Description

Technical Field

[0001] The present invention relates to a cooling component for cooling an object and a method for manufacturing such a cooling component, the cooling component having at least one preferably coated metal profile that forms a heat sink. Background Technology

[0002] Cooling components used to remove heat from an object being cooled are also known as heat exchangers and are widely used in numerous technical fields. Such cooling components are particularly important in applications such as cooling batteries or battery systems in electric vehicles, and cooling power electronic components, buses, or processor chips. These cooling components are often part of a higher-level cooling system that ensures a continuous flow of a cooling medium, such as water, through them. These cooling components typically require special customization based on the application, resulting in higher costs.

[0003] The cooling body of such cooling components is typically in close contact with, but at least in proximity to, the object being cooled. Therefore, they are usually made of individual components of metal or metal alloy, such as steel, welded or brazed together in a complex manner. The connecting parts for attaching to the radiator to deliver and / or drain the cooling medium are typically made of the same metal or metal alloy as the radiator and are welded or brazed to it in a complex manner. However, since such connecting parts are not typically intended to transfer heat directly from the object to the cooling component, it is practically unnecessary to use highly thermally conductive metals to manufacture these parts. Functionally, doing so would even be counterproductive.

[0004] US Patent 2023 / 0006281 A1 discloses a thermal management system for an electrical component, the system including a housing for accommodating the electrical component and a heat exchange plate extending above a surface on the side of the housing. The heat exchange plate has a liquid passage located between a liquid inlet and a liquid outlet, a liquid inlet passage and a liquid outlet passage for supplying liquid to the heat exchange plate, and a housing that defines the housing and accommodates the heat exchange plate and the liquid outlet passage, respectively. DE 10 2007 003920 A1 relates to a liquid cooler for one or more electrical or electronic components, the liquid cooler comprising: a lower cooling plate on which one or more components to be cooled may be disposed, and a coolant channel formed on the upper side of the lower cooling plate, the coolant channel being a groove and substantially parallel to the surface of the lower cooling plate; and an upper cooling plate on which one or more components to be cooled may be disposed, and a coolant channel formed on the lower side of the upper cooling plate, the coolant channel being a groove and substantially parallel to the surface of the upper cooling plate and preferably formed in a mirror manner consistent with the coolant channel in the lower cooling plate, implemented by forming at least one inlet hole and at least one outlet hole for coolant along the normal direction of the surface of the cooling plate on the upper or lower cooling plate, the at least one inlet hole and at least one outlet hole being fluidly connected to the coolant channel. Summary of the Invention

[0005] The object of the present invention is to further develop the above-mentioned cooling component and to provide a method for producing such a further developed cooling component.

[0006] This objective is achieved by a cooling component for cooling an object, comprising at least a metal profile forming a heat sink, wherein the profile has a plurality of parallel medium channels for the flow of a cooling medium, each channel being defined by a circumferential medium channel wall formed by the profile. The cooling component further comprises a first connecting portion made of plastic, which is fluid-tightly connected to the profile and has inlets and / or outlets through which the cooling medium can be introduced into and / or discharged from the cooling component. At least one parallel medium channel has a through-hole in the circumferential medium channel wall within a region of the first connecting portion, the through-hole allowing fluid communication between the medium channel and the inlet and / or outlet of the first connecting portion. The profile has an outer side of a first large surface and an outer side of a second large surface spaced apart from the outer side of the first large surface, wherein said or each through-hole disposed in the region of the first connecting portion is disposed on the outer side of either the first or second large surface of the profile.

[0007] Furthermore, the present invention also achieves this objective through a method for manufacturing a cooling component, the cooling component having at least one metal profile forming a heat sink, and a plurality of parallel medium channels for the flow of a cooling medium, each medium channel being laterally defined by a circumferential medium channel wall formed by the profile. The cooling component also has a first connecting portion made of plastic, the first connecting portion being fluid-tightly connected to the profile, and having inlets and / or outlets through which the cooling medium can enter and / or exit the cooling component. Wherein, the circumferential medium channel wall of at least one parallel medium channel has a through-hole in the region of the first connecting portion, the medium channel being fluidly connected to the inlet and / or outlet of the first connecting portion through the through-hole, wherein the profile has an outer side of a first large surface and an outer side of a second large surface spaced apart from the outer side of the first large surface, wherein said or each through-hole arranged in the region of the first connecting portion is arranged on the outer side of the first large surface or the outer side of the second large surface of the profile. The method includes the following steps: a) Introduce through holes in a prefabricated metal profile having a medium channel and a medium channel wall, wherein the through holes are in the form of gaps introduced into the circumferential medium channel wall; b) Seal the prefabricated plastic connection to the inlet and / or outlet fluid seal in the area of ​​the through hole.

[0008] According to the invention, a cooling component for cooling an object comprises a metal profile having at least one preferably coated metal profile forming a heat sink, preferably an extruded or molded profile, for example, an extruded or molded profile, particularly made of aluminum. The elongated profile has a plurality of parallel, particularly elongated, medium channels for the flow of a cooling medium, each channel being laterally defined by a circumferential medium channel wall, the cross-section of which is particularly rectangular or approximately annular, and formed by the profile. The profile is fluid-tightly connected to a first connecting portion made of plastic, the first connecting portion having an inlet and / or an outlet through which the cooling medium can be fed into the cooling component, preferably via the inlet, and / or discharged from the cooling component, preferably via the outlet. In the region of the first connecting portion, at least one circumferential medium channel wall of the parallel medium channels, preferably one or all of the circumferential medium channel walls, is provided with through holes, which are preferably introduced by a manufacturing method such as separation or molding, through which the medium channels are fluidly connected to the inlet or outlet of the first connecting portion, respectively. According to the present invention, the through hole is a gap introduced into the wall of the circumferential medium channel.

