Description

Technical Field

[0001] This utility model relates to the field of gateway device technology, and specifically to an SDN-based smart gateway. Background Technology

[0002] With the widespread adoption of the internet and the development of wireless technology, SDN-based smart gateways have become indispensable electronic devices in modern homes and businesses. However, as gateway device performance improves, power consumption also increases, leading to increasingly prominent heat generation issues. Under prolonged high-load operation, the internal temperature of the casing rises, affecting not only performance stability but also potentially shortening device lifespan and even causing malfunctions.

[0003] Most SDN-based smart gateways on the market currently use materials with good thermal conductivity, such as PC / ABS alloy, for their casings and enhance airflow through ventilation holes and slots to dissipate heat. However, these heat dissipation methods are still insufficient when faced with the high power consumption of the high-performance gateway itself. Utility Model Content

[0004] To address the technical problems existing in the prior art, this application provides an SDN-based smart gateway.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: an SDN-based smart gateway, comprising: a gateway body, the gateway body having a housing and an SDN controller disposed within the housing, the housing also having memory, an interface and an antenna electrically connected to the SDN controller; a heat dissipation mechanism, the heat dissipation mechanism including a heat dissipation fan, a heat dissipation vent on the top of the housing, the heat dissipation fan disposed on the housing, the heat dissipation fan being disposed at the input end of the heat dissipation vent, the heat dissipation fan being connected to the SDN controller, a ventilation gap between the SDN controller and the bottom plate of the housing, and several air inlets on the bottom of the housing.

[0006] In some embodiments of this utility model, a support platform is provided on the housing, which is used to form a heat dissipation space with the SDN-based smart gateway on the desktop.

[0007] In some embodiments of this utility model, a rubber suction cup base is provided at the end of the support platform away from the housing.

[0008] In some embodiments of this utility model, the input port of the above-mentioned cooling fan is provided with a temperature measuring element, which is electrically connected to the SDN controller.

[0009] In some embodiments of this utility model, the housing is provided with an indicator light for displaying the working status of the cooling fan, and the indicator light is electrically connected to the SDN controller.

[0010] In some embodiments of this utility model, a dustproof net is provided on the air inlet, and the dustproof net is located inside the housing.

[0011] In some embodiments of this utility model, heat dissipation fins are provided on both sides of the housing.

[0012] Beneficial effects:

[0013] This invention provides an SDN-based intelligent gateway, comprising: a gateway body, which has a housing and an SDN controller disposed within the housing; the housing also has memory, an interface, and an antenna electrically connected to the SDN controller; and a heat dissipation mechanism, which includes a cooling fan, a heat dissipation vent on the top of the housing, the cooling fan mounted on the housing and at the input end of the heat dissipation vent, the cooling fan connected to the SDN controller, a ventilation gap between the SDN controller and the bottom plate of the housing, and several air inlets on the bottom of the housing. The gateway body is used to identify network addresses and select the optimal transmission path according to the routing table to transmit data from the source network to the target network. The gateway body can also connect multiple networks to achieve data transmission and communication between different networks. The SDN controller is the data processing core of the SDN-based intelligent gateway, responsible for executing various instructions and algorithms in the gateway body, including path selection calculation, routing information exchange, routing table lookup, and packet forwarding. When the gateway body receives data packets, it caches these data in memory until the processor has sufficient time to process them. This caching mechanism helps reduce processor waiting time and improves data processing efficiency. The aforementioned interface serves as a bridge connecting the SDN-based smart gateway to the external network. It receives signals from the external network and transmits them to the gateway itself for processing. The antenna is used for transmitting and receiving wireless signals; it converts broadband data streams into radio waves, sends them to surrounding devices, and receives signal requests from these devices, completing bidirectional data transmission. The cooling fan generates airflow to remove heat generated inside the gateway, thus lowering the device temperature. Maintaining the safe operating temperature of internal electronic components such as the processor and chipset is crucial. High temperatures can degrade the performance of these components and even cause malfunctions. By effectively reducing the device temperature, the cooling fan helps maintain the stability and reliability of the gateway, extending its lifespan.

[0014] Therefore, this gateway body can quickly extract high-temperature gas from the bottom up, greatly improving its working performance and extending the service life of the equipment. Attached Figure Description

[0026] Example

[0027] Please refer to Figures 1-3 This embodiment provides an SDN-based smart gateway, including: a gateway body, the gateway body having a housing 1 and an SDN controller 2 disposed within the housing 1, the housing 1 also having a memory 3, an interface 4 and an antenna 5 electrically connected to the SDN controller 2; a heat dissipation mechanism, the heat dissipation mechanism including a heat dissipation fan 7, a heat dissipation vent 6 opened on the top of the housing 1, the heat dissipation fan 7 disposed on the housing 1, the heat dissipation fan 7 disposed at the input end of the heat dissipation vent 6, the heat dissipation fan 7 being connected to the SDN controller 2, a ventilation gap 8 between the SDN controller 2 and the bottom plate of the housing 1, and a plurality of air inlets 9 opened on the bottom of the housing 1.

[0028] In this embodiment, the SDN controller 2 is the data processing core of the SDN-based smart gateway, responsible for executing various instructions and algorithms within the gateway, including path selection calculation, routing information exchange, routing table lookup, and packet forwarding. When the gateway receives a data packet, it caches this data in memory 3 until the processor has sufficient time to process it. This caching mechanism helps reduce processor waiting time and improves data processing efficiency. The interface 4 is the bridge connecting the SDN-based smart gateway to the external network. It is responsible for receiving signals from the external network and transmitting them to the gateway for processing. The antenna 5 is used for transmitting and receiving wireless signals. It can convert broadband data streams into radio waves, send them to surrounding devices, and receive signal requests from these devices, completing bidirectional data transmission.

