A centrifugal fan includes a housing and an impeller rotatably received in the housing. The housing defines an air inlet in a top plate thereof and an air outlet in a sidewall thereof. The air inlet is perpendicular to the air outlet. The impeller includes a hub and a plurality of blades extending outwardly from a sidewall of the hub. Each of the blades includes an inner blade section connected with the sidewall of the hub and an outer blade section extending outwardly from the inner blade section. An upper portion of the inner blade section is curved upwardly and forwardly from a curved lower portion of the inner blade section towards an adjacent front blade. The curved lower portion has a curvature smaller than that of the upper portion.

Thermal module

An electronic device includes a first electronic component, a second electronic component adjacent to the first electronic component, a heat sink arranged on the first electronic component to absorb heat therefrom, an axial fan mounted on the heat sink for generating an airflow to the heat sink, and a guiding member. The axial fan includes a frame and an impeller received in the frame. A cutout is defined in the frame facing the second electronic component. The guiding member is arranged between the axial fan and the second electronic component for guiding a part of the airflow escaping from the frame via the cutout to the second electronic component.

Heat dissipation module

A heat dissipation apparatus includes a heat sink () and a fan () mounted on the heat sink. The heat sink includes a plurality of radial fins (). An air channel () is defined between every two adjacent fins. Each of the fins includes a main body () and an airflow guiding flange () extending upwardly and outwardly from a top side of the main body. The airflow guiding flange is twisted in a radial direction, such that an included angle between the airflow guiding flange and the main body is gradually increased from an outer side () towards an inner side () of the main body. The fan is used to generate airflow towards the heat sink. The airflow is guided into the air channels between the fins via the airflow guiding flanges.
