1. Field of the Invention
The present invention relates to an improved structure for a backup fan and, more particularly, to an improved structure for a backup fan which is easily assemble, change and disassemble.
2. Description of the Related Art
Due to the high operational speeds of computer chips, it is important to provide a good heat removal system; otherwise the operational speeds of the computer chips may slow down, or the chips can even burn out. As shown in
Therefore, it is desirable to provide an improved structure for a backup fan to mitigate and/or obviate the aforementioned problems.
SUMMARY OF THE INVENTIONA main objective of the present invention is to provide an improved structure for a backup fan, which is easy to assemble, change and disassemble.
In order to achieve the above-mentioned objective, the improved structure for a backup fan of the present invention comprises a containment case comprising a top opening and at least one containment space, each containment space has a front-side ventilation opening and a back-side ventilation opening; at least one first fan capable of being positioned in the containment space of the containment case through the top opening of the containment case; at least one second fan capable of being positioned in the containment space of the containment case through the top opening of the containment case, the second fan and the first fan placed tightly next to each other; and a top cover for covering the top opening of the containment case.
Furthermore, the containment case further comprises a slot and a stay ring, the top cover comprising a pin and a fastening plug, the pin of the top cover capable of inserting into the slot of the containment case, and the fastening plug of the top cover capable of being fastened in the stay ring of the containment case. Moreover, there is a containment space, a first fan and a second fan, or alternatively, there are two containment spaces, two first fans and two second fans.
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.
BRIEF DESCRIPTION OF THE DRAWINGS
The First Embodiment:
Please refer to
In order to install the backup fan in the case, the first fans 20, 21 and the second fans 30, 31 are first respectively placed in the containment spaces 12, 13 of the containment case 10, as shown in
When the first fans 20, 21 or the second fans 30, 31 become broken and need to be replaced, the case 100 first must be opened, and then the fastening plug 42 of the top cover 10 is loosened from the stay ring 15 of the containment case 10 and the pin 41 of the top cover 40 is removed from the slot 14 of the containment case 10 so that the top cover 40 and the containment case 10 are separated. A user can take out the broken fans and install new fans as described in the above steps.
The Second Embodiment:
In this embodiment, both the structure and installation process are similar to the first embodiment; the only difference is that the second embodiment only contains one first fan 200 and one second fan 300.
The advantage of the present invention is that no screws are needed for installing, and so when the user notices that the fan is broken, he or she can disassemble the fan without requiring any tools. Furthermore, the present invention requires only a small space; regardless of how many fans are installed, only one containment case is required, instead of requiring a containment case for each individual fan as in the prior art. Moreover, the structure of the present invention can be extended to accommodate additional fans to satisfy the needs of the user.
Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
