1. Technical Field
The present disclosure relates to electronic devices, and particularly to an electronic device with a cooler.
2. Description of Related Art
A cooling device is often used to cool a heat generating component, such as a central processing unit (CPU). The heat generating component is often secured to a mounting member. Generally, the cooling device comprises a cooler and a backboard for securing the cooler to a circuit board. Each of the cooling devices made from different manufacturers may each have a different specification and a different mounting method. As a result, each of the cooling devices may has a different backboard corresponding to every different mounting member When the mounting member is to be replaced, the backboard of the cooling device corresponding to the mounting member may also need be replaced. Replacing the backboard may be costly and time consuming. An improved electronic device with a cooling device may be desired.
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.
Referring to
The cooler 10 comprises a plurality of fins 11, and a plurality of mounting portions 13 in the plurality of fins 11. Each of the plurality of mounting portions 13 comprises a first mounting piece 131, and a second mounting piece 133 adjacent to the first mounting piece 131. The first mounting piece 131 and the second mounting piece 133 extend from adjacent two of the plurality of fins 11. The first mounting piece 131 defines a first mounting hole (not shown), and the second mounting piece 133 defines a second mounting hole 1331. A first locking member 100, such as a screw, is inserted into each first mounting hole. A spring 300 is secured between a top end of the first locking member 100 and a top end of the first mounting piece 131. A shape, outlined by the first mounting pieces 131, is substantially a rectangle, and each first mounting piece 131 is at a corner of the rectangle. In one embodiment, the plurality of fins 11 defines a round outline, and the round outline is located in the rectangle.
The fan assembly 30 comprises a case 31, and a fan (not labeled) secured to the case 31. Each corner of the case 31 defines a through hole 311 corresponding to each of the second mounting hole 1331 of the second mounting piece 133.
The backboard 50 comprises a body 51, and a positioning pieces 53 extending from each corner of the body 51. The body 51 defines an opening 515, and a plurality of first positioning holes 511 on two opposite sides of the opening 515. Each of the positioning pieces 53 defines a second positioning hole 531. A distance between adjacent two of the second positioning holes 531 is substantially equal to a distance between adjacent two of the first mounting holes of the first mounting piece 131. A first polygon is outlined by the plurality of first positioning holes 511. A second polygon is outlined by the second positioning holes 531. In one embodiment, the first polygon is located in the second polygon.
The circuit board 105 defines a plurality of first securing holes 1051, and a plurality of second securing holes 1053. Each of the plurality of first securing holes 1051 corresponds to each of the plurality of first positioning holes 511. Each of the plurality of second securing holes 1053 corresponds to each of the second positioning holes 531. In one embodiment, the circuit board 105 is a motherboard.
Referring to
The first mounting member 70 and the second mounting member 73 are adapted to connect the heat generating component 80 to the circuit board 105. The first mounting member 70 defines a plurality of locking holes 71 corresponding to the plurality of first positioning holes 511 of the backboard 50.
In assembly, the fan assembly 30 is placed above the cooler 10. The fan assembly 30 abuts the cooler 10, and the through holes 311 are aligned with the second mounting holes 1331 of the cooler 10. A locking member, such as a screw, is inserted through each of the through holes 311 and the second mounting holes 1331. The fan assembly 30 is secured to the cooler 10.
