Description

Auxiliary cooling system for communication cabinet

technical field

The utility model relates to an auxiliary cooling system for a communication cabinet.

Background technique

At present, with the development of communication equipment, the power of electronic components continues to increase, and the heat generated is also increasing, resulting in an increase in the ambient temperature of the electronic components. Due to the development of integration, multiple subracks need to be installed in a group of cabinets. There are many electronic components in these subracks, which generate a lot of heat and need to be cooled. Otherwise, the high temperature will cause the electronic components to malfunction, cause thermal failure, and even burn. There are multiple subracks in the cabinet, and two types of subracks are usually used for cooling: separated type and centralized type. Although the separated cooling system can effectively cool down the temperature, due to the use of the cooling system alone, a large number of fans and other facilities need to be added, which greatly increases energy consumption, increases noise pollution, and affects the working environment. Although the centralized type can overcome the disadvantages of the separated type, since multiple subframes need to be cooled layer by layer, the cooling medium will gradually heat up, and in severe cases, it will eventually lead to the failure of cooling.
