Description

Cooling device for main chassis of desktop computer

The utility model relates to a heat dissipation device for a main box of a desktop computer, which belongs to the improvement of the heat dissipation system of the main box of the desktop computer.

The heat dissipation problem in the main box of traditional desktop computer is to draw the heat inside the box out of the box through the power supply fan and system fan, so as to maintain the normal operation of the mainframe. When using a high-frequency, high-power central processing unit (CPU), the temperature of the core part of the processor is high and the heat generated is large. Only the traditional heat dissipation method cannot guarantee the normal operation of the host.

The purpose of the utility model is to provide a heat dissipation device for the main box of a desktop computer. In view of the above problems, the heat generated when the central processing unit is working is forcibly removed, the ambient temperature of the processor is maintained, and the normal operation of the main machine is ensured.

The purpose of this utility model is achieved in that

A heat dissipation device for a main box of a desktop computer. A cold air inlet is installed on the front panel of the main box, an exhaust fan and an air outlet are installed on the rear panel of the box, and a high-power, high-power Frequency central processor, characterized in that a cold wind window is also installed on the right side panel of the main engine box, and a diversion wind cover is connected between the cold wind window and the exhaust hood of the central processing unit, and the air inlet of the diversion wind cover is sealed. It is connected to the cold air window on the right side panel of the box body, and the air outlet of the air deflector hood is sealed and connected to the exhaust hood of the processor.

The installation of the air deflector is to introduce the cold air outside the box directly to the exhaust hood of the CPU, increase the exhaust capacity of the exhaust hood of the processor, take away the heat generated by the processor more effectively, and maintain The ambient temperature of the processor ensures the normal operation of the host.

The structure of the utility model is described in detail in conjunction with the accompanying drawings;

A cooling device for a main box of a desktop computer. A cold air inlet 6 is installed on the front panel of the main box 1, and a floppy disk box 8 and a hard disk box 7 are provided. The main board of the box 1 is equipped with computer components and high-frequency components. , High-power central processing unit 9. An exhaust fan 4 and an air outlet 5 are installed on the rear panel of the box. The rotation of the motor makes the fan 4 rotate, and the heat generated by the electrical components in the box 1 is removed from the air outlet 4, and the cold air flows from the front panel of the box 1. The air inlet 6 is supplemented to form a thermal cycle in the box to keep the main engine working normally. When using high-frequency, high-power central processing unit 9 (CPU), the temperature of the core components of the processor is high, and the operating temperature is as high as 40°C, which generates a lot of heat, and the traditional heat removal method cannot guarantee the normal operation of the host work.

The utility model is characterized in that a cold wind window 2 is installed on the right side plate of the main engine box body 1, and the air guide cover 3 is connected between the cold wind window 2 and the exhaust cover 10 of the central processing unit 9, and the air guide cover 3 The air inlet 31 is sealed and connected to the cold wind window 2 on the right side panel of the box body, and the air outlet 32 of the air guide cover 3 is sealed and connected to the exhaust hood 10 of the processor.

The wind deflector 3 is integrated with left and right symmetrical cavities made of resin material, and the shape is "" type. The air inlet 31 and the air outlet 32 of the wind deflector 3 are arranged parallel to each other in opposite directions. The effect of deflector hood 3 is that the cold air outside the box is directly introduced into the exhaust hood 10 of the central processing unit through the cold wind window 2 on the right side panel of the casing naturally, and the core area of the processor is forced to dissipate heat and cool down, so that A large amount of heat is discharged from the heat conduction holes on both sides of the processor exhaust cover 10 to reduce the ambient temperature of the processor, and the heat in the cabinet is discharged out of the cabinet by the rear panel exhaust fan 4 to achieve the purpose of heat dissipation and cooling. Due to the existence of the air guide cover 3, the noise inside the box is also reduced. After testing, the noise in the box is reduced by 3 decibels.

For large-scale desktop computer mainframe casings, the temperature of the core components of the processor used is higher, and the cold air is naturally introduced into the exhaust hood 10 of the processor by the deflector hood 3 alone, which cannot solve the above problems. The technical solution proposed by the utility model is to install an electric blower fan 12 at the air inlet 31 of the air guide cover 3, and forcefully blow cold air into the exhaust cover 10 of the processor, thereby realizing the purpose of forcibly dissipating heat and cooling .

The utility model provides a cooling device for a main box of a desktop computer, which uses a guide wind cover to forcibly introduce cold air from outside the box to the processor, and forcibly cools down the core area of the processor, thereby solving the problem of heat dissipation in the main box. The structure is simple and the effect is remarkable.
