The present invention relates to an air conditioner for a vehicle can enhance sealing performance and is resistant to noise and vibration, and prevent penetration of water into the interior of the vehicle by inducing water introduced into a seal into an air-conditioning case by a pressure difference. The air conditioner for a vehicle, which has a structure that a pipe of a heat exchanger penetrates through a dash panel (150) of the vehicle, includes: a bracket (140) for inserting and fixing the pipe; and a seal (160) for fixing the bracket (140) between an air-conditioning case and the seal to get in contact with the air-conditioning case.

A connection device for interconnecting two components of plastics material is provided. The components include a first wall and a second wall, which have respective edges arranged against one another, when the two components are assembled. The device includes at least one clip on the first wall and extending beyond the edge thereof, at least one first tooth and at least one second tooth on the second wall and designed to be snap engaged by the clip when the two components are in the pre-assembled state and in the assembled state, respectively. The first tooth is closer than the second tooth to the edge of the second wall such that, when pre-assembled, the two components are connected by the edges of the first wall and the second wall, the edges being spaced apart from one another. The first tooth has an inclined locking face for facilitating decoupling of the two components.

An arrangement for sealing functional unit interfaces includes a functional unit, an interface, and a sealing element. The interface has a first main surface, a second main surface, and an opening. The second main surface has a clamping section enclosing the opening. The functional unit has a front face with a counter-clamping section opposite the clamping section. The sealing element has a sealing body and a support element at least partially arranged within the sealing body. The sealing body has a first section clamped between the clamping section and the counter-clamping section. The opening is closed by a second section of sealing body, which is at least partially arranged between the opening and the front face. The support element is partially arranged in the first section and partially in the second section of the sealing body. The support element and the sealing body consist of different materials.

A housing for configuring a compact heat exchanger module includes separate fluid flow conduits integrally formed on at least one wall thereof and connected to at least one inlet and at least one outlet of at least one heat exchanger disposed within the housing. The separate fluid flow conduits configures at least a part of the heat exchange circuit that facilitates passage of fluid cooled/heated by the at least one heat exchanger through at least one region to be cooled/heated to extract/reject heat there-from/thereto and return heated/cooled fluid back to the at least one heat exchanger for cooling/heating thereof.

A split heating, ventilation, and air-conditioning (HVAC) assembly for a motor vehicle is disclosed. The split HVAC includes a first sub-assembly comprising an evaporator and a first airflow space, a second sub-assembly comprising a second airflow space, a single sealing element located between a wall and one of the first sub-assembly or the second-sub-assembly, and a first interfacing element that directly connects the first sub-assembly and the second sub-assembly. The single sealing element and the first interfacing element prevent any airflow leakage from both the first sub-assembly and the second sub-assembly, and one of the first sub-assembly and the second sub-assembly extends partially into the other of the first sub-assembly and the second sub-assembly.

A sealing element having a substantially right-angled exterior corner is formed from a preform. The preform is formed from a strip of sealing material including a first longitudinal side surface having a projection projecting therefrom and an oppositely arranged second longitudinal side surface having a notch formed therein. The notch is aligned with the projection with respect to the longitudinal direction of the strip. A first segment of the strip is formed to a first side of the projection and a second segment of the strip is formed to a second side of the projection. The projection forms the substantially right-angled exterior corner of the sealing element following a bending of the first segment perpendicular to the second segment.

A heating, ventilation, or air conditioning system having a housing , for a motor vehicle having a firewall, wherein the firewall has at least one opening, wherein the housing projects through the opening, wherein the housing has at least a first housing part and at least a second housing part, wherein the first housing part rests against the firewall with a seal interposed and is attached to the firewall, wherein a portion of the first housing part projects through the opening, and the second housing part is attached in a sealed manner to the portion of the first housing part that projects through the opening.

The present invention relates to a blower unit of an air conditioner for a vehicle, which can effectively prevent water from being introduced into a motor and has a motor housing and a blower wheel improved to smoothly perform cooling of the motor. The blower unit of a two-layered air conditioner for a vehicle, which can divide and inhale indoor air and outdoor air, includes: a scroll case having an upper passageway and a lower passageway; a first blower wheel disposed in the upper passageway; a second blower wheel disposed in the lower passageway and arranged below the first blower wheel; a blower motor for rotating the first blower wheel and the second blower wheel; and a motor housing for covering the blower motor, wherein a hub for guiding air is disposed on the second blower wheel, and the hub of the second blower wheel is partially overlapped with an end portion of the motor housing.

A roof top air conditioner unit for a vehicle, in particular a recreational vehicle, wherein the roof top air conditioner at least in part is made of expanded polypropylene (EPP). At least one stabilizing and/or connecting element of the roof top air conditioner unit is mold in the section of the roof top air conditioner unit made of EPP. Furthermore, the present invention refers to a method for producing, assembling and installing such roof top air conditioner units and a vehicle having such a roof top air conditioner assembly.

An HVAC system for a vehicle includes a housing, an evaporator disposed in the housing, and a heater disposed in the housing. The HVAC system further includes a bypass opening defined between an upper end of the evaporator and an upper end of the heater and an intermediate chamber defined by the evaporator, the heater, the housing, and the bypass opening. The HVAC system further includes an upper outlet passage configured to direct air from the HVAC system into a passenger compartment of a vehicle. The evaporator is configured to output a first stream of air into the intermediate chamber and the HVAC system is configured to operate in a first operating condition in which a first portion of the first stream of air will pass through the heater and a second portion of the first stream will bypass the heater by passing from the intermediate chamber through the bypass opening and into the upper outlet passage.
