Heat exchange performance evaluation control system and method for communication cabinet

Abstract

The invention discloses a heat exchange performance evaluation control system and method for a communication cabinet, and relates to the technical field of communication. Different control strategiesare adopted for the temperature and the humidity of each part in a communication cabinet, and the efficient temperature control, energy saving and condensation prevention are realized through the start-stop and linear speed regulation of internal and external fans and the linkage of a temperature sensor, a humidity sensor and a heating and dehumidifying device, and the service life of the controldevice is prolonged. The control system adjusts the temperature and humidity data in real time through the feedback quantity of each sensor, and starts and stops the heating and dehumidifying device,thereby achieving the precise control of the temperature and humidity in the cabinet. Meanwhile, the performance of the fans is judged by monitoring the flow and the heat exchange amount of the innerfans and the outer fans in real time, and an alarm is provided for the blocking state.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a heat exchange performance evaluation control system and method of a communication cabinet. Background technique [0002] The heat exchanger is an important component for the communication equipment in the communication cabinet to realize heat exchange and transfer during the working process. After the heat exchanger has been used for a long time, dirt will accumulate in the air duct of the fan, which will affect the heat transfer capacity; the fan will run at full speed for a long time, which is not conducive to prolonging the service life and saving energy; Locating faults will cause serious energy waste and environmental degradation, and cause irreparable losses to the performance of communication equipment, such as chip overheating, system crashes, etc. Therefore, real-time monitoring of the health status of heat exchangers is of great significance. [0003] In the c...

Problems solved by technology

After the heat exchanger has been used for a long time, dirt will accumulate in the air duct of the fan, which will affect the heat transfer capacity; the fan will run at full speed for a long time, which is not conducive to prolonging the service life and saving energy; Locating faults will cause serious energy waste and environmental degradation, and cause irreparable losses to the performance of communication equipment, such as chip overheating, system crashes, etc. Therefore, real-time monitoring of the health status of heat exchangers is of great significance

[0003] In the communication cabinet, when the cabinet is in a high-temperature and high-humidity environment, if the surface and internal temperature of the communication equipment in the cabinet drops below the dew point temperature, condensation will occur on the surface of the communication equipment, which will degrade the performance of the equipment in all aspects, such as The insulation level of insulating materials is reduced, causing phenomena such as creepage and flashover; parts are corroded; electronic components are damaged, etc.
