Abstract: The disclosure discloses an air deflection plug-in box for a forced air-cooled cabinet. The air deflection plug-in box includes a front vertical plate with one or more vent holes, a rear vertical plate with one or more vent holes, two side vertical plates with hangers and an air deflection diaphragm arranged to isolate air areas, wherein the front vertical plate, the rear vertical plate, the two side vertical plates and the air deflection diaphragm are fixedly connected into a whole to distinctively guide cold airflow on one side of the air deflection diaphragm and guide hot airflow on the other side of the air deflection diaphragm. One or more thermal barriers are also arranged on at least one surface of the air deflection diaphragm, and each thermal barrier is made from thermal insulation material.
