Description

A computer case with improved partition cooling

technical field

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

Background technique

Desktop computers are generally equipped with a chassis, and the chassis body is used to install optical drives, hard disks, CPUs, motherboards, graphics cards, power supplies and other supporting components. At present, computer cases are mainly divided into traditional power supply bottom chassis, common ATX chassis and RTX (inverted 38 degree) chassis, among them, the traditional bottom power supply chassis is arranged with the CPU above the graphics card, which can only make the power supply and graphics card work on its own. In the heat-generating state, the CPU motherboard integrates the heat generated by the two parts of the CPU and the graphics card; 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 from the power supply to the CPU is not long enough when the machine is installed. Either 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 chassis is that the power supply is at the top, and the CPU is at the power supply. Below and above the graphics card, only the graphics card works in its own heating state, while the CPU integrates the heat generated by the two parts of the CPU and the graphics card, and the power supply integrates the three parts of the heat generated by the power supply, CPU, and graphics card. The RTX (inverted 38 degrees) chassis graphics card is located at the top of the chassis, the CPU is located in the middle of the chassis, and the power supply is located at the bottom of the chassis. The CPU, graphics card, and power supply are all independently dissipated and interfere with each other. In particular, it interferes with the heat dissipation of the optical drive and hard disk, and the core components have not achieved absolute partition heat dissipation; the unreasonable design of the heat dissipation structure 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. Therefore, the prior art needs to be improved and improved.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art, and propose a computer case with improved partition heat dissipation, which has reasonable heat dissipation arrangement, good heat dissipation effect and low operating noise.

The purpose of this utility model is achieved through the following technical solutions: a computer case with improved partition heat dissipation, which is composed of a top board, a front board, a rear board, left and right side boards, a bottom board and a main board, and is in the shape of a cuboid as a whole, and is characterized in that: The main board is installed in the middle of the cabinet, and divides the inside of the cabinet into two heat dissipation areas, the left and right heat dissipation areas. The hard disk, optical drive and power supply are installed in the left heat dissipation area, and the graphics card and CPU are installed in the right heat dissipation area; There are cooling holes on the board to form a horizontal air duct running through the front and back; in the left cooling area, the power supply is arranged at the lower part near the rear board, the hard disk is arranged above the power supply, and the optical drive is arranged at the bottom near the front board, and the left cooling area The upper parts of the corresponding front plate and rear plate are also provided with cooling holes to form a horizontal air duct running through the front and back. Further, a hard disk installation frame is arranged above the power supply installation position in the left cooling area. An optical drive installation frame is arranged in the left cooling area and below the front plate. A heat dissipation fan is installed on the heat dissipation holes of the front plate and the rear plate corresponding to the right heat dissipation area. Cooling fans are installed on the cooling holes of the front plate and the rear plate corresponding to the left cooling area.

With this design, the CPU and the graphics card, which generate large amounts of heat, are arranged in an independent installation space—the right heat dissipation area, and 12CM fans are installed on the front and rear panels of the chassis to form horizontal air ducts to directly dissipate the heat-generating components. The heat of the two components is exhausted from the case body. Due to the separation of the motherboard, the residual heat will not interfere with the hard disk, optical drive and power supply. The power supply, hard disk and optical drive with less heat generation are arranged in another space - the left heat dissipation area, the power supply and optical drive are in the lower part, and the hard disk is in the upper part. In a relatively independent space, and the hard disk is above the power supply, it is less affected by the waste heat of the power supply. At the same time, 8cm fans can be installed on the front and rear panels to form a horizontal air duct, which can accelerate the discharge of waste heat and dissipate heat for the hard disk.

The utility model has the following advantages: 1. The mainboard divides the chassis into two independent heat dissipation spaces; the CPU and the graphics card are located in an independent space, and the heat emitted by the graphics card and the CPU no longer affects components such as power supply, optical drive and hard disk; The optical drive, power supply and hard disk are in another independent heat dissipation space; realizing partition heat dissipation of core components. 2. Both heat dissipation areas can realize horizontal heat dissipation air ducts, and the heat generated by each component can be discharged in time, and the heat redundancy of each part is relatively small, especially for the current major accessories that use temperature-controlled fans (the characteristics of temperature-controlled fans It is good heat dissipation, low speed and low noise), which reduces the speed of the fan and reduces the noise. 3. In the case of partitioned heat dissipation, the configuration requirements of other accessories are not increased, and even the requirements for the length of power output wires of each component are shortened.

