Description

Technical Field

[0001] This invention relates to a vehicle electronic module and a method for operating the vehicle electronic module. Background Technology

[0002] A cooling plate and a vapor chamber are known from US 10117357 B2 for cooling lines of one or more circuit boards in a housing of a printed circuit board (PCB). The cooling plate may include a flat surface angled relative to an axis along which the circuit board assembly is inserted into the housing. The circuit board assembly may include a vapor chamber having complementary angled surfaces. The complementary angled surfaces of the cooling plate and the vapor chamber may exert forces on each other when the circuit board assembly is inserted into the housing and when they come into contact. Summary of the Invention

[0003] The purpose of this invention is to provide a vehicle electronic module and a method for operating the vehicle electronic module to adequately cool at least two electronic units.

[0004] This objective is achieved through the subject matter of the independent claims. Advantageous developments of the invention are defined by the dependent claims, the following description, and the accompanying drawings.

[0005] This invention relates to a vehicle electronic module comprising a housing, a first electronic unit and at least one second electronic unit, a first cooling unit and at least one second cooling unit, and a motion device. The housing is configured to receive a plurality of individual electronic units and a plurality of individual cooling units for cooling the electronic units. The first electronic unit is detachably disposed within the housing. The first cooling unit and at least one second cooling unit are disposed within the housing. The motion device enables relative movement between the electronic unit and the cooling unit, such that the cooling unit is spaced apart from the electronic unit within the housing in a first positioning state. In a second positioning state, the cooling unit and the electronic unit are pressed against each other within the housing. The motion device includes at least one actuating element. By actuating the at least one actuating element, not only a first relative movement but also a second relative movement is generated during actuation along an actuation path. The first relative movement occurs between the first electronic unit and the first cooling unit. The second relative movement occurs between the second electronic unit and the second cooling unit.

[0006] In the first positioning state, all cooling units of the vehicle electronic module are specifically spaced apart from all electronic units of the vehicle electronic module. Therefore, the cooling units of the vehicle electronic module do not contact the electronic units of the vehicle electronic module. In the second positioning state, at least the first cooling unit is pressed against the first electronic unit and the second cooling unit is pressed against the second electronic unit. In the second positioning state, each cooling unit of the vehicle electronic module preferably presses against at least one electronic unit of the vehicle electronic module, and each electronic unit of the vehicle electronic module preferably presses against at least one cooling unit of the vehicle electronic module.

[0007] Specifically, the actuation operation is a single (particularly continuous) actuation of at least one actuating element, particularly executed as intended from the start point to the end point of an actuation path. The actuation path can, for example, be a motion path between the start and end positions of at least one actuating element. The at least one actuating element may also be referred to in particular as a motion element.

[0008] The motion device is particularly configured to change the spacing between at least two electronic units and at least two cooling units respectively. In particular, the motion device may also be referred to as a motion mechanism.

[0009] By actuating at least one actuating element, a linear, and especially purely linear, movement is caused, particularly of the cooling unit, along a vertical axis. The vertical axis is, for example, perpendicular to the insertion direction. The insertion direction is, for example, the direction in which the electronic unit can be inserted into the housing. Optionally, the electronic unit and / or the cooling unit is substantially immobile in a lateral direction perpendicular to the vertical axis and the insertion direction. In particular, the movement of the electronic unit in the lateral direction is restricted by guide rails. The vertical axis may also be referred to as the height direction. In particular, the described movement and its direction can also be performed in reverse.

[0010] The vehicle electronic module according to the invention provides for adequate cooling of the electronic units. These electronic units are, for example, vehicle control devices. Specifically, the electronic units can be electronic control units, electronic control modules, or electronic control unit blades (ECU blades). With only a single actuation of at least one actuating element, all cooling units and electronic units can, for example, transition from a first positioning state to a second positioning state and / or return. For example, at least one actuating element is designed as a single actuating element. Alternatively, the at least one actuating element can be configured as multiple actuating elements, particularly exactly two actuating elements.

[0011] Specifically, the electronic unit and the cooling unit are pressed against each other with a predetermined pressure in the second positioning state. Specifically, the electronic unit can be removed from the housing in the first positioning state. Thus, the electronic unit can be replaced as needed. Therefore, simple replacement of the electronic unit is particularly permitted in the first positioning state, while simultaneously allowing high cooling power for cooling the electronic unit in the second positioning state.

