Abstract
Description
Technical Field
[0001] This utility model relates to the field of power facility technology, and in particular to a liquid-cooled outdoor energy storage integrated cabinet. Background Technology
[0002] In response to the challenges posed by fluctuating electricity demand and insufficient power stability in the power market, outdoor integrated energy storage cabinets have seen significant market demand for effectively addressing power consumption and peak shaving / valley filling issues in industrial parks and remote areas. These integrated cabinets combine DC and AC sides, including energy storage battery packs, liquid cooling systems, fire suppression systems, battery management systems, energy management systems, and energy storage inverters. Energy storage batteries require relatively constant temperature and humidity conditions to ensure optimal cycle life, hence the need for a liquid cooling system. During operation, the integrated cabinet must consider insulation and energy conservation. Due to environmental temperature differences, condensation may occur in the liquid cooling system, necessitating a sealed design for the battery compartment. Furthermore, since energy storage cabinets are typically located outdoors, they must withstand various natural phenomena to ensure normal operation. Therefore, the design and manufacturing processes of outdoor cabinets require careful consideration, demanding excellent corrosion resistance and impact resistance. Therefore, most of the energy storage integrated cabinets commonly found on the market adopt a fully sealed design. This design greatly reduces the heat dissipation conditions inside the cabinet. If the temperature inside the cabinet is too high, it will lead to increased energy consumption and may also cause device malfunction, aging, fire in the battery compartment, and other dangers, posing safety risks.
[0003] To address the aforementioned technical issues, Chinese utility model patent No. 202320829461.4 discloses an integrated outdoor energy storage cabinet. Air inlet and outlet windows are provided at corresponding positions in the first and second compartments used for equipping AC-side electrical equipment. These windows are located on opposite sides of the cabinet. However, when multiple such cabinets need to be installed side-by-side to increase capacity, the cabinet doors open forward, requiring multiple cabinets to be arranged horizontally. After installation, the function of the air inlet and outlet windows on the sides of the cabinet is inevitably affected, leading to poor overall heat dissipation and consequently affecting the normal operation of the internal equipment. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide a liquid-cooled outdoor energy storage integrated cabinet with a simple structure and stable heat dissipation performance even after multiple cabinets are installed side by side.
[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:
[0006] A liquid-cooled outdoor energy storage cabinet includes a cabinet body with a front-opening chamber. The front opening of the cabinet body has a door that can be opened and closed to seal it. The chamber contains a first compartment for installing AC-side electrical equipment. An air inlet area is located on the door corresponding to the first compartment. An air outlet area is located at the rear of the cabinet corresponding to the first compartment. The air inlet area has a first rainproof mechanism to prevent external rainwater from entering the cabinet body, and the air outlet area has a second rainproof mechanism to prevent external rainwater from entering the cabinet body.
[0007] The air intake area is provided with dense heat dissipation air intake holes. The first rainproof mechanism includes a first louver, which includes a first window frame and a first rainproof louver disposed within the first window frame. The first window frame is disposed in the air intake area and installed in the cabinet. All the air intake heat dissipation holes are located within the first window frame. The blades of the first rainproof louver are inclined upward from front to back.
[0008] A dustproof net is installed behind the first rainproof louver.
[0009] The upper or side portion of the first window frame is provided with an insertion port for inserting and installing the dustproof net. After the dustproof net is inserted into the insertion port, it is positioned behind the first rainproof louver.
[0010] The first window frame, which does not have the aforementioned insertion port, has sliding grooves on its two opposite inner wall surfaces for guiding the dustproof net to slide into and install.
[0011] The air outlet area is provided with dense air outlet holes. The second rainproof mechanism includes a second louver, which includes a second window frame and a second rainproof louver disposed within the second window frame. The second window frame is disposed in the air outlet area and installed in the cabinet. All air outlet holes are located within the second window frame. The blades of the second rainproof louver are inclined downwards from front to back.
