[0054] The following combination Figure 1-Figure 4 The present invention describes a liquid-cooled energy storage battery compartment fire-fighting device according to an embodiment of the present invention.

[0055] The embodiment of the present invention provides a liquid-cooled energy storage battery compartment fire-fighting device, such as Figures 1 to 3 As shown, the liquid-cooled energy storage battery compartment fire-fighting device includes a battery compartment 100, a battery module 110, a first liquid-cooling component 120, a second liquid-cooling component, a fire detection component and a fire extinguishing component.

[0056] Among them, the battery module 110 is arranged inside the battery compartment 100; the first liquid cooling component 120 is arranged on the bottom wall of the battery compartment 100; the second liquid cooling component is arranged on the side wall of the battery compartment 100, and the second liquid cooling component is connected to the first liquid cooling component 120 to form a circulation loop; the fire detection component is used to monitor fire information; the fire extinguishing component is arranged in the battery compartment 100, and the outlet of the fire extinguishing component is facing the battery module 110.

[0057] It will be appreciated that the battery compartment 100 is the fundamental structure of the entire device, housing and protecting the battery module 110. The battery module 110 is the core component of the energy storage battery compartment 100, and its performance and safety directly impact the stable operation of the entire system. To ensure the safe and reliable operation of the battery module 110 under various operating conditions, the liquid-cooled energy storage battery compartment firefighting device in this embodiment employs multiple safety measures.

[0058] Specifically, the first liquid cooling component 120 and the second liquid cooling component together constitute an efficient cooling system, which quickly conducts and dissipates the heat generated by the battery module 110, thereby keeping the battery module 110 operating within an appropriate temperature range; and monitors the environmental changes in the battery compartment 100 in real time through the fire detection component; once an abnormal situation is detected, such as smoke or abnormally high temperature, the fire detection component will immediately sound an alarm and trigger the fire extinguishing component to extinguish the fire; once the fire detection component sounds an alarm, the fire extinguishing component sprays fire extinguishing agent onto the battery module 110 to quickly extinguish the initial fire and prevent the fire from spreading.

[0059] The liquid-cooled energy storage battery compartment fire-fighting device provided by the embodiment of the present invention monitors environmental changes in the battery compartment 100 in real time through the fire detection component. When an abnormal situation is detected, the fire extinguishing component sprays a fire extinguishing agent into the battery module 110 to quickly extinguish the initial fire, thereby effectively controlling the spread of the fire. In addition, the heat generated by the battery module 110 is quickly conducted and dissipated through the first liquid cooling component 120 and the second liquid cooling component, thereby keeping the battery module 110 within a suitable temperature range, effectively ensuring the safety of the battery module 110.

[0060] In one embodiment of the present invention, Figure 1 and Figure 3 As shown, the first liquid cooling component 120 is located on the inner bottom wall of the battery compartment 100; the first liquid cooling component 120 includes a cooling plate 121 and a liquid cooling channel, and the cooling plate 121 is arranged on the inner bottom wall of the battery compartment 100; the liquid cooling channel is constructed inside the cooling plate 121, and one end of the liquid cooling channel has a liquid inlet, and the other end of the liquid cooling channel has a liquid outlet.

[0061] Specifically, the cooling plate 121 is laid on the inner bottom wall of the battery compartment 100, and the liquid cooling channel is serpentine. The serpentine liquid cooling channel 122 is opened inside the cooling plate 121, and one end of the serpentine liquid cooling channel 122 has a liquid inlet, and the other end of the serpentine liquid cooling channel 122 has a liquid outlet.

[0062] Optionally, the cooling plate 121 is made of a material with high thermal conductivity, such as aluminum alloy or copper alloy, to ensure that heat can be quickly transferred from the battery module 110 to the coolant. The serpentine liquid cooling channel 122 can ensure that the coolant flows evenly in the channel to avoid local overheating.

[0063] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the second liquid cooling assembly is located on the outer wall of the battery compartment 100. The second liquid cooling assembly includes a cooling pipe 131, a coolant pump and a radiator. The cooling pipe 131 is spirally wrapped around the outer wall of the battery compartment 100. The liquid outlet end of the cooling pipe 131 is connected to the liquid inlet, and the liquid inlet end of the cooling pipe 131 is connected to the liquid outlet; the coolant pump is arranged in the cooling pipe 131; and the radiator is arranged in the cooling pipe 131.

[0064] Specifically, the cooling pipe 131 is spirally arranged along the outer wall of the battery compartment 100 , the liquid outlet of the cooling pipe 131 is connected to the liquid inlet, and the liquid inlet of the cooling pipe 131 is connected to the liquid outlet.

