Enhanced Heat Transfer In Plate-Fin Heat Exchangers

摘要

This 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 integral surface features, wherein the integral surface features are configured to change the flow characteristics of a fluid flowed linearly along an axis of flow for the flow passage.

主权项

1. A heat exchanging apparatus, comprising:
a heat exchanger plate comprising a plurality of fins defining a plurality of flow passages for the heat exchanger plate, wherein at least one fin extends into an inlet section as a distributor fin, and wherein the distributor fin comprises a contiguous arm for directing flow from the inlet plenum into at least one flow passage.
