Description

An improved computer case

technical field

The utility model relates to the field of computer equipment, in particular to the improvement of the box body structure of a main computer box.

Background technique

Desktop computers are generally equipped with a chassis, and the chassis body is used to install optical drives, hard disks, CPU motherboards, graphics cards, power supplies and other supporting components. At present, computer cases are mainly divided into traditional power supply chassis and ordinary ATX chassis. Among them, the layout of the traditional bottom power supply chassis is that the CPU is placed above the graphics card, so that the power supply and graphics card can only work in a state of self-heating, and the CPU motherboard is integrated. In addition, the traditional power supply is placed under the chassis because the CPU is on the top and the power supply is below, so the 4PIN or 8PIN cable that the power supply supplies power to the CPU is not long enough when the machine is installed, and the dealer must use a high-end power supply (above 400W ) or buy an extension cable, and the cable itself has a certain resistance, the longer the cable, the greater the resistance, and the power supply is more likely to be insufficient; the layout of the ordinary ATX case is that the power supply is at the top, the CPU is below the power supply, and the graphics card is above, and only the graphics card works In the self-heating state, the CPU combines the two parts of the heat generated by the CPU and the graphics card, and the power supply further integrates the three parts of the heat generated by the power supply, the CPU and the graphics card. The unreasonable heat dissipation structure design is the deficiency of the traditional computer case. Since the current high-end power supply, graphics card and CPU fans all use intelligent temperature-controlled fans, when the heat generated by each component is too large to be discharged in time, as the local temperature rises, the fan will increase the speed, resulting in a lot of noise and even clamor. cry.

Utility model content

The purpose of this utility model is to overcome the shortcomings of the above-mentioned prior art, and propose an improved computer case with reasonable heat dissipation arrangement, good heat dissipation effect and low running noise.

The purpose of this utility model is achieved through the following technical solutions: an improved computer case, which is composed of an upper cover, a front panel, a rear panel, a side panel and a bottom panel, the whole is in the shape of a cuboid, and the box is divided into separate parts for installing hard disks and graphics cards. , CPU motherboard, power supply and various hardware installation areas, characterized in that: the motherboard installation area is set in the middle of the cabinet, the graphics card installation area is set above the main board installation area, and the power supply installation area is set below the main board installation area, The upper cover corresponding to the graphics card installation area is provided with cooling holes, and the bottom plate corresponding to the power supply installation area is provided with grid-shaped cooling holes. A vertical cooling air duct is formed on the top; the hard disk installation area is set in front of the motherboard installation area, the front panel corresponding to the hard disk installation area is provided with air inlets, and the rear panel corresponding to the motherboard installation is provided with grid-shaped cooling holes. The air inlet on the front plate and the grid-shaped cooling holes on the rear plate form a horizontal cooling air duct. Further, the grid-shaped cooling holes on the rear panel are equipped with a cooling fan of the rear panel, and the air inlets of the front panel are equipped with a cooling fan of the front panel. The CPU motherboard on the motherboard installation area is installed upside down and connected to the power supply below in a short distance.

The utility model has the following advantages: 1. Since the CPU and the power supply are arranged under the graphics card, the heat dissipated by the graphics card no longer affects components such as the CPU and the power supply. 2. It has two kinds of fast cooling air ducts, horizontal and vertical, and the heat generated by each component can be discharged in time, and the heat redundancy of each part is relatively small. 3. The fans are running at a low speed, especially because the CPU is not disturbed by other heat, the CPU fan can basically keep working in the standby state, so the mute effect of the whole machine is very obvious, which can keep the noise of the computer in the standby state.

Detailed ways

Referring to Fig. 1-Fig. 3, the computer case of the present embodiment is made of loam cake 1, front plate 5, rear plate 8, side plate 6 and bottom plate 9, and the whole is rectangular parallelepiped shape, is divided into and installs respectively hard disk, graphics card, The installation area for CPU motherboard, power supply and various hardware. Wherein, the hard disk installation area 3 is arranged at the front of the cabinet and behind the front panel 5, the graphics card installation area 2 is arranged at the top of the rear of the cabinet, and the motherboard installation area 4 is arranged at the middle rear of the cabinet and below the graphics card installation area 2, And in the same horizontal direction as the hard disk installation area 3 , the power supply installation area 7 is arranged below the motherboard installation area 4 , on the box bottom plate 9 and adjacent to the rear plate 8 . In addition, heat dissipation holes are provided on each surface of the box body, heat dissipation holes 11 are provided on the upper cover 1 corresponding to the graphics card installation area 2, and grid-like heat dissipation holes 91 are provided on the bottom plate 9 corresponding to the power supply installation area 7. The front board 5 is provided with an air inlet 51 corresponding to the hard disk installation area, and the air inlet 51 is used to install the front board cooling fan. A rear plate cooling fan is installed on the grid-like cooling holes 81, and grid-like cooling holes are also arranged on the side plates 6 on both sides. In this way, the air inlet 51 of the front plate and the grid-shaped heat dissipation holes 81 on the rear plate form a horizontal heat dissipation air duct (as shown by the horizontal arrow in Figure 2 ) from the front to the rear; on the bottom plate 9 The grid-shaped cooling holes 91 and the cooling holes 11 of the upper cover 1 form a vertical cooling air duct from bottom to top (as shown by the vertical arrow in FIG. 2 ). Of course, during actual installation, the graphics card can also be directly installed on the CPU motherboard, and the graphics card is still at the top of the CPU motherboard.

Specifically, 1. A vertical air duct is installed on the graphics card for rapid cooling: the graphics card with high heat generation is installed on the upper part of the chassis, and the hot air emitted by the heat dissipation naturally rises and is quickly discharged to the outside of the chassis cover through the vertical air duct, which can Speeding up the heat dissipation of the graphics card itself can also ensure that the heat in the machine is discharged immediately so as not to form heat accumulation: in addition, since the CPU and power supply are under the graphics card, the heat dissipated by the graphics card will no longer affect components such as the CPU and power supply. 2. Fast cooling of hard disk and CPU horizontal air duct: the cooling fan on the front panel can quickly reduce the temperature of the hard disk, and the heat generated by the hard disk and CPU can be quickly discharged through the cooling fan on the rear panel and the side panel fan, thereby reducing the temperature of the machine. 3. The CPU main board on the main board installation area 4 is installed upside down, and it is connected to the power supply below in a short distance. The 4PIN or 8PIN connector of the main board is close to the power supply, so that the power supply will not be picky because of the chassis itself. After installation, the motherboard interface pins are placed on the upper part, with 9 rear wiring holes, and 7mm outer punching side panels, leaving more space without too much space restriction, so it will be more convenient and faster to operate. 4. The chassis provides independent heat dissipation air ducts for the power supply, CPU, and graphics card. The heat redundancy of each part is relatively small, and the heat dissipation fans are all in a low-speed operating state. Especially since the CPU is not disturbed by other heat, the CPU fan can basically maintain It works in standby mode, so the mute effect of the whole machine is very obvious.

Of course, only one preferred implementation mode is listed here, and other equivalent and similar structures should belong to the scope of protection of this patent, and will not be repeated here.
