[0025] As Figures 1-4As shown, the bottom of the heat plate 34 is fixed with an insulating plate 35, and the heat conduction heat storage plate 36 is fixed at the bottom of the insulating plate 35, which is convenient to insulate the current in the insulating connecting frame 31 and conduct heat to the heated object, avoids the loss of heat, and improves the heating effect and efficiency. A plurality of pipe openings 2 are formed in the heating base plate 1 for adding cold water, so that when the heating of the heated object is stopped, cold water is added to the pipe openings 2 to quickly cool the spiral heating wire 32.

[0026] By setting the heat conduction assembly 3, the spiral heating wire 32 is made of red copper pipe, and the plug-in port 37 is connected, so that the high-frequency large current flows to the spiral heating wire 32. Thus, a strong magnetic flux with a polar instantaneous change is generated in the spiral heating wire 32. The metal and other heated objects are placed on the top of the heat conduction heat storage plate 36, and the magnetic flux will penetrate the entire heated object. In the interior of the heated object, a large eddy current corresponding to the opposite direction of the heating current will be generated.

It also has excellent moisture resistance, shock resistance, corona resistance, leakage resistance and chemical medium resistance. It can be used continuously at -60~280℃ and maintain performance. It does not swell and has good adhesion to most metals and non-metallic materials. The heat conduction glue can quickly conduct the heat in the heat plate 34 to the heat conduction heat storage plate 36, and conduct and store heat in the heat conduction heat storage plate 36, so as to avoid heat loss and improve the heat conduction rate and heating effect.
