Ventilation and heat dissipation apparatus and electromechanical device

Abstract

A ventilation and heat dissipation apparatus and an electromechanical device is provided. The apparatus includes: a main frame configured to connect to a device to be ventilated and cooled, and a ventilation and heat dissipation assembly located inside the main frame. The ventilation and heat dissipation assembly includes a waterproof unit, an external ventilation unit, and an internal ventilation unit. The waterproof unit is located between the external ventilation unit and the internal ventilation unit, and the external ventilation unit and the internal ventilation unit are arranged in a staggered manner. A bottom of the waterproof unit is provided with a drainage hole. External rainwater is prevented from entering the device, outside air enters the main frame through the external ventilation unit, and heat generated during operation of the device enters the main frame through the internal ventilation unit, for heat exchange.
