Benefits of technology

The patent text describes a heat dissipation device for electronic components that uses a centrifugal fan and heat sink. The device is designed to be easily assembled and disassembled from a bracket. The technical effect of the invention is to provide a more convenient and efficient way of dissipating heat from electronic components.

Problems solved by technology

However, the previously mentioned assembling method requires screws and a screwdriver to perform these procedures.
As known by those skilled persons, the conventional method wastes time and manpower.

Embodiment Construction

[0013]Referring to FIG. 1, a heat dissipation device 100 in accordance with an embodiment of the disclosure is shown. The heat dissipation device 100 is used to thermally contact an electronic component (not shown) mounted on a printed circuit board (not shown) to dissipate heat generated by the electronic component. The heat dissipation device 100 includes a bracket 10, and a fan 20 and heat sink 30 mounted on the bracket 10.

[0014]Referring to FIG. 2, the bracket 10 includes a bottom plate 11 and two side plates 12 extending upwards from two opposite edges of the bottom plate 11. Each of the side plates 12 form an air guiding plate 13 extending inwards from inner sides thereof. The bottom plate 11 defines a rectangular window 15 and a circular opening 14 respectively at two sides of the air guiding plate 13. The bottom plate 11 forms two steps 151 extending downwards from opposite sides of the window 15. A plurality of projections 152 extend from bottoms of the side plates 12 and a...

Abstract

A heat dissipation device includes a bracket, a fan with an air inlet and an air outlet, and a heat sink mounted on the bracket. The bracket includes a plurality of rivets and clasps. Each of the clasps includes a mounting portion, an arm extending upwards from the mounting portion, and a hook portion extending from a top end of the arm and towards the mounting portion. The mounting portion is riveted on the bracket by a corresponding rivet. The fan includes a plurality of ears corresponding to the clasps. The hook portions of the clasps abut on top surfaces of the ears to fix the fan on the bracket. The fan defines a plurality of channels communicating the outlet of the fan.

Description

BACKGROUND[0001]1. Technical Field[0002]The disclosure relates to heat dissipation devices in electronics, and more particularly to a heat dissipation device with a centrifugal fan capable of being conveniently assembled to and disassembled from a bracket.[0003]2. Description of Related Art[0004]A heat sink is usually placed in thermal contact with a heat generating electronic device such as a central processing unit (CPU), and transfers heat through conduction away from the heat generating electronic device so as to prevent over-heating of the heat generating electronic device.[0005]Typically, a centrifugal fan is mounted on a side of a heat sink to improve heat dissipation efficiency of the heat sink. In a conventional assembling method, the fan is locked onto the heat sink by screws interferentially engaged with fins of the heat sink. However, the previously mentioned assembling method requires screws and a screwdriver to perform these procedures. As known by those skilled person...
