Abstract
As a result of the stringent noise regulations for heavy-duty vehicles, the use of shields and enclosures for engine compartment has been increasingly applied, but it is difficult for a conventional axial flow fan to provide the required airflow against higher resistance caused by such shields and enclosures.
To solve this problem, a new, mixed flow fan (hereafter called MF fan) which is suitable for the higher resistance has been developed and this paper describes the development process of the MF fan.
The design criteria of the MF fan were experimentally investigated with a test rig, and an optimum combination of design parameters were established. The airflow was improved approximately 6 % without any additional power loss in comparison with the conventional axial flow fan.