[0012] In one embodiment, an actuation operation simultaneously generates a first relative motion and a second relative motion on the same motion path and / or in the same motion direction.

[0013] In other words, the first relative movement and the second relative movement are achieved synchronously. This allows, in particular, all electronic units to simultaneously switch to cooling mode, as the electronic units and cooling units move synchronously to the second positioning state. Disassembly can be prepared simultaneously by reversing the actuation of at least one actuating element, in particular all electronic units, by removing the electronic units from the cooling units.

[0014] The cooling units can move in different directions. For example, all cooling units can move simultaneously, wherein when at least one actuating element is actuated in the opposite direction, each pair of cooling units moves toward each other and deviates from each other in opposite directions. This is particularly advantageous in arrangements where two cooling units are arranged between two electronic units. In this arrangement, the two cooling units and two electronic units are arranged in the housing, for example, alternating one above the other in the height direction. For example, each pair of cooling units can also be located between each pair of electronic units. Thus, the electronic units can be cooled from two opposite sides by means of the cooling units.

[0015] The cooling unit and / or electronic unit can move in the same direction. This simplifies the mechanical structure of the motion device, especially compared to the cooling unit and / or electronic unit moving toward each other or in opposite directions.

[0016] The path of motion is, for example, an actuation path. The direction of motion is, for example, upward or downward.

[0017] In one embodiment, a first relative movement by actuating at least one actuating element along a first portion of the actuation path and a second relative movement by actuating at least one actuating element along a second portion of the actuation path can be performed at different times. Specifically, the second portion of the path is different from and adjacent to the first portion of the path.

[0018] In other words, the second relative movement occurs at a time offset from the first relative movement. For example, the first cooling unit moves by actuating at least one actuating element along a first partial path, while the second cooling unit moves by actuating at least one actuating element along a second partial path. In particular, not all cooling units and electronic units simultaneously transition from the second positioning state to the first positioning state. Thus, for example, electronic units can be removed individually, especially when other electronic units do not interrupt contact with their respective cooling units.

[0019] In one embodiment, at least one actuating element can be locked in the transition region between the first partial path and the second partial path. In other words, at least one actuating element can be fixed in the transition region in a self-sustaining manner. Thus, for example, a subset of electronic units, particularly a single electronic unit, can be removed in a simplified manner.

[0020] In one embodiment, the cooling unit and the electronic unit are oriented parallel to each other, respectively, during their respective relative movements. This allows the cooling unit and the electronic unit to be arranged in a space-saving manner within the housing. Specifically, in the first and / or second positioning states, the distance between the cooling unit and the corresponding electronic unit is the same for all cooling units to the corresponding electronic unit. Optionally, the resulting advantage is that a simpler mechanism can be used for the motion device, since only linear movement of the cooling unit and / or electronic unit is performed, and in particular, the same lifting is performed respectively.

[0021] In one embodiment, at the cooling unit for contact with the electronic unit, a heat transfer element is arranged on the outer side facing the electronic unit. Alternatively or additionally, a heat transfer element is arranged on the outer side of the electronic unit facing the cooling unit to be contacted. In particular, the heat transfer element can be formed as a thermal interface material or a thermal gap filler. For example, the heat transfer element can be formed as thermally conductive paste and / or a cooling pad. Thus, the heat generated at the electronic unit can be dissipated to the cooling unit in an improved manner.

[0022] Specifically, in the second positioning state, the clamping force between the cooling unit and the electronic module is greater than that of simple contact. Optionally, the clamping force depends on the heat transfer element used. The clamping force can also be called a compressive force, as the cooling pad is compressed by a certain amount of this force, for example. For the first cooling unit and the first electronic unit, the compressive force to be applied is, for example, between 400 N and 2500 N. For embodiments where all relative movements are performed by a single actuation operation, a compressive force equivalent to a multiple of the number of electronic or cooling units to be moved may be optionally required. For example, the compressive force required to move three cooling units simultaneously is between 1200 N and 7500 N.

