The existing cabinet comprises a cabinet body bottom plate and a cabinet body side plate, an air inlet is usually formed in the part, close to the cabinet body bottom plate, of the cabinet body side plate, and external cold air and internal hot air circulate through the air inlet, so that the heat dissipation function is realized. In order to reduce the water vapor entering the cabinet, a waterproof member may be disposed at the air inlet. The existing waterproof component comprises a waterproof cavity, the waterproof cavity is provided with an air outlet, and outside cold air enters the waterproof cavity from the air inlet and then enters the cabinet from the air outlet. A single ventilation flow channel is formed in the waterproof cavity, and the side wall of the ventilation flow channel is of a straight plate type structure. Along the airflow flowing direction, a plurality of water baffles are arranged inside the ventilation flow channel at intervals, and the water baffles are perpendicular to the side wall of the ventilation flow channel or form a certain angle with the side wall of the ventilation flow channel. When external water drops enter the ventilation channel along with cooling gas, the external water drops are blocked and adsorbed by the water baffle plates arranged in a staggered mode, and the external water drops are converged into large water drops and then flow out downwards under the action of gravity.
