TECHNICAL FIELD
[0001] The present invention relates to a fire extinguishing system for a vehicle, in particular
an emergency cooling system for an alternative drive vehicle, such as an electric
vehicle or a gas/hydrogen powered vehicle.
STATE OF THE KNOWN ART
[0002] As is known, the need to reduce the environmental impact of transport vehicles is
increasingly felt, especially heavy vehicles, such as public transport vehicles.
[0003] To this end, electric or alternative fuels such as gas, LNG (Liquid Natural Gas)
or CNG (Compressed Natural Gas) vehicles, which can be used on internal combustion
engines, or hydrogen, which can be used on fuel cell engines, are increasingly used.
[0004] As is known, electric vehicles comprise battery packs configured to provide a sufficient
source of electrical energy to allow traction of the vehicle as well as the operation
of other auxiliary comfort devices such as the air conditioning system or functional
devices, such as screens for displaying information useful to passengers.
[0005] Also as known, the electric batteries used in said vehicles are electrochemical storage
devices which, during use in charging and discharging, tend to heat up.
[0006] It is possible that the heating reaches levels such as to generate a phenomenon called
"thermal runaway" in which the temperature triggers exothermic reactions that further
raise the temperature and therefore consequently leading to disastrous consequences
such as explosions or fires that can involve the entire vehicle and its occupants.
[0007] In the case of gas or hydrogen vehicles, the fuel is normally housed in pressurized
tanks carried by the vehicle itself and made of steel or composite material to allow
the same to be sealed at high pressure, for example at a pressure greater than 100
bar.
[0008] However, it is known that hydrogen is an extremely volatile element, light and reactive
with the other elements of the atmosphere, mainly oxygen. Similarly, it is known that
the gas is susceptible to explosion.
[0009] In the event of an accident involving a vehicle comprising a pressurized gas or hydrogen
tank, a fire of such magnitude could occur that could cause the tank to explode and/or
the fire could spread to the rest of the vehicle, with consequent damage to property
or people in the immediate vicinity.
[0010] The need is therefore felt to provide, both in the case of electric vehicles and
in the case of gas/hydrogen vehicles, to suddenly cool the battery packs or the pressurized
tanks in order to avoid fire in the vehicle 1 and/or potential explosions.
[0011] However, especially in the case of public transport vehicles, said battery packs/pressurized
tanks are normally housed on the roof of the vehicle in order not to limit the space
suitable for passenger transport.
[0012] Said positioning makes it extremely difficult for rescuers to be able to effectively
cool the battery packs/pressurized tanks.
[0014] The need is therefore felt to provide fire extinguishing systems that can allow sudden
and easy cooling of the battery packs and/or pressurized tanks.
[0015] The object of the present invention is to satisfy the above requirements in an optimized
and inexpensive way.
SUMMARY OF THE INVENTION
[0016] The aforesaid object is achieved by a vehicle provided with a fire extinguishing
system as claimed in the attached claims.

drawings in which:
- Figure 1 is a perspective view illustrating a vehicle provided with a fire extinguishing
system according to the present invention;

DETAILED DESCRIPTION OF THE INVENTION
[0018] Figure 1 illustrates a vehicle 1, such as a vehicle for the public transport of people,
provided with a plurality of walls 2 defining an internal volume suitable for the
transport of passengers. As is known, said walls comprise a floor, not shown, a plurality
of side walls 2a, a front/rear wall 2b and a roof 2c.
[0019] In particular, the vehicle 1 comprises a plurality of energy storage means 4 carried
by the vehicle 1 itself and configured to define an energy source usable by driving
means (not illustrated) of the vehicle 1 allowing the operation thereof. Said energy
storage means 4 can be packs of electric batteries or compressed gas tanks such as
hydrogen or liquid natural gas, LNG (Liquid Natural Gas) or compressed natural gas,
CNG (Compressed Natural Gas).
[0020] In the accompanying illustrative figures, the vehicle 1 is an electric bus and the
energy storage means 4 comprise battery packs 5, however, as is clear from the following,
the present invention can be validly used if the energy storage means 4 were pressurized
tanks and the vehicle was of a different type.
[0021] As illustrated, the battery packs 5 are housed inside respective casing 6 fixed on
the roof 2c of the vehicle 1. Preferably, each casing 6 can be enclosed within a space
7 delimited by a lid 8 enclosing the various casings 6 so as to separate them from
the external environment.
