Description

Technical Field

[0001] The present invention relates to a device for regulating heat for a component. The present invention relates to a module comprising such a device for regulating heat for a component.

[0002] The invention also relates to a method for assembling such a thermal conditioning device. Background Art

[0003] It is currently known that electric, thermal or hybrid vehicles are equipped with electrical energy storage components for supplying power to various components of the vehicle. These electrical energy storage components are generally composed of electrical energy storage cells placed in a battery pack.

[0004] Automobile manufacturers are currently seeking to provide more powerful electric or hybrid vehicles with increased electrical autonomy. To this end, more and / or larger battery packs are being installed in these electric or hybrid vehicles. It is known that the entirety of these battery packs, or at least a portion thereof, is installed in the vehicle floor, essentially across the entire width of the vehicle.

[0005] It should be understood that when a vehicle is operating, battery packs can release significant amounts of heat and therefore experience elevated temperatures, which in some cases can damage or even destroy the battery packs. Therefore, they must be cooled to maintain optimal condition, thereby ensuring vehicle reliability, range, and performance levels. Furthermore, battery packs can operate less efficiently at low temperatures, and the electrical or electronic components that incorporate these battery packs then require time to warm up before operating at full capacity.

[0006] For this purpose, one or more thermal regulation devices are implemented, designed to regulate the temperature of the battery packs, in order to ensure heating and / or cooling functions of the electrical or electronic components inside these battery packs, thereby optimizing the operation of the various components.

[0007] These thermal conditioning devices are typically permeated with a heat transfer fluid which can absorb heat dissipated by each battery pack to cool the pack, or supply heat if the pack temperature is insufficient for normal operation.

[0008] The temperature of the heat transfer fluid of the osmotic heat regulating device changes when the heat transfer fluid is in thermal contact with the component.

[0009] When the heat transfer fluid reaches a low temperature in order to cool a component, it tends to cool the first component it encounters compared to the remaining components further downstream because the heat transfer fluid has not had time to be heated by the component.

[0010] The resulting temperature imbalance between the first component and the remaining components further downstream may result in suboptimal operation of the components, the operation of which is temperature sensitive. Summary of the Invention

[0011] The present invention aims to overcome this drawback and in particular to prevent imbalances in temperature between a first component and the remaining components further downstream.

[0012] The object of the present invention is therefore a device for thermal regulation of components whose operation is sensitive to temperature, wherein these components are in particular intended for energy storage and may be battery cells, in particular for vehicles, said device comprising:

[0013] - heat transfer fluid distribution channels,

[0014] - a deceleration chamber for decelerating the heat transfer fluid passing through the distribution channel, the deceleration chamber having a first fluid passage cross section, the first fluid passage cross section being larger than the second passage cross section of the distribution channel at a junction with the deceleration chamber upstream, and being larger than the third passage cross section of the distribution channel at a junction with the deceleration chamber downstream;

[0015] - heat transfer fluid flow branches, into which the heat transfer fluid from the distribution channels is distributed; and

[0016] - at least one placement area for receiving the component, the placement area facing the heat transfer fluid deceleration chamber, so that the component placed in the placement area can exchange heat with the heat transfer fluid.

[0017] Two regions are said to "face" each other when they overlap when viewed along an axis perpendicular to the regions.

[0018] According to the present invention, the heat transfer fluid passing through the deceleration cavity is decelerated. Reducing the velocity of the heat transfer fluid reduces the heat exchange, especially compared to the case where the heat transfer fluid is not decelerated in the absence of such a deceleration cavity.

[0019] When the heat transfer fluid reaches a low temperature, this has the effect of cooling the components located in the placement area facing the deceleration cavity to a lesser degree than would be the case without such a deceleration cavity. This prevents the components from being overcooled by the heat transfer fluid from the distribution channel.

[0020] Thus, the temperature imbalance between the first component encountered by the heat transfer fluid and the remaining components further downstream is reduced. As a result, all components can operate optimally because the temperature between the components is more uniform.

[0021] Thus, the distribution channel can be used to cool the components placed on top of it. As a result, a greater number of components can be placed on the thermal conditioning device overall. For a given size thermal conditioning device, this increases the energy storage capacity of the components and, therefore, the range of the vehicle powered by that energy.

[0022] Advantageously, the invention allows reducing temperature imbalances while promoting a reduction in pressure losses compared to channels without a deceleration cavity.

[0023] Furthermore, in battery pack applications, there are often significant constraints on the total available height (or available vertical space), which can limit channel height. One aspect of the present invention allows for increasing the distribution channel's cross-section without increasing the height. This improves fluid velocity and heat transfer from the cells, as the greater the increase in the distribution channel's cross-section, the greater the number of cells that can be contacted.

[0024] According to one aspect of the present invention, the heat transfer fluid circulation branch is connected to the deceleration cavity so that the heat transfer fluid having passed through the deceleration cavity is distributed in the heat transfer fluid circulation branch.

[0025] According to one aspect of the invention, the device includes a heat transfer fluid exhaust channel.

[0026] According to one aspect of the invention, the flow branch opens into a heat transfer fluid discharge channel.

[0027] According to one aspect of the present invention, the heat transfer fluid circulation branch includes at least one branch channel connected to the heat transfer fluid discharge channel.

[0028] According to one aspect of the present invention, the flow branch comprises at least one straight branch channel connected to the heat transfer fluid discharge channel.

[0029] According to one aspect of the present invention, the flow branch includes at least one serpentine branch channel connected to the heat transfer fluid discharge channel.

[0030] According to one aspect of the present invention, the flow branch comprises at least two straight branch channels, wherein each branch channel is connected to the heat transfer fluid discharge channel.

[0031] According to one aspect of the present invention, the branch channel is connected to the heat transfer fluid discharge channel.

