Description

Technical field

[0001] The present invention relates to devices for cooling, ventilating, or heating components. In particular, the present invention relates to a device for controlling the temperature of a component, in particular an electrical component. Furthermore, the present invention relates to a temperature control arrangement, a control device, and a vehicle. Technical background and task

[0002] Modern means of transport such as motor vehicles or motorcycles are increasingly being equipped with driver assistance systems that use sensor systems to detect the environment, recognize traffic situations, and assist the driver, e.g., by braking or steering intervention or by issuing a visual or acoustic warning. Radar sensors, lidar sensors, camera sensors, or similar sensors are regularly used as sensor systems for environmental detection. The data acquired by the sensors can then be used to draw conclusions about the environment, which can be used, for example, to classify objects and / or the environment or to create an environment model. Furthermore, environmental detection is almost indispensable in the field of (semi-)autonomous driving, so there is particular interest in the further development and enhancement of the corresponding systems.Electronic control units (ECUs) or central control units (HPCs) are generally used to control actuators (brakes, engines, transmissions, etc.) and / or sensors, as well as to calculate and control driving and assistance functions.

[0003] Control units of many types often generate considerable waste heat, i.e. power loss, whereby the power loss of the control units can be dissipated in different ways depending on the ambient conditions, e.g. via cooling. Various forms of cooling methods are known, e.g. natural convection, in which heated air, which is lighter than cooler air, rises and the incoming colder air warms up and then also rises. Furthermore, forced convection can also be provided, in which, for example, a flow of air is blown or sucked over the components to be cooled by means of fans, whereby the heated air is dissipated. There are also fluid cooling systems, in particular liquid cooling systems, in which the components to be cooled are cooled, e.g. using cooling liquids (e.g. actively by forcing the cooling liquid past the components to be cooled by means of a pump).In addition, numerous mixed forms and variants as well as further cooling options for the systems shown, such as heat conduction to a cooler point, are known.

[0004] In some cases, control units also need to be heated to create optimal conditions for their operation. Some systems that can be used for cooling can also be used for heating. For example, a system that actively forces a cooling medium past a component can also use a heating medium.

[0005] Furthermore, heat that needs to be dissipated can be dissipated to the outside through a thermally conductive housing, such as a metal housing. With high power dissipation, the challenge is to dissipate the heat as effectively as possible on the surface or at least on one side of the housing to protect the components inside from overheating.

[0006] There are various forms of cooling, e.g. air cooling, possibly with cooling fins, or a closed coolant circuit that can be connected to the control unit housing. Liquid cooling is increasingly used in modern vehicles, as it is already present in electric or hybrid vehicles due to the various electronics on board, and can therefore be shared with other control units. If, for example, a housing is built around an electronic control unit for robustness reasons, the heat to be dissipated is often led to the outside through a thermally conductive metal housing. Heat dissipation through metal is a preferred heat dissipation method. Here, with the help of the good thermal conductivity of the metal, the heat is transported, for example, to a coolant that flows or flows in a channel in the metal housing.

[0007] However, this method has the disadvantage that multiple components on a circuit board often need to be cooled. Height tolerances (e.g., due to the geometry of the electronic components on the circuit board) and expansion coefficients must generally be taken into account. This means that the metal housing should not, or cannot, come into direct contact with the components to be cooled, which creates gaps that can reduce cooling performance. Therefore, pastes, adhesives, or pads with significantly lower thermal conductivity are used to bridge these gaps. This typically results in significant losses in thermal conductivity. Another disadvantage of previous solutions is the use of very complex, expensive housings that contain, for example, water channels. Special tubes are often embedded in the housing to achieve cooling performance.Complex designs of today's fluid-cooled control unit housings, as well as large gaps that must be routed to the metal housing components using heat transfer fluids, and larger housing dimensions are common disadvantages of such control units. Another disadvantage is that if the modules or component configurations on the circuit boards are changed, the housing often also has to be modified, as the metal must be brought close to the electronic components without colliding due to changes in component heights, nor can the distances or gaps become too large to guarantee sufficient cooling performance.

[0008] In addition to the challenges and disadvantages described above, new types of control units generally also require good EMC (electromagnetic compatibility) shielding to prevent both emitted and radiated interference. Circuit boards or parts thereof are often housed in metal enclosures. This presents a particular challenge in rack systems that have multiple electronic circuit boards that require cooling. Typically, circuit boards or plug-in cards are used here, and these should also be easy to install, remove, and replace. However, this is difficult to achieve with conventional fluid cooling systems, as the cooling plates of the liquid cooling system would have to be brought close to the individual plug-in cards in the rack if easy separation is required, for example, for servicing.Bringing the fluid directly to the individual plug-in cards via hydraulic connectors is particularly complex and generally undesirable due to sealing and handling issues.