[0022] In particular, each casing 6 can house inside the same, as is known, in addition
to the battery packs 5, relative cables and electronic elements necessary for the
transfer of electrical energy between the batteries and the driving means of the vehicle
1, not illustrated.
[0023] According to the invention, the vehicle 1 comprises a fire extinguishing system 10
comprising at least one hydraulic interface 11 configured to couple with a pipe configured
to inject a fire extinguishing fluid into the system 10, diffuser means 12 configured
to spray towards the energy storage means 4 the fluid injected by means of the hydraulic
interface 11 and a hydraulic distribution circuit 13 configured to fluidically connect
the hydraulic interface 11 with the diffuser means 12.
[0024] In greater detail, the fire extinguishing system 10 comprises a plurality of hydraulic
interfaces 11 advantageously obtained in the side walls 2a of the vehicle 1, preferably,
as in the case described, in the front and rear portion of the vehicle 1.
[0025] Preferably, these hydraulic interfaces 11 are made at a height close to the wheels
of the vehicle 1, advantageously between the wheels of the vehicle 1 and windows of
the vehicle in order to be at human height so as to allow rescuers to easily connect
a pipe with the hydraulic interface 11.
[0026] Specifically, each hydraulic interface 11 comprises an opening configured to allow
the insertion of a fire extinguishing type pipe or any pipe suitable for inserting
pressurized liquid. The fluid inserted can be water or any mixture of water and fire
extinguishing agents of a known type.
[0027] The hydraulic distribution circuit 13 advantageously comprises a network of pipes
14, made with a heat and combustion resistant material and configured to fluidically
connect the hydraulic interfaces 11 with the diffuser means 12.
[0028] Therefore, in the example illustrated, vertical pipes 14 are provided, carried by
the side walls 2a and connected directly to a respective hydraulic interface 11 and
horizontal pipes 14 carried by the roof 2c connected to the vertical pipes 14 and
to each diffuser means 12.
[0029] The diffuser means 12 according to the invention comprise at least one nozzle 16,
17, as described in the following and selectively connectable to an end portion of
a pipe 14 and facing a respective casing 6 of a battery pack 5.
[0030] Figure 2 illustrates an embodiment of the diffuser means 12 according to the invention.
In this embodiment the diffuser means 12 comprise a nozzle 16 configured to define
a direct jet of refrigerant fluid focusing on a limited area of the casing 6 of the
battery packs 5.
[0031] Consequently, to said shape of diffuser means 12, the casing 6 according to the invention
defines an opening 6a provided with a meltable element 15 configured to close the
opening 6a when the temperature of the battery pack 5 is lower than a predetermined
threshold temperature. If the temperature of the battery pack 5 is higher than the
predetermined threshold temperature, said meltable element 15 is configured to melt
and leave the opening 6a free so as to allow the latter to communicate with the space
7. In this way, the jet of refrigerant fluid coming from the nozzle 16 can penetrate
inside the battery pack 5 by passing through the opening 6a.
[0032] Figure 3 illustrates a second embodiment of the diffuser means 12. In said embodiment
the diffuser means 12 comprise a nozzle 17 configured to define a jet of diffused
fluid (also called mist or fog) configured to spray a large area of the outer surface
of the casing 6. Said configuration provides a screen of fluid for thermal protection
capable of confining the energy storage means 4 involved from the rest of the vehicle
1.
[0033] According to a further embodiment, not illustrated and usable on a casing 6 provided
with a meltable element 15, the diffuser means 12 can comprise a variable jet nozzle
configured to vary the shape of the jet from closed, to full to a fog jet.
[0034] For example, said nozzle is a motorized nozzle that can comprise a lever mechanism,
operated by a specialized actuator, configured to vary the opening of the nozzle in
order to vary according to the types described above.
[0035] Advantageously, the vehicle 1 comprises temperature sensor means, not illustrated,
configured to detect the temperature of each of the energy storage means 4. In particular,
said sensors can be of any type and be placed in the immediate vicinity, for example
on the casing 6 or inside the battery packs 5.
[0036] The vehicle 1 comprises, furthermore, an electronic unit electrically connected to
the temperature sensor means and comprising processing means configured to process
the signal detected by the temperature sensor means and compare it with a threshold
temperature stored in the electronic unit. Preferably, said electronic unit can be
the ECU of the vehicle 1.