[0065] There are two coolant pumps, both of which are located in the cooling pipeline 131 , and the two coolant pumps are respectively close to the liquid inlet end and the liquid outlet end of the cooling pipeline 131 .

[0066] The radiator is located at the liquid outlet end of the cooling pipeline 131 and at a side away from the liquid inlet, and the radiator is communicated with the cooling pipeline 131 .

[0067] It is understandable that the function of the coolant pump is to promote the circulation of the coolant in the cooling pipe 131, ensuring that the coolant can continuously absorb heat from the battery module 110 and transfer it to the radiator. The two pump bodies of the coolant pump are respectively arranged at the liquid inlet and liquid outlet of the cooling pipe 131, which can effectively ensure the uniform flow of the coolant in the pipe and avoid the decrease in cooling efficiency due to uneven flow. The function of the radiator is to dissipate the heat in the coolant to the external environment. It is usually made of a material with high heat exchange efficiency, such as an aluminum heat sink, which has a large surface area and helps to improve the heat dissipation effect. The radiator is connected to the cooling pipe 131. After the coolant absorbs heat from the battery module 110, it is transported to the radiator through the coolant pump, and the heat is dissipated into the air through the surface of the radiator.

[0068] The liquid-cooled energy storage battery compartment fire-fighting device provided in the embodiment of the present invention comprises a first liquid-cooling assembly 120 and a second liquid-cooling assembly together forming an efficient cooling system, which rapidly conducts and dissipates the heat generated by the battery module 110 through the cooling plate 121 and the serpentine liquid-cooling channel 122; the coolant in the cooling pipe 131 absorbs heat during the circulation process and transfers the heat to the external environment through the second liquid-cooling assembly, thereby keeping the battery module 110 operating within a suitable temperature range.

[0069] In one embodiment of the present invention, Figure 1 As shown, the fire detection component includes a fire alarm 143 and a fire detection element. The fire alarm 143 is connected to the fire detection element and is arranged on the outer wall of the battery compartment 100; the fire detection element includes a smoke detector 141 and / or a temperature sensor 142. The smoke detector 141 is arranged on the inner wall of the battery compartment 100, and the temperature sensor 142 is arranged on the battery module 110.

[0070] Specifically, the fire detection components include:

[0071] There are a plurality of smoke detectors 141 , and the plurality of smoke detectors 141 are evenly distributed on the inner wall of the battery compartment 100 ;

[0072] There are a plurality of temperature sensors 142 , and the plurality of temperature sensors 142 are evenly arranged on the surface of the battery module 110 ;

[0073] The fire alarm 143 is located on the outer top wall of the battery compartment 100 , and is connected to the smoke detector 141 and the temperature sensor 142 .

[0074] As will be appreciated, smoke detector 141 can detect smoke generated within battery compartment 100, promptly identifying early signs of fire. Temperature sensor 142 monitors the surface temperature of battery module 110 in real time, sounding an alarm if the temperature exceeds the normal range. Fire alarm 143, the core component of the fire detection assembly, receives signals from smoke detector 141 and temperature sensor 142 and, upon detecting signs of fire, issues an audible and visual alarm, alerting operators or automatically triggering the firefighting system for emergency response.

[0075] The liquid-cooled energy storage battery compartment fire-fighting device provided in the embodiment of the present invention can monitor the environmental changes in the battery compartment 100 in real time through the smoke detector 141 and the temperature sensor 142. Once an abnormal situation is detected, the fire alarm 143 will sound an alarm and trigger the fire extinguishing component to extinguish the fire, quickly extinguishing the initial fire and effectively controlling the spread of the fire.

[0076] In one embodiment of the present invention, Figure 1As shown, there are a plurality of battery modules 110 , and a first interval is provided between two adjacent battery modules 110 .

[0077] It can be understood that there are several battery modules 110, and several battery modules 110 are arranged inside the battery compartment 100, and the two ends of the battery module 110 are respectively connected to the inner top wall and the inner bottom wall of the battery compartment 100. The several battery modules 110 are arranged at equal intervals, and the same first interval is set between every two adjacent battery modules 110.

[0078] Further, such as Figure 1 As shown, the fire extinguishing assembly includes a fire extinguishing agent storage tank 151 and a nozzle 152. The fire extinguishing agent storage tank 151 is set in the battery compartment 100; one end of the nozzle 152 is connected to the fire extinguishing agent storage tank 151, and the other end of the nozzle 152 faces the first interval.

