Description

Technical Field

[0001] This invention relates to an electric fan for a temperature control device of an electronic computing device, having a housing in which an electric ventilation device is disposed, and having an electrical contact device configured to contact another electrical contact device of the electronic computing device, wherein the contact device is configured to transfer electrical energy from the electronic computing device to the electric ventilation device. Furthermore, this invention relates to a device for an electronic computing device and an electronic computing device itself. Background Technology

[0002] In the prior art, electric fans are known to be incorporated as part of a temperature control system for electronic computing devices. Specifically, during the corresponding computational operations of the electronic computing device, heat energy, particularly hot energy, is generated, which must be dissipated by a corresponding temperature control device to enable higher power output from the electronic computing device. Thus, for example, it can be proposed that the temperature control device includes corresponding cooling fins that absorb heat energy and then dissipate it into the environment of the electronic computing device. To achieve improved cooling through the temperature control device, an electric fan can be arranged to blow air over the cooling fins, thereby improving heat dissipation from the cooling fins to the environment. Therefore, more efficient cooling of the electronic computing device can be achieved. Summary of the Invention

[0003] The purpose of this invention is to provide electric ventilators, equipment, and electronic computing devices by means of which labor-saving assembly can be achieved.

[0004] This objective is achieved by the electric ventilator, apparatus, and electronic computing device according to the independent claims. Advantageous configurations are proposed in the dependent claims.

[0005] One aspect of the present invention provides an electric fan for a temperature control device of an electronic computing device, having a housing and an electric contact device in which the electric fan is arranged, the electric contact device being configured to contact another electric contact device of the electronic computing device, wherein the contact device is configured to at least transfer electrical energy from the electronic computing device to the electric fan.

[0006] A housing is proposed that includes a shaft formed for insertion into a corresponding recess on another housing of an electronic computing device in a specific region, wherein a contact device is fixed in the shaft and formed for wireless and direct contact with another contact device.

[0007] Therefore, the assembly of the electric fan to another housing of the electronic computing device can be achieved with particularly little effort. Thus, it is particularly possible to achieve direct contact between the electric fan and the other housing when attaching the electric fan to the other housing. Therefore, through direct contact, for example, manual plug connections for contact between the electric fan and the electronic computing device do not need to be plugged in, thereby enabling, for example, an automated assembly process of the electric fan to the other housing.

[0008] In other words, it is proposed that when attaching an electric ventilator, the shaft is inserted into the recess and is already in direct contact with another contact device during or at least after the insertion process. Therefore, it is unnecessary to perform an additional, particularly manual, connection or insertion process on the other contact device. Contact is achieved during the insertion process by inserting the shaft into the recess and fixing the contact device.

[0009] Specifically, the shaft is a hollow cylinder, and the contact device is fixed within the hollow shaft. In other words, the contact device is formed within the internal space of the shaft. Furthermore, the contact device is fixed, for example, to the inside of the shaft with screws.

[0010] For example, the temperature control device can be provided by multiple, particularly more than one, cooling fins or cooling brackets. Specifically, an electric fan is allowed to blow air toward the temperature control device, thus generating an airflow that allows the air to absorb heat from the temperature control device, thereby ensuring improved cooling of the electronic computing device. For example, improved computing power of the electronic computing device can be achieved through improved cooling.

[0011] The contact device can be fixed to the shaft, for example, by screws. Alternatively, the contact device can be fixed to the shaft by appropriate adhesive bonding or clamping devices. The contact device can also be injection molded onto the shaft.

[0012] Preferably, the temperature control device is configured to cool the electronic computing device. However, it may also be proposed that heating of the electronic computing device be achieved through the temperature control device.

[0013] According to a further advantageous configuration, the electric ventilation device includes a first circuit board on which at least one electrical component for the electric ventilation device is formed, and a contact device includes a second circuit board fixed to the shaft. Thus, the contact device is particularly formed on a circuit board, which may also be referred to as a printed circuit board (PCB). For example, corresponding contact elements for contact can be formed on the second circuit board. The second circuit board is particularly fixed in the hollow shaft. Furthermore, the ventilation device includes the first circuit board, which may, for example, include corresponding circuitry for controlling the electric ventilation device. In particular, the first circuit board is formed in the internal space of the housing, and the second circuit board is formed in the internal space of the shaft on the housing.

