Description

[0001] Vehicle electronic module and method for operating a vehicle electronic module

[0002] The invention relates to a vehicle electronic module and to a method for operating 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. The circuit board assembly can include a vapor chamber with a complementary, obliquely angled surface. The complementarily angled surfaces of the cooling plate and the vapor chamber can exert forces against each other upon inserting the circuit board assembly into the housing and upon contact between the cooling plate and the vapor chamber.

[0004] The invention is based on the object to provide a vehicle electronic module and a method for operating the vehicle electronic module to adequately cool at least two 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] An aspect of the invention relates to a vehicle electronic module with 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 movement device. The housing is formed for receiving multiple separate electronic units and for receiving multiple separate cooling units for cooling the electronic units. The first electronic unit is detachably arranged in the housing. The first cooling unit and the at least one second cooling unit are arranged in the housing. By the movement device, a relative movement between the electronic units and the cooling units can be performed such that the cooling units are arranged spaced from the electronic units in the housing in a first positioning state. In a second positioning state, the cooling units and the electronic units are pressed onto each other in the housing. The movement device comprises at least one actuating element. By actuating the at least one actuating element, both a first relative movement and a second relative movement are generated in an actuation operation 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.

[0007] In the first positioning state, all of the cooling units of the vehicle electronic module in particular are each spaced from all of the electronic units of the vehicle electronic module. Thus, a cooling unit of the vehicle electronic module is not in contact with an electronic unit of the vehicle electronic module. In the second positioning state, at least the first cooling unit is pressed onto the first electronic unit and the second cooling unit is pressed onto the second electronic unit. In the second positioning state, each cooling unit of the vehicle electronic module is preferably pressed onto at least one electronic unit of the vehicle electronic module and each electronic unit of the vehicle electronic module is pressed onto at least one cooling unit of the vehicle electronic module.

[0008] In particular, the actuation operation is a single, in particular contiguous actuation of the at least one actuating element, in particular to be performed from the beginning to the end of the actuation path as intended. The actuation path can for example be a movement path between a start position and an end position of the at least one actuating element. The at least one actuating element can in particular also be referred to as movement element.

[0009] The movement device is in particular configured to respectively change a distance between at least two electronic units to at least two cooling units. In particular, the movement device may also be referred to as a movement mechanism.

[0010] By the actuation of the at least one actuating element, a linear, in particular exclusively linear, movement, in particular of the cooling units, along a vertical axis is in particular initiated. The vertical axis is for example 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 units 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.

[0011] By the vehicle electronic module according to the invention, the electronic units can be adequately cooled. The electronic units are for example vehicle control devices. In particular, the electronic units can be electronic control units, electronic control modules or electronic control unit blades (ECU blades). With only a single actuation of the at least one actuating element, all of the cooling units and electronic units can for example be transferred from the first positioning state into the second positioning state and / or returned. For example, the at least one actuating element is designed as a single actuating element. Alternatively, the at least one actuating element is designed as multiple actuating elements, in particular exactly two actuating elements.

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

[0013] In an embodiment, the first relative movement and the second relative movement are generated at the same time over the same movement path and / or in the same movement direction by the actuation operation.

[0014] In other words, the first relative movement and the second relative movement are synchronously effected. Thereby, it is allowed that, in particular all of, the electronic units are transferred into a cooling mode at the same time in that the electronic units and the cooling units are synchronously moved into the second positioning state. By inverse actuation of the at least one actuating element, in particular all of, the electronic units can be prepared to disassembly at the same time in that the electronic units are detached from the cooling units.

[0015] It is possible that the movement directions of the cooling units are different. For example, all of the cooling units can be moved at the same time, wherein each two of the cooling units are moved towards each other and diverge from each other in opposite direction upon inverse actuation of the at least one actuating element. This is in particular advantageous in arrangements, in which two cooling units are arranged between two electronic units. Therein, two cooling units and two electronic units are for example alternating ly arranged one above the other in height direction in the housing. For example, each two cooling units can also be located between each pair of two electronic units. Thereby, the electronic units are coolable from two opposing sides by means of the cooling units. It is possible that the movement directions of the cooling units and / or of the electronic units are identical. Thereby, mechanics of the movement device can be simplified, in particular compared to a movement of the cooling units and / or electronic units towards each other or opposite.

[0016] The movement path is for example the actuation path. A movement direction is for example either upwards or downwards.

[0017] In an embodiment, the first relative movement by the actuation of the at least one actuating element along a first partial path of the actuation path and the second relative movement by actuation of the at least one actuating element along a second partial path of the actuation path can be performed offset in time. In particular, the second partial path is different from the first partial path and adjoins to the first partial path.