[0009] In this invention, the term "separately" is used to identify an embodiment of a feature, which may be used additionally or alternatively. In particular, "separately" should be understood as "and / or".

[0010] According to the present invention, the method for manufacturing the cooling component, and particularly the cooling component, comprises the following steps: a) In particular, through-holes are introduced into a prefabricated metal profile having a medium channel and a medium channel wall by means of separation and / or forming methods, such as drilling, punching, pressing and / or bending, preferably using lasers, drilling devices, punching devices, pressing devices and / or bending devices, wherein the through-holes are in the form of gaps introduced into the circumferential medium channel wall. b) In particular, by preferably using heat to heat and melt the connecting surfaces of the connecting parts, the connecting surfaces of the connecting parts are compressed to the connecting surfaces of the profile, thereby sealing the prefabricated, especially injection-molded, plastic connecting parts with the inlet and / or outlet fluids in the through-hole area.

[0011] On the one hand, the present invention uses at least one metal profile, which may be made of coated metal or metal alloy, and at least one plastic connecting part. Since standardized and mature metal profile production processes, especially extrusion processes, can be used, such cooling components can be produced economically and efficiently.

[0012] On the one hand, the present invention is more cost-effective in using plastic connecting parts than in using metal or metal alloy connecting parts; on the other hand, the relatively low thermal conductivity of plastic has a functional advantage in this regard, for example, it can prevent unnecessary heat transfer to the cooling medium in the connecting part area.

[0013] Finally, according to the present invention, by simply introducing different through holes in the profile, cooling components suitable for different application scenarios, such as size, shape, profile, and arrangement, can be produced, and profiles similar in other aspects can be used.

[0014] For the purposes of this invention, the exemplary enumeration should not be considered exhaustive, but may be supplemented based on common sense.

[0015] The present invention also allows for the configuration of different cooling components, because different plastic connecting parts can be used for profiles that are otherwise similar, and these profiles can even have the same through holes.

[0016] According to a first further development of the invention, the parallel medium channels can be closed at their opposite ends. Specifically, the opposing sections of the circumferential medium channel walls of the respective medium channels are connected to each other in a fluid-tight manner. Preferably, this connection is made in a non-form-fit manner and / or by material-to-material bonding, particularly preferably by compression and / or welding of the opposing portions.

[0017] Regarding through-holes, the circumferential media channel walls of an adjacent set of media channels can form a common, continuous profile opening, which extends laterally into the media channels. For example, for an approximately cuboid profile with parallel media channels extending longitudinally, the upper wall sections of the circumferential media channel walls can be located in the same plane, thus collectively forming the upper profile wall that forms the outer side of the first large surface of the cuboid profile; while the lower wall sections of the circumferential media channel walls located in the same plane collectively form the lower profile wall that forms the outer side of the second large surface of the profile. In this case, the profile opening and / or through-hole can be an opening located on the upper or lower profile wall, transverse to the longitudinal extension direction of the media channels, thus simultaneously forming or creating each through-hole on the upper media channel wall. Therefore, the through-holes on this set of media channel walls are not spaced apart from each other, but are interconnected.

[0018] Alternatively, it can be envisioned that through-holes on the circumferential media channel walls of a group of adjacent media channels of the profile are preferably separated from each other by a parallel mesh of material formed by the profile, especially the circumferential media channel walls. In the example of the above-described approximately cuboid profile, the through-holes may, for example, be parallel grooves located on the upper or lower profile wall of the circumferential media channel wall or on the upper or lower wall segment of a wall segment located on the same plane.

[0019] Therefore, not only can the wall segments of the medium channel wall be preferably arranged on the same plane, but in general, the through holes on the circumferential medium channel wall of a group of adjacent medium channels of the profile can also be arranged on the same plane, especially on an unbent plane.

[0020] Furthermore, it can be further applied to several or all media channels of a profile, wherein the circumferential media channel wall of each adjacent media channel can have a common wall segment disposed between them, and preferably extends from one end of the profile to the other end of the profile, and each adjacent media channel is adjacent to the common wall segment.

[0021] This allows for the following: a common wall segment of the circumferential media channel walls of two adjacent media channels is interrupted in at least one region, particularly at least one end region of the adjacent media channels, or is provided with a connecting opening, allowing cooling medium to flow from one media channel to the other. This also correctly achieves the following: outside the region of wall segment interruption or each region, or outside the connecting opening or each connecting opening, the common wall segment fluid-tightly separates the two adjacent media channels from each other, thereby preventing cooling medium from flowing from one media channel to the other.

