Description

Technical Field

[0001] This utility model relates to the field of discharge cabinet technology, and in particular to a heat dissipation and waterproof structure for discharge cabinets. Background Technology

[0002] "Discharge cabinet" usually refers to a special device used to safely release electrical energy stored in equipment or systems. It is commonly found in power, industrial or laboratory settings. In addition, discharge machines operate in open-air environments, so they must withstand harsh weather conditions such as strong winds, heavy rain, and scorching sun.

[0003] In existing technologies, some discharge cabinets have a set of fan structures installed on the back or sides of the cabinet to achieve heat dissipation. However, the design of the cooling fan also causes a large amount of dust to enter the cabinet from the fan frame. Dust covering electronic components may cause electrostatic discharge, which can damage the components.

[0004] Other manufacturers use ventilation channels in the cabinet for heat dissipation. However, the cabinet itself is only a single layer of sheet metal. Without a suitable structure, rainwater can easily leak into the cabinet, damaging the electronic components inside. Therefore, providing a waterproof structure for the cabinet to prevent rainwater from entering is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a heat dissipation and waterproof structure for a discharge cabinet, thereby solving the aforementioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a heat dissipation and waterproof structure for a discharge cabinet, comprising a cabinet body and a vent on the cabinet body communicating with the inner cavity of the cabinet body, wherein a protective structure corresponding to the vent is provided inside the cabinet body; the protective structure includes a connector, a guide plate and a baffle, the guide plate being located between the baffle and the vent, the connector being located below the vent, one side being connected to the lower part of the guide plate, and forming a liquid collection groove at the top of the connector; at least one ventilation section communicating with the inner cavity of the cabinet body is provided between the baffle and the guide plate, and the ventilation section is located above the liquid collection groove.

[0007] Furthermore, the deflector includes a mounting frame and multiple inclined plates. The mounting frame is a hollow plate, and the multiple inclined plates are spaced apart on the side of the mounting frame near the vent.

[0008] Furthermore, the mounting frame includes a main frame and an extension plate. One side of the extension plate is connected to a connector. The liquid collection tank is located between the extension plate and the inner wall of the cabinet. The main frame is located above the liquid collection tank.

[0009] Furthermore, the ventilation section is located between the lower end of the baffle and the connection between the main frame and the extension plate.

[0010] Furthermore, the lower end of the main frame is horizontal and has an opening that connects to the liquid collection tank.

[0011] Furthermore, the inclined plate is tilted toward the baffle, and the inclined end of the inclined plate faces upward.

[0012] Furthermore, the plurality of inclined plates include a plurality of first inclined plates and a second inclined plate, the lower end of the second inclined plate being connected to the mounting frame.

[0013] Furthermore, each of the first inclined plates has an extension plate at its lower end, and the straight-line distance between the side edge of the lower end of the previous extension plate and the side edge of the upper end of the next first inclined plate is less than 5 mm.

[0014] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, when the discharge cabinet is placed in the outside and it rains, rainwater enters the cabinet through the vent. Due to the obstruction of the guide plate, it drips into the collection tank, so that the rainwater entering the cabinet will not come into contact with the baffle and prevents rainwater from entering the cabinet cavity through the vent. In addition, since the vent is located above the collection tank, it further prevents rainwater from entering the cabinet cavity through the vent. Thus, while the discharge cabinet can dissipate heat normally, it can also prevent rainwater from entering the cabinet cavity and coming into contact with the electrical components inside.

[0015] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0020] Cabinet 10;

[0021] 20 ventilation openings;

[0022] Protective structure 30, connector 31, guide plate 32, mounting frame 321, main frame 3211, extension plate 3212, opening 3213, inclined plate 322, first inclined plate 3221, second inclined plate 3222, extension plate 323, baffle 33, liquid collection tank 34, venting section 35. Detailed Implementation

