Description

Title of the invention: Thermal regulation device for components

[0001] The present invention relates to a thermal regulation device for components. The present invention relates to a module comprising such a thermal regulation device for components.

[0002] The present invention further relates to a method of assembling such a thermal regulation device.

[0003] It is now common practice to equip electric, internal combustion, or hybrid vehicles with electrical energy storage components that provide power to the various vehicle components. These electrical energy storage components are generally composed of electrical energy storage cells positioned within a battery pack.

[0004] Today, car manufacturers are seeking to provide more powerful electric or hybrid vehicles with increased electric range. To achieve this, more and more battery packs, and / or increasingly larger battery packs, are being installed on these electric or hybrid vehicles. It is known to install all or at least some of these battery packs in the vehicle floor, essentially across the entire width of the vehicle.

[0005] It is understood that, during vehicle operation, battery packs can generate a significant amount of heat and therefore be subject to temperature increases that can, in some cases, cause damage or even destruction. Consequently, cooling them is essential to maintain their condition and thus ensure the vehicle's reliability, range, and performance. Furthermore, the operation of battery packs may be less efficient at low temperatures, as the electrical or electronic components equipping these battery packs then require a warm-up period before operating at full capacity.

[0006] To achieve this, 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.

[0007] These thermal regulation devices are generally traversed by a heat transfer fluid which can, depending on the needs, either absorb the heat emitted by each battery pack in order to cool it or supply heat if the temperature of the battery pack is insufficient for its proper functioning.

[0008] The temperature of the heat transfer fluid flowing through the thermal regulation device changes when the heat transfer fluid is in thermal contact with said components.

[0009] The heat transfer fluid, when it arrives at a low temperature in order to cool the components, tends to cool the first components it encounters more than the rest of the components downstream, because the heat transfer fluid has not had time to be heated by the components.

[0010] The temperature imbalance created between the first components and the rest of the downstream components is likely to lead to suboptimal operation of the components whose operation is sensitive to temperature.

[0011] The present invention aims to overcome this drawback, and in particular to avoid an imbalance in terms of temperature for the first components compared to the rest of the downstream components.

[0012] The invention thus relates to a thermal regulation device for components whose operation is sensitive to temperature, these components being in particular intended for energy storage and being able to be battery cells, particularly for vehicles, said device comprising:

[0013] - a heat transfer fluid distribution channel;

[0014] - a heat transfer fluid slowing cavity through which the dis-channel passes distribution, the slowing cavity having a first fluid passage section that is both larger than a second passage section of the distribution channel at an upstream junction with the slowing cavity, and a third passage section of the distribution channel at a downstream junction with the slowing cavity,

[0015] - a heat transfer fluid circulation branch in which fluid is distributed heat transfer fluid from the distribution channel, and

[0016] - at least one placement area for receiving said component, this area of placement being opposite the heat transfer fluid slowing cavity so that a component placed in this placement area can exchange heat with the heat transfer fluid.

[0017] Two zones are said to be "opposite" when these zones overlap when observed along an axis perpendicular to these zones.

[0018] Thanks to the invention, the heat transfer fluid passing through the slowing cavity is slowed down. The reduction in the speed of the heat transfer fluid decreases the heat exchange, particularly compared to the case where the heat transfer fluid would not be slowed down in the absence of such a slowing cavity.

[0019] This has the effect of cooling the component located on the placement area opposite the slowing cavity less than in the case where such a slowing cavity is absent, when the heat transfer fluid arrives with a low temperature. In this way, overcooling of the component by the heat transfer fluid from the distribution channel is avoided.

[0020] Thus, the temperature imbalance between the first components encountered by the heat transfer fluid and the remaining downstream components is reduced. Consequently, all components can operate optimally due to greater temperature homogeneity among them.

[0021] Thus, it is possible to use the distribution channel to cool components placed upon it. This allows for a greater number of components to be placed on the thermal regulation device. This increases the energy storage capacity of the components for a given size of thermal regulation device, and thus increases the range of a vehicle powered by this energy.

[0022] Advantageously, the invention makes it possible to reduce the temperature imbalance while promoting the reduction of the pressure drop compared to a channel without a slowing cavity.

[0023] Furthermore, in battery pack applications, there is usually a significant constraint on the total available height (or available vertical space), which can limit the channel height. One aspect of the invention makes it possible to increase the cross-sectional area of ​​the distribution channel without increasing the height. This promotes fluid velocity and heat transfer from the cells because the larger the cross-sectional area of ​​the distribution channel, the greater the number of cells that can be in contact.

[0024] According to one aspect of the invention, the heat transfer fluid circulation branch connects to the deceleration cavity so that 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 evacuation channel.

[0026] According to one aspect of the invention, the circulation branch opens onto the heat transfer fluid discharge channel.

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

[0028] According to one aspect of the invention, the circulation branch comprises at least one branch channel of straight shape connecting to the heat transfer fluid discharge channel.

[0029] According to one aspect of the invention, the circulation branch comprises at least one serpentine-shaped branch channel connecting to the heat transfer fluid discharge channel.

[0030] According to one aspect of the invention, the circulation branch comprises at least two branch channels of straight shape, each branch channel connecting to the heat transfer fluid discharge channel.

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

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

[0033] According to one aspect of the invention, at least one of these plates comprises reliefs, in particular formed by stamping. These reliefs can form, for example, the distribution channel, the slowing cavity and the heat transfer fluid circulation branch as well as the heat transfer fluid discharge channel.

