[0001] Fluid-conducting structural component, method for demoulding a fluid-conducting structural component produced by injection moulding, thermal management module with such a component and vehicle with such a component
[0002] The invention relates to a fluid-conducting structural component with at least one first fluid connection device and at least one second fluid connection device and at least one fluid path, wherein the at least one fluid path opens into the at least one first fluid connection device, a method for demolding such a fluid-conducting structural component produced by injection molding in an injection molding tool containing at least one injection molding tool upper part and injection molding tool lower part, a thermal management module for managing mass flows of a temperature control medium in at least one temperature control circuit of a vehicle, wherein the thermal management module comprises at least one load-bearing structural component with at least two fluid connection devices and at least one fluid path, and a vehicle with at least one temperature control circuit for temperature control of vehicle components, in particular at least one battery and at least one electronic component,wherein at least one such thermal management module is provided for managing mass flows of a temperature control medium in the at least one temperature control circuit.
[0003] Fluid-conducting structural components with a first fluid connection device and a second fluid connection device and at least one fluid path, in which the fluid path opens into the first fluid connection device, are known in the prior art. These can be used, for example, in vehicles in which fluids and other media are transported to and from vehicle components via media lines. Particularly in electric vehicles and hybrid vehicles, an increasing number of electronically controlled components, such as electrically adjustable control valves, electrically adjustable pumps, a multitude of sensors, etc., are arranged along the vehicle's fluid circuits or temperature control circuits, such as cooling circuits. This enables demand-based and driving-condition-optimized thermal management, which supports driving comfort on the one hand and optimizes the vehicle's range on the other.The temperature control medium used in each case is guided in a closed system of a vehicle's temperature control circuit. Such a temperature control circuit comprises at least a first sub-circuit, which serves to temperature control a traction battery, at least a second sub-circuit, which serves to temperature control at least one electronic component, and at least a third sub-circuit, which includes a heat exchanger, which serves to absorb heat from the ambient air of the vehicle and to release heat to it and through which the temperature control medium also flows, so that heat can be transferred through the heat exchanger into the temperature control medium and from there to the ambient air. The climate comfort for the interior or cabin of a vehicle can also be regulated via the third sub-circuit. Each of the sub-circuits has a supply line and a return line and a number of media lines through which at least one temperature control medium flows.A thermal management module can be provided to manage mass flows of the temperature control medium in such a closed temperature control circuit of a vehicle.
[0004] DE 10 2021 102473 A1 discloses a thermal management module for a cooling system for a motor vehicle with an electric drive system, which module has a module housing with a plurality of cooling fluid connections, wherein the cooling fluid connections comprise a first cooling fluid connection, a second cooling fluid connection, and a third cooling fluid connection, and a control valve arranged in the module housing is provided for controlling a fluid flow between the cooling fluid connections. The thermal management module has a first connecting line for conducting cooling fluid, wherein the first connecting line couples the first cooling fluid connection to the second cooling fluid connection in a fluid-communicating manner. An interior space is formed inside the module housing of the thermal management module, in which an control valve designed as a rotary slide valve is arranged.The control valve enables a fluid-communicating connection between the individual cooling fluid connections to be switched on and off. For this purpose, the control valve has valve chambers with valve chamber openings that can be aligned with the corresponding cooling fluid connections, allowing at least two cooling fluid connections to be fluidly connected to one another via a valve chamber. This thermal management module is thus a special valve tailored to a specific application in the form of a 9 / x directional valve for regulating the cooling medium in various branches of the highly complex and elaborate cooling system. The fluid connection devices are arranged in only one plane, so their number is limited by the dimensions of the module housing.
[0005] The present invention is based on the object of developing a fluid-conducting structural component with at least one first fluid connection device and at least one second fluid connection device and at least one fluid path, wherein the at least one fluid path opens into the at least one first fluid connection device, as well as a method for demolding such a fluid-conducting structural component produced by the injection molding process in an injection molding tool in such a way that a larger number of fluid connection devices can be provided on the fluid-conducting structural component, wherein good demolding of the fluid-conducting structural component produced by the injection molding process should still be possible.
