Description

DK 180794 B1 1 [Fire extinguishing apparatus] Field of the Invention The present invention relates to a fire extinguishing apparatus for extinguishing fires in vehicles. Background of the Invention It is a well-known fact that vehicles may have a risk of catching or initiating fire. Safety is a very important issue when limiting, containing and/or putting out the fire, especially for the people and surroundings involved in the process.
When looking towards electric vehicles, a new issue occurs regarding safety of lithi- um-ion batteries and the risk of initiating fire. The safety of lithium-ion batteries in vehicles is a priority of the automotive industry.
One example may be lithium-ion batteries that may suffer thermal runaway and cell rupture if overheated or overcharged. In extreme cases, the thermal runaway and cell rupture may lead to combustion. To reduce these risks, lithium-ion battery packs con- tain fail-safe circuitry that shuts down the battery when the temperature of the battery is outside the safe range. When handled improperly, or if manufactured defectively, some rechargeable batteries can experience thermal runaway resulting in overheating. Sealed cells will sometimes explode violently if safety vents are overwhelmed or non- functional.
Another example may be a lithium-ion battery that may be damaged, for example when the electric vehicle runs over some debris, and the driver might not be aware of the damage. And then a fire may start well after the initial incident. That could theo- retically cause a fire after the electric vehicle is parked in a garage or in a vehicle park. The lithium-ion cells may cause and explosion or a fire may occur.
The electric vehicles and their lithium-ion batteries are hazardous. Fires from electric vehicle batteries can burn for hours or even days, and sometimes reigniting after fire- fighters think the blaze is over. The fire in electric vehicles may cause a huge risk for
DK 180794 B1 2 the firefighters involved in the process, especially if the electric vehicles are located for example in troubled locations, such as in vehicle parks, parking garages/basements or parking decks in ferries, where a plurality of vehicles are present with limited space between each vehicle.
Object of the Invention It is an object of the invention to provide a product and a method for extinguishing fire in a vehicle, especially when the vehicle is located in an area with limiting working space around the vehicle.
Description of the Invention The present invention addresses this by providing a fire extinguishing apparatus for extinguishing fires in vehicles, where the fire extinguishing apparatus comprises: - at least one bottom pipe, where said bottom pipe has at least one inlet opening and at least one closed end, the bottom pipe is provided with at least one nozzle, - at least a first side pipe and at least a second side pipe, each having at least one inlet opening and at least one closed end, said first side pipe and said second side pipe are provided with at least one nozzle each, and said first side pipe and said second side pipe are arranged substantially parallel to said bottom pipe, - an inlet distributor is arranged in fluid communication with the inlet opening in said bottom pipe and the inlet opening in said first side pipe and the inlet opening in said second side pipe, where said first side pipe is arranged on a first side relative to the bottom pipe and said second side pipe is arranged on a second side relative to the bottom pipe, such that the bottom pipe is arranged between the first and second side pipes, where in use the inlet distributor is capable of distributing fluid to said bottom pipe and said first side pipe and said second side pipe, so that the fluid flows through the nozzles of said bottom pipe and the nozzles of said first side pipeand the nozzles of said second side pipe, into a fire extinguishing zone, where said first side pipe and said second side pipe are arranged in an equally elevated position relative to said bottom pipe, forming a part of said fire extinguishing zone between the bottom pipe and said first side pipe and said second side pipe, and the nozzles of said bottom pipe and the nozzles of said first side pipe and the nozzles of said second side pipe are directed substantially towards said part of said fire extin- guishing zone.
DK 180794 B1 3 Fire incidents in electric vehicles occur relatively frequently.
Fire in electric vehicles where the lithium-ion battery is ignited is in some areas more challenging than in or- dinary vehicle fires.
Fven when the battery fire is obvious, it is well-known that it easily may take 24 hours for a lithium-ion battery fire in an electric vehicle to be fully extinguished.
Experience from fires in electric vehicles as well as a number of guides in the area uncovers the difficult challenges which may arise in handling a fire in the electric vehicle or any other types of vehicle.
If the vehicles are located in troubled locations, such as in vehicle parks, parking garages/basements, garage for repairs or parking decks in ferries, a fire may be more troublesome, because a plurality of vehi- cles are present with limited space between each vehicle.
The fire extinguishing appa- ratus easily fits between the vehicles.
With an electric vehicle fire, there is a need for water.
In many cases, modern fire de- partments use foam or dry chemicals that are better than water at suppressing fires.
While dry chemicals are great at putting down ordinary electrical fires, they may be ineffective with a fire stemming from a vehicles battery.
Water is therefore the best approach to a lithium-ion battery fire or any other battery in a vehicle.
The best way to extinguish fires in an electric vehicle is to keep a direct and focused stream on the battery until the battery relents and temperature is greatly decreased.
If the battery is placed under the hood, it is relatively easy to extinguish a fire.
It is much more difficult if the battery is positioned in the rear part of the vehicle or direct- ly in the middle under the vehicle.
The fire extinguishing apparatus may therefore be arranged under and around the electric vehicle, by placing the electric vehicle in a controllable fire extinguishing zone provided by the fire extinguishing apparatus.
The fire extinguishing apparatus comprises a bottom pipe or bottom pipes, which may be arranged under a vehicle.
The fire extinguishing apparatus also comprises side pipes, where the side pipes may be arranged on each side of the vehicle.
A first side pipe or first side pipes is arranged on one side of the vehicle, and a second side pipe or second side pipes is arranged on the other side of the vehicle.
The bottom pipe or pipes and the side pipes are arranged along the longitudinal direction of the vehicle.
DK 180794 B1 4 The bottom pipe or pipes may have inlet openings and closed ends. The side pipes may also be provided with inlet openings and closed ends. The pipes may contain a fluid such as water or similar. The bottom pipe or pipes are provided with at least one nozzle each, preferably a plurality of nozzles arranged in a predefined pattern along the bottom pipe or pipes. The nozzles are directed toward the vehicle. The side pipe or pipes may also be provided with at least one nozzle each, preferably a plurality of nozzles arranged in a predefined pattern along the side pipe or pipes. The nozzles are directed towards the vehicle.
The inlet distributor is arranged in fluid communication with the inlet openings in the bottom pipe and the side pipes. The inlet distributor is capable of distributing fluid too so the fluid flows through the nozzles of the bottom pipe or pipes and through the nozzles of the side pipes. The fluid is directed towards the vehicle, which is arranged in the fire extinguishing zone of the fire extinguishing apparatus.
The first side pipe or pipes and the second side pipe or pipes are arranged in an equal- ly elevated position relative to said bottom pipe. The space between the pipes forms a U-shaped fire extinguishing apparatus. The space in the U-forms the fire extinguishing zone or a part of the fire extinguishing zone. The nozzles of the bottom pipe or pipes and the nozzles of all the side pipe or pipes are directed substantially towards the ve- hicle arranged in the fire extinguishing zone.
In a further advantageous embodiment of the invention, a first pipe pair comprising said first side pipe and said second side pipe is arranged in a first position relative to said bottom pipe, and a second pipe pair comprising said first side pipe and said sec- ond side pipe is arranged in a second position relative to said bottom pipe.