[0079] Specifically, there are several fire extinguishing agent storage tanks 151, and several fire extinguishing agent storage tanks are evenly arranged on the top of the battery compartment 100 along the horizontal direction; there are multiple nozzles 152 that are compatible with the fire extinguishing agent storage tanks 151, and the nozzles 152 are located on the inner top wall of the battery compartment 100, and one end of the nozzle 152 is connected to the bottom end of the corresponding fire extinguishing agent storage tank 151, and the other end of the nozzle 152 faces the first interval.

[0080] It is understandable that the fire extinguishing component is connected to the control system, and the high-pressure fire extinguishing agent filled in the fire extinguishing agent storage tank 151, such as inert gas carbon dioxide or high-efficiency dry powder, can be quickly released after receiving the command of the control system. Each fire extinguishing agent storage tank 151 is equipped with an independent release valve to ensure that it can be accurately and quickly sprayed at the fire source when a fire occurs. In addition, the uniform distribution design of the fire extinguishing agent storage tank 151 enables the fire extinguishing agent to cover every corner of the battery compartment 100, thereby improving the fire extinguishing efficiency. The nozzle 152 is a key component for the release of the fire extinguishing agent, and its design fully considers the spraying angle and coverage range. The nozzle of the nozzle 152 is directed towards the dense area of ​​the battery module 110 to ensure that the fire extinguishing agent can directly act on the fire source and quickly reduce the fire. At the same time, the material of the nozzle 152 is a special alloy that is resistant to high temperature and corrosion to ensure that it can still work normally in a high-temperature environment of a fire.

[0081] It should be noted that once the fire detection component sounds an alarm, the control system immediately activates the fire extinguishing component to automatically extinguish the fire. First, the control system analyzes the fire source location and fire intensity based on data from the smoke detector 141 and temperature sensor 142. The control system then sends a release command to the corresponding fire extinguishing agent storage tank 151 and simultaneously activates the sprinkler 152 to spray. The fire source is quickly extinguished and the fire is effectively contained.

[0082] The liquid-cooled energy storage battery compartment fire-fighting device provided by the embodiment of the present invention controls the nozzle 152 to spray fire extinguishing agent toward the battery module 110 when the fire detection component sounds an alarm, thereby quickly extinguishing the initial fire and preventing the fire from spreading.

[0083] In one embodiment of the present invention, the fire-fighting device further includes a first ventilation assembly, which is located on the top of the battery compartment 100 and faces the first compartment, and is located on one side of the fire-extinguishing assembly.

[0084] Optional, such as Figure 1 As shown, the first ventilation assembly includes a first ventilation hole and a first ventilation duct 161; the first ventilation hole is opened on the top of the battery compartment 100, and the first ventilation hole is located on one side of the fire extinguishing agent storage tank 151; one end of the first ventilation duct 161 is connected to the first ventilation hole, and the other end of the first ventilation duct 161 extends to the interior of the battery compartment 100.

[0085] Furthermore, the first ventilation component also includes an exhaust fan 162 and a first motor. The exhaust fan 162 is located inside the first ventilation duct 161 . The first motor is located inside the first ventilation duct 161 , and the output end of the first motor is connected to the exhaust fan 162 .

[0086] As can be appreciated, the design of the first ventilation assembly cleverly and effectively exhausts hot air from the battery compartment 100. Through the channel formed by the first vents and the first ventilation duct 161, combined with the powerful exhaust action of the exhaust fan 162, the heat accumulated around the battery module 110 is quickly removed. The first motor, serving as the power source, drives the exhaust fan 162 at high speed, generating a powerful airflow that ensures smooth exhaust of hot air, thereby maintaining a suitable working environment within the battery compartment 100.

[0087] In one embodiment of the present invention, Figure 1 and Figure 4 As shown, the fire-fighting device further includes a second ventilation assembly; the second ventilation assembly is located on the outer wall of the battery compartment 100, and the second ventilation assembly is spaced apart from the second liquid cooling assembly.

[0088] Optionally, the second ventilation assembly includes a second ventilation hole 171 and a second ventilation duct 172; the second ventilation hole 171 is spaced apart from the second liquid cooling assembly; one end of the second ventilation duct 172 is connected to the second ventilation hole 171, and the other end of the second ventilation duct 172 extends to the outside of the battery compartment 100, and heat dissipation grooves 1721 are provided along the length direction of the second ventilation duct 172.

