Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
As shown in fig. 1, an electrical control cabinet comprises a cabinet body 1 and a mounting frame arranged in the cabinet body 1, wherein an exhaust chamber 4 is arranged at the top of the cabinet body 1, an exhaust port is arranged in the exhaust chamber 4, an exhaust fan 5 is further arranged at the top of the cabinet body 1, an inlet of the exhaust fan 5 is communicated with the exhaust port, an air outlet of the exhaust fan 5 is communicated with the atmosphere, an air inlet chamber 6 is arranged at the bottom of the cabinet body 1, and an air inlet communicated with the atmosphere is arranged on the air; the mounting bracket is including vertical frame 2 and the horizontal frame 3 that is hollow form respectively, and vertical frame 2 is vertical setting in the internal both sides of cabinet respectively, and the bottom of the vertical 2 tops of frame intercommunication exhaust chambers 4 of one side, the top of the vertical 2 bottoms intercommunication inlet chambers 6 of the vertical frame of opposite side, the both ends of horizontal frame 3 communicate the vertical frame 2 of both sides respectively.
In practice, the bottom of the longitudinal frame 2 on one side is arranged at the bottom of the inner side of the cabinet body 1 and is closed, and the top of the longitudinal frame 2 on the other side is arranged at the top of the inner side of the cabinet body 1 and is closed. When the exhaust fan 5 works, air outside the cabinet body 1 is exhausted from the air inlet chamber 6 through the mounting frame and the exhaust chamber 4 under the action of the exhaust fan 5, and in the process, the air in the cabinet body 1 and the air in the mounting frame exchange heat through the mounting frame body to finish heat dissipation. The heat exchange work cooperation principle of the cabinet body 1 and the mounting rack is similar to that of a shell-and-tube heat exchanger (the work principle of the shell-and-tube heat exchanger is that the temperature of substances in a tube side is different from that of substances in a shell side, and heat exchange is carried out in a heat conduction mode). In this embodiment, the air temperature in the mounting bracket is ambient temperature, and the temperature in the cabinet is higher than ambient temperature, and the heat in the cabinet body 1 passes through the air in mounting bracket transmission to mounting bracket and the mounting bracket, and the air exhauster 5 accelerates the flow of the air in the mounting bracket for the air temperature in mounting bracket and it reduces to ambient temperature, thereby realizes the radiating effect with higher speed to the internal temperature of the cabinet body 1. The inside and the 1 inside nonconnection of cabinet body of mounting bracket when realizing the heat dissipation, improve dustproof effect.
In this embodiment, the transverse frame 3 or the longitudinal frame 2 is respectively a hollow plate-like structure as shown in fig. 2, or respectively a hollow tubular structure as shown in fig. 3. In practice, multiple layers are transversely added, longitudinal frames 2 can be additionally arranged between the longitudinal frames 2 on the two sides according to the size of the actual cabinet body 1, and the middle longitudinal frame 2 is communicated with the longitudinal frames 2 on the two sides through the transverse frame 3.
In order to facilitate the fixation, the longitudinal frame 2 is provided with a connecting sheet which is provided with a connecting hole. The electrical equipment for electrical control is placed on the transverse direction and is connected and fixed with the connecting sheet through bolts.
Preferably, the rear side of the cabinet body 1 is uniformly provided with a plurality of radiating fins 7, and the radiating fins 7 increase the radiating area of the side wall of the cabinet body 1, so that the radiating effect is improved.
In another embodiment, the longitudinal frames 2 at two sides in the cabinet body 1 are respectively arranged at a certain distance from the side wall of the cabinet body 1; the lateral wall outside of the cabinet body 1 both sides has radiating fin 7 respectively the equipartition, strengthens the radiating effect of both sides lateral wall through radiating fin 7, avoids vertical frame 2 to press close to the lateral wall and influence the heat dissipation of lateral wall.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
