A diffusing vent assembly may include a diffuser base and a diffusing head. The diffuser base may include a mounting flange, a collar extending from the mounting flange, and a ductwork fixation channel. The collar may span an infra-ceiling space of a vehicle. The diffusing head may include a diffuser vane configuration, a rotational flange surrounding the diffuser vane configuration, and an air blade. The diffuser base and the diffusing head further comprise complementary rotational securement members that permit rotation of the diffusing head relative to the diffuser base. The air blade may extend through the collar of the diffuser base. Installing the diffusing vent assembly may include engaging the ductwork fixation channel with a supply duct, inserting the diffusing head into the diffuser base, and securing the diffusing head and the diffuser base using the complimentary rotational securement members.

Heat exchangers, such as radiators, condensers, or other cooling systems, are provided in the present disclosure. Heat exchanging systems may include an assembly for routing cooling conduits from the heat exchanger, along or through one or more A-pillars of the vehicle, and to a rooftop electronics assembly, which may be used for performing self-driving functions when the vehicle is configured as an autonomous vehicle or the like. The conduit routing assembly enhances manufacturing efficiency and cost effectiveness as compared to conventional assemblies. According to one embodiment of the present disclosure, an assembly for cooling a rooftop electronics assembly of a vehicle may include one or more conduits configured to transport a cooling fluid between an in-vehicle cooling system and the rooftop electronics assembly, wherein the one or more conduits are disposed partially along an A-pillar of the vehicle.

A roof-type air conditioner for vehicles may include an evaporator to discharge cold air to the internal of a vehicle, and a conveying unit to move the evaporator in a longitudinal direction of the vehicle on a ceiling of the vehicle such that the evaporator is disposed to the ceiling of the internal of the vehicle and positioned to a region required for cooling.
