Embodiment Construction

[0068] In these figures, the same elements have the same reference numerals.

[0069] figure 1 A cross-section of a heater unit 1 is shown, which is intended to be fitted to a motor vehicle in order to adjust the aerothermal parameters of the air flow distributed to one or more regions inside the vehicle.

[0070] The heater unit 1 comprises a housing 3 delimiting an internal volume defining a channel through which an air flow circulates.

[0071] The heater unit 1 comprises a motor-fan unit, also called a blower 5 , for introducing air into the housing 3 of the heater unit 1 . An air filter 6 may be arranged upstream of the fan 5 in the direction of the air flow flowing through the housing 3 .

[0072] The housing 3 comprises at least one inlet 7 for admitting a flow of external air from outside the vehicle so it can circulate through the internal volume delimited by the housing, and / or for admitting a flow of recirculated air from the interior of the vehicle, and The flow...

Abstract

The invention concerns a grid (14) for homogenising an air stream for a heating apparatus for a motor vehicle comprising an electric heating device, said grid comprising: - a first area (Z1) having at least one first opening (29) intended to be arranged upstream from at least one heat sink in the direction of flow of said air stream, said at least one heat sink being arranged on one side of said heating device, and - a second area (Z2) separated from the first area (Z1) and having a plurality of second openings (31) intended to be arranged upstream from at least one heating element of said heating device in the direction of flow of said air stream. The invention also concerns a heating apparatus comprising: - an electrical heating device comprising: at least one heating element, an electronic control unit, and at least one heat sink arranged on one side of said heating device, and - such a homogenizing grid (14) arranged upstream from said heating device in the direction of flow of said air stream.

Description

technical field [0001] The invention relates to a grille for homogenizing air flow for a heater unit for the interior of a motor vehicle which allows temperature control of the air flow in one or more regions of the interior of the motor vehicle. Background technique [0002] Motor vehicles are usually equipped with heater units intended to adjust the aerothermal parameters of the air distributed into the vehicle interior, in particular the temperature of the air flow delivered by the unit into the vehicle interior. [0003] In general, the unit comprises a housing delimited by partitions through which openings are formed, the openings comprising at least one air inlet and at least one air outlet. [0004] In a known manner, the housing generally houses a motor / fan unit, also called a fan, for circulating an air flow from the air inlet to the air distribution outlet. [0005] The housing also houses heat treatment means, in particular for warming up the air flow before bein...
