In addition, DE 195 39 570 B4 discloses a headlight for vehicles.

[0003] The object of the present invention is to provide a cooling device for cooling at least a part of an electronic computing device for a motor vehicle, as well as a motor vehicle with such a cooling device, so that at least the part of the electronic computing device, also referred to as a control unit, can be cooled in a particularly advantageous manner.

[0004] This problem is solved according to the invention by a cooling device with the features of claim 1 and by a motor vehicle with the features of claim 10. Advantageous embodiments of the invention are the subject of the dependent claims.

[0005] A first aspect of the invention relates to a cooling device for cooling at least a portion of an electronic computing device, also referred to as a control unit, for a motor vehicle, also referred to simply as a vehicle. This means that the motor vehicle, preferably designed as a motor vehicle, in particular as a passenger car, has the cooling device in its fully manufactured state. The cooling device comprises the electronic computing device. In other words, the electronic computing device is a component of the cooling device. For example, at least one component of the motor vehicle can be operated, that is, controlled and / or regulated, by means of the electronic computing device. For this purpose, the electronic computing device can, for example, provide at least one control signal, in particular an electrical one, wherein the component can receive the control signal.The component can be operated, i.e., regulated and / or controlled, by means of the control signal. The electronic computing device, and thus the cooling device, has a housing, which is also referred to as the device housing or first housing. Whenever the housing is mentioned before and below, it refers to the first housing unless otherwise specified. The housing has a receiving space. In particular, the receiving space is bounded, especially directly, by the housing. The receiving space is also referred to as the first receiving space. Whenever the receiving space is mentioned before and below, it refers to the first receiving space unless otherwise specified. Furthermore, the electronic computing device comprises at least one electronic component arranged in the receiving space.For example, the electronic computing device comprises at least one printed circuit board (PCB), wherein the electronic component is arranged on the PCB and, in particular, supported by the PCB. The PCB is arranged in the receiving space and thus in the housing. Furthermore, the cooling device comprises at least one cooler, which is formed separately from the housing and is arranged at least partially, in particular at least predominantly and thus at least more than halfway or completely, in the receiving space and thus in the housing, and which is connected to the housing at least indirectly, in particular directly. This means that the housing and the cooler are separate elements formed from one another and connected to each other. The cooler comprises at least one first cooling channel, which is arranged at least partially in the receiving space and thus in the housing, and through which a cooling medium, preferably liquid, can flow.Preferably, the cooling medium is an integral part of the cooling device. For example, the cooling medium is a liquid, in which case it is also referred to as a cooling fluid. In particular, the first cooling channel is bounded by an inner circumferential surface of the cooler, especially directly. At least the sub-area of ​​the electronic computing device can be cooled by means of the cooling medium, in particular by allowing heat to be transferred from the sub-area to the cooling medium flowing through the first cooling channel, especially via the cooler.

[0006] The cooling device also features a nozzle that is separate from both the housing and the cooler. This means that the housing, the cooler, and the nozzle are separate components. The cooler is also referred to as the cooling element. The nozzle has a second cooling channel through which the cooling medium flows, and which is fluidically connected to the first cooling channel. This allows the cooling medium to flow through both the first and second cooling channels. If, for example, the nozzle is designed as a supply nozzle, the first cooling channel can be supplied with the cooling medium via the second cooling channel and thus via the nozzle, so that, in the direction of flow of the cooling medium through the cooling channels, the second cooling channel is located upstream of the first cooling channel.If the nozzle is designed as a discharge or return nozzle, the cooling medium can be discharged from the first cooling channel via the second cooling channel and thus via the nozzle, so that, in the direction of flow of the cooling medium through the cooling channels, the first cooling channel is located upstream of the second cooling channel. Cooling the electronic computing device prevents overheating, thus ensuring high performance even at high ambient temperatures.

