On one hand, compared with the traditional electric heating mode, the electromagnetic reaction heating has higher heat conversion rate and is more efficient and energy-saving; on the other hand, the arrangement of the heating pipe 30 on the outer wall of the induction coil 20 facilitates the connection with the pipe in which the fluid to be heated is located.
Here, the fluid inlet 31 and the fluid outlet 32 of the heating pipe 30 may be connected in series to the flow pipe of the fluid to be heated through pipe joints, or connected in parallel to the flow pipe of the fluid to be heated. When the heating pipeline 30 is connected in series to a flowing pipeline of the fluid to be heated, the fluid flowing through the heating pipeline can be heated or stopped by controlling the on-off of the power supply 21. When the heating pipeline 30 is connected in parallel to a flow pipeline of the fluid to be heated, the heating of part or all of the fluid entering the flow pipeline can be realized by controlling the flow rate of the fluid entering the heating pipeline 30.
By adopting the electromagnetic induction heating device provided by the embodiment of the present disclosure, the heating pipeline 30 is arranged close to or attached to the outer wall of the induction coil 20, and is connected with the flow pipeline of the fluid to be heated through the fluid inlet 31 and the fluid outlet 32, so that the electromagnetic induction heating device can be conveniently connected or detached. Meanwhile, when an electromagnetic heating process occurs between the induction coil 20 and the magnetizer 10, the heating pipeline 30 absorbs resistance heat generated by electromagnetic induction to heat, and compared with the arrangement of the heating pipeline 30 arranged in the induction coil 20, the heating pipeline 30 is arranged on the outer wall of the induction coil 20, so that the heat transfer contact area is increased, the stroke of fluid in the heating pipeline 30 is increased, and the heat conversion efficiency of the device is further improved.
