Abstract
The invention provides a liquid-cooled permanent magnet coupler. The liquid-cooled permanent magnet coupler comprises two groups of magnetic disks which are arranged oppositely. Conductive disks are compressed tightly on the opposite surfaces of the magnetic disks through a mould pressing technology. The surfaces, close to the magnetic disks, of the conductive disks are provided with cooling liquid flow channels, liquid grooves, liquid inlet holes and liquid outlet holes are formed in the magnetic disks, the liquid grooves are communicated with the liquid inlet holes, cooling liquid enters the liquid inlet holes under the effect of centrifugal force after entering the liquid grooves though a cooling oil pipe, and the liquid inlet holes and the liquid outlet holes are communicated with the cooling liquid flow channels. Through the liquid-cooled permanent magnet coupler, heat generated on the conductive disks by eddy currents can be taken away timely, the temperature of the conductive disks and the temperature of the magnetic disks can be controlled to be at a low degree, and magnets are not prone to demagnetization. Thus, noise generated when equipment runs is reduced.
