Description

Technical Field

[0001] The invention relates to a device for conducting a cooling fluid in a motor vehicle and to a motor vehicle having such a device. Background Art

[0002] Certain devices in a motor vehicle need to be actively cooled by means of a cooling fluid. However, the movement of the device to be cooled can cause problems, whereby the fluid channels may be damaged and the cooling fluid may leak, which can lead to further damage. Summary of the invention

[0003] It is therefore the object of the present invention to specify an improved device for conducting a cooling fluid in a motor vehicle and a motor vehicle having such a device.

[0004] This object is achieved by the subject matter of the independent claim. Advantageous developments are given in the dependent claims.

[0005] According to a first aspect, a device for conducting a cooling fluid in a motor vehicle is specified.

[0006] Here, the device includes a first fluid channel, a second fluid channel and a sealing element, wherein the first fluid channel is fluidically connected to a fluid container and is designed to guide a cooling fluid flow from the fluid container in the first fluid channel, the second fluid channel is fluidically connected to a cooler and is designed to guide a cooling fluid flow in the second fluid channel and provide the cooling fluid flow to the cooler, which outputs / takes away heat from a device to be cooled in the motor vehicle, wherein the second fluid channel is received in the first fluid channel and fluidically connected to the first fluid channel, and the sealing element is arranged and designed at the first fluid channel in such a way that the second fluid channel is sealed in the first fluid channel, wherein the second fluid channel can be arranged in the first fluid channel in a manner that allows it to move within a predefined tolerance area so as to compensate for the movement of the cooler relative to the first fluid channel.

[0007] The device according to the invention is used in particular to allow movements of individual components of the cooling system relative to one another due to external factors within a tolerance range and thus to prevent or prevent malfunctions of the cooling system.

[0008] Here, the device comprises a first fluid channel and a second fluid channel, which are arranged to be movable relative to each other. The fluid channel (which can also be referred to as a channel, in particular a cooling channel or a pipeline, in particular a cooling pipeline) guides a cooling fluid in a cavity formed in the fluid channel. Here, the fluid channel can have any cross section, for example a circular, in particular a perfect circle or an ellipse, or a polygonal, in particular a rectangular or square, with or without rounded corners. The fluid channel can be designed in particular as a flat channel and has a significantly larger dimension in width than in height, for example the width is at least twice, three times, four times or five times the height.

[0009] In particular, the first fluid channel or the second fluid channel or the device is a closed cooling system or a closed cooling circuit, wherein the cooling fluid can be circulated or conveyed by means of a circulation element, such as a pump. To this end, the cooling fluid is conveyed from the fluid container via the first fluid channel and the second fluid channel to the cooler, where it is heated and conveyed back to the fluid container again via another path, such as via one or more return channels.

[0010] The cooling fluid guided in the first fluid channel and the second fluid channel is designed to absorb and remove heat from a heat source arranged at the cooler, especially on the outside of the cooler. The cooling fluid can also be called cooling liquid, coolant or generally referred to as fluid, which includes, for example, water, ethylene glycol or a mixture thereof.

[0011] The cooling fluid is designed to absorb heat generated by the heat source and output or radiated to the cooler via the fluid channel and thus remove heat from the heat source. The heat source is a device of the motor vehicle that must be cooled permanently or as required, for example a battery device consisting of one or more cells arranged adjacent to each other, which can also be referred to as a battery stack, or one or more computing units of the motor vehicle that perform calculations. In this case, indirect cooling is provided by the device, in particular in normal or normal operation, in which the cooling fluid does not come into direct contact with the heat source.

[0012] Here, the second fluid channel can be fixedly, especially rigidly connected to the cooler, which can also be fixedly, especially rigidly connected to the device to be cooled of the motor vehicle. For this purpose, the cooler can be welded, brazed or adhesively bonded to the second fluid channel, or formed integrally with the second fluid channel.

[0013] For this purpose, it is provided according to the invention that the second fluid channel is received in the first fluid channel and is fluidically connected to the first fluid channel.

[0014] Here, the first fluid channel and the second fluid channel can have substantially the same cross-sectional shape, but have different radii and / or diameters. In particular, the second fluid channel has a smaller cross-sectional area or radius than the first fluid channel. To this end, the second fluid channel can, for example, have a connection end in which the cross-sectional area or radius, in particular only the outer cross-sectional area or outer radius, gradually decreases compared to another part. Alternatively, the second fluid channel can also have a smaller cross-sectional area or radius, in particular a smaller outer cross-sectional area or outer radius, mostly or completely. The second fluid channel can be inserted or pushed into the first fluid channel in particular along the insertion direction.

