<p><P>PROBLEM TO BE SOLVED: To provide a stirring device capable of stirring a fluid with a compact and simple structure and without generating variation in temperature. <P>SOLUTION: The stirring device 1 provided inside a cylindrical flow passage 10 for stirring a fluid by generating a swirling flow in the fluid includes: first and second circulating parts 11 and 12 dividedly formed along the flow passage 10; an upstream side shielding part 4 for closing parts of upstream side openings of the first and second circulating parts 11 and 12; and a downstream side shielding part 6 for closing parts of the downstream side openings 5 of the first and second circulating parts 11 and 12 so as not to overlap the upstream side openings 3 of the first and second circulating parts 11 and 12 with the flow direction of the fluid, and the downstream side openings 5 thereof. The upstream side shielding part 4 is arranged alternately with the upstream side openings 3 of the first and second circulating parts 11 and 12, and the downstream side shielding part 6 is arranged alternately with the downstream side openings 5 of the first and second circulating parts 11 and 12 to generate the swirling flow in the fluid flowing through the flow passage 10. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