[0022] The aforementioned interruption or connection opening allows for direct connection of the media channels. For example, cooling media can only flow through a media channel if one of two adjacent media channels, or its designated circumferential media channel wall, has a through-hole in the first end region of the profile, allowing the cooling medium to be introduced through the connection portion via this through-hole. The cooling medium then flows directly through the connection opening or interruption to another media channel located in the second end region, without requiring a through-hole fluidly connected to one of the media channels or the connection portion. Subsequently, the cooling medium can be further directed to another media channel, particularly back to the first end. Based on this concept—utilizing connection openings between adjacent media channels—it is clear that this concept can also be applied to two or more media channels adjacent in this manner, and various different schemes can be conceived for designing and selectively controlling the flow of cooling media in cooling components. Advantageously, control of individual channels can be achieved, thereby selectively guiding the cooling medium flow through each media channel.

[0023] It can also be further provided that, in each case, the parallel first subgroup of media channels has a through-hole through which each cooling channel is fluidly connected to the inlet or outlet of the first connecting portion; in each case, the second subgroup of media channels has a through-hole through which each cooling channel is selectively non-fluidly connected to the inlet or outlet of the first connecting portion, but the through-hole is fluid-tightly isolated from the outside, particularly through the first connecting portion.

[0024] For example, this can be achieved by a suitable wall in the connection that covers the through-hole after the connection is fluid-sealed to the profile, thereby preventing the cooling medium from flowing through the through-hole. Alternatively, a "closed cavity" can be envisioned, in which the cooling medium can actually flow through the through-hole, but the closed cavity is isolated from the outside, especially from the inlet or outlet of the connection.

[0025] For example, certain through holes in a profile that are not used for a specific application can be sealed by using connecting parts of a corresponding shape, thus ensuring their closure. In other words, when using a specific profile with a medium channel, connecting parts for selectively sealing specific through holes can be pre-selected during the assembly of the cooling components. Certain through holes have been pre-introduced or arranged on the circumferential wall of the medium channel.

[0026] Exemplary independent channel control can guide the cooling medium from the inlet of the connector to one or more selected medium channels. The medium can then be diverted to other medium channels via the connector. The diversion of the cooling medium can also occur directly within the connector, allowing the medium to flow in preset channels and ultimately be guided to the outlet.

[0027] In an exemplary design, the connection portion and connector may have a flow-diverting space to allow the cooling medium to flow between different medium channels. Within this flow-diverting space, the cooling medium is selectively diverted from one medium channel to another, preferably adjacent medium channels. This allows the cooling medium to flow flexibly and controllably through the different medium channels of the cooling component.

[0028] Optionally, the connecting portion and connector can be designed without a flow split. Instead, exemplary interruptions can be provided on the walls of the media channels. As described above, the common wall segment of the circumferential media channel walls of two adjacent media channels can be interrupted in at least one region, particularly at least one end region of the adjacent media channels, or can have a connecting opening allowing cooling medium to flow from one media channel to another. This connecting opening allows cooling medium to flow directly from one media channel into an adjacent media channel. In this case, the connecting portion and connector seal the opening of the media channel relative to the outside, while the cooling medium can flow through the connecting opening between the media channels.

[0029] Similarly, these two approaches can be combined by using both diversion spaces and connection openings on the channel walls. The advantage of this is that the cooling performance and flow path of the cooling medium can be more flexibly and precisely adapted to specific cooling needs. Therefore, through independent channel control, the cooling medium can be precisely controlled according to the expected heat dissipation of the component to be cooled, such as a battery.

[0030] Regarding the profile, a one-piece molding process is typically employed. According to the invention, the profile has a first large surface, particularly a flat, curved, or corrugated outer side; a first and second large surface, spaced apart from and particularly parallel to the first large surface, particularly a flat, curved, or corrugated outer side; and preferably two spaced apart from and connected to each other the outer sides of the first and second large surfaces, particularly flat, curved, or corrugated narrow outer sides.

[0031] Furthermore, each or every through hole arranged in the first connection portion region may be arranged on the outer side of the first or second large surface of the profile.

[0032] According to the present invention, the or each through hole arranged in the first connecting portion region is arranged in the first end region of the profile, particularly maintaining a certain distance from the first end. Optionally, the or each through hole arranged in the first connecting portion and the first connecting portion region may also be arranged in the central region of the profile.

[0033] The first connecting portion may further have an inlet cavity, which includes an inlet through which a through-hole in the circumferential medium channel wall of an optional corresponding medium channel opens, and the medium channel is fluidly connected to the inlet through the through-hole. In one design, the inlet cavity includes multiple chamber portions, preferably at least two chamber portions, which communicate with each other. Optionally or additionally, the first connecting portion may further have an outlet cavity, which is particularly separated from the inlet cavity and includes an outlet through which a through-hole in the circumferential medium channel wall of an optional corresponding medium channel opens, and the medium channel is fluidly connected to the outlet through the through-hole. In one design, the outlet cavity includes multiple chamber portions, preferably at least two chamber portions, which communicate with each other. Optionally or additionally, the first connecting portion includes a diversion space through which the cooling medium can preferably be diverted from at least one first medium channel to at least one second medium channel.

[0034] Regarding the circumferential media channel walls of the optional media channels, preferably, regarding the circumferential media channel walls of multiple or all media channels, they may therefore have additional through holes in the area of ​​the second connecting portion made of plastic, which are fluidly connected to the profile. In particular, gaps are introduced in the circumferential media channel walls through which the media channels are fluidly connected to the inlet or outlet of the additional connecting portion.