Detailed ways

Referring to Fig. 1-Fig. 4, the computer case of the present embodiment is made of front plate 1, rear plate 2, base plate 4, top plate 3, left side plate 14, right side plate 15 and mainboard 5, and the box body is rectangular parallelepiped as a whole , the box is divided into two independent heat dissipation zones - left heat dissipation zone 7 and right heat dissipation zone 6 (as shown in Figure 3 and Figure 4), the right heat dissipation zone 6 accommodates the graphics card and CPU, and the left heat dissipation zone 7 accommodates the power supply 19, 17 3.5-inch hard drives, 18 2.5-inch hard drives and 16 optical drives.

Among them, in the right heat dissipation area 6, there are six installation threading holes on the motherboard 5, the graphics card is located below the CPU (not shown in the figure), and two groups of heat dissipation holes are provided on the front plate 1 corresponding to the right heat dissipation area 6 11. Located on the upper and lower parts of the front panel 1 respectively, it is used to install a 12CM fan and water cooling; in the right cooling area 6 corresponding to the upper part of the rear panel 2, there are also cooling holes for installing an 8CM fan, so that the right cooling In the zone 6, a horizontal air duct passing through the front and back is formed between the front panel 1 and the rear panel 2.

In the left heat dissipating area 7, the power supply 19 is placed in the power supply installation position 8 of the lower part, which is located at the position of the base plate 4 close to the bottom of the rear plate 2, and the hard disk installation frame 9 is located directly above the power supply installation position 8, and the hard disk installation frame 9 can be Install a 3.5-inch hard disk 17 and a 2.5-inch hard disk 18. A heat dissipation hole 12 is provided on the left cooling area 7 corresponding to the upper part of the rear plate 2 and at a position corresponding to the hard disk mounting bracket 9 for installing an 8CM fan. The optical drive mounting bracket 10 is located on the bottom plate 4 At the junction with the front panel 1, the optical drive 16 is installed on the optical drive installation frame 10, and the front panel 1 above the optical drive installation frame 10 is also provided with cooling holes, which are also used to install an 8CM fan, and are connected to the The cooling holes 12 form a horizontal air passage running through the front and back.

In this way, the left and right heat dissipation areas in the box are formed with horizontal air ducts running through the front and back.

Specifically, the CPU and the graphics card (not shown in the figure) that generate a large amount of heat are separated by the main board 5 in an independent space for heat dissipation, and can pass through the cooling holes and fans of the front board 1 and the rear board 2, and then go forward and back out of the ground. The heat generated by the graphics card and CPU is quickly discharged out of the chassis, ensuring that the heat of the CPU and graphics card is discharged in the first place, so that heat accumulation will not form and other components will not be affected. Hard disks 17, 18, optical drive 16 and power supply 19 are separated in another independent heat dissipation space by motherboard 5. Power supply 19 sucks cold air through the through hole of left side plate 14, and discharges hot air through the fan on the top of rear plate 2. The heat is directly discharge. The residual heat of the optical drive 16, according to the principle of air rising, reaches the position of the top plate 3, and is dissipated by the forward-backward air duct formed by the two 8CM fans on the front plate 1 and the rear plate 2. At the same time, the forward-backward 8CM fan directly The hard disk 17,18 accelerates the heat dissipation of the hard disk 17,18. Due to the relatively close location of each component, the requirements for the output wire of the power supply are greatly shortened. Although the installation position is changed, there is no special requirement for each component. Therefore, it will be more convenient and faster to operate. The chassis provides independent cooling air ducts and spaces for the power supply 19, CPU, and graphics card. The thermal redundancy of each part is relatively small, and the cooling fans are all running at low speeds, so the mute effect of the whole machine is also 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.
