Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a closed power distribution cabinet. Background Art

[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the final equipment of the distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in occasions with relatively dispersed loads and fewer circuits. The motor control center is used in occasions with concentrated loads and more circuits. They distribute the electrical energy 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.

[0003] The existing referenceable Chinese utility model patent has a publication number of CN221201801U, which discloses a closed power distribution cabinet, including a power distribution cabinet, wherein dustproof and heat dissipation nets are arranged on both sides of the power distribution cabinet, and guide fixing rods are vertically arranged on the outer sides of each group of dustproof and heat dissipation nets, and cleaning brushes are arranged on the rods of the guide fixing rods, and a toggle rod is arranged at one end of the two groups of cleaning brushes. When the power distribution cabinet is working, the temperature generated inside can be effectively dissipated through the holes arranged on both sides, and the first net arranged on the outside can effectively isolate dust, and the second net can prevent dust from floating inside the cabinet when the dust on the surface of the net is subsequently cleaned. The power distribution cabinet can manually and quickly clean the surface of the net through the mechanism set up, and subsequently clean the dust inside the cabinet to the inside of the box below, and then quickly take it out, which is very convenient.

[0004] In order to dissipate heat, existing closed distribution cabinets have an array of openings on the outer shell for air circulation to remove the heat inside the distribution cabinet. It cannot be completely closed, and dust will enter the cabinet through the openings for heat dissipation. At the same time, this method has low heat dissipation efficiency. Utility Model Content

[0015] Compared with the prior art, the utility model provides a closed power distribution cabinet, which has the following beneficial effects:

[0016] 1. The utility model sets a heat spreader, which is symmetrically installed on the front and back sides of the copper column. The cabinet is provided with a groove that is embedded with the copper column. The copper column is equidistantly installed inside the cabinet up and down. The right end of the copper column is fixedly connected to the connecting copper plate. The heat spreader is a vacuum cavity with a microstructure on the inner wall.

The heat inside the cabinet can be discharged while ensuring that the cabinet is in a completely closed state after the cabinet door is closed, thereby preventing dust from entering the interior of the cabinet through the hole array used for heat dissipation.

[0033] Specifically, the cabinet body 1 can protect the internal circuit. The hinge 11 can facilitate the rotation of the cabinet door 12. The cabinet door 12 can close the left end of the cabinet body 1. The copper columns 13 can facilitate heat conduction. The heat pipes 14 can facilitate the transfer of heat to the copper columns 13. The partition 15 can close the opening on the right side of the cabinet body 1 and play a certain role in heat conduction.

A groove for fitting with the copper column 13 is provided inside the cabinet body 1. The copper columns 13 are installed at equal distances up and down inside the cabinet body 1. The right end of the copper column 13 is fixedly connected to the connecting copper plate 16. The heat pipe 14 is a vacuum cavity with a micro-structure on its inner wall. When heat is conducted from the heat source to the evaporation area, the coolant in the cavity starts to vaporize when heated in a low-vacuum environment.

By conducting the heat inside the cabinet body 1 to the connecting copper plate 16 located on the back of the cabinet body 1 through the copper column 13, it is possible to export the heat inside the cabinet body 1 while ensuring that the cabinet body 1 is completely closed after the cabinet door 12 is closed, thereby preventing dust from entering the inside of the cabinet body 1 through the heat dissipation opening array.
