Definitions
- TITLE THERMAL REGULATION DEVICE FOR COOLING AN ELECTRIC ENERGY STORAGE ORGAN
- the present invention relates to the field of thermal regulation devices and more particularly to the means implemented to regulate the temperature of electrical energy storage devices fitted to vehicles.
- the battery packs When the vehicle is operating, the battery packs can release a significant amount of heat and therefore be subject to temperature increases which in certain cases can cause them to be damaged or even destroyed. Consequently, their cooling is essential in order to keep them in good condition and thus ensure the reliability, autonomy and performance of the vehicle. Furthermore, the operation of the battery packs may be less efficient in the event of low temperatures, the electrical or electronic components equipping these battery packs then needing a time to warm up before operating at full efficiency.
- one or more thermal regulation devices intended to regulate the temperature of the battery packs are implemented to ensure the heating and/or cooling functions of the electrical or electronic components inside these battery packs and thus optimize the operation of the different components.
- thermal regulation devices are generally traversed by a thermal regulation fluid which can, depending on the needs, either absorb the heat emitted by each battery pack in order to cool it, or provide heat if the temperature of the battery pack is insufficient for its purpose. good operation.
- the thermal regulation devices can consist, for example, of a flat plate on which a stamped plate is affixed so as to form, between the flat plate and reliefs formed in the stamped plate, channels intended to be traversed by the thermal regulation fluid.
- This type of thermal regulation device generally extends over the entire surface formed by the corresponding battery pack, and the plate is arranged in the battery pack so that each of the storage cells can be positioned against the plate, so that the thermal regulation fluid circulating in the channels of the thermal regulation device is able to exchange calories with all of the electrical energy storage cells.
- the electrical energy storage cells of the same battery pack can be distributed over two stages of this battery pack, so as to optimize the space required for the installation of the battery pack within the vehicle it equips.
- thermoregulatory properties of the thermal regulation fluid are reduced if this cooling fluid circulates within the thermal regulation device so that it cools the electrical energy storage cells arranged on the first stage before cooling. the electrical energy storage cells arranged on the first floor, or vice versa. It is understood that such circulation of the thermal regulation fluid, to successively cool the two stages, would result in excessive heating of the thermal regulation fluid which would reduce its thermoregulatory properties at the moment when it must regulate the temperature of the energy storage cells. electric arranged on the second floor.
- the present invention aims to obviate this drawback by proposing a thermal regulation device which makes it possible to cool a first stage and a second stage of the same battery pack via a single closed cooling fluid circuit, which allows the circulation of the thermal regulation fluid within the first stage without this fluid being assigned to the cooling of the storage cells electrical energy of this first stage, thus allowing optimal cooling of the electrical energy storage cells of the second stage.
- the main object of the present invention is thus a thermal regulation device for cooling an energy storage member by a cooling fluid, comprising a first stage configured to be in contact with a first portion of the storage member. energy storage and a second stage configured to be in contact with a second portion of the energy storage member, the second stage being at least partly offset relative to the first stage in a vertical stacking direction, the first stage comprising a first support plate and a first distribution plate, the first support plate having a first face intended to be in contact with the energy storage member and a second face opposite this first face, the first distribution plate being in contact with this second face and being locally deformed so as to delimit circulation channels of the cooling fluid.
- the thermal regulation device comprises at least one additional plate positioned against the first face of the first support plate and delimiting at least one cooling fluid circulation conduit, the first stage and the second stage being in communication fluidic via the additional plate and a connection means.
- the thermal regulation device is intended to cool an energy storage member, for example a battery pack of a motor vehicle.
- an energy storage member comprises electrical energy storage cells, which here constitute a first portion and a second portion of the energy storage member. These two portions are respectively arranged, within the thermal regulation device, on a first thermal regulation stage and a second thermal regulation stage which are in fluid communication; we mean here that the first stage and the second stage are crossed by the same cooling fluid.
- first and second floors are here offset in a vertical stacking direction, the second floor being superimposed on the first floor in this direction.
- This solution may be preferred when the tubes cannot be placed inside the casing, in order to facilitate peripheral sealing between the support plate and the structural frame.
