An off road vehicle has an air heater with right and left shells surrounding and supporting a core, with the right and left shells connected by screws extending through ears on one of the shells into bosses on the other shell. Dual air control plates are mounted in the shell on a shaft for pivoting movement. An actuator is linked to the shaft by a swing arm with a guide pin riding in an arced slot of a drive plate rotationally secured to the shaft. The right and left shells are secured to the vehicle using a resilient compressible grommet, with a bushing extending through the grommet and a bolt extending through the bushing and attached into the frame.

An air conditioning unit for a vehicle includes an air conditioning case, a blower, a cooler including a core, and a drain port that drains condensed water generated in the cooler from the air conditioning case. A bottom surface of the air conditioning case defines a drain path extending from a boundary between the blower and the air conditioning case to the drain port. The drain path is inclined downward toward the drain port. A backflow prevention rib protrudes from the bottom surface to extend along a direction intersecting with a width direction of the air conditioning case. The backflow prevention rib is configured to guide the condensed water to the drain port. The backflow prevention rib is located below a virtual line that extends from the boundary to a lower end of an upstream surface of the core.

An interior structure for a vehicle includes an instrument panel disposed below a windshield, an air conditioning duct provided inside the instrument panel, and a head-up display device having a housing structure and mounted to the instrument panel, the head-up display device being configured to project information on the windshield. The head-up display device has a heat dissipating portion on an outer peripheral face of the housing. The air conditioning duct has a facing portion that faces the heat dissipating portion so as to be able to exchange heat with the heat dissipating portion.

An HVAC module is mounted in a front compartment of a vehicle, proximate a wall that separates the front compartment of the vehicle from a passenger cabin of the vehicle. The HVAC module includes an intake and blower section that receives air from the passenger cabin or from outside the vehicle and provides it to a conditioning and distribution section of the HVAC module, which selectively conditions the air with heating or cooling equipment and distributes the conditioned air to the passenger cabin.

The present invention relates to an air conditioning system for a vehicle in which an air-conditioning module having an air-conditioning case and a blower unit is disposed at a side of an engine room relative to a dash panel, and a distribution duct having a defrost vent, a face vent, and a floor vent is disposed in the interior of a vehicle relative to the dash panel so as to distribute cold air and hot air discharged from the air-conditioning case into the interior of the vehicle, wherein the floor vent is placed on one side of an area, in which a relatively large amount of hot air flows, in a mixing chamber of the distribution duct where cold air and hot air are mixed, i.e. a side adjacent to the dash panel.

A vehicle heat exchange system includes a cooling heat exchanger provided in a cooling water circuit, a first air-conditioning heat exchanger as an evaporator in a heat pump system, a hydrothermal-medium heat exchanger as a refrigerant condenser in the heat pump system, a second air-conditioning heat exchanger, and an air conditioning passage in which the first air-conditioning heat exchanger and the second air-conditioning heat exchanger are disposed. A vehicle interior-exterior communication port is provided at a downstream side of the second air-conditioning heat exchanger in the air conditioning passage, to guide the air having passed through the second air-conditioning heat exchanger, to an outside of the vehicle interior. The cooling water for cooling the heating element flows through the second air-conditioning heat exchanger, and the air having passed through the second air-conditioning heat exchanger is discharged outside the vehicle interior through the vehicle interior-exterior communication port.

A thermal management system for a vehicle includes a heat exchange unit coupled with a compartment of the vehicle via an interface in the compartment. A container is moveable between a first position and a second position. The container is configured to be in fluid communication with the heat exchange unit via the interface in the first position.

A temperature control system includes a heater core utilizing heat of a heat medium; an engine heat exchanger utilizing exhaust heat of an engine to heat the heat medium; a condenser utilizing heat other than the exhaust heat to heat the heat medium; a heat circuit having the heater core and condenser; a communication flow path making the engine heat exchanger communicate with the heat circuit; and a connection state switching mechanism switching a flow state of the heat medium, between a first state and a second state. In the first state, the heat medium flows through the heat circuit, while flowing through the heater core, and in the second state, the heat medium flows through the heat circuit without flowing through the heater core. The heat circuit is arranged at a front of a passenger compartment, and the engine heat exchanger is arranged at a rear of the compartment.

An air flow distribution device of a driver HVAC unit is described. The air flow distribution device can direct conditioned air flow into a space of a housing of the air flow distribution device via an air inlet of the air flow distribution device. A single motor of the driver HVAC unit can control an orientation of an air flow distribution mechanism of the air flow distribution device. Based on the orientation of the air flow distribution mechanism, the air flow distribution mechanism can direct the conditioned air entering the space via the air inlet to exit the housing via one of the window air module, the head air module, and the foot air module of the air flow distribution device.

The invention relates to a motor vehicle having a water tank (10) with a first inner chamber (23) for separating and conducting away water from a first air flow (15) flowing through the first inner chamber (23). The water tank (10) is designed as a heat exchanger, comprising a heat exchanger element (20) for transferring thermal energy between the first air flow (15) and a second air flow (50). At least one guide structure (8) is provided for guiding the second air flow to the heat exchange element (20) in a targeted manner. In addition, at least one control element (34) is provided, with which the transfer of the thermal energy between the first air flow (15) and the second air flow (50) can be enabled in a first operating state, and can be at least partially inhibited in a second operating state.
