Description

Technical Field

[0001] The invention belongs to the field of new energy, and in particular relates to an energy storage cabinet. Background Art

[0002] Energy storage cabinets are devices used to store and release electrical energy. They usually consist of a cabinet, a series of battery packs installed in the cabinet, an inverter, and a charge and discharge controller. The battery pack can store electrical energy and release it for power supply when needed. With the rapid development of renewable energy, the demand for energy storage cabinets is also increasing. They are widely used in solar and wind power generation systems to solve the challenges brought by energy volatility. In addition, energy storage cabinets are also used in many fields such as electric vehicle charging stations, microgrids, and industrial fields. When storing electrical energy, energy storage cabinets generate a lot of heat. If this heat cannot be dissipated in time, it will cause the temperature of the energy storage cabinet to rise, which will affect the storage effect and safety. Therefore, the cooling system of the energy storage cabinet is crucial. Traditionally, in order to cool the energy storage cabinet, air conditioning systems and exhaust systems are usually installed in the cabinet. There are also disadvantages: 1. The air conditioner is usually installed on the side of the cabinet, and the cold air circulation is uneven, which cannot evenly cool all battery packs and occupies the battery pack installation space; 2. Condensation water is easily produced in the cabinet and is not easy to discharge, which can easily lead to a short circuit in the cabinet and pose a major safety hazard; 3. The main heat source inverter, charge and discharge controller and battery pack share space, which is not easy to discharge heat, which can easily lead to an increase in the overall temperature of the cabinet; 4. The sealing performance is poor. Summary of the invention

[0026] Reference Figure 1-10 As shown, the energy storage cabinet of the present invention comprises a cabinet body 1 and a cabinet door 2 hinged to the front end of the cabinet body 1. The inner cavity of the cabinet body 1 is provided with a group of storage cabinets 3 for storing batteries, and the storage cabinet 3 can usually store 16-20 battery packs. The back of the cabinet door 2 is provided with an air conditioner installation cavity 4, and the air conditioner for the energy storage cabinet is installed in the air conditioner installation cavity 4. The upper end of the air conditioner installation cavity 4 is provided with an inclined cold air outlet nozzle 5, and the air outlet of the air conditioner for the energy storage cabinet is connected to the cold air outlet nozzle 5. The lower end of the air conditioner installation cavity 4 is provided with an inclined condensate manifold 6. A group of first air intake grille holes 7 are provided at the front of the cabinet door 2 corresponding to the position of the cold air outlet nozzle 5, and the first air intake grille holes 7 are used for air intake of the air conditioner for the energy storage cabinet. The cabinet door 2 is provided with a drain port 8 at the position corresponding to the condensate manifold 6, and condensed water can be discharged through the drain port 8. A drain valve 9 is provided at the bottom of the cabinet door 2, and a drain pipe 10 connected to the air conditioner installation cavity 4 is provided at the upper end of the drain valve 9. The drain pipe 10 is used to connect to the drain port of the air conditioner for the energy storage cabinet and to discharge the condensed water of the air conditioner for the energy storage cabinet. A ceiling-type cold air diverter 11 is provided on the top of the cabinet body 1. The cold air diverter 11 includes a flat air diverter shell 12. The inner cavity of the air diverter shell 12 is divided into an intermediate cold air diverter chamber 14 and side cold air diverter chambers 15 arranged on both sides of the intermediate cold air diverter chamber 14 by a partition 13. An air inlet 16 communicating with the intermediate cold air diverter chamber 14 and the side cold air diverter chamber 15 is provided at the front end of the air diverter shell 12. The middle and both sides of the bottom of the air diverter shell 12 are respectively provided with air outlet grille holes 17 communicating with the intermediate cold air diverter chamber 14 and the side cold air diverter chamber 15. The length of the air outlet grille hole 17 is equal to or close to the length of the storage cabinet 3. The mouth of the cold air outlet nozzle 5 is connected to the air inlet 16 of the ceiling-mounted cold air diverter 11, so that the cold air blown out by the air conditioner of the energy storage cabinet can be blown out evenly through the ceiling-mounted cold air diverter 11, and the cold air can quickly cover the inner cavity of the cabinet body 1.

