[Technical field]

[0001] The invention relates to an electric ventilator for a temperature control device of an electronic computer, the electric ventilator having a housing in which an electric ventilator of the electric ventilator is arranged and an electric contact device arranged to contact a further electric contact device of the electronic computer, the contact device arranged to transfer at least electric energy from the electronic computer to the electric ventilator.Furthermore, the invention relates to an installation for an electronic computer, as well as to an electronic computer. [Background technology]

[0002] From the prior art, electric ventilators are already known which are formed as part of a temperature control device for an electronic computer. In particular, in the corresponding operation of the electronic computer, for example thermal energy, in particular heat, is generated. In order to obtain a higher power of the electronic computer, this heat needs to be dissipated via the corresponding temperature control device. For example, it can be envisaged that the temperature control device comprises corresponding cooling fins which absorb thermal energy and release it into the surrounding environment of the electronic computer. In order that an even better heat dissipation can be performed by the temperature control device, the electric ventilator can be arranged to blow air through the cooling fins. This allows the dissipation of heat to the surrounding environment of the cooling fins via the blown air to be performed. Thus, a more effective cooling of the electronic computer can be achieved. Summary of the Invention

[0003] An object of the present invention is to provide an electric ventilator, equipment, and electronic computer that realizes a reduction in the labor required for assembly.

[0004] This object is achieved by an electric ventilator, an installation as well as an electronic computer according to the independent claims. Advantageous configurations are specified in the dependent claims. An aspect of the invention is an electric ventilator for a temperature control device of an electronic computer, the electric ventilator having a housing in which an electric ventilation device of the electric ventilator is arranged and an electric contact device arranged to contact a further electric contact device of the electronic computer, the contact device being arranged to transfer at least electric energy from the electronic computer to the electric ventilation device.

[0005] It is envisaged that the housing comprises a shaft which is configured to fit in a certain area into a recess corresponding to the shaft in a further housing of the electronic computer, and the contact device is fixed within the shaft and configured to be in direct wireless contact with the further contact device.

[0006] Thus, a reduction in the effort involved in assembling the electric ventilator to the further housing of the computer is realized. For this purpose, it can in particular be realized that when the electric ventilator is mounted, the electric ventilator is brought into direct contact with the further housing. By means of the direct contact, a manual plug-in connection and contact of the electric ventilator to, for example, the computer does not have to be plugged in. This allows, for example, an automatic assembly process of the electric ventilator to the further housing to be realized.

[0007] In other words, it is envisaged that when the electric ventilator is mounted, the shaft is inserted into the recess and there is brought into direct contact with the further contact device immediately during or at least after the plugging-in procedure. Thus, there is no need to additionally carry out a process of connecting or plugging in the contact device to the further contact device, in particular manually. By plugging the shaft into the recess and the fixed contact device, contact can be realised immediately in the plugging-in process.

[0008] In particular, the shaft is formed as a hollow cylinder. The contact device is fixed inside the hollow shaft, in other words the contact device is formed in the interior space of the shaft. In particular, the contact device is fixed to the inner surface of the shaft, for example by screwing.

[0009] For example, the temperature control device may be provided with a plurality of, in particular two or more, cooling ribs or cooling fans. In particular, an electric ventilator may generate an air flow by blowing air towards the temperature control device. This may ensure good cooling of the electronic computer, since the air may absorb the heat of the temperature control device. For example, an improvement in the computing power of the electronic computer may be achieved by good cooling.

[0010] The contact device can be fixed in the shaft, for example, via a screw. Furthermore, the contact device can be fixed in the shaft via a corresponding adhesive connection or a clamping device. The contact device can also be injection molded onto the shaft.

[0011] Preferably, the temperature control device is formed to cool the electronic computer, however, it is also conceivable that heating of the electronic computer is realized by the temperature control device.

