Abstract

A heat-dissipating system of an equipment cabinet comprises a hot airflow collection cavity, wherein a first side face of the hot airflow collection cavity serves as an equipment cabinet back plate, a plurality of ventilation holes are formed in the first side face, a controller and a first temperature sensor connected with the controller are arranged on the first side face, at least one fan set connected with the controller is arranged inside the hot airflow collection cavity, a second temperature sensor connected with the controller is arranged at the position of an airflow inlet of the equipment cabinet, a hot airflow discharge port is formed in the hot airflow collection cavity and is used for being connected with an airflow return inlet of an airflow conditioner in a machine room through an airflow return guide pipe, the controller is used for outputting a control signal to control fans of the fan set to accelerate when the temperature difference of the temperature of discharged airflow of the equipment cabinet and the temperature of inlet airflow of the equipment cabinet is smaller than a set value, or the controller is used for outputting the control signal to control fans of the fan set to slow down when the temperature difference is larger than or equal to the set value, and the hot airflow discharged from the fans of the fan set is output from the hot airflow discharge port. By means of the heat-dissipating method, the equipment cabinet can be effectively cooled, cold airflow and hot airflow are effectively isolated, and refrigerating efficiency is improved.

Description

technical field [0001] The invention relates to the field of cabinet heat dissipation, in particular to a cabinet heat dissipation method and system, and a computer room hot air flow collection and management system. Background technique [0002] In the communication room, there are generally two layouts for the cabinets, namely, face-to-back layout and face-to-face layout. When the cabinets are arranged face-to-back, cascading heating problems often occur on the air ducts, that is, the hot air discharged from the front cabinets is sucked in by the rear cabinets, which causes the air to be continuously heated, and eventually the air temperature exceeds the allowable intake of the equipment in the cabinet. The temperature of the wind may cause the equipment in the cabinet to alarm or shut down due to high temperature. When the cabinets are arranged in a face-to-face layout, a certain degree of hot and cold airflow can be separated on the air duct, which is significantly impr...
