Control cabinet for air conditioner assembly and air conditioner assembly

The invention discloses a control cabinet for an air conditioner assembly and the air conditioner assembly, and the control cabinet comprises a cabinet body which is internally provided with a mounting cavity; the frequency converter is arranged in the mounting cavity, and a first cooling opening and a second cooling opening are formed in the frequency converter; the air duct component is arranged on the cabinet body and surrounds at least part of the periphery of the mounting cavity, an air duct is formed in the air duct component, an inlet of the air duct communicates with the first cooling opening, and an outlet of the air duct communicates with the second cooling opening; and at least part of the heat exchange component is contained in the air duct and used for conducting heat exchange on airflow in the air duct. According to the control cabinet, the frequency converter and the heat exchange component are arranged in the air duct, the heat exchange component can exchange heat with the air flow in the air duct, the temperature of the air flow in the air duct is reduced, the low-temperature air flow can exchange heat with the frequency converter, heat dissipation of the frequency converter is achieved, heat dissipation holes do not need to be formed in the cabinet body, and the cost is reduced. And the safety and the reliability of the control cabinet are improved.