[0012] According to a further advantageous form of configuration, the electric ventilation device comprises a first circuit board on which at least one electrical component for the electric ventilation device is formed, and the contact device comprises a second circuit board fixed to the shaft. The contact device is therefore formed in particular on a circuit board, which may also be referred to as a printed circuit board (PCB). For example, corresponding contact elements for the contacts may be formed on the second circuit board. The second circuit board is fixed in particular in the hollow shaft. Furthermore, the ventilation device comprises a first circuit board, which may comprise corresponding circuits, for example for the control of the electric ventilation device. In particular, the first circuit board is formed in the interior space of the housing and the second circuit board is formed in the interior space of the shaft in the housing.

[0013] Furthermore, it has proven to be advantageous if the first circuit board and the second circuit board are connected to one another in a wired manner. Possible movements between the first circuit board and the second circuit board can thus be compensated for, in particular, by a wired connection. The wired connection is in particular a flexible wired connection. This allows shocks during the operation of the vehicle to be reliably absorbed, for example if the electronic calculator is to be formed in a vehicle.

[0014] It is further advantageous if the contact device is formed to transmit control signals from the electronic computer to the electric ventilation device in addition to the transmission of electric energy. For example, a speed control, for example a rotation speed, for the electric ventilation device can be transmitted as a control signal to the electric ventilation device. In this way, the control of the electric ventilation device can be performed in particular via the electronic computer. By plugging in the electric ventilation device, the contact for both the energy transmission and the transmission of the control signal can thus be performed directly. The rotation speed of the electric ventilation device can thus be adapted in a manner adapted, for example, to the computing performance of the electronic computer and the heat generated therefrom. A reliable operation of the electronic computer can thus be realized with little assembly effort on the further housing of the electric ventilation device.

[0015] In a further advantageous form of configuration, the contact device comprises at least two contact elements, in particular at least four contact elements, and the further contact device comprises at least two, in particular at least four contact elements corresponding to the contact elements. For example, two contact elements are formed to transmit electric energy. The first contact element may represent, for example, a positive electrode and the second contact element may represent a negative electrode. In a form of configuration with four contact elements, it may be particularly envisaged that at least a third contact element of the contact elements and at least a fourth contact element of the contact elements serve to transmit a control signal. Thus, both energy and control signals can be reliably transmitted on the basis of direct contact between the contact elements. This may significantly reduce the assembly effort, since it is particularly unnecessary to manually place the electric ventilator in the further housing and correspondingly manually contact it in order to transmit both electric energy and control signals from the electronic computer to the electric ventilator.

[0016] Furthermore, it has proven to be advantageous if at least one of the contact elements of the contact device or of the further contact device is formed as a leaf spring contact element. In particular, the contact element of the further contact device can be formed as a contact element corresponding to the leaf spring contact element. On the basis of the leaf spring contact element, it becomes possible to ensure that the contact between the contact device and the further contact device can be achieved, in particular when plugging in. Thus, the necessary compensation, in particular when arranging the electric ventilator in a further housing, can be provided as well. The leaf spring contact element is a flexible contact element that can be flexibly deformed in response to the application of a force. This allows a reliable contact to be achieved.

[0017] Furthermore, it has proven to be advantageous if at least one of the shafts is formed substantially rectangular, so that the shaft can in particular act as a guide in the recess, which is likewise formed correspondingly substantially rectangular according to the shaft.

[0018] Furthermore, it can be ensured on the basis of the rectangular shape that, for example, an improper arrangement of the electric ventilator relative to a further housing is prevented. For example, it can be envisaged that a mistake-proofing element is additionally formed on the shaft and on the recess, whereby a reliable insertion of the shaft into the recess can be achieved.

[0019] In a further advantageous embodiment of the configuration, the housing comprises a ventilation outlet formed substantially perpendicular to the shaft. The ventilation outlet is in particular arranged facing the temperature control device. The generated air flow can thus be blown through the ventilation outlet, in particular by an electric ventilator, and can be guided towards the temperature control device. As a result, good cooling can be achieved by the temperature control device. The ventilation outlet is in particular formed perpendicular to the shaft. The ventilator can thus be arranged in a particularly flat manner in the further housing and can be in reliable contact with the further contact device to achieve good cooling.

