Description
- 1. Technical Field
- The present disclosure relates to electronic devices, and particularly to an electronic device with an air blower.
- 2. Description of Related Art
- Electronic devices, such as computers, are increasingly used in more fields. During operation, the electronic components generate a lot of heat in housings of the electronic devices. A method for dissipating the heat is to use fans. However, the airflow generated by the fans is often too weak to dissipate heat efficiently.
- Many aspects of the present embodiments can be better understood with reference to the following drawing. The components in the drawing are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present embodiments. Moreover, in the drawing, like reference numerals designate corresponding parts throughout the several views.
-
FIG. 1 is an assembled, isometric view of an embodiment of an electronic device, wherein the electronic device includes an air blower. -
FIG. 2 is an enlarged view of the air blower ofFIG. 1 . -
FIG. 3 is a cross-sectional view taken along the line III-III ofFIG. 2 . -
FIG. 4 is similar toFIG. 2 , but showing the direction of airflow. - The disclosure, including the accompanying drawing, is illustrated by way of examples and not by way of limitation. 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 , an embodiment of an electronic device 10 includes ahousing 20, and anair blower 100 arranged in thehousing 20. Thehousing 20 includes afront wall 21, arear wall 22, abottom wall 23, atop wall 24, and two sidewalls 25 (one of thesidewalls 25 not shown in the figures). Amotherboard 30 is set on one of thesidewalls 25. Apower supply unit 40 is arranged on an upper portion of therear wall 22. A hard disk drive (HDD)bracket 50 for receiving a plurality of HDDs is arranged on a middle of an inner side of thefront wall 21. Thefront wall 21 defines a plurality offirst vents 211. Therear wall 22 defines a plurality ofsecond vents 221. Thebottom wall 23 defines a plurality ofthird vents 231 adjacent to thefront wall 21. - Referring to
FIG. 2 andFIG. 3 , theair blower 100 includes abase 101, afan 102 received in thebase 101, and anair duct 103 located on thebase 101 and enclosing theHDD bracket 50. - The
base 101 is substantially box-shaped, and includes a substantiallyrectangular bottom plate 1011, and fourside plates 1012 extending up from four sides of thebottom plate 1011. Thebottom plate 1011 defines a plurality of throughslots 1013 aligning with thethird vents 231. In this embodiment, thefan 102 is arranged on an inner side of one of theside plates 1012. - The
air duct 103 is substantially rectangular frame shaped and includes a substantially rectangular frame shapedouter sidewall 1031, a substantially rectangular frame shapedinner sidewall 1032, and twoconnecting plates 1033 respectively connected to front sides and rear sides of theouter sidewall 1031 and theinner sidewall 1032 for closing theouter sidewall 1031 and theinner sidewall 1032. Theouter sidewall 1031, theinner sidewall 1032, and the connectingplates 1033 cooperatively form a substantiallyrectangular air channel 1030. Theouter sidewall 1031 defines aninlet 1034 in a bottom, and theinlet 1034 communicates with thebase 101. A rectangular frame shapedoutlet portion 1035 is formed at a front side of an outer surface of theinner sidewall 1032. Theoutlet portion 1035 defines anoutlet channel 1037 communicating with theair channel 1030. Theoutlet portion 1035 defines a frame-shaped outlet 1036 communicating with theoutlet channel 1037. An area of theoutlet 1036 is less than an area of theinlet 1034. - When the
fan 102 operates, a first part ofairflow 60 coming from outside of thehousing 20 flows into thebase 101 through thethird vents 231 and the throughslots 1013, flows into theair channel 1030 through theinlet 1034, flows through theoutlet channel 1037, and then flows out of theair blower 100 from theoutlet 1036, to form four parts ofsecond airflow 80 along four inner surfaces of theinner sidewall 1032. The four parts ofsecond airflow 80 are forced out of theinner sidewall 1032 and vacuumizes in theinner frame 1032 to form athird airflow 90 flowing from front to rear in theinner frame 1032, to cool theHDD bracket 50, themotherboard 30, and thepower supply unit 40. Thethird airflow 90 guides afourth airflow 70 entering thehousing 20 through thefirst vents 211, to helps cool theHDD bracket 50, themotherboard 30, and thepower supply unit 40, and then flows out of thehousing 20 from thesecond vents 221. - In this embodiment, the electronic device 10 utilizes the
air blower 100 to increase airflow, which dissipates heat more effectively. - 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 detail, especially in the matters of shape, size, and arrangement of parts within the principles of the present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
