Title:
VEHICLE AIR-CONDITIONING UNIT
Document Type and Number:
WIPO Patent Application WO/2019/021707
Kind Code:
A1
Abstract:
This vehicle air-conditioning unit comprises: an air-conditioning case (12) wherein is formed an in-case passage (123) through which air flows; a blower (20); and an airflow rectifier (16, 26, 28). The blower has a blower fan (201) which rotates about a fan axis (CL1) and is disposed in the in-case passage, and air pulled from one side in the axial direction (DRa) of the fan axis is pushed by means of the rotation of the blower fan. The airflow rectifier is disposed in the in-case passage downstream of the airflow with respect to the blower fan, and air pushed by the blower fan passes through the airflow rectifier. The blower fan is disposed in such orientation that the other side along the fan axis, which is opposite of said one side in the axial direction, extends toward the downstream end of the airflow in the in-case passage. The airflow rectifier mitigates swirling flow generated by the rotation of the blower fan in the air pushed by the blower fan, in contrast to the state of the pushed air prior to flowing into the airflow rectifier.
