Description

[0001] The present invention relates to a thermal management module for a motor vehicle, in particular for a battery-electric motor vehicle.

[0002] Particularly in battery-electric vehicles, thermal management modules can be used for efficient thermal management. Such a thermal management module can include a fluid block for distributing or collecting a primary thermal fluid, which has several primary fluid ports for supplying or discharging the primary thermal fluid. The thermal management module can also be equipped with several valves for controlling the primary fluid ports, as well as several sensors for measuring the pressure or temperature of the primary thermal fluid at different primary fluid ports. Furthermore, such a thermal management module can include a heat exchanger configured for heat transfer and media separation between the primary and secondary thermal fluids. Depending on the fluid circuit, the respective thermal fluid can be a coolant or a refrigerant.Within the thermal management module, the heat exchanger and the fluid block are fluidically and mechanically connected via fluid connections. Depending on the system pressure in the respective fluid circuit, these fluid connections can be subjected to high mechanical stresses. At the same time, such a thermal management module should be as compact as possible.

[0003] The present invention addresses the problem of providing an improved embodiment for a thermal management module of the type described above, which is characterized in particular by a compact design, while at the same time ensuring sufficient tightness and / or mechanical strength even for higher system pressures.

[0004] This problem is solved according to the invention by the subject matter of the independent claim. Advantageous embodiments are the subject matter of the dependent claims.

[0005] The invention is based on the general concept of realizing a fluid connection between the fluid block and the heat exchanger using a connecting element that, on the one hand, mechanically fastens the heat exchanger to the fluid block and, on the other hand, enables the desired fluidic connection between a first fluid port of the fluid block and a second fluid port of the heat exchanger. The dual function of the connecting element allows for an extremely compact design for the respective fluid connection, which in turn allows the thermal management module as a whole to be built compactly. This is all the more true the more fluid connections are provided on the thermal management module and realized using such a connecting element.

[0006] Specifically, the invention proposes a thermal management module comprising a fluid block for distributing or collecting a first thermofluid, several first fluid ports formed on the fluid block, at least one valve for controlling one of the first fluid ports, at least one sensor for measuring the pressure or temperature of the first thermofluid, a heat exchanger for heat-transferring, media-separated coupling of the first thermofluid with a second thermofluid, and at least one second fluid port formed on the heat exchanger, which is attached to one of the first fluid ports for transferring the first thermofluid by means of a fluid connection. Each fluid connection has an elongated connecting element whose longitudinal axis defines an axial direction, a radial direction, and a circumferential direction. The axial direction extends parallel to the longitudinal axis.The radial direction extends transversely to the axial direction and can, in particular, be perpendicular to the longitudinal center axis. The circumferential direction revolves around the longitudinal center axis. The respective connecting element penetrates the first fluid port in the area of ​​a first channel formed at the first fluid port, which carries the first thermofluid, and is screwed to the second fluid port in the area of ​​a second channel formed at the second fluid port, which also carries the first thermofluid. This screw connection secures the first fluid port to the second fluid port.

[0007] Furthermore, the connecting element is configured to fluidically connect the first channel to the second channel.

[0008] In the present context, a “configuration” is synonymous with a “design” and / or “setup”, so that the phrase “configured so that” is synonymous with the phrase “designed and / or set up so that”.

[0009] According to an advantageous embodiment, the connecting element can be hollow, so that the first channel is fluidically connected to the second channel through the connecting element. This results in an extremely compact fluid connection.

[0010] According to an advantageous embodiment, the connecting element can contain a cavity and have an axial opening at a first longitudinal end, which is open axially to the cavity and to the second channel. In other words, the cavity is fluidically connected to the second channel through the axial opening. The connecting element can have a coupling section axially spaced from the first longitudinal end, which has at least one radial opening that is open radially to the cavity and to the first channel. In other words, the cavity and the first channel are fluidly connected to each other through the respective radial opening. The cavity passes coaxially through the coupling section.

[0011] In particular, it can be provided that the coupling section is arranged in the first fluid connection such that an annular space is formed radially between the first fluid connection and the connecting element, circumferentially, which is fluidically connected on the one hand to the first channel and on the other hand to the respective radial opening, so that the first channel is fluidically connected to the cavity through the annular space and through the respective radial opening.

