Heat dissipation module of compact disc read-only memory driver core in auto sound

Abstract

The invention relates to a heat dissipation module of a compact disc read-only memory driver core in an auto sound; the heat dissipation module is formed by a sound case; the sound case comprises an upper cover plate, a heat sink, a front cover plate, an upper shell and a lower shell, wherein the upper shell is arranged above the lower shell; the heat sink is connected at rear sides of the upper shell and the lower shell; an air outlet of a fan is arranged in the heat sink; an air vent is arranged in the upper cover plate; an air vent is arranged in a baseplate of the upper shell; and the air vents are communicated with the cavity of the lower shell; a heat insulation baffle is arranged at the back of the upper shell; the heat insulation baffle is vertical to the baseplate and is parallel to the heat sink at an interval; and the heat insulation baffle is arranged behind the air vents. Air vents are respectively arranged at two sides of the upper shell and the lower shell. The heat insulation baffle inhibits the transmission of heat from the heat sink to the driver core; air sucked by the fan forms two flowing air currents between the heat sink and the heat insulation baffle and between the heat insulation baffle and the compact disc read-only memory driver core, thereby further the transmission of heat to the core is blocked; the fan dissipates heat of a main board and simultaneously promotes the heat insulation of the compact disc read-only memory driver core, and the fan is utilized in a maximum degree.

Description

Technical field [0001] The invention relates to the field of electricity, in particular to an optical disc player, in particular to a heat dissipation module for a car audio optical disc movement. Background technique [0002] The optical disc core of the car audio and the main circuit board of the car audio are assembled in the audio chassis together. The main function of the optical disc core is to read the data stored on the optical disc. The parts of the optical disc core are assembled in a high degree of airtightness. In the sheet metal shell of the optical disc, and then assembled in the chassis shell, the heat exchange between the internal heating element of the optical disc core and the outside is more blocked, and the effect of direct heat dissipation measures for the optical disc core is very limited. For the optical disc drive, most of its internal components can work normally if they are only affected by its own heating, but if the working temperature rises due to the...

AI Technical Summary

Problems solved by technology

Due to the small design space of the entire chassis product, the CD-ROM core is usually closer to the radiator, and the heat from the back of the radiator is transferred to the inside of the chassis. Due to the high airtightness of the whole chassis, the internal air flow is slow, and the heat exchange with the outside If less, the working temperature of the disc core will increase accordingly. In addition, the disc core itself will generate a lot of heat when reading the disc. If the heat from the radiator cannot be effectively isolated, the temperature of the disc and electronic components in the disc core will rise too much. High, unable to meet the use requirements
