Description

Technical Field

[0001] The utility model relates to the technical field of capacitors, in particular to a sealed shell of a liquid-cooled capacitor. Background Art

[0002] A capacitor is two conductors close to each other with a layer of non-conductive insulating medium in between. When voltage is applied between the two plates of the capacitor, the capacitor will store charge. In the prior art, liquid-cooled capacitors are used to improve the heat dissipation effect of the capacitor during operation. Liquid-cooled capacitors need to be connected to a liquid cooling head. Since the liquid cooling channel needs to be arranged inside the liquid cooling head, it is necessary to ensure the sealing of the liquid cooling channel. Most of the existing methods use friction welding or plugging to seal the liquid cooling channel, and the sealing effect is poor. Utility Model Content

[0003] In view of the defects in the prior art, the purpose of the utility model is to provide a sealed housing for a liquid-cooled capacitor, which can improve the sealing performance of the liquid-cooling flow channel of the capacitor housing.

[0004] The technical solution adopted by the utility model is: a sealed shell of a liquid-cooled capacitor, comprising a shell body, a cooling groove is provided at the upper end of the shell body, liquid cooling heads are provided at both ends of the shell body, and a cooling flow channel communicated with the cooling groove is provided in the liquid cooling head; a sealing port is provided on the side of the liquid cooling head away from the shell body, the sealing port is riveted with a sealing head, the front end of the sealing head is provided with an assembly section that is inserted into the sealing port, and the rear end is provided with a riveting section, the inner side of the riveting section is provided with riveting serrations arranged around the assembly section, and one end of the assembly section close to the riveting section is provided with a circumferentially arranged conical guide groove.

[0005] In the present technical solution, the liquid cooling heads installed at both ends of the shell body seal the sealing port through the sealing head, thereby ensuring the sealing of the cooling channel. The sealing head adopts a riveted structure, and the assembly section is inserted into the sealing port. The sealing port is squeezed by the riveted serrations to cause plastic deformation around the circumference of the riveted serrations, and the deformed part is guided by the conical guide groove, thereby generating a seal and locking with the opening area of ​​the sealing port, preventing the sealing head from falling off and improving the sealing effect.

[0006] Preferably, the sealing opening is provided with circumferentially arranged rivet grooves.

[0007] Preferably, a mounting hole is provided at the upper end of the shell body corresponding to the outer side of the cooling groove.

[0008] Preferably, diagonally arranged positioning columns are provided on the upper end of the shell body.

[0009] The beneficial effect of the utility model is that the liquid cooling heads located at both ends of the shell body in the utility model seal the sealing port through the sealing head to ensure the sealing of the cooling channel. The sealing head adopts a riveting structure, and uses the riveting saw teeth to extrude the sealing port, so that the riveting saw teeth produce plastic deformation around the circumference, and the deformed part is guided by the conical guide groove, thereby producing a sealing lock with the opening area of ​​the sealing port, preventing the sealing head from falling off and improving the sealing effect, which has a high practical value.
