Active Thermal Management of Automotive Camera Components

Abstract

This study is about the thermal management of camera component in vehicle cockpit. A thermal management is necessary because it is directly related to abnormal operation and user's safety, if the camera components have a high temperature. The highest temperature component among the camera module is camera multi-processor chip, the forced convection is used to reduce the temperature of the component in the vehicle stage. The most commonly used method of the forced convection in the vehicle stage is a fan control using ducts. In the vehicle stage, the duct location is normally fixed and limited for changing. In the limited systems, a method of adding or removing the number of the vent and a controlling the direction of the air using the duct are proposed. In addition, the flow-guide is designed and also proposed to control the direction of flow. The number of vents controls the flow to the outlet, while the guide directly controls the flow direction to provide a cooling solution for the heat generation. As the same methodology, this study can provide a fan flow solution to control high temperature of camera components.
