First, Communication switching power supply is communications infrastructure, once appear fault will lead to serious consequences. the statistical results confirmed in our practice work, the loss of data, hardware failures and downtime is mainly due to the failure of communication switching power supply system. And the changes of working environment's temperature in the power supply room are related to switch power supply's stable performance and service life, therefore, the power choose the appropriate cooling way, can guarantee the reliable using for communication power supply. Now we will simply introduce the advantages and disadvantages for Communication switching power supply's cooling method. Second, Communication switching power supply cooling technology design should meet the performance requirements of industry all technologies first. For more adaptable to the special environment of telecommunication room, they required the cooling patterns have adaptability on the environment temperature changes. At present rectifier commonly used natural cooling, a pure fan cooling, natural cooling and fan cooling combining three types cooling ways. The advantage of natural cooling is no mechanical failures, high reliability; No air flow, dust little benefit heat; No noise etc. The main drawback is the large heat sink bulk and weight. The advantage of pure fan cooling equipment is light weight, low cost. The major disadvantage is for MTBF the fan is shorter than rectifier's 100000 hours , , if the fan breakdown it will be a big influence for the failure rate of power supply. The technology of fan and natural cooling combination has effectively reduced equipment bulk and weight ,the high service life, Fan fault adaptability characteristics, etc. Third, Due to the changes of environmental temperature and load, the power dissipation of heat energy at work condition, using fan and natural cooling combination can be faster to distribute out heat energy. In this way, while increasing the cooling fan, the radiator area can be reduced, it makes the power components work in a relatively stable temperature conditions, service life will not be affected by external conditions change. This will not only overcome the shortcoming of the fan cooling have limitation for power components thermal regulation, but also avoid the low service life impact the rectifier's overall reliability. Especially in the room temperature is unstable, to use a combination of cold air and self-cooling technology has better cooling performance. In this way, between the pure pan cooling and natural cooling, the materials of rectifier have low weight and easy maintenance. Therefore, to ensure communication reliability stability for switching power supply's rectifier, reduce its working temperature is a key technology. Using the intelligent air cooling and the self-cooling combination technology. it has more strong adaptability to the environment , long service life, reliable and stable technical advantage, etc. |
