Abstract

The invention relates to a charger shell of a switching power supply, and is suitable for chargers with different powers and special heat sink sections. The charger shell comprises a left and a right shell type heat sink sections, a display end cover, a cover plate, a fan end cover and a bottom plate, wherein the left and the right shell type heat sink sections respectively comprise a heat sink section body, a power device mounting surface, inner cooling fins, outer cooling fins, a cover plate fitting surface, a bottom plate fitting surface and a base; two sides of the heat sink section body are respectively provided with the inner cooling fins and the outer cooling fins; the inner side of the heat sink section body is provided with the power device mounting surface; the bottom of the heat sink section body is provided with the base; the left and the right shell type heat sink sections are respectively arranged at the left and right sides of the charger shell of the switching power supply; the cover plate is fixed on the cover plate fitting surface at the upper part of the heat sink section body by screws; the bottom plate is fixed on the bottom plate fitting surface at the bottom of the heat sink section body by screws; and the two sides of the left and the right shell type heat sink sections are respectively provided with the display end cover and the fan end cover.

Description

technical field [0001] The invention relates to a switching power supply charger shell, which is suitable for chargers of different powers and special radiator profiles. Background technique [0002] At present, the traditional charger adopts linear power supply technology, which is composed of a linear transformer and a rectifier device, which is large in size and low in efficiency. Due to the wide variety and specifications, the requirements for the charger shell are often a headache in charger design. Chargers with different powers have very strict requirements on the volume of the charger shell. The power is different, and the current passing through the power device is different; the larger the current, the larger the radiator and the shell are required, and the power of the charger is closely related to the shell volume. [0003] The new-generation charger adopts switching power supply technology, which is small in size and high in efficiency. The switching power supp...
