Abstract

The utility model discloses a shell structure of a charge pump, which relates to the technical field of charge pumps and comprises a lower shell, an upper shell and pins, the upper shell is mounted on the lower shell, the pins are mounted on two sides of the upper shell, and side combined heat dissipation structures are arranged on four side surfaces of the lower shell. Through mutual cooperation of the side combined heat dissipation structure, the upper combined heat dissipation structure, the side heat conduction columns, the upper heat conduction columns, the lower shell heat conduction layer and the upper shell heat conduction layer, heat inside and outside the charge pump shell can be rapidly transferred, and heat generated in the charge pump can be rapidly conducted out in the operation process of the charge pump. In order to avoid influence on normal operation of the charge pump and shortening of the service life of the charge pump due to overhigh temperature of the charge pump, the bottom heat dissipation fin plate is arranged and can support the lower shell, so that a certain heat dissipation channel is reserved at the bottom of the lower shell, the bottom surface of the charge pump can effectively dissipate heat, and the service life of the charge pump is prolonged. And the heat dissipation efficiency of the charge pump is improved.
