Technical Field

[0001] The utility model relates to the field of communication technologies and equipment, and particularly relates to a secure access gateway. Background Art

[0002] A security gateway realizes network interconnection at the data transmission level, can be applied to the interconnection of wide area networks and local area networks, and performs data transmission between two or more networks with different high-level protocols through protocol conversion functions. The main structure of the gateway is similar to that of a router device, and the difference is that it has a protective effect at the interconnection layer, ranging from protocol layer to application layer filtering, aiming to prevent the spread of unsafe factors in the data to the internal network on one's own side.

[0003] A security gateway often needs to be in an operating state for a long time or even continuously. The internal circuit board and electronic components will continuously emit and accumulate relatively high heat. If the heat cannot be dissipated and cooled in time, it will affect the performance of the device and the service life of the components. The existing heat dissipation of the security gateway mainly relies on the air-cooled heat dissipation method of directly blowing by a heat dissipation fan integrally installed on the gateway body. Not only is the heat dissipation effect average, but it also easily causes the resonance of the casing, generates noise and makes the components and wiring of surface mount assembly or plug-in connection loose and disconnected. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the defects that the existing integrated heat dissipation fan has poor heat dissipation effect on the gateway body and is prone to noise and vibration, and provide a secure access gateway, which realizes the overall cold flow heat dissipation of each position of the gateway by adding a heat dissipation rack, and reduces the vibration of the gateway body through hoisting, shock absorption, external fan and other means, while reducing noise, protecting the stability of the internal components of the gateway and the firmness of the wiring connection.

[0005] This secure access gateway includes a gateway body and a heat dissipation rack. The gateway body is hoisted inside the heat dissipation rack, and gaps are left between the upper, lower, left, right and rear sides of the gateway body and the inner wall of the heat dissipation rack. Among them, the heat dissipation rack is a hollow shell that is open at the front side and arc-shaped at the rear side. Fan groups are installed on both sides of the front side of the heat dissipation rack. Slots are opened on the arc-shaped back plate at the rear side of the heat dissipation rack, and a semiconductor refrigerating sheet is embedded in the slots. The fan group includes a pair of speed-adjustable fans, and the speed-adjustable fans blow from both sides of the heat dissipation rack towards the arc-shaped back plate at the rear side of the heat dissipation rack.

[0006] Further, four suspension rod mechanisms are penetrated through the four corners of the top plate of the heat dissipation rack. The suspension rod mechanism includes a suspension rod with a threaded part in the center, an adjusting nut, and a bearing platform. The bearing platform is fixed at the bottom of the suspension rod, and the adjusting nut is screwed onto the threaded part of the suspension rod above the heat dissipation rack.

[0007] Further, a supporting pad made of polyurethane soft material is provided on the bearing platform.

[0008] Further, it further includes a controller, and the controller includes a main control single-chip microcomputer, a relay module, and a power conversion module. The main control single-chip microcomputer is connected to the fan group and the semiconductor refrigerating sheet through the relay module, and the power conversion module supplies power to the fan group and the semiconductor refrigerating sheet respectively.

[0009] A secure access gateway of the present utility model overcomes the defects that the existing integrated cooling fan has poor heat dissipation effect on the gateway body and is prone to cause noise and vibration. By adding a heat dissipation rack, it realizes the overall cold flow heat dissipation of each position of the gateway. By means of hoisting, shock absorption, and external placement of the fan, etc., the vibration of the gateway body is reduced, while the noise is reduced, and the stability of the internal components of the gateway and the firmness of the wiring connection are protected.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0023] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "left", "right", "front", "back", "top", "bottom", "inner", "outer", etc. are all based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0024] The following uses specific embodiments to further describe the technical solution of the present utility model, but the protection scope of the present utility model is not limited to the following embodiments.

