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.
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”.

The base 101 is substantially box-shaped, and includes a substantially rectangular bottom plate 1011, and four side plates 1012 extending up from four sides of the bottom plate 1011. The bottom plate 1011 defines a plurality of through slots 1013 aligning with the third vents 231. In this embodiment, the fan 102 is arranged on an inner side of one of the side plates 1012.
The air duct 103 is substantially rectangular frame shaped and includes a substantially rectangular frame shaped outer sidewall 1031, a substantially rectangular frame shaped inner sidewall 1032, and two connecting plates 1033 respectively connected to front sides and rear sides of the outer sidewall 1031 and the inner sidewall 1032 for closing the outer sidewall 1031 and the inner sidewall 1032. The outer sidewall 1031, the inner sidewall 1032, and the connecting plates 1033 cooperatively form a substantially rectangular air channel 1030. The outer sidewall 1031 defines an inlet 1034 in a bottom, and the inlet 1034 communicates with the base 101. A rectangular frame shaped outlet portion 1035 is formed at a front side of an outer surface of the inner sidewall 1032. The outlet portion 1035 defines an outlet channel 1037 communicating with the air channel 1030. The outlet portion 1035 defines a frame-shaped outlet 1036 communicating with the outlet channel 1037. An area of the outlet 1036 is less than an area of the inlet 1034.
When the fan 102 operates, a first part of airflow 60 coming from outside of the housing 20 flows into the base 101 through the third vents 231 and the through slots 1013, flows into the air channel 1030 through the inlet 1034, flows through the outlet channel 1037, and then flows out of the air blower 100 from the outlet 1036, to form four parts of second airflow 80 along four inner surfaces of the inner sidewall 1032. The four parts of second airflow 80 are forced out of the inner sidewall 1032 and vacuumizes in the inner frame 1032 to form a third airflow 90 flowing from front to rear in the inner frame 1032, to cool the HDD bracket 50, the motherboard 30, and the power supply unit 40. The third airflow 90 guides a fourth airflow 70 entering the housing 20 through the first vents 211, to helps cool the HDD bracket 50, the motherboard 30, and the power supply unit 40, and then flows out of the housing 20 from the second 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.