[0007] In order to cool at least the partial area of ​​the electronic computing device in a particularly advantageous manner, the invention provides that the nozzle has a first part arranged in the receiving space and thus in the housing as well as in a first longitudinal region of the first cooling channel, which forms a second longitudinal region of the second cooling channel, in particular limiting and, more specifically, directly limiting it. Furthermore, the nozzle has a second part which is arranged outside the receiving space, outside the housing, and outside the cooler. In particular, the second part is arranged in the vicinity of the housing. The second part forms a third longitudinal region of the second cooling channel, wherein, for example, the third longitudinal region of the second cooling channel is limited by the second part, in particular directly.This means that the second and third length sections of the second cooling channel are fluidically connected, allowing the cooling medium to flow through both sections. In principle, it would be conceivable for the parts of the nozzle to be formed separately and connected to each other. Furthermore, it is conceivable that the parts of the nozzle are formed integrally, i.e., from a single piece. In other words, it is conceivable that the parts of the nozzle are formed integrally, so that they are not formed as separately formed and connected parts, but rather are preferably formed from a single piece and thus constituted as a monoblock.The monoblock is a one-piece, and therefore integrally manufactured, integral body, which is not composed of separately formed and connected elements, but is formed in one piece, that is, from a single piece.

[0008] The first part of the nozzle has a first thread, in particular an external thread, which is screwed, in particular directly, into a second thread, in particular an internal thread, located in the first longitudinal section of the first cooling channel. For example, the first thread is screwed, in particular directly, into the second thread. The first thread of the nozzle is an integral thread of the nozzle and is therefore also referred to as the nozzle's internal thread.

[0009] A first section of the first part is sealed against the cooler in a first sealing plane. For this purpose, the first section of the first part has, for example, a first sealing surface, and the cooler has, for example, a second sealing surface, wherein the first sealing surface is sealed against the second sealing surface. For example, a first sealing element, formed separately from the cooler and separately from the nozzle, is provided, by means of which, for example, the first sealing surface is sealed against the second sealing surface, and thus the first section of the first part of the nozzle is sealed against the cooler in the first sealing plane. In particular, the first sealing element can be a solid, and the first sealing element can, for example, be made of an elastically deformable material, especially rubber.For example, the first sealing element is designed as a first sealing ring, in particular as a first O-ring. Furthermore, it would be conceivable that the first sealing element is a liquid sealant, in particular a first sealing paste.

[0010] According to the invention, a second region of the second part of the nozzle, spaced apart from the first region, is sealed against a component of the cooling device in a second sealing plane that is spaced apart from the first sealing plane and, for example, runs parallel to the first sealing plane. For this purpose, the first region has, for example, a third sealing surface and the component has a fourth sealing surface, wherein, for example, the third sealing surface is sealed against the fourth sealing surface. For example, a second sealing element, formed separately from the nozzle, the component, and the first sealing element, is provided, by means of which, for example, the third sealing surface is sealed against the fourth sealing surface, and thus the second region of the second part of the nozzle is sealed against the component. It is conceivable that the second sealing element is designed as a solid body.For example, the second sealing element is made of an elastically deformable material, in particular rubber. For example, the second sealing element can be a second sealing ring, in particular a second O-ring. Furthermore, it is conceivable that the second sealing element is designed as a second liquid seal, in particular as a second sealing paste. For example, the first sealing surface is formed by an outer circumferential surface of the first area, and for example, the second sealing surface is formed by an outer or inner circumferential surface of the cooler. For example, the third sealing surface is formed by an outer circumferential surface of the second area. For example, the fourth sealing surface is formed by an outer or inner circumferential surface of the component.For example, the first sealing element rests, in particular directly, against the first area, in particular against a first sealing surface. For example, the first sealing element rests, in particular directly, against the cooler, in particular against a second sealing surface. For example, the second sealing element rests, in particular directly, against the second area, in particular against a third sealing surface. For example, the second sealing element rests, in particular directly, against the component, in particular against a fourth sealing surface. The invention allows the fitting, for example designed as a cooler nozzle or also referred to as a cooler nozzle, to be sealed particularly advantageously and in a space-saving, weight-saving, and cost-effective manner in both sealing planes against the cooler and against the component.The sealing of the nozzle against the cooler occurs in the first longitudinal section of the first cooling channel, and thus within the cooler, the receiving chamber, and therefore within the housing. The sealing of the nozzle against the component occurs outside the receiving chamber, outside the first cooling channel, outside the cooler, and outside the housing. Furthermore, the invention allows the cooling medium to be advantageously and precisely routed, enabling effective and efficient cooling of at least a portion of the electronic computing device. Additionally, the cooling device can be assembled and manufactured particularly advantageously and, in particular, in a time- and cost-effective manner, especially because the cooler can be easily and thus quickly and cost-effectively connected to the housing. Moreover, the nozzle can be assembled quickly and cost-effectively, and in particular, sealed against the cooler and the component.Furthermore, the invention enables active cooling of the electronic computing device by means of a cooling medium. Active cooling means that the cooling medium, also referred to as a coolant, flows through the cooling channels, thereby removing heat from at least the affected area and thus cooling that area. For example, the cooling channels are arranged in a cooling circuit through which the cooling medium flows, and in which, for example, a pump may be located. The pump is, for example, an electrically operated pump. The pump can circulate the cooling medium through the cooling circuit and thus through the cooling channels. By means of the cooling medium, waste heat can be effectively and efficiently removed from the affected area and thus from the electronic computing device, and in particular, drawn out of the electronic computing device.