[0006] The object is achieved for a fluid-conducting structural component according to the preamble of claim 1 in that the at least one second fluid connection device is arranged approximately perpendicular to the at least one fluid path along the latter and is in fluid communication with the fluid path, wherein the at least one second fluid connection device has at least two locking lugs provided with an undercut for forming a holding region for fastening a media line to the at least one second fluid connection device.For a method according to the preamble of claim 10, the object is achieved in that the fluid-conducting structural component is demolded at least in a first plane of the fluid-conducting structural component lying in the main extension plane of the fluid-conducting structural component, wherein at least two locking lugs of the at least one second fluid connection device are demolded from the side of their undercut through at least two through-openings between the at least one second fluid connection device, the at least one fluid path, and a structural element spaced apart from the at least one second fluid connection device. For a thermal management module according to the preamble of claim 12, the object is achieved in that the at least one load-bearing structural component is the fluid-conducting structural component defined above or comprises it.For a vehicle according to the preamble of claim 13, the object is achieved in that the at least one thermal management module is such a thermal management module. Further developments of the invention are defined in the dependent claims.
[0007] This creates a fluid-conducting structural component with at least one fluid path, in particular a fluid channel, wherein at least one first fluid connection device can be or is arranged at the end of the at least one fluid path, in particular a fluid channel, of the fluid-conducting structural component. Furthermore, at least one second fluid connection device is arranged along the at least one fluid path, in particular a fluid channel. This is arranged approximately perpendicular, in particular exactly perpendicular, to the longitudinal axis of the at least one fluid path, in particular a fluid channel. This makes it possible to provide a larger number of fluid connection devices on the fluid-conducting structural component, since not only first fluid connection devices can be arranged in one plane, but also at least one second fluid connection device can be arranged in a plane perpendicular thereto on the fluid-conducting structural component.
[0008] The at least one first fluid connection device, which is arranged in the main extension plane of the fluid-conducting structural component at the end of the at least one fluid path, in particular a fluid channel, can have a circumferential retaining collar for locking and holding a holding element for fastening a line connector of a media line to be connected there. The fluid-conducting structural component is preferably made of a material that can be processed using an injection molding process, such as at least one plastic material. Demolding of the fluid-conducting structural component produced using the injection molding process is made possible in the region of the at least one second fluid connection device in that the at least two locking lugs provided with an undercut form a holding region for locking and holding orFastening the holding element for fastening a line connector of a media line to which at least one second fluid connection device is provided. The at least two locking lugs provided with an undercut are sufficient to create a holding area as a replacement for the holding collar on the at least one first fluid connection device, via which holding area a fastening of a holding element for holding or fastening a line connector is possible. The undercut of the at least two locking lugs means that they protrude in a nose-like manner over the outside of the second fluid connection device, so that, as with a holding collar on the at least one first fluid connection device, engagement behind a holding element for fastening a line connector arranged at the end of a media line to the at least one second fluid connection device is possible.
