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 work

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 electrical field, in particular to a CD player, in particular to a cooling module for a car audio CD core. Background technique [0002] The disc movement in the car audio and the main circuit board of the car audio are assembled in the audio case together. The main function of the disc movement is to read the data stored on the disc. The parts of the disc movement are assembled in a highly airtight In the sheet metal shell, and then assembled in the chassis shell, the heat exchange between the heating element inside the optical disc core and the outside world is more blocked, and the effect of the heat dissipation measures directly aimed at the optical disc core is very limited. For the optical disc movement, most of its internal components can work normally if it is only affected by its own heating, but if the working temperature rises due to the influence of other heating elements in the chassis, it will cause the read ...
