The specific embodiment

The present invention adopts the following specific embodiment:

1, parts are prefabricated:

Spiral metal fin pipe: fin thermal conductor with holes outside fin high-frequency welding with holes is cast on seamless steel pipe or with the ferrimagnet essence.

Cross supporting frame: the smart casting of ferrimagnet, upper and lower cross supporting frame is measure-alike.

Connecting ring: the smart casting of ferrimagnet, upper and lower connecting ring is measure-alike.

Water jacket: heavy caliber adopts sheet material bending process or the smart casting of ferromagnetic material, small-bore employing back wall tube material.

More than the geometric parameter relation of three parts:

Spiral metal fin pipe height=water jacket height;

Connecting ring external diameter=water jacket external diameter, connecting ring internal diameter=water jacket internal diameter; Connecting ring height=3/2 times water jacket wall thickness;

Cross length=water jacket internal diameter+water jacket wall thickness;

Connecting ring depth of groove=cross width=cross thickness=water jacket wall thickness;

Ferromagnet: ferromagnetic material full circle post or assembly unit are equal.

The electromagnetism calandria: outside spreading insulating materials of ferromagnet or winding dielectric film, solenoid are wrapped in the outer back of ferromagnet and twine insulating barrier or spreading insulating barrier, and the lead-out wire location is drawn.

More than the geometric parameter relation of two parts:

Ferromagnet internal diameter=water jacket external diameter, ferromagnet thickness=1/2 water jacket wall thickness;

Ferromagnet height=water jacket height-2 times water jacket wall thickness;

Solenoid twines height＜ferromagnet height.

The UTILIZATION OF VESIDUAL HEAT IN water jacket: the metal material processing with shield electromagnetic signals becomes U type water jacket, and water pipe valve mounting interface is reserved in the bottom, and into water pipe valve mounting interface is reserved on top, suitable for readingly is connected into water jacket with U type bridge welding.
