A flow distributor for a heat transfer device having a plurality of channels includes a sheath defining a plurality of distributor holes, each distributor hole configured to be in fluid communication with a respective channel inlet of each channel of the heat transfer device and an insert defining a plurality of fluid channels therein and a fluid inlet, each fluid channel in fluid communication with the fluid inlet. The insert is disposed within the sheath to seal the fluid channels with each fluid channel in fluid communication with a respective one of the distribution holes. The fluid inlet includes an inner inlet and an outer inlet radially outward from the inner inlet for mixing a fluid flow in the fluid inlet for evenly distributing fluid flow (e.g., a two phase flow) into the fluid channels of the insert and into each channel of the heat transfer device.

Flow distributor for heat transfer plate

A multi-layer heat exchanger includes a fluid layer defined by a first sheet and a second sheet, the fluid layer configured to route a fluid in a predominant flow direction. Also included is a fluid inlet port disposed proximate an inlet end region of the fluid layer, wherein the fluid inlet port is oriented to introduce the fluid into the fluid layer in a direction substantially perpendicular to the predominant flow direction, wherein the inlet end region of the fluid layer comprises a non-linear geometry. Further included is at least one fin segment disposed between the first sheet and the second sheet, wherein the at least one fin segment includes a first plurality of apertures proximate the inlet end region, the at least one fin segment consisting of a single, uniform fin segment.
