Description

Technical Field

[0002] A gateway device, also known as an internetwork connector or protocol converter, is a computer system or device that provides data conversion services between multiple networks. Since the space of the gateway device is limited, when a large number of parts are installed inside it, the space between the parts will be relatively narrow. During the working process, due to high-frequency operation, the gateway device will generate a large amount of heat. If the gateway device is not cooled in time, the excessive heat will damage the gateway device. Therefore, most existing gateway devices are equipped with a heat dissipation function.

[0003] In the prior art, a gateway device that is easy to dissipate heat includes a housing. A plurality of equally spaced air outlet holes are provided on the left side of the housing. The bottom of the inner cavity of the housing is fixedly connected with a fan housing. A small motor is arranged in the inner cavity of the fan housing. The output shaft of the small motor is fixedly connected with a fan blade. The top of the housing is rotatably connected with a flip cover through a hinge. The top of the inner cavity of the flip cover is fixedly connected with a gateway device. However, the method of only using an exhaust fan to discharge the residual heat in the housing for heat dissipation cannot achieve a good natural heat dissipation effect, and the heat dissipation method is single.

[0035] Figure 8 Schematic diagram of the dust-proof cloth in the gateway device in the embodiment of the present invention; As Figures 1-8 shown, this embodiment provides a gateway device, including: a device body 1; a fan, arranged on the heat dissipation surface of the device body 1, the air inlet of the fan is connected to the outside atmosphere, and the air outlet of the fan is connected to the inner cavity of the device body 1; a humidifying mechanism 7, arranged on the device body 1, the humidifying mechanism 7 is configured at the air inlet of the fan, and is suitable for cooling and humidifying the air entering the device body 1 through the air inlet of the fan.

[0036] For the gateway device provided in this embodiment, in addition to using a fan to dissipate heat from the device body 1, the humidifying mechanism 7 can also be used to cool and humidify the air conveyed by the fan, so that the heat dissipation method is more diversified and the heat dissipation effect is better; moreover, even when the outside air temperature is relatively high, the heat dissipation effect can be guaranteed, improving the applicability of the device body 1.

[0039] Among them, the gateway device further includes a guiding mechanism 6, and the guiding mechanism 6 includes a conveying pipe 62. One end of the conveying pipe 62 extends into the gap between the first dust-proof net 3 and the heat sink 4, and the other end is communicated with the air outlet of the fan.

[0040] Among them, the gateway device further includes a second dust-proof net 61, which is arranged at the air inlet of the fan. The second dust-proof net 61 and the humidifying mechanism 7 are located on different sides of the heat dissipation surface; the housing 63 of the fan is buckled with the second dust-proof net 61 to form an air chamber, and the fan blades 64 of the fan are arranged in the air chamber; one end of the conveying pipe 62 far from the heat sink 4 extends into the air chamber.

[0041] Among them, the gateway device further includes a dust-proof mechanism 8, and the dust-proof mechanism 8 includes a dust-proof frame 81; the dust-proof frame 81 covers the outside of the air-permeable frame 72.

[0042] Among them, the dust-proof mechanism 8 further includes a scraping rack 82, an electromagnet 83 and a controller 84; the scraping rack 82 is slidably arranged between the air-permeable frame 72 and the dust-proof frame 81; the electromagnet 83 and the controller 84 are both arranged on the second protective net, and both the electromagnet 83 and the fan are electrically connected to the controller 84. The controller 84 is adapted to control the electromagnet 83 to be energized when the fan starts, so as to drive the scraping rack 82 to move along the surface of the air-permeable frame 72.

[0043] Among them, the gateway device further includes a breathable cloth 10, which is arranged between the inner wall of the dust-proof frame 81 and the outer wall of the air-permeable frame 72.

[0044] Among them, the gateway device further includes a support block 2, which is arranged on the heat dissipation surface of the device body 1, and the height of the support block 2 exceeds the height of the fan and the humidifying mechanism 7 in the height direction of the device body 1.

[0045] Among them, the gateway device further includes an adjusting mechanism 9, and the adjusting mechanism 9 includes a hinge block 91, a rotating rod 92 and a support member 93; the rotating rod 92 is rotatably arranged on the heat dissipation surface of the device body 1 through the hinge block 91. The rotating rod 92 has a retracted state of rotating to be parallel to the heat dissipation surface, and an unfolded state of rotating to be inclined relative to the heat dissipation surface; the support member 93 is arranged on the hinge block 91 and is adapted to abut against the rotating rod 92 when the rotating rod 92 is in the unfolded state to limit the continuous rotation of the rotating rod 92.