[0035] The circumferential media channel walls of each optional media channel, preferably the circumferential media channel walls of multiple or all media channels, may also have another through-hole in the plastic connector area. This connector is fluid-tightly connected to the profile, particularly for distributing cooling media, and the media channels are fluidly connected to the connector's internal space via this through-hole. The internal space is in turn fluidly connected to at least one other parallel media channel via a through-hole in the circumferential media channel wall of another media channel within the connector area. Optionally or additionally, the connector includes a distribution space through which cooling media can preferably be diverted from at least one first media channel to at least one second media channel.

[0036] Therefore, the second connecting portion or connector, and each of the through holes respectively disposed in the area of ​​the second connecting portion or connector, can be arranged at the second end of the profile, in the area opposite to the first end, at a certain distance from the second end. Optionally, the second connecting portion can also be disposed together with the first connecting portion in the central area of ​​the profile.

[0037] It is also conceivable that the first connecting portion and / or the second connecting portion and / or the connector, particularly one or more of its walls, are formed in such a way that the first connecting portion and / or the second connecting portion and / or the connector separates at least one media channel from the inlet or outlet of the first connecting portion or the second connecting portion, or from the internal space of the connector, such that no cooling medium can flow between the through-hole on one side and the inlet or outlet of the other side, or between the through-hole and the internal space of the connector. This is particularly suitable for media channels having through-holes, which are preferably introduced into the circumferential media channel wall located in the region of the first connecting portion, the second connecting portion, or the connector by means of separation and / or molding.

[0038] By forming corresponding connecting parts and / or connectors, or using connecting parts / connectors of different shapes, the media channels present in the corresponding profile can be selectively controlled. These media channel walls have through holes, representing channels actually used in a specific application, as well as unused channels. For example, for media channels not needed in a specific application, the media channel walls with through holes in the specially prefabricated profile can be locked or closed by the corresponding walls of the locking through holes of the connecting parts and / or connectors, thus preventing cooling media from flowing through the through holes.

[0039] Based on this concept of selectively forming corresponding connection parts or connectors, a variety of different schemes can be envisioned to design and selectively control the flow of cooling medium in cooling components.

[0040] Similarly, the first connecting portion and / or the second connecting portion and / or the connector, especially one or more walls of the first connecting portion and / or the second connecting portion and / or the connector, can be formed in such a way that, on the one hand, the first connecting portion and / or the second connecting portion and / or the connector, especially one or more walls of the first connecting portion and / or the second connecting portion and / or the connector, effectively separate at least two particularly adjacent medium channels, each medium channel having a through-hole on the circumferential medium channel wall of the first connecting portion or the second connecting portion or the connector's internal space from the through-holes on the circumferential medium channel walls of the other medium channels, so that no cooling medium flows between the through-hole on the circumferential medium channel wall of the particularly adjacent medium channel on one side and the inlet or outlet cavity or the internal space of the other side, but on the other hand, the through-hole forms a fluid connection channel between the medium channels.

[0041] For example, the connecting portion / connector or its corresponding wall can be formed in such a way that through holes in the circumferential medium channel walls of the two medium channels of the profile respectively lead into the connecting channel, which is defined or arranged at the walls of the connecting portion / connector and optional profile, so that the cooling medium can flow from the through hole in the circumferential medium channel wall of one medium channel into the connecting channel, then flow in the connecting channel to the through hole in the circumferential medium channel wall of the other medium channel, and finally flow into the other medium channel through the through hole.

[0042] For example, if one of the media channels, or its designated circumferential media channel wall, has a through-hole in the first end region of the profile, the cooling medium can be introduced through this through-hole via a connecting portion. After being introduced, the cooling medium can flow through this media channel, then through the connecting channel to another media channel located in the second end region, and finally be introduced into another media channel, specifically returning to the first end. Based on this fundamental concept, especially the formation and use of connecting channels between media channels, it is clear that this concept can also be applied to a group of two or more media channels, and various different schemes can be envisioned for designing and selectively controlling the flow of cooling medium in cooling components.

[0043] In particular, but not limited to this, for example, a connecting channel can be provided for two adjacent medium channels, each of which has a wall segment and / or a common wall segment in its circumferential medium channel wall, the common wall segment being located between the two adjacent medium channels, and as described above, the common wall segment extending particularly from one end of the profile to the other end of the profile.

Detailed Implementation

[0045] The figure shows a cooling component 10, which, for example, serves as a component for cooling the battery or battery system of an electric vehicle, to cool the respective battery or individual cell. In this example, battery 25 is shown in an exemplary manner.

[0046] Such a cooling component 10 is therefore typically part of a higher-level cooling system that ensures a continuous flow of cooling medium through the cooling component 10, thereby absorbing waste heat from the object to be cooled and dissipating that waste heat. Components required for the cooling system, such as suitable pumps and inlet / outlet piping for the cooling medium, are known in the prior art and will not be described further.

[0047] In this example, cooling component 10 can be connected to other identical cooling components (not shown) of the cooling device during use, and multiple objects to be cooled, such as multiple batteries or cells, can be cooled simultaneously.

