Description

Technical Field

[0001] This utility model belongs to the field of controller technology and relates to an intelligent cockpit air-cooled heat dissipation controller. Background Technology

[0002] With the development of intelligent and human-centered automobiles, intelligent cockpit systems have become widespread. These systems include central control screens, instrument panels, and in-vehicle infotainment systems. Some also involve processing units related to advanced driver assistance systems (ADAS). These devices have high requirements for heat dissipation because the ambient temperature inside the vehicle varies greatly, and the controllers may run for extended periods and perform complex tasks, generating a lot of heat. Therefore, an effective heat dissipation structure is needed to ensure the stable operation of the controllers.

[0003] Common heat dissipation methods include thermal grease, heat sinks, and heat pipes, but these are no longer sufficient to meet the heat dissipation requirements of such controllers. There are also cooling methods using liquid cooling systems, which transfer heat from the heat source chip surface to the external environment through flowing coolant. The core principle is to utilize the high heat capacity and thermal conductivity of liquids to manage heat more efficiently than traditional air cooling, but this method is costly and requires a large installation space. Some even use low-power chips to reduce the heat generated, but currently, low-power chips still cannot meet the intelligent application requirements of smart cockpit systems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides an intelligent cockpit air-cooled heat dissipation controller, including a hood, a base plate, a main control board, an auxiliary board, an antenna, a cover plate, and an axial fan. The hood has a base plate at its bottom, a main control board on the base plate, an auxiliary board above the main control board, a recessed mounting groove on the hood, an antenna within the recessed mounting groove, a cover plate located at the recessed mounting groove, an exhaust mounting position on the inner side of the hood, an axial fan within the exhaust mounting position, several air inlets on the side of the hood, and several strip-shaped air ducts inside the hood. The left and right sides of the strip-shaped air ducts correspond to the air inlets and the axial fan, respectively, to form airflow convection. The main control board is electrically connected to the auxiliary board, the antenna, and the axial fan.

[0006] Preferably, the main control board is provided with a main chip, which is located directly below the strip-shaped air duct.

[0007] Preferably, the auxiliary board is provided with a plurality of auxiliary chips, which are positioned away from the main chip.

[0008] Preferably, the outer side of the top of the cover is provided with several saw-shaped heat dissipation ribs.

[0012] Preferably, the cover, bottom plate, and cover plate are all made of aluminum profiles.

[0013] The advantages of this utility model over the prior art are:

[0014] This utility model provides an intelligent cockpit air-cooled heat dissipation controller.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0022] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] To achieve the above objectives, this utility model provides an intelligent cockpit air-cooled heat dissipation controller, as shown in the reference. Figure 1-3 As shown, the device includes a cover 1, a base plate 2, a main control board 3, an auxiliary board 4, an antenna 5, a cover plate 6, and an axial fan 7. The base plate 2 is located at the bottom of the cover 1, the main control board 3 is located on the base plate 2, and the auxiliary board 4 is located above the main control board 3. The cover 1 has a recessed mounting groove 8, and the antenna 5 is located in the recessed mounting groove 8. The cover plate 6 is located at the position of the recessed mounting groove 8. The exhaust mounting position 9 is located on the inner side of the cover 1, and the axial fan 7 is located in the exhaust mounting position 9. The side of the cover 1 has several air inlets 10, and the inside of the cover 1 has several strip-shaped air ducts 11. The left and right sides of the strip-shaped air ducts 11 correspond to the air inlets 10 and the axial fan 7 respectively to form air duct convection. The main control board 3 is electrically connected to the auxiliary board 4, the antenna 5, and the axial fan 7. The side of the cover 1 has several air outlets 15 for the axial fan 7 to exhaust heat.

[0024] Furthermore, the main control board 3 is equipped with a main chip 12, which is located directly below the strip-shaped air duct 11. The auxiliary board 4 is equipped with several auxiliary chips 13, which are set away from the main chip 12. The main control board 3 and the auxiliary board 4 are set up vertically, with a certain amount of space to facilitate vertical heat dissipation and airflow.

[0025] Furthermore, the rear end of the cover 1 is provided with an opening 16, and an assembly panel 17 is installed at the opening 16 position, so that the wiring terminals on the main control board 3 and the auxiliary board 4 can be fitted into the assembly panel 17. Mounting brackets 18 are provided on both the left and right sides of the cover 1 to facilitate the installation and fixation of the controller.

[0026] In this embodiment, the controller generates heat during use, especially during long-term use in the field of intelligent cockpit systems and in dealing with complex data control. The operation of the main control board 3 and the auxiliary board 4 will generate more heat. The current conventional thermal grease, heat sink, and heat pipe can no longer meet the heat dissipation requirements, while liquid cooling is costly and requires a large structural volume, which does not meet the enterprise's cost control and controller heat dissipation improvement and upgrade. Therefore, this embodiment creatively improves the structure of the controller to meet the increasing demand for intelligent cockpit system controllers.

[0027] Specifically, the use of aluminum profiles for the cover 1, base plate 2, and cover plate 6 facilitates heat dissipation. Several saw-shaped heat dissipation ribs 14 are provided on the top outer side of the cover 1, increasing the heat dissipation area and the contact area of ​​heat inside the cover 1, which helps to dissipate heat better. Furthermore, the strip-shaped air duct 11 is arranged in a straight line with the air inlet 10 and the axial fan 7. External air can enter the strip-shaped air duct 11 from the air inlet 10 and the heat is drawn out to the outside of the cover 1 by the axial fan 7 at the rear end, forming a straight air duct convection to achieve rapid heat dissipation. Moreover, the main chip 12 is the main chip that generates heat. The improved design places it directly below the strip-shaped air duct 11, so that heat can be quickly and effectively discharged by convection. The auxiliary chip 13 is placed away from the main chip 12 to help disperse the heat inside the cover 1 and prevent it from being too concentrated, which would lead to poor heat dissipation. This better protects the controller and improves the heat dissipation capacity. Of course, the heat generated by the auxiliary chip 13 is discharged through the airflow of the strip-shaped air duct 11 in the space of the cover 1. The heat generated by the auxiliary chip 13 will automatically be replenished to the position of the strip-shaped air duct 11, so as to better achieve the heat dissipation of the whole machine. The heat dissipation is better, the cost is lower, which meets the cost control of enterprises and the product also meets the market demand, and has high practicality.

[0028] In summary, this utility model provides an intelligent cockpit air-cooled heat dissipation controller. By designing saw-shaped heat dissipation ribs 14 on the aluminum profile cover 1, the heat dissipation surface can be increased. The strip-shaped air duct grooves 11 set in the cover 1 correspond to the air inlet 10 and the axial fan 7 respectively, so that the air in the air duct is straight convection. An axial fan 7 is installed at one end, and an air inlet 10 is designed at the convection position of the other end. The axial fan 7 draws out the hot air in time, improving the air convection efficiency. Moreover, the main chip 12 is arranged at the convection position of the air duct, which can increase the heat dissipation and effectively improve heat dissipation. The spatial structure layout is reasonable, the cost is low, and it meets the heat dissipation requirements of the controller.

[0029] The technical principles of this utility model have been described above with reference to specific embodiments, which are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments; all technical solutions falling within the scope of this utility model's concept are protected. Those skilled in the art can conceive of other specific embodiments of this utility model without creative effort, and these will also fall within the protection scope of this utility model.
