Aluminum Stamped Case & Shell for Switching Power Supplies

Stamped power supply aluminum shell is a common type of power supply shell. Compared with traditional steel shell, the weight of aluminum shell is greatly reduced. In some occasions where there are requirements for equipment weight, such as power supply applications in portable electronic devices, aerospace and other fields, it has obvious advantages and is easy to carry and install.

5052 aluminum plate has good ductility and plasticity, and is easy to process into power supply shells of various shapes and sizes to meet different design requirements. Its strength and rigidity are high, which can withstand a certain degree of external impact and pressure and protect internal components. It also has excellent corrosion resistance and can adapt to a variety of environmental conditions, especially humid or corrosive environments, and can maintain stable appearance and performance for a long time. In addition, the aluminum plate has good thermal conductivity, which helps to quickly dissipate the heat inside the power supply and prevent the components from being degraded or damaged due to overheating.

6061 aluminum alloy has high strength and good processing performance, and can be made into power supply shells of complex shapes through stamping process. It also has good corrosion resistance and can be used in different environments. At the same time, 6061 aluminum alloy has strong weld-ability, which is convenient for some welding processing on the shell, such as adding fixings.

The stamped power supply aluminum shell is usually designed with heat dissipation holes, heat dissipation fins and other structures to increase the heat dissipation area, improve the heat dissipation efficiency, ensure that the heat generated by the power supply during operation can be dissipated in time, and maintain the normal operating temperature of the power supply. Considering the electromagnetic compatibility of the power supply during operation, the electromagnetic shielding effect can be enhanced by reasonably designing the shell structure and selecting suitable materials to prevent internal electromagnetic signals from interfering with external devices, while avoiding external electromagnetic interference from affecting the normal operation of the internal circuit of the power supply. The stamped power supply shell is designed with mounting holes, mounting slots, etc., which are convenient for fixing the power supply on the corresponding equipment or bracket. The reserved power cord interface, output interface and other openings are reasonably located and precisely sized, which is convenient for cable plugging and unplugging, and can protect the interface and surrounding components.
