Description

A new type of electrical cabinet

technical field

The utility model relates to an electric cabinet, in particular to a novel electric cabinet.

Background technique

In terms of heat dissipation in traditional electrical cabinets, centrifugal fans are often used for forced air cooling to dissipate heat. The characteristics of centrifugal fans determine that the air outlet mode of the fans is vertical air outlet, that is, the air suction direction of the centrifugal fan is perpendicular to the direction in which the air is blown out. The air outlet method has the defects of large fluid resistance and low fan efficiency, and the above air outlet method cannot adapt to the heat dissipation of some electrical cabinets that require reverse air outlet (the air suction direction is opposite to the air blown out direction), and currently In some technical solutions, the centrifugal fan is placed on the top of the electrical cabinet (top outlet), and the external air duct is directly connected to the cabinet body, so the connection process is complicated and the air duct path is long.

A new type of electrical cabinet, including a cabinet main body, a cabinet door is provided on one side of the cabinet main body, and wall panels are provided on the other sides, and the characteristic is that: one side of the cabinet main body is provided with a number of windshields, and the windshields are provided with cooling fans. The windshield includes a side wall, the side wall is connected by several side plates to form an air channel, one end of the air channel is provided with a first fan mounting plate, and the other end has an air outlet, and the air outlet is provided with The second fan mounting plate, the first fan mounting plate is fixedly connected to the side wall, the second fan mounting plate is fixedly connected to the side wall through the connecting bar, and the first fan mounting plate is provided with an air inlet, and the side plates are opposite to each other. The first fan mounting plate is installed obliquely, and the angle θ formed by the side plate and the first fan mounting plate is an obtuse angle, so that the air inhaled by the air inlet is guided by the side plate and then blown out from the air outlet. An air hole is provided, and the air blown from the air outlet flows out through the air hole.

The first fan mounting plate is a square plate, the side wall is formed by connecting four side plates, and each side of the square plate is connected with a corresponding side plate.

The connecting strips are provided with four pieces, which are crossed and arranged in a cross structure.

There are several air holes on the wall.

The top surface of the main body of the cabinet is provided with a mounting bar, and a plurality of long holes are arranged on the mounting bar.

There are three windshields arranged in a straight line on one side of the main body of the cabinet.

The beneficial effects of the utility model are: the electrical cabinet adopts a windshield with side plates inclined relative to the first fan mounting plate, and the angle θ between the side plate and the first fan mounting plate is an obtuse angle, so that the air sucked by the air inlet After being guided by the side plate, it is blown out from the air outlet, changing the flow direction of the air, thereby changing the air outlet mode of the fan, shortening the fluid path, reducing resistance, and improving the use efficiency of the fan.

In addition, a plurality of long holes provided on the mounting bar can facilitate the external connection of the external heat dissipation air duct, and with the above heat dissipation structure, the path of the external heat dissipation air duct can be shortened and the structure is simple, thereby shortening the fluid path and improving heat dissipation efficiency.
