[0013] This utility model discloses a frequency converter cabinet with temperature control function. By installing a connecting frame and two exhaust devices on the upper surface of the bottom frame, it can draw outside air into the frequency converter cabinet through two ventilation ducts. Through the exhaust duct and exhaust device installed on the upper surface of the cabinet, it can expel hot air from the cabinet, thereby enabling rapid air circulation and cooling of the components inside the cabinet.