[0011] The nozzle, in particular the second part of the nozzle, can be connected, or connectable, for example, in a way that is particularly detachable without damage, to a conduit element formed separately from the nozzle and through which the cooling medium flows. In particular, the conduit element extends at least partially outside the receiving space and thus outside the housing and outside the cooler. Preferably, the conduit element is formed separately from the housing and separately from the cooler. For example, the nozzle, in particular the second part of the nozzle, is designed as a quick-release coupling, in particular a VDA quick-release coupling, so that the conduit element can be connected to the nozzle in a particularly simple, time-saving, and cost-effective manner, both mechanically and fluidically, in particular by simply pushing the conduit element onto the nozzle, in particular onto the second part.Typically, such fittings are designed for a direct seal to the cooler, particularly in the aforementioned first sealing plane. An additional sealing plane, such as the previously mentioned second sealing plane, can usually only be created with considerable complexity and, in particular, only with the use of additional components. If the fitting were not to have its own thread and were, for example, attached to the housing in such a way that at least one screw penetrated the fitting, especially the flange of the fitting, and was screwed into the housing, then particularly large screw holes would be required, due to tolerances between the cooler and the housing as well as tolerances between the fitting and the housing.Furthermore, it would be conceivable to attach the fitting to the housing by means of a clamp or clip designed separately from the housing and the fitting itself, such that the clamp or clip is attached to the housing by means of an additional, separate screw element, thereby pressing the fitting, particularly via its flange, against the housing. However, this would result in a large number of components and a high installation space requirement. In contrast, the invention now provides that the fitting has its own thread in the form of the first thread, so that the first thread of the fitting is also referred to as the fitting's own thread.

[0012] Preferably, the first thread is an external thread, and preferably the second thread corresponding to the first is an internal thread. In particular, the threads are screwed directly together, especially directly into one another. This allows the fitting to be sealed against both the housing and the cooler in a space-saving, weight-efficient, and cost-effective manner at both sealing levels. Compared to conventional solutions, the installation space required and the number of parts can be kept to a particularly low level.

[0013] In one embodiment of the invention, the component is a housing element of the housing that at least partially, and in particular directly, delimits the receiving space. In this embodiment, the second area of ​​the second part of the nozzle is sealed against the housing in whose receiving space the cooler is arranged. This allows for effective and efficient cooling of the electronic computing device in a particularly space-saving manner.

[0014] It has proven particularly advantageous if the cooler is connected to the housing element, especially directly. For example, the cooler is screwed to the housing element by means of at least one or more screw elements that are designed separately from the cooler and separately from the housing element, and thus connected.

[0015] It has proven particularly advantageous if the component is a housing element of a second housing of the cooling device, designed separately from the housing, provided in addition to the housing (first housing), and arranged outside the housing and outside the receiving space. This allows the housing elements to be arranged relative to each other in a particularly space-efficient and needs-based manner, enabling a particularly advantageous and space-saving routing of the cooling medium, so that at least the relevant section of the electronic computing device can be cooled effectively, efficiently, and in a space-saving manner.