[0012] A cooling fan is installed in the first cabin at the location corresponding to the air outlet area.
[0013] The cooling fan is an axial flow fan.
[0014] The cabinet is equipped with an explosion-proof valve.
[0015] The chamber also includes a second compartment for equipping a DC-side energy storage battery pack and a third compartment for equipping a liquid cooler. The third compartment, the second compartment, and the first compartment are arranged sequentially from top to bottom. The cabinet door has multiple dense air inlets corresponding to the position of the third compartment, and the back of the cabinet has multiple dense air exhaustlets corresponding to the position of the third compartment. The bottom plate of the third compartment is inclined.
[0016] The cabinet door is equipped with ventilation louvers.
[0017] The front end of the first rain-proof louver is tilted upwards to form a front baffle, which is tilted backwards from top to bottom. The rear end of the first rain-proof louver is bent downwards to form a guide section, which is tilted backwards from top to bottom. The end of the guide section is bent to form a rear baffle, which is tilted forwards from top to bottom.
[0018] Compared with the prior art, the advantages of this utility model are as follows: The first compartment is used to equip AC side electrical equipment. An air inlet area and an air outlet area are set on the cabinet corresponding to the position of the compartment, and the air inlet area and the air outlet area are arranged front and back to achieve front and rear air intake and exhaust heat dissipation. When multiple cabinets are installed side by side, it will not affect the heat dissipation of a single cabinet. Whether installed individually or in multiple cabinets, heat dissipation can be guaranteed, thereby reducing energy consumption and avoiding risks such as device failure, aging, and battery compartment fire caused by excessive temperature, thus improving the safety of use. In addition, rainproof mechanisms are set in the air inlet area and the air outlet area respectively, which can effectively prevent external rainwater from entering without affecting ventilation and heat dissipation, further ensuring the safety of use.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0029] As shown in the figure, a liquid-cooled outdoor energy storage integrated cabinet includes a cabinet body 1. The cabinet body 1 has a chamber 10 with a front opening. A cabinet door 2 is provided on the front opening of the cabinet body 1, which can be opened and closed to close the front opening of the cabinet body 1. A first compartment 101 for installing AC side electrical equipment is provided in the chamber. An air inlet area 3 is provided on the cabinet door 2 at the position corresponding to the first compartment 101. An air outlet area 4 is provided at the rear of the cabinet body 1 at the position corresponding to the first compartment 101. The air inlet area 3 is provided with a first rainproof mechanism to prevent external rainwater from entering the cabinet body 1. The air outlet area 4 is provided with a second rainproof mechanism to prevent external rainwater from entering the cabinet body 1.
[0030] In this specific embodiment, the air intake area 3 is provided with densely packed heat dissipation air intake holes 301. The first rainproof mechanism includes a first louver 302, which includes a first window frame 3021 and first rainproof louvers 30 disposed within the first window frame 3021. The first window frame 3021 is located in the air intake area 3 and installed inside the cabinet 1. All the air intake and heat dissipation holes 301 are located within the first window frame 3021. The blades of the first rainproof louvers 31 are inclined upwards from front to back. The above-mentioned rainproof mechanism has a simple structure and can effectively prevent external rainwater from entering the cabinet without affecting ventilation and heat dissipation.
[0031] In this specific embodiment, a dustproof net 304 is provided behind the first rainproof louver 30. The dustproof net 304 can effectively prevent external dust from entering the cabinet 1 through the air inlet window.
[0032] In this specific embodiment, the upper or side portion of the first window frame 3021 is provided with an insertion port 3023 for inserting and installing a dustproof net 304. After being inserted into the insertion port 3023, the dustproof net 304 is positioned behind the first rainproof louver 30. Since the dustproof net 304 is a vulnerable component, a large amount of dust will adhere to it after a period of operation, thereby affecting the ventilation and heat dissipation of the equipment. The above design allows for easy replacement of the dustproof net 304, ensuring the stability of heat dissipation.
