Definitions
- the present invention provides a simple way to considerably improve the flow rate of LPG cylinders, it consists in increasing very weak convective exchanges under normal conditions by one or more fans, for example of the helical type, placed so as to create a air flow along the bottom of the bottles and the bottom of the bottles.
- the invention is defined in claim 1. Such a provision has the following advantages:
- the bottle or bottles are inside a fairing open at the lower part and provided with a series of openings at its upper part to allow the establishment of the air flow.
- a partition can be provided between each bottle.
- the bottles rest on supports providing free passages for air (rods or profiled bars, for example).
- a sufficient distance: 10 to 20 cm is preferably provided between the upper part of the fans and the plane on which the bottles rest, so that the air flow is established in the best conditions. It may be advantageous to slightly tilt (5 to 30 °) the axes of the fans with respect to the long axis of the bottle so that the air flow exchanges heat as much as possible with the walls of the latter.
- the fan can be mounted on a branch circuit, energized by switching on the engine circuit ignition key. The fan turns on as soon as the engine of the motor vehicle is turned.
- the fan is mounted on a branch circuit powered up by operating a switch specific to this branch circuit.
- the fan is supplied at the discretion of the user.
- a light and / or sound indicator is preferably provided to warn the user that the fan is operating.
- the fan is mounted on a branch circuit but energized by a pressure switch capable of determining the pressure prevailing in the bottle and closing the switch as soon as the pressure drops below a threshold given. The fan is thus used at best. Also in this case, provision is preferably made for an indicator light and / or sound which warns that the fan is operating.
- Figure 1 is a perspective view with cutaway of a device for supplying liquefied petroleum gas according to the invention
- Figure 2 is a schematic sectional view of a first variant
- Figure 3 is a schematic sectional view of a third variant
- Figures 4 to 7 are plan views illustrating four other variants
- Figure 8 is a diagram of an electrical circuit of a motor vehicle according to the invention
- Figures 9 and 10 are electrical diagrams of two variants of two electrical circuits of a motor vehicle according to the invention.
- the device for supplying liquefied petroleum gas shown in FIG. 1 comprises two bottles 1 of liquefied petroleum gas. Funds
- centrifugal fans 6 are mounted in staggered rows below the bars 3, at a vertical distance of 15 cm from them. The fans cause forced convection of the air surrounding the bottom 2 of the bottles 1 and the air surrounding the bottom of the bottles 1, an air flow being created between the air drawn in from the bottom of the fairing 4 and the exhaust air from the vents 5.
- FIG. 2 there is provided a single fan 6 whose axis coincides with the axis XX 'of the bottle 1. There is shown by arrows the direction of the air discharged by the fan 6, as well as the case if necessary, the rebound of the discharged air on the bottom 2 of the bottle 1.
- two fans 6 are provided for a single bottle 1, these fans are arranged on either side of the bottle, and their axis YY 'is inclined with respect to the axis XX' of the bottle at an angle of 15 °.
- Figure 4 there are provided two bottles and below these three fans, two end fans 6 located half in below the bottle and outside it and a central fan 6 arranged exactly between the two bottles 1, the latter partially overlapping it.
- two bottles 1 and two fans are provided
- FIG. 6 which are arranged respectively as in FIG. 2.
- two fans 6 are provided per bottle 1, the fans 6 being arranged diametrically opposite with respect to the axis of each bottle 1. Again, each bottle partly overlaps the fans 6 associated with it.
- FIG. 8 illustrates an electrical circuit of a motor vehicle comprising a battery 7 connected by a line 8 to the motor 9 by means of a switch 10 to ignition key 11.
- the motor 12 of an electric fan 6 is mounted in parallel with the motor 9. When the user turns the ignition key 11 to start the motor 9, he energizes the fan 12.
- FIG 9 there is provided a particular switch 13 for the fan motor 14. It is also mounted in parallel with an indicator 15 and an emitter 16 of an audible signal which alerts the user that the switch 13 is closed.
