[0001] This utility model relates to the field of new energy, and in particular to energy storage cabinets, specifically a fireproof door that can provide cyclic cooling for the energy storage cabinet. Background Technology
[0002] With the transformation of the global energy structure and the large-scale development and utilization of renewable energy, energy storage technology has developed rapidly as a key means to solve the imbalance between energy supply and demand and improve energy efficiency. As the core equipment of energy storage systems, energy storage cabinets are widely used in many fields such as power systems, communication base stations, data centers, and industrial parks to store electrical energy and release it when needed, so as to ensure the stability, reliability and flexibility of power supply.
[0003] The energy storage cabinet contains chemical battery packs for energy storage. Due to the physical and chemical properties of the batteries, the battery packs are prone to high temperatures, which can lead to spontaneous combustion or fire spillage, causing major accidents. Therefore, the energy storage cabinet door needs to be designed with fire resistance to prevent fire spillage, while also allowing for circulating cooling to cool the battery packs. The original energy storage cabinet door uses a single-sided steel plate design, which cannot meet the requirement of preventing fire spillage. Therefore, we need to propose a fireproof door that can provide circulating cooling for the energy storage cabinet. Utility Model Content
[0004] The purpose of this invention is to provide a fireproof door that can provide cyclic cooling for the energy storage cabinet. By setting two independent fireproof door panels, the larger fireproof door panel is installed on the battery cavity to prevent fire from spilling out; the smaller fireproof door panel has ventilation mesh holes, and the cyclic cooling component provides cyclic cooling for the battery pack in the battery cavity, thereby solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A fireproof door that provides circulating cooling for an energy storage cabinet includes an energy storage cabinet, a fireproof partition, a large fireproof door leaf, a small fireproof door leaf, hinges, a circulating cooling component, and an exhaust component. The fireproof partition is fixedly installed inside the energy storage cabinet. The energy storage cabinet is divided into a battery cavity and a cooling cavity. The battery cavity is used to install battery packs. The large fireproof door leaf is hinged to one side of the battery cavity, and the small fireproof door leaf is hinged to one side of the cooling cavity. The circulating cooling component is installed inside the cooling chamber to cool the inside of the battery chamber, while the exhaust component is installed on the side wall of the energy storage cabinet to exhaust the cooled air from the cooling chamber.
[0006] Preferably, the circulating cooling component includes a ventilation mesh opening on the small fireproof door leaf, an air inlet pipe connected to one side of the ventilation mesh opening, a fan fixedly connected to one end of the air inlet pipe, and the air outlet of the fan communicating with the battery chamber through a pipe passing through the fireproof partition.
[0007] Preferably, the fan is fixedly installed at the bottom of the cooling chamber, a dustproof net is installed at the air inlet of the ventilation mesh, the air inlet pipe is fixedly installed on the inner side wall of the small fireproof door, and the end of the fan outlet pipe is located below the fireproof partition.
[0008] Preferably, the exhaust assembly includes an exhaust duct located above the interior of the cooling chamber, with one end installed through the side wall of the energy storage cabinet and the other end installed through the fireproof partition and communicating with the interior of the battery chamber. A smoke sensor is fixedly installed on the inner top of the exhaust duct near the fireproof partition.
[0009] Preferably, a fireproof mesh is bolted to one end of the exhaust pipe located in the battery cavity, and a protective mesh is bolted to the other end.
[0010] Preferably, both the large and small fireproof door panels are equipped with fireproof and waterproof locks, and the hinges are fireproof and waterproof hinges.
[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a fireproof partition with two independent fireproof doors.

Detailed Implementation
[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-4 This utility model provides a technical solution: A fireproof door that provides circulating cooling for an energy storage cabinet includes an energy storage cabinet 1, a fireproof partition 2, a large fireproof door leaf 3, a small fireproof door leaf 4, a hinge 5, a circulating cooling component 6, and an exhaust component 7. The fireproof partition 2 is fixedly installed inside the energy storage cabinet 1. The energy storage cabinet 1 is divided into a battery cavity and a cooling cavity. The battery cavity is used to install battery packs. The large fireproof door leaf 3 is hinged to one side of the battery cavity via the hinge 5, and the small fireproof door leaf 4 is hinged to one side of the cooling cavity via the hinge 5. The circulating cooling component 6 is installed inside the cooling chamber to cool the inside of the battery chamber, and the exhaust component 7 is installed on the side wall of the energy storage cabinet 1 to exhaust the cooled air from the cooling chamber.
[0016] The energy storage cabinet 1 is divided into an independent battery chamber (for housing the battery pack) and a cooling chamber (for installing the circulating cooling component 6) by a fireproof partition 2. A large fireproof door 3 (to enclose the battery chamber) and a small fireproof door 4 (to assist in ventilation of the cooling chamber) are correspondingly configured. Both can be flexibly opened and closed by hinges 5. The independent design of the dual chambers realizes functional zoning. The battery pack and the cooling equipment are physically isolated to avoid equipment interference and reduce the impact of the high temperature of the battery pack on the cooling component. The large and small doors correspond to different chambers and can be operated independently, which facilitates the inspection and maintenance of the battery pack or the cooling component without affecting each other, thus improving maintenance convenience.
[0017] In an optional embodiment: the circulating cooling component 6 includes a ventilation mesh 61 opened on the small fireproof door 4, one side of the ventilation mesh 61 is connected to an air inlet pipe 62, one end of the air inlet pipe 62 is fixedly connected to a fan 63, and the air outlet of the fan 63 is connected to the battery chamber through a pipe passing through the fireproof partition 2.
