Low-carbon energy-saving dual-system heat pipe integrated cabinet

The utility model provides a low-carbon energy-saving dual-system heat pipe integrated cabinet. Comprising a cabinet body unit, a composite air conditioning unit located in the cabinet body unit, a passive emergency cooling unit and an equipment installation area. The composite air conditioner unit comprises two independent refrigerating systems including a heat pipe module and a compression module, the heat pipe module is a preferential refrigerating system, and the compression module is a supplementary refrigerating system. Hot air enters the heat pipe evaporator from the equipment mounting area for primary cooling, and if the air subjected to primary cooling does not meet the set air outlet temperature, the air enters the compression evaporator for secondary cooling. The composite air-conditioning unit has three operation modes: 1) a heat pipe operation mode; 2) a mixed operation mode; and 3) a compressor operation mode. When the composite air conditioning unit is shut down due to power failure, the passiv