[0020] According to a further advantageous embodiment of the configuration, the electric ventilator is configured as a radial fan. In other words, the electric ventilator comprises a type of air impeller which generates an air flow by moving about an axis of rotation. Due to this embodiment of the configuration, in particular a very simple and flat electric ventilator can be provided which can be put into contact with the electronic computer in a particularly simple manner. Due to this embodiment of the configuration, the electric ventilator can be made very compact, so that further space can be saved. The electric ventilator can thus be controlled in a simple manner, in particular since there are hardly any signals to be exchanged between the electronic computer and the electric ventilator. A reduction in the effort for the assembly of the electric ventilator into a further housing can thus be achieved.

[0021] A further aspect of the invention relates to an installation for an electronic computer, said installation comprising at least an electric ventilator according to the above-mentioned aspect and at least a further housing of the electronic computer, said electric ventilator fitting into a recess in the further housing with the shaft of said electric ventilator at least in a certain area. In particular, the electric ventilator and the temperature control device are formed on the outer surface of the further housing. In particular, the temperature control device can absorb thermal energy from the electronic computer and dissipate it to the surrounding environment of the electronic computer. Then, by means of the electric ventilator, the thermal energy can be dissipated in a good manner to the surrounding environment by means of the temperature control device on the basis of the air flow generated by the electric ventilator. A simple plug-in process of the electric ventilator into the further housing allows a simple assembly to be realized, which can for example be performed automatically without human intervention.

[0022] It is further advantageous if a sealing element for sealing the housing of the electric ventilator to the further housing of the computer is formed between the shaft and the recess. Thus, both the ventilator and the computer can be protected in particular from environmental influences. Thus, even with a simple assembly, protection from environmental influences can be reliably achieved. The sealing element is formed in a particularly flexible and rubber-like manner.

[0023] It has further proved to be advantageous if the housing of the electric ventilator is fixed to the outer surface of the further housing of the electronic computer by at least one screw element. In particular, the electric ventilator can be fixed, for example, to the electronic computer by at least two, in particular three, in particular four screw elements. The fixing can be performed automatically. This allows the entire installation and the fixing of the electric ventilator to the further housing to be performed automatically. The installation can thus be produced with almost no assembly effort. In particular, the fixing by screw elements, in particular by at least two screw elements, can ensure that the contact between the contact device of the electric ventilator and the contact device of the electronic computer is maintained after arrangement, in particular during driving operation of the motor vehicle in which the electronic computer is formed.

[0024] In a further advantageous form of configuration, the ventilation outlet of the electric ventilator faces the temperature control device, which is preferably equipped with a number of temperature control fins. Thus, the generated air flow can be blown onto the temperature control device through the ventilation outlet, in particular by the electric ventilator, so that the heat absorbed by the temperature control device can be reliably dissipated into the surrounding environment of the electronic computer. Thus, a good temperature control of the electronic computer can be realized.

[0025] A further aspect of the invention relates to an electronic computer comprising an arrangement according to the above aspect and at least a further circuit board in the interior space of said further housing.

[0026] In particular, the further circuit boards of the electronic computer comprise circuits, for example integrated circuits, as well as storage devices and processors, which generate heat during operation. By arrangement, this generated heat can be dissipated from the circuit boards and the internal space.

[0027] According to an advantageous embodiment of the electronic computer configuration, the contact device of the electric ventilator is directly contacted with a further contact device of the electronic computer, which is directly formed on the further circuit board of the electronic computer. In particular, the further contact device can, for example, be soldered directly to the further circuit board. The further contact device is thus fixed to the circuit board. The circuit board itself can, for example, be fixed in the further housing of the electronic computer. This allows the electrical contact between the electric ventilator and the further contact device to be realized by simply inserting a shaft into a recess. In this way, weight and installation space can be saved, since it is not necessary to form a connection by a cable between the circuit board and the further contact device, for example. The circuit board therefore also forms a stop for the further contact device and thus for the contact device and in particular for the electric ventilator in contact with the contact device.

[0028] The advantageous forms of configuration of the electric ventilator are to be regarded as advantageous forms of configuration of the installation and the electronic computer.

