**电脑机箱的内部构造及选择技巧** **一、电脑机箱的内部构造** 电脑机箱，也称为主机箱或塔式机箱，是电脑硬件的重要组成部分。其内部构造主要包括以下几个部分： 1. 主板托架：主板是电脑的核心，它被固定在主板托架上，托架为主板提供支撑并确保其稳定运行。 2. 电源供应单元：负责为电脑各部件提供稳定的电力。电源供应单元通常位于机箱的后部或底部。 3. 扩展槽：用于安装各种扩展卡，如显卡、声卡等。 4. 存储设备位：用于安装硬盘、固态驱动器等存储设备。 5. CPU插槽和散热系统：CPU是电脑的“大脑”，其安装在主板上的特定插槽中，并配有散热系统以确保其正常运行。 6. 内存插槽：用于安装内存条，提升电脑的运行速度和多任务处理能力。 7. 风扇和散热孔：帮助散热，防止电脑过热导致性能下降或损坏。 **二、选择电脑机箱的技巧** 1. 尺寸与结构：根据主板类型（如ATX、microATX等）选择合适尺寸的机箱。同时，考虑机箱的布局和结构是否有利于散热。

2. 材料与质量：机箱的材料应具有一定的韧性和防锈性，质量好的机箱能提供更好的保护和散热性能。 3. 扩展性：考虑机箱的扩展槽数量和类型，以便于未来升级硬件。 4. 散热性能：良好的散热系统对电脑的稳定运行至关重要。选择具有足够风扇和散热孔的机箱，并确保其散热系统设计合理。 5. 兼容性：确保机箱能兼容您计划使用的硬件组件，如电源、显卡等。 6. 价格与品牌：根据预算选择合适的品牌和型号，注意不要只看重价格而忽略了质量和售后服务。 **三、英文翻译** **Internal Structure and Selection Skills of Computer Chassis** The computer chassis, also known as the main case or tower case, is an important part of the computer hardware. Its internal structure mainly includes the following parts: 1. Motherboard tray: The motherboard, the core of the computer, is fixed on the motherboard tray, which provides support and ensures its stable operation. 2. Power supply unit: Responsible for providing a stable power supply for various components of the computer. The power supply unit is usually located at the back or bottom of the chassis. 3. Expansion slots: Used to install various expansion cards, such as graphics cards and sound cards.

4. Storage device position: Used to install storage devices such as hard drives and solid-state drives. 5. CPU slot and cooling system: The CPU is the "brain" of the computer, which is installed in a specific slot on the motherboard and equipped with a cooling system to ensure its normal operation. 6. Memory slot: Used to install memory sticks to improve the computer's running speed and multitasking ability. 7. Fans and ventilation holes: Help with heat dissipation to prevent the computer from overheating, leading to performance degradation or damage. **Skills for selecting a computer chassis**: 1. Size and structure: Choose a chassis with the right size based on the type of motherboard (such as ATX, microATX, etc.). At the same time, consider whether the layout and structure of the chassis are conducive to heat dissipation. 2. Material and quality: The material of the chassis should have a certain degree of toughness and rust resistance, and a good quality chassis can provide better protection and heat dissipation performance. 3. Expandability: Consider the number and types of expansion slots in the chassis for future hardware upgrades. 4. Heat dissipation performance: A good cooling system is crucial for the stable operation of the computer. Choose a chassis with enough fans and ventilation holes, and ensure that its cooling system design is reasonable.

5. Compatibility: Ensure that the chassis is compatible with the hardware components you plan to use, such as power supplies, graphics cards, etc.

6. Price and brand: Choose an appropriate brand and model based on your budget, remembering not to only focus on price but also on quality and after-sales service.
