Definitions
- the present invention relates to the field of thermal batteries and more specifically that of thermal batteries comprising a phase change material.
- Thermal batteries are generally used for heating the passenger compartment, in particular in electric and hybrid vehicles or for preheating a heat transfer fluid in a thermal management circuit.
- the thermal batteries can also be used for preheating the engine oil or the automatic gearbox oil of internal combustion engine vehicles.
- a thermal battery with a phase change material generally comprises an enclosure forming a reservoir inside which is placed the phase change material generally in encapsulated form, in particular in the form of tubes forming a bundle.
- the performance of the thermal battery is dependent on the amount of phase change material that it can contain, ie the number of tubes present in the beam, but also the contact surface between the fluid passing through the thermal battery and said tubes. .
- the tubes must therefore be kept at a distance from each other so that the fluid passing through the thermal battery can circulate. However, the tubes must also be quite close to each other in order to integrate the most phase change material within the thermal battery for the latter to be effective.
- An object of the present invention is therefore to at least partially overcome the disadvantages of the prior art and to provide an improved thermal battery.
- the present invention therefore relates to a thermal battery comprising an enclosure comprising an inlet and a fluid outlet and comprising, within it, a bundle comprising tubes of encapsulated phase-change material, the bundle being formed by a stack of tubesheets, webs having tubes arranged parallel to each other and being connected by webs of spacers and holding, said webs having on at least one of their faces individual housing, separated from each other by a side wall, each housing being able to receive a tube.
- the bars allow a great modularity in the design of the thermal batteries, but also allow a reduction of the production costs.
- the use of such strips allows a good maintenance and good organization of the tubes together so as to form a beam and limiting the pressure losses of the fluid passing through.
- the spacing between the tubes within a sheet is defined by the width of the side wall between two housings.
- the housing has a shape complementary to the shape of the tubes and an insertion opening smaller than the diameter of the tubes so that said tubes can be clipped into the housing.
- the successive webs of strips are staggered on planes parallel to each other and perpendicular to the tubes.
- the strips between two successive layers do not overlap and allow the fluid to flow between the tubes without there being too much pressure loss.
- the successive webs of webs are grouped in two parallel planes and separated by a distance at least greater than the width of the webs.
- the beam is contained in a frame.
- the frame comprises flanges surrounding the bundle and external struts connecting said flanges.
- the flanges comprise grooves in which are inserted bars.
- the plies comprise internal spacers between the bars.
- the layers are flat.
- the beam is cylindrical and the plies are curved and concentric.
- the bars comprise housings on two of their opposite faces, so as to maintain two superimposed layers, the spacing between said layers being defined by the thickness of the wall of said strips separating the housings located on both sides of the bars.
- the housing on one side of the bars and the housing on the other side of said bars are arranged in staggered rows.
- the bars comprise housings on only one of their faces.
- the tubes of two successive layers are staggered, the tubes of the upper layer resting on the side wall of the strip of the lower layer, the spacing between the tubes of said layers being defined by the height of said side wall.

- Figure 11 shows a schematic cross-sectional representation of a stack of webs according to an alternative embodiment.
- FIGS 1 and 2 show a schematic representation of a thermal battery 1 having an enclosure 2 in which flows a fluid between an inlet 2a and a fluid outlet 2b.
- the thermal battery 1 comprises within the chamber 2 a beam 3 composed of 3 'tubes of phase change material.
- the tubes 3 'of the bundle 3 are arranged parallel to each other.
- Beam 3 can for example be inserted into the chamber 2 through an opening 2c. Said opening 2c is closed after insertion of the beam 3 by a cover 2d.
- the beam 3 is arranged parallel to the fluid flow flow inside the chamber 2.
- the tubes 3 'of phase change material comprise a tubular wall, preferably made of plastic, for example polycarbonate, at the inside which is disposed a phase change material.
- the tubular wall is sealed to the ends of the tubes 3 '.
- the bundle 3 is formed by a stack of layers 4 of tubes 3 '.
- These plies 4 comprise tubes 3 'placed parallel to each other and connected by spacer bars 5 and holding.
- the bars 5 may be rectilinear as shown in Figure 3.
- the sheets 4 are then flat and can be stacked on top of each other.
- the length L of the webs 5 of a web 4 determines the width thereof and it is thus possible to vary the shape of the beam 3 by modulating the length L of the webs 5 and thus the width of the webs 4 between them.
- An example of a beam 3 of generally cylindrical shape is thus illustrated in Figures 1 to 5.
- Other forms of the beam 3, for example parallelepipedal, are however quite possible and imaginable.
- the bars 5 are illustrated in greater detail in FIGS. 6 to 7b.
- Said strips 5 comprise on at least one of their faces, individual housings 50, separated from each other by a side wall 51.
- the housings 50 are intended to each receive a tube 3 'so as to form the sheet 4.
- the spacing between the tubes 3 'within a sheet 4 is defined in particular by the width Lp of the side wall 51 between two housings 50.
- the housings 50 may have a shape complementary to the shape of said tubes 3' and have an insertion opening 52 less than the diameter of the tubes 3 'so that said tubes 3' can be clipped into the housings 50.
- the lateral walls 51 are then elastic and can deform and move away from each other to allow the insertion of a tube 3 'in the housing 50. Once the tube 3' inserted, the side walls 51 return to their initial position and partially enclose the tube 3 'to block it.
- the bars 5 comprise closed housings 50 in which the tubes 3 'are threaded.
- the bars 5 may, for example, be overmolded around the tubes 3 'so as to form the plies 4.
