Abstract
1. Вентилятор, содержащий два набора лопастей, вращающихся во встречном направлениях, отличающийся тем, что лопасти, придающие начальное ускорение газу, содержат в себе качество как осевого, так и центробежного вентилятора.2. Вентилятор по п. 1, отличающийся тем, что лопасти второго набора имеют саблевидную линию кромки, ориентированную в каждой точке лопасти перпендикулярно к вектору скорости входящего в них газа.3. Вентилятор по п. 1, отличающийся тем, что лопасти второго набора имеют определенный угол атаки к вектору скорости входящего газа и обеспечивают ламинарный поток.4. Вентилятор по п. 1, отличающийся тем, что профиль поперечного сечения лопастей второго набора обеспечивает изменение вектора скорости газа в осевом, центробежном и тангенциальном направлениях.1. A fan containing two sets of blades rotating in the opposite direction, characterized in that the blades giving the initial acceleration to the gas contain the quality of both an axial and a centrifugal fan. The fan according to claim 1, characterized in that the blades of the second set have a saber-shaped edge line oriented at each point of the blade perpendicular to the velocity vector of the gas entering them. The fan according to claim 1, characterized in that the blades of the second set have a certain angle of attack to the velocity vector of the incoming gas and provide a laminar flow. The fan according to claim 1, characterized in that the cross-sectional profile of the blades of the second set provides a change in the gas velocity vector in the axial, centrifugal and tangential directions.
