Water-cooled magnetic coupler of spiral water channels

Abstract

The invention discloses a water-cooled magnetic coupler of spiral water channels. The spiral water channels are formed in a copper plate and a copper plate steel frame, finally the spiral water channels are composed of the copper plate and a copper plate end cap, and the spiral water channels are designed by Archimedes helix. The water channels with regular Archimedes helix are easy to process, the waterways of three helix water channels are uniformly distributed, and the heat dissipation effect is uniformly good. A cooling mechanism is arranged in a mechanism body itself, it is not necessaryto arrange a shell additionally to withstand the gravity of a water tank, so that equipment is not overweighed; a heat dissipation mechanism is not additionally arranged, so that the mechanism is simplified. The waterways are sealed in the water tank, excessive contact with other parts is avoided, and corrosion to the equipment can be reduced. A water inlet of the copper plate steel frame is formed near the center position of the copper plate, a water outlet is formed in the outer circle position of the copper plate steel frame, and in the high speed rotation process of the magnetic coupler, the centrifugal force facilitates the circulation of the cooling water.

Description

Technical field [0001] The invention relates to the technical field of machinery, in particular to a spiral water tank water-cooled magnetic coupling. Background technique [0002] During the working process of the magnetic coupler, the eddy current field on the copper plate causes the copper plate to generate heat, which causes the temperature of the magnetic coupler to rise. When the magnetic coupling is in a high temperature state for a long time, the permanent magnet (neodymium iron boron material) will be irreversibly demagnetized, causing the magnetic coupling to fail to work normally. Generally, the heat dissipation of small and medium-power magnetic couplers is mainly through the heat exchange between the surface of the magnetic coupler parts and the surrounding air; however, as the transmission power of the magnetic coupler increases, the temperature rise will become more serious and the heat dissipation The problem is more prominent. The air heat dissipation is not eno...

AI Technical Summary

Problems solved by technology

The cooling scheme requires a relatively large shell to bear the water tank, which makes the equipment bulky, and the additional heat dissipation system also makes the structure more complicated, and the cooling water is in direct contact with the internal parts of the equipment for a long time, making the equipment more prone to corrosion