[0009] After its production by the injection molding process, the fluid-conducting structural component is demolded by opening the injection molding tool in at least a first plane, namely the main extension plane of the fluid-conducting structural component, in which the first fluid connection devices extend. Advantageously, a structural element is arranged at least in the region of the at least one fluid path and at least a portion of the at least one second fluid connection device, and at least one through-opening is provided between the inside of the structural element and the outside of the fluid path. Of the at least two through-openings, one is arranged between the one outside of the fluid path, in particular the fluid channel, and the inside of the at least one structural element, and the at least one other is arranged on the opposite side of the fluid path, in particular the fluid channel, between its outside and the inside of the at least one structural element.The at least two locking lugs, which are formed on the outside of the at least one second fluid connection device, are demolded from the side of the undercuts of the locking lugs. To enable this, the fluid-conducting structural component has, at least in this region, at least two through-openings between the at least one second fluid connection device, the at least one fluid path, in particular the fluid channel, and the structural element spaced from the at least one second fluid connection device. The fluid-conducting structural component can be easily demolded in the region of the at least two locking lugs of the at least one second fluid connection device through the at least two through-openings.The demolding of all fluid connection devices of the injection-molded fluid-conducting structural component can thus take place approximately perpendicular to its main extension plane, the main extension plane of the fluid-conducting structural component, in the opening direction of the injection mold. When the injection mold is opened, the at least one upper injection mold part is removed from the at least one lower injection mold part. From the at least one lower injection mold part, the at least one second fluid connection device is demolded in the region of its at least two locking lugs, thus from the side of its undercut, i.e. from the direction of the lower injection mold part. Demolding can take place using appropriately shaped demolding elements, which in particular engage the locking lugs on the side of their undercut.
[0010] By providing the at least one structural element, which is arranged at a distance from the at least one second fluid connection device and by providing the at least two through-openings between the inside of the at least one structural element and the outside of the fluid path, in particular the fluid channel, a stable structure of the fluid-conducting structural component can be created around the at least one second fluid connection device. At the same time, problem-free demolding of the at least two locking lugs of the at least one second fluid connection device is possible through the at least two through-openings. The at least one structural element can surround the at least one second fluid connection device at least in part or even completely.For example, the at least one structural element can be at least partially annular and / or designed as a polygonal line, in particular as a closed polygonal line, e.g. as a closed regular or irregular polygonal line, for example polygonal in plan view, such as rectangular, square, hexagonal, and / or have a rounded shape. In particular, it is possible to design the structural element partially annular, flattened in one or more sections in order to enable problem-free fastening of a holding element, such as a holding clamp, to the holding collar of the at least one first fluid connection device, especially in the area that covers the at least one first fluid connection device, for connecting it to a media line or a line connector arranged at the end thereof.
[0011] The at least one second fluid connection device is further advantageously provided on the outside with at least one support rib, in particular at least two support ribs, for stabilizing the at least one second fluid connection device. The at least two support ribs advantageously extend spatially between the two locking lugs along the longitudinal extent of the second fluid connection device. In particular, the at least two support ribs can be arranged opposite one another on the outside of the second fluid connection device. Since the at least two opposing locking lugs extend on the outside of the second fluid connection device in the region of the through-opening(s) between the fluid path, in particular the fluid channel, and the structural element, the at least two support ribs can be arranged on the outside of the second fluid connection device aligned at an angle of approximately 90° to the at least two locking lugs.The at least two support ribs then extend over the fluid path, in particular the fluid channel, in the longitudinal direction of the second fluid connection device. This enables particularly good support and stabilization of the second fluid connection device. The at least two support ribs end in particular on the outside of the at least one fluid path, in particular the fluid channel, and are in particular integrally connected to the fluid path or its outer wall or are formed as a single piece.
[0012] Further advantageously, the at least one second fluid connection device has at least one anti-twist device for preventing rotation of a line connector of a media line to be connected or connected to it from turning. In particular, the at least one anti-twist device can be formed by the at least one support rib on the second fluid connection device or in addition to this, in particular on its outer side. The at least one support rib arranged or provided on the outside of the second fluid connection device thus advantageously comprises or forms the anti-twist device for preventing rotation of a holding element to be arranged or arranged on this device for holding a line connector of a media line that is to be or is connected to the second fluid connection device.The retaining element can engage or interact with the anti-twist device so that rotation of the retaining element about the longitudinal axis of the second fluid connection device can be prevented. Rotation of a media line connected to or to be connected to the second fluid connection device, or of its line connectors, about the longitudinal axis of the second fluid connection device can thereby be prevented. This can prove advantageous, particularly during installation in an arrangement such as a vehicle, in order to keep all media lines that are or will be connected to the corresponding fluid connection devices of the fluid-conducting structural component in an optimal position. This prevents damage to the media lines on the one hand, and maintains a space-optimized arrangement of these lines on the other.