[0034] According to one aspect of the invention, one of the plates faces the components. This plate is defined as the upper plate and includes at least one placement area. The other plate, whose face is opposite that of the upper plate, is defined as the lower plate.

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

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

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

[0038] According to one aspect of the invention, the distribution channel passes under this tray.

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

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

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

[0042] According to one aspect of the invention, the distribution channel has a general L-shaped form.

[0043] According to one aspect of the invention, the drainage channel has a general L-shaped form.

[0044] According to one aspect of the invention, the distribution and evacuation channels are mirror-symmetric to each other so that the heat transfer fluid inlet and the heat transfer fluid outlet are symmetric to each other.

[0045] According to one aspect of the invention, the distribution and drainage channels each have a flat surface bordered on each side by a flank.

[0046] According to one aspect of the invention, the flat surface follows the path formed by the distribution and evacuation channels.

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

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

[0049] According to one aspect of the invention, these heat transfer fluid circulation branches connect to the distribution channel with a pitch between the heat transfer fluid circulation branches.

[0050] Thus, the branches and slowing cavities are spaced apart from each other with a pitch.

[0051] According to one aspect of the invention, these heat transfer fluid circulation branches connect to the distribution channel with a regular pitch between the heat transfer fluid circulation branches.

[0052] According to one aspect of the invention, the regular pitch is substantially equal to the width of the traffic branch.

[0053] In an alternative embodiment, these heat transfer fluid circulation branches connect to the distribution channel with an irregular pitch between the heat transfer fluid circulation branches.

[0054] According to one aspect of the invention, the traffic branches have substantially the same width between them.

[0055] According to one aspect of the invention, at least some of the upstream heat transfer fluid circulation branches in the direction of flow in the distribution channel are each connected to the distribution channel by means of a slowing cavity. The other heat transfer fluid circulation branches are not connected to the distribution channel by means of a slowing cavity.

[0056] In an alternative embodiment, all the heat transfer fluid circulation branches each have a slowing cavity.

[0057] According to one aspect of the invention, the traffic branches are connected to each other by at least one cross member, in particular a cross member in the form of a straight strip.

[0058] According to one aspect of the invention, the traffic branches comprise at least one pair of branches connected to each other by at least one cross member, 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 the crossbar only inside the pair of branches.

[0060] According to one aspect of the invention, the cross member is arranged perpendicular to each branch of circulation.

[0061] According to one aspect of the invention, the cross member has a width substantially equal to the width of the traffic branch.

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

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

[0064] According to one aspect of the invention, the deceleration cavity has a junction with the circulation branch that differs from the upstream and downstream junctions.

[0065] According to one aspect of the invention, the slowing cavities have dimensions which decrease from one circulation branch to another in the direction of flow of heat transfer fluid in the distribution channel.

[0066] Thus, the volume of the cavities decreases from one branch to the other in the direction of heat transfer fluid flow in the distribution channel. The dimensions of the slowing cavity can be adapted according to the heat flux that one wishes to reduce.

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

[0068] According to one aspect of the invention, the rectangular perimeter of each slowing cavity is smaller from one cavity to another.

[0069] According to one aspect of the invention, the slowing cavity has a maximum height at its junction with the distribution channel. According to another aspect of the invention, the width of the slowing cavity can also be greater than those of the distribution and branch channels, which allows, where appropriate, the collection of heat from several cells. Generally speaking, the invention allows for significant variation in height, and also in width, to broaden the thermal interfaces and reach more cells, resulting in the need for greater fluid deceleration.

[0070] According to one aspect of the invention, the height in the slowing cavity at the junction with the branch channel is less than the height at its junction with the distribution channel.

[0071] According to one aspect of the invention, the height of the slowing cavity changes to a different height due to the presence of a flank of the distribution channel.

[0072] According to one aspect of the invention, between the junction of the distribution channel with the slowing cavity and the junction of the branch channel and the slowing cavity, the height in the slowing cavity decreases, in particular by a or several levels.

[0073] According to one aspect of the invention, the bearings comprise: - a first stage having a height, the first stage being defined between the junction of the distribution channel with the slowing cavity; and - a second tier having a height, the second tier being defined between and the junction of the branch channel and the slowing cavity.

[0074] According to one aspect of the invention, the height of the slowing cavity is defined along the axis perpendicular to the plane defined by the placement area opposite said cavity.

[0075] According to one aspect of the invention, the slowing cavity is formed locally by a recess in one of the plates forming the device, in particular the lower plate, so that at the level of this recess, the height of the slowing cavity measured along the axis perpendicular to the plane defined by the placement area opposite the slowing cavity is reduced compared to the height of the first bearing defined between the junction of the distribution channel with the slowing cavity.

[0076] According to one aspect of the invention, the slowing cavity has dimensions arranged to be opposite at least two placement zones, preferably at least three placement zones.

[0077] According to one aspect of the invention, the slowing cavities have contours of different shapes relative to each other.

[0078] According to one aspect of the invention, the device comprises at least two placement zones forming a row of placement zones.

[0079] According to one aspect of the invention, the device comprises rows of placement zones that are parallel to each other. Each row comprises a plurality of placement zones.

[0080] According to one aspect of the invention, the rows of placement zones are arranged perpendicularly along an axis defined with respect to the greatest length of the distribution channel.

[0081] According to one aspect of the invention, the device comprises a row of placement zones along the distribution channel.

[0082] According to one aspect of the invention, the device comprises a row of placement zones along the discharge channel.

