大功率短波机房通风系统的改造

Renovation of ventilation system in high power short wave machine room

短波主要是指频率介于3MHz~30MHz之间的一种无线电波,目前在我国的电话通信以及广播行业大功率短波通信中得到广泛的普及和应用。由于大功率短波发射机耗电量大、产生热量高、高温持续时间长,因此对机房通风系统的通风散热性能提出了更高的要求,尤其对使用年限较长的通风系统来说,若不及时予以改造和更新,则不仅会缩短系统的使用寿命,甚至会导致系统瘫痪,进而使短波发射机等设备严重受损。基于此,文章以容纳400台大功率短波发射机的机房为例,对机房通风系统的改造方案予以全面阐述,通过改造方案验证改造以后的通风系统是否满足大功率短波发射机的运行和使用要求。

Short wave mainly refers to a type of radio wave with frequencies between 3 MHz and 30 MHz.Currently,high-power short wave communication has been widely popularized and applied in China's telephone communication and broadcasting industries.Due to the high power consumption,high heat generation,and long high-temperature time of high-power shortwave transmitters,higher requirements are put forward for the ventilation and heat dissipation performance of the computer room ventilation system.Especially for the ventilation system with a long service life,if it is not renovated and updated in a timely manner,it will not only shorten the service life of the system,but more seriously,it will also cause system paralysis,leading to serious damage to equipment such as shortwave transmitters.Based on this,the article will take the computer room that houses 400 high-power shortwave transmitters as an example to comprehensively elaborate on the renovation plan of the ventilation system in the computer room.Through the implementation of the renovation plan,it will be verified whether the ventilation system after the renovation meets the operation and usage requirements of high-power shortwave transmitters.
