Air-cooled heat exchanger and electronic device with same

摘要

An air-cooled heat exchanger includes a casing, a first heat-exchanging core, a second heat-exchanging core, a first internal driving device, a second internal driving device and an external driving device. The first internal driving device is used for driving a first internally-circulated airflow to flow along a first internal circulation path. The second internal driving device is used for driving a second internally-circulated airflow to flow along a second internal circulation path. The external driving device is used for driving a first externally-circulated airflow to flow along a first external circulation path and driving a second externally-circulated airflow to flow along a second external circulation path. The first heat-exchanging core is configured to perform heat exchange between the first internally-circulated airflow and the first externally-circulated airflow. The second heat-exchanging core is configured to perform heat exchange between the second internally-circulated airflow and the second externally-circulated airflow.