[0014] Furthermore, it has proven advantageous that the first and second circuit boards are fixed to each other by wires. Therefore, any potential movement between the first and second circuit boards can be compensated for, in particular, by the wired connection. The wired connection is especially a flexible wired connection. For example, if an electronic computing device is incorporated into a motor vehicle, shocks during the vehicle's driving operation can be reliably absorbed.

[0015] A further advantage is that the contact device is configured to transmit control signals from the electronic computing device to the electric ventilation device in addition to transmitting electrical energy. For example, speed control, such as rotational speed, for the electric ventilation device can be transmitted to the electric ventilation device as a control signal. Therefore, the control of the electric ventilation device can be achieved, in particular, through the electronic computing device. Thus, by inserting the electric ventilation fan, contact for energy transmission and for control signal transmission can be directly performed. Therefore, the rotational speed of the electric ventilation device can be adapted, for example, to the computing power of the electronic computing device and the heat generated by the electronic computing device. Therefore, reliable operation of the electronic computing device can still be achieved effortlessly by assembling the electric ventilation fan onto another housing.

[0016] In another advantageous configuration, the contact device includes at least two contact elements, particularly at least four contact elements, and another contact device includes at least two, particularly four, contact elements corresponding to the contact elements. For example, the two contact elements can be configured for transmitting electrical energy. Thus, the first contact element can, for example, represent a positive electrode, and the second contact element can represent a negative electrode. In the configuration with four contact elements, it can be specifically specified that at least a third and fourth contact element are used for transmitting control signals. Therefore, based on the direct contact between the contact elements, both energy and control signals can be reliably transmitted. As a result, assembly work can be greatly reduced, because in particular, it is no longer necessary to manually arrange the electric ventilator on another housing and correspondingly manually contact it to transmit electrical energy and control signals from the electronic computing device to the electric ventilator.

[0017] Furthermore, it has proven advantageous that at least one of the contact elements of the contacting device or the other contacting device is formed as a leaf spring contact element. In particular, the contact element of the other contacting device can be formed as a contact element corresponding to the leaf spring contact element. Based on the leaf spring contact element, reliable contact between the contacting device and the other contacting device can be reliably achieved upon insertion. Therefore, compensation can also be provided, which is necessary when the electric ventilator is arranged on another housing. The leaf spring contact element is particularly a flexible contact element, which can flexibly deform accordingly when force is applied, thereby enabling reliable contact.

[0018] Furthermore, it has proven advantageous that the shaft is at least substantially rectangular in shape. Therefore, the shaft can be specifically used as a guide within the recess. Correspondingly, the recess is also substantially rectangular in shape. Moreover, based on the rectangular shape, for example, it is possible to ensure the prevention of incorrect placement of the electric fan on another housing. Thus, for example, it is possible to specify additional anti-misalignment elements formed on the shaft and the recess, thereby enabling reliable insertion of the shaft into the recess.

[0019] In another advantageous configuration, the housing includes a ventilation outlet formed substantially perpendicular to the axis. The ventilation outlet is specifically positioned such that it faces the temperature control device. Therefore, the resulting airflow can be blown across the ventilation outlet by an electric fan and directed to the temperature control device, thereby achieving improved cooling. The ventilation outlet is particularly formed perpendicular to the axis. Therefore, the fan can be arranged flat on another housing and still reliably contact another contact device, achieving improved cooling.

[0020] According to a further advantageous configuration, the electric ventilation device is formed as a radial-flow fan. In other words, the electric ventilation device includes an air impeller that moves about an axis of rotation, thereby generating airflow. This configuration allows for a particularly simple and flat electric fan, which can be easily integrated with the electronic computing device. This configuration further saves installation space because the electric fan is formed very compactly. Therefore, very few signals must be exchanged between the electronic computing device and the electric fan, allowing for simplified control of the electric ventilation device. Thus, the electric fan can be easily assembled onto another housing.