[0012] In an advantageous embodiment, the connecting element can have a threaded section axially spaced from the coupling section. This threaded section has its first longitudinal end and an external thread radially on its outer surface. The second fluid connection can have a threaded opening open to the second channel, which has an internal thread. The threaded section can then be screwed into the internal thread of the threaded opening with its external thread. The cavity extends coaxially through the threaded section. This results in a screw connection that is coaxial with the fluid connection, which contributes to a compact design.

[0013] According to another embodiment, the connecting element can have a sealing section axially between the threaded section and the coupling section. This sealing section comprises a circumferentially circulating first ring seal, which radially seals against the first fluid connection, and a circumferentially circulating second ring seal, which is axially spaced from the first ring seal and radially seals against the second fluid connection. Ring seals ensure sufficient sealing even at high pressures. Radially acting ring seals also allow for simplified axial assembly.

[0014] According to an advantageous embodiment, the first ring seal and / or the second ring seal may be made of EPDM, i.e., ethylene propylene diene monomer rubber, or of HNBR, i.e., hydrogenated acrylonitrile butadiene rubber. EPDM is particularly suitable for R-744 as a refrigerant. HNBR is particularly suitable for R-744 and R-290 as refrigerants.

[0015] According to an advantageous embodiment, the sealing section may have a first annular groove for receiving the first ring seal, which has an axial groove width, and an axial end facing the coupling section, which is axially spaced from the first annular groove. The threaded section has an axial thread length which, according to a particularly advantageous configuration, is greater than the sum of the groove width and the axial space. This design ensures that the connecting element can be unscrewed sufficiently to be securely held on the heat exchanger while simultaneously allowing pressure relief in the first thermofluid.

[0016] In another advantageous embodiment, the second fluid connection may have a cylindrical section in the area of ​​the second ring seal that transitions axially into the threaded opening via a circumferentially circumferential annular shoulder. The sealing section may transition into the threaded section via a circumferentially circumferential annular collar. In the assembled state, the annular collar can bear axially against the annular shoulder, allowing the connecting element to be screwed almost flush with the second fluid connection. Alternatively, the annular collar may be spaced axially from the annular shoulder. In this case, the first fluid connection can be securely screwed to the second fluid connection, so that the first fluid connection comes into axial contact with the second fluid connection, particularly directly within the fluid connection.It is conceivable that a surface seal is arranged axially between the first fluid connection and the second fluid connection, which may in particular be configured as a metal seal.

[0017] In another advantageous embodiment, the first fluid connection may have an axial through-opening that is radially open to the first channel. The connecting element may extend axially through the through-opening and may be axially closed at a second longitudinal end located axially away from the first longitudinal end. In other words, the second longitudinal end of the connecting element closes the internal cavity axially relative to the axial opening located at the first longitudinal end. Furthermore, the connecting element may have a closure section on a side of the coupling section located axially away from the first longitudinal end. This closure section comprises the second longitudinal end and axially closes the through-opening. The closure section acts like a lid or cover to close the through-opening.The high degree of integration of the connecting element supports the compact design for the fluid connection and thus for the entire thermal management module.

[0018] The closure section may expediently have a third ring seal running circumferentially, which radially seals against the first fluid connection.

[0019] Furthermore, the locking section can have a torque transmission contour axially on the outside and / or radially on the outside for introducing a torque to screw in or unscrew the locking element.

[0020] According to an advantageous embodiment, the third ring seal can be made of EPDM (ethylene propylene diene monomer rubber) or HNBR (hydrogenated acrylonitrile butadiene rubber). EPDM is particularly suitable for use with R-744 as a refrigerant. HNBR is particularly suitable for use with both R-744 and R-290 as refrigerants.

[0021] In another embodiment, the first fluid connection may have an annular step surrounding the through-opening, wherein the closure section has a circumferentially circumferential, radially projecting collar that rests axially against the annular step. Through direct contact between the closure element and the first fluid connection via the collar supported on the annular step, the first fluid connection can be axially pre-tensioned against the second fluid connection by means of the screw connection created by the connecting element.

[0022] The third ring seal can, in particular, bear axially against the collar, thus positioning it axially. The ring step can be aligned with the closure section in such a way that the closure section is recessed, in particular flush-mounted, within the ring step in the first fluid connection.

