An air distribution arrangement for an air conditioning unit is provided. The air distribution arrangement includes a main body coupled to a housing of the air conditioning unit, and provided with a distribution chamber fluidically connected to at least one air transport conduit formed within the housing of the air conditioning unit, and a plurality of distribution pipes connected to the main body and configured to be connected to respective air outlets for distributing air within a cabin of a vehicle. Each of the distribution pipes is flexible and at least partially inflatable due to an air flow within it.

A sound reducer (10) has a housing (14) with a housing wall bounding an interior space (141). The housing wall has a mantle (142) extending longitudinally along a housing axis. Two end walls (143) are transverse to the housing axis. A main tube (12) extends through the interior space (141) and has a first and second ends (121). Windows (22) are formed as tube wall openings within the interior space (141). The first end (121) of the main tube (12) is fixed at a first passage (18a) through the housing wall, and the second end (122) of the main tube (12) is fixed at a second passage (18b) through the housing wall. At least the second passage (18b) passes eccentrically through one of the end walls (143). The main tube (12) is curved in a main plane and the first passage (18a) passes through the mantle (142).

In an air conditioning case, a blower sucks air flowing out from first and second upstream side ventilation paths from one side in an axial direction of a fan axis by rotation of a blower fan and allows the sucked air to flow to first and second downstream side ventilation paths. An upstream side guide member is provided on one side in the axial direction with respect to the blower fan and guides the air to the blower fan. Further, the upstream side guide member has a twisted shape and guides the air to the blower fan along the twisted shape.

A module for accommodating electronic circuitry which advantageously is able to take advantage of air in a climate system for cooling of the electronic circuitry. In one aspect, there is provided a module for accommodating electronic circuitry in a vehicle, the module includes: at least one attachment surface for attachment of electronic circuitry thereon, an air guiding structure for receiving an air flow for cooling of the attachment surface, the air guiding structure having a wall member including the attachment surface such that the wall member provides a thermal path between the attachment surface and the air in the air guiding structure, wherein the air guiding structure includes an inlet configured to receive air for cooling of the attachment surface wherein the air flow is an air flow used for climate control in the vehicle.

A cooling system includes air intakes, air intake fans, a duct, and an intake-air controller. The air intakes are separately formed near seats disposed side by side inside a vehicle. The air intake fans individually take in air through the air intakes. The duct guides the air taken in by the air intake fans to a battery. The intake-air controller controls a ratio of intake air flow rates in the air intake fans according to the state of a seated occupant.

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.

An air conditioner for a vehicle includes: a case that forms an air passage; and a filter arranged inside the case. The case has an opening for attaching/detaching the filter. The case has a guide unit provided on an inner wall surface of the case to guide a movement of the filter. The guide unit has a positioning portion to determine a position of the filter in a filter mounted state, and a service portion located between the positioning portion and the opening. The case has a water prevention rib protruding from the inner wall surface so as to extend in a direction intersecting a flow of air at a position upstream of the service portion.

A fastening module for connecting a filter system to an arched connecting surface with openings for a fluid has a connecting housing connectable in fluid communication to the filter system. Rigid individual channel pieces are arranged in the connecting housing and channels extend in the channel pieces. The channels correspond with the openings in the arched connecting surface. The channel pieces have connecting flanges to be connected to the openings in the arched connecting surface. The channel pieces are connected by flexible connecting regions with each other; with the connecting housing; or with each other and with the connecting housing. The fastening module is connected in fluid communication to the inlet region or outlet region of the filter system. A filter module for the filter system has substantially free intake across its cross section and enables an intake manifold-type distribution of a volume flow passing through the filter element.

An interior trim panel for a vehicle interior. The panel includes an air distributing member for distributing the air, a first air distribution channel for distributing the airflow from the air distributing member into the vehicle interior. A canopy is configured to partly cover an accessory arranged on the interior trim panel. Further, the interior trim panel includes a second air distribution channel configured in a gap formed between the canopy and the accessory for distributing the airflow from the air distributing member. Further, the air distributing from the second distribution channel is deviated towards the vehicle interior by a curved extension of the canopy.