[0029] In this embodiment, the aforementioned cooling fan 7 generates airflow to remove heat generated inside the gateway body, thereby reducing the device temperature. It is crucial that the electronic components inside the gateway body, such as the processor and chipset, operate within a safe temperature range. High temperatures can cause performance degradation of these internal electronic components and even lead to malfunctions. By effectively reducing the device temperature, the cooling fan 7 helps maintain the stability and reliability of the gateway body and extends its lifespan.

[0030] It should be noted that when air is heated, its molecules gain energy and begin to move violently, causing the distance between molecules to increase, thereby reducing the density of the gas. Because of its lower density, the hot air is lighter than the surrounding cooler air, so it rises until it reaches equilibrium with the temperature and density of the surrounding environment. The cooling fan 7 draws the hot air away from bottom to top, and the path of the hot air coincides with the drive path of the cooling fan 7, further improving its heat dissipation efficiency.

[0031] Please refer to Figures 1-3 In some embodiments of this example, a support platform 10 is provided on the housing 1, which is used to form a heat dissipation space with the SDN-based smart gateway on the desktop.

[0032] In this embodiment, the support platform 10 is located at the four corners of the housing 1, which is used to lift the gateway body as a whole, so as to facilitate the entry of air from outside the housing 1, thereby accelerating the airflow. The flowing air carries away the heat generated inside the housing 1, thus achieving heat dissipation.

[0033] Please refer to Figures 1-3 In some embodiments of this example, a rubber suction cup base 11 is provided at the end of the support platform 10 away from the housing 1.

[0034] In this embodiment, the aforementioned rubber suction cup base 11 can firmly adhere to a desktop, wall, or other smooth surface, providing stable support for the gateway body. This suction force not only helps prevent the gateway body from sliding or tipping over during use, but also ensures that the gateway body maintains a stable position in complex or tilted environments. Furthermore, the rubber material has a certain degree of elasticity and cushioning properties, capable of absorbing external impacts and vibrations. When the gateway body is subjected to accidental collisions or vibrations, the rubber suction cup can reduce the damage to the internal electronic components of the gateway body, improving its durability and stability.

[0035] Please refer to Figure 3 In some embodiments of this example, the input port of the cooling fan 7 is provided with a temperature sensing element 12, which is electrically connected to the SDN controller 2.

[0036] In this embodiment, the temperature sensing element 12 is used to accurately and in real-time measure the temperature of the gas discharged from the gateway body, which is a key prerequisite for realizing automatic control of the cooling fan 7. Precise temperature measurement ensures that the cooling fan 7 starts and stops at the appropriate time, effectively avoiding overheating or overcooling. Based on the temperature data provided by the temperature sensing element 12, the control system can automatically adjust the operating state of the cooling fan 7. When the gas temperature exceeds a preset safety threshold, the cooling fan 7 will automatically start to accelerate heat dissipation; when the temperature drops to a safe range, the cooling fan 7 will slow down or stop working to save energy and extend equipment life.

[0037] Please refer to 2. In some embodiments of this example, the housing 1 is provided with an indicator light 13 for displaying the working status of the cooling fan 7. The indicator light 13 is electrically connected to the SDN controller 2.

[0038] In this embodiment, the indicator light 13 can intuitively display the working status of the cooling fan 7, such as start, running, and stop. Users can quickly understand the working status of the cooling fan 7 by observing the on / off state or color change of the indicator light 13. The real-time display function of the indicator light 13 allows users to monitor the heat dissipation status of the gateway body at any time. Once an abnormality is found in the indicator light 13, users can take immediate measures, such as checking whether the cooling fan 7 is blocked or needs cleaning, thereby avoiding malfunctions or damage caused by overheating of the equipment.

[0039] Please refer to Figure 3 In some embodiments of this example, the air inlet 9 is covered with a dustproof net 14, which is located inside the housing 1.

[0040] In this embodiment, the main function of the dust filter 14 is to prevent dust, debris, and other contaminants from entering the air inlet 9 of the gateway body, thereby protecting the cooling fan and electronic components inside the gateway body from dust damage. Dust accumulation not only affects heat dissipation but can also lead to fan malfunction or short circuits in electronic components. The use of the dust filter 14 can significantly reduce dust accumulation inside the gateway body, thereby reducing the failure rate caused by dust. This helps extend the service life of the gateway body and reduce maintenance and replacement costs.

[0041] Please refer to Figures 1-3 In some embodiments of this example, heat dissipation fins 15 are provided on both sides of the housing 1.

[0042] In this embodiment, the main function of the heat dissipation fins 15 is to increase the contact area between the gateway housing 1 and the air, thereby improving heat dissipation efficiency. When heat is generated inside the gateway, the heat is transferred to the heat dissipation fins 15 through the thermally conductive material, and then the heat dissipation fins 15 dissipate the heat into the air. This heat dissipation method helps to reduce the operating temperature of the gateway and improve the stability and performance of the device. The heat dissipation fins 15 increase the contact area with the air, allowing heat to dissipate into the air more quickly, thereby reducing the operating temperature of the gateway. This helps to reduce equipment failure and performance degradation caused by overheating.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
