More specifically technical solution further includes：The lower groove is one kind of closed ring groove or spiral slot.
Further：The lower groove is segmentation arc groove.
Further：The lower groove is segmentation arc groove, and each section of connection is distributed on same Radius and forms ring-type
Structure.
Further：The upper groove of arc is provided with the lower surface of disk body, the upper groove is located at outermost layer heat-generating pipe half
Region in the range of footpath.
Further：The upper groove is one kind of closed ring groove or spiral slot.
Further：The upper groove is segmentation arc groove.
Further：The upper groove is segmentation arc groove, and first segment connection, which is distributed on same Radius, forms ring-type
Structure.
Further：The location interval that the disk body is located at recessed trench bottom is provided with threaded hole.
Further：The upper groove is located at the inner of lower groove or the outer end of lower groove.
It is an advantage of the invention that due to the recessing on disk body, when shrinkage thermal expansion, disk body can be deformed in groove,
To offset the deformation force of disk body, while keep the flatness of disc surfaces so that the heating object such as disc surfaces and pot body is protected
Good contact is held, improves the thermal efficiency, reduces electric loss of energy.
