Description

[0001] Vehicle electronic module

[0002] The invention relates to a vehicle electronic module.

[0003] From US 10117357 B2, a cooling plate and a vapor chamber for line cooling of one or more circuit boards in a housing for printed circuits (PCB) is known. The cooling plate can comprise a flat surface at an oblique angle in relation to an axis, along which the circuit board assembly is inserted into the housing.

[0004] The invention is based on the object to provide a vehicle electronic module with an improved arrangement for cooling electronic units.

[0005] The object is solved by the subject matters of the independent claims. Advantageous developments of the invention are defined by the dependent claims, the following description as well as the figures.

[0006] A first aspect of the invention relates to a vehicle electronic module with a housing, a first electronic unit and a second electronic unit, a cooling unit and a movement device. The housing is formed for receiving multiple separate electronic units and for receiving at least one separate cooling unit for cooling the electronic units. The first electronic unit and the second electronic unit are detachably arranged in the housing. The cooling unit is arranged in the housing between the first electronic unit and the second electronic unit. By the movement device, a first relative movement between the first electronic unit and the cooling unit can be performed such that the cooling unit is arranged spaced from the first electronic unit in the housing in a first positioning state of the first electronic unit, and the cooling unit and the first electronic unit are pressed onto each other in the housing in a second positioning state of the first electronic unit. By the movement device, a second relative movement between the second electronic unit and the cooling unit can be performed such that the cooling unit is arranged spaced from the second electronic unit in the housing in a first positioning state of the second electronic unit, and the cooling unit and the second electronic unit are pressed onto each other in the housing in a second positioning state of the second electronic unit. The movement device comprises an actuation system. By actuating the actuation system, the first relative movement and / or the second relative movement can be selectively generated. In particular, both the first and the second relative movement or only the first relative movement or only the second relative movement can be generated by the actuation of the actuation system. The first relative movement occurs between the first electronic unit and the cooling unit. The second relative movement occurs between the second electronic unit and the cooling unit.

[0007] Thus, an ensemble of the first and the second electronic unit and the cooling unit is formed, which can be variously movable to each other as intended to flexibly generate various coupling states and decoupling states for adequately cooling.

[0008] In various embodiments, the vehicle electronic module can comprise one or more further ensembles with respectively a further first electronic unit, a further second electronic unit and a further cooling unit. The explanations here and in the following with respect to the ensemble and corresponding embodiments, which are described here and in the following, can optionally be analogously transferred to the further ensembles.

[0009] By the arrangement of the cooling unit between the electronic units, they can be arranged in the housing in space-saving manner. By the possibility of selectively performing the first or the second relative movement by means of the movement device, the first electronic unit and the second electronic unit can be adequately cooled.

[0010] The first positioning state of the first electronic unit can in particular be referred to as decoupled state of the first electronic unit and the second positioning state of the first electronic unit can be referred to as coupled state of the first electronic unit. The first positioning state of the second electronic unit can in particular be referred to as decoupled state of the second electronic unit and the second positioning state of the second electronic unit can be referred to as coupled state of the second electronic unit. For example, the first and the second electronic unit can be in the same, thus in the coupled or in the decoupled, state at the same time. It is also possible that the first electronic unit is in the coupled state and the second electronic unit is in the decoupled state. The positioning state of the respective electronic unit in particular relates to a distance between the cooling unit and the respective electronic unit and is in particular independent on whether the respective electronic unit or the cooling unit is movable. By actuating the actuation system, the positioning state of the first electronic unit and the positioning state of the second electronic unit are for example changed at the same time or offset in time.

[0011] Here and in the following, the first and the second electronic unit together can in particular be referred to as the electronic units.

[0012] In particular, the electronic units and the cooling unit are pressed onto each other with a predefined pressure in the respective second positioning state. In particular, the electronic units can be removed from the housing in the respective first positioning state. Thereby, the electronic units can be exchanged as needed. Thus, a simple exchange of the electronic units, in particular in the respective first positioning state, is allowed, and a high cooling power for cooling the electronic units in the respective second positioning state is allowed at the same time.

