Magnetic resonance imaging equipment

The invention discloses magnetic resonance imaging equipment. The equipment comprises a static magnetic field magnet (1), a gradient magnetic field coil (2) and an RF coil (3); the RF coil (3) and a cylindrical air duct shell (41) which is arranged on the inner side of the RF coil (3) limit air ducts (43); a sound insulation layer (42) is also arranged between the RF coil (3) and the air duct shell (41); the sound insulation layer (42) is used for separating the of air ducts(43); the air ducts (43) are communicated with a fan (7); at least one circuit element (5) is mounted on the area, corresponding to the air ducts (43), on the inner side face of the RF coil (3); the fan (7) comprises a motor and a control device, the motor drives a blade to supply air to the air ducts (43), and the control device can control the rotation speed of the motor according to the temperature in the air ducts (43). The magnetic resonance imaging equipment monitors the temperature in the air ducts so that the temperature condition