- FIG. 7 illustrates, schematically, a connection means of the thermal regulation device of Figure 3;
- FIG. 8 illustrates, schematically, the connection means of Figure 7 in a sectional view
- FIG. 9 illustrates, schematically, a means of connecting the thermal regulation device of Figure 4 in a perspective view.
- cooling fluid can relate to any heat transfer, refrigerant, thermal regulation, dielectric or two-phase fluid, as long as this fluid, liquid or gas, has the effect of cooling or heating electrical energy storage devices.
- FIGS i and 2 thus illustrate, schematically, a thermal regulation device 1 according to the invention according to a first embodiment, respectively in a top view and a bottom view.
- the thermal regulation device 1 extends mainly in a direction of extension which corresponds to a longitudinal direction, from a first longitudinal end 2 to a second longitudinal end 4.
- the thermal regulation device 1 has a first stage 10 and a second stage 12, on which the electrical energy storage cells 8 are distributed.
- the first stage 10 and the second stage 12 are superimposed in a vertical direction stacking E.
- the second floor 12 is arranged above the first floor 10 in this vertical stacking direction E.
- the second stage 12 has dimensions smaller than the first stage 10, so that it receives a smaller number of electrical energy storage cells 8.
- the second stage 12 is thus offset relative to the first stage 10 in the longitudinal direction, in the sense that unlike this first stage 10 it does not extend from the first longitudinal end 2 of the thermal regulation device 1 to its second longitudinal end 4.
- the thermal regulation of the first and second portions 14, 16 of the energy storage member 6, and more particularly their cooling, is ensured by the circulation of a cooling fluid within the thermal regulation device 1.
- the first stage 10 and the second stage 12 comprise for this purpose a support plate and a distribution plate each.
- the first stage 10 thus has a first support plate 18 and a first distribution plate 20, the second stage 12 comprising a second support plate 22 and a second distribution plate 24.
- At least part of the cooling fluid arriving in the thermal regulation device passes successively through a first connection end 36, the supply branch 301, the network of circulation channels for the cooling fluid 30 within the first stage 10, then through the evacuation branch 302 to be evacuated from the thermal regulation device via the second connection end 36.
- the first support plate 18 is planar.
- the additional plate 38 is placed on the first support plate 18 on its first face 26, that is to say opposite the first distribution plate 20. Like this first distribution plate 20, the additional plate 38 is locally deformed and has protuberances which define between them and the first face 26 of the first support plate 18 at least one circulation conduit for the cooling fluid 40.
- the additional plate 38 and the plates also forming the first stage, namely the first support plate 18 and the first distribution plate 20 can advantageously be made of the same material.
- Such the same material can, according to variants of the present invention, be aluminum or even a composite material, for example from plastic.
- Figures 1, 2, 5 and 6 thus correspond to a first embodiment, Figures 3, 7 and 8 to a second embodiment and finally Figures 4 and 9 to a third embodiment. These embodiments will now be described successively.
- the additional plate 38 has a first end 42 disposed in the vicinity of the first longitudinal end 2 of the thermal regulation device 1 and a second end 44 opposite this first end 42 and which is therefore in the vicinity of the second longitudinal end 4 of this thermal regulation device 1.
- the additional plate 38 is here substantially rectilinear from its first end 42 to its second end 44.
- the additional plate 38 comprises two cooling fluid circulation conduits 40. More particularly, the additional plate 38 comprises as these cooling fluid circulation conduits 40 a supply conduit in fluid of cooling 40A and a cooling fluid evacuation conduit 40B.
- the cooling fluid supply conduit 40A and the cooling fluid discharge conduit 40B have passage sections, that is to say surfaces measured in a plane perpendicular to the longitudinal direction, which are identical. 'one to the other and constant from one end to the other of the additional plate.
- Such a section of the cooling fluid circulation conduits 40 may advantageously be identical to a section of the cooling fluid circulation channels 30 formed within the first stage 10 and/or within the second stage 12.
- the cooling fluid circulates within these two cooling fluid supply and evacuation conduits 40A, 40B in two opposite directions.
