TEMPERATURE SENSING DEVICE, CAPABLE OF MINIMIZING A TEMPERATURE DIFFERENCE BETWEEN A MATRIX FAR INFRARED RAY SENSOR AND FAR INFRARED RAY REFLECTOR

摘要

PURPOSE: A device for sensing temperature for vehicle is provided to accurately detect a temperature of indoor and outdoor of a vehicle by minimizing a temperature difference between a matrix far infrared ray sensor and far infrared ray reflector and seclude the inner spaces of a case and a vehicle or contacts between a matrix infrared ray sensor and air inside the vehicle.;CONSTITUTION: A temperature sensing apparatus(100) for a vehicle comprises a matrix far infrared ray sensor(110) and a far infrared ray reflector(130). The matrix far infrared ray sensor comprises a plurality of cells outputting electric signals corresponding to an amount of the infrared ray irradiating. The far infrared ray reflector reflects the infrared ray radiating from a subject inside of a vehicle to the matrix far infrared ray sensor. The matrix far infrared ray sensor and far infrared ray reflector are attached to be faced to each other inside of a case of a thermal conductivity material. At least a part of the case passes through the infrared ray radiating from the subject so that the infrared ray is reached to the far infrared ray reflector.;COPYRIGHT KIPO 2012