[0023] In one embodiment, the housing includes guide rails for inserting electronic units, particularly those specifically designed for electronic units, into the housing, such that defined insertion planes spaced apart from each other are formed for the electronic units.

[0024] Alternatively, the housing may include additional guide rails for inserting the cooling unit into the housing, such that defined insertion planes spaced apart from each other are formed for the cooling unit.

[0025] Specifically, the electronic units and / or cooling units are arranged in parallel on different planes within the housing. Guide rails facilitate the reception and / or removal of the electronic units and / or cooling units.

[0026] In one embodiment, the first cooling unit and the second cooling unit are kinematically connected by a connecting element of the motion mechanism. Specifically, the first and second cooling units are rigidly connected to each other spaced apart by the connecting element. This allows for simple simultaneous movement of the cooling units, particularly all cooling units, in the same direction of movement. For example, the movement of the connecting element is restricted by a stop element. Specifically, the stop element is part of the housing, particularly the bottom of the housing or the housing cover.

[0027] In one embodiment, the connecting element is formed as a sliding panel that surrounds the end region of each of at least two cooling units. Specifically, the sliding panel is a panel element disposed at the housing (e.g., on an end face) and is slidable relative to the housing. In particular, the motion device includes two opposing sliding panels. For example, the sliding panels are guided within recesses. This embodiment specifically prevents the cooling units from tilting, ensuring they remain parallel to the electronic units during relative movement.

[0028] The cooling unit can be cooled by a cooling fluid. The cooling fluid is distributed to the cooling unit, for example, via a manifold. In such an embodiment, the manifold can be formed as a connecting element.

[0029] Connecting elements can also be formed as rods, for example, as connectors or fittings.

[0030] The first and second relative motions can be performed by connecting elements, for example, by a single actuation operation.

[0031] In one embodiment, the first electronic unit includes a unit housing onto which a first cooling unit is pressed. The first cooling unit is particularly pressed against the bottom side of the unit housing of the first electronic unit. Specifically, the bottom side of the unit housing faces the first cooling unit. Alternatively or additionally, the second electronic unit includes a separate unit housing onto which a second cooling unit is pressed. Specifically, the bottom side of the separate unit housing faces the second cooling unit. The unit housing protects the electronic unit from contamination and environmental impact.

[0032] It is possible that the electronic unit, particularly the unit housing, includes a circuit board. For example, the circuit board is thermally coupled to the unit housing via a thermally conductive material and a base. This creates a direct heat transfer path from the circuit board through the thermally conductive material, the base, and the unit housing, and optionally through heat transfer elements to the corresponding cooling unit. Consequently, heat is dissipated in an improved manner.

[0033] In one embodiment, the cooling unit is formed as a plate. In particular, the plate is formed to allow the cooling fluid to pass through. Due to their shape, the plates can each make extensive contact with the electronic units, especially the unit housing, thereby dissipating heat in an improved manner.

[0034] In one embodiment, the actuation operation is configured to pivot the actuating element, which is configured as at least one actuating element, in one direction. The pivoting element may also be referred to as a lever. In particular, each pivot point of the lever is arranged on each opposite side of the housing. The lever is rotatably attached to the housing, for example, at the pivot point. Thus, for example, it is possible for the cooling unit to move parallel to the electronic unit during relative movement. For example, the pivoting element is configured such that if the cooling unit and the electronic unit are in a second positioning state, the pivoting element prevents the removal of the first electronic unit. The second positioning state may be referred to, for example, as a closed state. For example, the pivot points of the lever are connected to each other by a shaft. With the pivoting element, the cooling unit and the electronic unit can be transferred from the first positioning state to the second positioning state and vice versa in a simplified manner, particularly by a single actuation operation.

[0035] In one embodiment, the actuating element in at least one actuating element is a lifting element. The lifting element is displaceably arranged at a guide unit separate from it. During the actuation stroke in the actuation process, at least two relative movements are generated between the electronics unit and the cooling unit. The actuation operation represents the relative movement of the lifting element relative to the guide unit.