[0013] By the actuation of the actuation system, a linear, in particular exclusively linear, movement of one of the electronic units along a vertical axis is in particular initiated. For example, the vertical axis is perpendicular to an insertion direction. The insertion direction is for example a direction, in which the electronic units can be inserted into the housing. Optionally, the electronic units and / or the cooling unit are substantially not movable in a transverse direction perpendicular to the vertical axis and to the insertion direction. In particular, a movement of the electronic units in transverse direction is limited by guide rails. The vertical axis can also be referred to as height direction. In particular, the described movements and their directions can also be inversely performed.

[0014] The electronic units are for example vehicle control devices.

[0015] In an embodiment, the movement device is configured to contact a top side of the cooling unit facing the first electronic unit with the first electronic unit and to contact a second opposing bottom side of the cooling unit facing the second electronic unit with the second electronic unit.

[0016] By this arrangement of the electronic units and the cooling unit, the first electronic unit and the second electronic unit can be cooled in space-saving manner with only a single cooling unit. In an embodiment, a heat transfer element is arranged at the cooling unit on an outer side of the cooling unit facing the first electronic unit. Alternatively or additionally, a heat transfer element is arranged on an outer side of the first electronic unit, which faces the cooling unit.

[0017] In particular, a heat transfer element is arranged at the cooling unit on an outer side of the cooling unit facing the second electronic unit. Alternatively or additionally, a heat transfer element is arranged on an outer side of the second electronic unit, which faces the cooling unit.

[0018] For example, the heat transfer element can be formed as a heat conducting paste and / or as a cooling pad. Thereby, heat arising at the respective electronic unit can be dissipated to the cooling unit in improved manner.

[0019] In particular, a pressing force between the cooling unit and the first electronic unit is greater than a simple contact in the second positioning state of the first electronic unit. Optionally, the pressing force depends on the used heat transfer element. The pressing force can also be referred to as compression force since the cooling pad is for example compressed with a quantity of this force. The compression force to be applied is for example between 400 N and 2500 N for the cooling unit and the first electronic unit. The pressing force between the cooling unit and the second electronic unit in the second positioning state of the second electronic unit is for example equal to the pressing force between the cooling unit and the first electronic unit in the second positioning state of the first electronic unit.

[0020] In an embodiment, the housing comprises guide rails for inserting the first electronic unit and the second electronic unit into the housing such that defined insertion planes spaced from each other are formed for the electronic units.

[0021] It is also possible that the housing comprises further guide rails for inserting into the housing for the cooling unit, in particular only for the cooling unit.

[0022] In particular, the electronic units and / or the cooling unit are arranged parallel on various planes in the housing. The guide rails or further guide rails facilitate receiving and / or removing the electronic units and / or the cooling unit. In an embodiment, the first electronic unit comprises a unit housing, onto which the cooling unit is pressed. In particular, the cooling unit is pressed onto a bottom side of the unit housing of the first electronic unit. In particular, the bottom side of the unit housing faces the cooling unit. Alternatively or additionally, the second electronic unit comprises a further unit housing, onto which the cooling unit is pressed. In particular, the cooling unit is pressed onto a top side of the unit housing of the second electronic unit. In particular, the top side of the further unit housing faces the cooling unit. By the unit housing, the electronic units can be protected from contamination and environmental influences.

[0023] It is possible that the first and / or the second electronic unit, in particular the respective unit housing, comprise a circuit board. For example, the circuit board is thermally coupled to the unit housing via a heat conducting material and a pedestal. Thereby, a direct heat path from the circuit board via the heat conducting material, the pedestal and the unit housing and optionally via a heat transfer element to the cooling unit is formed. Thus, the heat is dissipated in improved manner.

[0024] In an embodiment, the cooling unit is formed as a plate. In particular, the plate is formed to be passed by a cooling fluid. Due to its shape, the plate can respectively extensively contact the electronic units, in particular the unit housings, and thereby dissipate the heat in improved manner.

[0025] It is possible that the cooling unit is cooled by means of a cooling fluid, in particular a cooling liquid. The cooling fluid is for example distributed to the cooling unit via a distributor.

[0026] In an embodiment, the actuation system comprises a single actuating element. For example, the actuating element is formed as a pivot bracket. In this embodiment, the first electronic unit and the second electronic unit can be moved at the same time upon actuation of the actuating element.