[0021] Another aspect of the invention relates to a device for an electronic computing device, having at least one electric fan according to the foregoing aspect, and having at least another housing of the electronic computing device, wherein the electric fan is inserted into a recess in the other housing via its shaft, at least in a specific area. Specifically, the electric fan and a temperature control device are formed on the outside of the other housing. Specifically, the temperature control device can then absorb heat energy from the electronic computing device and dissipate it into the environment of the electronic computing device. With the aid of the electric fan, heat energy can then be dissipated into the environment in an improved manner by means of the airflow generated by the electric fan through the temperature control device. Simple assembly can be achieved through the simple insertion process of the electric fan into the other housing, which can, for example, be performed automatically without human intervention.

[0022] A further advantage is that the sealing element for the housing of the electric ventilator, which is another housing for sealing the electronic computing device, is formed between the shaft and the recess. Therefore, both the ventilator and the electronic computing device can be protected from environmental influences. Thus, protection from environmental influences can still be reliably achieved with simple components. The sealing element is particularly flexible and rubber-like.

[0023] It has further proven advantageous that the housing of the electric ventilator is secured to the outside of another housing of the electronic computing device by at least one screw element. Specifically, the electric ventilator can be secured to the electronic computing device, for example, by at least two, particularly three, particularly four screw elements. This securing can also be done automatically, allowing for the automated arrangement and securing of the electric ventilator to the other housing. Therefore, the device can be manufactured with less assembly work. In particular, by means of screw elements, especially by means of at least two screw elements, contact between the contact device of the electric ventilator and the electronic computing device can be reliably maintained, ensuring that electrical contact between the contact devices is maintained after arrangement, particularly in the driving operation of, for example, a motor vehicle in which the electronic computing device is formed.

[0024] In a further advantageous configuration, the ventilation outlet of the electric fan faces the temperature control device. Therefore, the generated airflow can be directed by the electric fan towards the temperature control device via the ventilation outlet, thereby reliably dissipating the heat absorbed by the temperature control device into the environment of the electronic computing device. Thus, improved temperature control of the electronic computing device can be achieved.

[0025] Another aspect of the present invention relates to an electronic computing device having at least the device according to the foregoing aspects, and having at least another circuit board in the interior space of another housing.

[0026] Specifically, another circuit board in the electronic computing device includes circuitry that generates heat during operation, such as integrated circuits, as well as storage devices and a processor. This arrangement allows the generated heat to dissipate from the circuit board and the internal space.

[0027] According to an advantageous configuration of the electronic computing device, the contact device of the electric ventilator is in direct contact with another contact device of the electronic computing device, which is directly formed on the circuit board of the electronic computing device. Specifically, the other contact device can be directly soldered to another circuit board, for example. Thus, the other contact device is fixed to the circuit board. The circuit board itself can, for example, be fixed within another housing of the electronic computing device. Therefore, electrical contact between the electric ventilator and the other contact device can be achieved simply by inserting a shaft into a recess. This saves weight and installation space, as, for example, it is not necessary to form a cable connection between the circuit board and the other contact device. Therefore, the circuit board also forms a stop for the other contact device, and thus also forms a stop for the contact device, and thus also forms a stop for the electric ventilator, especially in the state of contact with the contact device.

[0028] The preferred configuration of the electric ventilator is considered to be the preferred configuration of the equipment and the electronic computing device.

[0030] The invention will now be explained in more detail based on preferred embodiments and with reference to the accompanying drawings. Attached Figure Description

[0040] Figure 1 A schematic top view of an embodiment of a motor vehicle 1 is shown. Specifically, the motor vehicle 1 includes an assistance system 2. The assistance system 2 may be, for example, a parking assistance system, a lane departure warning system, etc. Therefore, at least partial autonomous operation of the motor vehicle 1 can be provided, in particular, by the assistance system 2. The assistance system 2 further includes at least one electronic computing device 3. The electronic computing device 3 can, for example, capture and process information from a capture device 5 to capture the environment 4 of the assistance system 2 and perform corresponding assessments. Hereinafter, the electronic computing device 3 may particularly include another circuit board 6 (… Figure 2 On this other circuit board, for example, integrated circuits and processors are formed to perform the corresponding evaluation and assessment steps of the auxiliary system 2. Furthermore, the capture device 5 can be connected, for example, via a corresponding cable to 6 (…). Figure 1 It comes into contact with the electronic computing device 3.