[0015] For this purpose, the device has a sealing element which is arranged on the first fluid channel in such a way that it seals the second fluid channel in the first fluid channel.

[0016] The sealing element, which can also be referred to as a sealing element, can include one or more seals, as will be described later. For example, one or more O-rings and / or serrated seals can be provided, which are particularly arranged at or in the inner surface of the first fluid channel and seal the second fluid channel in the first fluid channel in a normal state, particularly in a predefined tolerance region, to prevent fluid leakage. For this purpose, the sealing element can act as a static friction for the second fluid channel, particularly based on its material properties.

[0017] In this case, the second fluid channel is arranged in the first fluid channel in such a way that it is movable within a tolerance region in order to compensate for a movement of the cooler and / or the second fluid channel relative to the first fluid channel.

[0018] In particular, the second fluid channel is movably arranged in the first fluid channel so that the second fluid channel can be displaced, in particular longitudinally displaced, in the hollow interior of the first fluid channel. In other words, the second fluid channel can be moved, in particular within predefined limits, for example within a tolerance zone, in particular only axially into the first fluid channel and out of the first fluid channel.

[0019] Here, the tolerance zone is, for example, several centimeters long, for example 5 centimeters, 10 centimeters, 15 centimeters, 20 centimeters or longer. In particular, the length of the tolerance zone is an integer multiple of the length of the diameter and / or cross section of the first fluid channel and / or the second fluid channel, for example two, three, four, five or ten times longer or longer.

[0020] The tolerance range represents a normal situation or a normal operating mode in which the second fluid channel can move without a blocking effect and / or cooling fluid loss. In particular, trouble-free operation of the device of the motor vehicle, in particular cooling, is ensured within the tolerance range.

[0021] In this case, apart from the sealing element, in particular no further or additional fixing elements or fixing means are provided. In particular, the first fluid channel is not joined to the second fluid channel. In particular, no latching connection, threaded connection or plug connection is provided, which fixes the second fluid channel to the first fluid channel and in particular locks the second fluid channel in the longitudinal direction, in which the second fluid channel is arranged movably relative to the first fluid channel.

[0022] Likewise, in particular, no additional grooves, springs or other clamping devices are provided to hold and / or preload the second fluid channel on the first fluid channel. In other words, the second fluid channel is arranged to be always displaceable or movable in and / or relative to the first fluid channel even in the normal movement mode or normal state and to seal the fluid outlet in the tolerance region in this normal state.

[0023] Due to driving movements and in particular driving maneuvers, mechanical components and therefore also fluid channels and coolers and devices of the motor vehicle to be cooled are subjected to external forces and accelerations in the motor vehicle, which can lead to or cause movements of the components. Alternatively or additionally, such movements can also be caused by chemically based expansion and contraction of one or more battery devices or cells, for example due to charging and discharging or temperature fluctuations, even when the motor vehicle is stationary.

[0024] The solution according to the invention makes it possible to block, compensate and / or compensate for such movements and to hold the fluid channels relative to one another in a sealed manner. The device according to the invention also prevents the second fluid channel from being disconnected or torn apart, in particular from being torn off, from the cooler and / or from the first fluid channel, so that the cooling fluid could leak out undesirably and in particular initially unnoticed and thus impair the cooling effect.

[0025] According to an improved solution, the sealing element has a first seal and a second seal, wherein the first seal defines the end point of the tolerance area and the starting point of the outer tolerance area, the second seal defines the end point of the outer tolerance area, and the second fluid channel is arranged in the first fluid channel in a manner that it can move out of the predefined tolerance area into the outer tolerance area.

[0026] In this refinement, two sealing elements, for example two O-rings, are provided, which are arranged one behind the other along the length of the first fluid element. The first sealing element is arranged in the first fluid channel, in particular further inwardly than the second sealing element, in particular in the direction of insertion or pushing of the second fluid channel into the first fluid channel.

[0027] The first sealing element thus marks or defines the start of a tolerance region extending further inwards from the first sealing element in the direction of insertion of the second fluid channel into the first fluid channel.

