Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of vehicle components, in particular to a kind of heat dissipation structure of automobile active acoustic management controller. BACKGROUND

[0002] Automobile active acoustic management controller is an intelligent electronic device, it is as the core component of automobile active sound management system (Active Sound Management, ASM), through advanced algorithm and real-time audio processing technology to monitor and adjust the sound environment inside vehicle. The controller can analyze engine operating state, speed and other related data, accurately generate compensatory sound waves to reduce unpleasant noise or enhance the sound of specific frequency, such as the roar of engine, so as to optimize the auditory experience in the cab. In addition, it also supports personalized sound settings in different driving modes, to ensure that the best sound experience can be provided whether in quiet cruise or sports driving. In the current automobile active acoustic management controller, its output power is generally within 100W.

[0003] The heat dissipation structure of automobile active acoustic management controller is generally the shell of automobile active acoustic management controller. In the prior art, such as patent application number CN202121960622.0, a controller shell of automobile active sound management system, as shown in the description of its patent and Figure 1 and Figure 5 It is described in the content of the specification. On the outer surface of the controller shell, a total of 5 surfaces, i.e. 1 front surface and 4 side surfaces, are evenly designed with inclined rows of fins. The fins are used to dissipate heat from the automobile active acoustic management controller. However, such arrangement of fins has small heat dissipation capacity per unit area, and needs to be evenly arranged on each outer surface. This not only increases the cost of manufacturing the controller shell, as each surface needs to be manufactured using a mold, but also increases the number of fins, the weight, and the space volume, which does not meet the current goal of pursuing lightweight vehicles.

[0004] In other prior art, to reduce the volume and weight of the heat dissipation shell, a plurality of heat dissipation holes are provided on the surface to achieve the purpose of heat dissipation. However, the automobile active acoustic management controller mainly generates a large amount of heat from the internal MCU and power amplifier during operation, and the purpose is to dissipate heat from the MCU and power amplifier. Such heat is a conductive heat, which conducts heat along the surface it contacts. The heat dissipation holes are used to conduct heat from the entire controller internal space to the outside, and cannot dissipate most of the heat generated by the MCU and power amplifier. This reduces the operating efficiency of the MCU and power amplifier. UTILITY MODEL CONTENT
