  • Patent number: 10537041
    Abstract: 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.

  • Patent number: 10180145
    Abstract: A fan salt-fog-resistant structure and a fan frame thereof. The fan salt-fog-resistant structure includes a base seat having a bearing cup and at least one flow guide body. Multiple connection bodies outward extend from the base seat. The flow guide body is disposed at a junction between the base seat and the connection bodies. The fan frame includes a main body having a first open side and a second open side and a flow passage defined therebetween. One end of the connection body is connected with the second open side. When airflow entraining moisture and salt fog flows through the junction between the base seat and the connection bodies, the flow guide body serves to guide the airflow and prevent the airflow from forming eddy, whereby the salt fog entrained by the airflow will not crystallize to form sediments at the junction between the base seat and the connection bodies.

  • Publication number: 20180306207
    Abstract: 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.
