Description

V. New description: [New technical field] A centrifugal heat dissipation structure and a motor with a centrifugal heat dissipation structure, especially a centrifugal fluid generated by rotation to increase the vapor-liquid circulation inside the heat dissipation structure, thereby greatly improving the heat dissipation of the motor The performance of the centrifugal heat dissipation structure and its motor. [Prior Art] The current motor and generator and all kinds of motors are driven by the rotor and the stator to induce electric power or power generation. When the silicon steel sheet placed on the rotor is energized around the outer coil, heat will be generated. The magnetic hysteresis loss (iron loss) and the copper loss generate thermal power of the rotor cause the temperature rise of the motor rotor, reduce the efficiency, and limit the maximum power of such a rotating electric machine. Motors typically have an efficiency of about 85%. A 15% loss in the motor causes the motor winding, the motor stator and/or the heat of the housing of the motor. When operating at atmospheric pressure, the heat generated in the rotor of the motor is mainly transmitted to the outer casing of the motor by convection (using air in the motor as a medium for transfer from the motor rotor to the motor casing). The motor rotor can be provided with a cooling fin to maximize this effect. Although some of the heat loss power is also transmitted to the outside via conduction and radiation along the motor or generator shaft and via the bearings, these heat transfer mechanisms only produce relatively small cooling effects. When the high-speed shaft and the hot rotor are operated under high temperature conditions, the rotor is required to be cooled, and the side rotor is burnt due to the thermal power generated by the magnetic hysteresis (iron loss) and copper loss when the side rotor is operated under high load conditions. . The motor and generator cooling systems currently used are mainly used for heat dissipation only for the stator, and there is no effective heat dissipation method for the rotor design, so the rotor cannot be effectively cooled. Therefore, the prior art has the following disadvantages: 1. The magnetic hysteresis loss of the rotor _ loss generates heat transfer thermostatic temperature rise, limited motor power; 2. The rotor structure is easy to accumulate heat; 3. The rotor cooling performance is low. [New content] In order to solve the above-mentioned shortcomings of the prior art, the main purpose of the present invention is to provide a centrifugal heat dissipation structure for increasing the temperature of the heat-dissipating shaft portion through centrifugal force. The secondary objective of this creation is to provide a motor with a centrifugal heat dissipation structure. For the purpose of the above, the present invention provides a centrifugal heat dissipation structure, comprising: a body having a shaft hole and a heat absorption zone and a heat transfer zone, wherein one end of the heat transfer zone is connected to the heat absorption zone, and the other end is connected to the shaft hole Connected, the shaft hole extends axially through the body.
