The invention relates to a self-adjusting rotor used for conveying blood or conveying shear sensitive fluid. The rotor rotates in a pump body so that the pressure of the fluid is increased and the fluid flows out along the circumferential direction relative to the flowing direction of a medium, the flowing direction comprises an incident flow face (3) and a back flow face (4), and an upper end face and a lower end face of the rotor are an upper oblique plane and a lower oblique plane; if the rotor is cut along a central axis, an included angle formed by an intersecting line of the upper oblique plane and a section and a rotary horizontal plane is an upper top angle beta, and the beta is more than 0 degree; an included angle formed by an intersecting line of the lower oblique plane and thesection and the rotary horizontal plane is a lower bottom angle alpha, and the alpha is more than or equal to 0 degree; the number of the rotors is even, and the rotors are symmetrically distributed along a rotating shaft; and rotor clearances are formed between the upper end face and the lower end face of the rotor and the pump body, the rotor clearances are the distances from each point on the upper end face and the lower end face to the inner surface of the corresponding pump body, and the rotor clearances from the incident flow face to the back flow face are reduced progressively. The self-adjusting rotor has extremely high self-balancing and self-adjusting properties. When the self-adjusting rotor is applied to an artificial heart, the rotor can reduce the damage to blood corpuscles,improve the compatibility with the blood, and lower the manufacturing cost.

A method for controlling a temperature of a terminal and a terminal supporting the same are provided. A terminal supporting temperature control includes a temperature sensor for detecting a temperature of the terminal, and a controller for performing at least one of a first throttle procedure including driving the controller with a first preset driving frequency when the temperature of the terminal detected by the temperature sensor is a first preset temperature, and driving the controller with a second driving frequency higher than the first driving frequency when the temperature of the terminal is reduced to a second preset temperature lower than the first preset temperature, and a second throttle procedure including driving the controller with the first preset driving frequency for a first time, and driving the controller with the second driving frequency higher than the first driving frequency for a second time after the first time elapses.

The invention discloses a self-suspending artificial heart. A rotor rotates in a pump body, so fluid is boosted to flow outside along the circumferential direction. The self-suspending artificial heart is characterized in that: the rotor consists of blades of even number; the blades are symmetrically distributed in an axial direction; the blades are connected and fixed by connecting rods; each blade has an approximately cylindrical shape; each blade comprises a flow-receiving surface and a back surface in the flow direction of a medium; and under the condition that the included angles betweenthe upper and lower end surfaces of the rotor and the rotary horizontal plane are more than 0 degree and the condition that the included angle, namely a lower bottom angle, between the lower end surface and the rotary horizontal plane is more than or equal to 0 degree, the clearances between the upper and lower end surfaces of the rotor and the rotor of the pump body decrease progressively from the flow-receiving surface to the back surface. The self-suspending artificial heart has extremely high self-balance and self-adjustment characteristics, can effectively reduce damages to the blood andthe formation of thromboses in the artificial heart, strengthen compatibility with the blood, reduce the manufacturing cost, improve the balance of the action forces applied by the blood in the artificial heart onto the rotor in different directions and improve the stability and safety of the rotor in operation.
