Abstract
A radiator includes a flat base (10), a pair of heat pipes (20) and a plurality of fins (30) on the base. The base defines a pair of grooves (12) through a top portion thereof. Each heat pipe includes parallel and symmetrical first and second sections (22, 24). The first sections are soldered to the base in the grooves. Each fin defines a notch (32) at a bottom portion thereof and a pair of holes (36) at opposite sides of the notch. Flanges (35) extend perpendicularly from the notches of the fins, cooperatively defining a streamline airflow guiding surface. Collars (37) extend perpendicularly from the holes of the fins, for receiving the second sections of the heat pipes.
Claims13
A radiator comprising:
- a flat base;
- a fin assembly having a top portion adapted for mounting a fan thereon, and a bottom portion mounted on the base, an airflow guiding surface defined from the bottom portion toward the top portion, the airflow guiding surface having a peak distant from the bottom portion and two parts extending from the peak toward two opposite sides of the bottom portion in a slant manner, respectively, whereby an airflow generated by the fan flows along the two parts of the airflow guiding surface via the peak thereof toward the two opposite sides of the bottom portion;
- and
- a heat pipe comprising a first section lodged in the base and an opposite second section extending through the fin assembly.
A radiator comprising:
- a base defining a flat bottom surface adapted to contact a heat generating device, a fan being located adjacent to said fin assembly;
- and
- a fin assembly positioned on the base, including a plurality of parallel spaced fins, each of said fins being equipped with a flange defining an airflow guiding surface toward the base, wherein
- each of said fins defines a space under said flange and above said base for ventilation in a direction perpendicular to said fins, an airflow driven by said fan not entering said space due to said flange;
- wherein a notch is defined in the each fin facing the base, and the flange is formed along a border of the notch so as to define the airflow guiding surface;
- and
- wherein the airflow guiding surface comprises a pair of continuous cambered surfaces encountering with each other at their uppermost points.
