1. Technical Field
The present disclosure generally relates to fastening mechanisms, and particularly to a fastening mechanism for fixing a radiator.
2. Description of the Related Art
Electrical components, such as a CPU of a computer, generate a great deal of heat. Excessive heat can affect the performance of the CPU or damage the CPU. A radiator is usually fixed on the CPU via a fastening mechanism to cool the CPU. However, the current fastening mechanism has a complex structure and is difficult to operate.
Therefore, there is room for improvement within the art.
The components in the drawings are not necessarily drawn to scale, the emphasis instead placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.

The fastening mechanism 40 includes two fixing rods 41 positioned near opposite sides of the conducting base 31, and a fastening assembly 42 positioned between the heat sinks 32. Each fixing rod 41 includes a main body 410, a fixing end 411, and a restricting end 412. The fixing end 411 and the restricting end 412 are positioned on opposite ends of the main body 410. The fixing end 411 is fixed to the circuit board 10.
The fastening assembly 42 includes a connecting member 421 and two fastening arms 422 connected to the connecting member 421. The connecting member 421 includes two positioning arms 4211 substantially parallel to each other, and two connecting poles 4212 connecting the positioning arms 4211. Each positioning arm 4211 is substantially U-shaped, and includes a first section 4211a and two second sections 4211b extending substantially perpendicularly from opposite ends of the first section 4211a. A length of the second sections 4211b is larger than a height of the heat sinks 32 relative to the circuit board 10. Each connecting pole 4212 is connected to the second sections 4211b of the positioning arms 4211, and is substantially perpendicular to the positioning arm 4211. Two arc-shaped receiving portions 4212a are formed on each positioning arm 4211. In an alternative embodiment, the positioning arm 4211 may have three or more receiving portions 4212a.
Each fastening arm 422 is substantially U-shaped, and forms a connecting portion 4221 at a first end, and two hook portions 4222 at a second end opposite to the first end. In the illustrated embodiment, the connecting portion 4221 is arc-shaped, and restricting end 412 is hemispherical. A radius of the connecting portion 4221 is less than that of the restricting end 412 and greater than a radius of the main body 410, so that the connecting portion 4221 can sleeve on the main body 410 and resist the restricting end 412. The hook portions 4222 engage with the receiving portions 4212a of the connecting member 421, thereby rotatably connecting the fastening arm 422 to the connecting member 421. In alternative embodiments, the hook portions 4222 can be fixed to the receiving portions 4212a, and the fastening arm 422 and the connecting member 421 can be integrally formed.