[0036] In this embodiment, the guiding unit is a mating lifting element. For example, the lifting element is a wedge. The mating lifting element can be designed, for example, to mat with a wedge. Specifically, the wedge and the mating wedge are displaced relative to each other to produce relative movement. In other words, the actuation operation can be performed by means of the lifting element along the displacement of the mating lifting element. The wedge can be moved, for example, by rotating a screw. Therefore, the pressing force can be adjusted in a defined manner. Alternatively, the wedge can be locked in a position along the mating wedge, for example, by means of a screw.

[0037] For example, the lifting element and the mating lifting element are connected to each other via a transverse element. For example, the displacement of the lifting element relative to the mating lifting element can be achieved by rotating the screw and by force transmission via the transverse element. The longitudinal axis of the screw may optionally be oriented perpendicular to the vertical axis. This embodiment of the actuating element can be referred to as a clamping device.

[0038] In one embodiment, the contact surface of the lifting element is parallel to the insertion plane, and the lifting element contacts the connecting element through this contact surface to generate relative motion.

[0039] In one embodiment, the actuating element in at least one actuating element is a screw oriented parallel to a vertical axis. For example, the screw is centrally located at the housing. Specifically, the screw is kinematically coupled to a connecting element. In one embodiment, at least two screws are arranged at each sliding panel.

[0040] Another aspect of the invention relates to a method for operating a vehicle electronic module according to the invention. In this method, the cooling mode of the electronic unit is adjusted. Additionally, at least one actuating element is actuated along an actuation path. This generates not only a first relative movement between the first electronic unit and the first cooling unit, but also a second relative movement between the second electronic unit and the second cooling unit. In the first relative movement, the first cooling unit and the first electronic unit transition from a decoupled state to a coupled state. In the second relative movement, the second cooling unit and the second electronic unit transition from a decoupled state to a coupled state. This allows, for example, cooling of both the first and second electronic units.

[0041] In one embodiment, the disassembly mode is adjusted. To do this, at least one actuating element is moved in the opposite direction to the adjusted cooling mode. This results in not only a first further relative movement between the first electronic unit and the first cooling unit, but also a second further relative movement between the second electronic unit and the second cooling unit. In the first further relative movement, the first cooling unit and the first electronic unit transition from a coupled state to a decoupled state. In the second further relative movement, the second cooling unit and the second electronic unit transition from a coupled state to a decoupled state. Thus, for example, the first electronic unit and the second electronic unit can be removed.

[0042] Specifically, the vehicle electronic module according to the invention is configured to perform the method according to the invention.

[0043] Other embodiments of the method according to the invention follow different configurations of the vehicle electronic module according to the invention, and vice versa. Specifically, the various features, corresponding explanations, and advantages of the different embodiments of the vehicle electronic module according to the invention can be similarly transferred to the corresponding embodiments of the method according to the invention.

[0057] Figure 1 An embodiment of a vehicle electronic module 1 according to the present invention is illustrated schematically. The vehicle electronic module 1 includes a housing 2, a first electronic unit 3 and at least one second electronic unit 4 (three second electronic units 4 in the illustrated example), a first cooling unit 5 and at least one second cooling unit 6 (two second cooling units 6 in the illustrated example), and a motion device 7. The housing 2 is configured to accommodate multiple individual electronic units 3, 4 and multiple individual cooling units 5, 6 for cooling the electronic units 3, 4. The first electronic unit 3 is detachably arranged in the housing 2. Specifically, the electronic units 3, 4 can be inserted into the housing 2 in the z-direction via guide rails 8. The first cooling unit 5 and at least one second cooling unit 6 are arranged in the housing 2. Relative movement between the electronic units 3, 4 and the cooling units 5, 6 can be performed by the motion device 7, such that the cooling units 5, 6 and the electronic units 3, 4 are pressed against each other in a second positioning state within the housing 2. The second positioning state can be referred to as a closed state. For example, Figure 1 The closed state is shown in the figure.

[0058] The first positioning state is Figure 3a The example is shown and may be referred to as the open state. In particular, the first electronic unit 3 is decoupled from the first cooling unit 5, and the second electronic unit 4 is decoupled from the second cooling unit 6.

[0059] The motion device 7 includes an actuating element 9. This actuating element 9 can be a lever. The lever can be gripped by a user. Actuation of the actuating element 9 causes movement along the actuation path 10 during the actuation process. Figure 2 This generates not only a first relative motion but also a second relative motion. The first relative motion occurs between the first electronic unit 3 and the first cooling unit 5. The second relative motion occurs between the second electronic unit 4 and the second cooling unit 6.

