An air vent for a motor vehicle includes a housing with an air channel for feeding air and a partial hemisphere shell. The partial hemisphere shell is mounted in a rotatable manner within the housing such that air fed through the air channel is deflected on the housing before it exits from the air vent.

An air conditioner for a vehicle includes: a casing to accommodate a cooler and a heater; a front temp door disposed in the casing to control a temperature of air supplied to a front seat zone; a rear temp door disposed under the front temp door to control a temperature of air supplied to a rear seat zone; and a rear vent disposed at a lower portion of the casing to discharge air to the rear seat zone. The air conditioner can secure the flow rate of the air that is supplied to the rear seat zone of the interior of a vehicle by improving the route for flow of the air that is supplied to the rear seat zone.

A noise suppression structure to be mounted on a cooling system for an electrical device of a vehicle includes a duct, a blower, and a sound absorber. The duct extends from inside a vehicle cabin of the vehicle to inside the vehicle cabin or outside the vehicle cabin through the electrical device. The blower is configured to draw air from the vehicle cabin into the duct and feed the air to the electrical device. The sound absorber is disposed in the duct. The duct has a curved portion where an extension direction of the duct changes. The curved portion is located on one of or each of an upstream side and a downstream side of the electrical device. The sound absorber is disposed in a fluid stagnation region where a flow of the air tends to stagnate in the curved portion.

The invention relates to a ventilation device for a vehicle ventilation, heating and/or air-conditioning system, including at least one housing that includes at least one wall defining an inner volume in which at least one radial propeller capable of being rotated and at least one guide member are received, the radial propeller and the guide member being configured to generate an air flow having a general direction parallel to an axis of rotation of the radial propeller between an air inlet of the radial propeller and an air outlet formed in the wall of the housing of the ventilation device, at least a part of the wall of the housing being configured to straighten the air flow at the outlet of the radial propeller. The guide member is configured to direct the air flow towards the axis of rotation of the radial propeller.

A HVAC system (100) includes a housing (10) with at least one first inlet (20) and at least one second inlet (30) formed thereon, at least one first door (20a), at least one second door (30a) and an intermediate door (40). The first inlet (20) and the second inlet (30) is for ingress of a first fluid stream and a second fluid stream inside the housing (10). The first door (20a) and the second door (30a) moves with respect to the first inlet (20) and the second inlet (30) respectively to define an open configuration, a closed configuration and a partially open configuration thereof. The intermediate door (40) is disposed between the first inlet (20) and the second inlet (30) and moves between a deployed and an un-deployed configuration to respectively disrupt and allow fluid flow there across. The intermediate door (40) is a sliding door.

Disclosed is an air conditioning apparatus for a vehicle, the air conditioning apparatus being applicable to an autonomous vehicle, etc. having console removed therefrom by ensuring a lower space of a driver's seat in a front part of the vehicle and being capable of preventing condensate water from flowing backward. The air conditioning apparatus for a vehicle comprises: an air conditioning case having an air flow path formed therein and a plurality of air discharge ports; and a cooling heat exchanger and a heating heat exchanger provided in the air flow path of the air conditioning case and exchanging heat with the air passing through the air flow path, wherein the air discharge ports include a front seat air discharge port and a back seat air discharge port, and the back seat air discharge port is arranged under the heating heat exchanger in the direction of gravity.

The invention relates to a heating, ventilation and/or air conditioning device for a motor vehicle, having an air inlet box with a plurality of walls and a spiral box arranged downstream of the air inlet box with respect to the flow of an air flow. The air inlet box further includes at least one first air inlet for the entry of a first air flow and at least one second air inlet for the entry of a second air flow. The air inlet box has a first internal duct made of porous material arranged to connect the first air inlet to the inlet of the spiral box.

A mounting structure of a thermal management module for a vehicle, includes: a mounting carrier mounted at a front of a vehicle body and having a receiving space; and a thermal management module mounted in the receiving space; wherein the thermal management module includes: an air conditioner mounted in the receiving space and configured to adjust a temperature of a vehicle interior according to a cooling mode or a heating mode; and a cooling device mounted in the receiving space and configured to heat-exchange with a working fluid using an external air introduced from outside of the cooling device.

An air conditioner includes an air conditioning case, a blower fan, and a facing wall portion. The air conditioning case configures an air passage through which air to be blown into an interior flows. The blower fan is disposed inside the air conditioning case. The facing wall portion is disposed on an air flow upstream side of the blower fan to face a suction port of the blower fan. The air conditioning case has a facing surface that faces the facing wall portion and in which through holes are formed. The air conditioning case has a closed space formed therein on an opposite side of the facing surface with respect to the air passage and communicating with the air passage via the through holes. The through holes and the closed space form a resonator having a predetermined resonance frequency.

This air-conditioning device (10) for a vehicle comprises a flow path width adjustment portion (14) that is provided at an inlet portion (11BA) of a ventilation flow path (11B) so as to be connected to the inner surface (31a) of a first side wall (31), the flow path width adjustment portion (14) having an upper end connected to a fan mounting portion (35), extending downward, and being located between a third wall (33) and a nose portion (37) in the (Y) direction. The nose portion (37) has an inclined portion (37A) that is inclined with respect to the third wall (33) such that the width of the inlet portion (11BA) increases in the (Z) direction from the inlet to the outlet of the inlet portion (11BA) of the ventilation flow path (11B). In the (Z) direction, the flow path width adjustment portion (14) is formed so as to narrow the width of the inlet portion (11BA) of the ventilation flow path (11B) in the (Y) direction.
