Embodiment 1

[0038] Such as figure 1 The electric heating sheet shown includes an insulating layer 3 and a heating element, and the insulating layer is usually made of polyimide, silica gel sheet, ceramic or mica material. The heating element is a heating conductor strip 1 formed by photochemical etching of an alloy heating foil, and the heating element is bonded on the insulating layer by high-temperature pressure bonding of an adhesive 4 .

[0039] The heating element is composed of two sections of heating conductor strips 1 repeatedly folded back and around in the plane. The specific winding method is that the first section of heating conductor strip 1 takes the first terminal 21 as the starting point, and circles back to the starting point in a square track in the counterclockwise direction. side and maintain a gap with the starting point to form a fifth coil 15 in the shape of an open square. The heating conductor bar 1 turns back to the outside of the fifth coil 15 at the end point of...

Embodiment 2

[0045] The difference between this embodiment and Embodiment 1 is that the width of the heating conductor strip 1 is the same, and the spacing of all the coils is also the same; or the width of the heating conductor strip 1 is not completely the same, and the spacing of all the coils is not completely the same; The width of the gradient is gradient, and the spacing of all coils is also gradient.

Embodiment 3

[0047] The difference between this embodiment and embodiment 1 or 2 or 3 is that the shape of the coil formed by the heating conductor bar 1 in a plane is circular, elliptical, rectangular or other symmetrical polygons.

Abstract

The invention belongs to the technical field of quantum sensors, particularly relates to an electric heating sheet capable of inhibiting a magnetic field and a design method, and solves the technical problem that an existing electric heating sheet for a nuclear magnetic resonance gyroscope generates a strong unrelated magnetic field. The electric heating sheet capable of inhibiting the magnetic field comprises insulation layers and a heating element, wherein the heating element is laminated and bonded between the insulation layers at the high temperature through an adhesive; and the heating element adopts a demagnetizing structure formed by repeatedly bending two sections of heating conductor bars in the plane. In addition, the invention provides the design method for the electric heating sheet. According to the electric heating sheet capable of inhibiting the magnetic field, the magnetic dipole moment demagnetizing effect of a current in a single layer is achieved through reasonable heating conductor arrangement at first and then the demagnetizing effect is further achieved through a dual-layer or multi-layer structure, so that the near-field magnetic field of the electric heating sheet is controlled to be in an extremely low level.

Description

technical field [0001] The invention belongs to the technical field of quantum sensing devices, and in particular relates to an electric heating sheet for suppressing a magnetic field and a design method thereof. Background technique [0002] The nuclear magnetic resonance gyroscope is an emerging sensing technology that obtains target information such as carrier rotation or environmental magnetic field by detecting one or several kinds of atomic nucleus information in the atomic ensemble. The nuclei of sensitive atoms used in NMR gyroscopes have at least one unpaired proton or neutron (that is, the atomic weight is odd, such as 129 Xe, 131 Xe, 21 Ne, etc.). The asymmetry of such nuclei makes the nuclei sensitive to magnetic fields. Therefore, the nuclear magnetic resonance gyroscope is sensitive to the influence of the magnetic field, and the change of the external irrelevant magnetic field will affect the accuracy of the nuclear magnetic resonance gyroscope. In order ...
