1. Technical Field
The present disclosure relates to electronic devices, and particularly to an electronic device with a quickly-detachable heat sink.
2. Description of Related Art
Circuit boards, such as motherboards, are located in an enclosure of a server or a computer. A CPU may be located on the circuit board. A heat sink is installed on the circuit board for dissipating heat generated by the CPU. The heat sink abuts the CPU and is secured to the circuit board by a plurality of screws. However, assembly or disassembly of the heat sink is very time-consuming and inconvenient.
Therefore, there is room for improvement within the art.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”
A heat generating part 11, such as CPU, is located on the circuit board 10. The circuit board 10 defines two through holes 13 located on opposite sides of the heat generating part 11. Each of the two through holes 13 includes a wide portion 131 and a narrow portion 133 in communication with the wide portion 131. A width of the wide portion 131 is greater than a width of the narrow portion 133.
The heat sink 30 includes a main body 31 and two resilient pieces 33. The two resilient pieces 33 are located on diagonally opposite corners of the main body 31. The main body 31 is to collect and dissipate heat generated by the heat generating part 11.
Each of the two resilient pieces 33 includes a latching portion 331 and a resisting portion 333 located on the latching portion 331. The latching portion 331 includes a resilient arm 3311, an engaging portion 3313, and a connecting portion 3315 connected to the resilient arm 3311 and the engaging portion 3313. The resilient arm 3311 extends from the main body 31. The connecting portion 3315 extends from the resilient arm 3311. The engaging portion 3313 extends from the connecting portion 3315. The resisting portion 333 extends upwards from a distal end of the engaging portion 3313. A width of the engaging portion 3313 is smaller than the width of the wide portion 131 and greater than the width of the narrow portion 133. A width of the resisting portion 333 is smaller than the width of the narrow portion 133. The connecting portion 3315 is substantially perpendicular to the resilient arm 3311. An acute angle is defined between the connecting portion 3315 and the engaging portion 3313.