[0016] In a further, particularly advantageous embodiment of the invention, the second housing is a storage housing of an electrical energy storage device in which, or by means of which, electrical energy, in particular electrochemical energy, is to be stored or stored. Most preferably, the electrical energy storage device is a high-voltage component whose electrical voltage, in particular its operating or nominal voltage, is preferably greater than 50 volts, particularly greater than 60 volts, and most preferably several hundred volts. Therefore, the electrical energy storage device is also referred to, for example, as a high-voltage storage device (HVS). For example, the motor vehicle in its fully manufactured state has at least one electric machine by means of which the motor vehicle can be driven, in particular purely, electrically.Preferably, the electric machine is a high-voltage component with an electrical voltage, in particular an operating or nominal voltage, preferably greater than 50 volts, particularly greater than 60 volts, and most preferably several hundred volts. For example, the electric machine can be supplied with electrical energy stored in the electrical energy storage device, enabling it to be operated as a motor. The electric motor can then be used to drive the vehicle, particularly in a purely electric manner. Since the electric machine is preferably used to drive the vehicle, it is also referred to as a traction machine.Since the electric machine can be powered by the electrical energy stored in the energy storage device and thus operated as an electric motor, the energy storage device is also referred to, for example, as a traction storage device or traction battery. The invention enables space-saving, lightweight, and cost-effective cooling of the section of the electronic computing unit, as an advantageous routing of the cooling medium can be implemented. Thus, the cooler can be advantageously supplied with the cooling medium via the nozzle, and / or the cooling medium can be particularly advantageously discharged from the cooler via the nozzle.

[0017] The second housing has a second receiving space located outside the first housing and outside the first receiving space, which is bounded by the second housing, in particular directly. Storage cells of the electrical energy storage device, designed to store electrical energy, are housed in the second receiving space. This means that the electrical energy is stored or stored by means of the storage cells, which are also simply referred to as cells. Preferably, the storage cells are electrically connected to each other.

[0018] It has proven particularly advantageous if the first housing is connected to the second housing, especially directly. This allows the installation space requirements, the number of parts, and the costs to be kept to a minimum. For example, the housings are abutting each other, especially directly.

[0019] Another embodiment is characterized by the fact that the electronic computing unit is designed as a battery management system (BMS) for the electrical energy storage device, so that, for example, the electrical energy storage device can be operated, in particular controlled or regulated, by means of the electronic computing unit. Thus, the aforementioned component is, for example, the electrical energy storage device. In this configuration, the electronic computing unit can be cooled particularly effectively and efficiently, as well as in a space-saving, weight-saving, and cost-effective manner.

[0020] In order to keep the installation space requirement particularly low and to achieve a particularly advantageous guidance of the cooling medium, it is further provided in the invention that the second housing has a through-opening which is penetrated by the nozzle.

[0021] Finally, it has proven particularly advantageous if the second part of the fitting has a tool engagement by means of which a torque can be positively transmitted between the fitting and a screwdriving tool for tightening the threads. Preferably, the tool engagement is designed as a non-circular or polygonal shape, in particular as an internal or external polygonal shape. The polygonal shape can, for example, be a square or a hexagon. This allows the fitting to be rotated particularly easily relative to the cooler, so that the first thread can be easily turned relative to the second thread. Thus, the fitting can be mounted quickly and cost-effectively, enabling particularly cost-efficient cooling of the electronic computing equipment.

[0022] A second aspect of the invention relates to a motor vehicle, also referred to simply as a vehicle, and designed, for example, as a motor car, in particular as a passenger car, which has at least one cooling device according to the first aspect of the invention. Advantages and advantageous embodiments of the first aspect of the invention are to be regarded as advantages and advantageous embodiments of the second aspect of the invention and vice versa.