[0048] The cooling component 10 has a metal profile 11 that forms a heat sink, which in this example is made of aluminum. In use, the profile is in close contact with, or at least directly adjacent to, the object to be cooled. In this example, the profile 11 is integrally formed using an aluminum extrusion process, and is therefore an extruded profile. The metal profile or extruded profile itself may also be made of other metal materials.

[0049] Profile 11 is slender and elongated, and in this example it is basically a flat cuboid.

[0050] Based on the main extension direction of the cooling component 10 or the profile 11, a connecting portion 12 made of plastic is provided at its end 17a region, through which a cooling medium, such as cooling water, can be introduced into the cooling component 10. The cooling medium is then guided into a first set of elongated medium channels 14a, flowing either along the main extension direction of the profile 11 or longitudinally to the other end 17b of the profile 11. Afterward, the cooling medium is split in a connector 13 located at the other end 17b region, flowing in the opposite direction through the radiator of the cooling component 10, then in the opposite direction through a second set of elongated medium channels 14b, and finally reaching the connecting portion 12 again, where it is either guided out or discharged from the cooling component 10.

[0051] During operation of the cooling device or cooling component 10, as the cooling medium flows through the profile 11 or through the medium channel 14, it absorbs the waste heat generated by the object to be cooled, which is the battery 25 in this case, thereby cooling the object to be cooled and dissipating the waste heat.

[0052] In this example, the profile 11 has four outer walls 15, namely a first large surface upper wall 15a, a second large surface lower wall 15b parallel to the upper wall and maintaining a certain distance, and two parallel narrow side walls 15c or 15d, which connect the upper wall 15a and the lower wall 15b to each other respectively.

[0053] Elongated media channels 14 are arranged inside the profile 11, that is, inside the space enclosed by the outer wall 15 of the profile. The media channels 14 extend parallel to the main extension direction of the profile 11 or parallel to the narrow sidewalls 15c or 15d. Based on the cross-section of the profile 11, the media channels 14 are arranged side by side in a row.

[0054] Based on the main extension direction of the corresponding medium channel 14, each elongated medium channel 14 is further defined by a circumferential medium channel wall 16, which is formed by the profile 11 on preferably all its longitudinal sides. The circumferential medium channel wall 16 thus forms a hollow cuboid, or a rectangle in cross-section, wherein, in this application, a cuboid is defined as a special case of a rectangle.

[0055] In this example, each circumferential medium channel wall 16 specifically includes two pairs of wall segments, each pair of wall segments being opposite to each other and maintaining a certain distance between them.

[0056] On one hand, each medium channel 14 is thus defined on two opposing longitudinal sides by two sidewall segments 16a or 16b, which are perpendicular to the upper and lower large surface walls 15a or 15b, respectively, i.e., along the transverse or perpendicular direction of the main extension of the profile 11. These two sidewall segments 16a or 16b are parallel to each other along the main extension direction of the profile 11 and are spaced apart from each other. For the two outer medium channels 14, one of the medium channel walls 16a or 16b is formed by a corresponding outer wall 15 of the profile 11, which in this example is formed by a narrow sidewall 15c or a narrow sidewall 15d.

[0057] On the other hand, the other two longitudinal sides of each elongated medium channel 14 are defined by an upper wall section 16a and a lower wall section 16b. The upper wall section 16a is formed by a portion of the upper large surface wall 15a of the profile 11, and the lower wall section 16b is formed by a portion of the lower large surface wall 15b.

[0058] Furthermore, in this example, each medium channel 14 is not open at both ends, but is closed in a fluid-tight manner at the two opposite profile ends 17a and 17b. During the manufacturing process of the cooling component 10, the wall segments 16a and 16b of the corresponding circumferential medium channel wall 16 of each medium channel 14 of the profile 11 are initially opposite each other and a certain distance apart. For this purpose, they are brought closer together by corresponding clamping devices and connected together in a fluid-tight manner, that is, in this example, a weld is formed by compression, followed by welding or brazing.

[0059] Regarding the connecting part 12, it is provided with an inlet 18, and the inlet 18 is provided with an entrance 19. The cooling medium can be sent into the cooling component 10 through the entrance 19, and then enter the first group 14a medium channel 14. The connecting part 12 is also provided with an outlet 20, which is separated from the inlet 18. The outlet 21 is used to discharge the cooling medium from the medium channel 14 of the second group 14b medium channel, especially from the connecting part 12 or the cooling component 10.

[0060] In this example, the circumferential medium channel wall 16 of each medium channel 14, i.e., the upper wall segment 16a of each channel wall in this example, has a through hole 22 in the region of the connecting portion 12, i.e., the region of the first end 17a of the profile 11 in this example. Each medium channel 14 is fluidly connected to the inlet 19 or outlet 21 of the connecting portion 12 through the through hole 22. The through hole can be a gap, for example, formed by drilling tools or lasers.

[0061] As shown in the figure, in this example, the through holes 22 of the circumferential medium channel wall 16 are interconnected in the transverse direction of the profile 11 without any gaps between them, thus forming a common, continuous profile opening 23, which extends laterally to the medium channel 14 on the outer wall 15a of the large surface of the profile 11. However, this is not necessary, and the through holes may also be spaced apart from each other.

[0062] The connecting portion 12 is disposed on the upper wall 15a of the profile 11, such that the inlet cavity 18 and the outlet cavity 20 respectively cover the corresponding through hole 22 of the medium channel 14 for fluid connection, or the through hole 22 respectively leads to the inlet cavity 18 or the outlet cavity 20.

