Aluminum alloy battery box nozzle

The battery box automatic fire extinguishing device consists of an alarm system, perfluorohexanone supply equipment, partition valves, pipelines, nozzles, etc. It can be widely used in energy storage power stations and new energy vehicle battery box fire extinguishing. The nozzle structure and interface form can be customized according to customer requirements, and good atomization effect is confirmed. When the perfluorohexanone fire extinguishing agent cannot extinguish the fire, the nozzle can also be switched to water spray.

The aluminum alloy battery box nozzle is a commonly used nozzle for pack-level protection of energy storage containers. The nozzle shell is made of 6061 aluminum, and other parts are made of stainless steel 304 or 316F. The aluminum alloy battery box nozzle has good corrosion resistance and can maintain the stability of the surface coating when exposed to chemical substances such as air and water, and will not be further corroded. And aluminum has the advantages of explosion-proof, fire-proof and fire-fighting safety. It has good formability, low low-temperature performance, but high heat capacity, so it can absorb more heat, lower the combustion temperature, and delay the spread of fire.

Features of aluminum alloy battery box nozzle:

Material used: aluminum (main material is 6061 aluminum)

Structural advantages:

1. The sprinkler head designed for pack-level fire extinguishing systems has high efficiency atomization, rapid cooling, and effectively prevents thermal runaway. It is suitable for media such as perfluorohexanone and water.

2. It has good pressure resistance and air tightness, and can reach a protection level of IP67 or above.

3. Compact structure and easy to install.

Aluminum alloy battery box nozzle selection table:

Aluminum alloy battery box nozzles are mainly used to extinguish fires in energy storage power stations and new energy vehicle battery boxes. Some commonly used models have been developed based on the application requirements of these scenarios, and system integration manufacturers can choose according to their needs.

Aluminum alloy battery box nozzle application scenarios:

Battery box nozzles are mainly used in large-scale and distributed energy storage power stations, mobile energy storage vehicles, backup power storage stations, and fire protection systems covering the entire industry chain of power generation, transmission and transformation, electricity sales and electricity consumption. Although electrochemical energy storage devices represented by ion batteries have various advantages, potassium metal is the most reactive metal among known elements (including radioactive elements). Thermal runaway phenomena occur from time to time in the automotive field, posing safety risks for the application of lithium batteries in energy storage. As the last passive defense system, fire protection’s reasonable design, material selection, layout and construction directly affect the healthy development of the energy storage industry.

Pack battery box fire extinguishing system fire extinguishing principle:

Energy Storage Pack Battery Box Sprinkler Fire Suppression is a fire suppression technology that extinguishes flames by releasing extinguishing agents when a fire breaks out. The following is the principle of energy storage pack battery box nozzle fire extinguishing:

1. Fire detection: The energy storage system is equipped with a fire detection system, which usually uses temperature sensors, smoke detectors, gas sensors and other devices to monitor abnormal conditions in the battery box. Once signs of fire are detected, the system will activate the sprinkler extinguishing program.

2. Fire extinguishing agent storage: The energy storage system has a built-in fire extinguishing agent storage device, usually a pressure tank or storage tank. Extinguishing media can be dry powder, gas or liquid, the choice depends on the design and needs of the system.

3. Nozzle release: Once the fire detection system triggers an alarm, the fire extinguishing agent in the storage device will be transported to the specific sprinkler head through the pipeline system. These nozzles are usually located inside the battery box to ensure that the fire extinguishing agent can be sprayed directly near the fire source.

4. Fire extinguishing agent extinguishes the fire source: Once the nozzle releases the fire extinguishing agent, the fire extinguishing agent will quickly cover the fire source, lower the flame temperature and weaken the fire intensity. Different types of fire extinguishing agents have different fire extinguishing mechanisms, but their goals are to extinguish or control the fire source.

5. System monitoring: Once the sprinkler nozzle releases the fire extinguishing agent, the system will continue to monitor the fire source to confirm that the fire is effectively extinguished. The system can also send alerts to notify operations personnel or the fire department so they can take further action.
