The specific embodiment
Below in conjunction with accompanying drawing 1-9, the present invention is further elaborated:
In order to realize tongue and groove position 41, the protrusion position 42, two arranging at magnetic conductive metal outer 3 is protruded 42 of positions and is formed recessed groove 43, and processing technology is simple, and the recessed groove 43 of formation easily passes through thermal current.
Tongue and groove Wei41 of the present invention cross section is quadrangle or arch or triangle or combination trapezoidal or herringbone or above shape, as a preferred embodiment, the recessed groove 43 of this real tongue and groove position 41 be arch with, protruding Wei42 cross section is quadrangle, in order to make air current flow smooth and easy, the arcuation setting in outside, the bottom of a pan, the tongue and groove Wei41Wei center of circle (the tongue and groove Wei center of circle of O Wei Yi guiding region, the Ru Tu2Zhong center of circle).
In order to reach good hot better effects, obtain by experiment, recessed groove 43 compares L with the width that protrudes position 42<sub TranNum="84">1</sub>/ L<sub TranNum="85">2</sub>for: 0.2<L<sub TranNum="86">1</sub>/ L<sub TranNum="87">2</sub><3, recessed groove 43 is d with the difference in height of protruding position 42, and during 0.2mm<d<10mm, heat conduction efficiency is higher.
The manufacturing process of composite pan bottom of the present invention, mainly comprises following processing step:
A, spot welding connect: the sheet material of stainless steel inner container layer 1, heat-conducting metal interlayer 2, magnetic conductive metal skin 3 is arranged in order, and anchor point is welded into composite board;
