Description
BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention is related to a heat-radiator for a CPU, and more particularly to a fastener for a heat-radiator.

[0003] 2. Description of Related Art

[0004] CPU is the most important component in a computer and will generate a lot of heat in operating. A heat-radiator must be installed on the CPU for lowering the temperature of the operating CPU. Most computers use PentiumŪ III or PentiumŪ 4 processors made by Intel Corporation as CPUs. For PentiumŪ III processors, the heat-radiators are directly fastened on sockets on which the processors are installed. For PentiumŪ 4 processors, Intel Corporation has presented a standard radiator seat, whereby, the heat-radiators for PentiumŪ 4 processors are installed on the seat. Thus, the fasteners for installing the heat-radiators for PentiumŪ III or PentiumŪ 4 processors are different. When a user wants to replace a PentiumŪ III processor with a PentiumŪ 4 processors, the heat-radiator with fasteners specially designed for the processor seat must be used, which increases the user's outlay.

[0005] Therefore, the invention provides a fastener for a heat-radiator to mitigate and/or obviate the aforementioned problems.

SUMMARY OF THE INVENTION

[0006] The main objective of the invention is to provide a fastener which can used for installing a heat-radiator on a PentiumŪ III or a PentiumŪ 4 processor.

[0007] Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0015] Referring to FIGS. 1-4, in accordance with a first embodiment of the invention, a fasten is composed of a frame (10) and two first strips (20). The frame (10) has two parallel long sides (11) and two parallel short sides (not numbered) perpendicular to the long sides (11). Each of the long sides (11), of which a section is V-like, has a bottom part and two bevel parts respectively extending outwards and upwards from two ends of the bottom part. Each of the short sides has at least one aperture (12) defined therethrough. In this embodiment, two first apertures (12) are defined through each short side.

[0016] Each of the first strips (20) has at least one first ear (21) to correspond the aperture (12). Two barbs (22) are respectively formed at two ends of the first strip (20) and perpendicular to the first strip (20). The first ear (21) has two legs (210) and a notch (211) defined between the legs (210). A size between outer sides of the legs (210) is larger than a maximum diameter of the aperture (12). When the ear (21) is inserted in the aperture (12), the legs (210) can be compressed towards the notch (211) to reduce the size between the outer sides of the legs (210) for passing through the aperture (12). Thereafter, the legs (210) can recover the original size and is secured in the aperture (12).

[0017] The first embodiment of the fastener is used for installing a heat-radiator (32) on a seat (31) outside a PentiumŪ 4 processor (30). The strips (20) are first mounted on the short sides of the frame (10) by inserting ears (21) in the respective apertures (12). The long sides (11) are positioned in fins (not numbered) of the heat-radiator (32). The barbs (22) on the strips (20) are respectively attached in holes (310) of the seat (31) and the heat-radiator (32) is tightly secured on the seat (31).

[0018] Referring to FIGS. 5-7, in a second embodiment of the invention, the fastener has a frame (40) and two second strips (50). The frame (40) the same as that of the first embodiment of the invention, has two parallel long sides (41) and two parallel short sides (not numbered) perpendicular to the long sides (41). Each of the long sides (41), of which a section is V-like, has a bottom part and two bevel parts respectively extending outwards and upwards from two ends of the bottom part. Each of the short sides has at least one aperture (42) defined therethrough. In this embodiment, two first apertures (42) are defined through each short side.

[0019] Each of the second strips (20) has at least one first ear (51) to correspond the aperture (42). A U-like plate (not numbered) is formed on the second strip (20) and perpendicular to the second strip (20). A plurality of windows (52) is defined through the U-like plate.

[0020] Similar to the first ear (21), the second ear (51) also has two legs and a notch defined between the legs. When the second ear (51) is inserted in the aperture (42), the legs can be compressed towards the notch for passing through the aperture (42). Thereafter, the legs can recover the original size and is secured in the aperture (12).

[0021] The second embodiment of the fastener is used for installing a heat-radiator (62) on a socket (61) for a PentiumŪ III processor (60). The strips (50) are first mounted on the short sides of the frame (40) by inserting second ears (51) in the respective apertures (42). The long sides (41) are positioned in fins (not numbered) of the heat-radiator (62). Protrusions (610) on side surfaces of the socket (61) are respectively engaged in the windows (52) of the strip (50), so that the heat-radiator (62) is tightly secured on the socket(61).

[0022] According to the present invention, when a user wants to replace a PentiumŪ III processor with a PentiumŪ 4 processor, the former heat-radiator can be used by changing the strips of the fasteners. Thus, the outlay of the user is low.

[0023] It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