[0027] In an embodiment, the relative movement is generated by pivoting the actuating element formed as a pivot bracket in one direction. The pivot bracket can also be referred to as lever. In particular, each one pivot point of the lever is arranged on each one opposing side of the housing. For example, the lever is rotatably attached to the housing at the pivot points. Thereby, it is for example possible that the electronic units are moved parallel to each other and towards each other to the cooling unit during the relative movement. For example, the pivot bracket is formed such that a removal of the first electronic unit is blocked by the pivot bracket if the cooling unit and the electronic units are in the second positioning state. The second positioning state can for example be referred to as closed state. For example, the pivot points of the lever are connected to each other via an axis. By the pivot bracket, it is possible in simplified manner to transfer the cooling unit and the electronic units from the first positioning state into the second positioning state and vice versa.

[0028] In an embodiment, the actuation system comprises multiple separate actuating elements. For example, the actuating elements are formed as a lifting element and mating lifting element.

[0029] In an embodiment, a first actuating element is a lifting element and a second actuating element is a guide unit separate therefrom, which is arranged displaceably to the lifting element. The actuation of the actuation system represents a relative movement of the lifting element to the guide unit in this embodiment.

[0030] In an embodiment, the guide unit is a mating lifting element. For example, the lifting element is a wedge. The mating lifting element can for example be designed as a mating wedge. In particular, the wedge and the mating wedge are shifted against each other to generate the relative movement. In other words, the actuation of the actuation system can be performed by means of a displacement of the lifting element along the mating lifting element. For example, the wedge is movable by rotating screws. Thereby, the pressing force is adjustable in defined manner. Alternatively, the wedge is for example locked in a position along the mating wedge by means of screws.

[0031] For example, the lifting element and the mating lifting element are connected to each other via a transverse element. For example, a displacement of the lifting element with respect to the mating lifting element can be achieved by rotating a screw and by force transfer via the transverse element. Therein, a longitudinal axis of the screw is optionally oriented perpendicularly to the vertical axis. This embodiment of an actuating element can be referred to as clamping device.

[0032] In an embodiment, an actuating element is a pin, which is oriented obliquely to the vertical axis. In other words, the pin is oriented non-parallel and non-perpendicularly to the vertical axis. In particular, the actuation system comprises multiple such pins. For example, the actuation system comprises six pins per electronic unit. In particular, the six pins are positioned in an edge area of the respective electronic unit and directed to a central point of the respective electronic unit.

[0033] It is possible that the pin is formed as a screw and the guide channel is formed as a thread. Thereby, the pressing force can be continuously adjusted. In another example, the pin is formed corrugated such that it forms a snap connection with multiple locking positions with the guide channel. Thereby, a defined pressing force can be adjusted in improved manner.

[0034] A second aspect of the invention relates to a vehicle electronic module with a housing, a first cooling unit and at least one second cooling unit, an electronic unit and a movement device. The housing is formed for receiving at least one separate electronic unit and for receiving multiple separate cooling units for cooling the electronic unit. The first cooling unit and the second cooling unit are detachably arranged in the housing. The electronic unit is arranged in the housing between the first cooling unit and the second cooling unit. By the movement device, a first relative movement between the first cooling unit and the electronic unit can be performed such that the first cooling unit is arranged spaced from the electronic unit in the housing in a first positioning state of the first cooling unit, and the first cooling unit and the electronic unit are pressed onto each other in the housing in a second positioning state of the first cooling unit. By the movement device, a second relative movement between the second cooling unit and the electronic unit can be performed such that the second cooling unit is arranged spaced from the electronic unit in the housing in a first positioning state of the second cooling unit, and the second cooling unit and the electronic unit are pressed onto each other in the housing in a second positioning state of the second cooling unit. The movement device comprises an actuation system. By actuating the actuation system, the first relative movement and / or the second relative movement can be selectively generated.

[0035] In particular, both the first and the second relative movement or only the first relative movement or only the second relative movement can be generated by the actuation of the actuation system.

[0036] With this second aspect of the invention, a cooling power can for example be adequately adjusted. For example, only the first cooling unit is coupled to the electronic unit. For increasing the cooling power, the second cooling unit can then also be coupled to the electronic unit such that the electronic unit is then cooled from two opposing sides. Thus, an ensemble of the first and the second cooling unit and the electronic unit is formed, which can be variously movable to each other as intended to flexibly generate various coupling states and decoupling states for adequately cooling.