[0063] Specifically, the through hole 22 of the first group 14a medium channel 14 is provided in the inlet cavity 18, so that the cooling medium can flow directly from the inlet cavity 18 and / or flow into the first group 14a medium channel 14 via the through hole 22; at the same time, the second group 14b medium channel 14 is provided, so that the cooling medium can flow from the outlet cavity 20 through the through hole and / or flow into the second group 14b medium channel 14 via the through hole 22.

[0064] Regarding connector 13, the through holes 22, in this example forming continuous profile openings 23, are also respectively provided in the circumferential medium channel wall 16 of the medium channel 14, i.e., each upper wall segment 16a, in the connector region, i.e., the region of the second profile end 17b. In this embodiment, all the through holes 22 are covered by the diversion space 24, or the through holes 22 respectively lead to the diversion space.

[0065] The cooling medium flows into the diversion space 24 from the through hole 22 of the first group 14a medium channel 14, is diverted in the diversion space 24 to the through hole 22 of the second group 14b medium channel 14, flows back into the second group 14b medium channel 14, and then returns to the connecting part 12 via the profile 11 in the second group 14b medium channel 14.

[0066] As described above, unlike profile 11, connecting portion 12 and connector 13 are not made of metal or metal alloy, but of plastic. In this example, all components are integrally molded and manufactured using injection molding processes, for example, using thermoplastic plastics.

[0067] To connect the connecting portion 12 and the connector 13 to the profile 11, their connecting areas or connecting surfaces are respectively connected to the connecting areas or connecting surfaces of the profile 11 in a fluid-tight manner.

[0068] In this example, the connecting surface of the metal profile 11 has a three-dimensional nanostructure and / or microstructure, which are introduced into the corresponding surface by physical and / or chemical nanostructuring or microstructuring methods, such as chemical etching or laser beam structuring.

[0069] Each connecting surface of the profile 11 is structured in the manner described above so as to be opposite to and connected to a designated connecting surface of the connecting portion 12 or the connector 13, for example by compression connection via thermal connection, which will be described in detail below.

[0070] The specific production of the cooling component 10, especially the connection between the aforementioned metal cooling component 10 and the plastic connecting part 12 and the plastic connector 13, is carried out in a special manner.

[0071] Profile 11, connecting part 12 and connector 13 are first prefabricated, and in this example, they are respectively processed by extrusion molding or injection molding.

[0072] Then, through holes 22 are formed in the profile 11 by suitable manufacturing methods, such as separation and / or forming. For example, drilling can be performed using suitable drilling tools, such as mechanical drilling tools, or processing can be performed using a laser. The profile material can also be punched and / or bent and / or pressed, preferably by punching, bending and / or pressing devices.

[0073] As described in detail above, the initial cuboid ends 17a and 17b of the profile 11 are further compressed by closing the ends of the previously open media channel 14 on the front side of the profile 11, thereby forming welds respectively. The welds are then welded or brazed to ensure fluid tightness.

[0074] The aforementioned components 11, 12, and 13 are typically then connected to each other; however, the order of different steps can be changed. The following explanation will take the connection between the connecting part 12 and the profile 11 as an example. The connection method between the profile 11 and the connecting part 12 is similar.

[0075] To connect the profile 11 and the connecting portion 12, the two components are first moved relative to each other and aligned. For example, the connecting portion 12 remains stationary while the profile 11 moves along the direction of the connecting portion 12 via a suitable conveying member. Of course, the process can also be reversed, or the two components can move towards each other.

[0076] During the aforementioned relative motion, the profile 11 moves relative to the connecting portion 12, so that the connecting surfaces of the profile 11 are precisely fitted together, thereby ensuring that each connecting surface of the profile 11 is opposite to a designated connecting surface of the connecting portion 12.

[0077] Subsequently, during and / or before this period, the metal profile 11, at least the connecting surface 26 of the profile 11, is heated to a temperature corresponding at least to the softening temperature of the plastic of the connecting portion 12, in particular an induction heater known in the prior art, but obviously other heating techniques may also be used.

[0078] Then, the heat from the profile 11 is transferred to the connecting portion 12 or its connecting surface, causing the connecting surface to melt.

[0079] The various connecting surfaces are then pressed together to form a fluid-tight connection, for example by a corresponding clamping member, such as a clamping jaw not shown in the figure, which presses against the wall of the connecting portion 12 to be connected from the outside. This can be understood as a direct thermal connection.

[0080] Figure 8 Another design for the cooling component 10 with independent channel control is shown. The cooling component 10 includes a metal profile 11 forming a heat sink, which is preferably made of a material similar to... Figure 2 The profile 11 is extruded in the same manner as described above. A connecting portion 12, made of plastic, is arranged in the region of the first end 17a. The connecting portion includes an inlet chamber 18 through which cooling medium can be delivered into the cooling component 10. The connecting portion 12 also includes an outlet chamber 20 through which coolant can be discharged from the cooling component 10. The second end 17b of the profile 11 includes a connector 13 through which coolant can be discharged. Figure 11 The media channels 14 shown are split into channels with individual channel control.