[0041] Figure 2 A schematic perspective view of an embodiment of an electronic computing device 3 having an electric fan 7 is shown. The electronic computing device 3 specifically includes another circuit board 6 within its internal space 8. The electronic computing device 3 is surrounded by another housing 9. The electric fan 7, in turn, includes a housing 10. Currently, a radial fan 12 is shown in the housing 10, particularly within its internal space 11. It specifically includes corresponding fins to generate an airflow 13. Figure 3 The airflow 13 is generated to dissipate the heat generated by the electronic computing device 3 into the environment 4.

[0042] The electric ventilator 7 includes a contact device 14. The electronic computing device 3 includes another contact device 15.

[0043] Specifically, the electric ventilator 7 is configured as a temperature control device 16 for the electronic computing device 3. Figure 3Thus, the electric ventilator 7 includes a housing 10, an electric ventilation device 17 of the electric ventilator 7 is arranged in the housing 10, and the electric ventilator 7 includes a contact device 14 configured to contact another contact device 15 of the electronic computing device 3. The contact device 14 is configured to at least transfer electrical energy from the electronic computing device 3 to the electric ventilation device 17.

[0044] Thus, housing 10 specifically includes shaft 18, which is formed for insertion into a corresponding recess 19 on another housing 9 of electronic computing device 3 in a specific area, wherein contact device 14 is fixed in shaft 18 and formed for wireless and direct contact with another contact device 15.

[0045] In particular, Figure 2 The electrically ventilated device 17 is shown to include a first circuit board 33 on which at least one electrical component for the electrically ventilated device 17 is formed. For example, corresponding control elements, processors, and integrated circuits for the electrically ventilated device 17 can be formed on the first circuit board 33, such as for speed control of the radial fan 12. The contact device 14 specifically includes a second circuit board 20 fixed in the shaft 18. In particular, the second circuit board 20 can be, for example, adhered or screwed onto the shaft. Furthermore, the second circuit board 20 can also be injection molded onto the shaft 18. The contact device 14 is particularly opposed to the top side of the second circuit board 20 and particularly faces the top side of another circuit board 6. The bottom side of the second circuit board 20 can face the first circuit board 33.

[0046] like Figure 2 As shown, the electrical contact between contact device 14 and another contact device 15 is made directly by inserting shaft 18 into recess 19, eliminating the need for manual connection by, for example, an assembler. Therefore, the insertion connection, which must be performed manually or by hand, between the electric fan 7 and the electronic computing device 3, is particularly omitted. Thus, for example, an automated assembly process from the electric fan 7 to the electronic computing device 3 can be provided.

[0047] Figure 2 It is also shown that at least shaft 18 is formed substantially in a rectangular shape. In particular, recess 19 is also formed in a rectangular shape. Therefore, it is possible to prevent, for example, the electric fan 7 from being incorrectly arranged on the electronic computing device 3, especially on the other housing 9. Furthermore, it can be specifically further specified that anti-misinsertion elements are formed, for example, on shaft 18 and recess 19, thereby ensuring reliable and correct insertion of the electric fan 7 into the other housing 9.

[0048] Figure 3A schematic perspective view of the electronic computing device 3 is shown. Currently, the electronic computing device 3 specifically includes multiple cable connections 6, through which the electronic computing device 3 can, for example, contact the capture device 5. Furthermore, the electronic computing device 3 can also, for example, be connected to the bus system of the motor vehicle 1 via the cable connections 6.