[0032] According to one aspect of the invention, the thermal conditioning device comprises two plates, an upper plate and a lower plate.

[0033] According to one aspect of the invention, at least one of the plates comprises protrusions, in particular protrusions formed by stamping, which can form, for example, distribution channels, deceleration chambers and heat transfer fluid circulation branches, as well as heat transfer fluid discharge channels.

[0034] According to one aspect of the present invention, one of the facing components in the panels is defined as an upper panel and includes at least one placement area, while the other panel, one surface of which faces the surface of the upper panel, is defined as a lower panel.

[0035] According to one aspect of the invention, the device comprises two plates, an upper plate and a lower plate, the upper plate being the plate facing the component and comprising the placement area, and the lower plate being one of the plates having a face opposite to the face of the upper plate.

[0036] According to one aspect of the invention, the placement area is located on one of the plates of the thermal conditioning device.

[0037] According to one aspect of the invention, each branch comprises a tray, in particular a flat tray, comprising a plurality of placement areas for receiving components.

[0038] According to one aspect of the invention, the dispensing channel passes underneath the tray.

[0039] According to one aspect of the invention, the discharge channel passes from under the tray.

[0040] According to one aspect of the invention, the distribution channel is connected to the heat transfer fluid inlet.

[0041] According to one aspect of the invention, the exhaust channel is connected to the heat transfer fluid outlet.

[0042] According to one aspect of the invention, the distribution channel has a generally L-shape.

[0043] According to one aspect of the present invention, the discharge channel has a generally L-shape.

[0044] According to one aspect of the present invention, the distribution channel and the discharge channel are mirror-symmetrical to each other, so that the heat transfer fluid inlet and the heat transfer fluid outlet are symmetrical to each other.

[0045] According to one aspect of the invention, the distribution channel and the discharge channel each comprise a flat area delimited on each side by a side portion.

[0046] According to one aspect of the invention, the flat area follows the path formed by the distribution channel and the discharge channel.

[0047] According to one aspect of the present invention, the distribution channel is configured to distribute the heat transfer fluid into a plurality of heat transfer fluid flow branches.

[0048] According to one aspect of the invention, the heat transfer fluid flow branches are parallel to each other.

[0049] According to one aspect of the present invention, the heat transfer fluid flow branches are connected to the distribution channel with spaces therebetween.

[0050] Therefore, the branch and the deceleration cavity are spaced apart by a certain distance.

[0051] According to one aspect of the present invention, the heat transfer fluid flow branches are connected to the distribution channel with regular intervals between the heat transfer fluid flow branches.

[0052] According to one aspect of the invention, the regular spacing is substantially equal to the width of the flow branches.

[0053] In an alternative embodiment, the heat transfer fluid flow branches are connected to the distribution channel with irregular spacing between the heat transfer fluid flow branches.

[0054] According to one aspect of the invention, the flow branches have substantially the same width as one another.

[0055] According to one aspect of the present invention, at least some of the heat transfer fluid circulation branches most upstream in the flow direction of the distribution channel are connected to the distribution channel via a deceleration cavity, while other heat transfer fluid circulation branches are not connected to the distribution channel via a deceleration cavity.

[0056] In an alternative embodiment, all heat transfer fluid flow branches each have a deceleration cavity.

[0057] According to one aspect of the invention, the flow branches are connected to one another by at least one crosspiece, in particular in the form of a straight strip.

[0058] According to one aspect of the invention, the flow branches comprise at least a pair of branches connected to each other by at least one crosspiece, in particular in the form of a straight strip.

[0059] According to one aspect of the invention, the two branches are connected to each other by a crosspiece only on the inner side of a pair of branches.

[0060] According to one aspect of the invention, the crosspiece is arranged perpendicular to each flow branch.

[0061] According to one aspect of the invention, the width of the crosspiece is substantially equal to the width of the flow branch.

[0062] According to one aspect of the invention, an opening is formed between two consecutive crosspieces.

[0063] According to one aspect of the invention, the opening has a substantially rectangular perimeter.

[0064] According to one aspect of the present invention, the deceleration chamber has a junction with the flow branch, the junction being different from the upstream junction and the downstream junction.

[0065] According to one aspect of the invention, the deceleration chamber has a size that decreases from one flow branch to another flow branch in the flow direction of the heat transfer fluid in the distribution channel.

[0066] Thus, the volume of the cavity decreases from one branch to another in the flow direction of the heat transfer fluid in the distribution channel.The size of the deceleration cavity can be adjusted according to the heat flow to be reduced.

[0067] According to one aspect of the invention, the deceleration cavity has a periphery that is in particular substantially rectangular in shape when the deceleration cavity is observed along an axis perpendicular to a plane defined by a placement area facing said cavity.

[0068] According to one aspect of the present invention, the rectangular perimeter of each deceleration cavity decreases from one cavity to another.

[0069] According to one aspect of the present invention, the height of the deceleration chamber is at its maximum at its junction with the distribution channel. According to one aspect of the present invention, the width of the deceleration chamber can also be greater than the width of the distribution channel and the branch channel, which allows heat to be collected from multiple cells under appropriate circumstances. In general, the present invention allows significant adjustment of the height and width to expand the thermal interface and reach more cells, thereby requiring greater fluid deceleration.

[0070] According to one aspect of the present invention, the height of the deceleration chamber at the junction with the branch channel is lower than the height of the deceleration chamber at the junction with the distribution channel.

[0071] According to one aspect of the present invention, due to the existence of the side portions of the distribution channel, the height of the deceleration chamber becomes different heights.

[0072] According to one aspect of the present invention, the height in the deceleration cavity is reduced, in particular, reduced by one or more levels, between the junction of the distribution channel and the deceleration cavity and the junction of the branch channel and the deceleration cavity.

