Description
Technical Field
The invention relates to the technical field of automobile manufacturing, in particular to a heat dissipation structure of an intelligent driving area controller.
Background
With the development of automobile intelligence, automatic driving gradually becomes the mainstream of the market, and the automatic driving technology relies on various sensors at the front end to provide scene and vehicle information, including various sensors such as a visual camera, a millimeter wave radar, an ultrasonic radar, a laser radar, a speedometer, high-precision positioning, an inertial device and the like, and a high-precision map. The rapidly increased number of sensors and the complexity of the wire harness pose a great challenge to an Electronic Control Unit (ECU) and an electronic electrical architecture in the traditional automobile field, a centralized architecture scheme for gradually replacing a distributed architecture becomes a mainstream direction of future development of an automobile architecture, and an ADAS domain controller with high integration level and high calculation power for replacing the traditional ECU is a better solution at the present stage. The higher the calculation power of the ADAS domain controller is, the higher the energy consumption is, and therefore, the higher the heat dissipation requirement of the core processing chip is put forward.
At present, the ADAS domain controller on the market generally adopts fan heat dissipation or water cooling heat dissipation. The heat dissipation reliability of the fan is low, and the fan generates large noise and is easy to damage; dust is easy to accumulate and difficult to clean, and the heat dissipation effect is gradually reduced along with the change of time; and the adoption of the scheme design also causes the domain controller to be difficult to meet the higher protection (waterproof and dustproof) grade. The scheme of the independent water cooling head of the existing ADAS domain controller is only basically directed at a core processing chip, a water path adopts a combination mode of a nylon/silica gel water pipe and a quick connector, and the design scheme cannot completely isolate a cooling water path from a PCB assembly board, so that the water leakage risk of the water pipe cannot be completely avoided; meanwhile, the flow cannot be accurately controlled due to the limitation of the specifications of the water pipe and the quick connector product. Therefore, it is necessary to design a heat dissipation structure of the ADAS domain controller, so as to ensure the reliability of the heat dissipation system of the ADAS domain controller and increase the design freedom of the cooling system.
Chinese patent application publication No. CN113905580A, published as 2022, year 01, month 07, entitled "ADAS domain controller integrated water-cooling heat dissipation structure", discloses an ADAS domain controller integrated water-cooling heat dissipation structure, which comprises an outer shell and an upper cover, wherein the outer shell is provided with a water inlet channel, a water collection tank and a water outlet channel which are sequentially communicated, the upper cover is fixed on the outer side of the outer shell in a sealing manner, and the upper cover covers the water inlet channel, the water collection tank and the water outlet channel. The invention provides an integrated water-cooling heat dissipation structure of an ADAS domain controller, which can enable the ADAS domain controller to dissipate heat integrally, and is integrated with water cooling, high in integration level and good in heat dissipation effect; and the liquid cooling system is completely isolated from the PCB assembly board, so that a better protection effect is realized. The heat dissipation shell adopts a water cooling heat dissipation mode, but circulation water paths such as a water inlet channel, a water outlet pipe and a water outlet channel are integrated in the shell body, and an integrated die-casting molding mode is adopted, and a pipeline needs to be drawn out through machining after die-casting is completed to form a water path, so that the working time is increased, the manufacturing difficulty is improved, the working procedures are increased, the manufacturing cost is further increased, and the production efficiency is greatly reduced; the right 7 describes that the upper cover and the sealing ring are molded into an integral structure through a secondary injection molding process, the upper cover and the outer shell are installed together, a circulation water channel is formed in a space between the upper cover and the outer shell, the upper cover is made of plastic, the outer shell is made of metal, the expansion coefficients of the upper cover and the outer shell after being heated are different, gaps are easily generated, cooling water is leaked, the domain controller is damaged or crashed easily due to untimely heat dissipation, an automobile cannot be assisted to run, and even traffic accidents caused by the fact that the automobile is out of control are caused; in addition sealing washer and upper cover integrated into one piece change the sealing washer and just need change whole upper cover, and the use cost of replacement spare part promotes greatly, and the maintenance cost promotes, is unfavorable for the domain controller to sell.
