Work vehicle perception systems and rear modules

A rear perception module utilized in conjunction with a work vehicle having a work vehicle cabin and a cabin roof, the rear perception module comprising:

• an environmental depth perception (EDP) sensor system comprising a first EDP device having a field of view (FOV) encompassing an environmental region to a rear of the work vehicle;
• a rear module housing mounted to an upper trailing edge portion of the cabin roof, wherein the rear module housing comprises a central housing body in which the heat-generating electronic component is located, a first wing section extending from the central housing body in a first lateral direction, and a second wing section extending from the central housing body in a second lateral direction opposite the first lateral direction, wherein the first wing section and the second wing section each include an enlarged terminal end extending in a forward direction relative to a rear window of the work vehicle cabin such that the rear module housing wraps around a trailing upper edge portion of the work vehicle cabin;
• vents formed in exterior walls of the rear module housing to facilitate airflow through the rear module housing along a cooling airflow path;
• and
• a heat-generating electronic component electrically coupled to the first EDP device, the heat-generating electronic component positioned in or adjacent the cooling airflow path such that excess heat generated by the heat-generating electronic component is dissipated by convective transfer to airflow conducted along the cooling airflow path during operation of the rear perception module.
