Description

Technical Field

[0001] This utility model relates to the field of switch cabinet technology, specifically a switch cabinet for improving the heat dissipation efficiency of a switch. Background Technology

[0002] A switch (also known as a switching hub) is a network device used for forwarding electrical (optical) signals. It can provide a dedicated electrical signal path for any two network nodes connected to the switch. A network needs to use multiple switches, which requires organizing and collecting the switches and storing them in storage cabinets. However, multiple switches generate a lot of heat when in use, and commonly used storage cabinets cannot provide timely heat dissipation for every location where the switches are stored.

[0003] A search revealed that patent CN221264334U discloses a heat dissipation cabinet for storing switches. It is equipped with a heat dissipation fan, a through slot, and a guide pipe. The air outlet of the heat dissipation fan is located in the through slot, which injects external air into the slot. Once the through slot is filled with air, it is discharged through the guide pipe. External air enters each cavity inside the cabinet through the guide pipe, accelerating the air circulation inside the cavity and quickly dissipating the heat inside the cabinet through the exhaust box. The dust cover on the heat dissipation fan can trap dust particles in the external air.

[0004] While the above solution can improve the ventilation efficiency of the server rack by using cooling fans, thereby improving the heat dissipation efficiency of the internal switches, and can reduce the amount of dust entering the server rack by setting up dust covers, the dust covers cannot completely prevent the entry of external dust. After long-term use, a large amount of dust will still accumulate inside the server rack, and the dust covers need to be cleaned regularly, which is quite troublesome.

[0005] A search revealed that patent CN220896791U discloses an industrial switch cooling cabinet. This cabinet, with its cabinet body, water-cooled shell, and fan shell, allows for layered installation of switches within the cabinet using mounting brackets. Heat generated during switch operation is dissipated through the outer shell. A pressurized water pipe is connected via an inlet valve, and a water tank via an outlet valve. Pressurized water is circulated through the water pipes to each water-cooled shell, cooling its outer shell. Simultaneously, the water-cooled shell exchanges heat with the surrounding air for initial cooling. Simultaneously, a cooling fan draws in outside air and blows it into the fan shell. This outside air is then blown through the outlet onto the outer wall of the water-cooled shell, further cooling the outside air. The outside air is then blown between the switches, accelerating the flow of hot air between them. This allows the hot air inside the cooling cabinet to be expelled through the exhaust vents, accelerating airflow around the switches and achieving efficient air cooling to ensure long-term stable operation of the switches.

[0006] Although the above solution can achieve a certain water cooling effect through the use of structures such as water-cooled shells and circulating water pipes, the cooling effect is not good due to the small heat exchange area of ​​the water-cooled shell. In addition, the cabinet of this solution still needs to be connected to the outside air for air cooling, so dust accumulation still occurs inside the cabinet.

[0007] In addition, the space and location for placing the switches in the above scheme are fixed, which is inconvenient for users to deploy according to their actual usage. Therefore, we propose a switch cabinet to improve the heat dissipation efficiency of the switches. Utility Model Content
