Definitions

  • the present invention relates to an assembly for combatting fire by means of supplying a radical-neutralizing aerosol.
  • the invention also relates to a cabinet for containing electronic equipment provided with mating means for co-action with coupling means of electronic equipment.
  • the invention also relates to a method for fire protection of a cabinet for containing electronic equipment.
  • Aerosol fire extinguisher comprises a holder in which is arranged, among other things, a starting material (solid extinguishing material) which, after activation, is converted into an aerosol.
  • a starting material solid extinguishing material
  • the aerosol which is generated combats fire (other than by making use of conventional methods based on smothering or based on cooling) by ending the combustion reaction on a molecular basis.
  • the free radicals present in the fire are herein bonded by the generated aerosol without affecting the local oxygen content.
  • the invention has for its object, while retaining the advantages of the prior art, to provide an assembly for combatting fire which can be arranged in simple manner and inexpensively in a cabinet for containing electronic equipment.
  • the invention provides for this purpose an assembly for combatting fire by means of supplying a radical-neutralizing aerosol, comprising: at least one holder with a starting material for generating the aerosol, activating means which co-act with the starting material and with which a conversion of the starting material into the aerosol can be initiated, and a carrier with which the holder with starting material and the activating means are assembled, wherein the carrier is provided with coupling means which are adapted to co-act with mating means forming part of a cabinet for mounting of electronic equipment, which mating means are adapted for mounting electronic equipment.
  • the holder and the activating means can optionally be accommodated here in a single housing.
  • the dimensions of the coupling means and the mating means are preferably standardized; it is for instance possible here to envisage the couplings such as are applied in standard patch cabinets of for instance 19 inches.
  • patch cabinets are usually applied for the purpose of containing for instance computer equipment, communication means and switch systems.
  • the great advantage of the present assembly is that, in very simple manner and at limited cost, it provides the option of arranging a fire protection in (and removing it from) cabinets accommodating electronic equipment. No specialist knowledge in the field of fire-fighting is required for this purpose. It is precisely in such an environment that there is an increased fire hazard.
  • the fire protection for arranging moreover has the advantage that no special provisions need be arranged (for instance connections to public utilities are unnecessary).
  • the proposed fire protection takes up only a limited space but still has a large extinguishing capacity, wherein it is furthermore noted that the applied extinguishing agent causes no damage to the surrounding area when used (such as the equipment located in the cabinet).
  • the assembly according to the invention can moreover be embodied such that only very little maintenance and inspection is necessary (for instance an embodiment which is free of maintenance for 15 years).
  • the activating means comprise at least one sensor for fire detection.
  • a sensor can for instance consist of a fire alarm (smoke detector, temperature sensor and so on) generating an electric signal.
  • the electric signal generated by such a fire detector can be transmitted via feed wires to the activating means.
  • a fire detector generating an electric signal with a separate power supply (for instance a battery).
  • a separate power supply for instance a battery
  • Use can however also be made of other types of sensor, such as for instance a sensor in the form of a "thermo-cord”.
  • the holder with starting material can be provided with an exit opening for aerosol. When the activating means initiate the conversion of the starting material into the aerosol, there occurs a considerable increase in the volume of the material.
  • the aerosol will have to be guided in one or more desired directions in order to carry the aerosol to the source of the fire.
  • the aerosol can be employed optimally to combat the fire.
  • the carrier is formed by a housing in which an opening is arranged to which connects the exit opening for aerosol from the holder with starting material. The aerosol will hereby exit the housing at the position where the aerosol is desired.
  • the housing can for instance be embodied as a substantially block-shaped construction (for instance a flat box and/or in the form of a drawer construction). It is also possible to opt for the use of a construction in which cooling means connect to an exit opening for the aerosol, so that the aerosol will arrive at a lower temperature at the location where the extinguishing effect is desired. It is also possible for the carrier to be formed by a housing in which an opening is arranged to which the sensor for fire detection connects.
  • an opening for the sensor and a passage opening for aerosol are both placed on the underside of the carrier so as to thus combine a good detection with a good extinguishing action; heat and smoke will in any case tend to rise, while the large increase in volume of the starting material to aerosol makes it possible to also urge the aerosol in downward direction.
  • the carrier is preferably provided at least at two spaced-apart positions with coupling means, wherein it is desired that the coupling means protrude from opposite sides of the carrier.
  • the opening in the carrier onto which an exit opening connects for aerosol from the holder with starting material is located at a distance from the coupling means.
  • the activating means comprise an electronic control system.
