Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of controller technology, specifically to an autonomous vehicle domain controller. Background Technology
[0002] As the central computing hub of the entire vehicle, the domain controller of an autonomous vehicle needs to process data from multiple sensors such as cameras and LiDAR in real time, with a typical power consumption of 80-150W.
[0003] Currently, existing solutions generally adopt a box-type package structure for automotive domain controllers. However, the heat dissipation design of traditional automotive domain controllers is inadequate, and heat accumulation inevitably occurs after prolonged operation. The control circuit board, installed inside the box, experiences temperature increases after continuous operation, and the lack of effective heat dissipation easily leads to problems with the electronic components on the control circuit board. Therefore, it is necessary to propose an improvement measure to solve the above-mentioned technical problems.
[0004] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content
[0005] 1. The technical problem to be solved by the utility model: This utility model provides an autonomous vehicle domain controller to solve the technical problems existing in the background art.
[0006] 2. Technical Solution: To achieve the above objectives, the technical solution provided by this utility model is as follows: an autonomous vehicle domain controller, comprising a base plate, a cover plate, and a control circuit board, wherein the cover plate is correspondingly mounted on the base plate, and the control circuit board is correspondingly mounted inside the cover plate; a wind chamber is correspondingly provided on the inner side of the top of the cover plate, and a plurality of air outlet holes pointing to the top of the control circuit board are evenly opened on the partition plate at the bottom of the wind chamber, and a plurality of guide plates are correspondingly provided at the bottom of the partition plate, the guide plates being inclined and pointing to the rear; a heat dissipation cavity is also formed between the control circuit board and the base plate, and an inverted U-shaped heat dissipation plate is correspondingly installed in the heat dissipation cavity, the top of the heat dissipation plate being attached to the bottom of the control circuit board, and a plurality of cross-shaped heat dissipation fins being spaced apart at the bottom of the heat dissipation plate; a centralized air cavity for supplying cold air is correspondingly provided inside the front side of the cover plate, and the wind chamber and the heat dissipation cavity are both connected to the centralized air cavity; a plurality of heat dissipation holes are spaced apart on the rear side of the cover plate, and the heat dissipation holes are all connected to the wind chamber and the heat dissipation cavity.
[0007] Furthermore, the centralized air cavity and the air chamber are connected by a row of first air supply holes; the centralized air cavity and the heat dissipation cavity are connected by a row of second air supply holes.
[0008] Furthermore, the bottom plate has corresponding blocks at the top four positions, the bottom of the control circuit board is mounted on the blocks, and a heat dissipation cavity is formed around the bottom of the control circuit board, the top of the bottom plate, and the cover plate.
[0009] Furthermore, a connection port is provided in the middle of the outer wall of the centralized air cavity for connecting to an external cooling device.
[0010] Furthermore, the bottom of the partition is provided with multiple sets of horizontally spaced guide plates, and each set of guide plates is vertically spaced.
[0011] Furthermore, a certain gap is left between the bottom of the guide plate and the top of the electrical components on the control circuit board.
[0012] 3. Beneficial effects: Compared with the prior art, the technical solution provided by this utility model has the following advantages: This utility model features a reasonable design. By incorporating a wind chamber and air outlet within the cover plate at the top of the control circuit board, along with multiple guide plates angled towards the rear heat dissipation holes, cool air from the wind chamber is directly blown onto the electronic components at the top of the control circuit board. Guided by the guide plates, the air exits through the rear heat dissipation holes, quickly removing the heat generated by the electronic components. The spaced arrangement of the guide plates also facilitates airflow. Furthermore, this utility model includes a heat sink and multiple heat dissipation fins attached to the bottom of the control circuit board. This allows for rapid heat dissipation at the bottom of the control circuit board while cool air is blown onto the top, effectively improving heat dissipation and ensuring the normal operation of the electronic components. The overall design is ingenious and highly practical.
[0013] It should be noted that the structures not described in this utility model are not related to the design points and improvement directions of this utility model, and are the same as or can be implemented using existing technology, so they will not be elaborated here.
