Stainless steel integrated 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 stainless steel battery box nozzle adopts an integrated structure, which is simple and firm in structure and easy to install. The nozzle shell is made of stainless steel 304, and part of it is made of 316F. Stainless steel battery box nozzles have the characteristics of high temperature resistance and corrosion resistance, and are widely used in the fire protection industry.

Features of stainless steel battery box nozzle:

Material used: stainless steel (main material is 304)

Structure type: one-piece structure

Usage medium: perfluorohexanone, water and other fire extinguishing agents

Connection thread size: R1/4

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.

Stainless steel battery box nozzle selection table:

Stainless steel 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.

Stainless steel 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.

The main functions of stainless steel battery box nozzle:

Fire sprinklers in the Energy Storage Pack battery box have multiple functions that confirm the safety of the energy storage system in the event of a fire risk:

1. Fire detection: Some fire sprinklers are equipped with fire detection systems that can monitor the temperature and smoke inside the battery box. If an abnormality is detected, the sprinkler head will automatically start to quickly extinguish the fire source.

2. Fire extinguishing: When a fire breaks out, fire sprinklers will spray foam or water to control the source of the fire and prevent the spread of the fire. The use of foam can effectively extinguish fires while reducing the potential harm of water to the battery system.

3. Cooling: The energy storage pack battery box will generate heat during the charging and discharging process. Fire sprinklers can cool the battery box with water or foam to prevent overheating and reduce the risk of fire.

4. Prevent the spread of fire: The location and design of the fire sprinkler can prevent the fire from spreading to other parts of the battery box or equipment, thereby reducing the scope of the fire.
