Abstract: Methods and systems are provided for cooling hot spots on a body coil assembly of an MRI system. In one embodiment, an airflow guide of a body coil assembly of an MRI system comprises a first surface that forms an air passage when the airflow guide is positioned on the body coil assembly, the air passage enclosed by the first surface and a second, outer surface of an RF coil of the body coil assembly, the airflow guide configured to channel cool air generated by a fan to the second, outer surface of the RF coil. The airflow guide may be arranged circumferentially around a portion of the RF coil at one or more ends of the RF coil. The airflow guide may be manufactured as a plurality of airflow guide segments that are glued together.

Abstract: A method for fault diagnosis and a computer device are provided. The method is applied to a battery management system of the energy storage system and includes the following. A first thermal-runaway parameter detected by a first detection apparatus and a second thermal-runaway parameter detected by a second detection apparatus are obtained. A difference between the first thermal-runaway parameter and the second thermal-runaway parameter is calculated. Determine that at least one of the first detection apparatus or the second detection apparatus fails, when the difference is greater than a difference threshold. Determine that a battery module fails, when the first thermal-runaway parameter is greater than a first threshold, the second thermal-runaway parameter is greater than a second threshold, and the difference is less than or equal to the difference threshold.

Abstract: A method for remotely solving thermal runaway and related products are provided in implementations of the disclosure. The method is applied to a user terminal in a system for remotely solving thermal runaway, and include the following. At least one monitoring datum transmitted by at least one monitoring terminal and related to at least one energy-storage device is received at a preset frequency. When at least one of the at least one monitoring datum is greater than a threshold, an energy-storage device related to the at least one of the at least one monitoring datum is determined as a target energy-storage device. An accident type of the target energy-storage device is determined according to the at least one of the at least one monitoring datum, a first prompt message is generated, and the first prompt message is presented to a user in multiple manners.