[0018] In other words, the second relative movement is effected offset in time to the first relative movement. For example, the first cooling unit is moved by actuation of the at least one actuating element along the first partial path and the second cooling unit is moved by actuation of the at least one actuating element along the second partial path. In particular, not all of the cooling units and electronic units are transferred from the second positioning state into the first positioning state at the same time. Thereby, the electronic units can for example be individually removed, in particular without the further electronic units interrupting a contact with the respective cooling units.

[0019] In an embodiment, the at least one actuating element can be locked in a transition between the first partial path and the second partial path. In other words, the at least one actuating element is fixable in the transition in self-sustaining manner. Thereby, the removal of a subset of the electronic units, in particular of an individual electronic unit, is for example possible in simplified manner.

[0020] In an embodiment, the cooling units and the electronic units are in particular each oriented parallel to each other during the respective relative movement to each other. Thereby, the cooling units and the electronic units can be arranged in the housing in space-saving manner. In particular, distances between the cooling unit and the electronic unit to be cooled with this cooling unit are identical in the first and / or in the second positioning state for all of the cooling units to the respective electronic unit. Optionally, the advantage results from it that simpler mechanics can be used for the movement device since only a linear movement and in particular respectively an identical lift of the cooling units and / or the electronic units are performed.

[0021] In an embodiment, at a cooling unit, which is intended for contacting with an electronic unit, a heat transfer element is arranged on an outer side facing the electronic unit. Alternatively or additionally, a heat transfer element is arranged on an outer side of the electronic unit, which faces the cooling unit to be contacted. In particular, the heat transfer element can be formed as a thermal interface material or thermal gap filler. 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 electronic unit can be dissipated to the cooling unit in improved manner.

[0022] In particular, a pressing force between the cooling unit and the electronic module in the second positioning state is greater than a simple contact. 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 first cooling unit and the first electronic unit. For embodiments, in which all of the relative movements are performed by a single actuation by means of a single actuation operation, a compression force is optionally required, which corresponds to the multiple of the number of electronic units or cooling units to be moved. For example, the compression force for three cooling units to be moved at the same time is between 1200 N and 7500 N.

[0023] In an embodiment, the housing comprises guide rails for inserting the electronic units, in particular exclusively for the electronic units, into the housing, such that defined insertion planes spaced from each other are formed for the electronic units.

[0024] It is also possible that the housing comprises further guide rails for the cooling units for inserting into the housing such that defined insertion planes spaced from each other are formed for the cooling units.

[0025] In particular, the electronic units and / or the cooling units are arranged parallel on different planes in the housing. The guide rails facilitate receiving and / or removing the electronic units and / or the cooling units.

[0026] In an embodiment, the first cooling unit and the second cooling unit are coupled in terms of movement by a connecting element of the movement device. In particular, the first cooling unit and the second cooling unit are rigidly connected to each other spaced from each other by the connecting element. Thereby, a simultaneous movement of, in particular all of, the cooling units in the same movement direction is simply allowed. For example, a movement of the connecting element is limited by a stop element. In particular, the stop element is a part of the housing, in particular a housing bottom or a housing lid.

[0027] In an embodiment, the connecting element is formed as a sliding panel, which encloses an end area of each of the at least two cooling units. In particular, the sliding panel is a panel element arranged at the housing for example on the end face, which is slidable with respect to the housing. In particular, the movement device comprises two opposing sliding panels. For example, the sliding panel is guided within a groove. By this embodiment, tilting of the cooling units is in particular prevented such that they remain parallel to the electronic units during the relative movements.

[0028] It is possible that the cooling units are cooled by means of a cooling fluid. The cooling fluid is for example distributed to the cooling units via a manifold. In such an embodiment, the manifold can be formed as a connecting element.

[0029] The connecting element can for example also be formed as a rod, for example, as a connector or fittings.

[0030] By the connecting element, it is for example possible that the first and the second relative movement are performed by means of a single actuation operation.

[0031] In an embodiment, the first electronic unit comprises a unit housing, onto which the first cooling unit is pressed. In particular, the first 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 first cooling unit. Alternatively or additionally, the second electronic unit comprises a further unit housing, onto which the second cooling unit is pressed. In particular, the bottom side of the further unit housing faces the second cooling unit. The electronic units can be protected from contamination and environmental influences by the unit housing.

