摘要： An axial fan frame with electrical connection structure includes a frame and a circuit board. The frame includes a shaft holder having a receiving recess located near an air outlet of the frame for receiving the circuit board therein, a plurality of stator blades connected to between the shaft holder and the frame, a groove formed on an outer surface of the frame for receiving an external cord assembly therein, and a communicating passage located between the receiving recess of the shaft holder and the groove of the frame to communicate them with each other. The circuit board has an outward extended arm, which has a metal contact end for connecting to an electrical connector provided at an end of the external cord assembly. Therefore, the external cord assembly can be quickly electrically connected to the circuit board in an automated manner without the need of welding manually.

摘要： An apparatus and methods are provided for a portable mass airflow (MAF) training module configured to simulate an air intake into an internal combustion engine. An in-line blower draws an airflow through an air filter by way of a first air duct and a second air duct. A throttle assembly is coupled between the first air duct and the second air duct. The throttle assembly includes a throttle plate that may be rotated to regulate the airflow. The power output of the in-line blower is variable to simulate the air intake of various sizes of the internal combustion engine. A MAF sensor and a duct velocity sensor are configured to provide airflow information. The portable MAF training module enables a practitioner to select a desired throttle setting and observe a resultant mass airflow through the portable MAF training module that is measured by the MAF sensor.

摘要： A combination structure of a fan guard and static blades is disclosed. The fan guard includes an annular plate, multiple radial ribs, and multiple circumferential ribs. The annular plate is fixed on a motor base. The radial ribs arranged around the annular plate extend radially. The circumferential ribs are arranged concentrically and spacedly and connected with radial ribs in series. Each of the static blades includes a blade body, an inner and an outer coupling plate. The inner coupling plate and the outer coupling plate are arranged on two ends of the blade body respectively. The blade body is fixed on one side of the fan guard through the inner coupling plate being combined with one end of the radial rib and through the outer coupling plate being combined with another end of the radial rib to make the static blades be combined on the fan guard.

摘要： A fan assembly includes axial fans, a connector, a chassis portion, and a first vibration-proof portion. The axial fans are arranged in a first direction intersecting the rotation axis extending in the axial direction. The connector is closer to one side of the first direction with respect to the axial fans, and electrically connects the axial fans and an external device. The chassis portion accommodates the axial fans and the connector. The first vibration-proof portion is located on an outer surface of an end portion on the one side in the first direction of the chassis portion, and protrudes outward.
