Fluid-structure interaction activation method under strong magnetic field and heat exchange device

The invention relates to the technical field of magnetohydrodynamic force and enhanced heat exchange, in particular to a fluid-structure interaction activation method under a high-intensity magnetic field and a heat exchange device.The activation method comprises the following steps that a heat exchange flow channel is arranged, conductive fluid is injected into the heat exchange flow channel, and the arrangement direction of the heat exchange flow channel is perpendicular to the direction of an external magnetic field; a fluid-solid coupling module is arranged in a heat exchange flow channel and specifically comprises a first electrode column and a flexible component, the first electrode column penetrates through the interior of the heat exchange flow channel, the two ends of the first electrode column make contact with air outside the heat exchange flow channel, and the arrangement direction of the first electrode column is the same as the direction of an external magnetic field. One end of the flexible mem