  • a system can for instance be a time switch with which the operation of the assembly can be controlled, can comprise a delay in which a control measurement can for instance be performed after detection of a fire, and/or activating means can be arranged with which the assembly can be activated manually or remotely (optionally after detection of a fire).
  • the invention furthermore provides a cabinet for containing electronic equipment provided with mating means for co-action with coupling means of electronic equipment, wherein the cabinet is provided with an assembly for combatting fire by means of supplying a radical-neutralizing aerosol as described above, the coupling means of which assembly engage on the mating means of the cabinet.
  • a cabinet can also be incorporated a discharge opening through which aerosol is discharged after the extinguishing operation has been carried out (the aerosol flow can thus be properly controlled). If the coupling means and mating means are releasably connectable, the carrier can be readily disconnected, for instance for maintenance, repair, inspection or removal of the fire protection.
  • the invention further provides a method for fire protection of a cabinet for containing electronic equipment by placing in the cabinet an assembly for combatting fire by means of supplying an aerosol neutralizing the radicals as described above, by bringing about a connection between the coupling means of the assembly and the mating means forming part of the cabinet, which mating means are adapted for mounting electronic equipment.
  • This method also enables people having no expertise whatever in the field of fire protection to provide a cabinet for electronic equipment in reliable manner with protection.

  • figure IB is a bottom view of the assembly of figure 1A
  • figure 2 shows a perspective and cut-away view of an embodiment variant of an assembly for combatting fire according to the invention
  • figure 3 is a perspective view of a cabinet for containing electronic equipment according to the invention.
  • Figure 1 A shows a holder 1 for generating a radical-neutralizing aerosol. Also arranged in holder 1 are activating means, not visible in this figure, for initiating a reaction whereby the aerosol is obtained from a starting material arranged in holder 1.
  • the figure also shows a detector 2 with which fire can be detected (for instance a conventional smoke detector and/or heat sensor). Detector 2 is coupled by means of a signal line 3 to holder 1.
  • the conversion process in holder 1 can be set into action by means of actuation by detector 2.
  • Holder 1 and detector 2 are both assembled in a box-like housing 4. Housing 4 is provided on a front side 5 with indicator means 6 which are connected by means of a signal line 7 to detector 2.
  • the state of detector 2 for instance can be visually displayed with the indicator means.
  • Housing 4 is provided on two opposite sides with protruding coupling means 8 with which the whole unit of holder 1, detector 2 and housing 4 (designated as assembly 9) can be incorporated in simple manner into a standard switch cabinet. This will be further elucidated with reference to figure 3.
  • Figure IB shows the underside of the assembly 9 shown in figure 1A.
  • the underside of housing 4 is provided with two openings 10, 11.
  • a first opening 10 provided with a protective grid 12 connects to the detector 2 shown in figure 1 A and the second opening 11 connects to the holder 1 of figure 1 A.
  • Through openings 10, 11 both the detector 2 and holder 1 can communicate with the environment of assembly 9; detector 2 for monitoring ambient conditions and holder 1 for generating aerosol.
  • Figure 2 shows an assembly 13, a housing 14 of which comprises a control module 15 in addition to the holder 1 for generating a radical-neutralizing aerosol and the detector 2 with which fire can be detected.
  • Holder 1 and detector 2 are connected to control 15 by means of respective signal lines 16, 17.
  • Control 15 is further connected to indicator means 6 and an on/off switch 18.
  • Control 15 makes it possible to synchronize the operation of assembly 13 with diverse other equipment. It is for instance also possible to incorporate a time delay into the operation of assembly 13 (consider for instance the possibility of manual deactivation for a short period after a fire is detected).
  • FIG. 3 finally shows a switch cabinet 19, a door 20 of which is shown opened.
  • Anchored in cabinet 19 are two mounting profiles 21 on which diverse electronic equipment 22 is mounted.
  • the equipment 22 is also provided with mutual connections 23.
  • the equipment is coupled releasably to mounting profiles 21, which have standardized dimensions for this purpose.
  • An assembly 24 is also arranged at the top of cabinet 19, whereby cabinet 19 is protected against fire. Assembly 24 is coupled releasably to mounting profiles 21 in similar manner to the equipment 22. It is recommended that assembly 24 extends deeper into cabinet 19 than equipment 22 such that an exit opening for aerosol is also located in cabinet 19 at a position deeper than the rear sides of equipment 22; the aerosol will thus be able to spread relatively quickly in the (closed) cabinet 19.
