Abstract
A camera module for a vision system of a vehicle includes a housing, a lens and at least one circuit board having circuitry disposed in the housing with an imaging array sensor disposed at the circuit board. An elongated thermally conductive element has a first portion in thermal conductive contact with the circuit board and a second portion extending from the first portion towards and through the housing such that the second portion protrudes through an aperture through the housing and protrudes from the housing exterior of the camera module. A heat sink is disposed exterior of the housing. The second portion of the thermally conductive element protrudes at least partially into the heat sink and is in thermally conductive contact with the heat sink. The thermally conductive element is configured to transfer heat from the circuit board to the heat sink to reduce heat within the camera module.
