Problems solved by technology

[0003] Existing computers or cabinets often experience high temperatures after long-term use, and fans need to be used for heat dissipation and cooling. However, the existing heat dissipation fan structure and heat dissipation mode are relatively simple, which will affect the normal operation and service life of surrounding devices, and has certain shortcomings.

Embodiment 1

[0026] see Figure 1~4 , in an embodiment of the present invention, a frictional damping speed control computer cooling fan includes a main body 10, an annular flange is provided on the outer ring of the upper end of the main body 10, and a plurality of installation holes 1 are distributed in the circumferential direction of the annular flange, Through the installation hole 1, it is convenient to fix the device on the computer case or cabinet. The outer side of the main body 10 is equipped with a spiral heat dissipation pipe 11. The cross section of the spiral heat dissipation pipe 11 is circular. The spiral heat dissipation pipe 11 is made of copper-aluminum alloy material. 1 / 2 of the radial direction of the spiral heat dissipation pipe 11 is embedded on the outer wall of the main body 10, and the spiral heat dissipation pipe 11 can play the role of conduction and heat dissipation. The upper part of the inner cavity of the main body 10 is cylindrical and the lower part is a co...

Embodiment 2

[0030] see Figure 1~4 , the difference between this embodiment and embodiment 1 is:

[0031] In this embodiment, the motor fixing mechanism includes a motor fixing ring 6 fixed on the biaxial extension motor 18, a plurality of horizontal support rods 5 are arranged on the outer ring of the motor fixing ring 6, and the outer ends of the support rods 5 Sliding sleeve 12 is installed, and three support rods 5 are evenly distributed in the circumferential direction. The number of guide support mechanisms is the same as the number of support rods 5. Rod 14, the vertical portion of the U-shaped guide rod 14 is slidably connected with the sliding sleeve 12, and the upper and lower sides of the sliding sleeve 12 are also sleeved with a spring 13 on the vertical portion of the U-shaped guide rod 14. The spring 13 can elastically support the sliding sleeve 12 .

[0032]The friction damping speed control computer heat dissipation fan is convenient to fix, and the dustproof effect is g...

Abstract

The invention discloses a frictional damping speed controlling computer cooling fan. The frictional damping speed controlling computer cooling fan comprises a main body, a double-axis extension motoris mounted at the center part of the inner side of the main body through a motor fixing mechanism, fan blades are mounted at the lower end of a motor shaft of the double shaft extension motor, air inan inner cavity of the main body can flow from top to bottom through the fan blades, a guiding supporting mechanism is arranged on the inner side wall of the main body, the guiding supporting mechanism is used for conducting up and down elastic moving guiding on the motor fixing mechanism, a multi-hole piston plate is slidably arranged on the inner side of a cooling liquidcylinder body in a fit mode, a connecting rod is mounted on the lower side of the multi-hole piston plate, the connecting rod stretches out from the lower end of the cooling liquid cylinder body, a universal ball shell is mounted at the lower end of the connecting rod, the universal ball shell is internally provided with a universal ball in a fit mode, and a plurality of cooling liquid tubes are arranged on an outer ringof the upper part of the cooling liquid cylinder body in the circumferential direction. The frictional damping speed controlling computer cooling fan is novel in structure, reasonable in design, and good in heat dissipation effect and facilitates popularization.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a friction damping speed control computer cooling fan. Background technique [0002] A computer, commonly known as a computer, is an electronic computing machine used for high-speed calculations. It can perform numerical calculations, logic calculations, and storage and memory functions. Intelligent electronic equipment consists of hardware systems and software systems. Computers without any software installed are called bare metal, which can be divided into five categories: supercomputers, industrial control computers, network computers, personal computers, and embedded computers. More advanced computers include: Biological computer, photonic computer, quantum computer, etc. The cabinet is generally made of cold-rolled steel plate or alloy to store computers and related control equipment. It can provide protection for storage equipment, shield electromagnetic interference, an...