[0073] According to one aspect of the invention, the hierarchy comprises:

[0074] a first level having a height, the first level being defined between a junction of the distribution passage and the deceleration cavity; and

[0075] A second level having a height is defined between a junction of the branch passage and the deceleration cavity.

[0076] According to one aspect of the present invention, the height of the deceleration cavity is defined along an axis perpendicular to a plane defined by a placement area facing said cavity.

[0077] According to one aspect of the invention, the deceleration chamber is locally formed by a recess in one of the plates of the forming device (in particular the lower plate), so that at the recess, the height of the deceleration chamber measured along an axis perpendicular to the plane defined by the placement area facing the deceleration chamber is reduced compared to the height of the first level defined between the junction of the distribution channel and the deceleration chamber.

[0078] According to one aspect of the present invention, the deceleration cavity has a size arranged to face at least two placement areas, preferably at least three placement areas.

[0079] According to one aspect of the present invention, the deceleration cavities have perimeters that exhibit different shapes relative to each other.

[0080] According to one aspect of the invention, the device comprises at least two placement areas forming a row of placement areas.

[0081] According to one aspect of the present invention, the device comprises a plurality of rows of placement areas parallel to each other, wherein each row comprises a plurality of placement areas.

[0082] According to one aspect of the invention, the rows of placement areas are arranged vertically along an axis defined relative to the maximum length of the dispensing channel.

[0083] According to one aspect of the invention, the device comprises an array of placement areas along the dispensing channel.

[0084] According to one aspect of the invention, the device comprises a row of placement areas along the discharge channel.

[0085] Furthermore, two current trends are observed for optimizing the heat exchange between heat transfer fluids and components. According to a first trend, the intention is to optimize the heat transfer coefficient as a function of the variation of the temperature difference between the heat transfer fluid circulation channels of the thermal regulating device. According to a second trend, the intention is to reduce the pressure difference between the various heat transfer fluid circulation channels. However, it has been found that designs based on reducing the temperature difference between the channels come at the expense of increasing the pressure difference between the channels, and vice versa. On the one hand, the application of a design based on reducing the pressure difference results in a very low heat exchange towards the heat transfer fluid outlet. On the other hand, the application of a design based on optimizing the heat transfer coefficient will result in a significant pressure difference between the channels. The present invention aims to overcome these drawbacks and in particular to optimize the heat exchange heat transfer coefficient while minimizing the pressure difference between the heat transfer fluid channels.

[0086] The invention therefore also relates to a device for thermal regulation of components whose operation is sensitive to temperature, wherein these components are in particular intended for energy storage and may be battery cells, in particular for vehicles, said device comprising:

[0087] -heat transfer fluid discharge channel;

[0088] at least two heat transfer fluid circulation branches, each of which opens into a collecting area of ​​the discharge channel so that the heat transfer fluid that has circulated in the branches is discharged through the heat transfer fluid discharge channel, wherein these collecting areas are distributed along the discharge channel; and

[0089] at least two placement areas, each placement area being arranged to receive the component, each placement area being in thermal contact with the heat transfer fluid discharge channel, so that the component placed in the placement area can exchange heat with the heat transfer fluid circulating in the heat transfer fluid discharge channel;

[0090] The collecting areas each have a cross-section that increases or remains constant when moving from one collecting area to the next collecting area in the direction of flow of the heat transfer fluid; and

[0091] For at least two consecutive collecting areas, the downstream collecting area has a larger cross-section than the upstream collecting area.

[0092] In the present invention, since the cross-section of the collection area increases by increasing the height, a constant exchange coefficient can be maintained throughout the flow as the outlet approaches. To this end, the pressure loss increases locally. In this case, the pressure gradient increases throughout the discharge channel.

[0093] It should be noted that the main factor contributing to the pressure difference is the average velocity of the fluid, which is proportional to the flow rate. In this case, the cross-section must increase at the same rate to maintain equal velocities.

[0094] Varying the cross-section of the fluid passages in the collecting areas allows for the velocity of the fluid passing through them to be adjusted. This allows the cooling capacity to be adjusted by the collecting areas, thereby balancing them. As a result, the temperature of the facing cells remains relatively uniform.

[0095] According to one aspect of the present invention, each placement area faces the heat transfer fluid discharge channel, so that the components placed in the placement area can exchange heat with the heat transfer fluid.

[0096] According to one aspect of the invention, the placement area is substantially flat.

[0097] According to one aspect of the invention, the height of the cross-sections of the collecting areas increases or remains constant when moving from one collecting area to the next in the direction of flow of the heat transfer fluid; and

[0098] For at least two consecutive collecting areas, the height of the downstream collecting area is greater than the height of the upstream collecting area, wherein the height is a dimension measured along an axis perpendicular to the placement plane.

[0099] According to one aspect of the invention, at least two consecutive collecting areas are spaced apart from one another by a section of the discharge channel having a predetermined length.

[0100] According to one aspect of the invention, the section of the outlet channel does not have any spoiler elements.

[0101] According to one aspect of the present invention, the height between each collection area increases by a predetermined factor. Notably, after each connection of a flow branch, the cross-section of the collection area increases by 40% to 60% of the cross-section of the channel from the flow branch. For example, if the cross-section of the collection area is 100 mm² before connecting a 20 mm² flow branch channel, then after connection, the cross-section of the collection area is 100 mm² + 50% × 20 = 110 mm². This is just one possible example.

[0102] It is also contemplated that, for example, following the flow direction, each time a channel adds its flow rate to the collecting area, the subsequent passage cross section increases by a predetermined value, for example, by a height of 1 mm.

[0103] According to one aspect of the present invention, the heat transfer fluid is glycol water.

[0104] According to one aspect of the invention, at least one of the collecting areas comprises at least one spoiler element.