[0083] Furthermore, two current trends are observed for optimizing heat exchange between the heat transfer fluid and the components. According to the first trend, the aim is to optimize the heat transfer coefficient as a function of the temperature difference between the heat transfer fluid circulation channels of the thermal control device. According to the second trend, the aim is to reduce The pressure differences between the various heat transfer fluid circulation channels are a concern. However, it has been observed that the design based on reducing the temperature difference between the channels comes at the expense of increasing the pressure differences between the channels, and vice versa. On the one hand, applying the design based on reducing the pressure difference results in very low heat exchange at the heat transfer fluid outlet. On the other hand, applying the design based on optimizing the heat transfer coefficient will result in a large pressure difference between the channels. The present invention aims to overcome these drawbacks, and in particular to optimize the heat transfer coefficient while minimizing the pressure difference between the heat transfer fluid channels.

[0084] The invention also relates to a thermal regulation device for temperature-sensitive components, these components being intended in particular for energy storage and being battery cells, particularly for vehicles, said device comprising:

[0085] - a heat transfer fluid discharge channel;

[0086] - at least two heat transfer fluid circulation branches which open each in a collection zone of the drain channel so that heat transfer fluid that has circulated in the branches is drained through the heat transfer fluid drain channel, these collection zones being distributed along the drain channel, and

[0087] - at least two placement areas, each arranged to receive said component, each placement zone being in thermal contact with the heat transfer fluid discharge channel so that a component placed in that placement zone can exchange heat with heat transfer fluid circulating in the heat transfer fluid discharge channel,

[0088] each collection zone has a cross-section that increases or remains constant when moving from one collection zone to the next in the direction of heat transfer fluid flow, and

[0089] for at least two consecutive collection zones, the downstream collection zone has a larger cross-section than the upstream collection zone.

[0090] In the invention, because the collection zones have a cross-section that increases with increasing height as one approaches the outlet, it is possible to maintain a constant heat transfer coefficient along the flow. To this end, the pressure drop is locally increased. In this case, the pressure gradient increases along the discharge channel.

[0091] It should be noted that the main factor contributing to the pressure difference is the average fluid velocity, which is proportional to the flow rate. In this case, the cross-section must to be increased in the same ratio to remain at the same speed.

[0092] Varying the cross-sectional area of ​​the fluid passages in the collection zones allows the velocity of the fluid passing through them to be adjusted. This makes it possible to regulate the cooling capacity of each collection zone individually and thus balance them. As a result, the temperatures of the opposing cells are relatively homogeneous.

[0093] According to one aspect of the invention, each placement zone is opposite the heat transfer fluid discharge channel so that a component placed in this placement zone can exchange heat with the heat transfer fluid.

[0094] According to one aspect of the invention, the placement areas are substantially flat.

[0095] According to one aspect of the invention, the cross-section of these collection zones has a height that increases or remains constant when moving from one collection zone to the next in the direction of heat transfer fluid flow, and

[0096] for at least two consecutive collection zones, the downstream collection zone has a greater height than the upstream collection zone, the height being a dimension measured along an axis perpendicular to the plane of the location.

[0097] According to one aspect of the invention, at least two consecutive collection zones are separated from each other by a section of the discharge channel having a predetermined length.

[0098] According to one aspect of the invention, the section of the discharge channel is free of disturbance elements.

[0099] According to one aspect of the invention, the height between each collection zone increases by a predetermined factor. In particular, after each connection of a circulation branch, the cross-sectional area of ​​the collection zone is increased by 40% to 60% of that of the channel coming from the circulation branch. For example, if the collection zone has a cross-sectional area of ​​100 mm², before a 20 mm² channel from the circulation branch connects to it, the cross-sectional area of ​​the collection zone after the connection is 100 + 50% x 20 = 110 mm². This is only one possible example.

[0100] It is also possible to foresee, for example, by following the direction of the flow, that each time a channel adds its flow in the collection zone, then the next passage section increases by a predetermined value, for example by 1 mm in height.

[0101] According to one aspect of the invention, the heat transfer fluid is glycol water.

[0102] According to one aspect of the invention, at least one of the collection zones comprises at least one element of disruption.

[0103] According to one aspect of the invention, at least one of the collection areas is free of a disturbing element.

[0104] According to one aspect of the invention, at least one of the collection zones comprises a group of perturbation elements comprising at least two perturbation elements.

[0105] According to one aspect of the invention, at least two of the collection zones each comprise a group of disturbance elements comprising at least two disturbance elements.

[0106] According to one aspect of the invention, the dimensions of the perturbation elements of the groups of perturbation elements are chosen so that the perturbations in the heat transfer fluid due to these perturbation elements are less and less strong from one group of perturbation elements to another depending on the direction of flow of the heat transfer fluid.

[0107] According to one aspect of the invention, the shape of the perturbation elements of the groups of perturbation elements is chosen so that the perturbations in the heat transfer fluid due to these perturbation elements are less and less strong from one group of perturbation elements to another depending on the direction of flow of the heat transfer fluid.

[0108] According to one aspect of the invention, the number of perturbation elements in the groups of perturbation elements is chosen so that the perturbations in the heat transfer fluid due to these perturbation elements are less and less strong from one group of perturbation elements to another depending on the direction of flow of the heat transfer fluid.

[0109] According to one aspect of the invention, the dimensions, shape, and / or number of the perturbation elements of the groups of perturbation elements are chosen so that the perturbations in the heat transfer fluid due to these perturbation elements are less and less strong from one group of perturbation elements to another according to the direction of flow of the heat transfer fluid.

