An on-vehicle air conditioner includes a suction port disposed on a ceiling of a vehicle cabin to suction air within the vehicle cabin, a door discharge port disposed at an upper end of a door opening portion located on a wall face of the vehicle to discharge air downward, and an upper duct configured to guide to the door discharge port the air suctioned by the suction port.

In a vehicle, a flow adjusting plate is placed along an upper edge part of a front windshield, so that the flow of wind flowing along an inner surface of the front windshield is adjustable by the flow adjusting plate. Further, the angle of the flow adjusting plate from the inner surface is adjustable, so that the flow adjusting plate allows the direction of the wind flowing along the inner surface to be directed toward a seat placed behind an instrument panel in the vehicle front-rear direction.

An air filtration system for a mobile unit having a vent fan and a kit for forming the air filtration system. The air filtration system includes a rigid outer cover made, a filter box, and a vent fan installed on a roof of the mobile unit. An air inlet passageway is formed in the rigid outer cover so that the vent fan may draw outside air through the filter box and into an interior space of the mobile unit. The air inlet passageway may include a louver for allowing air entry while protecting the filter box from rainwater. A base plate has a central opening that is positionable around a vent fan housing and securable to a vent fan flange to form a flat surface upon which to receive the filter box and the rigid outer cover.

A vehicle headliner air duct assembly includes a headliner having a first surface and a second surface. A radiused edge is defined between the first surface and the second surface. A headliner duct is coupled to the first surface and the second surface of the headliner. The headliner duct defines an inlet. The inlet is disposed on the radiused edge. A connector duct is coupled to a vehicle body and at least partially overlaps the headliner duct proximate to the inlet to form a duct interface. The connector duct defines an outlet disposed on the radiused edge. The outlet is in fluid communication with the inlet via the duct interface. The duct interface is disposed on the radiused edge.

A vent for mobile living quarters has a base and a cover coupled to the base. The cover is connected to the base and pivots about a hinge by a mechanism that is coupled to a moving bar. The moving bar is attached to the cover by fasteners on one end and an alignment tab on the opposite end. The cover is user-replaceable from the top side without having to move or disconnect the mechanism. To replace the cover, fasteners are removed and the cover is pivoted away from the moving bar, where the alignment tab disengages from the cover. The cover is then slidable along the hinge to completely remove the cover from the base. A new replacement cover is slid along the hinge and the alignment tab is engaged with the replacement cover. The cover is pivoted down to a closed position and the fasteners are reinstalled.

A vehicle roof assembly includes a roof that defines an aperture. A heating, ventilation, and air conditioning assembly is selectively disposed within the aperture. The heating, ventilation, and air conditioning assembly includes a housing defining an interior. The housing defines an intake and a vent opening. The intake is defined on a first side of the housing. A fan is disposed within the interior on a second side of the housing. The second side opposes the first side. A duct is disposed within the interior. The duct extends between the first side and the second side of the housing. The duct fluidly couples the intake with the vent opening.

A method for operating an air conditioning system, which may include a heating device, to condition air in a vehicle interior of a motor vehicle. At least one first air path and at least one second air path may each fluidically communicate with the air conditioning system and each open out into the vehicle interior. The method may include guiding the air from the vehicle interior via one of (i) the at least one first air path and (ii) the at least one second air path to the air conditioning system as a function of an operating state set in the air conditioning system. The method may also include guiding the air from the air conditioning system via the other of the one of (i) the at least one first air path and (ii) the at least one second air path into the vehicle interior.

A heat-exhausting device includes a first inlet through which wind generated as a vehicle travels is taken into a housing; and a circulating path for allowing the wind flowing in from the first inlet to be circulated in the housing. A heat-generating portion of a processing unit which is energized to perform a predetermined process is disposed in contact with an outer wall surface of the circulating path.

An air filtration system for a vehicle includes a first inlet assembly. A second inlet assembly is in fluid communication with the first inlet assembly. A first fan is disposed within a housing and is in fluid communication with the first inlet assembly. A second fan is disposed within the housing and is in fluid communication with the second inlet assembly. A light source is disposed within the housing proximate the first and second fans. The light source emits ultraviolet light. A filter is disposed within the housing proximate the first and second fans. An outlet is in fluid communication with the first and second inlet assemblies. Air is drawn into the housing by the first and second fans, subjected to the ultraviolet light, and expelled via the outlet.

A cooling system for efficiently cooling large-scale data storage devices embedded in a vehicle, and a smart vehicle including the same are disclosed. The storage device cooling system includes a storage housing section located at a ceiling-mounted structure of a vehicle, provided with an indoor space thereof in which a plurality of storage devices is kept and an opening/closing device configured to open or close the indoor space, a sensing circuit configured to detect a temperature of the indoor space, and an opening/closing controller configured to control operations of the opening/closing device in response to the temperature detected by the sensing circuit.
