Desktop computer power supply of high-temperature automatic-powering-off

Abstract

The invention discloses a desktop computer power supply of high-temperature automatic-powering-off. The power supply includes a power supply housing body. A power supply plug is fixedly mounted on oneend of the power supply housing body. A wiring terminal is fixedly connected with one end of the power plug. A protection tube is fixedly communicated with one end of the power supply plug. An innerwall of the protection tube is in fixed sleeve connection with an outer surface of the wiring terminal. One end of the power supply housing body is provided with air inlets. A heat dissipation fan isfixedly mounted on an inner wall of the other end of the power supply housing body. The inner wall of the other end of the power supply housing body is provided with air outlets. According to the desktop computer power supply of high-temperature automatic-powering-off, an effect of using a principle of expansion with heat and contraction with cold to disconnect the power supply is achieved; when aheat dissipating device in the power supply is damaged, alcohol absorbs heat, then expands, and pushes sliding rods, and the sliding rods drive spring pieces on a surface of a fixing plate to slide to be disconnected from electrical connection of the wiring terminal; and thus the problem that after a long period of use of the heat dissipating device in the desktop computer power supply, the fan stops rotating, and then the power supply is liable to be damaged is effectively solved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a desktop computer power supply with high-temperature automatic power-off. Background technique [0002] The application of computers is becoming more and more common in China. After the reform and opening up, the number of computer users in China has continued to rise, and the application level has continued to improve. In particular, applications in the fields of Internet, communication, and multimedia have achieved good results. From 1996 to 2009, the number of computer users increased from 6.3 million to 67.1 million, and the number of networked computers increased from 29,000 to 59.4 million. Internet users have reached 316 million, and wireless Internet users have reached 670 million mobile users, of which 117 million are mobile Internet users, ranking first in the world. [0003] At present, the power supply used in desktop computers will be equipped with a cooling devi...
