Embodiment Construction

[0033] In order to make the purpose, technical solution and advantages of the present invention clearer, the specific structure, principle and structural optimization process of the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0034] The present invention proposes and designs a constant-temperature uniform magnetic field generating device using double-circuit liquid cooling. In order to generate a uniform magnetic field in the horizontal direction, such as figure 1 As shown, a pair of identical coils are required to be placed coaxially with the distance between their centers equal to the radius of the coils. When the two coils are supplied with current in the same direction, the superposition of the magnetic field is enhanced, and an approximately uniform magnetic field is formed in a certain area; the total magnetic field can be given by the following formula near the mid...

Abstract

The invention discloses a constant-temperature uniform magnetic field generator using two-loop liquid cooling, in particular to a uniaxial magnetic field generator capable of generating a magnetic field with high uniformity and strength as high as hundreds of gauss magnitude orders. Simultaneously, the constant temperature in an ordinary uniform magnetic field is maintained, and the generator can be applied to biomedicine, electronic equipment and magnetic field experiments of chemical and functional materials. Compared with an ordinary uniform magnetic field, the maximum working magnetic field is improved, so that the uniform magnetic field strength reaches more than 500 gauss, and the temperature is constant during long-term usage. The system structure is simple, the two loops work independently in an inner circulation and outer circulation mode, outlets and inlets are pipe joints of G1 / 4 specifications, and accordingly, the connection and the detachment are facilitated.

Description

technical field [0001] The present invention proposes a constant-temperature uniform magnetic field generating device using double-circuit liquid cooling, and particularly relates to a single-axis magnetic field generating device capable of generating relatively high uniformity and strength of hundreds of gauss orders of magnitude, while maintaining a constant temperature in the uniform magnetic field space , can be used in magnetic field experiments in biomedicine, electronic equipment, chemistry and functional materials. Background technique [0002] A typical uniaxial uniform magnetic field generating device is composed of two coils with the same number of coil turns, the same coil winding method, and the coil radius is equal to the coil spacing. It is a device that produces a uniform magnetic field in a small area [Document 1. Wang Sen, Luo Cheng. Uniformity Analysis of Helmholtz Coil Magnetic Field. University Physics. vol. 17, pp. 17-19, 1998.]. Because the structural...
