Description

technical field [0001] The invention belongs to the technical field of nuclear reactor engineering heat transfer, and in particular relates to an alkali metal heat pipe driven auxiliary by an electromagnetic pump and a heat transfer method thereof. Background technique [0002] A heat pipe is a heat transfer element with high thermal conductivity and a closed heat transfer device that does not require external driving force. It relies on the capillary suction provided by the internal liquid-absorbing core to maintain the continuous circulation of the working fluid, and continuously transfer the heat from the hot end to the cold end. It has a series of advantages such as extremely high thermal conductivity, good isothermal property, and controllable temperature. For capillary-driven horizontal alkali metal heat pipes or anti-gravity alkali metal heat pipes, the way to strengthen capillary force is mainly to increase the number of liquid-absorbing cores of the heat pipe, but t...

Problems solved by technology

For capillary-driven horizontal alkali metal heat pipes or anti-gravity alkali metal heat pipes, the way to strengthen capillary force is mainly to increase the number of liquid-absorbing cores of the heat pipe, but the method of increasing the number of liquid-absorbing cores to strengthen the driving force of backflow is in the prior art. There are process limitations in the process and the cost is high
