Abstract:
1. A blowerless heat exchanger apparatus, comprising: a plurality of fins spaced apart from each other, each fin of the plurality of fins defining a plurality of micro-jet nozzles on a surface of the respective fin, wherein the plurality of micro-jet nozzles point to an air flow direction in order to directly propel air by entrainment; a plurality of air channels embedded in the plurality of fins, at least one air channel of the plurality of air channels being in fluidic connection with at least one micro-jet nozzle of the plurality of micro-jet nozzles; and an air compressor configured to provide compressed air to the plurality of micro-jet nozzles, wherein the plurality of micro-jet nozzles are configured to induce entrainment flow and turbulence to enhance a heat transfer coefficient of the heat exchanger apparatus, wherein a first mass flow rate from the air compressor is smaller than a second mass flow rate of the entrainment flow.
