DETAILED DESCRIPTION OF THE INVENTION

[0015] FIG. 1 (a) is a perspective view of a coolant channel structure cooling high-power isolator according to the present invention, and FIG. 1 (b) is a cross-sectional view perpendicular to the line A-A of (a). The drawing shows a waveguide-type right-angle isolator, but is not limited thereto, and can be applied to all high-output devices such as a Y-tube type isolator.

[0016] FIG. 1 is an embodiment of a coolant channel structure cooling high-power isolator 1, the main configuration of which is that a ferrite 60 is installed inside a junction of a waveguide, a permanent magnet 70 is installed in an external groove, and a water-cooled cooling device 10 having a water channel structure is installed on top of the permanent magnet, and the components are formed in a vertical symmetrical pair.

[0017] The ferrite is a magnetic material that strengthens the induced magnetic field of the permanent magnet, and the ferrite for high output is formed in a large area, so manufacturing cost is high, processing is difficult, and damage or breakage may be caused by thermal strain.

[0018] A conventional cooling is water-cooled by installing a cooling water pipe made of a pipe around a permanent magnet from the outside of the waveguide. The ferrite was indirectly cooled by local cooling by installing a water pipe around it, so that the cooling was not uniform and the cooling efficiency was not high.

[0019] In order to solve the above problems, the present invention installs a cooling device 10 having a structure of a water channel 30 in a spiral form on the upper part of the permanent magnet and the surface of the waveguide.

[0020] As shown in FIG. 2 (a), the cooling water injected into a water inlet 11 flows along a spiral channel groove 31 that forms the water channel of the cooling device, cools the lower part, and rotates in reverse at the central part and is discharged to an outlet 12.

[0021] FIG. 2 (b) is a cross-sectional view showing a cross-sectional view perpendicular to line B-B, in which a channel groove 31 of a spiral structure is formed, an O-ring groove 21 for inserting an O-ring to prevent water leakage is formed, and a cover 50 is covered and fixed to a coupling port 40 with a screw or the like.

[0022] The water-cooled cooling device of the water-channel structure according to the present invention completely covers an area that cannot be covered by the conventional water-pipe structure and the cooling water flows in a spiral, so the cooling efficiency is remarkably superior.

[0023] In another embodiment of the present invention, it is possible to form a water channel directly in the main body of a isolator and cover a cover without removing a cooling device as shown in FIG. 3.