[0023] In an advantageous configuration, the first thermofluid can be a refrigerant, while the second thermofluid is preferably a coolant. In this case, the heat exchanger can be configured as a chiller, enabling heat transfer between the refrigerant and the coolant. For example, R-744 (carbon dioxide, CO2) or R-290 (propane, C3H8) can be used as the refrigerant.

[0024] The sealing material for the first ring seal and / or for the second ring seal and / or for the third ring seal can be an ethylene propylene diene rubber, i.e. an EPDM, or a hydrogenated acrylonitrile butadiene rubber, i.e. an HNBR, whereby EPDM and HNBR are advantageous in conjunction with the refrigerant R-744, while HNBR is advantageous in conjunction with the refrigerant R-290.

[0025] A preferred embodiment is one in which the fluid block is configured as a distribution block for the first thermofluid. Alternatively, a configuration of the fluid block as a collector block is also conceivable.

[0026] In another advantageous embodiment, the thermal management module can have a module carrier to which the fluid block and the heat exchanger are attached.

[0027] Further important features and advantages of the invention will become apparent from the dependent claims, the drawings and the associated description of the figures based on the drawings.

[0028] It is understood that the features mentioned above and those to be explained below can be used not only in the combinations specified, but also in other combinations or individually, without departing from the scope of the invention as defined by the claims. Components of a higher-level unit, such as a device, apparatus, or arrangement, mentioned above and those to be mentioned below, which are designated separately, can form separate parts or components of this unit or be integral areas or sections of this unit, even if this is depicted differently in the drawings.

[0029] Preferred embodiments of the invention are shown in the drawings and are explained in more detail in the following description, wherein identical reference numerals refer to identical or similar or functionally identical components.

[0030] They show, schematically, Fig. 1. An isometric view of a thermal management module, Fig. 2 Another isometric view of the thermal management module, but from a different viewing direction than in Fig. 1, Fig. 3 a highly simplified sectional view through a fluid connection of the thermal management module, Fig. 4 a longitudinal section through a connecting element of the fluid connection, Fig. 5 a side view of the connecting element.

[0031] According to the Fig. 1 and Fig. 2 comprises a thermal management module 1, which can be used in a motor vehicle, in particular a battery-electric motor vehicle, a fluid block 2 for distributing or collecting a first thermal fluid 3, which is contained in the Fig. 1 to 3 are indicated by arrows. With the aid of the fluid block 2, the thermal management module 1 can be fluidically integrated into a thermal system (not shown here), in particular that of a motor vehicle, which may have at least one thermal circuit, in particular a cooling circuit or refrigeration circuit, as well as other components.

[0032] The thermal management module 1 also has several first fluid connections 4 formed on the fluid block 2, through which the first thermofluid 3 can be supplied or discharged. The thermal management module 1 also has several valves 5 for controlling the first fluid connections 4. Each valve 5 has an electrical control connection 6 for actuating the respective valve 5. Furthermore, the thermal management module 1 is equipped with several sensors 7 configured to measure temperature or pressure in the first thermofluid 3. The signals generated by each sensor 7, which correlate with the measured pressure or temperature value, can be accessed via electrical connections 8.

[0033] The thermal management module 1 is also equipped with a heat exchanger 9, which is used for heat-transferring, media-separated coupling of the first thermofluid 3 with a second thermofluid 10, which is located in the Fig. 1 and Fig. 2 is indicated by arrows. The heat exchanger 9 has at least one, and preferably two, second fluid connections 11, which are, however, concealed here and accordingly in Fig. 1 are indicated only by broken reference lines. The two second fluid connections 11 expediently form an inlet connection for supplying the first thermofluid 3 to the heat exchanger 9 and an outlet connection for removing the first thermofluid 3 from the heat exchanger 9. The second fluid connections 11 of the heat exchanger 9 are each connected by means of a Fig. The fluid connection 12, shown in simplified form, is rigidly connected to one of the first fluid ports 4 for transferring the first thermofluid 3. In other words, each fluid connection 12 is configured to mechanically fix and fluidically connect one of the first fluid ports 4 to one of the second fluid ports 11.

