Embodiments of the present invention provide a magnetron phase change heat storage device and method, wherein the device includes a tank body, a heat transfer mechanism, a temperature sensor, a magnetic field generator and a controller; the tank body is filled with a magnetic phase change material; the heat transfer mechanism Part of it passes through the tank; the temperature sensor is set in the tank; both the temperature sensor and the magnetic field generator are connected to the controller, and the controller is used to control the magnetic field generated by the magnetic field generator according to the temperature value inside the tank measured by the temperature sensor, so as to magnetize the magnetic field The magnetic phase change material can form a thermomagnetic convection effect, so that the magnetic phase change material can store or release energy during phase change, and then regulate the temperature inside the tank; it can accelerate or decelerate the process of thermal energy storage or release according to the instantaneous temperature difference. , so that the phase change energy storage has self-adaptive active control and expands the applicable working condition range. |
