The invention relates to a mandatory cooling switch cabinet used for wind power generation equipment, which comprises a cabinet body, wherein a tubular air duct is formed vertically in the cabinet body; the upper end of the air duct is connected with an air outlet on the top of the cabinet; a fan is arranged at the air outlet; an opening at the lower end of the air duct is positioned in the middle of the cabinet body; a wallboard on the lower part of the cabinet body is provided with an air inlet grille; a bracket is arranged in the front side of the air duct, the front of the bracket is provided with easily heating elements, and the back of the bracket is provided with radiating fins; and the radiating fins are arranged in the air duct. The easily heating elements can be arranged on the bracket in a concentrated way and are mandatorily cooled by the radiating fins arranged in the air duct, so that the cooling effect on the elements in the cabinet can be greatly improved; and for high heating elements such as power units of the wind power generation equipment particularly, the operating reliability is improved through mandatory cooling.
Description
technical field [0001] The invention relates to a forced cooling switch cabinet for wind power generating equipment. Background technique [0002] Ordinary switchgear usually does not have a forced cooling device, and only relies on the natural circulation of air in the cabinet to dissipate the heat generated during the operation of the components in the cabinet. Even if fans are used to dissipate heat, there is no dedicated air duct to focus on cooling the key components. This makes it difficult to effectively dissipate the heat in the cabinet, and the temperature rise of the electronic components in the cabinet is relatively high during operation, which reduces their operational reliability and life. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a forced heat dissipation switchgear with good heat dissipation effect and high operation reliability. [0004] The forced heat dissipation switchgear of the presen...
