided on the rear first side plate 218 to form the air supply opening 212. The air return opening 211 is facing the front through opening of the air-conditioning compartment 110, and the air supply opening 212 is facing the rear through opening of the air-conditioning compartment 110, realizing front air return and rear air supply.

[0067] The inner cavity of the housing 210 includes a first installation area 213, a second installation area 214, and a third installation area 215 that are sequentially arranged and communicated along the front-back direction of the housing 210. The first installation area 213 is communicated with the air return opening 211, the third installation area 215 is communicated with the air supply opening 212, and the second installation area 214 is located between the first installation area 213 and the third installation area 215.

[0068] The direct-cooling temperature control module uses the phase change of the refrigerant to exchange heat with the battery to achieve battery temperature adjustment. Its structural components and temperature control principle are the same as those of the prior art, and will not be elaborated here. Among the structural components of the direct-cooling temperature control module, at least include a compressor 220, a condenser 230, a regenerator 240, a liquid storage tank 250, a fan 260, and an electric control box 270, etc.

[0069] The direct-cooling plate is arranged in the battery compartment and is used to exchange heat with the battery. A refrigerant flow channel is formed inside the direct-cooling plate. The compressor 220, the condenser 230, the regenerator 240, and the direct-cooling plate are sequentially connected by pipelines to form a refrigerant circulation loop. Electronic expansion valves are arranged at both the inlet and outlet of the direct-cooling plate, and the refrigerant in the refrigerant circulation loop flows through the direct-cooling plate to exchange heat with the battery.

[0070] The electric control box 270 is arranged in the first installation area 213.

[0071] The regenerator 240 is also located in the first installation area 213.

[0072] The compressor 220, the condenser 230 and the liquid storage tank 250 are arranged in the second installation area 214. The condenser 230 is arranged upright and inclined relative to the second side plate 219, that is, the condenser 230 is neither parallel to the second side plate 219 nor vertically to the second side plate 219. The compressor 220 and the liquid storage tank 250 are located on the same side of the condenser 230.

[0073] The fan 260 is disposed in the third installation area 215, and the axis of the fan 260 extends horizontally forward and backward.

[0074] The electrical control box 270, the compressor 220 and the liquid storage tank 250 are all close to the same second side plate 219, for example, the electrical control box 270, the compressor 220 and the liquid storage tank 250 are all close to the second side plate 219 on the right side, or the electrical control box 270, the compressor 220 and the liquid storage tank 250 are all close to the second side plate 219 on the left side.

[0075] In some embodiments of the present application, the vertical direct-cooling air-conditioning unit 200 divides the inner cavity of the unit shell 210 into partitions to reasonably install and arrange the various structural components of the air-conditioning unit to make the internal structure of the unit compact; and the condenser 230 with a larger height and volume is vertically and tilted to form a direct-cooling vertical air-conditioning unit, which fully utilizes the height space of the second installation area 214 for installation and reduces the horizontal and vertical space occupancy; the compressor 220 and the liquid storage tank 250 are located on the same side of the condenser 230 to fully utilize the side space of the condenser 230 and reduce the wiring distance between the compressor 220 and the condenser 230.

[0076] The electric control box 270, the compressor 220 and the liquid storage tank 250 are all close to a second side plate 219 on the same side, for example, they are all close to the second side plate 219 on the left side or they are all close to the second side plate 219 on the right side, so that it is convenient to disassemble, maintain or repair the electric control box 270, the compressor 220 or the liquid storage tank 250 from the same side of the whole machine. The vertical direct cooling air conditioning unit 200 has a compact structure, which is conducive to reducing the volume of the entire unit, so that the battery installation space in the energy storage cabinet in some embodiments of the present application is relatively increased, which can increase the battery capacity of the energy storage cabinet.

[0077] In some embodiments of the present application, the same side of the condenser 230 refers to the side of the condenser 230 that is away from the fan 260. Figure 5 and Figure 6As shown, the right side of the condenser 230 faces away from the fan 260, and this side is referred to as the windward side of the condenser 230. The left side of the condenser 230 faces the fan 260, and this side is referred to as the air outlet side of the condenser 230. The electric control box 270, the compressor 220, and the liquid storage tank 250 are all close to the second side plate 219 on the right side. When the fan 260 operates, the heat dissipated by the condenser 230 is discharged through the air outlet 212, and the air with a lower outside temperature returns through the air return port 211. Then, the electric control box 270, the compressor 220, and the liquid storage tank 250 are located away from the air outlet side of the condenser 230 to avoid blocking the heat dissipation air flow of the condenser 230 and minimize the impact on the heat dissipation of the condenser 230 as much as possible.

[0078] In some embodiments of the present application, the front side of the condenser 230 is close to the second side plate 219 on one side, and a front windshield portion is provided between the front side of the condenser 230 and the second side plate 219.

[0079] The rear side of the condenser 230 is close to the second side plate 219 on the other side, and a rear windshield portion is provided between the rear side of the condenser 230 and the second side plate 219.

[0080] The top and bottom of the condenser 230 respectively abut against the top plate 216 and the bottom plate 217.