[0081] Figure 9 Showing according to Figure 8 An exploded view of an embodiment. The profile 11 of the heat sink 10 includes a plurality of through holes 22, wherein two through holes 22 of each medium channel 14 are respectively disposed on both ends 17a and 17b of the profile 11. The through holes 22.1 and 22.2 of the first group 14a medium channel 14 and the through holes 22.25 and 22.26 of the second group 14b medium channel 14 are in Figure 9 The vias 22 of the upper medium channel wall 16a are spaced apart from each other and are not connected. Since each medium channel 14 has exactly one opening at each end 17a and 17b, the cooling medium of the medium channel 14 can be individually controlled by the correspondingly formed connecting portion 12 and connector 13. Thus, the adjustment of the cooling component 10 can advantageously accommodate, for example, the expected heat dissipation of the battery 25.

[0082] The through hole 22 on one end 17a of the profile 11 is completely covered by the connecting portion 12. The connecting portion 12 has an inlet cavity 18, on which an upper inlet 19 is provided. The inlet cavity 18 extends above the two sets of channels 14a and 14b of the medium channel 14. The connecting portion 12 also has an outlet cavity 20, on which an outlet 21 is provided. The outlet cavity 20 also extends above the two sets of channels 14a and 14b of the medium channel 14. Figure 11 As shown, the through hole 22 is arranged on the first end 17a, such that the through hole 22 is covered by the inlet cavity 18, the outlet cavity 20 and the diversion space.

[0083] Figure 9 It is also shown that the through hole 22 on the second end 17 of the profile 11 is completely covered by the connector 13.

[0084] Figure 10 Showing according to Figure 8 A further exploded view of the cooling component 10. A perspective view of the cooling component 10 from the bottom can be shown. The connecting portion 12 includes an inlet cavity 18, the portion 18.1 of which is visible here. The outlet cavity 18.2 is covered by the profile 11. Figure 11 As can be seen in the image. The connecting portion 12 further includes an outlet 20, the portion 20.1 of which is visible here. The outlet 20.2 is covered by the profile 11. Figure 11 As can be seen here. The connecting portion 12 also includes a branching space, whose branching space 24.3 is visible here. Further branching spaces of the connecting portion 12 are... Figure 11 As can be seen in the text.

[0085] Figure 10 It is also shown that connector 13 includes shunt spaces 24.1, 24.2, 24.4, 24.5, 24.7, 24.9, 24.10, 24.11, 24.13 and 24.14. Figure 11 The various media channels 14 shown lead to these diversion spaces so as to divert the cooling medium to other media channels 14.

[0086] Figure 11 A top view of the cooling component 10 is shown, in which the connecting portion 12 and the connector 13 are longitudinally cut along a plane parallel to the heat sink. The connecting portion 12 has an inlet cavity 18, which, in the cross-sectional view, is divided into two parts 18.1 and 18.2. The inlet cavity 18.1 and 18.2 are interconnected. In the cross-sectional view, the outlet cavity 20 is also divided into two parts 20.1 and 20.2. The outlet cavity 20.1 and 20.2 are interconnected.

[0087] The oral cavity 18.1 connects to different media channels 14 through through-holes 22.1, 22.5, 22.13, and 22.25. For clarity, Figure 11The medium channels 14 are not labeled with reference numerals, but are instead indicated by arrows indicating the flow direction of the cooling medium. The cooling medium is fed into the medium channel through through-hole 22.1, then into the distribution space 24.1 through through-hole 22.1, and from there into the adjacent medium channel via through-hole 22.3, finally entering the outlet cavity 20.1. The coolant, starting from the inlet cavity 18.1, is fed into the medium channel 14 through through-hole 22.5, then into the distribution space 24.2 of the connector 13 via through-hole 22.6, and from there into another medium channel 14 via through-hole 22.7. A distribution space 24.3 is provided in the connection portion 12, through which the cooling medium enters another medium channel 14 via through-hole 22.8 and through through-hole 22.9. The diversion space 24.4 then introduces the cooling medium from the through hole 22.10 through the through hole 22.11 into the adjacent medium channel 14, and finally enters the outlet cavity 20.1 through the through hole 22.12.

[0088] Cooling medium enters medium channel 14 from inlet 18.1 via through hole 22.13. The cooling medium then flows from medium channel 14 into branch space 24.5 via through hole 22.14, and from branch space 24.5 into adjacent medium channel 14 via through hole 22.15. Cooling medium enters branch space 22.6 via through hole 22.16, and from branch space 22.6 into adjacent medium channel 14 via through hole 22.17. Cooling medium is also introduced into branch space 22.7 via through hole 22.18, and from branch space 22.7 into adjacent medium channel 14 via through hole 22.19. Cooling medium enters another medium channel 14 through branch space 24.8 via through holes 22.20 and 22.21, which leads to branch space 24.9 via through hole 22.22. The cooling medium enters the medium channel from the distribution space 24.9 through the through hole 22.23, and finally enters and exits the oral cavity 20.1 through the through hole 22.24.

[0089] The cooling medium flows from the inlet cavity 18.1 further into another medium channel 14 via through hole 22.25, which in turn flows into the branch space 24.10 via through hole 22.26. The cooling medium is introduced into the medium channel 14 from the branch space 24.10 via through hole 22.27, and then returns to the outlet cavity 20.1 via through hole 22.28.