[0110] According to one aspect of the invention, the perturbation elements of a group of perturbation elements have the same shape among themselves.

[0111] According to one aspect of the invention, the perturbation elements of a group of perturbation elements have different shapes from each other.

[0112] According to one aspect of the invention, the perturbation elements of a group of perturbation elements have the same dimensions with respect to each other.

[0113] According to one aspect of the invention, the perturbation elements of a group of perturbation elements have different dimensions between them.

[0114] According to one aspect of the invention, the perturbation element is dome-shaped, in particular with an elongated base or a circular base. The perturbation element may have any other shape, for example prism or pyramid or other

[0115] These disturbance elements can be arranged in different ways depending on the disturbances that one wishes to generate.

[0116] For example, these disturbance elements are arranged in an aligned or alternating manner on either side of a line.

[0117] According to one aspect of the invention, at least some of the disturbance elements can be arranged in the form of chevron patterns.

[0118] The aggressiveness of perturbation elements or the patterns formed by these perturbation elements can be described as the capacity to locally create the conditions for triggering turbulence in the flow. For example, a chevron pattern causes a concentration of the flow before the cross-section is restricted, whereas a round dome-shaped perturbation element only affects the cross-section. Finally, a smooth channel aims for the least amount of perturbation, and therefore the least aggressiveness. Thus, a chevron pattern can be said to be more aggressive than an elongated dome-shaped perturbation element, which is itself more aggressive than a round dome-shaped perturbation element, which is itself more aggressive than a smooth channel. Preferably, the perturbation elements or the patterns formed by the perturbation elements are of a different nature, and in particular, become less and less aggressive as one approaches the outlet.For example, dome-shaped disturbance elements are placed closer to the exit than chevrons.

[0119] According to one aspect of the invention, the disturbance element group comprises at least one pair of disturbance elements consisting of a first disturbance element and a second disturbance element, said first and second disturbance elements extending respectively between a first base and a first ridge and between a second base and a second ridge, said first ridge being in an elongated form along a first straight line and said second ridge being in an elongated form along a second straight line, said first straight line intersecting said second ridge, and a third straight line parallel to the general direction of flow of heat transfer fluid, said third straight line passing through the center of the first base intersecting the second base.

[0120] According to one aspect of the invention, the first and second perturbation elements are dome-shaped, in particular each perturbation element having an elongated base. These perturbation elements advantageously form a baffle with two closely spaced changes of direction, and the spacing between these two perturbation elements in the pair is smaller than the spacing between two such pairs. The closer these perturbation elements are in the same pair, the more pronounced the baffle effect will be, and therefore the more aggressive the pair will be. Generally, the aggressiveness of such a pair of perturbation elements is less than that of a chevron pattern but greater than that of an individual round or elongated dome pattern.

[0121] According to one aspect of the invention, the intersection between the first line and the The third line forms an angle A, which is between 20° and 60°, specifically between 30° and 50°.

[0122] According to one aspect of the invention, the intersection between the second line and the third line forms an angle B, which is between 45° and 85°, in particular between 55° and 75°.

[0123] According to one aspect of the invention, angles A and B are chosen so as to form a two-part chevron.

[0124] The sharper the chevron, the greater the convergent effect, and therefore the more aggressive it will be in terms of triggering turbulence. The sharper the chevron, the less likely two consecutive patterns can be brought close together, which advantageously results in a chevron tip angle between 55 and 75°.

[0125] According to one aspect of the invention, the height of the disturbance element is between 10 and 50% of the height of the discharge channel, preferably between 20 and 40% of the height of the discharge channel.

[0126] The invention also relates to a thermal regulation device for temperature-sensitive components, these components being intended in particular for energy storage and possibly being battery cells, particularly for vehicles, said device comprising:

[0127] - a drainage channel;

[0128] - a heat transfer fluid circulation branch comprising a branch channel having an intermediate section located between an upstream section and a downstream section, these upstream and downstream sections passing opposite at least one internal component placement zone;

[0129] - a component end placement area different from the area of internal component placement, this component end placement area being at least partially in thermal contact with: • the intermediate section of the channel in the heat transfer fluid circulation branch; and • the drainage channel; so that a component placed in this component end placement zone can exchange heat with circulating heat transfer fluid: • in the intermediate section of the heat transfer fluid circulation branch; and • in the drainage channel; and the intermediate section of the channel in the fluid circulation branch includes at least one element of disturbance to the flow of heat transfer fluid.

[0130] The term “inner placement zone” means a zone that is distant from the discharge channel, namely that this inner zone is cooled by the branch and not by the discharge channel. When the placement areas form a row, two "end placement areas" may be provided at the two opposite ends of the row, while the "inner placement area" is located between these two end placement areas.

[0131] Thanks to the fact that said fluid flow disturbance element is strategically placed on the intermediate section of the fluid circulation branch, it is possible to significantly increase the heat exchanges between the component and the heat transfer fluid, without increasing the pressure losses of the heat transfer fluid, which would 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.

[0132] Thus, this strategic placement of the heat transfer fluid flow disturbance element presents an optimal compromise between maximizing heat exchange and minimizing heat transfer fluid flow pressure losses.

[0133] According to one aspect of the invention, the intermediate section forms a bend in the canal, in particular a 180° canal bend.

[0134] According to one aspect of the invention, the downstream section extends to another 180° canal bend, then the canal ends with a terminal section which includes disturbance elements.

