Description

Technical Field

[0001] This utility model relates to the field of computer equipment technology, and in particular to an integrated multi-USB device remote access server chassis based on ARM architecture. Background Technology

[0002] This integrated multi-USB device remote access server chassis, based on the ARM architecture, is an innovative device that breaks away from the traditional x86+Windows architecture model. It uses a high-performance, low-power ARM processor as its main control core and runs a lightweight and deeply customized Linux operating system, enabling efficient USB device management, network communication, and remote access services.

[0003] Its key innovation lies in the use of a high-density USB integrated PCB board. This core component can directly integrate 16-port, 32-port, 48-port or even higher density USB host controllers and physical USB ports (Type-A / Type-C). These ports are connected to the ARM processor through onboard high-speed buses (such as USB 3.x, PCIe), fundamentally eliminating the need for multiple USB data cables connecting the dock and the host in traditional solutions, and solving the problem of messy wiring for multiple devices.

[0004] While integrated chassis designs offer significant advantages in space integration and device portability, they are extremely detrimental to heat dissipation. To ensure a compact structure and the integration of multiple USB ports, the internal space of such chassis is extremely compact, leaving very little space for heat dissipation channels and hindering effective airflow. In addition, multiple USB devices generate additional heat during operation, further increasing the overall heat load inside the chassis. Problems such as unreasonable airflow design and insufficient cooling fan power combine to make it difficult for heat to be dissipated quickly from inside the chassis, resulting in prolonged high-temperature conditions that seriously affect the stability and lifespan of the server. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing integrated chassis designs, such as insufficient cooling fan power, which makes it difficult to dissipate heat quickly from inside the chassis, resulting in prolonged high temperatures and severely impacting the stability and lifespan of the server. The proposed invention is an integrated multi-USB device remote access server chassis based on the ARM architecture.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An integrated multi-USB device remote access server chassis based on ARM architecture includes an outer shell and a heat dissipation component installed inside the outer shell. A PCB board is fixedly installed inside the outer shell in a suspended manner. A power supply for powering the devices is fixedly installed on the left side inside the outer shell. A group of USB ports is opened on the front of the outer wall of the outer shell. An indicator light board is also fixedly installed on the left side of the USB port group. A gigabit Ethernet port is fixedly connected to the back of the outer wall of the outer shell. A power socket for powering the power supply is fixedly installed on the left side of the gigabit Ethernet port.

[0008] The heat dissipation assembly includes a small heat dissipation mesh opening on the back of the outer wall of the housing and a large heat dissipation mesh opening on both sides of the outer wall of the housing. A small cooling fan is fixedly installed inside the small heat dissipation mesh opening by bolts, and a water-cooling heat dissipation assembly is provided inside the large heat dissipation mesh opening.

[0009] Preferably, the water-cooled heat dissipation assembly includes a large cooling fan fixedly installed inside the large heat dissipation mesh, a heat sink fixedly installed at the air inlet end of the large cooling fan, a water pump connected through the outer wall of the heat sink, a circulating water pipe connected through the bottom of the heat sink, and a copper contact block connected through the end of the circulating water pipe away from the heat sink.

[0010] Preferably, the copper contact block is located below the PCB board, and two large heat dissipation fans are provided, both installed inside the large heat dissipation mesh.

[0011] Preferably, a flexible hose is fixedly connected to the output end of the water pump, and a small heat sink is connected through the flexible hose. The end of the flexible hose away from the water pump is connected through to the heat sink on the other side of the large cooling fan, and the small heat sink is installed on the back side of the small cooling fan.

[0012] Preferably, a telescopic rod is fixedly installed at the bottom of the copper sheet contact block, and a short screw is rotatably connected to the bottom center of the copper sheet contact block, with a fixing sleeve threaded onto the short screw.

[0013] Preferably, the top of the telescopic rod is fixedly connected to the inner wall of the housing, the bottom of the fixing sleeve is fixedly connected to the inner wall of the housing, and the short screw penetrates the outer wall of the housing.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. In use, this utility model employs a dual heat dissipation design—combining a small heat dissipation vent with a small cooling fan and a large heat dissipation vent with a water-cooling component—to form a three-dimensional and highly efficient heat dissipation system. In the water-cooling component, the copper contact blocks are directly attached to the PCB board, quickly absorbing heat generated by core components. This heat is then transferred to the heat sink via circulating water pipes, where a large cooling fan accelerates heat dissipation. Simultaneously, the small cooling fan helps dissipate residual heat from other areas inside the chassis, ensuring the overall chassis temperature remains within a reasonable range. This significantly improves server operational stability and extends the equipment's lifespan.

[0016] 2. In use, the PCB board inside the outer shell can be suspended, which reduces direct contact with other components. This reduces heat conduction interference and allows space for air circulation. The copper contact block can be height adjusted by telescopic rod and short screw. The contact tightness can be flexibly adjusted according to the actual thickness of the PCB board to ensure maximum heat conduction efficiency, reflecting the flexibility and humanization of the design.

