Description

[0001] The utility model relates to the technical field of permanent magnet speed regulators, in particular to a cooling component of a permanent magnet speed regulator. Background Art

[0002] Permanent magnet speed regulation is an upgraded product of eddy current permanent magnet coupling transmission. Its simple structure, reliable operation, energy saving and consumption reduction features are well applied in modern industry. It is mainly used in energy saving of motor drive systems in industries such as petroleum, petrochemical, electric power, mining, steel, chemical, cement, etc.

[0003] In the prior art, a permanent magnet speed regulator proposed in patent application number "CN201420175739.1" includes a separate and coaxial first shaft and a second shaft, wherein the first shaft is provided with an annular permanent magnet turntable, the second shaft is provided with an annular shaft sleeve, the shaft sleeve is provided with a cylindrical inner sleeve, and the inner sleeve is provided with an annular conductor turntable at the edge near the first shaft.

[0004] However, in the above patent, the eddy current generated by magnetic induction generates huge heat, and the original structure's forced air cooling has limited effect on heat dissipation, which can easily cause the permanent magnet coupler to burn out due to high temperature, reducing the service life of the permanent magnet speed regulator. The high-temperature liquid inside the permanent magnet speed regulator continuously impacts and rubs the inner wall of the permanent magnet speed regulator shell under the action of centrifugal force, causing serious erosion and corrosion of the inner shell of the permanent magnet speed regulator.
