Title: ENHANCED HEAT TRANSFER IN PRINTED CIRCUIT HEAT EXCHANGERS
Abstract:
The disclosure includes a heat exchanging apparatus, comprising a heat exchanger plate comprising a plurality of flow passages, and wherein each flow passage comprises at least one surface feature configured to change the flow characteristics of a linear flow along an axis of flow for the flow passage. The disclosure further includes a method of constructing a heat exchanger, comprising using additive manufacturing to form a first plate having a plurality of flow passages, wherein each of the flow passages has one or more integrally formed surface features, wherein the integrally formed surface features are configured to change the flow characteristics of a fluid flowed linearly along an axis of flow for the flow passage.
