The working mode of the invention is as follows:
when the outdoor temperature is higher than 30 ℃, a special supply pipeline is opened, the special supply pipeline refers to a pipeline specially supplying water for a plurality of water pipes, an electric control valve is opened simultaneously, water is sprayed upwards through a spraying plate to moisten a heat conducting fin, external air enters through an air inlet and then needs to pass through a channel formed by a heat conducting plate, and during passing, hot air entering from the outside is cooled and then is upwards conveyed into a cabinet body through a fan to cool electrical equipment in the cabinet body.
The invention has the beneficial effects that:
1) the cabinet body is separated from the ground by adopting the base, so that the hot air flow on the ground is prevented from directly acting on the cabinet body;
2) spraying water mist which is contacted with the heat conducting fins upwards through the spraying plate, cooling the heat conducting fins by the water mist, cooling the heat conducting fins after air flow entering from the outside is contacted with the heat conducting fins, and then sending the air flow into the cabinet body to realize cooling of the inside of the cabinet body;
3) the cabinet body can upwards separate, is convenient for clear up the inside accumulational particulate matter of base, clears up the dirt of condensing on the conducting strip simultaneously, ensures that this product keeps better heat dispersion.
4) The structure of this product is comparatively simple, and the cost is comparatively cheap, is fit for using widely.
