Benefits of technology

The present disclosure relates to a heat-dissipation system for preventing damage to a fan caused by inrush current. The technical effect of the invention is to provide a system that can prevent the fan from disengaging from the shell of a server when it is not shut down, which can lead to damage. The system includes a shell, a fan, a latch, and a micro-switch. The latch is designed to engage with the fan and prevent it from disengaging from the shell. The micro-switch is set on the inner surface of the latch and is turned on when the latch is engaged with the mounting plate, making contact with the fan. The system also includes a heat-dissipation system that includes a shell, a fan, a latch, and a micro-switch. The fan includes a first connector and a second connector, with signal pins and a live line pin used to transmit signals between a motherboard and the fan. The invention provides a solution to prevent damage to fans caused by inrush current and ensure the fan remains securely in place when not in use.

Problems solved by technology

If the server is not shut down, inrush current may cause damage to the fan.

Embodiment Construction

[0010]The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.” The reference “a plurality of” means “at least two.”

[0011]FIGS. 1-3 show an embodiment of a heat-dissipation system of the present disclosure.

[0012]The heat-dissipation system comprises a shell 10, a fan 12, a latch 16, and a micro-switch 18.

[0013]The shell 10 includes a rectangular backplane 100, two side plates 106 extending down from opposite sides of the backplane 100, and two substantially parallel mounting plates 102 extending down from the backplane 100. The mounting plates 102 are connected between the side plates 106. Each of the side plates 106 defines a vent 108. The vents 108 of the side plates 106 are in alignment with each other....

Abstract

A heat-dissipation system includes a shell, a fan, a latch, and a micro-switch. The fan includes a first connector and a second connector. The first connector includes a number of signal pins, a zero line pin, and a live line pin. The signal pins are used to transmit signals between a motherboard and the fan. The zero line pin and the live line pin are connected to a power supply. The zero line pin of the first connector is connected to a zero line pin of the second connector. When the latch is engaged with the shell, the micro-switch is turned on and the power supply supplies power to the second connector through the micro-switch and the zero and live line pins of the first connector. When the latch is not engaged with the shell, the micro-switch is turned off and the power supply is disconnected from the second connector.

Description

BACKGROUND[0001]1. Technical Field[0002]The present disclosure relates to heat-dissipation systems, and particularly relates to a heat-dissipation system for preventing inrush current of a fan.[0003]2. Description of Related Art[0004]To replace a damaged fan from a server, users should first shut down the server. If the server is not shut down, inrush current may cause damage to the fan.[0005]Therefore, there is room for improvement in the art.BRIEF DESCRIPTION OF THE DRAWINGS[0006]Many aspects of the present disclosure can be better understood with reference to the following drawing(s). The components in the drawing(s) are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawing(s), like reference numerals designate corresponding parts throughout the several views.[0007]FIG. 1 is an assembled, isometric view of an embodiment of a heat-dissipation system.[0008]FIG. 2 is an inverted,...