[0028] In the opposite direction, the first seal marks or defines the end point of the tolerance region and at the same time marks or defines the start point of the outer tolerance region in the direction opposite to the insertion direction, i.e. in the direction of pulling the second fluid channel out of the first fluid channel. The end point of the outer tolerance region is located at the second seal, which is located in particular in or at or near one end of the first fluid channel.

[0029] In other words, during the insertion or insertion of the second fluid channel into the first fluid channel, the second seal, with which the outer tolerance region begins, is first passed, in particular during or immediately after the insertion.

[0030] The insertion direction then continues past the first seal, which defines the end of the outer tolerance region and at the same time the start of the tolerance region. From here, the first fluid channel can be inserted further into the second fluid channel, in particular until a mechanical stop element is reached and prevents further insertion. The tolerance region extends up to this point.

[0031] The outer tolerance region is in particular shorter than the tolerance region, in particular is half, one third, one quarter as long or shorter than the tolerance region.

[0032] By arranging two seals, realize the particularly close fit of the first fluid channel in the second fluid channel.In addition, the two seals provide redundancy and spare positions.

[0033] The second fluid channel is arranged here to be movable not only within the tolerance region but also out of the tolerance region into the outer tolerance region. In particular, the second fluid channel is arranged relative to the first fluid channel in such a way that the second fluid channel can be positioned only in the outer tolerance region, in other words, an especially open end of the second fluid channel can be located in the outer tolerance region and therefore downstream of the first seal, counter to the insertion direction.

[0034] Such a position or such an arrangement of the second fluid channel relative to the first fluid channel is no longer considered normal operation as specified, but rather abnormal operation. This occurs in particular when the second fluid channel moves abnormally out of the first fluid channel due to abnormally high loads or movements, so that only the second seal ensures a tight fit and prevents fluid from escaping into the environment.

[0035] This development results in a particularly fail-safe device and cooling.

[0036] According to a development, the device further comprises an outlet which is arranged between the first seal and the second seal and is designed to output the cooling fluid flow into the environment.

[0037] The outlet can also be referred to as a hole or opening and is connected to the environment of the fluid channel, and in particular the environment of the motor vehicle. Another fluid channel can be connected to the outlet, which conveys the cooling fluid to a designated location, such as a collection container or a road surface.

[0038] The outlet is arranged between the first seal and the second seal and in particular also within the outer tolerance area and enables the cooling fluid to be discharged, in particular when the second fluid channel is displaced relative to the first fluid channel or moves out of the first fluid channel, for example due to movement of the second fluid channel and / or the cooler, so that the second fluid channel is only located within the outer tolerance area.

[0039] This refinement makes it possible to guide the cooling fluid to the intended location safely, in particular in a controlled manner, even in such unplanned or abnormal operating situations. In particular, this refinement prevents an unimpeded outflow, in particular to the outside of the cooler or to the device to be cooled, which could lead to faults, such as short circuits.

[0040] According to a development, the first seal has a different, in particular lower, degree of sealing than the second seal.

[0041] In particular, the second seal has a higher degree of sealing than the first seal. In the present case, the degree of sealing means the ability to prevent leakage of the cooling fluid. In particular, the degree of sealing includes sealing performance.

[0042] In other words, the second seal seals better, is stronger and / or is longer than the first seal. This can be achieved in particular by different materials, in particular material properties, diameters or sizes and / or masses of the two seals.

[0043] This refinement provides a two-stage seal. In particular, in conjunction with the optional outlet, small leaks caused by a reduced sealing function of the first seal can be discharged in a controlled manner and the seal relative to the device to be cooled of the motor vehicle is still permanently ensured.

[0044] According to a development, the device further comprises a humidity sensor which is arranged between the first seal and the second seal and which is designed to detect the presence of cooling fluid, the device being designed to perform remedial measures in response to this detection.

[0045] Humidity sensors are designed to recognize the presence of moisture near or at the sensor and convert this finding into a voltage or signal, for example by capacitance measurement, measuring conductivity and / or specific resistance.

[0046] The humidity sensor is arranged in particular in the outer tolerance region and can be placed, for example, at or in the outlet and can thus also detect the discharge of cooling fluid into the environment.

