Vehicle platforms and thermal management systems, subsystems, and components for use therewith are described. Thermal management architectures and systems incorporate thermal management cycles for one or more of drive train, energy storage and passenger cabin systems. Thermal manage architectures are provided such that the flow of heating and cooling fluids through such thermal management cycles may be combined in various configurations. Systems having thermal management cycles for drive train (e.g., motor, transmission, etc.) and energy storage (e.g., battery) that may be operated through a combined heating/cooling fluid loop are also provided. Embodiments are also directed to systems having thermal management cycles for the HVAC that is fluidly isolated, but thermally coupled to one or both of the drivetrain and energy storage components. Heating/cooling loops for these thermal management cycles may be functionally linked through one or more valves such that the fluid flow through such cycles may be combined together, isolated from each other or mixed in various desired configurations.

A pressure relief valve flap includes an attachment portion, a main portion, and a hinge portion. The attachment portion is configured to be attached to the housing. The main portion has a lip and at least one damping feature. The lip extends around at least a portion of a periphery of the main portion. The hinge portion is disposed between and connects the main portion and the attachment portion. When the attachment portion is attached to the housing, the main portion is configured to move between a closed position and an opened position. When the main portion moves from the opened position to the closed position, the at least one damping feature is configured to engage the housing prior to the lip of the main portion and thereby dampen noise created when the lip of the main portion engages the housing.

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 low sound emission flow diffuser includes a diffuser housing, which limits or forms an installation space, through which a flow path for an air flow of air extends, starting at an inlet opening, which is limited or formed by the diffuser housing on its inflow side, to an outlet opening, which is limited or formed by the diffuser housing on its outflow side. The flow diffuser has a multi-piece, optionally three-piece, flow manipulator, which extends along the flow path between the inlet opening and the outlet opening, for absorbing airborne sound. The disclosure additionally relates to an air conditioning system of a motor vehicle including at least one such low sound emission flow diffuser.

The motor support (16) for a motor-fan unit of a ventilation installation for a vehicle comprises: two coaxial rings (20; 22), including an inner ring (20) capable of receiving one or more elements of the motor and an outer ring (22) capable of fixing fastened to a housing forming a structural element, a decoupling element (24) between the two coaxial rings (20; 22); and a means (44) for limiting the relative movement of one of the two rings (20:22) relative to the other, in a plane normal to the common axis (A) of the two rings (20; 22) comprising at least one radial abutment (44) fastened to one of the two rings (20; 22), with a radial clearance between the radial abutment (44) and the other of the two rings (20; 22).

A lining component for lining a passenger cell of a motor vehicle is multifunctional. The lining component has at least one acoustic resonator which is open towards the passenger cell and/or at least a fluid chamber through which a temperature control medium is flowable.

Disclosed is a blowing unit of an air conditioner for a vehicle, having a two-layer structure and capable of effectively suppressing a flow of air flowing backward around a scroll bell mouth. In a blowing unit of an air conditioner for a vehicle, having a scroll case in which a first flow path and a second flow path are partitioned so as to separate inside and outdoor air to be sucked, the scroll case has a partition wall for separating a suction part of the first flow path and a suction part of the second flow path, and the partition wall has an air backflow prevention part for preventing air flowing into one of the first flow path or the second flow path from flowing backward into the other.

A recreational vehicle and an air conditioner therefor are provided. The air conditioner includes an indoor cover defining an indoor portion and an outdoor portion with an outdoor heat exchanger and an outdoor fan disposed in the outdoor portion and an indoor heat exchanger and an indoor fan disposed in the indoor portion. The air conditioner also includes an indoor panel defining an air inlet and an air outlet. An acoustic insert includes a solid top wall and at least one permeable side wall. The acoustic insert is positioned between the indoor panel and the indoor fan, whereby the acoustic insert dampens sound transmitted through the indoor panel.

The present invention relates to an air conditioner for a vehicle, which includes an air-conditioning case (200), and at least one door (100) mounted to be opened and closed at a predetermined position, wherein the door (100) is formed integrally with an arm pivot (140), and the arm pivot (140) includes a pin part, and ribs formed integrally with both sides of the pin part to reinforce rigidity of the pin part and offset noise. The air conditioner further includes distortion preventing parts formed on a rotary shaft to be dented and to be crossed to each other, thereby reducing a transformation rate of the door and securing accuracy of the pin part.

An air-conditioning unit includes an air-conditioning case including an opening through which air flows, a cooler disposed in the air-conditioning case to cool air flowing to the opening, a heater disposed in the air-conditioning case to heat air flowing to the opening, and an adjusting member disposed to cover the opening and adjusting airflow passing through the opening. The adjusting member is produced separately from the air-conditioning case and includes a first region and a second region. The second region includes a high resistance member giving higher resistance to the airflow than the first region. The first region includes a low resistance member giving lower resistance to the airflow than the second region. The low resistance member is a partition dividing the first region into plural air passing parts through which air flows. The high resistance member is a plate member including a part to interfere the airflow.
