Description

Power Supplier

The present invention relates to a power supply, and more particularly to a power supply having a fan and socket structure.

The power supply is an indispensable power supply device for electronic devices such as personal computers, industrial computers, servers, communication devices, or network devices, and can receive AC mains power and convert it into DC voltages of various specifications for use by the aforementioned electronic devices. . With the rapid development of the information industry and high-tech industry, the component integration in the power supply is rapidly increasing. In order to support the operation of a large number of components, the current rating of the power supply input socket of the power supply is bound to increase; and in order to maintain the normal operation of the component, the power supply also needs to have high heat dissipation performance, so that the components can be sufficiently dissipated. .

The C14 type socket is the power input socket commonly used in current power supply. However, the rated current of the C14 type socket is generally 10A, which limits the output power of the power supply and cannot provide higher output power to meet the application requirements. In addition, in some applications, such as server power supply, the width and height of the power supply have specific size limits, and the need for higher output power, thus the design, configuration and selection of the fan and socket of the power supply. More difficult. If the size of the power supply is increased to accommodate the larger size fan and socket, it will affect the overall configuration of the electronic device and increase the cost of re-production; if it is reduced to reduce the size of the fan, it will affect the heat dissipation of the power supply. The effect is that the power supply operates less or even fails to operate properly. If the socket with a larger rated current is selected, the socket size may be correspondingly increased, so that the size of the power supply housing is limited. It will make the configuration of the fan and the socket more difficult.

In view of this, it is necessary to develop a power supply to solve the problem that the conventional technology cannot maintain the power supply output while maintaining the output power of the power supply and ensuring the heat dissipation effect.

The purpose of the present invention is to provide a power supply that can accommodate a larger diameter fan and a higher rated current socket, which solves the problems faced by the prior art described above, is cost effective, and can maintain the power supply volume. Increase output power and heat dissipation performance under conditions.
