The present invention relates to a fluid line system (10) for guiding fluid, in particular for a motor vehicle. The fluid line system (10) comprises a sensor device (20) for capturing sensor parameters and a housing (30), which has two or more housing parts (40, 60). Each housing part (40, 60) has a mounting surface area (50, 70) for arranging a further housing part (40, 60). The housing (30) further has a groove arrangement (80), which comprises at least one groove recess (90), which is arranged on a mounting surface area (50, 70), wherein a groove recess (90) has a groove opening (95), which opens out to the respective mounting surface area (50, 70). In any case, the groove opening (95) is closed by in a fluid-tight manner means of the mounting surface area (50, 70) of at least one further housing part (40, 60). It is attained thereby that a fluid duct (99), through which fluid can flow and through which fluid can be applied to the sensor device (20), is limited between the respective groove recess (90) and the respective mounting surface area (50, 70).

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 method for servicing a heater core installed in a heating, ventilation, and air-conditioning (HVAC) assembly for a motor vehicle includes removing a sealing attachment from an interfacing connection interfacing with the heater core. The method includes sliding the heater core in a direction of insertion. The method includes disconnecting, from the heater core, the interfacing connection. The method includes removing the heater core in a direction of extraction, the direction of extraction being orthogonal to the direction of insertion.

A blow molded part is provided that includes a first portion consisting of a reinforced resin and a second portion consisting of a non-reinforced resin. The reinforced resin may be fiber-reinforced, and the non-reinforced resin may be a neat resin. In one form, the first portion and the second portion define first and second trim areas, respectively, and the second trim area is directly recyclable. In another form, the second portion comprises a material consisting of a non-reinforced resin and/or a reinforced resin, where the modulus of elasticity of the first portion is higher than the modulus of elasticity of the second portion. Furthermore, a method of forming a blow molded part is provided.

For example, an apparatus may include an input to receive input information including a Heating, Ventilation and Air Conditioning (HVAC) input including HVAC configuration information corresponding to a configuration of an operation of an HVAC system of a vehicle; a plurality of noise inputs representing acoustic noise at a plurality of noise sensing locations; and a plurality of residual-noise inputs representing acoustic residual-noise at a plurality of residual-noise sensing locations within at least one sound control zone in the vehicle; a controller configured to determine a sound control pattern to control sound within the at least one sound control zone in the vehicle, the controller configured to determine the sound control pattern based on the HVAC input, the plurality of noise inputs and the plurality of residual-noise inputs; and an output to output the sound control pattern to a plurality of acoustic transducers.

An airflow turning device with airflow control channels for an outlet of a heating, ventilation, and air conditioning (HVAC) case that directs airflow to a plurality of different vehicle outlets. The airflow control channels extend from an inner upstream side of the outlet to an outer downstream side of the outlet. Different ones of the plurality of channels have different lengths to generate a varied pressure drop at the outer downstream side in response to airflow blown into the plurality of channels from the inner upstream side.