[0033] In this specific embodiment, the two opposing inner wall surfaces of the first window frame 3021, which does not have an insertion port 3023, are respectively provided with sliding grooves 3024 for guiding the dustproof net 304 to slide into and install. The sliding grooves 3024 serve to guide and position the installation of the dustproof net 304.
[0034] In this specific embodiment, the air outlet area 4 is provided with densely packed air outlet holes 401. The second rainproof mechanism includes a second louver 402, which includes a second window frame 4021 and second rainproof louvers 40 disposed within the second window frame 4021. The second window frame 4021 is located in the air outlet area 4 and installed inside the cabinet 1. All air outlet holes 401 are located within the second window frame 4021. The blades of the second rainproof louvers 40 are inclined downwards from front to back. The above-mentioned rainproof mechanism has a simple structure and can effectively prevent external rainwater from entering the cabinet without affecting ventilation and heat dissipation.
[0035] In this specific embodiment, a cooling fan 5 is installed in the first compartment 101 at the location corresponding to the air outlet area 4. The cooling fan 5 works in conjunction with the cooling fan to achieve more efficient heat dissipation.
[0036] In this specific embodiment, the cooling fan 5 is an axial fan.
[0037] In this specific embodiment, an explosion-proof valve 6 is installed on the cabinet 1. Since the battery compartment is a closed space, it affects the rapid depressurization of the cabinet 1. The explosion-proof valve 6 can quickly release high-pressure gas to the outside of the cabinet 1, solving the problem of rapid depressurization of the cabinet 1 and ensuring safe and stable use.
[0038] In this specific embodiment, the chamber also includes a second compartment 102 for equipping a DC-side energy storage battery pack and a third compartment 103 for equipping a liquid cooler. The third compartment 103, the second compartment 102, and the first compartment 101 are arranged sequentially from top to bottom. Multiple densely packed air inlets 21 are provided on the cabinet door 2 corresponding to the position of the third compartment 103, and multiple densely packed exhaust vents 22 are provided on the back of the cabinet body 1 corresponding to the position of the third compartment 103. The bottom plate 1031 of the third compartment 103 is inclined. In extreme weather conditions, rainwater may enter the third compartment 103 through the air inlets 21 and exhaust vents 22. Additionally, the liquid cooler may leak liquid. Rainwater and leaked liquid can be collected by the inclined bottom plate 1031 and drained outwards at the front and rear of the cabinet body 1, thereby preventing damage to the internal electrical components.
[0039] In this specific embodiment, the cabinet door 2 is provided with ventilation louvers 22. Toxic gases generated by battery leakage under extreme conditions can be discharged to the outside through this structure.
[0040] In this specific embodiment, the front end of the first rain-blocking louver 30 is angled upwards to form a front baffle 31, which is tilted backwards from top to bottom. The rear end of the first rain-blocking louver 30 is angled downwards to form a guide portion 32, which is tilted backwards from top to bottom. The end of the guide portion 32 is bent to form a rear baffle 33, which is tilted forwards from top to bottom. This provides better rain protection.
[0041] In this specific embodiment, the second compartment 102 is provided with multiple mounting brackets for supporting the battery pack, each mounting bracket consisting of two opposing mounting rails 1021. The mounting rails 1021 enable the plug-in installation and removal of the battery pack; when the battery pack needs to be installed or removed, it is pushed in or pulled out by the mounting rails 1021.
[0042] In this specific embodiment, a lifting component 12 is provided on the top of the cabinet 1 to facilitate lifting, loading, and transportation.
[0043] In this specific embodiment, a monitoring camera 13 is installed on the exterior of the cabinet 1. The camera can effectively monitor the surrounding environment when the system is running.
[0044] In this specific embodiment, the exterior of the second compartment 102 is wrapped with insulating rock wool 1022. This serves to insulate the battery compartment located within the second compartment 102, thereby effectively ensuring the cycle life of the battery.
