[0005] At present, the common practice in the industry for active cooling is to install a cooling fan. However, due to the particularity of industrial network equipment that cannot be shut down and needs to run for a long time, the active cooling of the fan has the following disadvantages: the fan works at full speed all the time. Waste and increase the noise of the whole machine, but also increase the load power consumption of the power supply, excessive accumulation of dust in the casing, etc.
Heat accumulation in the switch will quickly lead to a decrease in the performance of the switch, resulting in packet loss and downtime, until the device crashes

The application discloses an industrial switch with a graphite heat sink. The industrial switch is characterized in that a switch chip is provided with an aluminium-based heat sink, and the position, in contact with the switch chip, of the aluminium-based heat sink is hollowed; the cross section of the aluminium-based heat sink is U-shaped, and the aluminium-based heat sink is fixed on a mainboard of the switch; the graphite heat sink is arranged in a bottom groove of the U-shaped aluminium-based heat sink and above the switch chip and is pasted in the bottom groove of the aluminium-based heat sink and above the switch chip; heat of the switch chip is transferred onto the aluminium-based heat sink through the graphite heat sink. According to the application, the problem of overhigh temperature of a conventional industrial switch is solved by a heat dissipation system in which the graphite heat sink and the aluminium-based heat sink are combined, and the graphite heat sink can provide more excellent heat conduction and dissipation performance under the condition of reducing the device weight.
Description
technical field [0001] The invention relates to the field of industrial switches, in particular to an industrial switch provided with graphite heat sinks. Background technique [0002] Because the electromagnetic compatibility, temperature, humidity, and dustproof requirements of industrial sites are higher and harsher than those of ordinary environments, industrial switches generally need to meet the following requirements in R&D and design: industrial-grade wide temperature design, electromagnetic compatibility design, dual power supply wide voltage redundancy Yu design and PCBA do three-proof treatment, that is, moisture-proof, mildew-proof, and smoke-proof. [0003] Commercial switches are not designed to withstand harsh industrial sites, and do not have the ability to work in industrial environments for a long time. They are often prone to failures in industrial environments, and maintenance costs continue to rise. It is not recommended to use commercial grade switches ...