- the strips 5 are preferably made of plastic and may be made of a long ribbon which will be cut to the desired length L as a function of the shape and size of the thermal battery 1.
- the bars 5 thus allow a great modularity in the design of thermal batteries, but also allow a reduction in production costs.
- the use of such strips 5 allows good maintenance and good organization of the tubes 3 'between them so as to form a beam 3 and limiting the pressure losses of the fluid passing through.
- the bars 5 may comprise housing 50 on two of their opposite faces.
- a bar 5 can thus hold the tubes 3 'of two superposed sheets 4, one on each of its faces.
- the spacing between the plies 4 is then defined by the thickness E of the wall of said strips 5 separating said housings 50 located on either side of the bars 5.
- the housings 50 on one side of the bars 5 and the housings 50 on the other side of said bars 5 are arranged in staggered rows.
- staggered arrangement in the present case and in the remainder of the application, is meant a repetitive arrangement of elements, line by line, where every other line is offset from a certain portion, in particular by half of an element, with respect to the line that precedes or follows it.
- the strips 5 of successive layers 4 are preferably arranged in staggered rows parallel to each other and perpendicular to the tubes 3 ', as shown in Figure 7b.
- the bars 5 between two successive layers 4 do not overlap and allow the fluid, whose flow is represented by two black arrows, to flow between the tubes 3 'without there being too much pressure loss.
- the webs 5 of successive webs 4 can be grouped in two parallel planes and separated by a distance D at least greater than the width Lb of the webs 5 so that the webs 5 are not contiguous and thus allow the flow of fluid as shown in Figure 7b.
- Said bars 5 then form a holding unit 6.
- the beam 3 may comprise several holding units 6. These holding assemblies 6 are also visible in FIGS. 2 and 5.
- the bars are also visible in FIGS. 8 to 10b.
- a bar 5 can hold the tubes 3 'only of a single sheet 4.
- the tubes 3' of two successive sheets 4 are arranged in staggered rows as shown in Figure 10a, to facilitate the flow of fluid and also to optimize the number of tubes 3 '.
- the tubes 3 'of the upper ply 4 can thus rest on the side wall 51 of the bar 5 of the lower ply 4.
- the spacing between the tubes 3 'of said plies 4 is then defined by the height Hp of said side wall 51 corresponding to the distance between the base and the end of said side wall 51.
- the bars 5 between two successive layers 4 do not overlap and allow the fluid, whose flow is represented by two black arrows, to flow between the tubes 3 'without there being too much pressure loss.
- the bars 5 can be grouped in two parallel planes and separated by a distance D at least greater than the width Lb of the bars 5 so that the bars 5 are not contiguous and thus allow fluid circulation as shown in Figure 7b. Said bars 5 then form a holding unit 6.
- the beam 3 may comprise several holding units 6. These holding assemblies 6 are also visible in FIGS. 2 and 5.
- the bundle 3 comprises at least one holding assembly 6 at each of its ends and at least one intermediate holding assembly 6 between said ends. This allows a constant spacing of the plies 4 between them and therefore a constant spacing of the tubes 3 'over the entire length of the beam 3.
- the beam 3 comprises a total of four sets 6 of maintenance.
- the beam 3 may also comprise, within the plies 4, inner struts 41, visible in FIGS. 4 and 5.
- These internal struts 41 may more particularly be solid and rigid tubes made of plastic or metal material and which may in particular take the place of a tube 3 'in a sheet 4 and thus clipper in the housing 50 of the bars 5.
- These internal spacers 41 stiffen the plies 4 and also to maintain the bars
- the internal struts 41 make it possible to maintain the cohesion of the holding assemblies 6 and to maintain the spacing between them.
- the internal struts 41 may comprise grooves 42, corresponding to a narrowing of the cross section. the internal spacer 41. These grooves 42 are inserted into the housings 50 of the bars 5. As a result, all translation movements of said bars 5 along the tubes 3 'and relative to each other are blocked.
- the beam 3 is preferably contained in a frame 7 as shown in FIGS. 1, 2 4 and 5. This frame 7 makes it possible in particular to consolidate the shaping of the beam 3 as well as its holding. In addition, the frame 7 makes it possible to provide a certain rigidity to the beam 3.
- the frame 7 may in particular comprise flanges 70 surrounding the beam 3 transversely and external struts 71 connecting said flanges 70.
- the flanges 70 and the external struts 71 can be made of metal and / or plastic material.
- the flanges 70 may also comprise grooves 701 in which the bars 5 are inserted. These grooves 701 more particularly allow a connection of said bars 5 with the frame 7 in order to keep said bars 5 in place in position. more because they can be clipped to the tubes 3 'and in addition to the possible presence of internal spacers 41. When the plies 4 are flat, it is the ends of the various bars 5 which are inserted into the grooves 701. The flanges 70 may then comprise at least two parallel grooves 701 and be positioned at the level of the holding assemblies 6.
- the half-beams can for example be assembled and fixed together for example by means of male / female fasteners present at the flanges 70.
- the plies 4 can be curved and stacked concentrically so as to form a cylindrical beam 3, as shown in FIG. 11.
- the production of a bundle 3 by stacking 4 flat sheets is preferable.
- the use of a frame 7 makes it possible in particular to maintain the curvature of said plies 4 as well as the cylindrical shape of the bundle 3.
- the bars 5 do not include housing 50 only on one of their faces, it is the back, that is to say the portion not bearing housing 50, the bars 5 of the outer ply 4 which is inserted into the grooves 701 of the flanges 70.
