A heat sink ( ) includes a circular base ( ), a plurality of fins ( ), and a central post ( ). The base is adapted to be in thermal contact with an electronic device, to remove heat therefrom. The post extends from a top surface ( ) of the base. The post has a first surface connected to the top surface and a second surface ( ) dimensioned according to a heat sink fan to be attached thereon. The post also has a concave side surface ( ) between the second surface of the post and the top surface of the base, for directing airflow. The fins are identical in height to the post. The fins are curved, aligned and spaced from each other at uniform intervals corresponding to directions of airflow generated from the fan. These minimize resistance to cooling air entering or exiting the heat sink.

Turbinate heat sink

A heat removal system includes a heat dissipation assembly ( ) and a system fan ( ) which cooperatively achieve optimized heat dissipation efficiency. The heat dissipation assembly includes a heat sink ( ) and an angled fan ( ). The heat sink includes a base ( ) and a plurality of parallel fins ( ). A slanted surface ( ) is defined by a set of adjacent edges of the fins. The fan defines a through hole ( ) at each of four corners thereof. Four screws ( ) extend through the through holes, thus attaching the fan to the heat sink at the slanted surface. A rotational axis of the fan intersects a central portion of the base of the heat sink, which portion defines a region of highest temperature of the heat sink. The angled fan together with the system fan provide maximized cooling airflow.

Heat removal system

A heat sink clip ( ) includes a body ( ), and first and second arms ( ) depending from opposite ends of the body. The body includes a curved portion ( ), first and second spring portions ( ) extending from opposite ends of the curved portion, and a connecting portion ( ) between the second spring portion and the second arm. Each arm defines aperture ( ). A fin ( ) with a hole ( ) defined therein is stamped outwardly from the second arm above the aperture, for engaging with a tool. Two flanges ( ) extend upwardly from respective opposite longitudinal edges of the curved portion, thereby reinforcing the curved portion. Two longitudinal ribs ( ) are formed at respective opposite sides of the curved portion, thereby reinforcing the body.

Heat sink clip

A heat sink assembly includes a heat sink (,), a fan (,), and a fixing device (,). The heat sink has a chassis (,) which defines a pair of diagonally opposite grooves (,) in respective opposite side walls thereof. The fan defines a vertical through hole (,) at each comer. The fixing device has a rectangular base (,). A pole (,) having a barb (,) extends upwardly from each comer of the base, for engaging with the corresponding through hole. A pair of legs (,) depends from each side of the base. A catch (,) is formed at a distal end of each leg, for engaging with the heat sink. Two guard boards (,) depend from each side of the base. A pair of bosses (,) is formed at distal ends of two diagonally opposite guard boards, for engaging with the grooves of the heat sink.
