1. Technical Field
The present disclosure relates to a computer system with an airflow blocking plate.
2. Description of Related Art
Typically, a heat sink is secured to a motherboard of a computer system, to dissipate heat generated by a central processing unit (CPU). The disk drive also generates heat when working. Some heat generated from the disk drive is usually cooled by the heat dissipating component of the CPU. Air flows through a drive bracket, a system fan, some peripheral component interconnects, and a power supply bracket. However, some heated air may continue to circulate within the computer enclosure or once vented flow back into the computer system. This decreases efficiency for dissipating the heat generated by the disk drive in the computer system.
Many aspects of the embodiments can be better understood with references to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
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.

The chassis 10 can have any geometric shape, configuration, or orientation suitable for housing an electronic device therein. For simplicity and as an aid to the description, the chassis 10 is depicted as a cuboid (i.e., a partially or completely enclosed rectangular box) will be described herein, although other equally effective geometric shapes and configurations may exist in other exemplary embodiments. The chassis 10 includes a chassis bottom wall 11, a first chassis sidewall 13, a second chassis sidewall 14, a chassis rear wall 15, and a chassis front wall 17. In one exemplary embodiment, the chassis front wall 17 is parallel to the chassis rear wall 15 and perpendicular to the chassis bottom wall 11. The first chassis sidewall 13 is parallel to the second chassis sidewall 14 and perpendicular to the chassis bottom wall 11 and the chassis front wall 17. A plurality of first ventilation holes 131 is defined in the chassis front wall 13, and a plurality of second ventilation holes 151 is defined in the chassis rear wall 15. In one embodiment, the first ventilation holes 131 and the second ventilation holes 151 are respectively arranged in a rectangular area. The second disk drive 80 is secured on the chassis bottom wall 11 at a corner between the chassis front wall 17 and the first chassis sidewall 13.
The power supply bracket 20 is arranged at a corner between the second chassis sidewall 14 and the chassis rear wall 15.
The airflow blocking plate 30 includes a first blocking portion 31 and a second blocking portion 33 connected to the first blocking portion 31. In one embodiment, the airflow blocking plate 30 is L-shaped. Two securing holes 311 are defined in the first blocking portion 31. A through hole 331, four mounting holes 333 and an opening 335 are defined in the second blocking portion 33. The four mounting holes 333 are respectively distributed at four corners of the second blocking portion 33. Four of the six locking components 90 are respectively inserted into the four mounting holes 333 and the four holes 71 of the system fan 70 aligned with the holes 333, mounting the second blocking portion 33 to the system fan 70. The opening 335 is used for one or more cables passing through.
The motherboard 40 is mounted between the power supply bracket 20 and the first chassis sidewall 13. Four expansion cards 41 and a heat sink 43 can be mounted on the motherboard 40. The expansion cards 41 are located between the power supply bracket 20 and the heat sink 43. The heat sink 43 includes a plurality of fins 431 and a fan 433 on the fins 431.
The drive bracket 60 can be located in the chassis 10 at a corner between the first chassis sidewall 13 and the chassis front wall 17. The first ventilation holes 131 defined in the chassis front wall 13 are near the drive bracket 60. The drive bracket 60 includes a drive bracket bottom plate 62, two first drive bracket side plates 61 perpendicular to drive bracket bottom plate 62, and two second drive bracket side plates 63 perpendicular to the drive bracket bottom plate 62. In one embodiment, the two first drive bracket side plates 61 are located on two edges of the drive bracket bottom plate 62, and the two second drive bracket side plates 63 are located on other two edges of the drive bracket bottom plate 62. Two screw holes 611 are defined in each first drive bracket side plate 61. Four threaded holes 631 are defined in each second drive bracket side plate 63. Four fastening components (not shown) are inserted into the four threaded holes 631 and the four fixing holes 51 of the first disk drive 50, to secure the first disk drive 50 to each second drive bracket side plates 63.

In use, air flows into the chassis 10 via the first ventilation holes 131 of the chassis front wall 13, through the second disk drive 80, and passes through the system fan 70 and the through hole 331 in the second blocking portion 33. Then the air flows through the expansion card 41 and the power supply bracket 20, and out of the chassis 10 via the second ventilation holes 151 in the chassis rear wall 15. With the airflow blocking plate 30, space inside the chassis 10 is divided into a first space and a second space. The second disk drive 80 and the system fan 70 are positioned in the first space, and the motherboard 40, and the power supply bracket 20 are positioned in the second space. Air flowing from the first space to the second space cannot return back to the first space, so heat generated from the second disk drive 80 can be effectively removed.
It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions of the 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.