[0090] The cooling medium is introduced into the medium channel 14 from the inlet cavity 18.1 via the through hole 22.25, and then enters the branch space 24.10 from the medium channel 14 via the through hole 22.26. The cooling medium is introduced into the adjacent medium channel 14 from the branch space 24.10 via the through hole 22.27, and then enters the outlet cavity 20.1 via the through hole 22.28.

[0091] However, depending on the anticipated heat dissipation or cooling requirements, the illustrated independent channel control system can not only control each medium channel 14 individually, but also control multiple medium channels 14 simultaneously. Starting from the inlet 18.2, three medium channels 14 thus enter via through-holes 22.29, 22.30, and 22.31. The medium channels 14 flow into the distribution space 24.11 via through-holes 22.32, 22.33, and 22.34, and the cooling medium is further introduced into the other three medium channels 14 via through-holes 22.35, 22.36, and 22.37 through the distribution space 24.11. Another distribution space 24.12 in the connecting portion 12 receives the cooling medium via through-holes 22.28, 22.39, and 22.40, and introduces the cooling medium into three adjacent medium channels 14 via through-holes 22.41, 22.42, and 22.43. In the diversion space 24.13, the cooling medium is introduced into other medium channels 14 through through holes 22.44, 22.45, and 22.46, and then through through holes 22.47, 22.48, and 22.49. These medium channels 14 open into the outlet cavity 20.2 via through holes 22.50, 22.51, and 22.52. The cooling medium further flows from the inlet cavity 18.2 into the diversion space 24.14 through through holes 22.53 and 22.54, and from the diversion space 24.14 into the outlet cavity 20.2 through through holes 22.55 and 22.56.

[0092] Figure 12 An alternative design for the cooling component 10 with independent channel control is shown. The figure shows the profile 11, the connection portion 12 connecting to the inlet chamber 18 and the outlet chamber 20, and the connector 13.

[0093] Figure 13 Showing according to Figure 12 An exploded view of the cooling component 10. The profile 11 includes multiple through holes 22, wherein through holes 22.1, 22.5, 22.13, 22.25, 22.29, 22.30, 22.31, and 22.53 are respectively connected to an inlet cavity 18 (not shown in the figure). These through holes are all individually designed and connected only through the inlet cavity 18, which allows for... Figure 15 As seen in the image, through holes 22.4, 22.12, 22.24, 22.28, 22.50, 22.51, 22.52, and 22.56 are also individually designed and connected only through the outlet cavity 20. The outlet cavity 20 can also be... Figure 15As seen in the diagram. Not all of the remaining through holes 22 are indicated; for clarity, the reference numerals here specifically refer to the through holes 22 leading to the diversion space 24 in the above design. However, in this embodiment, the connecting portion 12 and the connector 13 do not contain any diversion space. Instead, the common wall segment of the circumferential media channel walls 16 of the two adjacent media channels 14 is interrupted in at least one region, as can be seen, for example, at the through hole 22.10. Cooling medium can thus flow from one media channel 14 to the other. In this design, the connector 13 seals the media channel 14 upwards in the region of the through hole 22 at the second end 17b.

[0094] Figure 14 An exploded view of the cooling component 10 from the bottom is shown. The connecting portion 12 includes two inlet chambers 18.1 and 18.2, which communicate with each other and with an inlet 19. The connecting portion 12 also includes two outlet chambers 20.1 and 20.2, which communicate with each other and with an outlet 21. The connecting portion 12 does not contain any branching space. Instead, as... Figure 13 As shown, in the region of through-hole 22, the connecting portion is designed to be flat on the side facing the profile 11, and the common wall segment of the circumferential medium channel wall 16 is interrupted in at least one region. Therefore, the connecting portion 12 can precisely seal the through-hole 22 upwards.

[0095] from Figure 14 It can be seen that connector 13 does not include any chamber or shunt space. Instead, Figure 13 All visible through-holes 22 are sealed at the end 17b near the top via connector 13. No flow splitting space is required in this embodiment because the common wall section of the circumferential medium channel wall 16 is interrupted in at least one region, allowing the cooling medium to flow between the medium channels 14 having the common medium channel wall 16.

[0096] Figure 15 Showing according to Figure 12 A top view of the cooling component 10, wherein the connecting portion 12 and the connector 13 are longitudinally cut in a plane parallel to the heat sink. The connecting portion 12 has an inlet cavity 18, which, in the cross-sectional view, is divided into two parts 18.1 and 18.2. The inlet cavities 18.1 and 18.2 are interconnected. The inlet cavities 18.1 and 18.2 lead to different medium channels 14 (not shown) through through holes 22.1, 22.5, 22.13, 22.25, 22.29, 22.30, 22.31 and 22.53.

[0097] In the sectional view, the outlet cavity 20 is also divided into two parts, 20.1 and 20.2. The outlet cavities 20.1 and 20.2 are interconnected. Each medium channel 14 leads to the outlet cavities 20.1 and 20.2 via through holes 22.4, 22.12, 22.24, 22.28, 22.50, 22.51, 22.52 and 22.56.

[0098] Neither the connection portion 12 nor the connector 13 includes a shunt space, because the cooling medium can flow between the medium channels 14 through the wall interruption.

[0099] Through this individual channel control, the cooling medium in the medium channel 14 can be advantageously controlled according to the expected heat source heat dissipation distribution.
