[0014] In summary, the present application includes at least one of the following beneficial technical effects:

[0015] 1. With the cooperation of the heat dissipation component and the driving component, when the temperature inside the cabinet is too high and needs to be dissipated, the driving motor is started, so that the driving motor drives the swing rod to swing back and forth through the crankshaft under the cooperation of the first connecting rod journal or the second connecting rod journal and the connecting groove. At the same time, with the cooperation of the driving groove and the driving column, the swing rod drives the first connecting rod to move back and forth in the vertical direction. With the cooperation of the first connecting rod, the second connecting rod and the third connecting rod, the heat dissipation channel and the air inlet channel respectively connected to the first air inlet and the second air inlet swing back and forth. When the heat dissipation channel swings, since its swing end has a faster linear speed than the other end, The flow velocity between the end of the swing end and the airflow increases, so that the air pressure at the swing end decreases to form negative pressure. The airflow at the other end of the heat dissipation channel, that is, the hot air at the top of the cabinet, is actively dissipated toward the outside of the cabinet through the heat dissipation channel and the first air outlet to perform active heat dissipation. In the process of the swing of the air inlet channel, the end close to the inside of the cabinet is the swing end. Similarly, the air outside the cabinet enters the inside of the box through the air inlet channel and the second air outlet due to pressure, forming a gas flow cycle between the heat dissipation channel, and because the hot air rises and the cold air falls away, the hot air is not easy to enter the inside of the cabinet again through the air inlet channel after flowing out of the outside of the cabinet, which further enhances the heat dissipation of the cabinet.

[0016] 2. By respectively arranging the first rubber ring and the second rubber ring on the heat dissipation channel and the air inlet channel, and respectively engaging with the first air inlet and the second air inlet, the noise generated by the heat dissipation channel and the air inlet channel during the swinging process is reduced;

[0017] 3. By setting one end of the air inlet channel close to the second air outlet in a constricted shape, when the air enters the cabinet through the air inlet channel, the air is compressed inside the air inlet channel and expands after entering the cabinet. Since the gas expands and absorbs heat, the heat in the cabinet can be absorbed, thereby reducing the temperature inside the cabinet;

[0018] 4. By setting up a protective cover, the direct entry of external dust or foreign objects into the cabinet can be reduced, and the protective covers corresponding to the first air outlet and the second air inlet are opened toward the top and bottom respectively to guide the dissipated hot air and reduce the re-entry into the cabinet.

[0027] The following is combined with Figure 1-7 This application is described in further detail.

[0028] The present application embodiment discloses an electrical cabinet with high heat dissipation performance. Figure 1-Figure 7 An electrical cabinet with high heat dissipation performance includes a cabinet body 1, one side of the cabinet body 1 is open and has a cabinet door 2, first installation cavities 3 are respectively opened inside the two opposite side walls of the cabinet body 1, and second installation cavities 4 that are respectively connected to the first installation cavities 3 on both sides are opened inside the top wall of the cabinet body 1, wherein heat dissipation components 5 are symmetrically arranged in the first installation cavities 3 on both sides, and a driving component 6 for driving the heat dissipation component 5 is arranged in the second installation cavity 4.

[0029] The heat dissipation assembly 5 includes a plurality of first heat dissipation units 7 located in the upper half of the cabinet 1 and a plurality of second heat dissipation units 8 located in the lower half of the cabinet 1. The first heat dissipation unit 7 includes a first air inlet 9 opened on the side wall of the first installation cavity 3 close to the interior of the cabinet 1 and connected to the interior of the cabinet 1, a first air outlet 10 opened on the side wall of the first installation cavity 3 close to the outside of the cabinet 1 and connected to the outer wall of the cabinet 1, and a heat dissipation channel 11 whose one end is clamped to the first air inlet 9 and the other end corresponds to the first air outlet 10.

[0030] The outer wall of the heat dissipation channel 11 is fixedly connected with a first rubber ring 15 extending around the circumference thereof, and the outer wall of the first rubber ring 15 is provided with a first clamping groove 16 extending around the circumference thereof, and the opening of the first air inlet 9 is clamped inside the first clamping groove 16, and the outer wall of the air inlet channel 14 is fixedly connected with a second rubber ring 17 extending around the circumference thereof, and the outer wall of the second rubber ring 17 is provided with a second clamping groove 18 extending around the circumference thereof, and the opening of the second air inlet 12 is clamped inside the second clamping groove 18, so as to reduce the noise generated by the heat dissipation channel 11 and the air inlet channel 14 during the swinging process.

[0031] In order to improve the heat dissipation, one end of the air inlet channel 14 close to the second air outlet 13 is set to be a constricted shape. In the process of space entering the cabinet 1 through the air inlet channel 14, the air is compressed inside the air inlet channel 14 and expands after entering the cabinet 1. Since the gas expands and absorbs heat, it can absorb the heat in the cabinet 1 and reduce the internal temperature of the cabinet 1.

