Abstract: The disclosure provides a network equipment power supply and a heat dissipation system therefor. The heat dissipation system includes a liquid-cooling heat dissipation device and an air-cooling heat dissipation device. The liquid-cooling heat dissipation device includes a liquid inlet, a liquid outlet, and a liquid-cooling pipe between them, wherein liquid-cooling medium flows inside the liquid-cooling pipe and takes away heat generated by components arranged around the liquid-cooling pipe; The air-cooling heat dissipation device includes an air inlet, an air outlet, and an air-cooling channel between them, wherein airflow passes through the air-cooling channel and takes away heat generated by components arranged around the air-cooling channel. The disclosure conducts hybrid heat dissipation combining characteristics of liquid-cooling heat dissipation and air-cooling heat dissipation to effectively enhance heat dissipation efficiency, and provides a new choice for design of a power supply unit with high power density.

Abstract: A power supply device includes an outer casing, a fan and a wire. Wherein the outer casing has four sides, wherein two adjacent ones of the four sides intersect, thus forming four corners. A central axis of which being parallel to an extending direction of the outer casing, and the fan being placed in the outer casing to divide the power supply device into a first part and a second part. The fan includes a fan frame having three positioning holes adjacent to any three of the four corners of the outer casing, wherein the fan frame has no positioning hole adjacent to the remaining corner of the four corners of the outer casing which forms a reserved space. The wire is connected to the second part from the first part of the power supply device through the reserved space.
