Abstract:: Abstract: The electromagnetic pulsating blood pump is made based on the principle of electromagnetic induction, and the long-term power-on work will cause the blood pump to heat up. The high temperature of the blood pump will damage the blood pump, and raise the temperature of the blood circulating in the pump, causing damages to the blood components or even life-threatening. Therefore, it is necessary to pay close attention to the temperature of the electromagnetic pulsating blood pump and analyze its temperature field. By analyzing the temperature field of the blood pump using the finite element analysis software, the working temperature of the blood pump can be observed intuitively. The simulation results show that when the electromagnetic pulsatiling blood pump is set to work for 1 h, the highest temperature of the blood pump which is 100.3℃ is found at the drive winding, and the temperature of the contact surface between the pump and the circulating blood at 37℃ does not change much, which is 37.5 ℃ at the highest. Therefore, electromagnetic pulsatiling blood pump will not cause damage to the blood components, but the drive winding needs to be cooled to avoid damages to the blood pump and affecting the circulating blood.
