Description
- 1. Technical Field
- The present disclosure relates to systems and, more particularly, to a heat dissipating system having an duct cover.
- 2. Description of the Related Art
- It is important to adopt positive heat dissipating mode with a plurality of fans to dissipate heat from an electrical device such as a server. But if one of the plurality of fans is disabled or malfunctions, hot air circumfluence will be produced and heat dissipating for the electrical device will decline. Referring to
FIG. 1 , aheat dissipating system 100 includes achassis 30, and first andsecond fans heat dissipating system 100 is configured for dissipating heat produced by electrical elements from thechassis 30 receiving the electrical elements. When the first andsecond fans second fans chassis 30. If thefirst fan 10 is disabled or malfunctions, a part of hot air blown out of thechassis 30 by thesecond fan 20 will travel into thechassis 30 via thefirst fan 10, which influences heat dissipating for thechassis 30. The same is true if thesecond fan 20 stops working the first fan is working. -
FIG. 1 is a related art heat dissipating system. -
FIG. 2 is an exploded, isometric view of an exemplary embodiment of a heat dissipating system, the heat dissipating system including two duct covers. -
FIG. 3 is an enlarged view of one of the duct covers ofFIG. 2 . -
FIG. 4 is an assembled, isometric view ofFIG. 2 . -
FIGS. 5 and 6 are similar toFIG. 4 , but showing two different using states. - Referring to
FIG. 2 , an exemplary embodiment of aheat dissipating system 200 for an electronic device, such as a server, includes achassis 50, a first heat dissipating member such as afirst fan 52, a second heat dissipating member such as asecond fan 54, and two duct covers 40. - The
chassis 50 is capable of receiving thefirst fan 52 and thesecond fan 54. Twocavities 53 are defined in a sidewall of thechassis 50, respectively aligning with outlets of the first andsecond fans second fans chassis 50 via the twocavities 53. Twocylindrical collars 56 extend from a sidewall of thechassis 50, aligned at an upper portion, and at opposite sides of each of thecavities 53. A pivot hole is defined in eachcollar 56, and the pivot holes are aligned on a straight line. - Referring to
FIG. 3 , eachduct cover 40 includes a rectangularouter flap 42 and a rectangularinner flap 44. Arectangular opening 422 is defined in theouter flap 42. Twocylindrical collars 424 extend from theouter flap 42, aligned at an upper portion, and at opposite sides of the opening 422. A pivot hole is defined in eachcollar 424, and the pivot holes are aligned on a straight line. Twocylindrical pivot shafts 426 extend from opposite ends of a top side of theouter flap 42, to be rotatably engaged in the pivot holes of thecollars 56 of thechassis 50. - The area of the
inner flap 44 is greater than or equal to the area of the opening 422 of theouter flap 42, while smaller than the area of theouter flap 42. Twocylindrical pivot shafts 442 extend from opposite ends of a top side of theinner flap 44, to be rotatably engaged in the pivot holes of thecollars 424 of theouter flap 42. In one embodiment, the outer andinner flaps - Referring to
FIG. 4 , in assembly, thepivot shafts 442 of eachinner flap 44 are rotatably engaged in the pivot holes of thecollars 424 of eachouter flap 42, to rotatably mount theinner flap 44 to theouter flap 42. Thepivot shafts 426 of theouter flap 42 are rotatably engaged in the pivot holes of thecollars 56 of thechassis 50, to rotatably mount theouter flap 42 to the sidewall of thechassis 50. When the first andsecond fans inner flaps 44 cover theopenings 422 of the correspondingouter flaps 42, and theouter flaps 42 cover thecavities 53 of the sidewall of thechassis 50. - Referring to
FIG. 5 , in use, when the first andsecond fans chassis 50 is blown by the first andsecond fans inner flaps 44 to rotate around thepivot shafts 442. Therefore, theinner flaps 44 uncover theopenings 422 of the correspondingouter flaps 42, allowing heat in thechassis 50 being discharged through theopenings 422 of theouter flaps 42. - Referring to
FIG. 6 , when the first andsecond fans chassis 50 is blown by the first andsecond fans outer flaps 42 to rotate around thecorresponding pivot shafts 426. As a result, theouter flaps 42 uncover thecorresponding cavities 53 of thechassis 50, allowing heat in thechassis 50 to discharge through thecavities 53 of thechassis 50. - when the
first fan 52 is disabled or malfunctions while thesecond fan 54 operates at a lower rotating speed, hot air in thechassis 50 is blown by thesecond fan 54, driving the correspondinginner flap 44 to rotate around thepivot shafts 442 to uncover the opening 422 of the correspondingouter flap 42. When thefirst fan 52 is disabled or malfunctions, while thesecond fan 54 operates at a higher rotating speed, hot air in thechassis 50 is blown by thesecond fan 54, driving the correspondingouter flap 42 to rotate around thepivot shafts 426 to uncover thecorresponding cavity 53 of thechassis 50. The outer andinner flaps first fan 52 still cover thecorresponding cavity 53 and theopenings 422 due to gravity of the outer andinner flaps cavity 53 or theopening 422 that corresponds to thesecond fan 54 will not travel into thechassis 50 through thecavity 53 or the opening 442 that corresponds to thefirst fan 52. - It is to be understood, however, that even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and function of the embodiments, the disclosure is illustrative only, and changes may be made in details, especially in matters of shape, size, and arrangement of parts within the principles of the embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
