[0028] Example: Reference Figure 1-6 An edge computing gateway shown includes a base 1 and an upper shell 2, the base 1 and the upper shell 2 are detachably connected by fasteners to form an integral shell, the front and rear ends of the base 1 are provided with data interfaces 11 of different models, the upper end of the upper shell 2 is integrally formed with a top heat dissipation fin 21, and the two sides of the upper shell 2 are integrally formed with side heat dissipation fins 22;

[0029] An air outlet 23 and an air inlet 24 are provided on both sides of the upper shell 2, and the air outlet 23 and the air inlet 24 are located at the upper and lower ends respectively;

[0030] A mainboard 4 electrically connected to the data interface 11 is fixedly mounted on the base 1 and is used for data collection, data processing, feedback, recording and storage, etc.;

[0031] A guiding heat dissipation plate 3 is fixed to the top wall of the upper shell 2, and the guiding heat dissipation plate 3 is a plate-shaped structure with a middle portion protruding downward;

[0032] A first arc-shaped guiding arc surface 31 is formed at the lower end of the guiding heat dissipation plate 3. The width of the middle section of the first guiding arc surface 31 is the largest and protrudes downward. The width of the two ends of the section of the first guiding arc surface 31 gradually decreases and extends toward the two ends of the guiding heat dissipation plate 3. The corners at both ends of the first guiding arc surface 31 are located in the same horizontal plane as the upper end of the air outlet 23.

[0033] Based on the above structure, the mainboard 4 in the shell formed by the base 1 and the upper shell 2 generates heat during operation, so that the air inside the base 1 and the upper shell 2 heats up, the hot air rises, and is guided by the first guide arc surface 31 at the lower end of the heat sink 3 to move to the air outlets 23 on both sides. After guidance, the air flow is smoother and it is not easy to form a top retention layer; at the same time, the air outlet 23 and the air inlet 24 opened on both sides of the upper shell 2 allow the external air to enter from the lower end and be discharged from the upper end, and be divided into two parts of air flow along the middle part of the first guide arc surface 31, thereby forming two left and right circulating airflows in the internal space of the base 1 and the upper shell 2, thereby enhancing the airflow effect, and at the same time guiding the kinetic potential energy generated by the gas itself, so that a better airflow circulation can be formed inside the edge computing gateway without a heat dissipation fan, and the movement is smoother, which can break the airflow retention layer inside the traditional edge computing gateway, form a practical and effective heat dissipation airflow circulation, enhance the heat dissipation effect, and avoid the operating load that may be caused by the heat dissipation fan.

[0034] Furthermore, a second guiding arc surface 35 is formed at both ends of the guiding heat dissipation plate 3. The second guiding arc surface 35 is an upwardly concave arc surface. The width of the cross section of the second guiding arc surface 35 is the largest at both ends and the smallest in the middle and is consistent with the minimum width of the first guiding arc surface 31.

[0035] By setting the second guide arc surface 35, the left and right airflows separated along the first guide arc surface 31 are further gathered to a certain extent, so that the gas discharge is more concentrated and the gas diffusion along the front and rear sides is avoided, thereby further ensuring the smoothness of gas movement and improving the heat dissipation effect.

[0036] Furthermore, a heat exchange cavity 32 is provided in the guiding heat dissipation plate 3; an air inlet 33 penetrating the lower end of the guiding heat dissipation plate 3 is provided in the middle of the guiding heat dissipation plate 3, and the air inlet 33 connects the inner cavity of the shell composed of the base 1 and the upper shell 2 with the heat exchange cavity 32;

[0037] Air outlet holes 34 are formed at both ends of the guiding heat dissipation plate 3 , and the air outlet holes 34 communicate with the heat exchange cavity 32 and the air outlet 23 .

[0038] By setting the heat exchange cavity 32, the air inlet 33 and the air outlet 34, part of the air can enter the heat exchange cavity 32 through the air inlet 33 and be discharged from the air outlet 34, thereby expanding the heat exchange area between the gas and the guide heat sink 3, enhancing the heat exchange rate per unit time, and thus enhancing the heat dissipation efficiency of the edge computing gateway.

[0039] Furthermore, the inner walls on both sides of the air inlet 33 form an air guiding slope 331 which is inclined from both sides to the middle, and the opening area of ​​the lower end of the air guiding slope 331 is larger than the opening area of ​​the upper end of the air guiding slope 331 .

[0040] Furthermore, the air outlet 23 is an oblique opening inclined upward, and first baffles 25 are fixed on both sides of the upper shell 2. The first baffles 25 are arranged to be inclined downward, and the connection between the first baffle 25 and the upper shell 2 is located above the air outlet 23. The first baffle 25 is also provided with a through hole that vertically penetrates the first baffle 25 and is close to the opening of the air outlet 23.

[0041] The air outlet 23 is arranged as an oblique opening inclined upward, so that the hot air can be discharged easily, thus facilitating the flow of airflow.

[0042] Furthermore, the air inlet 24 is also an inclined opening inclined upward, and second baffles 26 are fixed on both sides of the upper shell 2. The second baffles 26 are located above the outer opening of the air inlet 24, and a downward inclined slope is formed at the bottom of the second baffle 26;

[0043] By setting the air inlet 24 as an upwardly inclined oblique opening, the external cold air can form downward-moving gas when entering, so that the cold air can move inward along the inner bottom of the base 1 and be evenly distributed in the bottom area of ​​the base 1, so that the cold air can evenly absorb more heat after entering, thereby improving the heat dissipation effect of the airflow.

[0044] Working principle of the utility model: during daily use, external cold air enters the base 1 and the upper shell 2 through the air inlet 24 and forms gas moving downward, so that the cold air can move inward along the inner bottom of the base 1 and be evenly distributed in the bottom area of ​​the base 1; the air that absorbs heat rises and is guided by the first guiding arc surface 31 at the lower end of the guide heat sink 3 to move to the air outlets 23 on both sides. After guidance, the air flow is smoother and it is not easy to form a top retention layer. The airflow is divided into left and right parts along the middle part of the first guiding arc surface 31, thereby forming two left and right circulating airflows in the internal space of the base 1 and the upper shell 2, thereby enhancing the airflow effect and guiding the kinetic potential energy generated by the gas itself, so that a better airflow circulation can be formed inside the edge computing gateway without a cooling fan, and the movement is smoother, which can The airflow retention layer inside the traditional edge computing gateway is broken to form an effective heat dissipation airflow circulation, enhance the heat dissipation effect, and avoid the operating load that may be caused by the installation of a heat dissipation fan; the second guide arc surface 35 further plays a certain gathering effect on the left and right parts of the airflow separated along the first guide arc surface 31, so that the gas discharge is more concentrated, avoiding the gas from diffusing along the front and back sides, thereby further ensuring the smoothness of gas movement and ensuring the improvement of the heat dissipation effect; part of the air enters the heat exchange chamber 32 from the air inlet 33 and is discharged from the air outlet 34, thereby expanding the heat exchange area between the gas and the guide heat dissipation plate 3, enhancing the heat exchange rate per unit time, and thus enhancing the heat dissipation efficiency of the edge computing gateway; the air outlet 23 is set to be an inclined port inclined upward, which can facilitate the discharge of hot air, thereby facilitating the flow of airflow.