- the first end 42 of the additional plate 38 is for this purpose arranged at the first longitudinal end 2 of the thermal regulation device 1 so that the cooling fluid supply conduit 40A faces, in the longitudinal direction, the connection end 36 which corresponds to a cooling fluid inlet within the thermal regulation device 1, and that the cooling fluid evacuation conduit 40B faces, in the longitudinal direction, the connection end 36 which is a cooling fluid outlet.
- the cooling fluid supply conduit 40A and the cooling fluid discharge conduit 40B are however not connected directly to the connection ends 36.
- the cooling fluid circulates between a end connection 36 and the cooling fluid supply conduit 40A via a first proximal diversion channel 46, diverging from the supply branch 301, and between the cooling fluid discharge conduit 40B and a connection end 36 via a second proximal diversion channel 46, converge towards the evacuation branch 302.
- proximal diversion channels 46 are, as for the circulation channels of the cooling fluid 30, formed by protuberances of the first distribution plate 20. They make it possible to form a parallel circuit in which circulates a portion of the cooling fluid diverted from the cooling fluid circulation channels 30 associated with the first stage 10.
- cooling fluid when cooling fluid is conveyed to the first distribution plate 20, a portion of this fluid is intended to circulate in the cooling fluid circulation channels 30 of the first stage 10 while another portion is intended to borrow these proximal diversion channels 36 to be conveyed to the additional plate 38 then to the second stage 12.
- the deflected portion of cooling fluid is reinjected into the cooling fluid circulation channels just before opening onto the connection tip 36 corresponding to the cooling fluid outlet tip.
- the first support plate 18 In order to allow the passage of cooling fluid through the first support plate 18 to pass from the circulation channels 30, between the second face 28 of the first support plate 18 and the first distribution plate 20, to a circulation conduit 40, between the first face 26 of the first support plate and the additional plate 38, and in order to allow the passage in the opposite direction of a circulation conduit to the circulation channels 30, the first support plate 18 has proximal orifices 48 which pass through it from side to side, that is to say opening out just as well on its first face 26 as on its second face 28.
- the second end 44 of the additional plate 38 which is that which is opposite the second longitudinal end 4 of the thermal regulation device 1, is arranged under the second stage 12.
- the additional plate 38 is fluidly connected to this second stage 12 via a connection means, particularly visible in Figures 2 and 5.
- a connection means here takes the form of two tubes 50 which are rigid and straight. These tubes 50 are vertical, that is to say substantially perpendicular to both the first stage 10 and the second stage 12.
- the tubes 50 are here arranged between the first support plate 18, and in particular the first face 26 of this first support plate, and the second support plate 22.
- These tubes 50 comprise a first tube 50A and a second tube 50B, the first tube 50A being arranged facing, in the longitudinal direction, the cooling fluid supply conduit 40A while the second tube 50B is arranged facing the cooling fluid evacuation conduit 40B in this direction longitudinal.
- the first tube 50A participates in supplying cooling fluid to the second stage, and here circulation channels provided between the second support plate 22 and the second distribution plate 24, from the cooling fluid circulating within the additional plate 38 and more particularly its cooling fluid supply conduit 40A, the second tube 50B being intended for the evacuation of the cooling fluid from the second stage 12 via the evacuation conduit of the 40B cooling fluid.
- the tubes 50 do not open directly into the additional plate 38.
- the cooling fluid to pass from the conduits delimited by the additional plate 38 to these tubes 50, thus borrows distal diversion channels 47, formed by protuberances of the first distribution plate 20 like the proximal diversion channels 46 arranged at the first end 42.
- a distal diversion channel 47 fluidly connects the conduit cooling fluid supply 40A and the first tube 50A and a distal bypass channel 47 fluidly connecting the cooling fluid discharge conduit 40B and the second tube 50B.
- each distal diversion channel 47 extends between a distal orifice 49, provided in the first support plate 18 between the second end 44 of the additional plate and a corresponding distal diversion channel, and an orifice of connection 51, provided in the first support plate 18 between the tube 50A, 50B and the corresponding distal diversion channel.