[0023] Further details of the invention will become apparent from the following description of preferred embodiments with the accompanying drawings. These show: Fig. 1 a schematic and cutaway side view of a first embodiment of a cooling device for cooling at least a part of an electronic computing device for a motor vehicle; Fig. 2 a schematic front view of a first embodiment of a nozzle of the cooling device; Fig. 3 a schematic front view of a second embodiment of the nozzle; and Fig. 4 A schematic and partially cut-away side view of a second embodiment of the cooling device.

[0024] In the figures, identical or functionally equivalent elements are provided with the same reference numerals.

[0025] Fig. Figure 1 shows a schematic and cutaway side view of a first embodiment of a cooling device 1 for cooling at least a partial area T of an electronic computing device 2 for a motor vehicle, also referred to simply as a vehicle. This means that the motor vehicle, in its fully manufactured state, has the cooling device 1. The cooling device 1 comprises the electronic computing device 2, which is thus a component of the cooling device 1. By means of the electronic computing device 2, a Fig. 1. A component not shown, provided in addition to the electronic computing device 2, is operated, that is, in particular controlled or regulated. The electronic computing device 2 is also referred to as the control unit. The control unit has a housing 3, which is also referred to as the first housing or main housing. The housing 3 can, for example, have at least or exactly two separately designed and interconnected housing elements, namely a first housing element 4 and a second housing element 5. The housing 3 has a receiving space 6, which is also referred to as the first receiving space and is bounded, in particular directly bounded, by the housing 3, in particular by an inner circumferential surface 7 of the housing 3.

[0026] Out of Fig. Figure 1 shows that the receiving chamber 6 is partially bounded by the housing element 4 and partially by the housing element 5, in particular directly in each case. The section T to be cooled is located in the receiving chamber 6 and thus in the housing 3. The electronic computing device 2 has at least one Fig. Figure 1 shows a particularly schematic representation of an electronic component 8, arranged in the receiving space 6 and thus in the housing 3, which can, for example, be arranged in the sub-area T so that, for example, the electronic component 8 can be cooled. Fig. Figure 1 shows, particularly schematically, a component 9 of the electronic computing device 2, arranged in the sub-area T and thus requiring cooling. The component 9 can, for example, be or comprise the electronic component 8. The cooling device 1 has a cooler 10, which is formed separately from the housing 3 and arranged in the receiving space 6 and thus within the housing 3. The cooler 10 is connected to the housing element 5 and thus to the housing 3, particularly within the receiving space 6. For this purpose, screw elements 11, formed separately from the cooler 10 and the housing 3 and arranged at least partially within the receiving space 6, are provided. These screw elements connect the cooler 10 to the housing element 5 and thus to the housing 3. Each screw element 11 is, for example, a screw.The respective screw element 11 penetrates a corresponding, for example unthreaded, through-opening 12 of the cooler 10. The cooler 10 has at least one first cooling channel 13 arranged in and thus extending within the receiving chamber 6, through which a cooling medium, preferably liquid, can flow. The cooling medium is also referred to as coolant. Fig. Figure 1 illustrates the flow of the cooling medium through the first cooling channel 13, indicated by an arrow 14. Heat can be transferred from the sub-area T, particularly component 9, to the cooling medium flowing through the first cooling channel 13 via the cooler 10, thereby cooling the sub-area T, and especially component 9. It is evident that the cooling medium can cool the sub-area T by transporting the aforementioned heat away from the sub-area T.

[0027] The cooling device 1 also has a nozzle 15, which is separate from the housing 3 and the cooler 10 and is also referred to as a cooling nozzle or cooler nozzle. The nozzle 15 has a second cooling channel 16 through which the cooling medium flows and which is fluidically connected to the first cooling channel 13.

[0028] Out of Fig. Figure 1 shows that, for example, the first cooling channel 13 is bounded by an inner circumferential surface 17 of the cooler 10, in particular directly. Alternatively or additionally, the second cooling channel 16 is bounded by an inner circumferential surface 18 of the nozzle 15, in particular directly. In the case of the Fig. In the embodiment shown in Figure 1, the nozzle 15 is, for example, a return or discharge nozzle through which the cooling medium can be discharged from the cooler 10. This means that, in the direction of flow of the cooling medium through the cooling channels 13 and 16, the first cooling channel 13 is arranged upstream of the second cooling channel 16. However, this is only an example. Alternatively, the nozzle 15 could be a supply nozzle through which the cooler 10, i.e., the cooling channel 13, can be supplied with the cooling medium. In that case, in the direction of flow of the cooling medium through the cooling channels 13 and 16, the cooling channel 16 would be arranged upstream of the cooling channel 13.

