[0002] The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits; the motor control center is used in places where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load. During the operation of the equipment, heat will be generated, and it is necessary to dissipate the heat inside the equipment to ensure stable operation of the equipment.

[0003] When using traditional distribution cabinet equipment, passive heat dissipation is often adopted, or a cooling fan is installed. However, in some humid weather, the air contains more moisture. At this time, when the air is directly introduced into the inner cavity of the equipment, the air with high humidity will cause the equipment to short-circuit or even cause a fire, thus affecting the safe operation of the equipment.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 A heat dissipation structure for a low-voltage power distribution cabinet comprises a cabinet body 1, a cabinet door 2 is rotatably connected to the outer wall of the cabinet body 1, a fixing plate 3 is fixedly mounted on the outer wall of the cabinet body 1, an air inlet pipe 4 is fixedly mounted on the outer wall of the air inlet pipe 4, a drying bin 5 is fixedly mounted on the outer wall of the drying bin 5, a U-shaped plate 6 is rotatably connected to the outer cavity of the U-shaped plate 6, a pull rod 7 is movably sleeved on the inner cavity of the U-shaped plate 6, a pressure plate 8 is fixedly mounted on the outer edge of the pull rod 7, a telescopic spring 9 is movably sleeved on the outer wall of the pull rod 7, an adsorption plate 10 is installed in the inner cavity of the drying bin 5, a connecting pipe 11 is fixedly mounted on the outer wall of the connecting pipe 11, an air inlet bin 12 is fixedly mounted on the outer wall of the connecting pipe 11, a filter screen 14 is fixedly mounted on the outer wall of the air inlet bin 12, a heat dissipation fan 13 is fixedly mounted on the inner cavity of the air inlet bin 12, an exhaust pipe 15 is fixedly mounted on the outer wall of the fixing plate 3, and a one-way door 16 is rotatably connected to the outer wall of the exhaust pipe 15.

[0021] By means of the air intake bin 12, the cooling fan 13 and the filter 14, the external air can be drawn into the inner cavity of the air intake bin 12 under the action of the cooling fan 13, and enter the inner cavity of the connecting pipe 11 and the drying bin 5 through the air intake bin 12, and then enter the inner cavity of the cabinet 1 through the air intake pipe 4 under the processing of the adsorption plate 10.

[0022] In a preferred embodiment, the outer wall of the pull rod 7 passes through the outer wall of the U-shaped plate 6 and is connected to the outer wall of the pressure plate 8 , and the two ends of the telescopic spring 9 are respectively connected to the outer walls of the pressure plate 8 and the U-shaped plate 6 .

[0023] By means of a pull rod 7 arranged in the inner cavity of the U-shaped plate 6 and a telescopic spring 9 arranged on the outer wall of the pull rod 7, the pull rod 7 and the pressure plate 8 can be moved inwardly under the action of the telescopic spring 9, so that the outer wall of the pressure plate 8 fits against the outer walls of the drying bin 5 and the adsorption plate 10, thereby achieving fixed installation of the adsorption plate 10 under the action of the pressure plate 8.

[0024] In a preferred embodiment, there are two U-shaped plates 6 , and the two U-shaped plates 6 are respectively installed on both sides of the outer wall of the drying chamber 5 .

[0025] By means of the U-shaped plate 6 arranged on the upper and lower sides of the outer wall of the drying chamber 5, and the pull rod 7 and the pressure plate 8 in the inner cavity of the U-shaped plate 6, the adsorption plate 10 can be fixed under the action of the pull rod 7 and the pressure plate 8. When the adsorption plate 10 needs to be replaced, it is only necessary to pull the pull rod 7 and rotate the U-shaped plate 6, so that the U-shaped plate 6 can drive the pull rod 7 and the pressure plate 8 to leave the outer wall of the adsorption plate 10, and the adsorption plate 10 can be easily replaced.

[0026] In a preferred embodiment: activated carbon wrapped in gauze is installed in the inner cavity of the adsorption plate 10, and a rubber anti-slip pad is fixedly mounted on the outer wall of the pressing plate 8 on the side close to the adsorption plate 10.

[0027] By filling the inner cavity of the adsorption plate 10 with activated carbon, the moisture in the air passing through the inner cavity of the drying chamber 5 is absorbed under the action of the activated carbon, so that the air remains in a relatively dry state after passing through the drying chamber 5, thereby preventing moisture in the air from entering the inner cavity of the cabinet 1.

[0028] In a preferred embodiment, the shape of the outer wall of the one-way door 16 matches the shape and size of the outer wall of the exhaust pipe 15 , and the inner cavities of the exhaust pipe 15 and the air inlet pipe 4 are both connected to the inner cavity of the cabinet 1 .

[0029] By setting a one-way door 16 on the outer wall of the exhaust pipe 15, the one-way door 16 can only be flipped outward under the action of the exhaust pipe 15 and cannot be rotated inward, so that the one-way door 16 can cover the outer wall of the exhaust pipe 15 under the action of gravity. At this time, under the obstruction of the one-way door 16, the air in the inner cavity of the exhaust pipe 15 can only move outward.

[0030] In a preferred embodiment, a controller is disposed on the outer wall of the cabinet 1 , and the controller is electrically connected to the cooling fan 13 , and the top of the fixing plate 3 is in contact with the bottom of the drying chamber 5 .

[0031] By means of a controller arranged on the outer wall of the cabinet 1, the cooling fan 13 is controlled under the action of the controller, so that the rotation direction and rotation speed of the cooling fan 13 can be controlled, thereby better drawing external air into the inner cavity of the cabinet 1 under the action of the cooling fan 13.

[0032] Working principle: During the use of the above-mentioned equipment, heat will be generated during the normal use of the cabinet 1. At this time, the cooling fan 13 is started by the controller. At this time, the external air can be drawn into the inner cavity of the air inlet bin 12 under the action of the cooling fan 13, and enter the inner cavity of the drying bin 5 through the connecting pipe 11, and adsorb the moisture in the air under the action of the adsorption plate 10 in the inner cavity of the drying bin 5, so that the air entering the inner cavity of the cabinet 1 can be kept in a relatively dry state, and the air pressure in the inner cavity of the cabinet 1 will increase, so that it wants to escape outward. At this time, the one-way door 16 will be pushed open under the action of pressure, and the air in the inner cavity of the cabinet 1 will form a circulation state, thereby playing a heat dissipation effect on the equipment in the inner cavity of the cabinet 1 during the circulation process, and the adsorption plate 10 will be worn during use. When the adsorption plate 10 needs to be replaced, it only needs to pull the pull rod 7 and rotate the U-shaped plate 6. At this time, the pressure plate 8 can be separated from the outer wall of the adsorption plate 10, and the adsorption plate 10 can be replaced very conveniently at this time.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