The assistance system 2 can be, for example, a parking assistance system, a lane departure warning system, etc. Thus, at least partially autonomous driving of the motor vehicle 1 can be provided, in particular by the assistance system 2. The assistance system 2 comprises at least one electronic computer 3. The electronic computer 3 can capture and process information, for example from a capture device 5 for capturing the surrounding environment 4 of the assistance system 2, and can perform a corresponding evaluation. The electronic computer 3 can in particular comprise a further circuit board 6 (Fig. 2), on which are formed, for example, integrated circuits and / or processors that are formed for performing corresponding evaluation and assessment steps for the assistance system 2. Furthermore, the capture device 5 can be in contact with the electronic computer 3, for example via a corresponding cable connection 6.

[0033] Fig. 2 shows a schematic perspective view of an embodiment of an electronic calculator 3 with an embodiment of an electric ventilator 7. The electronic calculator 3 comprises, inter alia, a further circuit board 6 in an interior space 8 of the electronic calculator 3. The electronic calculator 3 is surrounded by a further housing 9. The electric ventilator 7 comprises a housing 10. A radial fan 12 is shown in the housing 10, in particular in the interior space 11 of the housing 10. The radial fan 12 comprises, inter alia, corresponding fins which generate an air flow 13 (Fig. 3) which generates the heat generated by the electronic calculator 3 in order to dissipate it into the surrounding environment.

[0034] The electric ventilator 7 is equipped with a contact device 14. The electronic computer 3 is equipped with a further contact device 15.

[0035] In particular, the electric ventilator 7 is formed for a temperature control device 16 (FIG. 3) of the electronic calculator 3. The electric ventilator 7 comprises a housing 10 in which an electric ventilation device 17 of the electric ventilator 7 is arranged. The electric ventilator 7 then comprises a contact device 14 which is formed for contacting a further contact device 15 of the electronic calculator 3. The contact device 14 is formed for transmitting at least electrical energy from the electronic calculator 3 to the electric ventilation device 17.

[0036] The housing 10 in particular comprises a shaft 18 which is designed in a certain area to fit into a recess 19 corresponding to the shaft 18 in the further housing 9 of the electronic calculator 3. The contact device 14 is fixed in the shaft 18 and is designed to be in direct wireless contact with the further contact device 15.

[0037] In particular, FIG. 2 shows that the electric ventilation device 17 may comprise a first circuit board 33 on which at least one electrical component for the electric ventilation device 17 is formed. For example, corresponding control elements, processors and integrated circuits for the electric ventilation device 17, for example for the rotation speed control of the radial fan 12, may be formed on the first circuit board 33. The contact device 14 comprises in particular a second circuit board 20 which is fixed in the shaft 18. In particular, the second circuit board 20 may be glued or screwed to the shaft, for example. Furthermore, the second circuit board 20 may be injection molded on the shaft 18. The contact device 14 faces in particular against the upper side of the second circuit board 20, in particular facing the upper side of the further circuit board 6. The lower side of the second circuit board 20 may face the first circuit board 33.

[0038] As shown in Fig. 2, the electrical contact between the contact device 14 and the further contact device 15 is effected directly by plugging the shaft 18 into the recess 19. This means that, for example, an installer does not have to effect the connection manually. Thus, manual operations or manual plug-in connections required for effecting the electrical connection between the electric ventilator 7 and the electronic computer 3 can in particular be omitted. It can thus be envisaged that, for example, an automatic assembly process of the electronic ventilator 7 to the electronic computer 3 can be effected.

[0039] 2 further shows that at least the shaft 18 is formed substantially rectangular. In particular, the recess 19 is also formed rectangular. This prevents, for example, an incorrect positioning of the electric ventilator 7 on the electronic computer 3, in particular on the further housing 9. It can in particular further be envisaged that error-proofing elements are formed, for example, on both the shaft 18 and on the recess 19. This ensures a reliable and correct plugging-in of the electric ventilator 7 into the further housing 9.

[0040] 3 shows a schematic perspective view of an electronic calculator 3. The electronic calculator 3 is in particular equipped with a number of cable connections 6 by means of which the electronic calculator 3 can, for example, be contacted with a capture device 5. Furthermore, the electronic calculator 3 can, for example, also be connected via the cable connections 6 to a bus system of the motor vehicle 1.