[0023] Reference Figures 1-4 The integrated multi-USB device remote access server chassis based on ARM architecture includes a shell 1 and a heat dissipation component 8 installed inside the shell 1. The specific structure and connection relationship of each component are as follows:

[0024] The outer casing 1 serves as the load-bearing foundation of the entire chassis. Inside, a suspended PCB board 2 is fixedly mounted. This suspended configuration is achieved through a bracket (not shown in the diagram), reducing direct contact between the PCB board 2 and the outer casing 1 or other components. A power supply 3 is fixedly mounted on the left side inside the outer casing 1, providing power to all electrical devices within the chassis. A USB port group 4 is located on the front of the outer wall of the outer casing 1, containing multiple USB ports of various types to simultaneously connect multiple USB devices. An indicator light panel 5 is fixedly mounted on the left side of the USB port group 4, displaying power, operating status, and USB connection indicators to visually indicate the device's operating status. A gigabit Ethernet port 6 is fixedly connected to the back of the outer wall of the outer casing 1, providing a high-speed network channel for remote access. A power socket 7 is fixedly mounted to the left of the gigabit Ethernet port 6, connecting to an external power supply line to power the power supply 3.

[0025] The heat dissipation assembly 8 is one of the core components of this chassis, which includes a small heat dissipation mesh 9 on the back of the outer wall of the outer shell 1 and large heat dissipation mesh 10 on both sides of the outer wall of the outer shell 1. A small cooling fan (not specifically labeled in the figure) is bolted to the inside of the small heat dissipation mesh 9. The small cooling fan is compatible with the small heat dissipation mesh 9 and can accelerate the airflow inside the chassis. A water-cooling heat dissipation assembly is installed inside the large heat dissipation mesh 10 for efficient heat dissipation of the core components inside the chassis.

[0026] The specific structure of the water-cooled heat dissipation component is as follows: A large cooling fan 11 is fixedly installed inside the large heat dissipation mesh 10. In this embodiment, two large cooling fans 11 are provided and installed inside the large heat dissipation mesh 10 on both sides to enhance heat dissipation efficiency. A heat sink 12 is fixedly installed at the air inlet end of the large cooling fan 11. The heat sink 12 is provided with heat dissipation fins (not shown in the figure) to expand the heat dissipation area. A water pump 13 is connected through the outer wall of the heat sink 12, which provides power for the circulation of coolant. A circulating water pipe 14 is connected through the bottom of the heat sink 12. A copper contact block 15 is connected through the end of the circulating water pipe 14 away from the heat sink 12. The copper contact block 15 is located below the PCB board 2 and can directly contact the PCB board 2 to absorb heat.

[0027] Furthermore, a flexible hose (not shown in the figure) is fixedly connected to the output end of the water pump 13. A small heat sink 16 is connected through the hose. The small heat sink 16 is installed on the back side of the small cooling fan, and the airflow of the small cooling fan can be used to assist in heat dissipation. The end of the hose away from the water pump 13 is connected through to the heat sink 12 on the large cooling fan 11 on the other side, forming a complete coolant circulation loop.

[0028] To facilitate adjustment of the contact tightness between the copper contact block 15 and the PCB board 2, a telescopic rod 17 is fixedly installed at the bottom of the copper contact block 15, and the top of the telescopic rod 17 is fixedly connected to the inner wall of the outer casing 1. A short screw 18 is rotatably connected to the bottom center of the copper contact block 15, and a fixing sleeve 19 is threaded onto the short screw 18. The bottom of the fixing sleeve 19 is fixedly connected to the inner wall of the outer casing 1, and the short screw 18 penetrates through the outer wall of the outer casing 1. By rotating the short screw 18, the copper contact block 15 can be moved up and down under the action of the fixing sleeve 19, while the telescopic rod 17 ensures the stability of the copper contact block 15 during movement.

[0029] Working principle:

[0030] After the device is started, the power supply 3 connects to the power socket 7 and supplies power to all components; the heat generated by the PCB board 2 is transferred to the copper contact block 15, and the water pump 13 drives the coolant to flow in the loop composed of the circulating water pipe 14, the hose, the heat sink 12 and the small heat sink 16, carrying the heat to the heat sink 12 and the small heat sink 16; the large cooling fan 11 and the small cooling fan respectively provide air cooling for the heat sink 12 and the small heat sink 16, while accelerating the exchange of air between the inside of the chassis and the outside, achieving efficient heat dissipation; the contact state between the copper contact block 15 and the PCB board 2 can be adjusted by rotating the short screw 18 to ensure the heat dissipation effect; the USB port group 4 is used to connect external USB devices, the gigabit network port 6 enables remote access, and the indicator light panel 5 displays the device's working status in real time.
