[0032] Reference Figures 1 to 7According to a first aspect of the present invention, a high-efficiency heat dissipation cabinet includes a cabinet body 100, a heat dissipation fan 200, and a first partition plate 300. The cabinet body 100 has a first receiving cavity 110 and a heat dissipation air inlet 120 and a heat dissipation air outlet 130 communicating with the first receiving cavity 110. The heat dissipation air inlet 120 is located at the lower part of the cabinet body 100, and the heat dissipation air outlet 130 is located at the upper part of the cabinet body 100. The heat dissipation fan 200 is located in the first receiving cavity 110. The first partition plate 300 is located in the first receiving cavity 110 and can divide the first receiving cavity 110 into a first cavity 111 and a second cavity 112, both of which are communicating with the heat dissipation air inlet 120 and the heat dissipation air outlet 130. The first partition plate 300 can also divide the heat dissipation fan 200 into a first driving area 210 communicating with the first cavity 111 and a second driving area 220 communicating with the second cavity 112. Both sides of the first partition plate 300 are used to support electrical components. The first partition plate 300 is used to support electrical components and can also separate the first receiving cavity 110 and the cooling fan 200 to reduce the size of the independent cavity, reduce the stagnation area of ​​airflow, and increase the airflow velocity. The cooling air inlet 120 is located at the lower part of the cabinet 100, and the cooling air outlet 130 is located at the upper part of the cabinet 100. When cooling, it can form a chimney effect. When the cooling fan 200 is running, the first driving area 210 can drive the airflow in the first cavity 111 to flow along one side of the first partition plate 300. Similarly, the second driving area 220 can drive the airflow in the second cavity 112 to flow along the other side of the first partition plate 300, which can fully dissipate heat from the electrical components on the first partition plate 300 and improve the heat dissipation effect.

[0033] Specifically, the heat dissipation air inlet 120 is located at the lower part of the cabinet 100, and the heat dissipation air outlet 130 is located at the upper part of the cabinet 100, which can form a bottom-in, top-out heat dissipation airflow direction, which is the same as the flow direction of hot air, and can form a chimney effect to improve the heat dissipation effect. The cooling fan 200 can be set close to the top of the cabinet 100, and the cooling fan 200 can be placed horizontally with the air blowing upward. The first partition plate 300 can vertically divide the first cavity inside the cabinet 100, and the first partition plate 300 can be located in the middle of the cooling fan 200, dividing the cooling fan 200 into a first driving area 210 and a second driving area 220. The first driving area 210 exhausts part of the first cavity 111, and the second driving area 220 exhausts part of the second cavity 112. Because the volume of the cavity is reduced, the stagnation area can be reduced, and the airflow can flow along both sides of the first partition plate 300. Electrical components can be installed on both sides of the first partition plate 300, which can increase the installation capacity, and the heat dissipation airflow can fully dissipate heat from the electrical components on both sides of the first partition plate 300.

[0034] Reference Figures 2 to 7In some embodiments of this utility model, the first partition plate 300 is vertically disposed on the first cavity 111, and the first cavity 111 and the second cavity 112 are disposed along the front-rear direction of the cabinet 100. Specifically, the first partition plate 300 can be disposed parallel to the front and rear side walls of the cabinet 100 to divide the first receiving cavity 110 into the first cavity 111 and the second cavity 112. The first cavity 111 can be located on the front side, and the second cavity 112 can be located on the rear side. It is understood that the cabinet 100 is generally set in a rectangular shape, and the setting direction of the first partition plate 300 allows the electrical components installed on the first partition plate 300 to face the front and rear sides, so as to facilitate installation and maintenance after the front and rear doors of the cabinet 100 are opened.

[0035] Reference Figures 2 to 7 In some embodiments of this utility model, a second partition plate 400 is also provided inside the cabinet 100. The second partition plate 400 is horizontally disposed at the lower part of the cabinet 100, and a first partition plate 300 is disposed at the top of the second partition plate 400. The second partition plate 400 can separate the lower part of the first receiving cavity 110 into a third cavity 113. The heat dissipation air inlet 120 is connected to the third cavity 113. The second partition plate 400 is provided with an air inlet mesh 410 that connects the third cavity 113 with the first cavity 111 and the second cavity 112. Specifically, the second partition plate 400 can be provided with an air inlet mesh 410 for airflow. The third cavity 113 separated by the second partition plate 400 is located below the first cavity 111 and the second cavity 112. Understandably, the cooling gas needs to enter the third chamber 113 through the cooling inlet 120 before entering the first chamber 111 and the second chamber 112. The third chamber 113 can serve as a filter chamber to filter out large dust particles. Therefore, components that are not easily damaged can be placed in the third chamber 113, and dust entering the first chamber 111 and the second chamber 112 can be reduced.

[0036] It is conceivable that a filter structure can be set in the third cavity 113, which can be a filter screen or a filter channel.

