[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 The utility model provides a capacitor temperature control device of an eddy current drive mechanism, which is used to control the temperature of a capacitor 1, comprising:

[0024] A temperature detection module 3, used to detect the temperature of the capacitor 1 in the eddy current drive mechanism;

[0026] The control module 4 is connected to the temperature detection module 3 and the silicone heating plate 2 , and is used to dynamically adjust the power of the silicone heating plate 2 according to the temperature signal detected by the temperature detection module 3 .

[0027] In this embodiment, the temperature of the capacitor 1 is detected by the temperature detection module 3, and the power of the silicone heating plate 2 is dynamically adjusted to ensure that the capacitor 1 operates within a suitable temperature range, thereby achieving precise control of the temperature of the capacitor in the eddy current drive mechanism, ensuring that it operates within the optimal temperature range, extending the service life of the capacitor, and improving the overall reliability and energy efficiency of the equipment.

[0028] In one embodiment, the temperature detection module 3 includes at least one temperature sensor, and the temperature sensor is arranged on the surface or around the capacitor 1. This arrangement can accurately detect the temperature of the capacitor 1.

[0029] In one embodiment, the control module 4 includes a processor and a power regulator. The processor receives the temperature signal from the temperature detection module and generates a control signal to adjust the power regulator to adjust the power supply of the silicone heating plate.

[0030] In one embodiment, the power regulator is a pulse width modulation controller, which is used to adjust the power output of the silicone heating plate 2 by pulse width modulation. Specifically, the processor generates a control signal to adjust the PWM controller according to a preset temperature range, thereby dynamically adjusting the power output of the silicone heating plate 2. In this way, the control module 4 can adjust the heating power in real time according to the actual temperature change of the capacitor 1 to ensure that the capacitor 1 always works within the optimal temperature range; when the temperature of the capacitor 1 is lower than the lower limit of the preset range, the processor generates a corresponding control signal to increase the heating power of the silicone heating plate 2 through the PWM controller; when the temperature of the capacitor 1 is higher than the upper limit of the preset range, the processor generates a corresponding control signal to reduce the heating power of the silicone heating plate 2 through the PWM controller, or turn off the heating plate when necessary.

[0031] In one embodiment, the control module 4 further includes a safety protection module, which is used to automatically shut down the silicone heating sheet 2 when the temperature of the capacitor 1 exceeds a safety threshold. This arrangement can prevent the capacitor 1 from being damaged by overheating.

[0032] In one embodiment, a display module is also included to display the current temperature of the capacitor 1 and the current power state of the silica gel heating sheet 2 in real time.

[0033] In one embodiment, the silica gel heating sheet 2 is evenly coated on the outside of the capacitor 1. This arrangement ensures uniform distribution of heat, thereby avoiding local overheating.

[0034] In one embodiment, the temperature detection module 3 and the control module 4 are integrated on a circuit board, which can simplify the overall structure and improve reliability.

[0035] In one embodiment, the eddy current drive mechanism includes a metal shell, and the capacitor 1 and the silicone heating sheet 2 are arranged in the metal shell. In this way, the metal shell acts as a heat conductor and can optimize the heat dissipation effect.