[0105] According to one aspect of the invention, at least one of the collecting areas is free of any spoiler elements.

[0106] According to one aspect of the invention, at least one of the collecting areas comprises a set of spoiler elements comprising at least two spoiler elements.

[0107] According to one aspect of the invention, at least two collecting areas each comprise a set of spoiler elements comprising at least two spoiler elements.

[0108] According to one aspect of the invention, the dimensions of the spoiler elements of a group of spoiler elements are selected such that the disturbances in the heat transfer fluid caused by these spoiler elements decrease in intensity from one group of spoiler elements to another in the flow direction of the heat transfer fluid.

[0109] According to one aspect of the invention, the shapes of the spoiler elements of a spoiler element group are selected so that the disturbance of the heat transfer fluid caused by these spoiler elements decreases in intensity from one group of spoiler elements to another group in the flow direction of the heat transfer fluid.

[0110] According to one aspect of the invention, the number of spoiler elements of a spoiler element group is selected so that the disturbance of the heat transfer fluid caused by these spoiler elements decreases in intensity from one group of spoiler elements to another group of spoiler elements in the flow direction of the heat transfer fluid.

[0111] According to one aspect of the invention, the size, shape and / or number of the spoiler elements of the spoiler element groups are selected so that the disturbance of the heat transfer fluid caused by these spoiler elements decreases in intensity from one group of spoiler elements to another group of spoiler elements in the flow direction of the heat transfer fluid.

[0112] According to one aspect of the invention, the spoiler elements of a set of spoiler elements have the same shape as one another.

[0113] According to one aspect of the invention, the spoiler elements of a set of spoiler elements have shapes that differ from one another.

[0114] According to one aspect of the invention, the spoiler elements of a set of spoiler elements have the same dimensions as one another.

[0115] According to one aspect of the invention, the spoiler elements of a set of spoiler elements have dimensions that differ from one another.

[0116] According to one aspect of the invention, the spoiler element is dome-shaped, in particular with an elongated base or a circular base.The spoiler element may exhibit any other shape, such as a prism or a pyramid.

[0117] These spoiler elements can be arranged in different ways depending on the disturbance to be generated.

[0118] For example, the spoiler elements are arranged in alignment, or alternately on either side of a line.

[0119] According to one aspect of the invention, at least some of the spoiler elements may be arranged in a V-shaped pattern.

[0120] The disturbance intensity of the pattern formed by the spoiler element or these spoiler elements can be described as the ability to locally produce the conditions for triggering turbulence in the flow. For example, the V-shaped pattern causes the fluid to be concentrated before the cross-section is limited, while the circular dome-shaped spoiler element only affects this cross-section. Finally, the smooth channel is intended to have minimal disturbance, and therefore the disturbance intensity is the lowest. Therefore, the V-shaped pattern can be described as having a higher disturbance intensity than the elongated dome-shaped spoiler element, and the elongated dome-shaped spoiler element itself has a higher disturbance intensity than the circular dome-shaped spoiler element, and the circular dome-shaped spoiler element itself has a higher disturbance intensity than the smooth channel. Preferably, the spoiler element or the pattern formed by the spoiler element have different properties, and the disturbance intensity significantly reduces when approaching the outlet. For example, the dome-shaped spoiler element is placed closer to the outlet than the V-shaped one.

[0121] According to one aspect of the invention, the set of spoiler elements comprises at least one pair of spoiler elements formed by a first spoiler element and a second spoiler element, the first and second spoiler elements extending between a first base and a first ridge and between a second base and a second ridge, respectively, wherein the first ridge is elongated along a first straight line, the second ridge is elongated along a second straight line, the first straight line intersecting the second ridge, and a third straight line parallel to the general flow direction of the heat transfer fluid, the third straight line passing through the center of the first base intersecting the second base.

[0122] According to one aspect of the present invention, the first and second spoiler elements are dome-shaped, and particularly, each spoiler element has an elongated base. These spoiler elements advantageously form a bend with two closely spaced changes of direction, and the interval between these two spoiler elements in the pair is less than the interval between two such pairs. The closer these spoiler elements are to each other in the same pair, the more obvious the bend effect will be, so the disturbance intensity of the pair is higher. Usually, the disturbance intensity of this spoiler element pair is not as good as a V-shaped pattern, but is higher than independent circular or elongated dome pattern.

[0123] According to one aspect of the present invention, the intersection point between the first straight line and the third straight line forms an angle A, and the angle A ranges between 20° and 60°, in particular between 30° and 50°.

[0124] According to one aspect of the present invention, the intersection point between the second straight line and the third straight line forms an angle B, which ranges between 45° and 85°, in particular between 55° and 75°.

[0125] According to one aspect of the invention, angles A and B are selected so as to form a two-part V-shape.

[0126] The sharper the V, the greater the convergence effect and therefore the higher the intensity of the disturbance in terms of triggering turbulence. The sharper the V, the less close together two consecutive patterns can be placed, which results in the angle at the point of the V being advantageously between 55° and 75°.

[0127] According to one aspect of the invention, the height of the spoiler element ranges between 10% and 50% of the height of the discharge channel, preferably between 20% and 40% of the height of the discharge channel.

[0128] The invention also relates to a thermal regulation device for components whose operation is sensitive to temperature, wherein these components are in particular intended for energy storage and may be battery cells, in particular for vehicles, said device comprising:

[0129] - discharge channel;

[0130] a heat transfer fluid flow branch comprising a branch channel having an intermediate section between an upstream section and a downstream section, wherein these upstream section and downstream section pass through at least one component interior placement area in opposite directions;

[0131] a component end placement area distinct from the component interior placement area, wherein the component end placement area is at least partially in thermal contact with:

[0132] A heat transfer fluid flows through the middle section of the channel in the branch; and

[0133] discharge channel;

[0134] The components placed in the component end placement area can exchange heat with the following circulating heat transfer fluid:

[0135] in the middle section of the heat transfer fluid circulation branch; and

[0136] in the discharge channel; and

[0137] An intermediate section of the channel in the fluid flow branch comprises at least one heat transfer fluid disruptor element.