[0041] FIG. 3 further shows an embodiment of the arrangement 21. The arrangement 21 is in particular designed for an electronic calculator 3 and comprises at least an electric ventilator 7 as well as a temperature control device 16. Furthermore, the arrangement 3 comprises at least a further housing 9. The electric ventilator 7 fits into a recess 19 on the shaft 18. In particular, it is shown that the housing 10 of the electric ventilator 7 is fixed to the further housing 9 of the electronic calculator 3 by at least one screw element 23, in particular by two screw elements 23. Furthermore, FIG. 3 shows that a ventilation outlet 24 of the electric ventilator 7 faces the temperature control device 16 and can in particular generate an air flow 19. In particular, as shown, the electric ventilator 7 is designed as a radial fan 12. As shown in FIG. 3, air 25 can be sucked in and can pass as an air flow 13 through the temperature control device 16, which in particular comprises a number of temperature control fins.

[0042] FIG. 4 shows a perspective top view of the underside 26 of the electric ventilator 7. In particular, FIG. 4 shows a view of the underside 26 of the housing 10 of the electric ventilator 7. An axis A is particularly shown, about which the impeller of the radial fan 12 of the electric ventilator 7 is rotatable. Furthermore, FIG. 4 shows the shaft 18 as well as the second circuit board 20, which is fixed to the shaft 18 via a further screw element 27. The contact device 14 comprises at least two contact elements 28, in particular four contact elements 28. In particular, it can be envisaged that the further contact device 15 likewise comprises at least two contact elements 28, in particular four contact elements 28. A direct contact between the first contact device 14 and the second contact device 15 can be realised via the contact elements 28.

[0044] FIG. 6 shows a schematic cross-sectional view of an embodiment of the electric ventilator 7, which is arranged in particular in the shaft 18 in a recess 19. In particular, the shaft 18 fits into the recess 19. The first contact device 14 is in contact with the second contact device 15. The second circuit board 20 can be connected in a wired manner, in particular to the first circuit board 19, which is not shown here, via a further cable connection 30. In particular, the further cable connection 30 is a flexible further cable connection 30. The further cable connection 30 comprises in particular four individual wires, of which two are formed for the electrical energy transmission and two for the control signal transmission. In this embodiment, in particular, it is shown that the housing 10 of the electric ventilator 7 is sealed to the outer surface 22 of the further housing 9 of the electronic computer 3 by at least one sealing element 31. Thus, the sealing element 31 for sealing the housing 10 of the electric ventilator 7 to the further housing 6 of the electronic computer 3 is formed in particular between the shaft 18 and the recess 19. Thus, both, in particular, the electric ventilator 7 and the electronic computer 3 can be protected from the influences of the surrounding environment.

[0045] FIG. 7 shows a further schematic cross-sectional view of an embodiment of an electric ventilator 7 on an electronic calculator 3. It is shown in particular that the electric ventilator 7 is arranged in a recess 19 in the shaft 18 and is in direct contact with the further contact device 15, in particular via a contact device 14. It is shown in particular that the contact device 14 comprises at least two contact elements 28. The contact elements 28 of the further contact device 15 are in particular formed as leaf spring contact elements 32. This allows a reliable contact between the first contact device 14 and the second contact device 15 to be realized. In particular, the contact elements 28 of the contact device 14 can be formed as contact elements 28 corresponding to the leaf spring contact elements 32. On the basis of the leaf spring contact elements 32, it is in particular possible that a contact between the contact device 14 and the further contact device 15 can be reliably realized when plugging in. Thus, compensations, which are necessary in particular when arranging the electric ventilator 7 in the further housing 9, can also be provided. The leaf spring contact elements 32 are flexible contact elements 28, which can be correspondingly flexibly deformed in particular when a force is applied. This allows for reliable contact.

[0046] It is shown in particular that four further cable connections 30 are formed. In particular, the first contact device 14 and the second contact device 15 are also provided with four contact elements 28. Electrical energy can therefore in particular be transmitted, for example, via two of the contact elements 28. It can then be envisaged that a control signal can be transmitted from the electronic computer 3 to the electric ventilator 7 via the two further contact elements 28. In particular, a control signal can be transmitted to the electric ventilator 17.