- the distal orifices 49 and the connection orifices 51 are shown in dotted lines in Figure 2, and the distal orifices are particularly visible in the sectional view of Figure 6.
- these distal orifices 49 and these connection orifices allow the passage of cooling fluid from one side to the other of the first support plate 18.
- the distal diversion channels 47 of the second end 44 are connected to the tubes 50 at the level of a projection 52 of the first support plate 18, in which the distal orifices are therefore made here.
- This projection 52 faces, in the vertical stacking direction E, a tongue 54 of the second support plate 22 which extends overhanging the second floor 12 to be in line with the projection 52. It is understood that the protrusion 37, the projection 52 and the tongue 54 make it possible to arrange the connection ends and the connection tubes on the periphery of the stages of the thermal regulation device so as not to reduce the heat exchange surface. with the energy storage member 6.
- the tongue 54 is pierced with two through holes, not illustrated in the figures, each allowing communication of cooling fluid channels of the second stage with one of the first and second tubes 50A, 50B.
- covers 58 are configured to guide the cooling fluid, with a function similar to that of the diversion channels 46, 47 of the first distribution plate 20, in that they each allow the passage of the cooling fluid from one face 26 to the other face 28 of the support plate 18 of the first stage 10 or from one surface 32 to the other surface 34 of the support plate 22 of the second floor 12.
- the cooling fluid to circulate within the second stage 12, enters the thermal regulation device 1 via the connection end 36 which corresponds to an inlet at the first longitudinal end 2 of the thermal regulation device 1.
- the cooling fluid circulates through the supply branch 301 then part of this cooling fluid circulates in one of the proximal diversion channels 46 and passes through one of the proximal orifices 48 of the first support plate 18 to open into the cooling fluid supply conduit 40A of the additional plate 38.
- the cooling fluid present in this supply conduit 40A can then circulate within the first stage 10 without being affected by the cooling of the electrical energy storage cells 8 arranged within this first stage 10, such cooling being carried out in parallel by the part of the cooling fluid not diverted into the proximal diversion channel previously mentioned and circulating within the cooling fluid circulation channels 30 delimited between the first support plate 18 and the first distribution plate 20.
- the cooling fluid present in this supply conduit 40A passes through one of the distal orifices 49 of the first support plate 18 so as to circulate in one of the distal diversion channels 47.
- This distal diversion channel 47 opens into the first tube 50A which participates in forming the means of connection between the first stage 10 and the second stage 12.
- the cooling fluid circulates as close as possible to the second portion 16 of the energy storage member 6, here between the second support plate 22 and the second distribution plate 24, in order to cool this second portion 16 of the energy storage member 6.
- the cooling fluid is then evacuated from the second stage via the second tube 50B, passing for this purpose through one of the through holes provided in the tongue 54.
- the cooling fluid circulates in the distal diversion channel 47, facing the second face 28 of the first support plate 18, up to the cooling fluid evacuation conduit 40B of the additional plate 38, which it joins via the other distal orifice 49 formed in the first support plate 18.
- the cooling fluid then circulates along the first face 26 of the first support plate 18, within the additional plate 38 from its second end 44 to its first end 42, then passes into the other proximal diversion channel 46 located at this first end 42 through the other proximal orifice 48. It can then reach the connection end 36 dedicated to the outlet and thus leave the thermal regulation device 1.
- the thermal regulation device i according to the second embodiment differs from the thermal regulation device i according to the first embodiment in that the connection means, in the form of tubes 50 fluidly connecting the first stage 10 and the second stage 12, is no longer arranged in the vicinity of the second longitudinal end 4 of the thermal regulation device 1.
- these tubes 50 are arranged among the electrical energy storage cells 8 between the first longitudinal end 2 and the second longitudinal end 4, within a central zone 60 of the thermal regulation device 1.
- This central zone 60 is not illustrated here equidistant from the first and second longitudinal ends 2, 4 but closer to the second longitudinal end 4, but it is understood that other arrangements of the tubes 50 between the first longitudinal end 2 and the second longitudinal end 4 are possible.