[0032] It is possible that the electronic unit, in particular the unit housing, comprises 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 respective cooling unit is formed. Thus, the heat is dissipated in improved manner.

[0033] In an embodiment, the cooling units are formed as plates. In particular, the plates are formed to be passed by a cooling fluid. Due to their shape, the plates can each extensively contact the electronic units, in particular the unit housings, and thereby dissipate the heat in improved manner.

[0034] In an embodiment, the actuation operation is formed as pivoting an actuating element formed as a pivot bracket of the at least one actuating element 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. The lever is for example rotatably attached to the housing at the pivot points. Thereby, it is for example possible that the cooling units are moved parallel to the electronic units during the relative movement to each other. 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 units 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, in particular by means of a single actuation operation, to transfer the cooling units and electronic units from the first positioning state into the second positioning state and vice versa.

[0035] In an embodiment, an actuating element of the at least one actuating element is a lifting element. The lifting element is displaceably arranged at a guide unit separate therefrom. By an actuation path in an actuation operation, the at least two relative movements between the electronic units and the cooling units are generated. The actuation operation represents a relative movement of the lifting element to the guide unit.

[0036] 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 movements. In other words, the actuation operation can be performed by means of a displacement of the lifting element along the mating lifting element. The wedge is for example 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 the screws.

[0037] 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 the actuating element can be referred to as clamping device.

[0038] In an embodiment, a contact surface of the lifting element, by which the lifting element is contacted with the connecting element for generating the relative movement, is parallel to the insertion planes.

[0039] In an embodiment, an actuating element of the at least one actuating element is a screw, which is oriented parallel to the vertical axis. For example, the screw is arranged centrally at the housing. In particular, the screw is coupled in terms of movement to the connecting element. In an embodiment, at least each two screws are arranged at each of the sliding panels.

[0040] A further aspect of the invention relates to a method for operating a vehicle electronic module according to the invention. Therein, a cooling mode for the electronic units is adjusted. Thereto, the at least one actuating element is actuated along the actuation path. Thereby, both the first relative movement between the first electronic unit and the first cooling unit as well as the second relative movement between the second electronic unit and the second cooling unit are generated. In the first relative movement, the first cooling unit and the first electronic unit are transferred from a decoupled state into a coupled state. In the second relative movement, the second cooling unit and the second electronic unit are transferred from a decoupled state into a coupled state. Thereby, the first and the second electronic unit can for example be cooled.

[0041] In an embodiment, a disassembly mode is adjusted. Thereto, the at least one actuating element is moved inversely to the adjustment of the cooling mode. Thereby, both a first further relative movement between the first electronic unit and the first cooling unit and a second further relative movement between the second electronic and the second cooling unit are generated. In the first further relative movement, the first cooling unit and the first electronic unit are transferred from a coupled state into a decoupled state. In the second further relative movement, the second cooling unit and the second electronic unit are transferred from a coupled state into a decoupled state. Thereby, the first and the second electronic unit can for example be removed.

[0042] In particular, the vehicle electronic module according to the invention is formed for performing a method according to the invention. In particular, the vehicle electronic module according to the invention performs the method according to the invention.

[0043] Further embodiments of the method according to the invention immediately follow from the different configurations of the vehicle electronic module according to the invention and vice versa. In particular, individual features and corresponding explanations as well as advantages with respect to the different embodiments to the vehicle electronic module according to the invention can be analogously transferred to corresponding embodiments of the method according to the invention.

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.

[0055] Fig. 8 a schematic longitudinal section of a further embodiment of the vehicle electronic module according to the invention. Fig. 1 schematically shows an exemplary embodiment of a vehicle electronic module 1 according to the invention. The vehicle electronic module 1 comprises a housing 2, a first electronic unit 3 and at least one second electronic unit 4, three second electronic units 4 in the shown example, a first cooling unit 5 and at least one second cooling unit 6, two second cooling units 6 in the shown example, and a movement device 7. The housing 2 is formed for receiving multiple separate electronic units 3, 4 and for receiving multiple separate cooling units 5, 6 for cooling the electronic units 3, 4. The first electronic unit 3 is detachably arranged in the housing 2. In particular, the electronic units 3, 4, are insertable into the housing 2 in z-direction via guide rails 8. The first cooling unit 5 and the at least one second cooling unit 6 are arranged in the housing 2. A relative movement between the electronic units 3, 4 and the cooling units 5, 6 can be performed by the movement device 7 such that the cooling units 5, 6 and the electronic units 3, 4 are pressed onto each other in the housing 2 in a second positioning state. The second positioning state can be referred to as closed state. For example, the closed state is shown in Fig. 1 .

