    摘要： To provide a heat exchange unit capable of suppressing an increase in manufacturing cost by preventing damage to a flat tube caused by sliding against other members. A utilization unit (3) includes a utilization heat exchanger (32) and a first member (34). In the utilization heat exchanger (32), a plurality of flat tubes (32a) are stacked at predetermined intervals in a thickness direction by a heat transfer fin (32b). The first member (34) is attached to the utilization heat exchanger (32). The first member (34) includes a body (34a) and a protrusion portion (34b) protruding from the body (34a). The protrusion portion (34b) is inserted between flat tubes (32a) adjacent to each other.

    摘要： Provided is a cascade refrigeration cycle apparatus that is highly efficient. The cascade refrigeration cycle apparatus includes a fan (40), a first cycle, a second cycle, and a cascade heat exchanger. In the first cycle, a first refrigerant having a critical point of 40°C or higher circulates. The first cycle includes a condenser (104) in which air supplied by the fan and the first refrigerant exchange heat. In the second cycle, carbon dioxide as a second refrigerant circulates. The second cycle includes a first heat exchanger (26) functioning as a radiator in which air supplied by the fan and the second refrigerant exchange heat. In the cascade heat exchanger, the first refrigerant and the second refrigerant exchange heat. The condenser is disposed on a windward side of the radiator in an airflow direction (D) that is a direction of an airflow generated by the fan.
