In the description of the invention, it is to be understood that term " " center ", " on ", " under ", "front", "rear", " left side ",
The orientation or position relationship of the instruction such as " right side ", " vertical ", " level ", " top ", " bottom ", " interior ", " outer " are based on shown in the drawings
Orientation or position relationship, be for only for ease of the description present invention and simplify description, rather than instruction or imply signified device or
Element must have specific orientation, with specific azimuth configuration and operation, therefore be not considered as limiting the invention.
In the description of the invention, it is necessary to illustrate, unless otherwise clearly defined and limited, term " installation ", " phase
Even ", " connection " should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected, or be integrally connected；Can
It to be to be joined directly together, can also be indirectly connected by intermediary, can be the connection of two element internals.For this area
For those of ordinary skill, the concrete meaning of above-mentioned term in the present invention can be understood with concrete condition.
As shown in figure 1, the invention provides a kind of electric heater unit, the electric heater unit includes can shape in the energized state
Into the conductor 101 of closed circuit, the alternation body of alternating magnetic field can be produced when circulation alternating current is provided with the conductor 101
102, when the alternation body 102 connects alternating current, electromagnetic induction occurs for the conductor 101 can make the conductor 101 to produce
The induced-current of heating.
Pass through above-mentioned technical proposal, when circulating alternating current on alternation body, the magnetic flux in conductor constantly changes, so as to
Produce induced electromotive force and induced-current, the faradic direction such as vortex of the circumferencial direction along conductor are turn-taked, therefore in conductor
Inside occur electromagnetic induction and produce induced-current, the electric current can make conductor temp.-elevating, so as to conduct heat to warmware to be added
On realize auxiliary electrical heater.This kind of mode of heating, heat conduction efficiency is added, effectively heat exchange can be achieved at a lower temperature,