[0081] Taking Figure 5 and Figure 6 the perspective shown, the front side of the condenser 230 is close to the second side plate 219 on the left side, the rear side of the condenser 230 is close to the second side plate 219 on the right side, and a vertically arranged front windshield plate 280 is connected between the vertical side of the front side of the condenser 230 and the second side plate 219 on the left side to form the front windshield portion; similarly, a vertically arranged rear windshield plate (not shown in the figure due to the perspective) is connected between the vertical side of the rear side of the condenser 230 and the second side plate 219 on the right side to form the rear windshield portion.

[0082] The front windshield plate 280 is specifically a vertically strip-shaped plate with an L-shaped cross-section. One side of it is attached to the second side plate 219 on the left side and is fixedly connected at intervals along the vertical direction through a plurality of screws, and the other side is attached to the housing 210 of the condenser 230 and is fixedly connected at intervals along the vertical direction through a plurality of screws. The rear windshield plate is arranged in the same way.

[0083] By providing the front windshield plate 280 and the rear windshield plate, with the top and bottom of the condenser 230 respectively abutting against the top plate 216 and the bottom plate 217, it is possible to make the condenser 230 as closed and seamless as possible between the second side plate 219 on the left side and the second side plate 219 on the right side, and between the condenser 230 and the top plate 216 and the bottom plate 217, isolating the air inlet side and the air outlet side of the condenser 230, avoiding heat exchange between the air inlet side and the air outlet side of the condenser 230, and helping to improve the heat exchange effect.

[0084] In some embodiments of the present application, to enhance the structural strength of the housing 210, the vertical direct-cooling air conditioner unit 200 further includes a support frame located in the inner cavity of the housing 210. The support frame is disposed in conformity with the housing 210 and specifically includes a plurality of transverse top supports 290, a plurality of transverse middle supports 2100, and a plurality of vertical supports 2110.

Specifically, it can be fixed by a plurality of screws spaced along the extending direction of the vertical support 2110.

[0086] Among the plurality of transverse top supports 290, a part of which is disposed in conformity with the second side plate 219 on the left side, and another part of which is disposed in conformity with the second side plate 219 on the right side, and is integrally fixed to the corresponding second side plate 219. Specifically, it can be fixed by a plurality of screws spaced along the extending direction of the transverse top support 290; the transverse top support 290 is horizontally arranged and extends front and back, and it is also integrally fixed in conformity with the top plate 216 of the housing 210. The transverse top support 290 on the left side is in conformity with the left side edge of the top plate 216, and the transverse top support 290 on the right side is in conformity with the right side edge of the top plate 216.

[0087] Among the plurality of transverse middle supports 2100, a part of which is disposed in conformity with the second side plate 219 on the left side, and another part of which is disposed in conformity with the second side plate 219 on the right side, and is integrally fixed to the corresponding second side plate 219. Specifically, it can be fixed by a plurality of screws spaced along the extending direction of the transverse middle support 2100. The transverse middle support 2100 is horizontally arranged and extends front and back. It is located below the transverse top support 290 and has a length shorter than that of the transverse top support 290.

[0088] The top end of the vertical support 2110 is integrally fixed to the transverse top support 290, and the bottom end is integrally fixed to the bottom plate 217. The front end of the transverse top support 290 is integrally fixed to the first side plate 218 at the front. The transverse middle support 2100 is located at a certain distance above the bottom plate 217. Its front end is integrally fixed to the first side plate 218 at the front, and the rear end is integrally fixed to the vertical support 2110.

[0089] For example, as Figures 7 to 9 shown, one vertical support 2110 is provided on each of the left and right sides, approximately located at the middle position in the front-back direction; one transverse top support 290 is provided on each of the left and right sides, and one transverse middle support 2100 is provided on each of the left and right sides.

[0090] Each component of the support frame can specifically be a metal plate or a pipe fitting. Through the above connection structure, the support frame can be connected to the housing 210 of the unit to form a stable outer housing member, which supports the entire housing 210 from the inside of the housing 210 to ensure the structural strength of the entire outer housing member. Then, the housing 210 can be made of sheet metal. The support frame can also be used as a mounting rack for some internal components to facilitate the installation of some internal components.

[0091] For the installation of the electric control box 270, as Figures 5 to 9 shown, the electric control box 270 is erected, including an electric control box body 271 and a detachable electric control box cover 272.

The opening of the electric control box body 271 faces horizontally outward, and its top and bottom are respectively fixedly connected to the horizontal top support member 290 and the horizontal middle support member 2100 on the same side.

[0092] Taking Figures 5 to 9 the electric control box 270, the compressor 220, and the liquid storage tank 250 shown as an example, all are arranged on the right side, that is, close to the second side plate 219 on the right side. The opening of the electric control box body 271 faces horizontally to the right. The top and bottom of the electric control box body 271 are respectively fixedly connected to the horizontal top support member 290 and the horizontal middle support member 2100 on the right side. The electric control box cover 272 is located outside the electric control box body 271 and can be specifically detachably connected to the opening side of the electric control box body 271 through a plurality of screws.