[0037] In various embodiments, the vehicle electronic module can comprise one or more further ensembles with each one further first cooling unit, one further second cooling unit and one further electronic unit.

[0038] Embodiments, advantages and features of the vehicle electronic module according to the invention according to the first aspect as well as explanations in this respect can be analogously transferred to the vehicle electronic module of the second aspect of the invention.

[0039] Further features of the invention are apparent from the claims, the figures and the description of figures. The features and feature combinations mentioned above in the description as well as the features and feature combinations mentioned below in the description of figures and / or shown in the figures alone are usable not only in the respectively specified combination, but also in other combinations without departing from the scope of the invention. Thus, implementations are also to be considered as encompassed and disclosed by the invention, which are not explicitly shown in the figures and explained, but arise from and can be generated by separated feature combinations from the explained implementations. Implementations and feature combinations are also to be considered as disclosed, which thus do not comprise all of the features of an originally formulated independent claim. Moreover, implementations and feature combinations are to be considered as disclosed, in particular by the implementations set out above, which extend beyond or deviate from the feature combinations set out in the relations of the claims.

[0048] Fig. 9 a schematic section of a further embodiment of the vehicle electronic module according to the invention.

[0049] In Fig. 1 , an exemplary embodiment of a vehicle electronic module 1 according to the invention within the meaning of the first aspect of the invention is schematically illustrated. The vehicle electronic module 1 comprises a housing 2, at least one first electronic unit 3 and at least one second electronic unit 4, at least one cooling unit 5 and a movement device 7 indicated in outlined manner. In the shown example, two first electronic units 3 and two second electronic units 4 and two cooling units 5 are illustrated. The housing 2 is formed for receiving multiple separate electronic units 3, 4 and for receiving at least one separate cooling unit 5 for cooling the electronic units 3, 4.

[0050] Each cooling unit 5 together with one of the first electronic units 3 and one of the second electronic units 4, between which the respective cooling unit 5 is arranged, can be construed as an ensemble. Unless otherwise mentioned, such an ensemble is described in the following. The first electronic unit 3 is detachably arranged in the housing 2. The cooling unit 5 is arranged in the housing 2 between the first electronic unit 3 and the second electronic unit 4. By the movement device 7, a first relative movement between the first electronic unit 3 and the cooling unit 5 can be performed such that the cooling unit 5 is arranged spaced from the first electronic unit 3 in the housing 2 in a first positioning state of the first electronic unit 3, and the cooling unit 5 and the first electronic unit 3 are pressed onto each other in the housing 2 in a second positioning state of the first electronic unit 3. By the movement device 7, a second relative movement between the second electronic unit 4 and the cooling unit 5 can be performed such that the cooling unit 5 is arranged spaced from the second electronic unit 4 in the housing 2 in a first positioning state of the second electronic unit 4, and the cooling unit 5 and the second electronic unit 4 are pressed onto each other in the housing 2 in a second positioning state of the second electronic unit 4. The movement device 7 comprises an actuation system 9. By actuating the actuation system 9, the first relative movement and the second relative movement can be selectively generated. The first relative movement occurs between the first electronic unit 3 and the first cooling unit 5. The second relative movement occurs between the second electronic unit 4 and the cooling unit 5.

[0051] For example, a bottom side 3a of the first electronic unit 3 can directly contact a top side 5a of the cooling unit 5 in the second positioning state of the first electronic unit 3. In the second positioning state of the first electronic unit 3, the electronic unit 3 is in particular coupled to the cooling unit 5. In the first positioning state of the first electronic unit 3, the electronic unit 3 is decoupled from the cooling unit 5 and thereby spaced from the cooling unit 5.

[0052] In the second positioning state of the second electronic unit 4, a top side 4a of the second electronic unit 4 can for example directly contact a bottom side 5b of the cooling unit 5. Thereby, the electronic unit 4 is in particular coupled to the cooling unit 5 in the second positioning state of the second electronic unit 4. In the first positioning state of the second electronic unit 4, the electronic unit 4 is decoupled from the cooling unit 5 and thereby spaced from the cooling unit 5. In Fig. 1 , the electronic units 3, 4 are exemplarily respectively shown in the decoupled first positioning state.