[0013] Further advantageously, the fluid-conducting structural component comprises at least one grid-shaped structural region. This makes it possible to thermally decouple individual regions of the fluid-conducting structural component from other adjacent regions, since little or hardly any heat is / can be transferred via the respective grid-shaped structural region of the fluid-conducting structural component. In contrast, other regions of the fluid-conducting structural component can be thermally coupled in a targeted manner, in which case, for example, no grid-shaped design of the fluid-conducting structural component is provided in these regions. Known fluid-conducting structural components typically feature fully closed plastic geometries.This results in a relatively large projected surface area relative to the component volume, which, in the context of manufacturing such a fluid-conducting structural component, inevitably requires an injection-molding machine park that must be capable of producing such large components. Large surfaces lead to large clamping forces of the machine and thus to high investment costs and, accordingly, also to high component costs. In the fluid-conducting structural component according to the invention, in contrast, regions that do not fulfill fluidic functions can advantageously be formed in a grid-like manner. This also allows the dimensions of a corresponding injection-molding machine for producing a fluid-conducting structural component to be reduced compared to the prior art.Likewise, the material usage in the manufacture of an injection-molded fluid-conducting structural component, in particular for use in a thermal management module, can be reduced compared to the state of the art, and the distortion of the component can also be reduced compared to large-volume injection-molded geometries of the state of the art.
[0014] By providing at least one lattice-shaped structural region, it is also possible to work with lower pressures compared to the production of large-volume injection-molded geometries of the thermal management modules of the prior art. Furthermore, it is possible to ensure sufficient holding pressure effectiveness during the injection molding process to avoid defects or vacuoles, particularly in the lattice-shaped structural regions of the fluid-conducting structural component to be produced, so that after shrinkage during cooling of the injection molding compound, no defects remain, especially not in the lattice-shaped structural regions of the fluid-conducting structural component.Furthermore, a more homogeneous material distribution can be provided and less material is required for the production of the fluid-conducting structural components according to the invention than in the injection molding geometries of fluid-conducting structural components of the prior art, so that the costs for this can also be kept lower compared to the prior art.
[0015] Advantageously, the at least one fluid path, in particular fluid channel, is surrounded by at least one grid-shaped structural region. The grid-shaped structural region further advantageously comprises, in the region of the at least one second fluid connection device, the at least one structural element spaced apart from the at least one second fluid connection device. During the opening and closing movement of the injection mold, it is thereby possible for the at least one upper part of the injection mold and the at least one lower part of the injection mold to alternately penetrate through the respective other of the upper part of the injection mold and the lower part of the injection mold to produce the at least one grid-shaped structural region and the at least one structural element with the at least two through openings.Thus, the grid-shaped structural regions, as well as the first and second fluid connection devices, can be easily demolded during the opening movement of the injection mold. The grid-shaped structural regions, as well as the at least one structural element with the at least two through-openings, which at least partially or sectionally surrounds the at least one second fluid connection device, which is or is to be formed along the at least one fluid path, in particular the fluid channel, can be produced in the injection mold by sections of the at least one injection mold upper part and the at least one injection mold lower part that dip into one another during the closing movement of the injection mold.Additional auxiliary equipment, which must be moved, in particular, transversely to the extension of the upper and lower parts of the injection molding tool, is therefore required neither for the injection molding of the fluid-conducting structural component nor for its demolding. Instead, after opening the injection mold or the injection molding tool, a simple demolding of the injection-molded fluid-conducting structural component is possible in a direction perpendicular to the main extension plane of the fluid-conducting structural component.