[0046] Among them, at least part of the surface of the device body 1 has a concave-convex structure to increase the contact area between the device body 1 and the air.

[0047] Specifically, such as Figures 1-3As shown in the figure, the gateway device provided in this embodiment includes a device body 1, a support block 2, a first dust-proof net 3, heat sinks 4, heat conduction sheets 5, a guiding mechanism 6, and a humidifying mechanism 7. The bottom of the device body 1 is connected to a support block 2 made of anti-slip material. The support block 2 is a rubber suction cup for sticking the device body 1 to the support platform. For example, the top surface (the surface opposite to the heat dissipation surface) of the device body 1 has a wavy concave-convex structure, which is used to increase the contact area between the device body 1 and the air, facilitating the air flow to carry away excess heat. For example, a first dust-proof net 3 can be penetrated through the bottom of the device body 1, and heat sinks 4 are bolted to the first dust-proof net 3. A heat conduction sheet 5 for transferring heat is provided on the side of the heat sink 4 close to the inside of the device body 1. The device body 1 is provided with a guiding mechanism 6 for guiding the air flow direction and a humidifying mechanism 7 for increasing the air humidity.

[0048] As Figure 3 and Figure 5 As shown in the figure, four second dust-proof nets 61 are penetrated through the bottom of the device body 1 and are distributed along the diagonal line of the heat dissipation surface. A plurality of conveying pipes 62 are connected between each second dust-proof net 61 and the first dust-proof net 3. The housing 63 of a blower is buckled on the side of the second dust-proof net 61 close to the inside of the device body 1. The fan blade 64 of the blower is arranged in the air chamber formed by the housing and the second dust-proof net. By rotating the fan blade 64, the outside air can be sucked into the air chamber.

[0049] The operator can apply the corresponding technical solutions in this device to the technology of a gateway device with good heat dissipation performance according to specific situations. When the operator needs to use this gateway device, first, the operator places the device body on the desktop. The support block 2 supports the device body away from the desktop and sticks the device body to the desktop, thus facilitating the air circulation and increasing the stability of the device body. At the same time, the concave-convex structure of the device body 1 can increase the contact area between the device body 1 and the air, facilitating the air flow to carry away excess heat. When the temperature inside the device body 1 rises, the heat conduction sheet 5 will transfer the temperature inside the device body 1 to the heat sinks 4, and the heat sinks 4 quickly achieve the effect of natural heat dissipation. The first dust-proof net 3 will prevent dust and other foreign objects from entering the heat sinks 4. When the temperature inside the device body 1 is too high, the operator starts the blower, which will accelerate the air circulation. The air will flow into the first dust-proof net 3 through the second dust-proof net 61 and the conveying pipes 62 to dissipate heat from the heat sinks 4, thereby carrying away the excess heat on the heat sinks 4 and improving the heat dissipation effect. During this process, the second dust-proof net 61 will prevent dust and other foreign objects from entering the blower, thus achieving the dust-proof effect while achieving the heat dissipation effect and improving the practicability of this device. After the temperature inside the device body 1 drops, the operator can turn off the blower.

[0050] In another embodiment, as Figure 4 and Figure 5As shown in the figure, the humidifying mechanism 7 includes a water storage tank 71, a ventilation frame 72, and a water absorbent cotton 73. Two water storage tanks 71 for storing liquid for cooling air are bolted to the lower side of the equipment body 1 and are arranged symmetrically front and back. The lower part of the water storage tank 71 communicates with two ventilation frames 72 arranged symmetrically left and right. The ventilation frame 72 is located directly below the second dust-proof net 61. The ventilation frame 72 and the fan are on different sides of the second dust-proof net 61. A water absorbent cotton 73 for adsorbing the liquid stored in the water storage tank 71 is provided between the ventilation frame 72 and the water storage tank 71.

[0051] The operator injects the water liquid into the water storage tank 71. The water liquid in the water storage tank 71 will wet the water absorbent cotton 73. The ventilation frame 72 will support the water absorbent cotton 73 and achieve the ventilation effect. In this way, when the fan is running, the temperature of the air is reduced by the water liquid on the water absorbent cotton 73, and the heat dissipation effect during air circulation is improved. The air circulation is ensured through the ventilation frame 72, and the use of the fan is guaranteed.