[0060] For example, cooling units 5 and 6 can be used to cool the cooling fluid passing through electronic units 3 and 4. Furthermore, the cooling fluid can optionally be distributed to cooling units 5 and 6 via manifold 11. Specifically, cooling units 5 and 6 can be formed as plates. In particular, the plates can be arranged parallel to each other and parallel to electronic units 3 and 4.

[0061] For example, the vehicle electronic module 1 includes a first connecting element 12a and a second connecting element 12b. For example, connecting elements 12a and 12b can slide along a guide groove 13. Connecting elements 12a and 12b can be formed as a first sliding panel and a second sliding panel. Specifically, cooling devices 5 and 6 are fixedly connected to the corresponding connecting elements 12a and 12b on their end faces, respectively. The actuating element 9, for example, is located in... Figure 1 The housing 2 is configured as a pivot support. The pivot support includes, for example, each pivot point 14 on each end face 15 of the housing 2. Specifically, the pivot support includes a first leg 16a, a second leg 16b, and a third leg 16c on both end faces 15. When the pivot support is actuated along the actuation path 10, the first leg 16a rotates about the pivot point 14, such that the rotation is converted into movement in the y-direction via the second leg 16b and the third leg 16c. Specifically, the pivot point 14 may be immovable relative to the housing 2.

[0062] The three legs 16a, 16b, and 16c are hinged to each other at hinge points 20 and 21. Furthermore, the actuating element 9 is pivotally mounted at pivot point 9a. Pivot point 9a is fixedly arranged relative to the housing 2.

[0063] exist Figure 2 Another embodiment of the vehicle electronic module 1 is shown in the cross-sectional view.

[0064] A heat-conducting element 17 can be attached between electronic units 3 and 4 and corresponding cooling units 5 and 6. Specifically, the heat-conducting element 17 is directly disposed on the bottom side 3a of electronic unit 3. In a second position, the heat-conducting element 17 can directly contact the top side 5a of the cooling element 5 facing the bottom side 3a. A connecting plate 18 can be electrically connected to electronic units 3 and 4 via a board connector 19, allowing electronic units 3 and 4 to be electrically connected to each other. Specifically, the board connector 19 can be designed as a board-to-board connector, cable connection, ribbon cable, and / or flexible board connection.

[0065] In this embodiment, the connecting element 12a may be formed as a cooling fluid distribution pipe or as a rod of the housing 2.

[0066] By actuating the actuating element 9 along the actuation path 10, the electronic units 3 and 4 and the cooling units 5 and 6 can switch from the first positioning state to the second positioning state.

[0067] exist Figure 3a , Figure 3b and Figure 3c The diagram illustrates, based on one embodiment, a method for... Figure 3a The first positioning state in Figure 3c The transition to the second positioning state. The vehicle electronic module 1 is illustrated as a schematic cross-section. For example, Figure 3aThe first positioning state is shown. Figure 3b The transition from the first positioning state to the second positioning state is shown, and Figure 3c The second positioning state is shown.

[0068] exist Figure 3a In this configuration, the first electronic unit 3 is spaced apart from the first cooling unit 5 via a lifting path 22. Specifically, the second electronic unit 4 and the second cooling unit 6 are also spaced apart from each other via the lifting path 22 in the first positioning state. Figure 3a , Figure 3b and Figure 3c In the cross-section, the actuating element 9 is exemplarily shown as a pivot bracket.

[0069] exist Figure 3b In the process, the actuating element 9 moves along the actuation path 10, completing a first portion of the path 10a to reach the intermediate position. For example, if the actuating element 9 has traveled halfway along the actuation path 10, then... Figure 3a Compared to the situation shown, the lifting path 22 can be halved. Specifically, the cooling units 5 and 6 can be initiated by actuation of the actuating element 9, resulting in purely linear movement in the y-direction (e.g., the height direction). The top side 5a of the first cooling unit 5 moves towards the first electronic unit 3. The bottom side of the first electronic unit 3 faces the top side 5a of the first cooling unit 5. Optionally, the heat-conducting element 17 can be located on the top side 5a of the first cooling unit 5, particularly in direct contact with the top side 5a. Alternatively or additionally, the heat-conducting element 17 can directly contact the bottom side 3a of the first electronic unit 3. The explanation of the first cooling unit 3 and the first electronic unit 5 can be similarly applied to the second electronic unit 4 and the second cooling unit 6, particularly to all other cooling units and electronic units of the vehicle electronic module 1.