[0135] The bend in the channel, a point where singular pressure losses are significant due to its geometry, proves to be one of the strategic points for maximizing heat exchange. In this way, the heat transfer fluid, although already hot, can be optimally cooled upon entering the discharge channel due to the presence of the heat transfer fluid flow disturbance element.

[0136] According to one aspect of the invention, the bend formed by the intermediate section has a U-shaped form.

[0137] According to one aspect of the invention, the upstream and downstream sections are straight.

[0138] According to one aspect of the invention, the channel in the circulation branch presents an additional turn so that the fluid flow in the traffic branch completes at least two turns.

[0139] For example, the "additional bend" is located at one end of the branch opposite the bend formed by the intermediate section. The channel thus has, for example, a general serpentine shape.

[0140] Two zones are said to be "opposite" when these zones overlap when observed along an axis perpendicular to these zones.

[0141] According to one aspect of the invention, the end placement area is opposite the discharge channel.

[0142] According to one aspect of the invention, the end placement zone is at least partially opposite the intermediate section.

[0143] The area of ​​the portion of the end placement area, in particular in the form of a strip, which is opposite the intermediate segment represents 1% to 20%, preferably 1% to 10%, of the total area of ​​the end placement area.

[0144] This strip is at least 2 times, or 4 times, or 5 times, or 10 times smaller than the total area of ​​the end placement zone.

[0145] In other words, the major part of the end placement area is opposite the discharge channel.

[0146] According to one aspect of the invention, the channel of the heat transfer fluid circulation branch comprises a terminal section junction with a collection zone of the discharge channel, and this terminal section comprises at least one fluid flow disturbance element. This terminal section optionally includes a fluid flow restriction. This restriction allows the flow rate of fluid circulating in the branch to be adjusted.

[0147] The constriction is preferably achieved by reducing the cross-section through a narrowing or by deforming two opposing walls. The constriction differs in particular from the perturbation element, which can be created from a narrowing by deforming a single wall.

[0148] According to one aspect of the invention, the terminal section with fluid flow disturbance elements extends over at least one-third, or at least half, of the branch length.

[0149] According to one aspect of the invention, the end placement area is opposite both the intermediate section, the terminal section and the collection area of ​​the discharge channel.

[0150] According to one aspect of the invention, the collection area is a portion of the drainage channel.

[0151] According to one aspect of the invention, the discharge channel is smooth, namely free of disturbance elements, outside the collection area.

[0152] According to one aspect of the invention, the channel in the branch is smooth, namely devoid of disturbance elements, apart from the intermediate section and the terminal section.

[0153] According to one aspect of the invention, the intermediate section comprises a plurality of disturbance elements, in particular dome-shaped, in particular with an elongated base.

[0154] According to a particular embodiment, the intermediate section comprises more disturbance elements than the upstream and downstream sections.

[0155] The invention also relates to a module comprising:

[0156] - the thermal regulation device according to the invention, and

[0157] - a plurality of components placed on the placement areas of the re device thermal regulation, with at least one of these placement zones being opposite at least one of: the heat transfer fluid distribution channel the heat transfer fluid slowing cavity; the heat transfer fluid discharge channel.

[0158] The features, variants, and different embodiments of the invention can be combined in various ways, provided they are not incompatible or mutually exclusive. In particular, variants of the invention may be conceived comprising only a selection of features, described hereafter in isolation from the other described features, if this selection of features is sufficient to confer a technical advantage and / or to differentiate the invention from the prior art.

[0170] Definitions

[0171] The z-axis is defined as an axis perpendicular to the plane defined by the placement zone. The x and y axes are perpendicular to the z-axis so as to form an xyz trihedron.

[0172] The x-axis is, for example, the main extension axis of the distribution channel or the discharge channel. In particular, when the distribution channel or the discharge channel has a general L-shape, the x-axis is parallel to the longest straight portion of the distribution channel or the discharge channel.

[0173] An example of a dimension measured along this x-axis is the width of the deceleration cavity. The deceleration cavities can have the same width.

[0174] This definition of width applies in a similar way along the same x-axis for the other elements forming the device, namely for the width of the crossbeam, the width of the traffic branch.

[0175] The y-axis is, for example, an axis parallel to the branches extending perpendicularly to the main extension axis.

[0176] An example of a dimension measured along this y-axis is the length of the slowing cavity. The slowing cavities may have different lengths.

[0177] The term "upstream" refers to the side of the device through which the heat transfer fluid is admitted into the device, or to the position of the heat transfer fluid before reaching the "downstream" position. For example, the term "upstream" will be used to designate the relative position of the heat transfer fluid closest to a heat transfer fluid inlet or heat transfer fluid distribution channel.

[0178] The term "downstream" refers to the position of the heat transfer fluid after it has reached the "upstream" position.

[0179] The term "collection zone height" refers to the maximum height measured within a single collection zone. This height is measured along an axis perpendicular to the plane of the placement zone for receiving a component, between facing smooth walls of the collection zone. This height is measured, in particular, at locations within the collection zone that are free of any disturbing elements.

[0180] In the present invention, two zones are said to be "opposite" when these zones overlap when observed along an axis perpendicular to these zones.

[0181] Figure [1] shows a module 2 comprising a thermal regulation device 4 for temperature-sensitive components 6, these components 6 being in particular intended for energy storage and being able to be battery cells 6, in particular for vehicles.

