The upper and lower parts of the partition are equipped with ventilation fans. When heating the dehumidification module or the heat dissipation dehumidification module, the hot air or cold air can be quickly mixed and filled with the power distribution cabinet through the circulation of two ventilation fans; when the temperature and humidity in the power distribution cabinet reach the preset values, the power distribution When condensation begins to occur in the cabinet, the humid air in the power distribution cabinet is heated and dried by the heating and dehumidification module and discharged through the exhaust holes on the top of the power distribution cabinet, and then the cooling and dehumidification module is used to keep the low temperature in the power distribution cabinet, and the power distribution cabinet is The temperature outside the cabinet is the same to avoid the recurrence of condensation.
