Drawer-type double-sided electromagnetic heating system

Abstract

The invention provides a drawer-type bilateral electromagnetic heat-generating system and belongs to the technical field of electric heating. The drawer-type bilateral electromagnetic heat-generatingsystem comprises heating water tanks, an electromagnetic coil, a drawer-type assembly, a magnetizing coil, a frequency variable ultrasonic energy converter and the like, each heating water tank is ofa flat rectangle structure, and the electromagnetic coil is arranged between the two adjacent heating water tanks. Bilateral heat generation is achieved while water electric separation is conducted, the electromagnetic heat generation area and the electromagnetic coil utilization rate are effectively increased, and electromagnetic radiation is reduced. Through the combined structure of the heatingwater tank and the drawer-type assembly, production and mounting are quite facilitated, and hotline overhaul and maintenance can be achieved. Through scale prevention of the magnetizing coil and thescale removing effect of the frequency variable ultrasonic energy converter, the service life of the system is effectively prolonged, the efficiency of the system is effectively improved, additionallythe drawer-type bilateral electromagnetic heat-generating system further has the advantages that the production cost is low, the technique is simple, capacity increasing is convenient, the size is small, the operation cost is low, the energy saving effect is remarkable, and safety and reliability are achieved, and can be widely applied to various electric heating occasions, and the energy savingand environment protection effects are effectively improved.

Description

Technical field[0001]The invention relates to an electromagnetic heating system, in particular to a high-power electromagnetic heating system adopting a drawer type structure and heating on both sides. It belongs to the field of electric heating technology.Background technique[0002]The principle of electromagnetic intermediate frequency heating is currently very mature. Generally, two main methods are used in application. One is to wind the electromagnetic coil on the heated body, and the other is to place the heated body on one side of the disk electromagnetic coil. Its common feature is that compared with the heating coil, it is heated on one side, and the heating area is less than 50%. The other side needs to be equipped with a magnetic material and a thermal insulation layer, which will cause a certain amount of heat loss and cause more electromagnetic waves. radiation. Each power model is independently designed and manufactured, the production process is complicated, the materi...
