In order to achieve the purpose, the invention adopts the technical scheme that: a heat dissipation air duct structure of an electrical control cabinet comprises a main cabinet body, wherein a side door is correspondingly installed on the outer side of one side plate of the main cabinet body, the side door comprises a door main plate, the door main plate is parallel to and spaced from the corresponding side plate of the main cabinet body, the long edge direction of the door main plate is arranged along the vertical direction, and the peripheral edge of the door main plate is bent towards the main cabinet body to extend a circle of surrounding plate so as to enable the side door to be provided with an inner concave cavity; the edge of a side coaming of the side door in the short edge direction of the door main board is connected with the main cabinet body through a hinge; components are mounted on a side plate of the main cabinet body, and radiators of the components penetrate into the inner concave cavities of the side doors; and the lower part of the side door is provided with an air inlet, and the upper part of the side door is provided with an air outlet, so that the inner concave cavity of the side door becomes a vertically arranged natural ventilation heat dissipation air duct.
In the scheme, the edge of the coaming at the other side of the side door in the short edge direction of the door main board is bent inwards to extend a folded edge, at least two positioning blocks matched with the folded edge are arranged on the main cabinet body corresponding to the folded edge, and the two positioning blocks are arranged one above the other; and when the side door is closed, the two positioning blocks are positioned at the inner sides of the folded edges to block the folded edges, so that the closed state of the side door is locked.
The design principle and the working principle of the invention are as follows:
the invention adds a side door with an inward concave cavity on the side part of the main cabinet body of the electric control cabinet, when the side door is closed, a vertically arranged heat dissipation air duct is added beside the main cabinet body, the component with large heat productivity is arranged on the side plate of the main cabinet body at the side provided with the side door, and the radiator arranged on the component penetrates through the side plate and extends into the heat dissipation air duct. When the air-cooling device works, hot air emitted from the radiator rises upwards along the air duct and is exhausted from the air outlet at the top, cold air outside the air duct is sucked from the air inlet at the bottom due to airflow formed by continuously exhausting the hot air in the air duct, and the hot air is exhausted from the top to form a natural ventilation circulating system similar to a chimney.
Due to the application of the technical scheme, the invention has the following advantages:
1. the invention only uses a mechanical structure without any electric element, thereby achieving the effects of saving cost and energy;
2. the invention does not adopt any artificial ventilation cooling facility, thereby having no noise.
3. The heat dissipation air duct is an openable independent side door structure, and is convenient for regular cleaning and future maintenance.

Detailed Description
The invention is further described with reference to the following figures and examples:
example (b): referring to FIGS. 1-3:
the utility model provides an electric control cabinet's heat dissipation wind channel structure, electric control cabinet includes a main cabinet body 1, corresponds on the outside of a curb plate of this main cabinet body 1 and installs a side door 2. One side plate of the main cabinet body 1 can be any one of the left, right, front and rear side plates of the main cabinet body 1. In the figure, a side door 2 is mounted on a right side plate of a main cabinet 1, for example.
Referring to fig. 1-2, the side door 2 includes a door main board 21, the door main board 21 is parallel to and apart from the corresponding side plate of the main cabinet 1, and the long side direction of the door main board 21 is arranged along the vertical direction, and the periphery of the door main board 21 is bent towards the main cabinet to extend a circle of coaming 22, so that the side door 2 has an inner concave cavity. The side door 2 is connected to the main cabinet 1 by a hinge at an edge of a side panel 22 (as illustrated, an edge of a right side panel 22) in the short side direction of the door main plate 21. Components are mounted on a side plate of the main cabinet body 1, and radiators 3 of the components penetrate into the inner concave cavities of the side doors 2; and, there are air intakes 4 in the inferior part of the side door 2, and its upper portion has air outlets 5, become a vertical natural ventilation heat-dissipating wind channel 6 with the inner concave cavity of this side door 2.
The air inlet 4 is specifically an iron plate net with small holes which is embedded at the lower part of the side door 2, and the iron plate net with small holes can play a role in preventing dust and tiny animals. The air outlet 5 is composed of a vent hole arranged on a top enclosing plate of the side door 2, and the vent hole can prevent sundries from falling into the channel.
The side door 2 is a separate sheet metal part.
Referring to fig. 3, the edge of the other side panel 22 (i.e., the edge of the left side panel 22) of the side door 2 in the short side direction of the door main board 21 is bent inward to form a folded edge 221, at least two positioning blocks 11 matched with the folded edge 221 are arranged on the main cabinet body 1 corresponding to the folded edge 221, and the two positioning blocks 11 are arranged one above the other. When the side door 2 is closed, the two positioning blocks 11 are positioned at the inner sides of the flanges 221 to block the flanges 221, so that the closed state of the side door 2 is locked. That is, during the closing of the side door 2, the side door 2 has a certain elastic deformation force, so that the flange 221 passes over the two positioning blocks 11 and is caught by the positioning blocks 11. The preferred cone frustum shape of locating piece 11, its stub bar end links firmly with main cabinet body 1, and the preferred nylon that adopts in the material of locating piece.
When the air-cooling device works, hot air emitted from the radiator 3 rises upwards along the air duct 6 and is exhausted from the air outlet 5 at the top, cold air outside the channel is sucked from the air inlet 4 at the bottom due to airflow formed by continuously exhausting the hot air in the channel, and the hot air is exhausted from the top to form a natural ventilation circulating system similar to a chimney, so that no electric element is needed, the effects of saving cost and energy are achieved, and no noise is generated.
The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
