Problems solved by technology

[0004] In addition, some existing passive heat dissipation schemes mainly consider the heat dissipation of the CPU, and less consideration is given to other components in the system. The air flow is not effectively controlled, so that the actual heat dissipation effect is not very ideal, so they are rarely adopted by system manufacturers. use
[0005] Some computer system manufacturers use liquid cooling technology, and some use heat pipe technology, but these technologies not only have high cost, complicated manufacturing process, but also low reliability, production and maintenance are relatively difficult, and the possibility of engineering is relatively low.

Embodiment Construction

[0030] refer to figure 1 , 2 , the air flow control system of a desktop computer mainframe of the present invention comprises a chassis 1 and a system fan 20 installed inside the air vent 12 provided on the rear panel 11 of the chassis 1, and an air guide groove 30 is arranged in the chassis. The air guide groove 30 has an air inlet 31 and two air outlets, wherein an air outlet 32 ​​is located above the position where the CPU is installed in the chassis (not shown in the figure), and a metal seat and a plurality of heat sinks can also be fixed above the CPU. In the combined heat sink (not shown in the figure), the other air outlet 33 of the air guide groove 30 faces the installation position of the graphics card.

[0031] The structure of the air guide groove 30 is as figure 2 As shown, its main function is to control the air flow, so that the cold air can be blown directly to the main heating components of the system, such as other main heating elements on the motherboard...

Abstract

An air current pipe system includes a machine case and a system fan inside the air hole located on the rear backboard of the machine case. The characteristics of the invention are that there a guiding wind flute possessing the air inlet and at least one air outlet. The air inlet covers the system fan. The air outlet is installed above the CPU inside the machine case. The invention guarantees thatCPU with super-high primary frequency as well as the heating elements on the host board and the hard disks and the plug-in cards can operate under the safe temperature range.

Description

【Technical field】 [0001] The invention relates to an air flow control system for heat dissipation of a desktop computer host. 【Background technique】 [0002] As the main frequency of the computer CPU is getting higher and higher, its heating power is also increasing, and the heating power of the auxiliary equipment that makes up the system is also increasing. Therefore, the problem of heat dissipation restricts the climb of desktop computers to higher performance. The life of electronic products will be shortened sharply as the temperature rises. According to the statistics of the U.S. Air Force Avionics Research Institute, thermal failures of electronic products (including computers) have accounted for more than half of the total failures. Computers with poor heat dissipation design frequently crash or burn out components in severe cases. [0003] The heat dissipation design of traditional desktop computers is generally to install a heat sink on the CPU, and set a CPU fan ...