[0037] Reference Figures 3 to 4 In some embodiments of this utility model, the heat dissipation air inlet 120 is located on the bottom wall of the cabinet 100, and the heat dissipation air inlet 120 has a mesh structure. The bottom of the cabinet 100 is provided with support legs 140, which can create an air intake channel between the bottom wall of the cabinet 100 and the ground. Specifically, the support legs 140 can support the bottom wall of the cabinet 100, so that the bottom of the bottom wall can have an air intake channel to facilitate air intake, and the mesh structure can play a certain filtering role.

[0038] Reference Figures 2 to 5In some embodiments of this utility model, the cabinet 100 includes a main body 150 and an air hood 160. The air hood 160 is disposed on the top of the main body 150, and the air hood 160 and the main body 150 cooperate to separate the first receiving cavity 110 into an air outlet cavity 114. The main body 150 has a first cavity 111 and a second cavity 112. The top of the main body 150 is provided with an exhaust port 151 and a cooling fan 200. The cooling fan 200 blows air towards the air outlet cavity 114 through the exhaust port 151. The air hood 160 is provided with a heat dissipation exhaust port 130. Specifically, the air hood 160 can be configured as a hood structure with the opening facing downwards. After the air hood 160 is connected to the main body 150, the space between the air hood 160 and the main body 150 can serve as an air outlet 114. The top of the main body 150 can be connected to a cooling fan 200 and can be provided with an exhaust port 151 for the cooling fan 200 to blow air. The exhaust port 151 can connect the first cavity 111, the second cavity 112 and the air outlet 114. The heat dissipation exhaust port 130 of the air hood 160 is located on the side wall. The top of the air hood 160 is a closed structure, which can prevent dust from falling into the cabinet 100. The heat dissipation exhaust port 130 located on the side wall can also prevent dust from falling directly into the cabinet 100.

[0039] Reference Figures 5 to 6 In some embodiments of this utility model, the air outlet hood 160 has a first folded edge 161 and a second folded edge 162. The first folded edge 161 is located at the bottom of the side wall of the air outlet hood 160 and extends inward in the horizontal direction. The second folded edge 162 is located at the inner end of the first folded edge 161 and extends upward in the vertical direction. The side wall of the air outlet hood 160 is provided with a heat dissipation outlet 130, which has a mesh structure. The second folded edge 162 is arranged opposite to the heat dissipation outlet 130. Specifically, the mesh structure can reduce the entry of dust or foreign objects into the cabinet 100. By folding the side wall of the air outlet hood 160, the first folded edge 161 and the second folded edge 162 can be formed. The second folded edge 162 can play a blocking role. When the external airflow enters the third cavity 113, it needs to bypass the second folded edge 162, thereby achieving a certain filtering effect.

[0040] In some embodiments of this utility model, the projection of the second folded edge 162 toward the heat dissipation outlet 130 can cover the heat dissipation outlet 130. Specifically, in the horizontal direction, the second folded edge 162 can cover the heat dissipation outlet 130, and the horizontal airflow cannot directly cross the second folded edge 162 to enter the third cavity 113, which can further improve the filtration effect and reduce dust entering the cabinet 100.

[0041] Reference Figure 2In some embodiments of this utility model, the front side of the cabinet 100 is provided with a main cabinet door assembly 170, and the rear side of the cabinet 100 is provided with a detachable cover assembly 180. Specifically, the first cavity 111 can be used to house electrical components that require frequent operation or maintenance, and the cabinet door assembly 170 facilitates opening and operation. The second cavity 112 can be used to house electrical components that do not require frequent operation, and the detachable cover assembly 180 facilitates opening and maintenance, thereby reducing the manufacturing cost of the cabinet 100.

[0042] Reference Figure 2 In some embodiments of this utility model, the main cabinet door assembly 170 includes a first cabinet door 171 and a second cabinet door 172 arranged vertically. The first cabinet door 171 can open or close the first cavity 111, and the second cabinet door 172 can open or close the third cavity 113. Specifically, the third cavity 113 serves as a filter chamber and requires frequent opening for maintenance and cleaning. Therefore, the opening and closing components of the first cavity 111 and the third cavity 113 can be set independently, that is, the first cabinet door 171 opens and closes the first cavity 111, and the second cabinet door 172 opens and closes the third cavity 113. This reduces the opening and closing frequency of the first cavity 111, thereby protecting the electrical components inside the first cavity 111.

[0043] Reference Figure 2 In some embodiments of this utility model, the cover assembly 180 includes a first cover 181 and a second cover 182 disposed vertically. The first cover 181 can open or close the second cavity 112, and the second cover 182 can open or close the third cavity 113. Specifically, both the first cover 181 and the second cover 182 can be installed on the rear side of the cabinet 100 by fasteners or snap fasteners. The third cavity 113 serves as a filter chamber and requires frequent opening for maintenance and cleaning. Therefore, the first cover 181 and the second cover 182 can independently open and close the second cavity 112 and the third cavity 113 to reduce the frequency of opening the first cover 181 and protect the electrical components inside the second cavity 112.
