Abstract

L'invention a pour objet un dispositif de climatisation de véhicule automobile, notamment un HVAC, comportant une cavité comprenant une chicane acoustique à l'intérieur d'un canal de refroidissement, réalisée par au moins une nervure, notamment des nervures, de préférence avec le même matériau que l'unité HVAC pour éviter des surcoûtsThe subject of the invention is an air-conditioning device for a motor vehicle, in particular an HVAC, comprising a cavity comprising an acoustic baffle inside a cooling channel, made by at least one rib, in particular ribs, preferably with the same material as the HVAC unit to avoid extra costs

Description

L’invention est applicable dans toute cavité, notamment de HVAC, présentant un problème acoustique dû aux dimensions de la cavité. Dans l'application de ventilation automobile, la cavité est excitée par la vitesse de l'air proche de la cavité.The invention is applicable in any cavity, in particular HVAC, presenting an acoustic problem due to the dimensions of the cavity. In automotive ventilation applications, the cavity is excited by the speed of the air near the cavity.

L'état de la technique consiste à éviter de capter le flux d'air à 90 ° par rapport à la direction de la vitesse de l'air. En effet, il crée une turbulence d'écoulement d'air qui génère du bruit dans la cavité.The state of the art consists in avoiding capturing the air flow at 90 ° relative to the direction of the air speed. Indeed, it creates an air flow turbulence which generates noise in the cavity.

Une autre solution consiste à mettre en œuvre une mousse acoustique à l'intérieur de la cavité pour absorber le bruit généré dans la cavité.Another solution is to use an acoustic foam inside the cavity to absorb the noise generated in the cavity.

L'invention concerne ainsi un dispositif de climatisation de véhicule automobile, notamment un HVAC, comportant une cavité comprenant une chicane acoustique à l'intérieur d’un canal de refroidissement, réalisée par au moins une nervure, notamment des nervures, de préférence avec le même matériau que l'unité HVAC pour éviter des surcoûts. Ce ou ces nervures, de préférence formant une ou plusieurs baggles, sont agencées pour éviter la création d’ondes acoustiques stationnaires entre des parois de la cavité.The invention thus relates to a motor vehicle air conditioning device, in particular an HVAC, comprising a cavity comprising an acoustic baffle inside a cooling channel, produced by at least one rib, in particular ribs, preferably with the same material as the HVAC unit to avoid additional costs. This or these ribs, preferably forming one or more baggles, are arranged to avoid the creation of standing acoustic waves between walls of the cavity.

Selon un exemple de l’invention, le ou ces nervures sont agencées pour limiter les effets secondaires tels que l'augmentation de la chute de pression et la réduction du débit d'air afin d'assurer le refroidissement du moteur.According to an example of the invention, the rib or ribs are arranged to limit the side effects such as the increase in the pressure drop and the reduction in the air flow in order to cool the engine.

Dans une application HVAC centrée, le canal de refroidissement est mis en œuvre dans une partie supplémentaire au-dessus d’un évaporateur. Un problème de bruit apparaît autour de 2100Hz quel que soit le débit d'air (en raison des dimensions de la cavité).In a centered HVAC application, the cooling channel is implemented in an additional part above an evaporator. A noise problem appears around 2100Hz whatever the air flow (due to the dimensions of the cavity).

Les positions du ou des nervures évitent l'onde stationnaire acoustique créée par la réflexion du bruit entre deux parois de la cavité et assurent une section de chemin d'air suffisante pour fournir le débit d'air au moteur électrique pour le refroidir.The positions of the rib (s) avoid the standing acoustic wave created by the reflection of noise between two walls of the cavity and provide an air path section sufficient to supply the air flow to the electric motor to cool it.

La dimension des nervures est choisie fonction des dimensions de la cavité:The dimension of the ribs is chosen according to the dimensions of the cavity:

- de préférence la hauteur des nervures est aussi proche que possible de la hauteur de la cavité- preferably the height of the ribs is as close as possible to the height of the cavity

- de préférence la taille et la position des nervures sont implémentées pour avoir une superposition- preferably the size and position of the ribs are implemented to have a superposition

- de préférence la section du flux d'air ne doit pas être réduite pour limiter l'augmentation de la perte de charge et assurer le refroidissement du moteur.- preferably the section of the air flow should not be reduced to limit the increase in pressure drop and ensure the cooling of the engine.
