Description

Technical Field

[0001] The present invention relates to the technical field of thermal management of network communication devices, and particularly to a multi-port intelligent switch. Background Art

[0002] With the rapid development of industrial Internet and data centers, as a core network node, multi-port intelligent switches are facing technical challenges such as a sharp increase in port density and a doubling of data processing load. In the prior art, air cooling is limited by the internal space of the device, and forced convection is difficult to penetrate the dense wire harness area. In traditional water cooling structures, due to the single pipeline layout and fixed water flow direction, heat accumulation is likely to occur at the end. At the same time, the lack of an embedded temperature control system leads to a lag in heat dissipation response and is difficult to match the dynamic load changes of the switch. In addition, factors such as dust and electromagnetic interference in industrial scenarios accelerate the aging of heat dissipation components, and frequent maintenance seriously affects the availability of the device. These defects severely restrict the deployment ability of multi-port devices in harsh environments such as 5G edge computing and intelligent manufacturing, and there is an urgent need to break through the existing bottlenecks through heat dissipation architecture innovation and intelligent control technology.

[0003] Traditional devices generally have two major bottlenecks during high-load operation:

[0004] First, the compact multi-port layout leads to a sharp increase in heat flux density. The conventional single-path heat dissipation design is prone to local hot spots, which may cause chip performance degradation or even downtime.

[0005] Second, existing heat dissipation solutions mostly use independent air cooling or simple water cooling modules, which are difficult to cooperate to cope with instantaneous heat shocks and environmental temperature changes. Problems such as a sharp drop in heat dissipation efficiency and condensation water accumulation are likely to occur under high-temperature, high-humidity or vibration conditions.

[0006] Therefore, a multi-port intelligent switch is proposed to solve the above problems of multi-interface heat dissipation. Summary of the Invention

[0007] (1) Technical Problems to be Solved

[0008] Aiming at the deficiencies of the prior art, the present invention provides a multi-port intelligent switch to solve the technical problem of multi-interface heat dissipation.

[0009] (2) Technical Solutions

[0010] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0011] A multi-port intelligent switch, comprising

[0012] Housing and port assembly. The housing is a detachable square box made of aluminum alloy. Four groups of support feet are provided at the bottom of the housing. The support feet are used to support the bottom of the housing, and the whole housing is lifted by the support feet to provide space for heat dissipation and ventilation at the bottom. A port assembly is provided at the tail of the housing, and multiple groups of exchange wire harnesses are installed through the port assembly.

[0013] Preferably, the port assembly includes a heat dissipation module. The heat dissipation module is made of aviation aluminum alloy material. An installation opening is provided in the middle of the heat dissipation module. The installation opening is a trapezoidal stepped block evenly distributed in several groups, and the socket is fixed through the installation opening.

[0014] Preferably, a first heat dissipation channel and a second heat dissipation channel are provided in the middle of the heat dissipation module. The first heat dissipation channel and the second heat dissipation channel are respectively water flow channels provided inside the heat dissipation module, and the heat generated during operation in the heat dissipation module is dissipated through the circulation of the channel water flow.

[0015] Preferably, the first heat dissipation channel and the second heat dissipation channel are designed in a loop structure, and the first heat dissipation channel and the second heat dissipation channel are staggered in the x-axis and z-axis directions. In addition, in the case of a lateral cross-section of the heat dissipation module, the first heat dissipation channel and the second heat dissipation channel are staggered in the y-axis direction, which can more evenly realize the uniform distribution of the horizontal plane and lateral space of the heat dissipation module and more evenly realize heat dissipation. A heat dissipation grille is provided at the upper end of the heat dissipation module. The heat dissipation grille is a grille structure vertically distributed, which increases the contact area with the air and further improves the heat dissipation level.

[0016] Preferably, a first water inlet pipe and a second water outlet pipe are provided on the right side of the port assembly, and a first water outlet pipe and a second water inlet pipe are provided on the left side of the port assembly. The second water outlet pipe and the second water inlet pipe are respectively connected to both ends of the first heat dissipation channel, and the first water inlet pipe and the first water outlet pipe are respectively connected to both ends of the second heat dissipation channel.

[0017] Preferably, the channel of the first heat dissipation channel is in the circulation direction of the second water inlet pipe for water inlet and the second water outlet pipe for water outlet, and the water flow channel of the second heat dissipation channel is in the circulation direction of the first water inlet pipe for water inlet and the first water outlet pipe for water outlet. The two first heat dissipation channels and the second heat dissipation channels are water flow paths in opposite directions, which can avoid the poor consistency of heat dissipation caused by the increasing water temperature due to the water flow, and better control the temperature of the port assembly within a reasonable range.

[0018] Preferably, a temperature detector is provided in the middle of the port assembly to measure the temperature inside the heat dissipation module, realize linkage with external temperature control equipment, and complete temperature monitoring and temperature control of the port assembly.

[0019] Preferably, flow meters are provided in the first water outlet pipe and the second water outlet pipe to monitor the flow rate in the pipeline, and combined with the water flow temperature of the temperature detector to achieve comprehensive adjustment of temperature control.

[0020] Preferably, filters are provided in the first water inlet pipe and the second water inlet pipe. The filters can filter the incoming water flow to prevent impurities from entering the first heat dissipation channel and the second heat dissipation channel, causing pipeline blockage and improving the service life.

[0021] Preferably, side air outlets are provided on both sides of the housing, and the side air outlets can be used for air-cooling heat dissipation of the electrical components inside the housing.

[0022] (III) Beneficial effects

The composite heat dissipation structure (water-cooling + air-cooling) improves the heat exchange efficiency. The three-dimensional uniform waterway improves the heat dissipation uniformity and avoids local overheating. The dual-channel redundancy design ensures a certain heat dissipation capacity even when a single channel fails. The filtration protection reduces the pipeline blockage rate.
