[0023] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0024] like Figures 1 to 7 In the embodiment of the heat dissipation protection device for electromechanical equipment of the utility model shown in the figure, the heat dissipation protection device for electromechanical equipment comprises a cabinet 1, a filter assembly 2, a wind dispersion plate 3, an exhaust fan 4 and an equipment bracket 5. A filter assembly 2 is provided at the bottom of one side wall of the cabinet 1, and the filter assembly 2 blocks dust from entering the cabinet 1; the filter assembly 2 is connected to the air inlet cavity 101 at the bottom of the cabinet 1, and a wind dispersion plate 3 is fixedly provided on the upper side of the air inlet cavity 101. The length direction of the plurality of wind dispersion holes 301 on the wind dispersion plate 3 is parallel to the filter assembly 2, and the closer the distance from the filter assembly 2 is, the closer the distance from the filter assembly 2 is. The larger the aperture of the air dispersion hole 301 is, the greater the ventilation flow rate is, and the smaller the aperture is, the smaller the ventilation flow rate is. When the air enters the air inlet cavity 101 from the filter component 2, only a part of the air passes through the air dispersion hole 301 close to the filter component 2, and the remaining air continues to move away from the filter component 2 and passes through the air dispersion hole 301 far away from the filter component 2, so that the air flow rate passing through the air dispersion plate 3 is inconsistent; the air dispersion hole 301 is conical with its apex facing the air inlet cavity 101, and the air dispersion hole 301 is fixed A wind dispersion cone 31 with its apex facing the air inlet cavity 101 is fixedly provided; the conical wind dispersion hole 301 cooperates with the conical wind dispersion cone 31 to disperse the air entering from the filter component 2 and blow it toward the equipment bracket 5 fixed on the upper side of the wind dispersion plate 3, so as to evenly cool the electromechanical equipment on the equipment bracket 5; the exhaust fan 4 is arranged on the upper side of the side wall of the cabinet 1 on which the filter component 2 is arranged, that is, the farther the wind dispersion hole 301 is from the exhaust fan 4, the larger the aperture is. In view of the fact that the air near the exhaust fan 4 is in a negative pressure state, the air farther away from the exhaust fan 4 is closer to the atmospheric pressure. Therefore, part of the air entering from the filter component 2 will preferentially pass through the air dispersion holes 301 close to the exhaust fan 4 due to the exhaust effect of the exhaust fan 4. Because the aperture of the air dispersion holes 301 closer to the exhaust fan 4 is smaller, part of the air will not be able to pass through the air dispersion holes 301 close to the exhaust fan 4 and will move away from the filter component 2, and further pass through the air dispersion holes 301 away from the filter component 2. In this way, the filter component 2, the air dispersion plate 3 and the exhaust fan 4 cooperate with each other to make the air flowing to the equipment bracket 5 tend to be uniform, thereby achieving a good heat dissipation effect.

[0025] In one embodiment of the present application, preferably, Figure 2 , Figure 5 and Figure 6 As shown, the top surface of the air inlet cavity 101 is fixed with the air dispersion plate 3 and the equipment bracket 5 by bolts, and sealing gaskets are provided between the cabinet 1 and the air dispersion plate 3, and between the air dispersion plate 3 and the equipment bracket 5. The sealing connection through the sealing gasket can improve the heat dissipation efficiency of the equipment and achieve a good heat dissipation effect.

[0026] In one embodiment of the present application, preferably, Figure 6 , Figure 7 As shown, the air dispersion cones 31 on the air dispersion plate 3 have the same shape and size, and the inclination angles of the conical surfaces of the heat dissipation holes are consistent. In this way, the aperture size of the air dispersion hole 301 is the variable that affects the air flow rate, and the air dispersion cones 31 will not affect the air flow rate in the air dispersion hole 301.

[0027] In one embodiment of the present application, preferably, Figure 5 , Figure 6 As shown, a ventilation gap is provided between the air dispersing plate 3 and the equipment bracket 5, that is, the legs on the equipment bracket 5 have a certain height, so that the air dispersing effect of the air dispersing plate 3 can be fully utilized, that is, the air dispersing effect further enables the electromechanical equipment to achieve a good heat dissipation effect.

[0028] In one embodiment of the present application, preferably, Figure 2 , Figure 5 and Figure 6 As shown, the equipment bracket 5 is provided with a vent 501, and the vent 501 is oriented toward the extension direction of the gap between the air dispersion hole 301 and the air dispersion cone 31; the equipment bracket 5 not only plays a supporting role, but also plays a role in providing a ventilation channel for the electromechanical equipment on the equipment bracket 5. The vent 501 allows the dispersed air passing through the air dispersion plate 3 to reach the surface of the electromechanical equipment 5, so as to achieve a good heat dissipation effect.

[0029] In one embodiment of the present application, preferably, Figure 2 , Figure 5 and Figure 6 As shown, the equipment bracket 5 is fixedly provided with a grid 51 in the vent 501, and the grid 51 plays a supporting and ventilating role; in order to ensure the bearing effect of the equipment bracket 5, a hard grid 51 is used to fill the vent 501, which can effectively support the relay equipment without hindering ventilation.

[0030] In one embodiment of the present application, preferably, Figures 2 to 5 As shown, the cabinet 1 has an air inlet cavity 101 below the air dispersing plate 3, and an equipment cavity 102 above the air dispersing plate 3. An exhaust fan 4 is arranged on the side wall of the equipment cavity 102, and an exhaust hole 103 for exhausting air is also arranged on the equipment cavity 102; a cabinet door 11 is arranged on the equipment cavity 102, and the cabinet door 11 is sealed and connected to the cabinet 1. It is worth noting that the exhaust fan 4 can be arranged not only on the side wall of the cabinet 1, but also on the cabinet door 11. Specifically, the relative positions of the exhaust fan 4, the filter assembly 2 and the cabinet door 11 are set based on the actual environment where the electromechanical equipment is located.

[0031] In one embodiment of the present application, preferably, Figure 3 , Figure 4 As shown, the filter assembly 2 includes a mesh cover 21 and a filter element 22. The filter element 22 is clamped and fixed in the filter element slot 103 of the cabinet 1 by the mesh cover 21, so that the filter element 22 can be easily replaced.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