[0009] Therefore, for example, DE 10 2021 209 640 A1 proposes a cooling device that has a heat sink that serves to accommodate a cooling medium. The heat sink has an inlet and an outlet for the cooling medium and is made at least partially of flexible material. The heat sink or a flexible part of the heat sink conforms to the component to be cooled, compensating for tolerances, as soon as the heat sink is filled with coolant or is actively flowed through by the coolant. In other words, an elastic bellows or bag adapts to the component to be cooled, for example a populated circuit board, when the coolant flows through it, thereby compensating for height differences. However, this presents a further problem, because the flow velocity of the coolant will also fluctuate significantly due to the variable cross-section of the cooling device and the tolerance-related fluctuations of the components to be cooled.This can greatly reduce the cooling effect, for example because a laminar flow changes into a turbulent one.

[0010] DE 10 2022 207 570 A1 relates to a cooling device for an assembly to be cooled in a vehicle, comprising at least two rigid outer shells, each having a circumferential connecting region, and an expandable film core which has a variable volume and is connected in a fluid-tight manner to the connecting regions of the at least two rigid outer shells such that the at least two rigid outer shells delimit a coolant channel, wherein the expandable film core is designed to vary a distance between the connecting regions of the at least two rigid outer shells and thus a height of the cooling device between a minimum height and a maximum height via its variable volume, as well as a rack with at least one such cooling device and a method for assembling such a cooling device.

[0011] US 2017 / 0 357 297 A1 relates to a cooling device, for example, for computer hardware. The device comprises a deformable outer chamber having at least one heat-conducting portion suitable for thermal contact with a heat source of computer hardware. The outer chamber is deformable upon a pressure increase therein. The cooling device further comprises at least one inner chamber embedded in the outer chamber, the volume of which can expand upon a pressure increase therein. The invention further relates to a computer hardware device comprising such a cooling device or stacks of such cooling devices paired with corresponding sets of electronic components.

[0012] US 2004 / 0 190 255 A1 relates to a water-cooling type cooling shell for an electronic device, comprising a bag body made of a soft, loose, elastic material that is deformable by contact pressure to come into close contact with heat-generating elements of various shapes and that accommodates a coolant, and a coolant inlet pipe and a coolant outlet pipe formed on one side of the bag body to allow the coolant to circulate in the bag body and connected to coolant circulation lines for circulating the coolant.Therefore, the water cooling jacket for electronic devices can be adapted to various shapes of heat-generating elements with uneven surfaces and various installation spaces, beyond electrical and mechanical limitations, to increase the heat transfer area and maximize heat transfer efficiency. It can be installed on various electronic devices such as hard disk drives, graphics cards, or memory cards, and PCBs without spatial limitations. Furthermore, a soft water cooling jacket for electronic devices can reduce manufacturing costs by simplifying the structure while maintaining tight adhesion, and safely protect various elements by distributing the pressure exerted on the elements.

[0013] It is therefore the object of the present invention to provide a device for tempering a component that eliminates at least one of the aforementioned disadvantages. Furthermore, it is the object of the invention to provide a corresponding tempering arrangement, a control device, and a vehicle. Disclosure of the invention

[0014] The object is achieved according to the invention by the features of the main claims. Advantageous embodiments can be found in the subclaims.

[0015] According to a first aspect of the invention, a device for temperature control of a component comprises an outer body that serves to accommodate a temperature control medium. The outer body has a first inlet and an outlet for the temperature control medium, as well as an inner wall. The outer body consists at least partially of a first flexible material, such that the outer body or a flexible part of the outer body conforms to the component when the temperature control medium flows through the outer body.

[0016] The outer body and / or the flexible part of the outer body can be designed, for example, in the form of a hose, an (elastic) bellows, a bag (without a frame), or the like. The inner wall results from the inside of the mold. If the outer body is realized as a tube, the inner wall is understood to be the inner wall. With a cuboid-shaped outer body, the inner wall is formed by the four wall surfaces within the cuboid.

[0017] The component can be any component to be temperature controlled. For example, it could be a processor, an electronic control unit (ECU), a high-performance computer (HPC), or a sensor. Temperature control describes the process of cooling, heating, or stabilizing the temperature of the component. The temperature control medium is used for heat exchange between the component and the cooling medium, which flows through the outer body along a flow direction. The flow direction is defined from the first inlet, through which the temperature control medium is admitted into the outer body, to the outlet, through which the temperature control medium can leave the outer body again.

