The invention relates to an active flow control structure and method for a bathyscaphe. According to the method, on the basis of an existing outboard heat exchange system of the bathyscaph, seawater after heat exchange is guided to the position near a disordered flow removal surface-stern elevator of a flow field through a flow guide pipe, and active optimization of the flow field of the bathyscaph is achieved through quantitative control over drainage flow rates of the upper side and the lower side of a main body molded line flow removal surface through a pipeline axial flow pump; therefore, the requirements for stability and controllability of the bathyscaphe are met, and the method has important significance for improving the underwater navigation and operation efficiency of the bathyscaphe. 本发明涉及一种深海潜水器用主动控流结构及控流方法；该方法基于深潜器现有舷外换热系统，将换热后的海水经导流管导向流场较为紊乱的去流面-艉升降舵附近，通过管道轴流泵对主体型线去流面上、下两侧排流速率的量化控制，实现对深海潜水器流场的主动优化，提高舵效从而满足深海潜水器的稳定性和操控性需求，对提升深海潜水器水下航行与作业效率具有重要意义。