[0138] An "inner storage area" is understood to be an area that is at a certain distance from the exhaust channel. In other words, this inner area is cooled by the branch rather than by the exhaust channel. If the storage areas form a row, two "end storage areas" can be provided at opposite ends of the row, with the "inner storage area" located between the two end storage areas.

[0139] Due to the fact that the fluid flow disrupter elements are strategically placed on the middle section of the fluid circulation branch, the heat exchange between the component and the heat transfer fluid can be significantly increased without increasing the heat transfer fluid pressure loss, which will have the effect of limiting the circulation of the heat transfer fluid and therefore limiting the heat exchange between the heat transfer fluid and the component.

[0140] Therefore, this strategic arrangement of the heat transfer fluid disruptor elements represents the best compromise between maximizing heat exchange and minimizing heat transfer fluid flow pressure losses.

[0141] According to one aspect of the invention, the intermediate section forms a bend in the channel, in particular a 180° bend in the channel.

[0142] According to one aspect of the invention, the downstream section continues to another 180° bend in the channel, whereupon the channel ends in an end section comprising a spoiler element.

[0143] The bend in the channel, where the single pressure loss is significant due to its geometry, has proven to be one of the strategic locations for maximizing heat exchange. Thus, even though the heat transfer fluid is already hot, it can be optimally cooled by the time it reaches the outlet channel due to the presence of the heat transfer fluid turbulent element.

[0144] According to one aspect of the invention, the bend formed by the intermediate section has a U-shape.

[0145] According to one aspect of the invention, the upstream section and the downstream section are straight.

[0146] According to one aspect of the invention, the channel in the flow branch has additional bends, so that the fluid flow in the flow branch reaches at least two bends.

[0147] For example, the "additional bend" is located at the end of the branch opposite the bend formed by the middle section. The channel thus has, for example, a generally serpentine shape.

[0148] Two regions are said to "face" each other when they overlap when viewed along an axis perpendicular to the regions.

[0149] According to one aspect of the invention, the end placement area faces the discharge channel.

[0150] According to one aspect of the invention, the end placement area at least partially faces the middle section.

[0151] The surface area of ​​the portion of the end placement area facing the middle section (particularly in the form of a strip) accounts for 1% to 20%, preferably 1% to 10%, of the total surface area of ​​the end placement area.

[0152] The strip is at least 2 times, or 4 times, or 5 times, or 10 times smaller than the total surface area of ​​the end placement area.

[0153] In other words, a large portion of the end placement area faces the discharge channel.

[0154] According to one aspect of the present invention, a branch channel through which a heat transfer fluid flows includes an end section at the junction with the collecting area of ​​the discharge channel, and the end section includes at least one fluid disruptor element. The end section may also include a fluid flow constriction. The constriction allows for adjustment of the flow rate of the fluid flowing through the branch.

[0155] The constriction is preferably achieved by narrowing two facing walls to reduce the cross section, or by deforming two facing walls.The constriction is clearly different from a spoiler element, which can be made by narrowing a single wall by deformation.

[0156] According to one aspect of the invention, the end section with the fluid flow spoiler element extends over at least one third or at least half of the length of the branch.

[0157] According to one aspect of the invention, the end placement region is identically facing the middle section, the end section and the collecting region of the discharge channel.

[0181] definition

[0182] The z-axis is defined as the axis perpendicular to the plane defined by the placement area. The x-axis and y-axis are perpendicular to the z-axis such that they form an xyz trihedron.

[0183] The x-axis is, for example, the main extension axis of the distribution channel or the discharge channel. It should be noted that when the distribution channel or the discharge channel generally has an L-shape, the x-axis is parallel to the longest straight portion of the distribution channel or the discharge channel.

[0184] An example of a dimension measured along the x-axis is the width of the deceleration cavity. The deceleration cavities may have the same width as each other.

[0185] This definition of width applies analogously along the same x-axis to the other elements forming the device, ie for the width of the crosspieces, the width of the flow branches.

[0186] The y-axis is, for example, an axis parallel to a branch which extends perpendicularly to the main axis of extension.

[0187] An example of a dimension measured along the y-axis is the length of the deceleration cavity. The deceleration cavities may have different lengths from one another.

[0188] The term "upstream" refers to the side of a device that allows a heat transfer fluid to enter the device, or refers to the location of the heat transfer fluid before reaching a "downstream" location. For example, the term "upstream" will be used to refer to the relative location of the heat transfer fluid closer to a heat transfer fluid inlet or heat transfer fluid distribution channel.

[0189] The term "downstream" refers to the location of the heat transfer fluid after it reaches an "upstream" location.

[0190] The term "height of the collection area" is understood to mean the maximum height measured within the same collection area. This height is measured between the smooth, mutually facing walls of the collection area along an axis perpendicular to the plane of the placement area for receiving the components. This height is notably measured at a location in the collection area where no spoiler elements are present.

[0191] In the present invention, regions are said to "face" each other when two regions overlap when viewed along an axis perpendicular to the regions.

[0192] Figure 1 A module 2 is shown which comprises a thermal regulation device 4 for components 6 whose operation is sensitive to temperature, wherein these components 6 are in particular intended for energy storage and may be battery cells 6 , in particular for vehicles.

