FLUID HEAT EXCHANGER CONFIGURED TO PROVIDE A SPLIT FLOW

摘要

A fluid heat exchanger can define a plurality of microchannels each having a first end and an opposite end and extending substantially parallel with each other microchannel. Each microchannel can define a continuous channel flow path between its respective first end and opposite end. A fluid inlet opening for the plurality of microchannels can be positioned between the microchannel first and opposite ends, a first fluid outlet opening from the plurality of microchannels can be positioned adjacent each of the microchannel first ends, and an opposite fluid outlet opening from the plurality of microchannels can be positioned adjacent each of the microchannel opposite ends such that a flow of heat transfer fluid passing into the plurality of microchannels flows along the full length of each of the plurality of microchannels outwardly from the fluid inlet opening. Related methods are disclosed.

1. A fluid heat exchanger for cooling an electronic device, the heat exchanger comprising:
a plurality of spaced-apart walls defining a corresponding plurality of microchannels having respective first ends and second ends; a plate positioned over the plurality of walls and closing off the plurality of microchannels, wherein the plate defines an elongate inlet aperture opening to the microchannels at a position between the respective first ends and second ends; a housing positioned over and spaced apart from the plate, wherein the housing has an inlet port and an outlet port, and the inlet port opens to an inlet header at a first position adjacent a proximal end of the elongate inlet aperture, and wherein the outlet port is spaced apart from the inlet port and opens from an outlet header at a second position spaced apart from and opposite the first position; and a seal extending between the housing and the plate and separating the inlet header from the outlet header, wherein a fluid flow through the inlet port into the inlet header thereafter passes through the elongate inlet aperture opening to the plurality of microchannels and is split generally into two subflows, wherein one of the subflows flows outwardly from the inlet aperture to the microchannel first ends and passes from the microchannel first ends into the outlet header, and from the outlet header through the outlet port.