[0047] If moisture is detected in the second fluid channel in the outer tolerance range, an alarm can be triggered and remedial measures can be taken. For example, operating operations of the motor vehicle that cause movement and / or heat generation can be reduced or shut down, such as interrupting the charging process or reducing the charging power, increasing or reducing the pump power of the cooling fluid, reducing the motor power and / or computing power and / or reducing the speed. In addition, a notification about the remedial measures and / or the finding can also be provided together with the remedial measures.

[0048] With this improved solution, an impending or existing fluid leak can be quickly and safely identified and appropriate remedial measures can be taken to prevent or at least reduce damage to vehicle components and / or threats to physical integrity / personnel safety.

[0049] According to a further development, the device further comprises an emergency element which is designed to detect an emergency situation of the motor vehicle and to execute emergency measures in response to this detection.

[0050] An emergency situation may include an operation or manipulation of the motor vehicle that no longer ensures proper functionality or that threatens to lose proper functionality. For example, an emergency situation may be a temperature rise exceeding a predetermined threshold value of a device to be cooled, such as, in particular, a battery device or other components of the motor vehicle. In particular, an emergency situation may also be a fire or a burn.

[0051] As another example, the emergency situation may be an accident, a collision, for example a collision of a motor vehicle with or without external influences, wherein, for example, the battery device may also be deformed and / or damaged, which may lead to a fire.

[0052] These various critical situations can be detected and evaluated by suitable sensors, such as temperature sensors, deformation sensors and / or acceleration sensors.

[0053] In response to a determination of such an emergency situation, emergency measures are then taken to reduce or eliminate damage, particularly damage to life.

[0054] For example, the emergency measure can be one or more of the actions described above in conjunction with the remedial measures. Similarly, the emergency measure can also be, for example, operating a fire extinguishing device.

[0055] By means of this improvement, an impending or already occurring emergency situation can be identified quickly and safely, and appropriate remedial measures can be taken to prevent or at least reduce damage to motor vehicle components and / or threats to physical integrity / personnel safety.

[0056] According to a further development, the emergency measure comprises moving the second fluid channel out of the outer tolerance region so that the cooling fluid from the first fluid channel is supplied to the device to be cooled.

[0057] To this end, if an emergency situation is detected, the second fluid channel is moved out of the first fluid channel, first to the end of the tolerance region and then through the outer tolerance region until the opening of the second fluid channel also passes the second seal and cooling fluid can flow out of the first fluid channel.

[0058] This movement can be carried out, for example, by an actuator, which can also be referred to as an actuator, such as a servomotor. Alternatively or additionally, this movement can also be carried out by igniting an explosive, similar to the principle of an airbag.

[0059] The second fluid channel is moved out of the first fluid channel in such a way that the cooling fluid is supplied directly to the device to be cooled, in particular without passing through the second fluid channel.

[0060] In particular, this may lead to malfunctions, such as short circuits. However, this serves to prevent or contain a fire and is therefore considered to be more important than any damage to the vehicle's cooling system.

[0061] This development makes it possible to react quickly and effectively to emergency situations, in particular fires in motor vehicles, thereby avoiding greater damage, in particular loss of life.

[0062] According to the improvement plan, emergency measures include closing exits.

[0063] In this case, the emergency measures can be carried out as an alternative to or in addition to the previously described measures of moving the second fluid channel.

[0064] For this purpose, the first fluid channel and / or the outlet has a shut-off device which can be activated, in particular electronically.

[0065] The maximum fluid quantity can therefore be supplied either indirectly to the cooler when the second fluid channel has not yet moved beyond the second seal, or directly to the device to be cooled when the second fluid channel has moved out of the outer tolerance region.

[0066] A particularly effective emergency measure is thus provided.

[0067] According to another aspect, a motor vehicle is provided, which comprises a device according to one of the above-described embodiments. For example, the device is used to cool a battery device used as an energy storage device of the motor vehicle, or one or more computing units. The motor vehicle can be designed in particular as a purely battery-driven and / or hybrid-driven motor vehicle.

[0068] The motor vehicle according to the invention is preferably designed as a car, in particular a passenger car or a commercial vehicle, or as a bus or a motorcycle.

[0069] With regard to the embodiments of the motor vehicle and the advantages associated therewith, reference is made to the previously described embodiments of the device and the advantages associated therewith.

