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.

The present invention relates to a balance structure of a fan wheel, which comprises a hub and a plurality of blades disposed on the circumferential side of the hub. The hub has a top wall connected to a sidewall. An unbalanced portion for being removed is selectively disposed on the top wall or on the sidewall. The unbalanced portion is disposed on one side of a symmetrical axis of the hub. In this way, the weight of the fan wheel is balanced.

Balance structure of fan wheel

A fan structure includes a frame body and a fan impeller. The frame body has a base seat and an annular wall. A bearing cup upward extends from a center of the base seat. At least one groove is annularly formed on inner wall face of the annular wall. The fan impeller is pivotally disposed in the bearing cup and has a hub and multiple blades outward extending from the hub. Each blade has an end edge. At least one protrusion section outward protrudes from the end edge into the groove. According to the design of the fan structure, the protrusion section can destroy the production of the vortex of the blade of the conventional fan so as to greatly minify the strength of the vortex. Therefore, the structure of the sound field of the vortex is changed so that the noise of the fan structure is lowered.

The present invention relates to a balance structure of a fan rotor, which comprises a fan wheel and a balancing part. The fan wheel has a hub and a plurality of blades disposed on the circumferential side of the hub. The hub has a top wall connected to a sidewall. An unbalanced portion is selectively disposed on the top wall or on the sidewall. The unbalanced portion is disposed on one side of a symmetrical axis of the hub. The balancing part is disposed at the unbalanced portion such that the fan rotor is balanced.
