Abstract
The invention provides a back closed type air exhaust unit ventilation cabinet, comprising a cabinet body and a window, wherein the cabinet body is connected with an exhaust system; a box body is connected in the cabinet body; an operation desk positioned at the top of the box body is also connected in the cabinet body; the exhaust system comprises a back closed type air exhaust unit; the back closed type air exhaust unit comprises a hollow cavity for ventilation, and an air passage wall forming the hollow cavity by enclosing; and the bottom of the air passage wall facing towards one side of the window is provided with venting through holes. According to the structure, by virtue of the venting through holes opened in a centralized mode, the air exhaust in multiple airflow directions in the ventilation cabinet is changed into a single direction, and the airflow is exhausted through a shorted way, so that the generation of turbulent flows and overflow of the airflow are avoided to the utmost extent, and the safety protection degree of operators and the ventilating capacity of the ventilation cabinet are improved. Moreover, condensate liquid generated on an inner wall of the air passage wall is converged at a lower bent part, and is convenient for collection and further treatment. Therefore, the influence on an experimental process and pollution to an experimental space caused by the condensate liquid are reduced.