[0070] The invention also includes combinations of features of the described embodiments. Therefore, the invention also includes implementations each having a combination of features of a plurality of non-mutually exclusive described embodiments among the described embodiments.

[0080] The embodiments set forth below are preferred embodiments of the present invention. In the embodiments, the described parts of the embodiments each represent the features of the present invention that can be viewed independently of each other, and these features also improve the present invention independently of each other. Therefore, the present disclosure should also include those combinations of the features of the embodiments in addition to the combinations shown. In addition, the described embodiments can also be supplemented by other features of the present invention that have been described.

[0081] In the figures, the same reference numerals respectively denote elements with the same function.

[0082] Figure 1 A schematic cross-sectional view shows an embodiment of a device 100 for conducting a cooling fluid in a motor vehicle in a first position.

[0083] In this case, the device 100 belongs to a motor vehicle (not shown) and serves in particular to conduct a cooling fluid to a device 30 of the motor vehicle to be cooled.

[0084] The device 100 comprises a first fluid channel 110 which is fluidically connected to the fluid container 10 and is designed to conduct a cooling fluid flow from the fluid container 10 in the first fluid channel. The fluid container 10 can also be referred to as a supply and / or return channel, in particular a supply and / or return channel of a closed cooling circuit and comprises here, for example, a plurality of branches 11, but it is also possible to provide only a single branch, which extends to a plurality of devices according to the invention, only one device 100 being shown in detail here.

[0085] The device further comprises a second fluid channel 120, which is fluidically connected to the cooler 20, in which the first fluid channel is designed to guide a cooling fluid flow and to supply it to the cooler 20, which removes heat from a device to be cooled 30 of the motor vehicle. To this end, the second fluid channel 120 is rigidly or firmly connected to the cooler 20, which is rigidly or firmly connected to the device to be cooled 30, and the second fluid channel 120, the cooler 20 and the device to be cooled 30 can move as a whole relative to the first fluid channel and the fluid container 10.

[0086] The device 30 to be cooled is shown here by way of example as a battery device and is arranged in a housing 31 which defines a dry area 32 into which the cooling fluid should not enter in order not to damage the battery device. This is indirect cooling.

[0087] In this case, the second fluid channel 120 is received in the first fluid channel 110 and is fluidically connected to the first fluid channel.

[0088] The device 100 further comprises a sealing element 130 which is arranged and designed on the first fluid channel 110 in such a way that the second fluid channel 120 is held in the first fluid channel 110 and is sealed.

[0089] The second fluid channel 120 is arranged in the first fluid channel 110 so as to be movable within a predefined tolerance region 140 from left to right in the figure in order to compensate for a movement of the cooler 20 relative to the first fluid channel 110 .

[0090] The sealing element 100 comprises a first seal 131 and a second seal 132 , wherein the first seal 131 shown on the left side of the figure defines the end point of the tolerance region 140 and the start point of the outer tolerance region 150 , and the second seal 132 shown on the right side of the figure defines the end point of the outer tolerance region 150 .

[0091] The first seal 131 can have a different, in particular lower, degree of sealing than the second seal 132 .

[0092] If combined with the following Figure 2 and Figure 3 As shown and explained, the second fluid channel 120 is arranged in the first fluid channel 110 in such a way that it can move not only within a predefined tolerance region 140 but also out of the tolerance region into an outer tolerance region 150. The second fluid channel 120 is located in the first fluid channel 110 in such a way that one end 121 of the second fluid channel 120 is located in the tolerance region 140, in particular centrally in the tolerance region 140.

[0093] like Figure 1 As shown in the example, the length of the tolerance region 140 is the length of the cross section of the first fluid channel and the second fluid channel along the height rather than along the width (as shown below Figure 5a , Figure 5b , Figure 6a and Figure 6b ), and is also several times the length of the outer tolerance region 150 .

[0094] Figure 2 The second position is shown. Figure 1 Schematic cross-sectional view of a device 100.

[0095] It can be seen in particular that, for example, due to heating and / or expansion of the battery device, the device 30 to be cooled has moved to the right in the figure together with the second fluid channel 120 and the cooler 20, whereby the fluid channel 120 has moved into the tolerance region 140, in particular to the end of the tolerance region 140, so that the end 121 of the second fluid channel 120 is located near or at the first seal or aligned with the first seal at this end of the tolerance region 140. By means of the two seals 131, 132 provided, a tight fit, in particular a sealed fluid guide in the first and second fluid channels, can also be achieved.

