主权项 1. A device for cooling an electrical cabinet having an interior, a lower end and an upper end, comprising: a hollow upright beam having a lower end, an upper end, a cavity inside, an air inlet at the lower end, and an air outlet at the upper end, the upright beam supporting the electrical cabinet on a side of the upright beam; a first flow connection formed between the interior of the electrical cabinet and the cavity of the upright beam at a level of the lower end of the electrical cabinet; a second flow connection formed between the interior of the electrical cabinet and the cavity of the upright beam at a level of the upper end of the electrical cabinet; and a sealing element at an intermediate level between the first and second flow connections to block the cavity of the upright beam, the device thus configured to pass airflow, the airflow entering from outside through the air inlet, passing through the electrical cabinet, and exhausting outside through the air outlet at the upper end.