[0056] The first positioning state is exemplarily shown in Fig. 3a and can be referred to as opened state. Therein, the first electronic unit 3 is in particular decoupled from the first cooling unit 5 and the second electronic unit 4 is decoupled from the second cooling unit 6.

[0057] The movement device 7 comprises an actuating element 9. This actuating element 9 can be a rod. The rod can be gripped by a user. By actuation of the actuating element 9, both a first relative movement and a second relative movement are generated in an actuation operation along an actuation path 10 (Fig. 2). 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 second cooling unit 6.

[0058] For example, the cooling units 5, 6 can be passed by a cooling fluid for cooling the electronic units 3, 4. Thereto, the cooling fluid can optionally be distributed to the cooling units 5, 6 via a manifold 11 . In particular, the cooling units 5, 6 can be formed as plates. In particular, the plates can be arranged parallel to each other and to the electronic units 3, 4.

[0059] For example, the vehicle electronic module 1 comprises a first connecting element 12a and a second connecting element 12b. For example, the connecting elements 12a, 12b can be slid along a guide groove 13. The connecting elements 12a, 12b can be formed as a first sliding panel and as a second sliding panel. In particular, the cooling devices 5, 6 are each fixedly connected in the respective connecting element 12a, 12b on the end face. The actuating element 9 is for example designed as a pivot bracket in Fig. 1 . The pivot bracket for example comprises each one pivot point 14 on each one end face 15 of the housing 2. In particular, the pivot bracket comprises each a first leg 16a, a second leg 16b and a third leg 16c on both end faces 15. Upon actuation of the pivot bracket along the actuation path 10, the first leg 16a rotates around the pivot point 14 such that the rotation is translated into a movement in y-direction via the second leg 16b and the third leg 16c. In particular, the pivot point 14 can be immovable in relation to the housing 2.

[0060] The three legs 16a, 16b, 16c are hinged to each other at hinge points 20, 21 . The actuating element 9 is furthermore pivotably mounted at a pivot point 9a. The pivot point 9a is arranged stationary relative to the housing 2.

[0061] In Fig. 2, a further embodiment of the vehicle electronic module 1 is shown as a sectional representation.

[0062] Heat conducting elements 17 can be attached between the electronic units 3, 4 and the respective cooling units 5, 6. In particular, the heat conducting element 17 is arranged directly on a bottom side 3a of the electronic unit 3. In the second position state, the heat conducting element 17 can directly contact a top side 5a of the cooling element 5 facing the bottom side 3a. A connection board 18 can be electrically connected to the electronic units 3, 4 via board connection plugs 19, such that the electronic units 3, 4 can be electrically connected to each other. In particular, the board connection plugs 19 can be designed as board-to-board connectors, a cable connection, a ribbon cable and / or flexible board connection.

[0063] In this embodiment, the connecting element 12a can be formed as a cooling fluid distribution tube or as a rod of the housing 2.

[0064] By actuating the actuating element 9 along the actuation path 10 the electronic units 3, 4 and the cooling units 5, 6 can be transferred from the first positioning state into the second positioning state.

[0065] In Fig. 3a, Fig. 3b and Fig. 3c, a transition from the first positioning state in Fig. 3a to the second positioning state in Fig. 3c is schematically illustrated based on an embodiment. Therein, the vehicle electronic module 1 is illustrated as a schematic cross-section. For example, Fig. 3a shows the first positioning state, Fig. 3b shows a transition from the first positioning state into the second positioning state and Fig. 3c shows the second positioning state.

[0066] In Fig. 3a, the first electronic unit 3 is spaced from the first cooling unit 5 by a lifting path 22. In particular, the second electronic unit 4 and the second cooling unit 6 are also spaced from each other by the lifting path 22 in the first positioning state. In Fig. 3a, Fig. 3b and Fig. 3c, the actuating element 9 is exemplarily illustrated as a pivot bracket in cross-section.

[0067] In Fig. 3b, the actuating element 9 was moved by a first partial path 10a to an intermediate position along the actuation path 10. For example, the lifting path 22 can halve itself compared to the situation shown in Fig. 3a if the actuating element 9 has traveled half of the actuation path 10. In particular, an exclusively linear movement of the cooling units 5, 6 in y-direction, for example a height direction, can be initiated by the actuation of the actuating element 9. Therein, a top side 5a of the first cooling unit 5 moves towards the first electronic unit 3. A 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, in particular directly contact the top side 5a. Alternatively or additionally, the heat conducting element 17 can be directly contacted on the bottom side 3a of the first electronic unit 3. The explanation to the first cooling unit 3 and to the first electronic unit 5 can analogously apply to the second electronic unit 4 and the second cooling unit 6, in particular to all of the further cooling units and electronic units of the vehicle electronic module 1 .

