A vehicle-mounted multimedia electronic system with a heat dissipation function

Abstract

The invention discloses a vehicle-mounted multimedia electronic system with a heat dissipation function, which comprises a circuit board, a heat dissipation component and electronic components. Wherein the electronic components comprise a digital logic component, a power supply component and a high heat consumption component, and the heat dissipation component is tightly coupled with the electronic components; the circuit board adopts an area division design, comprising a digital logic element partition, a power element partition, a high heat consumption element partition and a heat dissipation component area; the digital logic element partition is remote from the high heat consumption element partition, and the high heat consumption element partition and the heat dissipation component area are adjacent to each other. In addition, a corresponding auxiliary heat insulation device can be arranged at the periphery of the high heat consumption element partition. The invention adjusts the internal structure of the vehicle-mounted multimedia electronic system, and combined with the heat dissipation parts used together, the stability and reliability of the system operation are effectivelyimproved.

Description

technical field [0001] The invention belongs to the field of vehicle-mounted multimedia products, in particular to a vehicle-mounted multimedia electronic system with its own cooling function. Background technique [0002] With the increasingly powerful functions of the vehicle multimedia system, its hardware structure is also developing towards miniaturization, complexity and precision, which poses a huge challenge to the heat dissipation management of the system. Based on the data of the U.S. Air Force Avionics Research Project, failures caused by temperature factors account for about 55% of electronic product failures. Due to the compact arrangement of electronic components on the circuit board, and high heat consumption electronic components will emit a large amount of heat when they are working. If the heat cannot be effectively discharged, it will affect the working performance of the system and even cause irreversible damage to the electronic components. Shortened se...