[0025] Embodiment 1: As Figures 1 to 5 shown, this secure access gateway includes a gateway main body 1 and a heat dissipation rack 2. The gateway main body 1 is hoisted inside the heat dissipation rack 2, and there are gaps between the upper, lower, left, right, and rear sides of the gateway main body 1 and the inner wall of the heat dissipation rack 2. Among them, the heat dissipation rack 2 is a hollow shell that is open at the front side and has an arc-shaped rear side. On both sides of the front side of the heat dissipation rack 2, a fan group 21 is installed. On the arc-shaped back plate 201 of the rear side of the heat dissipation rack 2, slots are opened, and a semiconductor refrigeration sheet 22 is embedded in the slots. The fan group 21 includes a pair of speed-adjustable fans 211, and the speed-adjustable fans 211 blow from both sides of the heat dissipation rack 2 towards the arc-shaped back plate 201 of the rear side of the heat dissipation rack 2.

[0026] Embodiment 2: Four suspension rod mechanisms 3 are installed through the four corners of the top plate of the heat dissipation rack 2 of this secure access gateway. The suspension rod mechanism 3 includes a suspension rod 31 with a threaded part 311 in the center, an adjusting nut 32, and a bearing platform 33. The bearing platform 33 is fixed at the bottom of the suspension rod 31, and the adjusting nut 32 is screwed onto the threaded part on the suspension rod 31 above the heat dissipation rack 2. The suspension rod mechanism is used to hoist the gateway main body. Among them, the four bearing platforms are used to support the lower part of the gateway host, and the adjusting nut is used to adjust the height of each bearing platform, so as to realize the horizontal hoisting of the gateway main body and the adjustment of the gap between the upper and lower surfaces of the gateway main body and the upper and lower inner walls of the heat dissipation rack. The rest of the structures and components are as described in Embodiment 1 and will not be repeated.

[0027] Embodiment 3: A polyurethane soft material cushion 331 is provided on the bearing platform 33 of the present security access gateway. The polyurethane soft material has a certain memory deformation function, which can compensate for small-angle deviations on the surface of the bearing platform at the bottom of the gateway main body during the adjustment of the suspension rod. At the same time, it has a shock-absorbing effect and can isolate the low-frequency vibration generated during the operation of the fan and the refrigeration chip from being transmitted to the gateway main body. The remaining structures and components are as described in Embodiment 1 and will not be repeated.

[0028] Embodiment 4: As Figure 6 shown, the present security access gateway further includes a controller 4. The controller includes a main control single-chip microcomputer 41, a relay module 42, and a power conversion module 43. The main control single-chip microcomputer 41 is connected to the fan group 21 and the semiconductor refrigeration chip 22 through the relay module 42, and the power conversion module 43 supplies power to the fan group 21 and the semiconductor refrigeration chip 22 respectively. The signal input end of the main control single-chip microcomputer is connected to the temperature sensor inside the gateway main body. The power conversion module converts, steps down, and stabilizes the external power supply and then supplies power to the fan group and the semiconductor refrigeration chip respectively. The controller drives the fan group motor and the semiconductor refrigeration chip to operate electrically by controlling the corresponding relays on the relay module. The remaining structures and components are as described in Embodiment 1 and will not be repeated.

[0029] During operation: The cold surface of the semiconductor refrigeration chip is located inside the heat dissipation machine frame housing, and the hot surface is located outside the heat dissipation machine frame housing. When the controller receives a signal of too high temperature from the temperature sensor inside the gateway main body, it drives the semiconductor refrigeration chip to operate, cooling the air behind the gateway main body. If the temperature continues to rise, the controller then drives one or two speed-regulating fans to operate and send air, pressing out the cooled air behind the gateway main body, so that the cold flow covers all sides of the entire main body of the machine. After the temperature drops, the speed-regulating fans are turned off in sequence first, and then the operation of the semiconductor refrigeration chip is stopped. The operation and stop sequences of the fan and the refrigeration chip can be programmed and modified in the controller single-chip microcomputer according to the characteristics of the gateway.

[0030] The present security access gateway overcomes the defects of the existing integrated cooling fan having poor heat dissipation effect on the gateway body and being prone to noise and vibration. By adding a heat dissipation machine frame, it realizes the overall cold flow heat dissipation of each position of the gateway, reduces the vibration of the gateway body through methods such as hoisting, shock absorption, and external placement of the fan, reduces noise, and protects the stability of the internal components of the gateway and the firmness of the wiring connection.