[0193] like Figures 1 to 3 As shown, the device 4 includes:

[0194] - a heat transfer fluid distribution channel 8 connected to a heat transfer fluid inlet 9;

[0195] - four heat transfer fluid deceleration cavities 10 , 12 , 14 , 16 through which the distribution channel 8 passes;

[0196] eight heat-transfer fluid circulation branches 100 , 102 , 104 , 106 , 108 , 110 , 112 , 114 , having substantially the same width as one another and being parallel to one another, through which the heat-transfer fluid from the distribution channel 8 is distributed;

[0197] - Eight rows 18, each row comprising a plurality of placement areas 200 for receiving components 6, said rows being arranged along the y-axis and parallel to one another, wherein these placement areas 200 face the heat transfer fluid deceleration chambers 10, 12, 14, 16, so that the components 6 placed in these placement areas 200 can exchange heat with the heat transfer fluid.

[0198] Each branch 100, 102, 104, 106, 108, 110, 112, 114 comprises a flat tray 21 comprising a plurality of placement areas 200 for receiving components 6. Eight rows of placement areas 18 are formed on these flat trays 21.

[0199] The device 4 further comprises a heat transfer fluid discharge channel 30. The discharge channel 30 is connected to a heat transfer fluid outlet 32.

[0200] The distribution channel 8 and the discharge channel 32 pass under the tray 21 .

[0201] The placement area 200 includes an inner placement area 202 and an end placement area 204 .

[0202] like Figure 1 As specifically shown in FIG, the “inner placement area” 202 is understood to refer to an area at a certain distance from the discharge channel 30. In other words, the inner area 202 is cooled by the branches 102, 104, 106, 108, 110, 112, rather than by the discharge channel 30. In the case where the placement areas 202, 204 form a row, two “end placement areas” 204 ​​can be provided at two opposite ends of the row, with the “inner placement area 202” being located between the two end placement areas 204.

[0203] The distribution channel 8 and the discharge channel 30 each have a generally L-shape and are mirror images of each other, so that the heat transfer fluid inlet 9 and the heat transfer fluid outlet 32 ​​are symmetrical to each other.

[0204] The end placement areas 204 are located on the longest straight portion of the distribution channel 8 and on the longest straight portion of the discharge channel 30 , respectively.

[0205] Heat transfer fluid circulation branches 100, 102, 104, 106 most upstream in the flow direction in distribution channel 8 are connected to deceleration chambers 10, 12, 14, 16, so that the heat transfer fluid that has passed through deceleration chambers 10, 12, 14, 16 is distributed to heat transfer fluid circulation branches 100, 102, 104, 106 leading to heat transfer fluid discharge channel 30. Other heat transfer fluid circulation branches 108, 110, 112, 114 are not connected to distribution channel 8 through circulation chambers.

[0206] like Figures 4 to 6 As specifically shown in the figure, the deceleration chambers 10, 12, 14, 16 have a first fluid passage cross-section S1, which is larger than the second passage cross-section S2 of the distribution channel 8 at the upstream junction 22 with the deceleration chambers 10, 12, 14, 16, and is larger than the third passage cross-section S3 of the distribution channel 8 at the downstream junction 24 with the deceleration chambers 10, 12, 14, 16.

[0207] By means of the present invention, the heat transfer fluid passing through the deceleration chamber 10, 12, 14, 16 is decelerated. Reducing the speed of the heat transfer fluid reduces the heat exchange, especially compared to the situation where the heat transfer fluid would not be decelerated in the absence of such a deceleration chamber 10, 12, 14, 16.

[0208] This has the effect that, when the heat transfer fluid reaches a low temperature, the components 6 in the placement area 200 facing the deceleration cavities 10, 12, 14, 16 are cooled to a lesser degree than if there were no such deceleration cavities 10, 12, 14, 16. This prevents the components 6 from being overcooled by the heat transfer fluid coming from the distribution channel 8.

[0209] Thus, the temperature imbalance between the first component 6 encountered by the heat transfer fluid and the remaining components 6 further downstream is reduced. Consequently, all components 6 can operate optimally because the temperature between the components 6 is more uniform.

[0210] Thus, the distribution channel 8 can be used to cool the components 6 placed on top of it. As a result, a greater number of components 6 can be placed on the thermal conditioning device 4 overall. For a given size of thermal conditioning device 4, this increases the energy storage capacity of the components 6 and therefore increases the range of the vehicle powered by this energy.

[0211] The heat transfer fluid circulation branches 100, 102, 104, 106, 108, 110, 112, 114 are connected to the distribution channel 40, and there is a regular spacing between the heat transfer fluid circulation branches 100, 102, 104, 106, 108, 110, 112, 114, wherein the regular spacing is substantially equal to the width of the circulation branches 100, 102, 104, 106, 108, 110, 112, 114 measured along the x-axis.

[0212] Therefore, the branches 100 , 102 , 104 , 106 and the deceleration cavities 10 , 12 , 14 , 16 are spaced apart at regular intervals.

[0213] like Figure 2 and Figure 5 As particularly shown in FIG. 1 , each of the heat transfer fluid circulation branches 100 , 102 , 104 , 106 , 108 , 110 , 112 , and 114 includes a serpentine branch channel 40 . The branch channel 40 has a passage section S4 connected to the heat transfer fluid exhaust path 40 .

[0214] Each of the deceleration chambers 10, 12, 14, 16 has a junction 25 with the flow branches 100, 102, 104, 106, which is different from the upstream junction 22 and the downstream junction 24. The junction 25 is connected to the branch channel 40 via a passage section S4.

[0215] like Figure 1 and Figure 2 As shown, the thermal conditioning device 4 comprises two plates 50 , 52 , namely an upper plate 50 and a lower plate 52 .

[0216] These plates 50 , 52 include protrusions, in particular produced by stamping, which can form, for example, the distribution channel 8 , the deceleration chambers 10 , 12 , 14 , 16 and the heat transfer fluid flow branches 100 , 102 , 104 , 106 , 108 , 110 , 112 , 114 , as well as the heat transfer fluid discharge channel 30 .