[0068] In Fig. 3c, the electronic units 3, 4 and the cooling units 5, 6 are in the second positioning state. In the second positioning state, the top side 5a contacts the bottom side 3a in direct manner or via the heat conducting element 17. Thereto, the actuating element 9 was moved from the intermediate position in Fig. 3b to an end position along a second partial path 10b of the actuation path.

[0069] In Fig. 4, Fig. 5 and Fig. 6, alternative embodiments of the actuating element 9 are exemplarily illustrated.

[0070] In Fig. 4, the actuating element 9 can directly contact the connecting element 12a via the contact surface 25 of the actuating element 9. In Fig. 4, the actuating element 9 can be formed as a lifting element. The lifting element can be actuated by rotating a screw 26. Optionally, the relative movement can be limited by a housing bottom 2a of the housing 2 and / or a housing lid 2b of the housing 2.

[0071] In Fig. 4, the electronic units 3, 4 and the cooling units 5, 6 are in the second positioning state. In the second positioning state, a clearance 23 is between the connecting element 12a and the housing bottom 2a. The clearance 23 in particular arises by lifting the connecting element 12a by the lifting path 22. An upper edge 24 of the connecting element 12a directly contacts the housing lid 2b in the second positioning state. In this embodiment, the housing lid 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.

[0072] In Fig. 5, an analogously functioning actuating element 9 as a lifting element like in Fig. 4 is shown in detail. By rotating in the screw 26 (Fig. 4) not illustrated in Fig. 5, the lifting element can be moved parallel to the y-direction and in x-direction at the same time. Thereby, the contact surface 25 and thus the connecting element 12a can be moved in y- direction. The lifting element can also be arranged, in particular additionally arranged, on the opposing end face 15.

[0073] By rotating in the screw 26, the lifting element displaces with respect to a fixed mating lifting element 27 separate therefrom.

[0074] In Fig. 6, the actuating element 9 is designed as a wedge. For example, the wedge comprises a wedge bottom side 28 and a clamping screw 31 . The mating lifting element, which is designed as a mating wedge 27 in Fig. 6, 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 bottom 2a. The guide wedge top side 29 directly contacts 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 directly contacts a connecting element bottom side 30 of the connecting element 12a. In particular, the wedge is displaceable in z-direction with respect to the connecting element 12a. By displacing the wedge in z-direction, the connecting element 12a can be one-dimensionally displaced in height direction. By displacing the connecting element 12a, the cooling units 5, 6 are also displaced in height direction. By tightening the clamping screw 31 , a height position and thereby a displacement position of the wedge in relation to the mating lifting element 27 can be fixed. In Fig. 7a, Fig. 7b and Fig. 8, the vehicle electronic module 1 is schematically illustrated in a longitudinal section.

[0075] In an embodiment shown in Fig. 7a, two cooling units 5, 6 can be arranged between the two electronic units 3, 4. For example, the cooling units 5, 6 can diverge from each other by actuation of the actuating element 9 and therein move along the lifting path 22 towards the respective electronic unit 3, 4. By actuation of the actuating element 9, the first cooling unit 5 and the second cooling unit 6 can for example be selectively moved. By traveling the first partial path 10a, the first cooling unit 5 can in particular be moved, and by traveling the second partial path 10b, the second cooling unit 6 can be moved. However, it is also possible that the cooling units 5, 6 are moved at the same time. Therein, the traveled lifting path 22 can in particular be proportional to the traveled actuation path.

[0076] In Fig. 7b, the, in particular two, electronic units 3, 4 are arranged between the cooling units 5, 6. In the transition from the first positioning state into the second positioning state, the cooling units 5, 6 can be moved from the outside towards each other in the direction of the electronic units 3, 4. Therein, the cooling unit bottom side 5b moves towards an electronic unit top side 3b facing it.

[0077] In an embodiment schematically illustrated in Fig. 8, the cooling units 5, 6 can be firmly fixed in the housing with respect to their height position. For contacting the electronic units 3, 4 with the cooling units 5, 6, the electronic units 3, 4 can be linearly moved towards the cooling units 5, 6 in height direction in this embodiment. This embodiment can analogously comprise features from the preceding embodiments of Fig. 1 to Fig. 7b.
