摘要： A heat dissipation system with air sensation function includes a chassis, multiple fans, multiple air sensation units and an external control device connected to the fans. The chassis has an installation face for installing the fans thereon. The air sensation units are respectively disposed on the fans for detecting the air state of the corresponding fans to generate an air sensation signal. The external control device serves to receive the air sensation signal transmitted from the air sensation units and compare the data contained in the air sensation signal with preset data so as to control/adjust the rotational speed of the corresponding fans. Accordingly, a uniform airflow flows out of the fans to effectively lower the noise.

摘要： A fan active noise self-lowering system includes a fan, a push assembly, at least one pickup unit and a digital signal processing unit. The pickup unit serves to capture the noise made by the fan to generate a noise input signal and transmit the noise input signal to the digital signal processing unit. The digital signal processing unit receives the noise input signal and processes the noise input signal to output a control signal for controlling the push winding assembly to operate so as to push the fan impeller of the fan to move up and down. Accordingly, the fan impeller will generate a reverse sonic wave to offset the noise.

摘要： A laser-welded joint structure between insulation frame and bearing cup of fan includes a base having a bearing cup and a stator having at least one insulation frame. The insulation frame includes a sleeve portion defining a bore axially extending therethrough. The sleeve portion is provided on an inner wall surface with at least one pressing section that radially projects into the bore to press a lower side against an upper end of the bearing cup and a bearing received therein. A portion of at least one lateral side of each pressing section that is in contact with the upper end of the bearing cup is melted by laser beam to form a laser-welded joint, so that the insulation frame and the bearing cup are integrally connected together at reduced manufacturing cost and have increased structural strength. A method of forming the laser-welded joint structure is also disclosed.