[0053] For example, the electronic units 3, 4 can each comprise a unit housing 6. Then, the cooling unit 5 can in particular contact a bottom side 3a of the unit housing 6 of the first electronic unit 3 and a top side 4a of the unit housing 6 of the second electronic unit 4. For example, a circuit board 12 can respectively be arranged in the unit housings 6. Optionally, the electronic units 3, 4 are electrically connected to each other via a board connection plug 19.

[0054] Optionally, the cooling unit 5 can be formed as a plate. For example, the plate can be passed by a cooling fluid. In particular, the cooling fluid can be supplied to the plate by means of a distributor 11 .

[0055] Fig. 2 schematically shows a detailed view of the vehicle electronic module 1 . For example, the electronic units are illustrated in the decoupled state in Fig. 2. In the example shown in Fig. 2, the actuation system 9 can comprise multiple individual actuating elements 14. The actuating elements 14 for example each comprise a contact surface 25 for contacting the respective electronic unit 3, 4. By actuation of a first actuating element 14a of the actuating elements 14, the first electronic unit 3 can for example be moved in its lifting direction 13a along a lifting path 22, in particular until the first electronic unit 3 contacts the cooling unit 5 with a predefined pressure. By actuation of a second actuating element 14b of the actuating elements 14, the second electronic unit 4 can for example be moved in its lifting direction 13b along a lifting path 22, in particular until the second electronic unit 4 contacts the cooling unit 5 with a predefined pressure.

[0056] In Fig. 3, an individual actuating element 14 is schematically illustrated in detailed view. For example, the actuating element 14 is designed as a wedge. For example, the wedge comprises a wedge bottom side 28 and a clamping screw 31 . A mating lifting element, which is designed as a mating wedge 27 in Fig. 3, comprises a guide wedge top side 29. The mating wedge 27 can also be referred to as guide wedge. For example, the guide wedge is fixedly connected to the housing 2. The guide wedge top side 29 can directly contact the wedge bottom side 28. By detaching the clamping screw 31 , the wedge can be displaced with respect to the guide wedge. The contact surface 25 of the wedge can directly contact the respective electronic unit 3, 4 to be cooled. In particular, the wedge is displaceable with respect to the housing 2 along its longitudinal axis 15. By displacing the wedge along its longitudinal axis 15, the respective electronic unit 3, 4 can be one- dimensionally displaced in its respective lifting direction 13a, 13b. By tightening the clamping screw 31 , a lifting position and thereby a displacement position of the wedge in relation to the mating lifting element 27 can be fixed. For example, the actuation system 9 shown in Fig. 2 can comprise two, in particular four, in particular six, actuating elements 14 per electronic unit 3, 4. For example, the actuating elements 14 can each be arranged in a corner area 17 (Fig. 4) of the respective electronic unit 3, 4. Additionally or alternatively, actuating elements 14 can for example be arranged on a longitudinal side 20 (Fig. 4) of the respective electronic unit 3, 4.

[0057] Fig. 4 shows a further embodiment of the vehicle electronic module 1 as a top view with a further embodiment of the actuation system 9. In this exemplary embodiment, the actuation system 9 comprises multiple actuating elements 14. The actuating elements 14 in the embodiment shown in Fig. 4 are formed as pins, in particular as screws 16a, 16b. The screws 16a, 16b can contain corner screws 16a and further screws 16b. The corner screws 16a can for example be positioned in the corner areas 17 of the respective electronic unit 3, 4. The corner screws 16a can be oriented obliquely to the respective lifting direction 13a, 13b. In addition, the corner screws 16a can be oriented obliquely towards a central point 18 of the respective electronic unit 3, 4. The further screws 16b can be positioned on the longitudinal side 20 of the respective electronic unit 3, 4.

[0058] In particular, the screws 16a, 16b can be tightened with a predefined torque such that the respective electronic unit 3, 4 is pressed against the cooling unit 5 with a predefined contact pressure.