[0089] Specifically, there are a plurality of second ventilation holes 171, and the plurality of second ventilation holes 171 are arranged in sequence along the water flow direction of the cooling pipe 131, and the second ventilation holes 171 and the cooling pipe 131 are arranged at intervals; one end of the second ventilation duct 172 is connected to the second ventilation holes 171, and the other end of the second ventilation duct 172 extends to the outside of the battery compartment 100, and heat dissipation grooves 1721 are provided along the length direction of the second ventilation duct 172.

[0090] It can be understood that the second ventilation assembly further improves the heat dissipation efficiency and overall ventilation effect of the battery compartment 100. By arranging a plurality of second ventilation holes 171 along the water flow direction of the cooling pipe 131, and the second ventilation duct 172 connected thereto, an efficient heat dissipation duct network is constructed. This not only helps to accelerate the circulation of air around the cooling pipe 131, but also effectively takes away the excess heat dissipated by the circulation of the coolant, further reducing the operating temperature of the battery module 110. With the layout in which each second ventilation hole 171 is spaced apart from the cooling pipe 131, it is ensured that heat can be discharged from the battery compartment 100 evenly and efficiently. At the same time, the heat dissipation groove 1721 opened on the second ventilation duct 172 further increases the contact area between the air and the pipe wall, improves the heat exchange efficiency, and enables heat to be transferred to the external environment faster.

[0091] The liquid-cooled energy storage battery compartment fire-fighting device provided in the embodiment of the present invention, the first ventilation component and the second ventilation component are responsible for the air circulation inside and outside the battery compartment 100, the hot air inside the battery compartment 100 is discharged through the first ventilation hole and the first ventilation duct 161, and the external cold air is introduced through the second ventilation hole 171 and the second ventilation duct 172, forming an effective air circulation, ensuring that the temperature and humidity inside the battery compartment 100 are maintained within a safe range.

[0092] In one embodiment of the present invention, the fire-fighting device further includes a control system, which is located outside the battery compartment 100 and is connected to the first liquid cooling component 120, the second liquid cooling component, the fire detection component, the fire extinguishing component and the first ventilation component.

[0093] As the core brain of the entire liquid-cooled energy storage battery compartment firefighting system, the control system plays a crucial role. Integrating advanced sensor technology, data processing algorithms, and intelligent control logic, it monitors key parameters within the battery compartment 100 in real time, including temperature, smoke concentration, and fire extinguishing agent reserves, and rapidly responds and makes decisions based on pre-set safety strategies.

[0094] It is understandable that the control system first receives real-time data from the smoke detector 141 and the temperature sensor 142 through a close connection with the fire detection component. After the algorithm analysis of these data, potential fire risks or fire situations that have already occurred can be quickly identified. Once an abnormal situation is detected, the control system will immediately trigger the sound and light alarm, and at the same time send an emergency alarm signal to the remote monitoring center through the communication interface to ensure that the fire information can be conveyed to the relevant personnel in a timely manner. After confirming the occurrence of the fire, the control system will quickly start the automatic fire extinguishing process. It accurately determines the location of the fire source and the size of the fire based on the data provided by the fire detection component, and then sends a release instruction to the corresponding fire extinguishing agent storage tank 151. At the same time, the control system will also adjust the spray angle and intensity of the nozzle 152 to ensure that the fire extinguishing agent can cover the fire source in the most effective way and quickly extinguish the fire. During the fire extinguishing process, the control system will also continue to monitor changes in the fire situation and adjust the fire extinguishing strategy as needed to ensure that the fire is thoroughly controlled.

[0095] In one embodiment of the present invention, the fire-fighting device further includes a heat-insulating layer, which is disposed on the inner wall of the battery compartment 100 .

[0096] Specifically, the heat insulation layer is located on the inner side walls and the inner top wall of the battery compartment 100 .

[0097] It is understood that the design of the thermal insulation layer fully considers the safety requirements of the battery compartment 100 in the event of a fire. The thermal insulation layer uses high-efficiency thermal insulation materials such as ceramic fiber, asbestos, or special composite materials to effectively block high temperatures and prevent the spread of fire to the outside of the battery compartment 100. In addition, the uniform laying of the thermal insulation layer ensures that the inner walls and inner top wall of the entire battery compartment 100 have good thermal insulation properties, thereby providing a relatively safe environment for the battery module 110 and effectively protecting the structural integrity of the battery compartment 100 even in the event of a fire.

[0098] In summary, the liquid-cooled energy storage battery compartment fire-fighting device with multiple safety protections provided in this embodiment can respond quickly when a fire occurs, effectively control the fire, and ensure the safety of the battery module 110.

[0099] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