[0029] In order to achieve particularly advantageous and efficient cooling of at least the sub-section T of the electronic computing device 2, the cooling device 1 is provided that the nozzle 15 has a first part T1 arranged in the receiving space 6 and in a first length section L1 of the cooling channel 13, which forms, and in particular limits, a second length section L2 of the second cooling channel 16. Furthermore, the nozzle 15 has a second part T2 arranged outside the receiving space 6, outside the housing 3 and outside the cooler 10, and in particular in a surrounding area 19 of the housing 3, which forms, and in particular limits, a third length section L3 of the second cooling channel 16.The third length range L3, for example, runs outside the recording space 6, outside the housing 3 and outside the cooler 10, and especially in the surrounding area 19.

[0030] The first part T1 of the nozzle 15 has a first thread 20, which in this case is an external thread. The first length section L1 of the first cooling channel 13 has a second thread 21 corresponding to the first thread 20, which in this case is an internal thread. The threads 20 and 21 are screwed directly together, that is, screwed directly into one another, in this case such that the thread 20 is screwed directly into the thread 21. Thus, the nozzle 15 is screwed directly to the cooler 10. Since the thread 20 is a thread of the nozzle 15, it is also referred to as the internal thread of the nozzle 15. Because the threads 20 and 21, and thus the nozzle 15 and the cooler 10, are screwed together directly, the nozzle 15 is connected to the cooler 10 within the receiving space 6, specifically directly.

[0031] Out of Fig. It is also apparent from Figure 1 that a first region B1 of the first part T1 of the nozzle 15 is sealed against the cooler 10 in a first sealing plane D1. For this purpose, the first region B1 has a first sealing surface, which is formed by an outer circumferential surface 22 of the region B1. The cooler 10 has a second sealing surface, which is formed by an inner circumferential surface of the cooler 10. The first sealing surface is sealed against the second sealing surface. For this purpose, a first sealing element 23 is provided, which is preferably designed as a solid. In the Fig. In the first embodiment shown in Figure 1, the first sealing element 23 is designed as a sealing ring, in particular as an O-ring. For example, the first sealing element 23 is made of an elastically deformable material, in particular rubber. The first region B1, in particular the first sealing surface, is supported against the cooler 10, in particular against the second sealing surface, by means of the first sealing element 23, for example, such that the first sealing element 23 bears against the first sealing surface on one side, in particular directly, and against the second sealing surface on the other, in particular directly, and thus directly against region B1 on one side and directly against the cooler 10 on the other.