[0059] In Fig. 5, a schematic frontal view of one of the electronic units 3, 4 with an actuation system 9, in particular with the actuation system 9 illustrated in Fig. 4, is exemplarily shown. The screws 16a can be rotated-in in a rotational direction 21 to move the electronic unit 3, 4 in its respective lifting direction 13a, 13b.

[0060] In Fig. 6, Fig. 7, Fig. 8 and Fig. 9, embodiments of the vehicle electronic module 1 are schematically illustrated. In Fig. 6, Fig. 7 and Fig. 8, the actuation system 9 is only illustrated in outlined manner as lever positions 23a, 23b, 23c of a lever in cross-section. The description to actuations of the lever are in particular to be exemplarily understood for an actuation of the actuation system 9.

[0061] In Fig. 6, the lever is in a central position 23b of the lever positions 23a, 23b, 23c. By actuating the lever along an actuation path 10a to an upper lever position 23a, the first electronic unit 3 can for example be moved to the cooling unit 5 in its movement direction 13a along the lifting path 22a. By actuation of the lever along an actuation path 10b to a lower lever position 23c, the second electronic unit 4 can for example be moved to the cooling unit 5 in its movement direction 13b along the lifting path 22b. By an inverse actuation of the lever along the actuation path 10a, the first electronic unit 3 can in particular be decoupled from the cooling unit 5. By an inverse actuation of the lever along the actuation path 10b, the second electronic unit 4 can in particular be decoupled from the cooling unit 5.

[0062] For example, the first electronic unit 3 and the second electronic unit 4 cannot be coupled to the cooling unit 5 at the same time. In particular, the first electronic unit 3 and the second electronic unit 4 cannot be decoupled from the cooling unit 5 at the same time.

[0063] In the embodiments illustrated in Fig. 6 and Fig. 7, the first electronic unit 3 and the second electronic unit 4 can for example be selectively coupled to the cooling unit 5.

[0064] In Fig. 7, the lever can for example be in the upper lever position 23a. By actuating the lever along the actuation path 10a to the central position 23b, the first electronic unit 3 can for example be moved to the cooling unit 5. By a further actuation of the lever along the actuation path 10b up to the lower lever position 23c, the second electronic unit 4 can be moved to the cooling unit 5. By an inverse actuation of the lever, first the second electronic unit 4 and then the first electronic unit 3 can in particular be decoupled from the cooling unit 5.

[0065] For example, the first electronic unit 3 and the second electronic unit 4 can be coupled to the cooling unit 5 at the same time. In particular, the first electronic unit 3 and the second electronic unit 4 can be decoupled from the cooling unit 5 at the same time. In particular, coupling and / or decoupling are effected offset in time.

[0066] In the embodiment shown in Fig. 8, coupling can for example be effected at the same time for the first electronic unit 3 and the second electronic unit 4 by actuation of the lever from the upper lever position 23a to the lower lever position 23c. In particular, decoupling can also be effected at the same time for the first electronic unit 3 and the second electronic unit 4 by an inverse actuation of the lever from the lower lever position 23c to the upper lever position 23a.

[0067] Fig. 9 shows an embodiment of the vehicle electronic module 1 within the meaning of the second aspect of the invention. In this embodiment, an electronic unit 3 is arranged between two cooling units 5. One or more further electronic units can be optional for this embodiment. In this embodiment, the housing 2 is formed for receiving the electronic unit 3 and for receiving the cooling units 5 for cooling the electronic unit 3. The electronic unit 3 is detachably arranged in the housing 2. The electronic unit 3 is arranged in the housing 2 between cooling units 5. By the movement device, a relative movement between the electronic unit 3 and the cooling units 5 can be performed such that the cooling units 5 are arranged spaced from the electronic unit 3 in the housing 2 in a first positioning state and the cooling units 5 and the electronic unit 3 are pressed onto each other in the housing 2 in a second positioning state. The movement device 7 comprises an actuation system 9. By actuating the actuation system 9, a first relative movement and a second relative movement are selectively generated. The first relative movement occurs between the electronic unit 3 and a first one of the cooling units 5. The second relative movement occurs between the electronic unit 3 and a second one of the cooling units 5. In particular, the embodiments shown in Fig. 1 to Fig. 8 are to be regarded as analogous embodiments for the variant shown in Fig. 9.
