Copper 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 copper alloy battery box nozzle is a commonly used nozzle for pack-level protection of energy storage containers. The nozzle shell is made of HPb59-1 or HPb57-3 copper, and other parts are made of stainless steel 304 or 316F. The surface of the nozzle is electroless nickel plated. This battery box nozzle is resistant to neutral salt spray for more than 360H (GB/T1025-2012), or the copper accelerated acetic salt spray test for more than 36H.

Features of copper alloy battery box nozzle:

Material used: copper (main material HPb59-1 or HPb57-3)

Surface treatment: copper nickel plated

Structure type: split structure

Connection thread size: M16*1.5

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.

Copper alloy battery box nozzle selection table:

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

Copper 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.
