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 having circuitry disposed thereat, and wherein the circuitry includes an image processor;
• wherein the imager assembly comprises an imager circuit board, and wherein an imager is disposed at the imager circuit board, and wherein the circuitry disposed at the processor circuit board is electrically connected to the imager 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, and wherein the imager assembly captures image data, and wherein the image processor processes image data captured by the imager assembly;
• wherein the camera module comprises a windshield-interfacing portion that, with the camera module mounted at the in-cabin side of the windshield, interfaces with the in-cabin side of the windshield;
• a thermally conductive tape disposed at the windshield-interfacing portion of the camera module, wherein the thermally conductive tape is adhesively attached at the windshield-interfacing portion;
• wherein the thermally conductive tape adhesively attaches at the in-cabin side of the windshield when the camera module is mounted at the in-cabin side of the windshield;
• a thermally conductive connecting element that thermally conductively connects to (i) the thermally conductive tape disposed at the windshield-interfacing portion and (ii) at least one electrically operated component of the camera module that generates heat when electrically operated;
• wherein the thermally conductive tape and the thermally conductive connecting element comprise graphite strips;
• wherein the at least one electrically operated component comprises the image processor;
• and
• wherein, when the at least one electrically operated component is electrically operated, heat generated by the at least one electrically operated component of the camera module is dissipated at the windshield of the vehicle via the thermally conductive connecting element and the thermally conductive tape.