[0018] Parts of the outer body consist of a first flexible material that can deform. When the temperature control medium flows through the outer body, the flexible part of the outer body adapts to the external conditions, such as the geometry of the component or pressure differences. Other parts of the outer body can be made of inflexible (or rigid) materials, in particular the first inlet and outlet, for example, to provide a robust interface to other system components such as hoses. For example, the first flexible material can be a metal foil or a plastic film.

[0019] Furthermore, the device comprises an inner body arranged within the outer body such that it has no contact with at least part of the inner wall of the outer body. The inner body consists at least partially of a second flexible material and is designed as a hollow body closed on one side with a second inlet. The second inlet faces the first inlet of the outer body.

[0020] By arranging the second inlet of the inner body towards the first inlet of the outer body, when the temperature control medium is admitted into the outer body via the first inlet, the outer body is also filled with the temperature control medium. The inner body does not have a dedicated outlet; instead, it is closed, for example, on the side facing the outlet of the outer body. The pressure difference between the second inlet and the outlet creates a hydrostatic effect such that the inner body is pushed or inflated towards the inner wall of the outer body. The inner body or its outer wall is at least not in contact with the inner wall everywhere, so that a fluid channel is created between the inner body and outer body. This can also be referred to as a cooling channel. The speed of the temperature control medium adapts to the changed volume ratios.This creates a defined fluid flow on the surfaces to be tempered.

[0021] To ensure that the inner body can also expand when the temperature control medium penetrates it, at least parts of the inner body are made of a second flexible material. This can be identical to the first flexible material, but different flexible materials can also be used. The dimensions of the inner body (the geometric design of the hollow body closed on one side) can be used to determine the distance between the inner wall of the outer body and the outer wall of the inner body (the expansion of the cooling channel) for a given temperature control medium speed. This significantly determines the temperature control properties, such as heat transfer and the like.

[0022] In other words, the one-sided closed hollow body (inner body) inside the flexible fluid tube (outer body) expands due to a static / dynamic fluid pressure, but adaptively does not come into contact with the inner wall of the fluid tube.

[0023] In an advantageous embodiment, at least one spacer is arranged between the inner wall of the outer body and an outer wall of the inner body. Such a spacer serves to delimit the cooling channel created between the inner wall of the outer body and the inner body. This allows the maximum extent of the cooling channel to be defined. The at least one spacer can be connected to the inner body or the outer body in a form-fitting or material-fitting manner. The at least one spacer can be hollow or solid.

[0024] In an advantageous embodiment, the at least one spacer is pyramid-shaped and / or conical.

[0025] Other geometric configurations are also conceivable. For example, the at least one spacer can be designed as a cylinder, cuboid, or similar.

[0026] In an advantageous embodiment, metal foil or plastic foil is provided for the first flexible material and / or the second flexible material. In particular, aluminum foil, copper foil, or plastic foil can be produced easily and cost-effectively.

[0027] In an advantageous embodiment, a laminate or composite film is provided for the first flexible material and / or the second flexible material. The laminate or composite film can, in particular, comprise the metal foil and / or the plastic film. The durability and stability of the outer or inner body can thus be easily improved. Furthermore, the outer or inner body can be adapted to the properties of the temperature control medium or the ambient conditions.

[0028] In an advantageous embodiment, the first flexible material and / or the second flexible material has a coating. An aluminum coating is particularly advantageous for improving the properties with regard to stability, impermeability, aging resistance, and durability. Anoxal coatings (anodized process = an aluminum oxide layer is created on the surface of the aluminum by anodic polarization of the aluminum) or Eloxal coatings (electrolytic oxidation of aluminum, whereby an oxide protective layer is created on the aluminum by anodic oxidation) are particularly suitable as a coating for an aluminum foil.

[0029] In an advantageous embodiment, the outer body has a first rigid region and at least one first flexible region. In particular, the first inlet corresponds to the first rigid region, for example, to provide a robust interface to other system components such as hoses. The outlet can also be particularly advantageously characterized by a rigid region. The first flexible region, on the other hand, is advantageously used where the temperature control effect is to be achieved through contact between the outer body and the component.

[0030] In an advantageous embodiment, the inner body has a second rigid region and at least one second flexible region. The second inlet particularly advantageously corresponds to the second rigid region, with the remainder of the inner body corresponding to the second flexible region.

[0031] In an advantageous embodiment, water, glycol, a water-glycol mixture, air, or CO2 is provided as the temperature control medium. These media are particularly suitable for flowing through an external body as described here.

