Abstract
A magnetic liquid sealing device (100) with a heat conductive rod and a heat dissipating jacket includes: a shaft casing (1), a rotating shaft (2), two bearings (3), two pole shoes (4), a permanent magnet (5), a heat conductive rod (6) and a heat dissipating jacket (7). The rotating shaft (2) is rotatably arranged in the shaft casing (1), two bearings (3) and two pole shoes (4) are fitted over the rotating shaft (2), and the two pole shoes (4) are located between the two bearings (3). The permanent magnet (5) is fitted over the rotating shaft (2) and is located between the two pole shoes (4). The heat conductive rod (6) is inserted in the pole shoe (4), the heat dissipating jacket (7) is fitted over the shaft casing (2), and the heat conductive rod (6) is connected with the heat dissipating jacket (7) through a connecting member (11).
