The temperature conducting plates will lower the ambient air. After the cold air motor is started, it will drive the cold air blades to rotate, and the cold air in the temperature conducting plates will be blown into the air guide ports. The air guide ports will guide the cold air into the air guide ducts, and the cold air will be discharged into the heat dissipation distribution cabinet through the air outlets, so as to lower the temperature of various positions inside the heat dissipation distribution cabinet, thereby avoiding the problem that the existing distribution cabinet generally uses a fan to blow air into the distribution cabinet for heat dissipation.

[0026] 2.
