Solar power is a new type of energy that is rich and will not be exhausted, safe, clean, and will not threaten human beings and damage the environment. Various electrical control cabinets are needed in solar power generation, and the operation of electrical appliances in the control cabinet will emit Temperature, in order to ensure that the control cabinet can work normally, it is necessary to cool the control cabinet. In China, the place with the most abundant sunlight is the desert. The desert has the characteristics of large dust and dry climate. The ventilation effect is good, the manufacturing cost is low, and the disadvantage is that it is easy to enter the sand and dust, and it needs to be cleaned regularly or irregularly. Second, it is a semi-closed type, and an air filter device is installed outside to filter out the sand and dust, and then pass the filtered air through. The cooling device is cooled, and the cooled air is sent to the electrical control cabinet. The hot air in the electrical cabinet is exhausted by the exhaust fan.
