A high temperature resistant industrial Ethernet switch

Abstract

The invention discloses a high-temperature-resistant industrial Ethernet switch, which comprises a metal shell, a metal sequin is fixedly installed on the upper end surface of the metal shell, a glass panel is fixedly installed on the metal sequin, and a glass panel is fixedly installed inside the metal shell. There is a circuit substrate, a heat dissipation pipe is attached to the circuit substrate, a flexible circuit board is attached to the heat dissipation pipe, a thermoelectric power generation mechanism is installed on the flexible circuit board, and the side of the metal shell is symmetrically embedded and installed There are two metal dust-proof nets, and an air-cooling heat dissipation mechanism is installed on the inner wall of the metal casing. The invention reduces radiant heat conduction through glass panels and metal sequins, increases the heat resistance of the device, and achieves the purpose of automatically adjusting the heat dissipation speed according to the temperature situation through the air-cooled heat dissipation mechanism and the temperature difference power generation mechanism. It does not need an independent power supply, reduces energy consumption, and is flexible. The circuit board can be better attached to the heat pipe for heat dissipation, increasing the heat dissipation capacity of the device.

Description

technical field [0001] The invention relates to the field of industrial switches, in particular to a high temperature resistant industrial Ethernet switch. Background technique [0002] Industrial Ethernet switches, that is, Ethernet switch devices used in the field of industrial control, due to the openness and wide application of the network standards adopted, most industrial Ethernet switches are used in open air places with high temperature or in transfer control rooms. However, due to the small area and infrequent use of these areas, air conditioners and other equipment are generally not installed to cool down. Therefore, industrial Ethernet switches must have a high temperature resistance to ensure that the temperature rises sharply under sunlight in high temperature summer Still able to work stably. [0003] At present, the best solution for improving the heat resistance of industrial Ethernet switches is the heat dissipation solution, which reduces the temperature o...

AI Technical Summary

Problems solved by technology

[0005] 1. The fan-type convective heat dissipation structure needs continuous operation during the heat dissipation process, resulting in unnecessary waste of electric energy;

[0006] 2. When the water flow evaporates and cools the metal shell, a lot of water resources are wasted, and cooling down with water for a long time will easily cause the metal shell to rust and cause the internal electronic components to be damaged by moisture;

[0007] 3. Only use a liquid cooler to cool down in circulation, which is not suitable for cooling down in the overall high temperature and harsh environment where the industrial Ethernet switch is located
