Abstract:
An apparatus for thermal management of an electronics module comprising:a first fan generating an inlet airflow and an exhaust airflow along a first fan axis; a second fan generating an inlet airflow and an exhaust airflow along a second fan axis, the second fan axis being substantially parallel to the first fan axis; a flow director disposed in the exhaust airflow of the first fan axis, the flow director redirecting the exhaust airflow of the first fan to the second fan along the second fan axis; a heat sink having a first portion disposed in at least one of the exhaust airflow of the first fan and the inlet airflow of the second fan, the heat sink having a second portion adapted for thermal coupling with the electronics module; and an enclosure surrounding the heat sink and the electronics module, the heat sink and the enclosure defining a first volume and a second volume, the first volume including the exhaust airflow of the first fan and the inlet airflow of the second fan, the second volume including the electronics module and being isolated from the airflows generated by the first fan and the second fan.
