Introduction

Microcomputer-based systems 1U chassis design has become the most used in servers, industrial electronics, information technology (IT) and telecommunications equipment Important internet. 1U chassis also sometimes referred to as "pizza box." 1U chassis applications has been widely extended, and solutions can be found in every area of \u200b\u200bthe electronics industry.

IEC 60297-3-100 specifies rack and cabinet size details, such as the available port and panel frame mounting dimensions. however, IEC 60297-3-100 for the 1U chassis with single or multiple (n × 1U laminate) assembled in a manner consistent with the GB/T 19520 of Rack, the rack, provide guidance or size requirements are inadequate.

This section carries the weight of 1U chassis, the physical dimensions and suitability to provide guidelines and size requirements.

According to the needs of the application, this section also provides different types of chassis.

Size allows the interface to develop universal mounting accessories for different types of chassis specified. Because of this particular case and the type of application the choice determines the selected 1U chassis airflow requirements and suitability can be made by the designer.

Similar property unit times the height of the device can be derived from this section. That the economic value of this part can be pre-applied to the development has been determined Set the chassis attachment interfaces size. In addition, due to the choice of installation support, but also indicates the possibility of cooling.
