Vehicular cooling system for forward camera module

A vehicular vision system, the vehicular vision system comprising:

• a camera module configured for mounting at an in-cabin side of a windshield of a vehicle equipped with the vehicular vision system;
• wherein the camera module comprises an imager assembly and a processor circuit board;
• wherein the camera module comprises circuitry, and wherein the circuitry includes an image processing chip at the processor circuit board;
• wherein the imager assembly comprises an imager circuit board, and wherein an imager is disposed at the imager circuit board;
• wherein the imager assembly, with the camera module mounted at the in-cabin side of the windshield of the vehicle, views through the windshield and forward of the vehicle;
• wherein the imager captures image data, and wherein the image processing chip processes image data captured by the imager;
• wherein the circuitry of the camera module generates heat when the circuitry is electrically operated;
• wherein the camera module comprises a temperature sensor;
• wherein an airflow source of a heating, ventilation and air conditioning (HVAC) system of the vehicle is in fluid communication with a vent at an interior portion of the vehicle, and wherein the vehicular vision system is operable to control the HVAC system of the vehicle to direct airflow via the vent along a portion of the camera module;
• wherein, when the circuitry of the camera module is electrically operated, and when the vehicular vision system controls the HVAC system to direct airflow via the vent along the portion of the camera module, heat generated by the circuitry during operation of the circuitry of the camera module is dissipated;
• wherein the vehicular vision system controls the HVAC system to direct airflow via the vent along the portion of the camera module responsive to an output of the temperature sensor being indicative of the circuitry of the camera module operating outside of a set operating temperature range;
• and
• wherein a thermally conductive connecting element thermally conductively connects to (i) a windshield-interfacing portion of the camera module and (ii) the circuitry of the processor circuit board.