[0032] According to a second aspect of the invention, a temperature control arrangement comprises an electrical component and a device for temperature control of the electrical component, as described above. The electrical component and the device are arranged such that thermal energy can be exchanged between them. For example, the device rests on the electrical component and is fixed there with appropriate force. However, the device can also enclose the electrical component, which is possible due to the flexible design.

[0033] In an advantageous embodiment, a printed circuit board and / or a circuit carrier and / or a plug-in card and / or a battery and / or a control unit and / or a processor is provided as the electrical component. These components have special cooling / heating requirements, which can be met by the flexible application possibilities of the device.

[0034] According to a third aspect of the invention, a control device comprises a device as described above or a temperature control arrangement as described above. Control devices such as ECUs, HPCs, or sensors particularly benefit from the device or temperature control arrangement according to the invention.

[0035] According to a fourth aspect of the invention, a vehicle comprises a control device as described above. Summary of the characters

[0036] The invention is explained in more detail below using exemplary embodiments with the aid of figures. The figures show: Fig. 1: A side view of a first embodiment of a device for tempering a component; Fig. 2: A side view of a first embodiment of a temperature control arrangement with the device from Fig. 1; Fig. 3: A front view of the temperature control arrangement from Fig. 2; Fig. 4: A top view of the tempering arrangement from Fig. 2. Fig. 5: A front view of a second embodiment of a tempering arrangement; Fig. 6: A side view of a third embodiment of a temperature control arrangement; and Fig. 7: A vehicle with a control device. Detailed description of the characters

[0037] Fig. 1 shows a side view of a first embodiment of a device 100 for tempering a component 114,126,128.

[0038] The device 100 is in Fig. 1 is shown in a sectional view from a side view and has an outer body 102, a first inlet 104, and an outlet 106. The outer body 102 is cuboid-shaped. Therefore, the sectional view only shows two surfaces that define it. The outer body has an inner wall 108, which corresponds to the inner surface of the outer body.

[0039] The first inlet 104 serves to admit a temperature control medium 118 into the outer body, which can exit again through the outlet 106. A flow direction can be defined from the first inlet 104 to the outlet 106.

[0040] Furthermore, the device 100 has an inner body 110, which is designed as a hollow body closed on one side. The opening of the hollow body is a second inlet 112, which faces the first inlet 104. This arrangement allows the temperature control medium 118 to penetrate the inner body 110 through the second inlet 112.

[0041] Fig. 2 shows a side view of a first embodiment of a tempering arrangement 113 with the device 100 from Fig. 1.

[0042] The temperature control arrangement 113 has an electrical component 114, whose surface 116 is in contact with the outer body 102 of the device 100. Thermal energy 117 is exchanged between the electrical component 114 and the device 100 via this contact. Depending on the temperature of the temperature control medium 118, the electrical component 114 can be cooled or heated. Electronic components such as processors or power supplies often require cooling, whereas batteries require heating more frequently in cold external temperatures to ensure optimal operating temperatures.

[0043] The device 100 in Fig. 2 shows, compared to the device 100, Fig. 1 has several spacers 120,130. These are placed in such a way that they prevent contact between the inner body 110 and at least a part of the inner wall 108 of the outer body 102. Both conical spacers 120 and pyramidal spacers 130 are used in the device 100 in Fig. 2. Both the inner body 110 and the spacers 120,130 consist in the example of Fig. 3 made of a plastic film and are firmly bonded together.

[0044] Arrows indicate how the temperature control medium 118 moves through the temperature control arrangement 113. Because the first inlet 102 faces the second inlet 112, the temperature control medium 118 penetrates the inner body 110, which has a hemispherical closure 122 at the end opposite the second inlet 112. The temperature control medium 118 continues to flow through the device 100 between the inner body 110 and the inner walls 108 of the outer body 102 before leaving the device 100 again via the outlet 106. The thermal energy 117 is absorbed or released by the temperature control medium 118, thus cooling or heating the electronic component 114.

[0045] When the temperature control medium 118 flows through the device 100, it penetrates the inner body 110 and flows between the inner body 110 and the inner walls 108. The resulting pressure difference in the outer body 102 between the second inlet and the closure 122 depends on the speed / pressure at which the temperature control medium is supplied to the first inlet 104. This pressure difference determines how much pressure is created in the inner body 110. Since the inner body is made of an elastic material, the pressure difference also determines how far the inner body 110 expands toward the inner walls 108. However, the expansion is limited by the spacers 120, 130. This ensures that the temperature control medium 118 can flow through the outer body 102.

[0046] Fig. 3 shows a front view of the temperature control arrangement 113 from Fig. 2. Using the example of Fig. 3 shows how the spacers 120,130 are arranged in the Fig. 2 are arranged in a dimension that is not visible due to the two-dimensional representation.