[0032] A second region B2 of the second part T2 of the nozzle 15, which is spaced apart from the first region B1, particularly in the flow direction of the cooling medium flowing through the cooling channels 13 and 16, is sealed against a component of the cooling device 1 in a second sealing plane D2, which is spaced apart from the first sealing plane D1, particularly in the flow direction of the cooling medium flowing through the cooling channels 13 and 16. In the first embodiment, the component is the housing element 5 of the first housing 3, which at least partially, and in particular directly, delimits the receiving space 6. For example, the second region B2 of the nozzle 15 has a third sealing surface, which is spaced apart from the first sealing surface and from the second sealing surface, particularly in the flow direction of the cooling medium flowing through the cooling channels 13 and 16, and which is formed, for example, by the outer circumferential surface 22 of the nozzle 15.Furthermore, the housing element 5, for example, has a fourth sealing surface, which is spaced apart from the first, second, and third sealing surfaces and is formed, in particular, by an inner or outer circumferential surface of the housing element 5. The third sealing surface is sealed against the fourth sealing surface. For example, a second sealing element 24 is provided in addition to the first sealing element 23 and is formed separately from the first sealing element 23. Preferably, the second sealing element 24 is a solid. For example, the second sealing element 24 is made of an elastically deformable material, in particular rubber. In the case of... Fig. In the first embodiment shown in Figure 1, the second sealing element 24 is, for example, a second sealing ring, in particular a second O-ring. By means of the second sealing element 24, the second area B2, in particular the third sealing surface, is sealed against the housing element 5, in particular against the fourth sealing surface, for example, such that the second sealing element 24 bears against the area B2, in particular the third sealing surface, on the one hand, in particular directly, and against the housing element 5, in particular the fourth sealing surface, on the other hand, in particular directly. Fig. It is evident from Figure 1 that area B1 is sealed radially, that is, in the radial direction of the nozzle 15, against the cooler 10. This means, in particular, that the first sealing surface and the second sealing surface are opposite each other along a first sealing direction, the first sealing direction being oblique or, in this case, perpendicular to the flow direction of the cooling medium flowing through the cooling channel 16. Area B2 is sealed radially, that is, in the radial direction and / or axially, that is, in the axial direction, against the housing element 5.This means that, for example, the third sealing surface and the fourth sealing surface are opposite each other along a second sealing direction and / or along a third sealing direction, the second sealing direction being inclined or perpendicular to the flow direction of the cooling medium flowing through the cooling channel 16, thus creating a radial seal of area B2 against the housing element 5. The third sealing direction is axial, i.e., parallel to the flow direction of the cooling medium flowing through the cooling channel 16. This is achieved, for example, by having a first part of the third sealing surface and a second part of the fourth sealing surface opposite each other along the second sealing direction. Alternatively or additionally, for example, a third part of the third sealing surface and a fourth part of the fourth sealing surface are opposite each other along the third sealing direction.It is conceivable that the second sealing element 24, in particular directly, abuts the first part of the third sealing surface and the second part of the fourth sealing surface. Alternatively or additionally, for example, the second sealing element 24, in particular directly, abuts the third part of the third sealing surface and the fourth part of the fourth sealing surface. It can be seen that the sealing planes D1 and D2 are axially spaced apart, that is, in the flow direction of the cooling medium flowing through the cooling channel 16. Furthermore, for example, the respective sealing planes D1 and D2 run perpendicular to the flow direction of the cooling medium flowing through the cooling channel 16.

[0033] In the first embodiment, the first sealing element 23 is a radial seal by means of which the area B1 is radially sealed against the cooler 10.

[0034] Since threads 20 and 21 are directly screwed together, i.e., screwed directly into one another, a direct screw connection between the nozzle 15 and the cooler 10 is provided. This direct screw connection eliminates the need for additional, separate connecting elements. Furthermore, it avoids additional, separate connection points, thus keeping the installation space requirement, the number of parts, the weight, and the costs to a particularly low level.

[0035] Fig. Figure 2 shows a schematic front view of a first embodiment of the nozzle 15. In the Fig. 2 shown, first embodiment of the nozzle 15, wherein the in Fig. 2 shown, first embodiment of the nozzle 15 in the Fig. In the first embodiment of the cooling device 1 shown in Figure 1, the second part T2 and thus the nozzle 15 have a tool engagement 25, which can be used in the Fig. In the first embodiment of the fitting 15 shown in Figure 2, two opposing and diverging planar surfaces 26 and 27 are present, the planes of which run parallel to and spaced apart from each other. A torque can be positively transmitted between the fitting 15 and a separate screwdriving tool for tightening the threads 20 and 21 by means of the tool engagement 25. Fig. In the first embodiment of the nozzle 15 shown in Figure 2, the tool engagement 25 is designed as a so-called outer-circumference wrench opening. Alternatively, an inner-circumference wrench opening would be conceivable.

[0036] Fig. Figure 3 shows a schematic front view of a second embodiment of the nozzle 15. This second embodiment of the nozzle 15 can be used with the first embodiment of the cooling device 1. In the second embodiment, the tool engagement 25 of the second part T2 is designed as an internal polygon, in this case as an internal hexagon.