[0217] The upper plate 50 faces the component 6 and includes a plurality of placement areas 200. The lower plate 52 is defined as a plate having one face opposite to the face of the upper plate 50.

[0218] The two plates 50 , 52 may be welded or stamped in order to form the thermal conditioning device 4 .

[0219] The eight heat transfer fluid circulation branches 100, 102, 104, 106, 108, 110, 112, 114 include four pairs of branches, which are connected to each other by four crosspieces 60 in the form of straight strips, and the width of the four pairs of branches is substantially equal to the width of each circulation branch 100, 102, 104, 106, 108, 110, 112, 114, and the four pairs of branches are arranged perpendicular to each circulation branch 100, 102, 104, 106, 108, 110, 112, 114. These eight branches 100, 102, 104, 106, 108, 110, 112, 114 are connected to each other by crosspieces 60 only on the inner side of each pair of branches.

[0220] Between two consecutive crosspieces 60 an opening 70 having a substantially rectangular perimeter is formed.

[0221] like Figure 3 As shown, the size of the deceleration chambers 10 , 12 , 14 , 16 decreases from one flow branch 100 , 102 , 104 , 106 to another flow branch in the flow direction of the heat transfer fluid in the distribution channel 8 .

[0222] Thus, the volume of the cavities 10, 12, 14, 16 decreases from one branch 100, 102, 104, 106 to another in the flow direction of the heat transfer fluid in the distribution channel 8. The size of the deceleration cavities 10, 12, 14, 16 can be adjusted according to the heat flow to be reduced.

[0223] Further references Figure 3 and Figure 6 It can be seen that the size of the first deceleration cavity 100 is arranged to face three placement areas 200 .

[0224] The second deceleration cavity 102 is sized to face two to three placement areas 200 .

[0225] The third deceleration cavity 104 is sized to face the two placement areas 200 .

[0226] The fourth deceleration cavity 106 is sized to face one of the semi-placement areas 200 .

[0227] As in Figure 4 As can be seen in particular in FIG. 1 , the distribution channel 9 and the discharge channel 30 each comprise a flat area 80 delimited on each side by a side portion 82 .

[0228] The flat area 80 follows the path formed by the distribution channel 9 and the discharge channel 30 .

[0229] like Figures 3 to 5 As shown, the deceleration cavities 10 , 12 , 14 , 16 have a substantially rectangular perimeter when the deceleration cavity is viewed along the z-axis.

[0230] Throughout the remainder of the specification, the first deceleration cavity 10 is taken as an example. However, the features of the first deceleration cavity 10 are also valid for the other deceleration cavities 12 , 14 , 16 .

[0231] like Figure 5 and Figure 7 As shown, the height hd of the deceleration chamber 10 is maximum at the junctions 22, 24 with the distribution channel 8. The height hb in the deceleration chamber at the junction with the branch channel 40 is lower than the height hd at the junction with the distribution channel 8.

[0232] Due to the presence of the side portion 82 of the distribution channel 8 , the height hd of the deceleration chamber becomes the height hint1 .

[0233] Between the junction of the distribution channel 8 and the deceleration chambers 10 , 12 , 14 , 16 and the junction of the branch channel 40 and the deceleration chambers 10 , 12 , 14 , 16 , the height in the deceleration chambers 10 , 12 , 14 , 16 is reduced, in particular by two levels 84 , 86 .

[0234] A first level 84 having a height hint1 is defined between the junctions of the distribution passage 8 and the deceleration cavities 10 , 12 , 14 , 16 , and a second level 86 having a height hint2 is defined between the junctions of the branch passage 40 and the deceleration cavities 10 , 12 , 14 , 16 .

[0235] The deceleration cavities 10, 12, 14, 16 are locally formed by recesses 90 in one of the plates forming the device 4 (in particular the lower plate 52), so that at these recesses 90, the height hc of the deceleration cavities 10, 12, 14, 16 measured along the z-axis is reduced compared to the height hint of the first level 84 defined between the junction of the distribution channel 8 and the deceleration cavities 10, 12, 14, 16.

[0236] Heights hd, hb, hc, hint1, and hint2 are defined along the z-axis.

[0237] like Figure 1 and Figure 8 As shown, the heat regulating device 4 includes:

[0238] seven heat transfer fluid circulation branches 100 , 102 , 104 , 106 , 108 , 110 , 112 , each comprising a branch channel 40 having a middle section 120 between an upstream section 130 and a downstream section 140 , the upstream section 130 and the downstream section 140 being straight, wherein these upstream sections 130 and downstream sections 140 pass oppositely through at least one component interior placement area 202 ;

[0239] A component end placement area 204 that is different from the component inner placement area 202 and that is at least partially in thermal contact with:

[0240] The heat transfer fluid flows through the middle section 120 of the channel 40 in the branches 102, 104, 106, 108, 110, 112; and

[0241] Exhaust channel 30;

[0242] The component 6 placed in the component end placement area 204 can exchange heat with the following circulating heat transfer fluid:

[0243] in the middle section 120 of the heat transfer fluid circulation branches 102 , 104 , 106 , 108 , 110 , 112 ; and

[0244] in the exhaust passage 30; and

[0245] The intermediate section 120 of the channels in the fluid flow branches 102 , 104 , 106 , 108 , 110 , 112 comprises a heat transfer fluid disruptor element 150 in the shape of a dome with an elongated base.

[0246] The end placement area 204 faces the outlet channel 30 and at least partially faces the middle section 120 .

