The length of the air outlet mechanism 602 is the same as the width of the back panel opening of the power distribution cabinet 1 .

Install the power equipment on the heat-conducting plate 2, and conduct the heat to the radiator 3 installed on the back through the heat-conducting plate 2. After the distribution box is installed, the natural wind blows on both sides of the distribution cabinet 1 and will follow the distribution cabinet. 1 moves to the rear fins 5, and then blows out from the air outlet mechanism 602 through the fins 5, the fin slots 402, and the ducts 601 in sequence, and the blown air will be blown out from the bottom end of the power distribution cabinet 1 Blow up, take away the heat on the radiator 3 in the process of blowing upward, because the heat of the radiator 3 will naturally dissipate upward in the process of heat dissipation, and the air flowing through the radiator 3 is improved by providing upward flowing wind flow rate, so as to enhance the heat dissipation efficiency of the radiator 3 .
