Temperature and humidity are the two main reasons for the failure of outdoor rated UPS. The electronic systems may does not contain the design of against harsh environmental conditions, in order to meet the protection of electronic equipment in the indoor and the outdoor environment, the industry invested a lot of time in dealing with the problem of cooling treatment. The cooling treatment of outdoor UPS systems has become a very important issue. In fact, it is only necessary to eliminate the problem of internal heat which is caused by the size limitation and the light radiation in the face, so it can solve the heat dissipation problem of outdoor electronic equipment.
The heat management of the outdoor AC UPS must make a choice for the environmental conditions of the equipment. The equipment is usually divided into indoor equipment and outdoor equipment. Indoor equipment including installation in the central office (CO) or client switching equipment (for different application circuit board), server, router, modem and batteries, depending on end use and decide. Outdoor equipment includes all the equipment that can be seen in the central computer room, but they are installed in a controlled environment.
In addition to ensuring that the device is in the best temperature and humidity conditions, and the telecom engineers must ensure that the equipment to maintain proper heating conditions in a short period of time to the power supply interruption or cooling device failure, until the outdoor UPS cooling device recovery work. Therefore, in the design of appropriate heat dissipation systems, designers must consider the heat dissipation problems may be encountered while in the normal state (steady state) and emergency state.
The above guidelines apply to the central computer room and client equipment as well as outdoor equipment. In addition to the general exchange and processing equipment, the battery device for providing power supply during power outages is also very important. Battery equipment also need to heat dissipation, but also put in a proper ventilation conditions in the house.