[0037] If said temperature is higher than said threshold, the driver of the vehicle 1 is
warned of the danger of fire due to overheating of the energy storage means 4, by
visual or acoustic signalling means such as, for example, a warning light and/or an
acoustic signal. In this way, the driver can alert the emergency vehicles and ask
for assistance.
[0038] The vehicle 1 can further comprise telecommunication means, not illustrated, electronically
connected to the electronic unit and configured to communicate with one or more known
emergency stations, for example the fire department, the need for fire rescue and
essential vehicle data stored in the electronic unit of the vehicle, such as the position
(for example GPS) of the same, the type of vehicle, the licence plate number, the
presence of the fire extinguishing system 10 according to the present invention, etc.
In this way, if there is an overheating condition of the energy storage means 4, emergency
assistance is automatically requested.
[0039] Advantageously, if a nozzle of the variable jet type as described above is present,
the control of the actuator means can be carried out by the aforementioned electronic
unit or remotely by short-range remote control means, for example WiFi.
[0040] Said remote control means can comprise a remote control, provided on the vehicle
and usable by the driver or integrated by way of an app that can be downloaded on
any smartphone.
[0041] The operation of the vehicle 1 provided with a fire extinguishing system 10 as described
above is as follows.
[0042] If the electronic unit detects that the temperature of the energy storage means 4
exceeds the predetermined threshold, it will generate an overheating warning signal
to the driver of the vehicle 1 and, if foreseen, it will send an intervention request
signal to the nearest emergency station.
[0043] Whenever possible, the rescuers will be able to connect their pipes directly into
the openings of the hydraulic interfaces 11 so as to insert the fluid into the circuit
13. Inside the latter, the fluid will rise to the roof 2c and will be conveyed to
each diffuser means 12.
[0044] The casing 6 is provided with a meltable element 15 and the jet provided by the nozzle
16 will be direct and therefore will be sent directly to the battery pack 5, flooding
the same.
[0045] In the event that a casing 6 is provided which is totally isolated from the external
environment, the jet provided by the nozzle 17 will be spread over a large portion
of the casing 6 itself, thus directly cooling the battery pack on the inside thereof.
[0046] Obviously, the operation is similar when referring to pressurized gas tanks or if
the energy storage means 4 are not housed on the roof but in other inaccessible parts
of the vehicle 1.
[0047] If a variable flow nozzle is provided, the electronic unit or remotely the driver
of the vehicle 1 or a rescuer can adjust the shape of the jet of the diffuser means
12 according to the type of overheating/fire present in the energy storage means 4.
[0048] From the foregoing, the advantages of a vehicle 1 provided with a fire extinguishing
system 10 according to the invention are evident.
[0049] Thanks to the fire extinguishing system 10 it is possible to cool/extinguish a possible
ignition of fire relating to the energy storage means 4, thus avoiding an explosion
or the spreading of phenomena such as thermal runaway.
[0050] In particular, thanks to the fire extinguishing system 10 described, the driver and/or
the rescuers can be promptly notified in order to act as soon as possible.
[0051] Furthermore, rescuers are greatly facilitated because they can act at human height
to insert the fire extinguishing fluid that will reach the energy storage means 4,
even if placed at heights that are difficult to reach or inside panels of the vehicle
1.
[0052] The use of nozzles 16, 17 of different types makes it possible to obtain a versatile
fire extinguishing system 10 which can be used on energy storage means 4 provided
with closed casings or provided with a fire extinguishing access, such as that by
way of the described meltable element.
[0053] The use of heat and flame resistant pipes 14 allows the fire extinguishing fluid
to reach, even if it has already spread, various parts of the vehicle 1.
[0054] The use of a variable flow nozzle, possibly remotely controlled, allows to implement
an overheating/fire containment strategy optimized according to the specific situation
of the energy storage vehicles 4 in total safety.
[0055] Finally, it is clear that modifications and variations can be made to the vehicle
1 provided with a fire extinguishing system 10 according to the present invention,
which, however, do not depart from the scope defined by the claims.
[0056] As already mentioned, the energy storage means 4 can be of various types (electric
or explosive fluid) and can be enclosed in casings of different shape and position
in the vehicle 1.
[0057] Furthermore, the number of hydraulic interfaces, of energy storage means 4 and the
type of the hydraulic circuit 13 can vary as a result of the type of vehicle 1.
[0058] Finally, it is clear that the nozzles 16, 17 can be used in combination with one
another.
