Automotive Infotainment System with Thermally Efficient Optical Drive

Abstract

The present application discloses a DIN slot specification infotainment system for a car dashboard having a DIN slot opening. The DIN slot specification infotainment system is provided with a supply air area and an exhaust air area. The infotainment system includes an optical disc drive having an optical drive housing, an optical drive mechanism, and at least one electronic component. The optical disc drive housing includes a supply air inlet and an exhaust air outlet, wherein the supply air inlet is disposed in communication with the supply air area, and wherein the exhaust air outlet is disposed in communication with the exhaust air area. The disc drive mechanism comprises a disc receiving area for driving an optical data carrier disc, wherein the disc receiving area is connected with a supply air inlet and an exhaust air outlet such that when the optical data carrier disc arranged in the disc receiving area rotates, A cooling air flow is generated between the air inlet and the exhaust air outlet. The at least one electronic component is arranged in a region between the supply air inlet and the exhaust air outlet, wherein the at least one electronic component is arranged such that the cooling air flow is in contact with at least one surface area of ​​the at least one electronic component.

Description

Background technique [0001] Automotive infotainment systems provide more and more features and connectivity functions as technology develops and consumer expectations increase, resulting in greater heat generation from added electronic components. For greater heat generation in the same space volume in a system, especially a 1-DIN system, a more efficient cooling method is required. [0002] The DIN standard was originally established by the German standards organization "German Standards Institute" as DIN 74590, and is therefore commonly known as the "DIN car radio specification". It was adopted as the international standard ISO7736 in 1984. Head units typically go through 1st, 2nd, 2.5th and 3rd generation DIN configurations. In particular, these configurations include single DIN (180x50mm panel) and double DIN (180x100mm panel) sizes. Depth is not normalized. [0003] Specifically, when an infotainment system's CD drive is reading and playing a song from a loaded disc, ...
