Description

computer

The invention relates to a computer, in particular to a computer capable of improving heat dissipation efficiency.

Conventional computers typically use a power supply fan and venting holes provided in the wall of the computer case to dissipate heat. This type of heat dissipation has limited heat dissipation capability. Especially in the case of long computer running time, the heat accumulated inside the computer case cannot be eliminated in time, which seriously affects the normal operation of the computer. Adding a system fan in the computer case can effectively improve the heat dissipation effect of the computer case.

In addition, a data access device such as a hard disk is disposed at a front portion of the computer case, and a central processing unit and an expansion card on the motherboard are respectively disposed at a rear portion of the computer case, and an air inlet hole is disposed at a front wall of the computer case, the computer There are two main disadvantages in the heat dissipation of the chassis: a series of cold air enters through the air inlet hole, first flows through the hard disk, and then cools the central processing unit. This air flow mode increases the cooling flow of the cooling central processing unit while cooling. After the air flows through the hard disk, the temperature of the airflow rises, which is not conducive to the heat dissipation of the central processing unit; the second is that a plurality of expansion card slots are opened on the rear wall of the computer chassis, and the airflow entering by the expansion card slots is caused by the computer chassis. The airflow entering the air inlet hole of the front wall is easy to form eddy current, which reduces the heat dissipation effect of the computer case.

In view of the above, it is necessary to provide a computer that can improve heat dissipation efficiency.

The invention provides a computer, comprising a computer case formed by a front wall, a rear wall and a plurality of side walls, wherein the computer case is mounted with a central processing unit, a system fan and an air hood, the central processing unit Installed in the computer case and adjacent to the side of the rear wall of the computer case, the rear wall of the computer case is provided with a plurality of air inlet holes, and a side wall of the computer case is provided with a plurality of air outlet holes, and the system fan will be cold air After being sucked into the computer case from the air inlet hole of the computer case, the CPU is first passed through the central processing unit, and then guided to the air outlet of the computer case through the air hood to be exported.

Compared with the prior art, the computer can greatly reduce the airflow stroke of the cooling central processor by setting a ventilation structure that is ventilated from the side of the computer chassis from the side of the computer chassis, and the cooling air temperature of the cooling central processor is low, which is improved. The cooling effect of the central processor.

The side plate 91, the partition plate 93 and the top plate 95 are enclosed. Forming a first air duct 935, the side panel 91, the partition plate 93 and the bottom plate 97 are enclosed to form a second air duct 937. The first air duct 935 and the second air duct 937 each form an air inlet and a vertical air inlet. Air outlet.

The motherboard 60 is mounted on the rear of the computer case 10 such that the CPU 40 and the expansion card 50 are adjacent to the air inlet hole 112 of the computer case 10. The air hood 90 is mounted on the front of the computer case 10. The disc assembly 20 is disposed between the air duct cover 90 and the main board 60. The system fan 70 is fixed to the outer side of the rear wall 242 of the hard disc bracket 24 by the air guiding port 2422 of the hard disc bracket 24. The air outlets of the first air duct 935 and the second air duct 937 of the air duct cover 90 face the air outlet 122 of the computer case 10. The air inlet of the first air duct 935 of the air duct 90 faces the CPU 40. The air inlet of the second air duct 937 of the air duct 90 faces the hard disk assembly 20.

Referring to FIG. 4 together, when the cold air is introduced into the computer case 10 from the air inlet hole 112 of the computer case 10 by the system fan 70, a part of the cold air flows through the CPU 40 to absorb heat. The first air duct 935 of the cover 90 is guided to the air outlet 122 of the computer case 10 to be discharged outside the computer case 10, and another part of the cold air flows through the expansion card 50 to absorb heat and further from the air guiding port of the hard disk holder 24. The 2422 flows into the hard disk bracket 24, continues to absorb the heat generated by the hard disks 22, and then flows out from the other air guiding port 2442 of the hard disk bracket 24, and is guided to the computer by the second air duct 937 of the air guiding cover 90.