[0016] The fluid-conducting structural component with its at least one first fluid connection device and its at least one second fluid connection device, which run along the at least one fluid path, in particular the fluid channel, which opens into the at least one first fluid connection device at the end, is very well suited for forming a supporting structural component of a thermal management module. At least one component for conveying the temperature control medium and at least one component for regulating the mass flow can be arranged on the supporting structural component or fluid-conducting structural component, or can be integrated into it. A component for conveying the temperature control medium can be a pump device, in particular, and a component for regulating the mass flow can be a valve, in particular. Both the at least one component for conveying the temperature control medium and the at least one component for regulating the mass flow can thus be arranged on and / or in the supporting or fluid-conducting structural component.fluid-conducting structural component in order to convey and regulate mass flows within the thermal management module in the desired manner and thus to distribute them to individual temperature control circuits of a vehicle in which the thermal management module is accommodated. The temperature control circuits comprise media lines that are connected to the thermal management module or its supporting fluid-conducting structural component in the region of its at least one first and at least one second fluid connection device. The temperature control circuits can be used to control the temperature of vehicle components, such as a battery, such as a traction battery, and electronic components, wherein heat exchangers and / or temperature control devices or heat sources and / or heat sinks are or can be arranged in the partial circuits.At least one or more sub-circuits can thus be connected to the respective fluid path, in particular the fluid channel, which is in fluid communication with the at least one first fluid connection device as well as with the at least one second fluid connection device. Managing mass flows means that fluid medium mass flows within the thermal management module are conveyed, in particular pumped, by the at least one component for conveying the temperature control medium, and can be metered, adjusted or regulated accordingly by the at least one component for mass flow control and supplied to the respective fluid connection devices of the thermal management module or from its supporting, fluid-carrying structural component. As a result, the mass flows of temperature control medium within the closed temperature control circuit or from its sub-circuits can be supplied to vehicle components to be temperature-controlled.Such thermal management modules and temperature control circuits can be used to control the temperature of vehicle components, in particular of an electric or hybrid-electric vehicle.

[0022] Figure 1 shows a plan view of an inventive
[0023] Thermal management module 1 for managing mass flows of a temperature control medium in a temperature control circuit of a vehicle is shown. The thermal management module comprises a fluid-conducting structural component 2, which is also the supporting structural component of the thermal management module 1. This means that on the supporting fluid-conducting structural component, on the one hand, components for conveying the temperature control medium in the form of a first
[0024] On the one hand, a pump device 3 and a second pump device 4 are arranged, and on the other hand, three valves 5, 6, 7 are arranged as components for mass flow control. Both the two pump devices 3, 4 and the valves 5, 6, 7 are each arranged in the intersection region of fluid paths or fluid channels 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 60 of the fluid-conducting structural component 2. At the end of the fluid channels 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 60, a first fluid connection device 23 or 24 or 25 or 26 or 27 or 28 or 29 or 30 or 31 or 32 or 33 or 34 is arranged. Furthermore, along the longitudinal extension or longitudinal axis L 13 of the fluid channel 13, a second fluid connection device 8 is arranged, which extends with its longitudinal extension or longitudinal axis L8 perpendicular to the longitudinal extension or longitudinal axis L 13of the fluid channel 13. Both the first fluid connection device 26 and the second fluid connection device 8 are fluidically connected to the inner flow lumen of the fluid channel 13, so that fluid or tempering medium flowing through the fluid channel 13 or its inner lumen can exit through the first fluid connection device 26 and through the second fluid connection device 8 or, conversely, flow through these selectively or together into the fluid channel 13.
[0025] The supporting fluid-conducting structural component 2 comprises, in addition to the number of fluid channels 10 to 22, 60 and first fluid connection devices 23 to 34, which all lie in the main extension plane or plane E1 of the fluid-conducting structural component 2 (corresponding to the drawing plane in Figure 1), as well as the second fluid connection device 8 arranged perpendicular to the fluid channel 13, a number of lattice-shaped structural regions 9. The lattice-shaped structural regions 9 are formed substantially between the fluid channels 10 to 22, 60 and thus form a large part of the body of the fluid-conducting structural component 2. The lattice-shaped structural regions 9 comprise intersecting webs 90, 91, in particular webs 90, 91 which are perpendicular to one another, as well as through-openings 92 formed between them. The body of the fluid-conducting structural component 2 is thus of skeletal design.On the outside of the fluid-conducting structural component 2 of the thermal management module 1, four fastening points 101, 102, 103, 104 are provided, to which the thermal management module 1 or its supporting fluid-conducting structural component 2 can be fastened in a vehicle, in particular to its body.