[0182] As can be seen in Figures 1 to 3, said device 4 comprises:

[0183] - a heat transfer fluid distribution channel 8 connected to a heat transfer fluid inlet loporteur 9,

[0184] - four heat transfer fluid slowing cavities 10, 12, 14, 16 through which the distribution channel 8,

[0185] - eight heat transfer fluid circulation branches 100, 102, 104, 106, 108, 110, 112, 114 having substantially the same width between them and parallel to each other in which heat transfer fluid is distributed from the distribution channel 8,

[0186] - eight rows 18 each comprising a plurality of placement zones 200 for to receive the components 6, the said rows being arranged along a y-axis and parallel to each other, these placement zones 200 being opposite the heat transfer fluid slowdown cavities 10, 12, 14, 16 so that the components 6 placed in these placement zones 200 can exchange heat with heat transfer fluid.

[0187] Each branch 100, 102, 104, 106, 108, 110, 112, 114 has a flat tray 21 having a plurality of placement zones 200 for receiving the components 6. The eight rows of placement zones 18 are formed on these flat trays 21.

[0188] The device 4 further includes a heat transfer fluid discharge channel 30. The discharge channel 30 is connected to a heat transfer fluid outlet 32.

[0189] The distribution and drainage channels 8, 32 pass under the trays 21.

[0190] The placement areas 200 include the inner placement areas and end placement areas 202, 204.

[0191] As illustrated in particular in [Fig.1], the "inner placement zone" 202 is understood to be a zone which is distant from the discharge channel 30, namely that this inner zone 202 is cooled by the branches 102, 104, 106, 108, 110, 112 and not by the discharge channel 30. When the placement zones 202, 204 form a row, two "end placement zones" 204 may be provided at the two opposite ends of the row, while the "inner placement zone" 202 is located between these two end placement zones 204.

[0192] The distribution and evacuation channels 8, 30, each having a general L-shape, are mirror-symmetric to each other so that the heat transfer fluid inlet 9 and the heat transfer fluid outlet 32 ​​are symmetric to each other.

[0193] The end placement areas 204 are respectively located on the longest straight portion of the distribution channel 8 and on the longest straight portion of the discharge channel 30.

[0194] The upstream heat transfer fluid circulation branches 100, 102, 104, 106 in the direction of flow in the distribution channel 8 connect to the slowing cavities 10, 12, 14, 16 so that heat transfer fluid having passed through the slowing cavities 10, 12, 14, 16 and distributed into the heat transfer fluid circulation branches 100, 102, 104, 106 which open into the heat transfer fluid evacuation channel 30. The other heat transfer fluid circulation branches 108, 110, 112, 114 are without connection to the distribution channel 8 by a circulation cavity.

[0195] As illustrated in particular in Figures 4 to 6, the slowing cavities 10, 12, 14, 16 have a first fluid passage section SI which is both larger than a second passage section S2 of the distribution channel 8 at an upstream junction 22 with the slowing cavities 10, 12, 14, 16 and a third passage section S3 of the distribution channel 8 at a downstream junction 24 with the slowing cavities 10, 12, 14, 16.

[0196] Thanks to the invention, the heat transfer fluid passing through the slowing cavities 10, 12, 14, 16 is slowed down. The reduction in the speed of the heat transfer fluid decreases the heat exchange, particularly compared to the case where the heat transfer fluid would not be slowed down in the absence of such slowing cavities 10, 12, 14, 16.

[0197] This results in less cooling of the components 6 located in the placement areas 200 opposite the cooling cavities 10, 12, 14, 16 compared to the case where such cooling cavities 10, 12, 14, 16 are absent, when the heat transfer fluid arrives at a low temperature. In this way, overcooling of the components 6 by the heat transfer fluid from the distribution channel 8 is prevented.

[0198] Thus, the temperature imbalance between the first components 6 encountered by the heat transfer fluid and the remaining components 6 downstream is reduced. Consequently, all components 6 can operate optimally due to greater temperature homogeneity among them.

[0199] Thus, it is possible to use the distribution channel 8 to cool components 6 placed upon it. This allows for a greater number of components 6 to be arranged overall on the thermal regulation device 4. This increases the energy storage capacity of the components 6 for a given size of thermal regulation device 4, and thus increases the range of a vehicle powered by this energy.

[0200] The heat transfer fluid circulation branches 100, 102, 104, 106, 108, 110, 112, 114 connect to the distribution channel 40 with a regular pitch between the heat transfer fluid circulation branches 100, 102, 104, 106, 108, 110, 112, 114, said regular pitch being substantially equal to the width of the circulation branch 100, 102, 104, 106, 108, 110, 112, 114 measured along the x-axis.

[0201] Thus, branches 100, 102, 104, 106 and deceleration cavities 10, 12, 14, 16 are spaced from each other with a regular pitch.

[0202] As illustrated in particular in Figures 2 and 5, each heat transfer fluid circulation branch 100, 102, 104, 106, 108, 110, 112, 114 comprises a serpentine branch channel 40. The branch channel 40 has a cross-sectional area S4 connecting to the heat transfer fluid discharge channel 40.

[0203] The slowing cavities 10, 12, 14, 16 each have a junction 25 with the circulation branches 100, 102, 104, 106 different from the upstream and downstream junctions 22, 24. The junction 25 connects to the branch channel 40 having the passage section S4.

[0204] As shown in Figures 1 and 2, the thermal regulation device 4 comprises two plates 50, 52, namely an upper plate 50 and a lower plate 52.