[0247] Due to the fact that the fluid flow disrupter elements 150 are strategically placed on the middle section 120 of the fluid circulation branches 102, 104, 106, 108, 110, 112, the heat exchange between the component 6 and the heat transfer fluid can be significantly increased without increasing the heat transfer fluid pressure losses, which will have the effect of limiting the circulation of the heat transfer fluid and therefore have the effect of limiting the heat exchange between the heat transfer fluid and the component 6.

[0248] Thus, this strategic placement of the heat transfer fluid disruptor elements 150 represents an optimal compromise between maximizing heat exchange and minimizing heat transfer fluid flow pressure losses.

[0249] The middle section 120 forms a 180° bend in the channel, which has a U-shape.

[0250] The downstream section 140 continues into another 180° bend in the channel before the channel 40 ends in an end section 160 that includes a spoiler element 152 .

[0251] The bend in the channel 40 is a location where the pressure loss is significant due to its geometry and has proven to be one of the strategic locations for maximizing heat exchange. Thus, the heat transfer fluid, although already hot, can be optimally cooled by the time it reaches the outlet channel 30 due to the presence of the heat transfer fluid disruptor element 150.

[0252] Channel 40 has an additional bend 170 at the ends of branches 102 , 104 , 106 , 108 , 110 , 112 opposite the bend formed by intermediate section 120 , so that the fluid flow in branches 102 , 104 , 106 , 108 , 110 , 112 reaches both bends.

[0253] The surface area of ​​the portion of the end placement area 204 in the form of a strip 206 facing the middle section is 1% to 20%, preferably 1% to 10%, of the total surface area of ​​the end placement area 204. This strip 206 is at least 10 times smaller than the total surface area of ​​the end placement area.

[0254] In other words, most of the end placement area 204 faces the discharge channel 30 .

[0255] The end section 160 is connected to a collecting region of the outlet channel 180 , which is part of the outlet channel 30 , and comprises a fluid flow disruptor element 154 .

[0256] like Figure 2 and Figure 8 As shown, the end section 160 with the fluid flow spoiler element 154 extends over at least half of the length of the branch 1 .

[0257] The end placement area 204 faces the middle section 120 , the end section 160 and the collecting area 180 of the outlet channel 30 .

[0258] The outlet channel 30 is smooth, in other words, has no spoiler elements 154 outside the collecting region 160 .

[0259] The channels 40 in the branches 100 , 102 , 104 , 106 , 108 , 110 , 112 are smooth, in other words, are free of spoiler elements 152 outside the middle section 120 and the end section 160 .

[0260] like Figure 2 and Figure 8 As shown, the device 4 includes:

[0261] six heat transfer fluid circulation branches 100, 102, 104, 106, 108, 110, 112, each of which opens into a collecting area 180 of the discharge channel 30, so that the heat transfer fluid that has circulated in the branches 100, 102, 104, 106, 108, 110, 112 is discharged through the heat transfer fluid discharge channel 30, wherein these collecting areas 180 are distributed along the discharge channel 30; and

[0262] a plurality of placement areas 200, each placement area 200 being arranged to receive a component 6, wherein each placement area 200 is in thermal contact with the heat transfer fluid discharge channel 30, such that the component 6 placed in the placement area 200 can exchange heat with the heat transfer fluid flowing in the heat transfer fluid discharge channel 30, wherein the placement area 200 is substantially flat;

[0263] The collecting areas 180 each have a cross section St that increases or remains constant when transitioning from one collecting area 180 to the next in the flow direction of the heat transfer fluid; and

[0264] For at least two consecutive collecting areas 180 , the downstream collecting area has a larger cross section St than the upstream collecting area.

[0265] In the present invention, because the cross-section of the collection area 180 increases by increasing the height, a constant exchange coefficient can be maintained along the flow as it approaches the outlet. Consequently, the pressure loss increases locally. In this case, the pressure gradient increases along the discharge channel 30.

[0266] It should be noted that the main factor contributing to the pressure difference is the average velocity of the fluid, which is proportional to the flow rate. In this case, the cross section St must be increased at the same rate to maintain equal velocities.

[0267] like Figure 9 and10 As shown, cross-sections Sc of the collection region 180 corresponding to branches 112 and 102, respectively, have heights hu and hd, respectively.

[0268] When moving from the collecting area 180 upstream of the branch 112 to the collecting area 180 downstream of the branch 102 in the flow direction of the heat transfer fluid, the height of the collecting area 180 increases.

[0269] In other words, the height hd of the collection area 180 downstream of the branch 102 is greater than the height hu of the collection area 180 upstream, where the heights hd and hu are dimensions measured along the z-axis.

[0270] like Figure 8 As shown, the width of the collecting area 180 measured along the x-axis is substantially equal to the dimension of the branch measured along the same x-axis. Two consecutive collecting areas 180 are separated from each other by a section of the discharge channel 182 having a predetermined length. Each section of the discharge channel 182 does not have any spoiler element 154.

[0271] The height between each collecting area 180 increases by a predetermined factor. For example, following the flow direction, each time the channel increases its flow rate in the collecting area, the subsequent passage portion increases by a predetermined value, for example, 1 mm in height.

[0272] The collection area 180 includes four to six spoiler elements 154 .

[0273] The spoiler elements 154 are dome-shaped, have an elongated base or have a circular base. The spoiler elements 154 may have any other shape, such as a prism or a pyramid.

[0274] These spoiler elements 154 may be arranged in different ways depending on the disturbance to be generated.

[0275] For example, the spoiler elements 154 are arranged in alignment, or alternately on either side of a line.

[0276] As in Figures 9 and 10 As can be seen in FIG, the height of the spoiler element 154 measured along the z-axis is in the range between 10% and 50% of the height of the outlet channel.

[0277] refer to Figure 2 , the collecting area 180 receiving the heat transfer fluid from the first deceleration cavity 10 has no spoiler element.