[0037] Fig. Figure 3 shows a schematic and partially cutaway side view of a second embodiment of the cooling device 1. In the second embodiment, the component against which the second area B2 of the second part T2 of the nozzle 15 is sealed in the second sealing plane D2 is a housing element 28 of a second housing 29 of an electrical energy storage device 30 of the cooling device 1 and thus of the motor vehicle, which is formed separately from the housing 3, provided in addition to the housing 3 and arranged outside the housing 3 and outside the receiving space 6.The second housing 29 is also referred to as the storage housing and has a second receiving chamber 31 arranged outside the first housing 3 and outside the first receiving chamber 6, which is bounded, in particular directly, by the housing 29, in particular by an inner circumferential surface 32 of the housing 29. In the second receiving chamber 31 are . Fig. Four storage cells 33 of the energy storage device 30, shown in a particularly schematic way, are arranged, wherein electrical energy, in particular electrochemically, is to be stored or stored in the storage cells 33. The motor vehicle, also simply referred to as a vehicle, has an interior space 34, also referred to as a passenger compartment or passenger space, in which persons, such as the driver of the motor vehicle, can be located, particularly during a journey. The overall environment of the motor vehicle is in Fig. 4 with 35, where the environment 35 of the motor vehicle is an environment of the electrical energy storage device 30. The electronic computing device 2 is located in the Fig. In the second embodiment shown in Figure 4, a battery management system (BMS) for the energy storage device 30 is provided, which is operated, in particular regulated or controlled, by means of the battery management system. The interior 34 of the motor vehicle is divided by a Fig. 4. The structure 36 of the motor vehicle is shown in partial detail, wherein the structure 36 is preferably designed as a self-supporting body. From Fig. Figure 4 shows that the storage housing (second housing 29) is attached to the structure 36, at least indirectly, and in particular directly. In this case, the storage housing, and thus the energy storage device 30, is screwed to the structure 36 and thereby attached to it. Screw elements are provided for this purpose, by means of which the storage housing, and thus the energy storage device 30, is screwed to the structure 36 and thus attached to it. Of these screw elements, by means of which the storage housing, and thus the energy storage device 30, is screwed to the structure 36, the following is shown in Figure 4: Fig. 4. A screw element designated 37 and shown in a particularly schematic way is recognizable. Particularly schematically in Fig. Figure 4 also shows an electrical connection 38, by means of which the electronic computing device 2 is electrically connected to the energy storage device 30. For example, the connection 38 is designed as a high-voltage connection.

[0038] Out of Fig. Figure 4 also shows that the second housing 29 (storage housing) has a through-opening 39, which is penetrated by the nozzle 15. The housing 3 is arranged on a first side S1 of the second housing 29, with the first side S1 pointing upwards in the vehicle's vertical direction when the energy storage device 30 is installed. The energy storage device 30 assumes its installation position in the fully assembled state of the vehicle containing the energy storage device 30, with the installation position in Fig. 4 is shown. The vehicle's upward direction is in Fig.Figure 4 is illustrated by a double arrow 40. An arrow 41 illustrates the forward direction of travel of the vehicle, which runs along its longitudinal axis and can be driven forward along this direction. It is evident that the housing 3, the cooler 10, and the receiving chamber 6 are located, in particular, entirely, on side S1. Thus, the first part T1 of the nozzle 15 is located at least partially on the first side S1, with the nozzle 15 extending, for example, from the first side S1 through the through-opening 39 and extending to a second side S2 of the storage housing (second housing 29). The second side S2 faces away from the first side S1, and in this case, the second side S2 points downwards in the vehicle's vertical direction when the energy storage device 30 is installed.The second part T2 of the nozzle 15 is at least partially arranged on the second side S2, with the second area B2 on the second side S2 being sealed against the component (second housing 29). The sealing planes D1 and D2 are spaced apart from each other in the vertical direction of the vehicle (double arrow 40). In both the first and second embodiments, the installation space required for the nozzle 15 can be kept particularly small. Additional, separate connecting elements for attaching the nozzle 15 can be avoided, thus also eliminating the need for additional connection points for such elements. This allows the installation space requirement, the number of parts, and therefore the weight and costs to be kept to a particularly low level.
