Car entertainment system cooling fan

With the development of electronic technology, automobiles have gradually become an extension of home entertainment and office environments. After the originally independent consumer and communication applications entered the field of automotive electronics, new integrated applications continued to appear. In addition to functions such as high-definition/high-fidelity content playback and digital TV, in-vehicle information communication entertainment system, in-vehicle GPS navigation, mobile phone (GSM/GPRS), information connection, short-range communication (Dedicated Short Range CommunicaTIon, DSRC) and high-level data connection Control (High Level Datalink Control, HDLC) has gradually become an important part of the system. The TelemaTIcs system is an integrated service that combines GPS, GSM/GPRS, DSRC, and traffic information digital broadcasting. It can provide real-time road condition navigation, avoid congested road sections and determine the best driving route, provide car status diagnosis, Diversified value-added services such as lost car recovery, reserved parking space, electronic toll collection (Electronics Toll CollecTIon, ETC) and emergency calls.
With the continuous increase of the functions of the car entertainment system, the heating elements have also increased accordingly. The heat dissipation design of the heating elements directly affects the normal use of the entertainment system, especially whether it can pass the 70°C high temperature test. Therefore, the use of natural cooling can no longer meet the heat dissipation requirements of the product, and it is necessary to add a cooling fan for forced cooling. The use of a heat dissipation structure with forced cooling by a heat dissipation fan can eliminate heat accumulation, so as to avoid system malfunction or permanent damage.
