摘要

Automotive vehicles use aspirators to sense in-car temperature for controlling thermal comfort. The aspirator noise at the sensor end located on dash can be unacceptable and therefore an additional muffler is used between the sensor and the aspirator. An innovative aspirator design was developed to replace the aspirator and muffler by a one-piece design. This new concept was designed to meet the noise performance targets while making it easy to manufacture, while meeting the airflow targets of the current production two-part aspirator and muffler design. The new design incorporates the change in airflow direction to address the customer concern.