[0047] Gaps are provided between the spacers 120, 130 in this spatial direction to prevent the flow of the temperature control medium 118 from being blocked. Furthermore, it can be seen that the outer body 102 has four inner walls 108, which cannot be penetrated by the temperature control medium 118. The inner body 110 is integrally connected to the outer body 102 at two inner walls 108 to prevent slippage. However, the inner body 110 always has areas that are not in contact with the inner walls 108. Otherwise, the temperature control medium 118 would not reach the outlet 106.

[0048] Although in the Fig. 2 and Fig. 3, only one side of the outer body 102 is connected to the electrical component 114, it is of course possible to temperature-control at least one other component on the opposite side with the same device 100. For example, the device 100 can be used in a rack and placed between two printed circuit boards 126, both of which can be temperature-controlled by the device 100.

[0049] Fig. 4 shows a top view of the tempering arrangement 113 from Fig. 2. It can be seen in this illustration that some spacers 120,130 are designed as pyramid-shaped spacers 130, others as conical spacers 120.

[0050] Fig. 5 shows a front view of a second embodiment of a tempering arrangement 113.

[0051] In the example of Fig. 5, several inner bodies 110 are arranged within the outer body 102. They are cylindrical and connected to one another via connecting pieces 124. They are connected to two inner walls 108 by means of holding pieces 125. The material for the connecting pieces 124 and the holding pieces 125 can be selected such that the inner bodies 110 slip as little as possible and maintain their position as soon as the temperature control medium 118 flows through the outer body 102.

[0052] Fig. 6 shows a side view of a third embodiment of a tempering arrangement 113.

[0053] In the example of Fig. 6 is a printed circuit board 126 with a connector 128 and a multitude of electronic components 114, such as processors, electronic control units (ECUs), electrical resistors, and the like, mounted on both sides. These components generate a high level of waste heat during operation and therefore require cooling.

[0054] For this purpose, the device 100 is designed accordingly. The first inlet 104 and the outlet 106 are made of a rigid material. This allows them to be reliably connected to other components, for example, to an inlet or outlet in the form of a hose.

[0055] The remainder of the outer body 102 is made of a flexible material, such as a plastic film, and is designed in the shape of a bag. This allows the device 100 to be arranged in a contact-locking manner on both sides of the circuit board 126 (in Fig. 6 (indicated by the curved arrow). Due to the flexibility of the outer body 102, it adapts to structural differences of the component to be cooled. Manufacturing-related tolerances are also compensated in this way.

[0056] Furthermore, the inner body 110 is arranged within the outer body 102. This has a second inlet 112, which faces the first inlet 104. The second inlet 112 is also made of a rigid material to achieve a certain rigidity that facilitates the entry of the temperature control medium 118. The term "facing" does not necessarily mean that the inlets 104, 112 are aligned parallel. Rather, the second inlet 112 faces the first inlet 104 along the flow direction of the temperature control medium 118. The inner body 110 is only open on one side by the second inlet 112 and closed by a closure 122.

[0057] Conical spacers 120 are arranged integrally on the inner body 110 in such a way that they ensure a distance between the inner body 110 and the inner walls 108 of the outer body 102. This is necessary to ensure an unhindered flow of the temperature control medium 118.

[0058] When the temperature control medium 118 is admitted into the outer body 102 via the first inlet 104, it also fills the inner body via the second inlet 112. This expands due to the hydrostatic effect. Maximum expansion without clogging the outer body 102 is guaranteed by the spacers 120. A defined guidance of the temperature control medium 118 is established between the inner body 110 and the inner walls 108 of the outer body 102.

[0059] Thus, device 100 allows for flexible throttling of the flow cross-section. Furthermore, pressure loss is essentially limited to the area to be cooled. Furthermore, flow compensation is achieved even with large manufacturing deviations, and a uniform cooling contact pressure is also achieved on the outlet side.

[0060] Fig. 7 shows a vehicle 132 with a control device 138.

[0061] The vehicle 132 has a central control device 138, for example, an HPC (high-performance computer). Furthermore, the vehicle has various actuators 134, ultrasonic sensors 136, a radar sensor 140, a lidar sensor 142, and a camera 144.

[0062] The data from the various sensors 136, 140, 142, and 144 are processed in the control unit 138 and used to perform various vehicle functions. For example, parking assistance can be provided or an environmental model can be calculated, based on which the execution of automated driving maneuvers is planned.

[0063] The control device 138 is tempered by a device 100 according to the invention, since a lot of waste heat is generated due to the high computing effort.