[0096] Figure 3 In the third position, Figure 1 Schematic cross-sectional view of a device 100.

[0097] and Figure 2 Compared to the second position shown, the device 30 to be cooled together with the second fluid channel 120 and the cooler 20 moves further to the right side of the figure, whereby the fluid channel 120 has passed the end of the tolerance area 140 and is now only received and retained in the first fluid channel in the outer tolerance area 150, so that the end 121 of the second fluid channel 120 is only located in the outer tolerance area 50.

[0098] The second seal 132 of the sealing element 130 still seals the second fluid channel 120 in the first fluid channel 110 .

[0099] In this Figure 3 It can also be seen in FIG. 1 that an outlet 160 is provided, which is arranged in the outer tolerance region between the first seal 131 and the second seal 132 and is designed to discharge a cooling fluid flow to the environment.

[0100] In particular, a humidity sensor (not shown) can be arranged in the outlet 160 , which is designed to detect the presence of cooling fluid, whereby remedial measures can be triggered and carried out.

[0101] Also not shown is an emergency element, which is designed to detect an emergency situation of the motor vehicle and to execute emergency measures in response to this detection, wherein the emergency measures involve moving the second fluid channel 120 further to the right in the figure out of the outer tolerance area 150 out of the first fluid channel 110, so that the cooling fluid is directly supplied from the first fluid channel to the device 30 to be cooled and into the housing 31 or the actual dry area 32, in order to directly cool the battery device 30 and / or extinguish the fire. This movement can be achieved by an actuating element, not shown.

[0102] Additionally or alternatively, the emergency measures may also include closing the outlet, for example by a closing element, not shown. The closing element may also be closed by an actuating element, not shown.

[0103] Figure 4 Shows Figure 1 Schematic cross-sectional view of the device 100 along the cutting line.

[0104] In particular, the section lines AA and BB are shown here. Figure 5a , Figure 5b , Figure 6a and Figure 6b The device 100 and in particular the interaction of the first fluid channel 110 and the second fluid channel 120 are explained in two different positions.

[0105] Figure 5a Shows that in Figure 1 When the first position Figure 4 Schematic cross-sectional view of the device along the cutting line AA.

[0106] It can be seen here that the width of the second fluid channel 120 is significantly greater than its height and is designed here, for example, as a multiport fluid channel.

[0107] It can also be seen that a total of two outlets 160 are provided, one on each side. This is particularly ideal when the device 30 to be cooled moves or deforms asymmetrically. However, only a single outlet 160 can also be provided.

[0108] In this Figure 5a In the embodiment, the second fluid channel 120 is arranged according to Figure 1 In the first position, the cooling fluid is located in the tolerance area 140 in the first fluid channel 110 , so that no cooling fluid flows out of the outlet 160 yet.

[0109] Figure 5b Shows that in Figure 3 The third position Figure 4Schematic cross-sectional view of the device along the cutting line AA.

[0110] Here, together with the device 30 to be cooled, here downwardly in the figure, the second fluid channel 120 moves out of the first fluid channel 110, so that the second fluid channel 120 is then only located in the outer tolerance area 150 and the cooling fluid guided in the first fluid channel is discharged or can be discharged to the environment through the outlet 160.

[0111] Figure 6a Shows that in Figure 1 When the first position Figure 4 Schematic cross-sectional view of the device along the cutting line BB.

[0112] In this Figure 6a , the characteristics of the second fluid channel 120 as a multi-port fluid channel are also shown again.

[0113] It can also be seen that the second fluid channel 120 is Figure 1 In the first position, the cooling fluid is located in the tolerance area 140 in the first fluid channel 110 , so that no cooling fluid flows out of the outlet 160 yet.

[0114] Figure 6b Shows that in Figure 3 The third position Figure 4 Schematic cross-sectional view of the device along the cutting line BB.

[0115] It can also be seen here that the second fluid channel 120 has moved out of the first fluid channel 110 together with the device 30 to be cooled, downwardly in the figure, so that the second fluid channel 120 is then only located in the outer tolerance area 150, and the cooling fluid guided in the first fluid channel is discharged or can be discharged to the environment through the outlet 160.

[0116] In summary, these examples show how to provide a seal between two cooling channels with tolerance compensation and overflow behavior.
