计算机起火原因剖析

An Analysis of the Computer Fire Causes

随着计算机使用的普及,由计算机起火引起的火灾时有发生。总结出计算机容易引起火灾的部位有CPU、显示卡、笔记本电池、电源适配器等,而通常引发这些部件起火的原因为散热故障导致局部过热、线路老化电阻增大、电压不稳器件烧毁等,找出计算机的起火规律,为计算机引起火灾的调查提供参考。

Nowadays, with the significant development of science and technology, computers are widely used in all fields of society. This paper first describes the composition of the computer, and analyzes the characteristics of the parts that are liable to catch the fire such as the CPU, the display card, the laptop battery and the power adapter. Through the research and analysis of different cases, the causes of fires have been summarized. The common fire causes are the elimination of heat, the aging of wires, and the unstable voltage. Some suggestions are provided for the fire investigation in the future.
