ELECTROMAGNETIC INDUCTION HEATER

A heating device for heating underground soil comprising a conductor housed in a conductive casing, wherein when at least one driving current is supplied to the conductor, the conductor generates at least one magnetic field that induces at least one induced current in the casing. The driving currents are of a frequency sufficient to cause the induced currents to generate resistance in the casing,thereby increasing the temperature of the casing. A plurality of the heating devices may be arranged in an array to facilitate the heating of a zone of soil. 用于加热地下土壤的加热设备，包括：容纳在导电外壳中的导体，其中当至少个驱动电流被供应到导体时，导体产生至少个磁场，其在外壳中感应出至少个感应电流。驱动电流具有足以使感应电流在外壳中产生电阻的频率，从而增加外壳的温度。多个加热设备可布置在阵列中以便于土壤区域的加热。
