Description of the Invention: [Technical Field] The present invention relates to a chassis-type diversion structure of a multi-embedded function board, and more particularly to a diversion structure that can quickly guide airflow to assist heat dissipation of a function board. The cold air entering the outside of the chassis is guided by the deflector, and the inside of the casing is circulated to dissipate the hot air from the exhaust area, and the airflow is prevented from flowing around to generate noise. [Prior Art] According to the innovation and progress of the technology era, various electronic products such as desktop computers, notebook computers, palm-sized computers or notebooks have become commonplace in the society. The expansion of various peripheral products enables electronic products to carry out more types of detection and control. With the vigorous development of the electronic technology industry, the traditional industrial technology in the past dominates the development of industrial control, testing and automation. Such as: programmable control (p L c) and various types of fie Id bus, but the speed and stability of the central processor (cpu) from & Intel, and Microsoft's (Microsoft) operating system Widely adopted, so that the function of pc is no longer only the ship's function and data processing, the promotion of pc technology, so that the specifications of various types of computer industry are constantly being updated, such as p I c computer specifications, pure man The fine PC/1 〇4 + specification, the birth of the p CI specification, the current p and P XI/C〇mpact 201016122 χ ϊ system has been widely and successfully applied in manufacturing test, automotive test, semiconductor Test, the machine supervision, functional test, military and aerospace industry applications above. PXI (PCI extensions f〇r Instrumentatuon) was developed in 1977 and published in 1989. It is available in the open industry standard and can meet the ever-increasing demands of complex instrument control systems. A solid PC-based platform with PXI combined with P CI power bus features

Compa c tPCI's rugged, modular and Eurcard package 'and then added a specialized synchronous bus and important software features, is a high-performance and low-cost deployment platform that provides measurement and automation systems. And can be via a program controller (pc), a laptop or

Express Card MXI or PCMCIA C a r d B u s interface tool set, and control the ρχ j system with a notebook computer.
