Embodiment Construction

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] The present invention provides a low-power, compact, normal-temperature Bitter-type strong magnet, whose structure is shown in 6, including a magnet body and an electrical pure iron 10 serving as a magnetic yoke. The structure of the magnet body is as Figure 4 , Figure 5 As shown, it is composed of 16 turns of coaxial coils with the same inner diameter and different outer diameters stacked together, and the magnet body. It can be seen from the following magnetic field formula and ohmic loss formula that when the inner diameter is the same, the larger the outer diameter, the smaller the magnetic induction intensity and the smaller the power consumption. Therefore, the combination of different outer diameters can obtain a longer uniform region of the magnetic field while reducing the power consumption required to obtain the length of th...

Abstract

The invention belongs to the technical field of high-intensity magnetic fields, and particularly relates to a low-power-consumption compact normal-temperature Bitter type strong magnet. The invention provides a low-power-consumption compact normal-temperature Bitter type strong magnet which is based on the characteristic that heating of a Bitter coil is in a trend of decreasing from inside to outside. When each turn of coil is assembled, the radius of the inner circle of the cover plate is designed to be larger than that of the inner circle of the annular structure, so that the central area of the coil is not covered. After the magnet is assembled, the whole central area forms a hollow structure, so that a transverse heat dissipation channel is constructed, most joule heat is taken away, the heat dissipation performance is improved, and the magnet can work continuously. Compared with a mode that liquid flows in aligned axial holes to take away generated joule heat, the low-power-consumption compact normal-temperature Bitter type strong magnet provided by the invention has the advantages that heat can be quickly dissipated, the structure is simple and compact, the power consumption is low, and the practicability is high.

Description

technical field [0001] The invention belongs to the technical field of strong magnetic fields, in particular to a low power consumption compact normal temperature Bitter type strong magnet, which is especially suitable for gyrotron and nuclear magnetic resonance imaging. Background technique [0002] Both gyrotron and MRI require a uniform strong magnetic field. Currently, commonly used strong magnetic field systems include permanent magnets, pulsed magnets, normal temperature resistance magnets and superconducting magnets. Permanent magnets are the most convenient to use, but the size and weight of permanent magnets are huge and cannot be miniaturized. Superconducting magnets have an absolute advantage in applications that require ultra-high magnetic fields because of their ability to generate ultra-high magnetic fields. However, superconducting magnets are expensive and need to work in 3-4K ultra-low temperature environments and require a long cooling time. Therefore, when...