[0026] As can be further seen from Figures 2 to 4, the fluid connection devices 25, 26, 27, which are arranged at the ends of the fluid channels 12, 13, 14, each have a circumferential retaining collar 35 for holding and securing a holding element (not shown) and, via this, a line connector of a media line. Instead, the second fluid connection device 8 has two opposing locking lugs 80, 81, each provided with an undercut 82, 83. The undercuts 82, 83 are particularly clearly visible in Figures 3 and 4. The locking lugs 80, 81 provided with the undercuts 82, 83 serve to form a holding area for a holding element 100, indicated by dashed lines in Figure 2, for holding and securing a line connector of a media line to the second fluid connection device 8.Demolding a circumferential retaining collar, such as the circumferential retaining collar 35 on the first fluid connection devices 23 to 34, would not be possible in a simple manner. To enable easy demolding of the entire fluid-conducting structural component 2 in one plane, namely in the plane E1 of the first fluid connection devices 23 to 34 or the fluid channels 10 to 22, 60 or the grid-shaped structural regions 9, only the locking lugs 80, 81 with their undercuts 82, 83 are provided.
[0027] The grid-shaped structural region 9 further comprises an annular structural element 95 around the second fluid connection device 8. This is designed as a circumferential or closed structural element 95 and has a flattened portion 96 in the region where it overlaps the fluid connection device 26. This makes it possible to easily arrange a holding element 100 on the fluid connection device 26 or on its holding collar 35 in order to fasten a line connector of a media line there.
[0028] As can further be seen from Figure 2, a distance A is left all the way around the second fluid connection device 8 between the inner side 97 of the annular structural element 95, also in the region of its flattened portion 96, and the outer side 84 of the second fluid connection device 8. The distance A is selected to be large enough that a through-opening 98, 99 remains on either side between the inner side 97 of the annular structural element 95 and the outer side 130 of the fluid channel 13. Demolding of the second fluid connection device 8 in the region of its locking lugs 80, 81 from the direction of its undercuts 82, 83 is possible through these two through-openings 98, 99. This is indicated in Figure 4 by the arrows P1, P2.The fluid-conducting structural component 2, which is produced in particular by plastic injection molding, can thus be demolded in the opening direction of the injection molding tool for demolding by engaging demolding elements through the through-openings 98, 99 in the annular structural element 95 and engaging the projecting locking lugs 80, 81. Thus, demolding of the manufactured load-bearing fluid-conducting structural component 2 is possible in a single plane, namely perpendicular to the plane E1.
[0029] In order to provide anti-twist protection on the second fluid connection device 8, said device has two support ribs 85, 86 extending in the direction of its longitudinal axis L8 or parallel to it. As can be seen particularly clearly from Figures 2 and 3, the two support ribs 85, 86 extend between the two locking lugs 80, 81. The support ribs 85, 86 and the two locking lugs 80, 81 are each arranged crosswise in pairs with respect to one another, so that the two locking lugs 80, 81 lie opposite one another, partially overlapping the two through openings 98, 99 of the annular structural element 95, and the two support ribs 85, 86 also lie opposite one another, covering the fluid channel 13 and supporting the outer side 130 thereof or formed integrally with it.The two support ribs 85, 86 are each designed in such a way that they can be easily demoulded in the opening direction of an injection moulding tool upper part when it is opened, which is indicated by the arrow P3 in Figure 4.