- the arrangement of the tubes 50 is conditioned by the longitudinal dimension of the second stage 12, these tubes 50 extending vertically and opening out in the vicinity of a longitudinal end of this second stage 12.
- the additional plate 38 has a dimension measured along the longitudinal direction which is reduced compared to that of the additional plate 38 of the first embodiment.
- This additional plate 38 extends here from the first longitudinal end 2, where its first end 42 is located, to the tubes 50, where its second end 44 is located.
- the tongue 54 is no longer cantilevered facing the projection 52 in the vertical stacking direction E; it is now oriented towards the first longitudinal end 2 of the thermal regulation device 1 so that it overlooks the additional plate 38 and more precisely its second end 44.
- the thermal regulation device 1 also differs from the first embodiment in that the tubes 50 are directly connected to the additional plate 38.
- the tubes 50 are arranged between the second stage 2 and this additional plate 38, as is particularly visible in Figures 7 and 8.
- the tubes 50 open into the additional plate 38 via perforations 62 made in this additional plate 38.
- the additional plate 38 has more precisely a perforation 62 made on its cooling fluid supply conduit 40A and a perforation 62 made on its cooling fluid evacuation conduit 40B, as illustrated in Figure 8.
- the perforation 62 arranged on the cooling fluid supply conduit 40A is connected to the first tube 50A, while the perforation 62 arranged on the cooling fluid evacuation conduit 40B is connected to the second tube 50B.
- the cooling fluid circulates directly from the circulation conduits 40 formed in the additional plate 38 to the tubes of the connection means 50 without needing to pass through the first support plate 18 to circulate in a channel of derivation.
- the distal orifices and distal diversion channels of the first embodiment are thus absent from the thermal regulation device according to the second embodiment. With this exception, the circulation of the cooling fluid within the thermal regulation device, from one connection end to the other with a portion of the cooling fluid diverted through the additional plate to supply the second stage, remains the same than that described for the first embodiment.
- the thermal regulation device 1 comprises a first additional plate 38A and a second additional plate 38B.
- These first and second additional plates 38A, 38B each extend around the periphery of the first support plate 18 and no longer centrally as was the case in the first two embodiments.
- the first additional plate 38A and second additional plate 38B are symmetrical along the longitudinal-vertical plane which divides the thermal regulation device 1 into two substantially equal parts.
- the additional plates 38A, 38B of the third embodiment only comprise a single cooling fluid circulation conduit 40.
- the first additional plate 38A delimits a supply conduit in fluid cooling 40A while the second additional plate 38B delimits a cooling fluid evacuation conduit 40B.
- the first additional plate 38A has the role of conveying the cooling fluid to the second stage 12, the second additional plate 38B being dedicated to its evacuation once it has cooled the energy storage cells electric 8 arranged on this second floor 12.
- Each of the additional plates 38A, 38B thus not rectilinear as for the first two embodiments, but they have bends at substantially right angles so as to follow the peripheries of the first support plate 18 which is rectangular and in particular its corners.
- Each of the additional plates 38A, 38B thus comprises a first portion extending along the first longitudinal end 2 of the thermal regulation device 1, a second portion extending along the second longitudinal end 4, and a third portion connecting these first and second portions and extending in the longitudinal direction.
- connection means is arranged at the second longitudinal end 4 of the thermal regulation device 1 and the tubes 50 which constitute it are arranged opposite the first and second additional plates 38A, 38B, with the first tube 50A facing the first additional plate 38A and the second tube 50B facing the second additional plate 38B.
- the first tube 50A and the second tube 50B each open into a distal diversion channel 47 allowing them to be fluidly connected respectively to the first additional plate 38A and to the second additional plate 38B.
- the present invention thus proposes a thermal regulation device capable of cooling a first stage and a second stage of the same energy storage member with the same closed circuit of cooling fluid, the presence of an additional plate attached to a front of the first floor making it possible to divert part of the cooling fluid and direct it towards the second stage without its temperature being adversely modified by heat exchange with cells of an energy storage member during its circulation along the first floor.
- the present invention cannot, however, be limited to the means and configurations described and illustrated here and it also extends to any equivalent means and configuration as well as to any technically effective combination of such means.
