Description

Technical Field

[0001] The utility model relates to the field of edge computing technology, and in particular to an industrial-grade passive heat dissipation edge computer based on a Jetson platform. Background Art

[0002] This section is intended to provide a background or context to the embodiments of the utility model recited in the claims. The description herein is not admitted to be prior art by inclusion in this section.

[0003] At present, edge computing technology has been implemented in many fields such as the Internet of Things and industrial control, and its application scenarios are becoming more and more abundant. Edge computing technology requires hardware with high computing power to carry it, so some processors or core modules that can accelerate algorithms have been produced in the market to meet the needs, such as the Jetson platform core modules launched by NVIDIA, such as Jetson Nano and Jetson Xavier NX. Traditional high-computing computers are large in size, such as computers with X86 architecture, which are too large and not easy to deploy on site. The Jetson platform core module launched by NVIDIA has the advantages of high computing power and small size, but it cannot work alone. It needs a matching carrier board to provide power and interface to work as a device. In addition, due to the large number of devices in the field of edge computing, various industrial equipment is required, such as cameras for data collection, display devices for human-computer exchange, RS485 buses for communication between devices, etc. A single device cannot take into account many interfaces. Because edge computers have high computing power and need to process many tasks, they consume a lot of power and generate serious heat, and they need to dissipate heat continuously to ensure the normal operation of the equipment. Traditional active heat dissipation, such as fans, is prone to noise due to mechanical structure limitations, and mechanical failures can cause the fan to stop rotating and heat dissipation to be untimely, causing the equipment to malfunction or even be damaged.
