Technical Field

[0001] The utility model relates to the field of switch cabinets, and in particular to an easily disassembled and assembled low-voltage complete switch cabinet with high heat dissipation. Background Art

[0002] Low-voltage switchgear is an electrical device used to control, distribute and protect low-voltage power systems. Its characteristics are to provide power control, protection, conversion and distribution functions at a lower voltage (usually AC rated working voltage of 660V and below). Low-voltage switchgear usually contains a variety of components, such as circuit breakers, contactors, relays, meters and some auxiliary control and monitoring equipment. These devices can be assembled according to a predetermined line scheme to form a complete power distribution device.

[0003] Although there are many different low-voltage switch cabinets on the market, such as the existing drawer-type low-voltage switch cabinets, the existing drawer-type low-voltage switch cabinets usually use air cooling to achieve the corresponding heat dissipation effect by exchanging the gas inside the cabinet with the gas outside the cabinet. In this way, during the heat dissipation process, the electrical control components inside the cabinet need to be in direct contact with the outside. If the air is humid and carries dust, it will easily corrode the electrical control components and circuits inside the cabinet over time, thereby affecting the life of the electrical control components and circuits.

[0004] Therefore, it is very necessary to invent a low-voltage complete switch cabinet with high heat dissipation that is easy to disassemble and assemble. Utility Model Content

[0025] It should be noted that the connection structure between the support plate 5, the slide rail and the drawer 6 adopts the existing technology, such as the drawer structure in the drawer-type low-voltage distribution cabinet in the existing technology, so it will not be described in detail here.

[0026] A plurality of connecting pipes 41 are evenly and fixedly installed on the inner side of one of the side cover plates 4 from top to bottom. The connection pipes 41 facilitate the connection between the support plate 5 and the side cover plate 4. A plurality of air holes 42 are evenly and penetrated through the side cover plate 4 from top to bottom. The air holes 42 correspond to the connecting pipes 41 one by one.

The air holes 42 facilitate the external air to enter the cavity 51 through the connecting pipe 41, or the gas in the cavity 51 is discharged from the air holes 42 through the connecting pipe 41.

[0027] It should be noted that the air holes 42 can be connected together through a pipe, and then connected to an external fan through the pipe, so that the fan can simultaneously deliver cold air to the air holes 42 to quickly dissipate heat inside the rail cabinet.

A wind slot is provided on the front side of the support plate 5.

[0031] A refrigerant is stored inside the cavity 54 , and the refrigerant occupies half of the volume of the cavity 54 . Through the provision of the refrigerant, heat can be exchanged with the heat-conducting column 53 after the heat-conducting column 53 absorbs heat.

[0032] A sealing gasket is fixedly installed at the contact portion between the drawer 6 and the corresponding support plate 5. The setting of the sealing gasket can prevent dust from entering the cabinet body from the contact portion between the drawer 6 and the corresponding support plate 5.

[0033] In this embodiment, in the later use, the external air can enter the cavity 1 51 through the air hole 42, the connecting pipe 41, and the hole 52, and then contact the heat-absorbing heat-conducting column 53 and the fin 55 to perform heat exchange, and the gas after heat exchange can be discharged from the wind slot; at the same time, the external air can enter the cavity 1 51 through the wind slot, and then contact the heat-absorbing heat-conducting column 53 and the fin 55 to perform heat exchange, and the gas after heat exchange can be discharged from the hole 52, the connecting pipe 41 and the air hole 42;

[0034] In this way, during the entire heat dissipation process, the electrical control components and circuits inside the cabinet will not come into contact with the air, making the overall system safer and more reliable, and greatly improving the service life of the electrical control components and circuits.