[0205] These plates 50, 52 include reliefs, in particular produced by stamping. These reliefs can form, for example, the distribution channel 8, the slowing cavities 10, 12, 14, 16 and the heat transfer fluid circulation branches 100, 102, 104, 106, 108, 110, 112, 114 as well as the heat transfer fluid discharge channel 30.

[0206] The upper plate 50 faces the components 6 and has a plurality of placement zones 200. The lower plate 52 is defined as the plate whose face is opposite that of the upper plate 50.

[0207] The two plates 50, 52 can be welded or stamped so as to form the thermal regulation device 4.

[0208] The eight heat transfer fluid circulation branches 100, 102, 104, 106, 108, 110, 112, 114 comprise four pairs of branches connected to each other by four cross members 60 in the form of a straight strip and having a width substantially equal to the width of each circulation branch 100, 102, 104, 106, 108, 110, 112, 114, and arranged perpendicularly 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 the cross members 60 only within each pair of branches.

[0209] An opening 70 having a substantially rectangular perimeter is formed between the two successive crossbars 60.

[0210] As shown in [Fig.3], the slowing cavities 10, 12, 14, 16 have dimensions which decrease from one circulation branch 100, 102, 104, 106 to the other in the direction of flow of heat transfer fluid in the distribution channel 8.

[0211] Thus, the volume of the cavities 10, 12, 14, 16 decreases from one branch 100, 102, 104, 106 to the other in the direction of flow of heat transfer fluid in the distribution channel 8. The dimensions of the slowing cavities 10, 12, 14, 16 can be adapted according to the heat flux that one wishes to reduce.

[0212] Still referring to Figures 3 and 6, we see that the first cavity of the weaving 100 has dimensions arranged to be opposite three placement zones 200.

[0213] The second slowing cavity 102 has dimensions arranged to be opposite between two and three placement zones 200.

[0214] The third slowing cavity 104 has dimensions arranged to be opposite two placement zones 200.

[0215] The fourth slowing cavity 106 has dimensions arranged to be opposite one and a half placement zones 200.

[0216] As can be seen in particular in [Fig.4], the distribution and evacuation channels 9, 30 each have a flat 80 bordered on each side by a flank 82.

[0217] The flats 80 follow the path formed by the distribution and evacuation channels 9, 30.

[0218] As can be seen in figures 3 to 5, the deceleration cavities 10, 12, 14, 16 have a perimeter in an essentially rectangular shape, when the deceleration cavities are observed along the z-axis.

[0219] In what follows, the first slowing cavity 10 is taken as an example. However, the characteristics of the first slowing cavity 10 are also valid for the other slowing cavities 12, 14, 16.

[0220] As illustrated in figures 5 and 7, the slowing cavity 10 has a height hd which is maximum at its junction 22, 24 with the distribution channel 8. The height in the slowing cavities hb at the junction with the branch channel 40 is less than the height hd at its junction with the distribution channel 8.

[0221] The height of the slowing cavity hd changes to a height hintl due to the presence of the flank 82 of the distribution channel 8.

[0222] Between the junction of the distribution channel 8 with the slowing cavities 10, 12, 14, 16 and the junction of the branch channel 40 and the slowing cavities 10, 12, 14, 16, the height in the slowing cavities 10, 12, 14, 16 decreases, in particular by two steps 84, 86.

[0223] The first step 84 having a height hintl is defined between the junction of the distribution channel 8 with the slowing cavities 10, 12, 14, 16 and the second step 86 having a height hint2 is defined between and the junction of the branch channel 40 and the slowing cavities 10, 12, 14, 16.

[0224] The slowing cavities 10, 12, 14, 16 are formed locally by indentations 90 in one of the plates forming the device 4, in particular the lower plate 52, so that at the level of these indentations 90, the height hc of the slowing cavities 10, 12, 14, 16 measured along the z-axis are reduced relative to the height hint of the first step 84 defined between the junction of the distribution channel 8 with the slowing cavities 10, 12, 14, 16.

[0225] The heights hd, hb, hc, hintl, hint2 are defined along the z-axis.

[0226] As can be seen in Figures 1 and 8, the thermal regulation device 4 comprises:

[0227] - the seven heat transfer fluid circulation branches 100, 102, 104, 106, 108, 110, 112 each comprising the branch channel 40 having an intermediate section 120 situated between an upstream section 130 and a downstream section 140 which are straight, these upstream and downstream sections 130, 140 passing opposite at least one internal placement zone of component 202;

[0228] - a component end placement area 204 different from the area of internal placement of component 202, this end placement area of ​​component 204 being at least partially in thermal contact with: • the intermediate section 120 of channel 40 in the heat transfer fluid circulation branches 102, 104, 106, 108, 110, 112; and • the drainage channel 30; so that a component 6 placed in this end placement zone of component 204 can exchange heat with circulating heat transfer fluid: • in the intermediate section 120 of the heat transfer fluid circulation branches 102, 104, 106, 108, 110, 112; and • in the drainage channel 30; and the intermediate section of channel 120 in the fluid circulation branches 102, 104, 106, 108, 110, 112 includes heat transfer fluid flow disturbance elements 150 in the form of an elongated base dome.

[0229] The end placement area 204 is opposite the drainage channel 30 and is at least partially opposite the intermediate section 120.

[0230] Thanks to the fact that said fluid flow disturbance elements 150 are strategically placed on the intermediate section 120 of the fluid circulation branches 102, 104, 106, 108, 110, 112, it is possible to significantly increase the heat exchanges between component 6 and the heat transfer fluid, without increasing the pressure losses of the heat transfer fluid, which would have the effect of limiting the circulation of the heat transfer fluid, and therefore limiting the heat exchange between the heat transfer fluid and component 6.

