Description

technical field [0001] The invention belongs to the technical field of low-noise air-cooling and heat dissipation of special communication electronic equipment, and in particular relates to an intelligent management device and method for equipment heat dissipation fans. Background technique [0002] At present, the power consumption of various complete equipment is getting higher and higher, and the heat dissipation of the equipment is very important to the reliability of the work. The heat generated by high-power active devices will cause the temperature of other chips in the board and other boards in the device to rise. If the heat is not exported in a timely and effective manner, it may cause long-term damage to the boards and chips in the device. Work in a higher temperature environment, resulting in deterioration or damage to device performance. Therefore, choosing a suitable heat dissipation method and carrying out an optimal design are the basic conditions to ensure ...

Problems solved by technology

Natural air cooling usually adopts the method of installing heat sinks on the heating unit, and uses the air convection caused by the difference in density between hot and cold air to export heat. Machine equipment

Forced air cooling is to use the fan to force air convection to transfer the heat on the heat sink to the surrounding environment in time to achieve the purpose of heat dissipation. It has a simple structure, relatively low price, and is safe and reliable. However, the high-speed rotation of the heat dissipation fan will generate high Air turbulence noise and electromagnetic signal interference, the working life of the fan also has a certain time limit

The principle of water cooling is similar to that of forced air cooling, except that liquid is used instead of gas as the heat transfer medium, and water pipes are used instead of air ducts, so the heat transfer efficiency will be higher, but the structure is complex and the cost is high, and it is not currently used in equipment. too broad
