Problems solved by technology
From the above description, it can be known that the noise of the power supply fan is relatively easy to solve, and most of the mainframes of the existing computers have eliminated the optical drive. Therefore, the noise source of the mainframe of the current computer mainly comes from the CPU fan and the hard disk. How to reduce the noise of the CPU fan of the computer And hard disk noise is the main problem that needs to be solved at present

The invention discloses a computer comprehensive noise reduction device. The invention discloses a computer comprehensive noise reduction device. The device comprises a case, silencing layers are arranged on the two sides of the case; the outer side of the silencing layer is connected with the radiating pipe; the two sides of the bottom of the sealing shell are connected with an inlet and an outlet of an air condenser through pipelines. A heat dissipation shell is arranged on the periphery of the central processing unit. Heat dissipation pipe and outer side of heat dissipation shell, a coolingfan is arranged at the position, corresponding to the central processing unit, of the case; a silencing cover is arranged on the outer side of the cooling fan; a silencing shell is arranged at the bottom in the case; a hard disk is placed in the silencing shell, the two sides of the top of the hard disk are each provided with a fixing block, the fixing blocks and the silencing shell are fixed through first nuts and screws, the two sides of a rear opening of the sealing shell are each provided with a vertical plate, a baffle is arranged between the two vertical plates, inserting grooves are formed in the corresponding positions of the vertical plates and the baffles, and the two ends of the baffles can be located in the corresponding inserting grooves. The noise of a central processing unit fan and the noise of a hard disk of the computer can be effectively reduced, so that the noise of the computer is effectively reduced, and the influence of the computer noise on people is avoided.
Description
technical field [0001] The invention belongs to the field of computers, in particular to a comprehensive computer noise reduction device. Background technique [0002] The main sources of computer noise are: power supply fan noise, CPU fan noise, optical drive noise, and hard disk noise. The noise of the power supply fan is divided into rotation noise and vibration noise. The rotation noise is generally caused by the lack of lubrication of the fan bearing. You can drop a few drops of light lubricating oil on the fan bearing. The vibration noise is generally caused by the imbalance of the fan blades and the blades on the shaft. Looseness and excessive bearing and clearance. If individual blades accumulate dirt, just remove the dirt; if the fan blades are defective, asymmetrical, or the bearing clearance is too large, it is best to replace with a new power supply fan. The CPU fan and fan blades are places that are likely to cause noise. After long-term use, the bearings of t...