[0052] In another embodiment, as Figure 2 , Figure 5 and Figure 6 shown, it further includes a dust-proof mechanism 8 for preventing dust from entering the equipment body 1. The dust-proof mechanism 8 includes a dust-proof frame 81, a scraping frame 82, an electromagnet 83, and a controller 84. Four dust-proof frames 81 are bolted to the lower side of the equipment body 1. The four dust-proof frames 81 surround the outside of the ventilation frame 72 one by one. A scraping frame 82 for cleaning the sundries attached thereto is slidably sleeved in the middle of the ventilation frame 72. Electromagnets 83 for adsorbing the scraping frame 82 are respectively embedded and bolted on the front and rear sides of the lower part of the second dust-proof net 61, and a controller 84 electrically connected to the fan and the electromagnet 83 is provided. For example, the material of the scraping frame 82 is iron.

[0053] As Figure 8 shown, it further includes a ventilation cloth 10. A ventilation cloth 10 for ventilation and dust-proof is connected to the equipment body 1 between the ventilation frame 72 and the dust-proof frame 81.

[0054] Since the dust-proof frame 81 surrounds the ventilation frame 72, the dust-proof frame 81 will further achieve the dust-proof effect. When the fan is started, the fan will control the electromagnet 83 to be energized through the controller 84. The electromagnet 83 will adsorb the scraping frame 82 to move upward. The upward movement of the scraping frame 82 will scrape off the sundries attached to the ventilation frame 72, so as to ensure the air circulation. Finally, when the fan is turned off, the fan will control the electromagnet 83 to be de-energized through the controller 84 to release the scraping frame 82. The scraping frame 82 will move downward under the action of gravity to reset and scrape the sundries attached to the ventilation frame 72 again. When the operator needs to process the sundries, the operator can disassemble the device. In addition, the ventilation cloth 10 can achieve the ventilation and dust-proof effect between the ventilation frame 72 and the dust-proof frame 81.

[0055] In another embodiment, as Figure 2 and Figure 7 shown, the gateway device further includes an adjusting mechanism 9 for increasing the support height. The adjusting mechanism 9 includes a hinge block 91, a rotating rod 92, and a support member 93. Four hinge blocks 91 can be bolted to the four corner positions on the lower side of the device body 1. The lower part of the hinge block 91 is integrally and rotatably connected to a rotating rod 92 for supporting the device body 1. When the rotating rod 92 is in the retracted state, the lowest point of the rotating rod 92 is higher than the lowest point of the support block 2. When the rotating rod 92 is in the deployed state, the lowest point of the rotating rod 92 is lower than the lowest point of the support block 2. The rotating rod 92 has a retracted state in which it is horizontally arranged and a deployed state in which it is inclined and is adapted to be converted between the retracted state and the deployed state under the action of an external force. A support member 93 for supporting the rotating rod 92 is provided outside the hinge block 91. The rotating rod 92 is made of iron, and the support member 93 has magnetism. The rotating rod 92 is fixed by adsorbing the rotating rod 92 through the support member 93.

[0056] Initially, the rotating rod 92 is in the retracted state. The operator rotates the rotating rod 92, and when the rotating rod 92 rotates, it will bypass the lower part of the support block 2, thereby deploying the rotating rod 92. When the device body is placed on a tabletop, the device body can be supported by the rotating rod 92, and the supported height is higher than the height supported by the support block 2, thereby achieving diversified support. When the gateway device needs to be placed where the cables are intertwined, pressing the rotating rod 92 on the cables can stably place the gateway device, and at the same time keep the gateway device away from the cables, further ensuring the heat dissipation effect.

[0057] In summary, for the gateway device in the present application, a good diversified natural heat dissipation effect is achieved through the support block, the concave-convex structure of the device body, the heat sink, and the heat conducting sheet. Multiple fans work simultaneously for heat dissipation, and the temperature of the air is reduced by the water liquid on the water-absorbing cotton, improving the heat dissipation effect during air circulation, and the heat dissipation effect is good.

[0058] For the gateway device in the present application, when the fan is started, the electromagnet can be controlled to be energized through the controller, and the electromagnet will adsorb the scraping frame to move upward. The upward movement of the scraping frame will scrape off the sundries attached to the air-permeable frame, thereby ensuring the air circulation.

[0059] For the gateway device in the present application, the rotating rod is used to support the device body instead of the support block, and the supported height is higher than the height supported by the support block, thereby achieving diversified support and improving the heat dissipation effect. When the gateway device needs to be placed where the cables are intertwined, pressing the rotating rod on the cables can stably place it, and at the same time keep the gateway device away from the cables, ensuring the heat dissipation effect.

[0060] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to exhaustively list all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
