Connected, the two ends of the air outlet hood are respectively connected with the air outlet and the air outlet, and the air inlet hood and the air outlet hood are respectively provided with a suction fan and an exhaust fan.

Install the electrical equipment on the front of the mounting plate, the heat of the electrical equipment will evaporate to the heat dissipation ribs, and the suction fan and exhaust fan are turned on at the same time, so the air is drawn from the air inlet, enters the heat dissipation channel through the air inlet hole, and dissipates heat from the heat dissipation ribs , so while the power equipment dissipates heat, it can also provide heat dissipation for the heat dissipation ribs, so as to improve the overall heat dissipation effect.

Preferably, the heat dissipation ribs are also fixed with mounting ribs arranged transversely and parallel to the mounting plate, and the mounting ribs are provided with mounting holes for installing electrical equipment.

The installation rib is convenient for installing electrical equipment, and also has a certain wind-shielding function.

As a preference, several threading holes are provided on the installation plate, an inspection port is provided on the back plate, and an inspection door is hinged on the inspection port.

Therefore, it is also possible to thread the lines of the electric equipment on the threading holes and arrange them through the maintenance door.

Preferably, the heat dissipation ribs, mounting ribs and windshield ribs are integrated and made of aluminum.

Compared with the prior art, the utility model has the following advantages:

Install the electrical equipment on the front of the mounting plate, the heat of the electrical equipment will evaporate to the heat dissipation ribs, and the suction fan and exhaust fan are turned on at the same time, so the air is drawn from the air inlet, enters the heat dissipation channel through the air inlet hole, and dissipates heat from the heat dissipation ribs , so while the power equipment dissipates heat, it can also provide heat dissipation for the heat dissipation ribs, so as to improve the overall heat dissipation effect.

detailed description

The following are specific embodiments of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model is not limited to these embodiments.

As shown in Fig. 1, Fig. 2 and Fig. 3, the heat dissipation type power cabinet includes a cabinet body 1, and a vertically arranged backboard 11 is arranged on the rear side of the cabinet body 1, and is fixed in the cabinet body 1, and is connected to the backboard. The board 11 is parallel to the installation board 2, and the electric equipment is installed on the front of the installation board 2. A number of air inlets 12 and air outlets 13 are respectively provided on both sides of the back board 11. The front of the installation board 2 is provided with a number of heat dissipation ribs arranged horizontally and parallel to each other. 21. The heat dissipation ribs 21 are distributed longitudinally at intervals, and also include two windshield ribs 22 arranged on the front of the mounting plate 2, and the two ends of several heat dissipation ribs 21 are connected with the windshield ribs 22, and the heat dissipation ribs 21 and the windshield ribs 22 are on the The front of the mounting plate 2 forms a number of heat dissipation channels arranged transversely. The corresponding positions of the mounting plate 2 and the two ends of the heat dissipation channels are respectively provided with air inlet holes 23 and air outlet holes 24. The wind cover 14 and the wind outlet cover 15, the two ends of the air inlet cover 14 communicate with the air inlet 12 and the air inlet hole 23 respectively, and the two ends of the air outlet cover 15 communicate with the air outlet 13 and the air outlet 24 respectively, and the air inlet cover 14 A suction fan and an exhaust fan are respectively arranged in the air outlet cover 15.