[0018] It should be noted that the fan 63 provides power to directionally deliver cold air from the outside to the battery pack inside the battery cavity, directly cooling the battery pack and forming a directional, closed air intake channel to prevent external impurities from entering the battery cavity in a disorderly manner, thereby improving cooling efficiency. As a power source, the fan 63 can adjust the air volume according to the battery pack temperature to ensure a stable and controllable cooling effect, thus solving the problem of insufficient cooling efficiency of natural ventilation.
[0019] In an optional embodiment: the fan 63 is fixedly installed at the bottom of the cooling chamber, the air inlet of the ventilation mesh 61 is equipped with a dustproof net, the air inlet pipe 62 is fixedly installed on the inner side wall of the small fireproof door 4, and the end of the pipe at the air outlet of the fan 63 is located below the fireproof partition 2.
[0020] It should be noted that the dustproof mesh of the ventilation mesh 61 can filter external dust and particulate matter, preventing them from entering the fan 63 or the battery cavity; the air inlet pipe 62 is fixed to the inside of the small fireproof door 4 to ensure a tight connection with the ventilation mesh 61, reducing air leakage, ensuring air intake efficiency, and avoiding air volume loss; the air outlet pipe of the fan 63 allows cooling air to enter from the bottom of the battery cavity, using the principle of hot air rising to promote air circulation in the battery cavity; the dustproof mesh extends the service life of the fan 63 and the battery pack, reducing equipment failures caused by dust accumulation; the air outlet position is designed in accordance with the air flow law, making the cooling inside the battery cavity more uniform and avoiding local high temperatures.
[0021] In an optional embodiment: the exhaust assembly 7 includes an exhaust pipe 71, which is located above the interior of the cooling chamber. One end of the exhaust pipe 71 is installed through the side wall of the energy storage cabinet 1, and the other end is installed through the fireproof partition 2 and communicates with the interior of the battery chamber. A smoke sensor 72 is fixedly installed on the inner top of the exhaust pipe 71 near the fireproof partition 2.
[0022] It should be noted that the exhaust pipe 71 of the exhaust assembly 7 connects the battery chamber to the outside, exhausting the hot air after the battery pack has cooled down, and improving the exhaust efficiency by utilizing the natural rising characteristic of hot air; the smoke sensor 72 monitors in real time whether there is a fire (smoke) in the battery chamber, providing a basis for safety warning.
[0023] The exhaust duct 71 works in conjunction with the circulating cooling component 6 to form a complete air circulation of "air intake → cooling → exhaust", ensuring continuous and effective heat dissipation and preventing hot air from accumulating in the battery cavity; the smoke sensor 72 is electrically connected to the external control system, enabling early fire detection. Compared with the traditional method of relying on external alarms, the response is faster, buying time for the initial fire response.
[0024] In an optional embodiment: a fireproof net 73 is bolted to one end of the exhaust pipe 71 located in the battery cavity, and a protective net 74 is bolted to the other end.
[0025] It should be noted that the fireproof net 73 is made of high-temperature resistant material. Under normal ventilation conditions, it does not affect exhaust air. In the event of a fire, it can prevent flames or sparks from spreading to the outside through the exhaust duct 71. A protective net 74 is installed at the end closest to the outside to prevent external debris (such as leaves or small animals) from entering the exhaust duct and blocking the passage. At the same time, it prevents personnel from contacting the internal structure of the exhaust duct. The fireproof net 73 enhances the fire safety of the exhaust duct 71, meets the core functional requirements of fire doors, and prevents fire from overflowing through the exhaust path. The protective net 74 ensures the unobstructed flow of the exhaust passage, reduces the decrease in heat dissipation efficiency caused by blockage, and improves the safety of equipment use.
[0026] In an optional embodiment: both the large fireproof door leaf 3 and the small fireproof door leaf 4 are equipped with fireproof and waterproof locks 8, and the hinges 5 are set as fireproof and waterproof hinges.
[0027] It should be noted that the fireproof and waterproof lock 8 ensures the sealing and locking reliability of the door when closed, while maintaining stable function in high temperature or humid environments; the hinge 5 adopts a fireproof and waterproof design to ensure that the door can still be opened and closed flexibly in fire or humid conditions, avoiding door jamming due to rust or high temperature deformation. The fireproof and waterproof lock 8 and hinge 5 improve the overall fireproof and waterproof performance of the door, adapting to the complex environment that the energy storage cabinet may face (such as outdoor humidity, high temperature fire); ensuring that the door can work reliably in normal use or emergency situations (such as closing and isolating during a fire), thus strengthening the safety protection capability of the fire door.
[0028] Working principle: When this utility model is used, the battery pack is installed in the battery cavity. The large fireproof door 3 is installed on the battery cavity to prevent the battery pack from overflowing after a fire. The small fireproof door 4 has ventilation mesh 61. The fan 63 in the circulating cooling component 6 and the air inlet pipe 62 provide circulating cooling for the battery pack in the battery cavity. The exhaust assembly 7 works in conjunction with the circulating cooling assembly 6 to exhaust the cooled air from the battery compartment through the exhaust duct 71. At the same time, the smoke sensor 72 can monitor the smoke concentration in the exhaust air in the exhaust duct 71 in real time. Once the battery pack spontaneously combusts or other abnormal situations that generate smoke, the smoke sensor 72 will immediately sense it and send a signal to the control system. The control system will promptly issue an alarm signal to remind the staff to take appropriate measures, thus buying valuable time for fire extinguishing and personnel evacuation, and greatly improving the fire safety of the energy storage cabinet.
[0029] The control method in this application is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, this application is mainly used to protect the structure and shape and their combination, so the control method and circuit connection will not be explained in detail in this application.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
