In the figure, a hollow circular cooling plate 2 made of an aluminum plate, which is an excellent non-magnetic material, is pressure-welded to both sides of a circular coil 10, and a plurality of through holes 2a provided around the cooling plate 20 are used to press the cooling plate 2. A stud 3 with threads on both ends
The fastening method with Toto4 is adopted. Inside the cooling plate 2, there is a non-magnetic plate for circulating the cooling liquid multiple times along the circumference. A cooling pipe 5 made of a thin-walled steel pipe is buried, and before burying the cooling pipe 5 in the cooling plate 2, the cooling pipe 5 is
A method is adopted in which the shape and position of the aluminum are determined, and then the aluminum is cast with molten aluminum. However, since the melting temperature of aluminum material is as high as approximately 1000 degrees Celsius, during casting, the surface of the cooling tube 5 comes into contact with the molten aluminum material and an alloy metal is formed between the two metals, and when this becomes activated, a phenomenon called eutectic occurs. Therefore, in the case of thin-walled steel pipes, there is a risk of small holes being formed, and casting requires a mold and special equipment, making the equipment expensive.

る利点がある。FIG. 1 is an enlarged cross-sectional view of essential parts of an embodiment of a cooling device for a liquid-cooled coil according to the present invention. ing. In the figure, a cooling plate 2 made of an aluminum plate is provided with a U-shaped groove 2b having a semicircular base whose cross section is slightly larger than the diameter of a cooling pipe 5 made of a thin-walled steel pipe. A cooling pipe 5 coated with a filler 6 containing an adhesive mainly composed of powder of copper, aluminum, etc. with excellent magnetic properties is inserted over the entire outer circumference, and a groove 2b having a U-shaped cross section on one side is inserted into the cooling pipe 5. A presser strip 7 recessed in a semicircular shape similar to the bottom part of is fitted and welded. In this embodiment, the U-shaped groove is formed from only one side, but it goes without saying that it may be formed from both sides. The gap between the U-shaped groove 2b and the inner wall of the holding strip 7 and the cooling pipe 5, that is, the space filled with the filler 6, is 3 times larger than the particle size of the powder constituting the filler 6.
(By doing this, the presser foot 7
The filling material 6 is removed from the gap created between the U-shaped groove 2b and the opening of the U-shaped groove 2b.
Since the presser strip 7 and the opening of the U-shaped groove 2b do not come off, the presser strip 7 and the opening of the U-shaped groove 2b may be spot welded 8 within a range where the pressurized state of the presser strip 7 is maintained. Mutual heat exchange between cooling pipe 5 and cooling plate 2 is 9
As shown by the arrow, cooling is performed around the entire circumference of the cooling pipe 5, so there is no deterioration in cooling performance, and since no casting mold or casting equipment is required, the cost is reduced, and there are advantages in that the cooling pipe 5 does not need to be perforated.