[0093] When it is necessary to maintain or repair the internal devices of the electric control box 270, the second side plate 219 on its side can be disassembled, and then the electric control box cover 272 can be disassembled. The internal devices of the electric control box 270 can be maintained or repaired from one side of the unit, and the compressor 220 or the liquid storage tank 250 can also be disassembled, installed, maintained, or repaired from this side at the same time.

[0094] In some embodiments of the present application, as Figure 8 and Figure 9 shown, an upwardly folded upper folded edge 273 is formed on the upper edge of the opening of the electric control box body 271, and a downwardly folded lower folded edge 274 is formed on the lower edge of the opening of the electric control box body 271. The upper folded edge 273 is fixedly connected in fit with the horizontal top support member 290, and the lower folded edge 274 is fixedly connected in fit with the horizontal middle support member 2100. Specifically, it can be detachably connected through a plurality of screws to facilitate installation.

[0095] Correspondingly, the two vertical sides of the electric control box cover 272 and the corresponding vertical sides of the electric control box body 271 are detachably connected by screws to facilitate disassembly and assembly.

[0096] In some embodiments of the present application, the second installation area 214 and the third installation area 215 are separated by a first partition 2120 vertically arranged, and a through portion 2121 aligned and connected to the air suction end of the fan 260 is formed on the first partition 2120. The top end of the first partition 2120 is integrally fixed to the rear end of the transverse top support 290, and the bottom end is integrally fixed to the bottom plate 217 of the unit housing 210.

[0097] A plurality of fans 260 are arranged up and down along the height direction of the housing 210 in the third installation area 215. Adjacent fans 260 are separated by a second partition 2130. The front side edge of the second partition 2130 is attached and connected to the first partition 2120, and the left and right side edges of the second partition 2130 are respectively attached and connected to the second side plates 219 on both sides.

[0098] Then, the second partition 2130 is designed to separate between the multiple fans 260, which can avoid the interference of the air fields of the fans 260 and effectively improve the air output.

[0099] A fan support 2140 is provided in the third installation area 215. The fan support 2140 is vertically arranged. Its front side is fixedly connected to the first partition 2120, and the bottom end is fixedly arranged on the bottom plate 217. The air exhaust end of the fan 260 is fixedly connected to the fan support 2140, and the rear side edge of the second partition 2130 is fixedly connected to the fan support 2140. Then, the fan support 2140 and the first partition 2120 form a stable installation support for the fan 260, ensuring the supporting ability for the fan 260, so that the fan 260 will not shake by itself during operation and ensuring reliable operation.

[0100] The fan support 2140 has a frame-like structure. Its top end has a connecting portion 2141 bent and extended forward (i.e., the side where the first partition 2120 is located). The front end of the connecting portion 2141 is fixedly connected to the first partition 2120 by screws, and a sheet metal reinforcement is welded between the rear end of the connecting portion 2141 and the fan support 2140 to improve the structural strength of the entire fan support 2140.

[0101] As Figure 7 shown, the number of fans 260 is two. Correspondingly, one second partition 2130 is provided. The number of fans 260 depends on the height of the unit. The greater the height of the unit, the more the number of fans 260; the smaller the height of the unit, the fewer the number of fans 260.

[0102] In some embodiments of the present application, referring to Figure 10 , the bottom plate 217 of the unit housing 210 is in the shape of a rectangular plate with an upward opening. A drain nozzle 2171 is provided on one of the side walls of the bottom plate 217 for externally connecting a drain pipe to collect the accumulated water inside the unit and drain the accumulated water outside the unit.

[0103] On the bottom wall of the base plate 217, there are spaced apart along the front-to-back direction an upwardly protruding condenser mounting position 2172 and a fan mounting position 2713, and an upwardly protruding compressor mounting position 2174, and the compressor mounting position 2174 is located on one side of the condenser mounting position 2172. The condenser mounting position 2172, the fan mounting position 2713, and the compressor mounting position 2174 all have a horizontal mounting top plate, corresponding to the installation of the condenser 230, the fan 260, and the compressor 220, respectively.

[0104] The height of the horizontally installed top plate is higher than the height of the drain nozzle 2171 to prevent the condenser 230, the fan 260, and the compressor 220 from contacting the accumulated water in the bottom plate 217 as much as possible.

[0105] In some embodiments of the present application, the drain nozzle 2171 is disposed on the front side wall of the bottom plate 217 to facilitate opening the energy storage cabinet door 120 and connecting an external drain pipe at the cabinet opening.

[0106] For the installation of the liquid storage tank 250, Figures 6 to 8 As shown, a horizontal mounting beam 2150 is connected between the vertical support member 2110 on the right and the horizontal middle support member 2100 on the left. The mounting beam 2150 is located at the junction of the first mounting area 213 and the second mounting area 214. The liquid storage tank 250 is clamped on the mounting beam 2150 through a hoop and is located in the second mounting area 214 to make full use of the space in the middle of the height direction in the second mounting area 214 for installation.
