Abstract

The invention discloses a heat dissipation type electromagnetic coil device and electromagnetic physiotherapy equipment thereof. The electromagnetic coil device comprises a hollow framework, a coil is wound on a supporting wall on the side face of the framework, a magnetic core composed of a plurality of magnetic needles arranged in a bundle shape is arranged in the hollow portion of the framework, and a plurality of heat dissipation holes are formed in the supporting wall of the framework. Cooling air passes through the heat dissipation holes. The electromagnetic coil device aims to solve the problems that an existing electromagnetic coil device is poor in heat dissipation, too much heat is transferred to a magnetic core through a coil, the temperature of the magnetic core is increased, and the magnetic field intensity is insufficient.

Description

technical field [0001] The invention belongs to the field of medical and health care equipment, in particular to a heat dissipation electromagnetic coil device and electromagnetic physiotherapy equipment thereof. Background technique [0002] At present, the known electromagnetic coil device is composed of a coil frame, a coil and a magnetic core. When the electromagnetic physiotherapy equipment performs physiotherapy on the human body, in order to enhance the physiotherapy effect, the general electromagnetic coil device will be as close to the human body as possible, so that the magnetic field generated by the electromagnetic coil can have the greatest effect on the human body. However, since the electromagnetic coil generates heat when it is energized, when the human body is treated for a long time, the heat generated by the electromagnetic coil will be conducted to the magnetic core, and the temperature of the magnetic core will rise. If the electromagnetic coil performs ...