[0034] Accordingly Fig. 3 Each fluid connection 12 has a connecting element 13 which is additionally located in the Fig. 4 and Fig. 5 is shown in isolation. The connecting element 13 is configured elongated, so that it has a longitudinal center axis 14. The longitudinal center axis 14 defines an axial direction X that extends parallel to the longitudinal center axis 14 and into the Fig. 3 to 5 is indicated by a double arrow. The longitudinal center axis 14 also defines a radial direction R, which is in the Fig. 3 to 5 are each indicated by a double arrow and run perpendicular to the axial direction X and, in particular, are perpendicular to the longitudinal center axis 14. Furthermore, the longitudinal center axis 14 defines a circumferential direction U, which in the Fig. 3 to 5 is indicated by a double arrow and revolves around the longitudinal center axis 14.

[0035] The connecting element 13 penetrates according to Fig. The connecting element 13 connects the first fluid connection 4 in the area of ​​a first channel 15, which is formed in the first fluid connection 4 and carries the first thermofluid 3. The connecting element 13 is also screwed to the second fluid connection 11 in the area of ​​a second channel 16, which is formed in the second fluid connection 11 and carries the first thermofluid 3. Thus, the connecting element 13 fastens the first fluid connection 4 to the second fluid connection 11. Furthermore, the connecting element 13 is configured to fluidically connect the first channel 15 to the second channel 16.

[0036] According to the Fig. From 3 to 5, the connecting element 13 is designed to be hollow, so that it contains a cavity 17. In this way, the first channel 15 can be fluidically connected to the second channel 16 through the connecting element 13. The connecting element 13 has a first longitudinal end 18, which extends into the Fig. The connecting element 13, located at points 3 to 5 on the right, has an axial opening 19 that is open axially to the cavity 17 and the second channel 16. The cavity 17 thus communicates with the second channel 16 through the axial opening 19. Axially spaced from the first longitudinal end 18, the connecting element 13 has a coupling section 20 that has at least one radial opening 21, which is open radially to the cavity 17 and the first channel 15. Thus, the cavity 17 communicates with the first channel 15 through the respective radial opening 21. In the example shown, the coupling section 20 has four radial openings 21 that are uniformly distributed in the circumferential direction U.Furthermore, in the example shown, a circumferentially closed annular space 22 is formed radially between the coupling section 20 and the first fluid connection 4, so that the cavity 17 is fluidically connected to the first channel 15 through this annular space 22 via all radial openings 21 distributed in the circumferential direction U. It is also provided that, to form the annular space 22, the connecting element 13 in the area of ​​the coupling section 20 has a reduced outer cross-section.

[0037] In the example shown here, the connecting element 13 has a threaded section 23 axially spaced from the coupling section 20. This threaded section has a first longitudinal end 18 and a radially external external thread 24. Complementing this, the second fluid connection 11 has a threaded opening 25 open to the second channel 16, which has an internal thread 26 that matches the external thread 24. The threaded section 23 is screwed into the internal thread 26 of the threaded opening 25 via the external thread 24.

[0038] Furthermore, the connecting element 13 has a sealing section 27 axially between the threaded section 23 and the coupling section 20, which comprises a first ring seal 28 and a second ring seal 29. The first ring seal 28 extends circumferentially U and radially seals against the first fluid port 4. The second ring seal 29 extends circumferentially U, is axially spaced from the first ring seal 28, and radially seals against the second fluid port 11.

[0039] The second fluid connection 11 has a cylindrical section 30 in the area of ​​the second ring seal 29, which transitions axially into the threaded opening 25 via an annular shoulder 31 circumferentially U. The sealing section 27 transitions into the threaded section 23 via an annular collar 32 circumferentially U. In the example of the Fig. In the 3 annular collar 32 rests axially against the annular shoulder 31. In another embodiment, the connecting element 13, the first fluid connection 4, and the second fluid connection 11 can be arranged such that the annular collar 32 is axially spaced from the annular shoulder 31. Optionally, an axially projecting sealing collar 43 can be formed on the annular collar 32, which is configured to plastically deform when the connecting element 13 is screwed in with a predetermined tightening torque, thereby forming an additional seal. In the example shown, the sealing collar 43 is formed radially outside the annular collar 32. Advantageously, the threaded section 23 has, according to Fig. 4 an axial thread length of 44.