[0030] On the respective outer sides 185, 186 of the two support ribs 85, 86, these are not uniformly flat, but rather have an external step, as can be clearly seen in Figures 2 and 3. Alternatively, the support ribs 85, 86 can also be uniformly flat, without such a step.
[0031] As can be clearly seen particularly clearly in Figures 3 and 4, the second fluid connection device 8 is inserted into the structure of the supporting fluid-conducting structural component 2, as shown, in its lattice-shaped structural regions 9, protected from the outside by the annular structural element 95. Forces and bending moments can be absorbed by the surrounding lattice structure of the lattice-shaped structural regions 9 of the supporting fluid-conducting structural component 2 of the thermal management module 1. This allows, in particular, all fluid channels 10 to 22, 60 within the supporting fluid-conducting structural component 2 to be protected against damage. The pump devices 3, 4 and valves 5, 6, 7 attached to the supporting fluid-conducting structural component 2 can also be accommodated in a protected manner in the fluid-conducting structural component 2.Furthermore, very good ambient air flow around the grid-shaped structural regions 9 of the supporting grid-shaped structural component 2 is possible, in particular to enable the absorption and / or dissipation of heat. The heat exchange or insulation of subfunctional regions of the thermal management module 1 can be varied by varying the grid structure of the grid-shaped structural regions 9, i.e., the ratio of webs 90, 91 to through-openings 92. In particular, all regions of the fluid-conducting structural component that are not functional regions can be designed as grid-shaped structural regions 9. This allows the size of the required injection molding machine or injection molding tool to be reduced.
[0032] When opening and closing the injection mold, all areas of the lattice structure of the lattice-shaped structural regions 9 can be created by alternating penetration of the upper and lower parts of the injection mold. Through the different design of the lattice-shaped structural regions 9 of the supporting fluid-conducting structural component 2, in particular the positioning and shape of the through-openings 92 and webs 90 and 91, not only can specific rigidity changes be made, but also specific mechanical stress relief of individual regions of the supporting fluid-conducting structural component of the thermal management module 1 can be created, but also more flexible regions of the supporting fluid-conducting structural component 2 can be created.The lattice structure of the lattice-shaped structural regions 9 can change the original shape of the through-openings 92 under the action of load, so that an actually square through-opening 92, for example, is deformed under the action of force into a diamond-shaped one. The lattice-shaped structural regions 9 can therefore be used to specifically create mechanically more flexible regions of the fluid-conducting structural component and thus of the thermal management module 1 in order to keep loads that are detrimental to function away from sensitive regions of the thermal management module, such as weld seams and other sealing and functional regions of the thermal management module 1. Furthermore, by providing the lattice-shaped structural regions 9, it is possible that when the thermal management module 1 is arranged in the engine compartment of a vehicle, no or very fewfewer siphon areas are created, which has a positive effect on possible dirt accumulation, since dirt and splash water can flow off unhindered through the grid structure of the grid-shaped structural areas 9.
[0033] In addition to the embodiments of fluid-conducting structural components described above and shown in the figures, numerous further embodiments can be provided, in particular any desired combinations of the above-mentioned features thereof, wherein the fluid-conducting structural components each have at least one first fluid connection device and at least one second fluid connection device as well as at least one fluid path, in particular fluid channel, wherein the at least one second fluid connection device extends along the fluid channel perpendicular to the latter and to the at least one first fluid connection device and wherein the at least one fluid channel opens into the at least one first fluid connection device, thus being or being able to be brought into fluid communication with both the at least one first fluid connection device and the at least one second fluid connection device.At least two locking lugs are provided on the outside of the at least one second fluid connection device, which serve to form a holding region for fastening a holding element to the second fluid connection device for fastening a media line or a line connector arranged at the end thereof. Demolding of the fluid-conducting structural component follows from the side of an undercut of the respective locking lug through at least two through-openings formed between the at least one second fluid connection device, the at least one fluid path, in particular a fluid channel, and a structural element that at least partially surrounds the at least one second fluid connection device at a distance from the latter.