[0023] Please refer to Figure 1-3 As shown, it illustrates the specific structure of a preferred first embodiment of the present invention, which is a heat dissipation and waterproof structure for a discharge cabinet. It includes a cabinet body 10 and a vent 20 disposed on the cabinet body 10 and communicating with the inner cavity of the cabinet body 10. The cabinet body 10 is provided with a protective structure 30 corresponding to the vent 20. The protective structure 30 includes a connector 31, a guide plate 32 and a baffle 33. The guide plate 32 is located between the baffle 33 and the vent 20. The connector 31 is disposed below the vent 20, with one side connected to the lower part of the guide plate 32, and a liquid collection groove 34 is formed at the top of the connector 31. At least one ventilation part 35 communicating with the inner cavity of the cabinet body 10 is provided between the baffle 33 and the guide plate 32, and the ventilation part 35 is located above the liquid collection groove 34. When the discharge cabinet is placed outdoors and it rains, rainwater enters the cabinet 10 through the vent 20. Due to the obstruction of the guide plate 32, the rainwater drips into the collection tank 34, preventing the rainwater entering the cabinet 10 from contacting the baffle 33 and avoiding rainwater from entering the inner cavity of the cabinet 10 through the vent 35. In addition, since the vent 35 is located above the collection tank 34, it further prevents rainwater from entering the inner cavity of the cabinet 10 through the vent 35. Thus, while the discharge cabinet can dissipate heat normally, it can also prevent rainwater from entering the inner cavity of the cabinet 10 and contacting the electrical components inside.

[0024] For example, the deflector 32 includes a mounting frame 321 and a plurality of inclined plates 322. The mounting frame 321 is a hollow plate, and the plurality of inclined plates 322 are spaced apart on the side of the mounting frame 321 near the vent 20. The mounting frame 321 increases the distance between the vent 20 and the baffle 33, so that after rainwater enters the cabinet 10 through the vent 20, the rainwater that hits the inclined plates 322 will have enough distance to travel even if it passes through the inclined plates 322, thus preventing it from splashing onto the baffle 33.

[0025] Specifically, the mounting frame 321 includes a main frame 3211 and an extension plate 3212. One side of the extension plate 3212 is connected to the connector 31. The liquid collection tank 34 is located between the extension plate 3212 and the inner wall of the cabinet 10, and the main frame 3211 is located above the liquid collection tank 34. The main frame 3211 and the extension plate 3212 can be integrally formed, while the connection between the extension plate 3212 and the connector 31 is welding or other sealing connections, separating the liquid collection tank 34 from the inner cavity of the cabinet 10, so that rainwater in the liquid collection tank 34 will not enter the inner cavity of the cabinet 10 and damage the electrical components inside.

[0026] For example, the ventilation section 35 is located between the lower end of the baffle 33 and the connection between the main frame 3211 and the extension plate 3212. The ventilation section 35 is located at the lower end of the baffle 33 because the electrical components inside the cabinet 10 generate heat during operation. When the air is heated, the kinetic energy of the gas molecules increases, their speed increases, and the average distance between molecules increases, causing the air volume to expand and the density to decrease. After the density decreases, objects with lower density will float due to the buoyancy of the surrounding fluid, making it easier for cool air to enter the cabinet 10 and cool the electrical components inside the cabinet 10 from bottom to top.

[0027] It should be noted that, in order to enhance the cooling effect inside the cabinet 10, an air venting component can also be installed above the cabinet 10, but that is unrelated to the structure to be protected in this application, and will only be briefly mentioned here.

[0028] Specifically, the lower end of the main frame 3211 is horizontal and has an opening 3213 that communicates with the liquid collection tank 34. In order to prevent rainwater from accumulating inside the main frame 3211 through the inclined plate 322, an opening 3213 communicating with the liquid collection tank 34 is required at the lower end of the main frame 3211 to prevent rainwater from accumulating inside the main frame 3211.

[0029] The inclined plate 322 is tilted toward the baffle 33, and the inclined end of the inclined plate 322 faces upward. Because the inclined plate 322 is tilted upward, rainwater dripping onto the inclined plate 322 is not easy to pass through the inclined plate 322, but will naturally slide down and drip into the collection tank 34 under the action of gravity.

[0030] Specifically, the plurality of inclined plates 322 includes a plurality of first inclined plates 3221 and a second inclined plate 3222, the lower end of the second inclined plate 3222 being connected to the mounting frame 321.

[0031] Each of the multiple first inclined plates 3221 has an extension plate 323 at its lower end, and the straight-line distance between the lower edge of the previous extension plate 323 and the upper edge of the next first inclined plate 3221 is less than 5 mm. Because the distance between adjacent extension plates 323 and first inclined plates 3221 is less than 5 mm, rainwater dripping onto the first inclined plate 3221 is more difficult to pass through the first inclined plate 3221.

[0032] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
