Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1, the electric machine cabin segment of the embodiment of the present invention includes an electric machine cabin segment casing 1 and an electric machine disposed in the electric machine cabin segment casing 1; the mounting end of the motor is connected with a mounting flange 10 and is mounted in the motor cabin shell 1 through the mounting flange 10.
The inner wall of the motor cabin section shell 1 is provided with a plurality of annular rib plates 9 so as to improve the supporting strength and prevent the motor cabin section shell 1 from being deformed due to large external impact.
The motor comprises a motor shell 2, a motor stator 3 and a motor rotor 4 which are matched with each other, a bearing 5 sleeved outside the motor rotor 4 and a plurality of memory alloy structures 6 arranged on the outer wall of the motor shell 2; in the embodiment, the motor shell 2 is provided with two circles of memory alloy structures 6; each circle is provided with 12 memory alloy structures 6 which are uniformly distributed along the circumferential direction of the motor shell 2; aiming at different motor sizes, when the number of mounting layers is considered, the mounting layers are arranged at equal intervals, and meanwhile, the whole quality is considered, so that the heat dissipation capacity can meet the requirement, and the motor is not required to be arranged too densely; according to the circumference equipartition rule, every layer of this embodiment is according to 30 installation interval equipartition arrangements, considers the extreme high operating mode that generates heat, and every layer can arrange more heat dissipation memory alloy structure 6 according to the equipartition to guarantee heat dissipation demand and radiating homogeneity.
One end of the single memory alloy structure 6 is a mounting end, and the other end is a free end; the mounting end is fixedly mounted on the outer wall of the motor shell 2 through a screw 7, and the free end is close to the inner wall of the motor cabin shell 1; the memory temperature of the memory alloy structure 6 is within the normal working temperature range of the surface of the motor; when the temperature in the motor cabin section shell 1 is lower than the memory temperature of the memory alloy structure 6, the free end of the memory alloy structure 6 is bent; after the temperature in the motor cabin section shell 1 reaches the memory temperature, the free end of the memory alloy structure 6 can be unfolded, and the size of the unfolded memory alloy structure can meet the requirement of contacting with the inner wall of the motor cabin section shell 1.
The tail end of the free end of each memory alloy structure 6 is coated with heat-conducting silica gel 8, so that efficient heat conduction between the memory alloy structures 6 and the motor cabin section shell 1 is facilitated. The invention has no special requirement on the bending form of the free end of the memory alloy structure 6, but in order to ensure the installation requirement and the heat dissipation requirement, under the condition that the initial installation does not touch the annular ribbed plate 9, the bending part of the memory alloy structure should be as close as possible to the inner surface of the motor cabin section shell 1, so that when being heated, the memory alloy structure can be rapidly unfolded to form a heat transfer passage to lead out the heat generated by the motor.
The principle of the invention is as follows:
before the motor starts to work, the free end of each memory alloy structure 6 is bent; after the motor starts to work, heat generated by the motor rotating at a high speed is gathered to raise the temperature in the motor cabin shell 1, when the temperature in the motor cabin shell 1 reaches the memory temperature of the memory alloy structure 6, the free end of the memory alloy structure 6 deforms and expands, the heat-conducting silica gel 8 at the tail end of the heat-conducting silica gel is in contact with the inner wall of the motor cabin section shell 1, a heat bridge is established, and the heat generated by the motor rotating at a high speed is led out.