[0049] Figure 3 An embodiment of device 21 is further illustrated. Device 21 is specifically configured for electronic computing device 3 and includes at least an electric fan 7 and a temperature control device 16. Furthermore, device 3 includes at least another housing 9. Currently, the electric fan 7 is inserted into a recess 19 along with a shaft 18. Specifically, the housing 10 of the electric fan 7 is shown to be secured to the outside 22 of the other housing 9 of electronic computing device 3 by at least one screw element 23 (currently, specifically two screw elements 23). Furthermore, Figure 3 The ventilation outlet 24 of the electric ventilator 7 is shown facing the temperature control device 16, and is particularly capable of generating an airflow 13. Specifically, as shown here, the electric ventilator 7 is configured as a radial flow fan 12. Thus, as... Figure 3 As shown, air 25 can be drawn in and then flow as airflow 13 through temperature control device 16, which currently specifically includes multiple temperature control fins.

[0050] Figure 4 A schematic perspective top view of the bottom side 26 of the electric ventilator 7 is shown. Specifically, Figure 4 A view of the bottom side 26 of the housing 10 of the electric ventilator 7 is shown. Currently, axis A is shown in particular, about which the impeller of the radial fan 12 of the electric ventilator 7 can rotate. Furthermore, Figure 4 Shaft 18 and a second circuit board 20 are shown, which is currently secured to shaft 18 by additional screw elements 27. Contact device 14 currently includes at least two contact elements 28, particularly four contact elements 28. Specifically, it can then be specified that another contact device 15 also includes at least two contact elements 28, particularly four contact elements 28. Direct contact between the first contact device 14 and the second contact device 15 can be achieved through the contact elements 28.

[0051] Figure 5 Another schematic top view of an embodiment of the electric ventilator 7 is shown, particularly the top side 29 of the electric ventilator 7 and the housing 10. In particular, the ventilation outlet 24 is further shown.

[0052] Figure 6A schematic cross-sectional view of an embodiment of an electric ventilator 7 is shown, which is arranged in a recess 19, particularly via a shaft 18. Specifically, the shaft 18 is currently inserted into the recess 19. A first contact device 14 contacts a second contact device 15. A second circuit board 20 can be wired to a first circuit board (not shown) via another cable connection 30. Specifically, the other cable connection 30 is a flexible cable connection 30. Currently, the other cable connection 30 includes four separate wires, two of which can be configured for power transmission and two for control signal transmission. In this embodiment, the housing 10 of the electric ventilator 7 is specifically shown sealed to the outside 22 of another housing 9 of the electronic computing device 3 by at least one sealing element 31. Therefore, the sealing element 31 for sealing the housing 10 of the electric ventilator 7 relative to the other housing 6 of the electronic computing device 3 is formed particularly between the shaft 18 and the recess 19. Therefore, the electric ventilator 7 and the electronic computing device 3 are particularly protected from environmental influences.

[0053] Figure 7 Another schematic cross-sectional view of an embodiment of an electric fan 7 on an electronic computing device 3 is shown. Specifically, the electric fan 7 is shown arranged in a recess 19 via a shaft 18 and is in direct contact with another contact device 15 via a contact device 14. The contact device 14 is shown to include at least two contact elements 28. The contact element 28 of the other contact device 15 is particularly formed as a leaf spring contact element 32, enabling reliable contact between the first contact device 14 and the second contact device 15. Specifically, the contact element 28 of the contact device 14 can then be formed as a contact element 28 corresponding to the leaf spring contact element 32. Based on the leaf spring contact element 32, reliable contact between the contact device 14 and the other contact device 15 is particularly allowed upon insertion. Therefore, compensation can also be provided, which is necessary when arranging the electric fan 7 on another housing 9. The leaf spring contact element 32 is, in particular, a flexible contact element 28, which can be flexibly deformed accordingly when force is applied, thereby enabling reliable contact.

[0054] Specifically, four additional cable connections 30 are currently shown. In particular, the first contact device 14 and the second contact device 15 now also include four contact elements 28. Therefore, electrical energy can be transmitted, for example, via two of the contact elements 28, and control signals can be transmitted from the electronic computing device 3 to the electric ventilator 7 via the other two contact elements 28. Specifically, control signals can be transmitted to the electric ventilation device 17.