[0032] The driving assembly 6 is used to drive the heat dissipation channel 11 and the air inlet channel 14 to swing synchronously. The driving assembly 6 includes connecting mechanisms 19 symmetrically arranged in the first installation cavities 3 on both sides, and driving mechanisms 20 arranged in the second installation cavity 4 and connected to the connecting mechanisms 19, wherein two groups of connecting mechanisms 19 are respectively provided corresponding to each group of heat dissipation assemblies 5, and are respectively arranged on both sides of each group of heat dissipation assemblies 5.

[0033] The connecting mechanism 19 includes a first connecting rod 21 hinged to the side walls of several heat dissipation channels 11 in sequence, a second connecting rod 22 hinged to the side walls of several air inlet channels 14 in sequence, a third connecting rod 23 whose two ends are respectively hinged to the first connecting rod 21 and the second connecting rod 22, an articulated seat 24 fixedly connected to the bottom surface of the second mounting cavity 4, and a swing rod 25 hinged to the articulated seat 24.

[0034] The hinge point between the hinge seat 24 and the swing rod 25 can be adjusted according to the swing amplitude of the heat dissipation channel 11 or the air outlet channel. The first connecting rod 21 is hinged to one end of the heat dissipation channel 11 close to the first air outlet 10, and the second connecting rod 22 is hinged to one end of the air outlet channel close to the second air outlet 13. The end of the swing rod 25 close to the first connecting rod 21 is provided with a driving groove 26, and the driving groove 26 extends along the length direction of the swing rod 25. The top of the first connecting rod 21 is fixedly connected to a driving column 27 extending into the driving groove 26.

[0035] The driving mechanism 20 is used to drive the other end of the swing rod 25 to swing back and forth. The driving mechanism 20 includes a crankshaft 29 rotatably supported on the bottom surface of the second mounting cavity 4 through a shaft seat 28, and a driving motor 30 connected to the crankshaft 29. The crankshaft 29 includes a main journal 31, a first connecting rod journal 32 and a second connecting rod journal 33 eccentrically arranged with the main journal 31, respectively, and the first connecting rod journal 32 and the second connecting rod journal 33 are respectively arranged on two opposite sides of the main journal 31. The other end of the swing rod 25 is provided with a connecting groove 34 extending along its length direction, and the first connecting rod journal 32 and the second connecting rod journal 33 are respectively arranged in the connecting grooves 34 of the swing rods 25 on both sides.

[0036] In order to reduce the situation of clothes or dust entering the cabinet 1, protective covers 35 are fixedly connected to the positions of the outer wall of the cabinet 1 corresponding to the first air outlet 10 and the second air inlet 12. The top of the protective cover 35 corresponding to the first air outlet 10 is open, and the bottom of the protective cover 35 corresponding to the second air inlet 12 is open, so as to guide the dissipated hot air and reduce the situation of re-entering the interior of the cabinet 1.

[0037] The implementation principle of an electrical cabinet with high heat dissipation performance in the embodiment of the present application is as follows:

[0038] With the cooperation of the heat dissipation component 5 and the driving component 6, when the temperature inside the cabinet 1 is too high and needs to be dissipated, the driving motor 30 is started, so that the driving motor 30 drives the swing rod 25 to swing back and forth through the crankshaft 29 under the cooperation of the first connecting rod journal 32 or the second connecting rod journal 33 and the connecting groove 34. At the same time, with the cooperation of the driving groove 26 and the driving column 27, the swing rod 25 drives the first connecting rod 21 to reciprocate in the vertical direction. With the cooperation of the first connecting rod 21, the second connecting rod 22 and the third connecting rod 23, the heat dissipation channel 11 and the air inlet channel 14 respectively connected to the first air inlet 9 and the second air inlet 12 swing back and forth. When the heat dissipation channel 11 swings, its swing end is relative to the other The linear speed at one end is faster, and the flow rate between the end of the swinging end and the airflow increases, so that the air pressure at the swinging end is reduced to form a negative pressure. The airflow at the other end of the heat dissipation channel 11, that is, the hot air at the top of the cabinet 1, is actively dissipated toward the outside of the cabinet 1 through the heat dissipation channel 11 and the first air outlet 10 to perform active heat dissipation. In the process of the swinging of the air inlet channel 14, the end close to the inside of the cabinet 1 is the swinging end. Similarly, the air outside the cabinet 1 enters the interior of the box through the air inlet channel 14 and the second air outlet 13 due to pressure, forming a gas flow cycle between the heat dissipation channel 11, and because the hot air rises and the cold air falls away, the hot air is not easy to enter the inside of the cabinet 1 again through the air inlet channel 14 after flowing out of the outside of the cabinet 1, thereby further enhancing the heat dissipation of the cabinet 1.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
