## Background
BACKGROUND
1. Technical Field
The present disclosure relates to computer systems, and more particularly to a computer system with a waste heat recycling device.
2. Description of Related Art
Computer systems have attained widespread use in many segments of today's modern society. Computer systems are typically provided with enclosures, which protect the operating components therein. Many components of computers generate heat during operation, making it necessary to cool those components so that proper operation continues. Because of the confined space of the enclosure, natural heat dissipation is difficult. Cooling strategies for computers usually rely upon forced airflow through the computer enclosure. It can be a waste to exhaust the heat which can be reused directed to the air from the computer system, for example, the heat air can be guided to warm hand or warm cold room.

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 FIG. 1, one embodiment of a computer system includes a computer 100, an air-duct 30, two retaining mechanisms 50, and a fan 70. The two retaining mechanisms 50 are respectively used for connecting an end of the air-duct 30 to the computer 100, and another end of the air-duct 30 to the fan 70.
The computer 100 has an enclosure. The enclosure has a heat air outlet 110 to dissipate heat from the computer 100. In one embodiment, the air-duct 30 is a flexible pipe.
Referring to FIG. 2, the retaining mechanism 50 includes a clip 51 and a support ring 59. The support ring 59 includes a circular main body 592 and two ridges 594 located on the main body 592. Each ridge 594 extends along a periphery of the circular main body 592 and is located on a middle portion of the main body 592. In one embodiment, the clip 51 can further include two clasped sub-clips 53 and 55. The two sub-clips 53 may have same structure or corresponding structures in different embodiments. Take sub-clip 53 for example, the sub-clip 53 has a locking portion 534 and two retaining portions 537 located at two end portions of the locking portion 534. A slot 532 is defined in a middle portion the locking portion 534 corresponding to the ridge 594. Two locking tabs 533 are located on the locking portion 534 to connect to the computer 100 or the fan 70. The sub-clip 55 also has a locking portion 554, two locking tabs 553, two retaining portions 557 and a slot 552. Alternative structures of the sub-clips 53 and 55 may be incorporated onto the retaining portion 537.
In one embodiment as shown in FIG. 2, each retaining portion 537 has a buckle 5372, and a retaining hole 5572 is defined in each retaining portion 557 to engage with the buckle 5372.
Referring to FIG. 3, in another embodiment, a clip may include two sub-clips 57 having the same structure. Each sub-clip 57 includes two retaining portions 577, one of the two retaining portions 577 has a buckle 5772. The two sub-clips 57 can be clasped to each other.
Two hanging holes 5374 and 5574 are respectively defined in the retaining portion 537 and the corresponding retaining portion 557. The two hanging holes 5374 and 5574 are aligned with each other.
Referring to FIG. 4, when assembling the computer system, the support ring 59 is aligned with an edge of the air-duct 30. The air-duct 30 extends and covers on the support ring 59. The two sub-clips 53, 55 are respectively mounted to the support ring 59 with the slots 532 and 552 respectively engaged with the corresponding ridges 594. The two sub-clips 53 and 55 are clasped to each other with the buckles 5372 received in the corresponding retaining holes 5572. The edge of the air-duct 30 is sandwiched between the main body 592 and the locking portions 534 and 554 by engagement of the support ring 59 and the clip 51. The two hanging holes 5374 and 5574 are aligned. The fan 70 is fixed to the retaining mechanism 50 on the locking tabs 533 and 553 to cover the air-duct 30. The retaining mechanism 50 is positioned between the computer 100 and the inlet of the air-duct 30 is fixed in a similar way.
Referring to FIG. 5, the fan 70 includes a connector 75, such as a USB port, to receive power from a USB connector of the computer 100. The fan 70 can accelerate the removal of heat air from the computer 100. The heated air can be recycled from the air-duct 30.
It is also to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of preferred embodiments, together with details of the structures and functions of the preferred embodiments, 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 disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
