Description

Technical Field

[0001] The utility model relates to the technical field related to capacitors, in particular to a high-voltage power LLC resonant capacitor. Background Art

[0002] Capacitors are one of the electronic components used in large quantities in electronic equipment, but the existing high-voltage power LLC resonant capacitors still have certain defects when used, such as;

[0003] For example, in a resonant capacitor with publication number CN208298701U, a thermally conductive insulating pad is arranged on the outer insulating layer on the upper surface of the electrode layer group, which is used to conduct the heat in the electrode layer group to the thermally conductive insulating pad, and then the thermally conductive insulating pad is cooled by a water-cooling plate in contact with the thermally conductive insulating pad, thereby playing the role of cooling the electrode layer group and ensuring that the resonant capacitor can work normally. In other embodiments, the thermally conductive insulating pad and the water-cooling plate can also be arranged on the lower surface of the electrode layer group to dissipate the heat of the electrode layer group. This embodiment is only an example of a situation and should not be regarded as a limitation on the scope of protection.

[0004] However, the resonant capacitor still has the following disadvantages in actual use:

[0005] The thermally conductive insulating pad is cooled by a water cooling plate in contact with the thermally conductive insulating pad. During actual use, the temperature of the water cooling plate is prone to uneven distribution, resulting in the thermally conductive insulating pad being cooled only in a part of the area, resulting in poor overall cooling effect. The whole cannot be adjusted according to the temperature, which reduces the overall service life. In addition, the water cooling plate requires maintenance operations, which not only increases the overall operating cost and complexity, but also increases the overall maintenance cost.

[0006] In view of the above problems, it is urgent to carry out innovative design based on the original high-voltage power LLC resonant capacitor. Therefore, we proposed that the high-voltage power LLC resonant capacitor can solve the above problems well. Utility Model Content

A heat dissipation port 14 is opened on the surface of the capacitor shell 1, and a dust cover 15 is installed on the outside of the heat dissipation port 14. A temperature detector 16 is arranged inside the capacitor shell 1. The capacitor shell 1 is connected to the outside through the outlet pipe sleeve 3 of the top plate 2, which is convenient for effectively connecting the capacitor and facilitating the use of the capacitor.