[0231] Thus, this strategic placement of the heat transfer fluid flow disturbance elements 150 presents an optimal compromise between maximizing heat exchange and minimizing heat transfer fluid flow pressure losses.

[0232] The intermediate section 120 forms a 180° bend in the canal with a U-shape.

[0233] The downstream section 140 extends to another 180° canal bend, then the channel 40 ends with a terminal section 160 which includes disturbance elements 152.

[0234] The bend in channel 40, a point where singular pressure losses are significant due to its geometry, proves to be one of the strategic points for maximizing heat exchange. In this way, the heat transfer fluid, although already hot, can be optimally cooled upon arrival at the discharge channel 30 due to the presence of the heat transfer fluid flow disturbance elements 150.

[0235] Channel 40 has an additional bend 170 located at one end of branches 102, 104, 106, 108, 110, 112, opposite to the bend formed by the intermediate section 120 so that the flow of fluid in the circulation branches 102, 104, 106, 108, 110, 112 makes two bends.

[0236] The area of ​​the portion of the end placement area 204 in the form of a strip 206 which is opposite the intermediate segment represents 1% to 20%, preferably 1% to 10%, of the total area of ​​the end placement area 204. This strip 206 is at least 10 times smaller than the total area of ​​the end placement area.

[0237] In other words, the major part of the end placement area 204 is opposite the discharge channel 30.

[0238] The terminal section 160 is in junction with a collection zone of the discharge channel 180 which is a portion of the discharge channel 30, and this terminal section 160 includes fluid flow disturbance elements 154.

[0239] As illustrated in Figures 2 and 8, the terminal section 160 with fluid flow disturbance elements 154 extends over at least half the length of the branch 1.

[0240] The end placement area 204 is opposite both the intermediate section 120, the terminal section 160 and the collection area 180 of the discharge channel 30.

[0241] The discharge channel 30 is smooth, i.e. free from disturbance elements 154, outside the collection zone 160.

[0242] Channel 40 in branches 100, 102, 104, 106, 108, 110, 112 is smooth, i.e. devoid of disturbance elements 152, apart from the intermediate section 120 and the terminal section 160.

[0243] As illustrated in Figures 2 and 8, device 4 comprises:

[0244] - six heat transfer fluid circulation branches 100, 102, 104, 106, 108, 110, 112 each of which opens into a collection zone 180 of the discharge channel 30 so that heat transfer fluid having circulated in branches 100, 102, 104, 106, 108, 110, 112 is discharged via the heat transfer fluid discharge channel 30, these zones of collection 180 being distributed along the drainage canal 30, and

[0245] - a plurality of placement zones, each 200 arranged to receive the component 6, each placement zone 200 being in thermal contact with the heat transfer fluid discharge channel 30 so that a component 6 placed in this placement zone 200 can exchange heat with heat transfer fluid circulating in the heat transfer fluid discharge channel 30, this placement zone 200 being substantially flat,

[0246] The collection zones 180 each have a cross-sectional area St which increases or remains constant when moving from one collection zone 180 to the next in the direction of heat transfer fluid flow, and

[0247] for at least two consecutive collection zones 180, the downstream collection zone has a larger cross-section St than the upstream collection zone.

[0248] In the invention, because the collection zones 180 have a cross-section that increases with increasing height as one approaches the outlet, it is possible to maintain a constant heat transfer coefficient along the flow. To this end, the pressure drop is locally increased. In this case, the pressure gradient increases along the discharge channel 30.

[0249] It should be noted that the main factor contributing to the pressure difference is the average fluid velocity, which is proportional to the flow rate. In this case, the cross-sectional area St must be increased in the same ratio to maintain iso-velocity.

[0250] As illustrated in figures 9 and 10, the cross sections Sc of the collection zones 180 corresponding respectively to branches 112 and 102 have respectively a height hu and a height hd.

[0251] The height of the collection zone 180 increases when moving from a collection zone 180 upstream of branch 112 to the collection zone 180 downstream of branch 102 in the direction of heat transfer fluid flow.

[0252] In other words, the downstream collection zone 180 of branch 102 has a greater height hd than the height hu of the upstream collection zone 180, the heights hd and hu being dimensions measured along the z-axis.

[0253] As shown in [Fig. 8], the width of the collection zone 180 measured along the x-axis is substantially equal to the dimension of the branches measured along the same x-axis. The two consecutive collection zones 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 is free of disturbance elements 154.

[0254] The height between each collection zone 180 increases by a predetermined factor. For example, following the direction of flow, each time a channel adds its flow into the collection zone, the next passage section increases by a predetermined value, for example, 1 mm in height.

[0255] The collection areas 180 comprise between four and six disturbance elements 154.

[0256] These perturbation elements 154 are dome-shaped with an elongated base or with a circular base. These perturbation elements 154 may have any other shape, for example prism or pyramid or other.

[0257] These perturbation elements 154 can be arranged in different ways depending on the perturbations that one wishes to generate.

[0258] For example, these disturbance elements 154 are arranged in an aligned or alternating manner on either side of a line.

[0259] As can be seen in Figures 9 to 10, the height of the disturbance elements 154 measured along the z-axis is between 10 and 50% of the height of the discharge channel.

[0260] With reference to [Fig.2], the collection zone 180 receiving the heat transfer fluid from the first slowing cavity 10 is free of any disturbance element.