[0040] According to Fig. The first fluid connection 4 has an axial through-opening 33, which is radially open to the first channel 15. The connecting element 13 passes through this through-opening 33 and is axially closed at a second longitudinal end 34 that is axially opposite the first longitudinal end 18. In other words, the cavity 17 extending coaxially within the connecting element 13 is open at the first longitudinal end 18 and closed at the second longitudinal end 34. The connecting element 13 also has a closing section 35, which is located on a side of the coupling section 20 that is axially opposite the first longitudinal end 18 and which has the second longitudinal end 34 and is configured to axially close the through-opening 33. The closing section 35 may have a third annular seal 36 that runs circumferentially U and bears radially against the first fluid connection 4.The first fluid port 4 can have an annular step 37 that surrounds the through-opening 33. The closure section 35 can have a circumferentially U-shaped, radially projecting collar 38 that bears axially against the annular step 37. As a result, when the closure element 13 is screwed into the second fluid port 11, it presses the first fluid port 4 axially against the second fluid port 11. In this example, the third ring seal 36 is axially supported by the collar 38. Fig. 3. In the fluid connection 12, the first fluid port 4 is located directly adjacent to the second fluid port 11. In another embodiment, not shown here, a flat gasket (not shown here) can be arranged axially between the first fluid port 4 and the second fluid port 11, by means of which the first fluid port 4 and the second fluid port 11 indirectly support each other.

[0041] For positioning the first ring seal 28, a first annular groove 39 circumferentially U-directed can be formed on the sealing section 27. For positioning the second ring seal 29, a second annular groove 40 circumferentially U-directed can be formed on the sealing section 27, into which the second ring seal 29 is inserted. The first annular groove 39 has, according to Fig. 4 has an axial groove width 45 and an axial distance 47 from the coupling section 20 or from an axial end 46 of the sealing section 27 facing the coupling section 20. This axial distance 47 and the groove width 45 together form an axial sealing length 48 that the connecting element 13 has relative to the fluid block 2. A preferred configuration is one in which the thread length 44 is greater than the sealing length 48. This allows pressure relief in the fluid system to be achieved by slowly unscrewing the connecting element 13, without the risk of the connecting element 13 being blown out by the system pressure beforehand.

[0042] Advantageously, the first thermofluid 3 can be a refrigerant, while the second thermofluid 10 can be a coolant. Advantageously, the heat exchanger 9 can then be configured as a chiller, which facilitates heat transfer between the refrigerant (i.e., the first thermofluid 3) and the coolant (i.e., the second thermofluid 10). Advantageously, the fluid block 2 can be configured as a distribution block for distributing the first thermofluid 3 to the heat exchanger 9 and to other components and / or at least one thermoelectric circuit of the thermal system.

[0043] According to Fig. The thermal management module 1 can also be equipped with a module carrier 41, to which both the fluid block 2 and the heat exchanger 9 are attached. The module carrier 41 also serves to hold other components and connections of the thermal management module 1.

[0044] According to Fig.2. The heat exchanger 9 can have two third fluid connections 42, through which the second thermofluid 10 can be supplied to and discharged from the heat exchanger 9.

[0045] The design of the connecting element 13 presented here is particularly advantageous because it allows for a reduction in space by simultaneously providing fluid guidance and sealing via the connecting element 13. Higher dimensional tolerances are only required to a very limited extent. Centering is ensured by the round, cylindrical, or circular-cylindrical design. Consequently, only a very small area of ​​a few millimeters on the connecting element 13 needs to be machined to a specific fit. Similarly, only relatively short areas on the mating components, i.e., the fluid block 2 and the heat exchanger 9, require a fit. In addition, there are the three areas for the three ring seals 28, 29, and 36, namely the sealing section 35 and the two annular grooves 39 and 40, but these are only present on the connecting element 13. The quality of the fit depends exclusively on the design criteria for the ring seals 28, 29, and 36.whose contact contours on the connecting element 13, i.e., the annular grooves 39, 40 and the sealing section 35, are defined. This makes the design largely independent of the considerable pressures at R-744, since the pressure acts axially and not radially. For the sealing effect, only the desired compression of the ring seals 28, 29, 36 in the respective annular groove 39, 40 or on the sealing section 35 is decisive. Since these are round fits, they are particularly cost-effective to manufacture. The alignment, in particular the centering of the components, takes place during assembly and without the need for centering pins, as is common with other connecting elements.