[0070] exist Figure 3c In the middle, electronic units 3 and 4 and cooling units 5 and 6 are in a second positioning state. In the second positioning state, the top side 5a contacts the bottom side 3a directly or via the heat-conducting element 17. Furthermore, the actuating element 9 travels along the second portion of the actuation path 10b from... Figure 3b The middle position is moved to the end position.

[0071] exist Figure 4 , Figure 5 and Figure 6 An alternative embodiment of the actuator 9 is shown in the example.

[0072] exist Figure 4 In this configuration, the actuating element 9 can directly contact the connecting element 12a through its contact surface 25. Figure 4 In this configuration, the actuating element 9 can be configured as a lifting element. The lifting element can be actuated by rotating the screw 26.

[0073] Alternatively, relative movement may be limited by the housing bottom 2a of housing 2 and / or the housing cover 2b of housing 2.

[0074] exist Figure 4 In this configuration, electronic units 3 and 4 and cooling units 5 and 6 are in a second positioning state. In this second positioning state, a gap 23 exists between the connecting element 12a and the housing bottom 2a. This gap 23 is specifically created by lifting the connecting element 12a via a lifting path 22. The upper edge 24 of the connecting element 12a directly contacts the housing cover 2b in the second positioning state. In this embodiment, the housing cover 2b serves as an upper stop for the connecting element 12a, and the housing bottom 2a serves as a lower stop for the connecting element 12a.

[0075] exist Figure 5 The text details the connection between the two. Figure 4 Similarly, the actuating element 9 functions as a lifting element. Through... Figure 5 Screw 26 (not shown) Figure 4 The lifting element can rotate within the contact surface 25, and thus the connecting element 12a can move in the y-direction and simultaneously in the x-direction. Consequently, the contact surface 25 and therefore the connecting element 12a can move in the y-direction. The lifting element can also be arranged, particularly additionally, on the opposing end face 15.

[0076] By screwing in screw 26, the lifting element is displaced relative to the fixed-fit lifting element 27 that is separated from it.

[0077] exist Figure 6 In this configuration, the actuating element 9 is configured as a wedge. For example, the wedge includes a bottom side 28 and a clamping screw 31. Figure 6 The mating lifting element designed to mate with wedge 27 includes a guide wedge top side 29. The mating wedge 27 can also be referred to as a guide wedge. For example, the guide wedge is fixedly connected to the bottom 2a of the housing. The guide wedge top side 29 directly contacts the wedge bottom side 28. By removing the clamping screw 31, the wedge can be displaced relative to the guide wedge. The contact surface 25 of the wedge directly contacts the connecting element bottom side 30 of the connecting element 12a. Specifically, the wedge can be displaced relative to the connecting element 12a in the z-direction. By displacing the wedge in the z-direction, the connecting element 12a can be displaced one-dimensionally in the height direction. By displacing the connecting element 12a, the cooling units 5 and 6 are also displaced in the height direction. By tightening the clamping screw 31, the height position of the wedge relative to the mating lifting element 27 can be fixed, thereby fixing the displacement position.

[0078] exist Figure 7a , Figure 7b and Figure 8 The vehicle electronic module 1 is schematically shown in a longitudinal section.

[0079] exist Figure 7a In the illustrated embodiment, two cooling units 5 and 6 can be arranged between two electronic units 3 and 4. For example, cooling units 5 and 6 can be actuated by actuation of actuation element 9 and move along lifting path 22 toward the respective electronic units 3 and 4. By actuation of actuation element 9, the first cooling unit 5 and the second cooling unit 6 can be selectively moved, for example. The first cooling unit 5 can be moved by traveling along the first partial path 10a, and the second cooling unit 6 can be moved by traveling along the second partial path 10b.
