Definitions

  • the present invention concerns a tank arrangement for storing cryogenic fluid.
  • the present invention finds its preferred, although not exclusive, application in work vehicles such as agricultural vehicle. Reference will be made to this application by way of example below.
  • LNG natural liquified gas
  • CNG compressed natural gas
  • the aforementioned fluids need to be maintained at very low temperatures in order to allow to store sufficient mass of fluid to guarantee a sufficient operativity of the vehicle.
  • the inner and outer tanks have usually a cylindrical shape and dome-shaped terminal portions, such as a "pill". Even if such portion allows to support high pressures at the low temperatures of the cryogenic fluid contained therein, it is however a bulky solution.
  • An aim of the present invention is to satisfy the above-mentioned needs in a cost-effective and optimized manner.
  • FIG. 1 shows a tank arrangement 1 for a vehicle (not shown) such as an agricultural vehicle and configured to store a cryogenic fluid that could be used to feed a power generator, such as an internal combustion engine or a fuel cell module of the vehicle.
  • a power generator such as an internal combustion engine or a fuel cell module of the vehicle.
  • the tank arrangement 1 comprises a first, outer, tank 2 and a second, inner, tank 3.
  • the first tank 2 is dimensioned to define a space 4' configured to house the second tank 3. This latter is configured to define a space 4" configured to house a cryogenic fluid.
  • each tank 2, 3 is realized in more pieces that are connectable together to the define the aforementioned spaces.
  • first tank Only portions of the first tank are visible and described, bearing in mind that the second tank 3 is similar but has smaller dimension in order to be contained within space 4'.
  • connection of the second tank 3 to the first tank 2 may be realized in different manner and will be not described in detail for sake of brevity.
  • Each tank 2, 3 comprises a pair of head portions 2' configured to be connected to an intermediate portion 2".
  • the head portions 2' are connected to the intermediate portion 2'' at respective extremities along a longitudinal axis A direction.
  • the intermediate portion 2'' may be realized by rolling and has a length X along longitudinal direction that may be selected in order to vary the volume of spaces 4', 4".
  • Each tank 2, 3 has therefore a prismatic shape since the cross-section of the intermediate portion 2'' is constant along longitudinal axis A direction.
  • the head portions 2' have the same shape.
  • the cross-section of the intermediate portion 2'' and of the head portions 2' has a trilateral shape that may be contained within a scalene and obtuse-angle triangle.
  • cross-section comprises three sides 5, 6, 7 that are alternated by joint portions 8, 9, 10 that connected together two-by-two the three sides 5, 6, 7.
  • All the sides 5, 6, 7 have a curved shape and in detail a first side 5 has a greater curvature radius with respect to a second side 6 that has a greater curvature radius with respect to a third side 7.
  • the first side 5 has a high curvature radius thereby leading to a substantially flat shape.
  • the second and third sides are spaced along a transversal axis B and the first side 5 is placed substantially below the second and third sides 6, 7 with respect to a vertical axis C.
  • the longitudinal, transversal and vertical axis A, B, C are all perpendicular one with respect to the other.
  • a first joint portion 8 connects together the first and second sides 5, 6, a second joint portion 9 connects together the second and third sides 6, 7 and a third joint portion 10 connects together the third and first sides 7, 5.
  • the second and the third joint portions 9, 10 have substantially the same curvature radius that is smaller with respect to the curvature radius of the first joint portion 8.
  • the head portions 2' have not a constant cross section along longitudinal axis A.
  • first edge 11 of this latter that is coupled to the intermediate portion 2'' has the cross-section dimension with respect to this latter while a second edge 12 of the head portions 2', opposite to the first edge 11 has a smaller dimension, i.e. it may be contained within the perimeter of first edge 11.
  • the second edge 12 is the perimeter of a flat wall having the above described cross-section.
  • the reduction is obtained by non-linear reduction via curved portions 13', 13'' that connects together first and second edges 11, 12.
  • front curved portions 13' are not equal to the rear curved portion 13'' along transversal axis B, therefore in the trilateral shape of the second edge 12 ratio between second and third sides and the first side is smaller than in the first edge 11.
  • the front curved portion 13' have a smaller curvature radius with respect to the rear curved portions 13".
  • the proposed shape of the tank arrangement 1 allows the storing of the cryogenic fluid in the space 4". If, for any reason, it is necessary to have a greater tank arrangement 1, it is sufficient to substituted the intermediate portions of the first and of the second tank thereby obtaining a greater volume without changing the head portions.
  • the volume of the space storing the cryogenic fluid is high while the encumbrance of the tank arrangement is reduced.
  • the proposed shape allows to store the cryogenic fluid with a smaller extension along longitudinal axis and with a shape that provides a facilitated arrangement on the vehicle.
  • the proposed shape decreases the stresses to the overall structure of the tank arrangement thereby allowing to store high pressure cryogenic fluid, e.g. about 5 bars.
  • volume of cryogenic fluid storing space may be varied easily by substituting only the intermediate portion and maintaining the same head portion. This provides a great versatility for modification on vehicle and scale economy in the manufacturing of the tank arrangement.
  • the proposed number of portions and shape and number of sides of the cross-section of such portions may be varied within the limits defined by the below claims.