[0027] Preferably, the bottom of the cabinet 1 is provided with an independently spaced power controller installation cavity 18 for installing the main heat source inverter and the charge and discharge controller. The bottom of the back of the cabinet door 2 is provided with an air intake and exhaust fan 19 connected to the front end of the power controller installation cavity 18, and the bottom of the back of the cabinet 1 is provided with an air outlet and exhaust fan 20 connected to the rear end of the power controller installation cavity 18. Through the air intake and exhaust fan 19 and the air outlet and exhaust fan 2, the power controller installation cavity 18 can form air convection. A group of cold air inlet holes 21 connected to the inner cavity of the cabinet 1 are provided above the power controller installation cavity 18. Through the cold air inlet holes 21, the cold air in the inner cavity of the cabinet 1 can be introduced into the power controller installation cavity 18 to supplement the cooling of the equipment in the power controller installation cavity 18. A slidable adjustment plate 34 is provided on the cold air inlet hole 21 of the power controller installation cavity 18. The opening of the cold air inlet hole 21 is adjusted by sliding the adjustment plate 34, thereby adjusting the amount of cold air entering the power controller installation cavity 18. A temperature sensor 38 is usually installed in the power controller installation cavity 18. When the temperature sensor 38 detects that the temperature in the power controller installation cavity 18 is too high, an alarm is issued to prompt the user to open the adjustment plate 34 for cooling; when the temperature in the power controller installation cavity 18 is normal, the adjustment plate 34 can be closed to achieve energy saving.

[0028] Preferably, the partition 13 is composed of a first partition 22 arranged longitudinally and a second partition 23 arranged obliquely. The second partition 23 divides the side cold air diversion chamber 15 into a triangular structure that is wide in the front and narrow in the back, so as to quickly discharge the cold air.

[0029] Preferably, a group of supporting rollers 24 are provided at the bottom of the cabinet door 2, and the supporting rollers 24 are used to roll with the bottom of the cabinet body 1. Since the cabinet door 2 is heavy after the energy storage cabinet air conditioner is installed, the support rollers 24 make it easier to open or close the cabinet door 2.

[0030] Preferably, the front end of the cold air outlet nozzle 5 is provided with a closed sealing ring 26 through a flange 25, which is sealed with the air inlet 16 of the wind diverter shell 12. The cross-section of the closed sealing ring 26 includes a U-shaped clamping portion 27 and a closed semicircular sealing portion 28 integrally formed at the front end of the U-shaped clamping portion 27. The inner walls on both sides of the U-shaped clamping portion 27 are provided with inclined claws 29, and the two ends of the closed semicircular sealing portion 28 are provided with eight-shaped sealing ribs 30. The advantages of using the above-mentioned closed sealing ring 26 are: 1. The sealing ring adopts a U-shaped clamping portion 27 to be quickly connected to the flange 25 of the cold air outlet nozzle 5, and is clamped by the inclined clamping claw 29. When the closed sealing ring 26 is collided, it will move inward to play a role of stopping retreat and thus prevent it from falling off; 2. The sealing ring adopts a closed semicircular sealing portion 28 and an eight-shaped sealing rib 30 to seal with the air inlet 16. When the cabinet door 2 is closed, it not only has a good sealing effect, but also has a buffering effect.

[0031] Preferably, the claws 29 include three short claws 31 disposed on the front inner wall of the U-shaped clamping portion 27 and one long claw 32 disposed on the rear inner wall of the U-shaped clamping portion 27. When the closed sealing ring 26 is collided, the three short claws 31 can be supported on the flange 25 more stably and more evenly to improve the reliability of the clamping.

[0032] Preferably, spoilers 33 for isolating the air outlet grille holes 17 are provided on both sides of the bottom of the wind splitter housing 12. The spoilers 33 enable the cold air to flow vertically downward quickly to improve the cooling effect and speed.

[0033] Preferably, the storage cabinet 3 is composed of a set of L-shaped rails 35 arranged opposite to each other, so that the battery pack can be disassembled and assembled by pulling out, making the installation more convenient. The two ends of the upper wall of the L-shaped rail 35 are integrally formed with arc-shaped positioning springs 36 protruding inward. After the battery pack is installed, the arc-shaped positioning springs 36 abut against the two sides of the battery pack to fix the battery pack.

[0034] Preferably, a heat-insulating layer 37 is provided inside the cabinet body 1 and the cabinet door 2, and the heat-insulating layer 37 is usually a foam board, so as to stabilize the temperature inside the cabinet body 1, thereby achieving the purpose of energy saving and emission reduction.
