Abstract
A heat exchanging core for a micro-channel heat exchanger includes at least one heat conducting plate, which has at least one channel formed between a first side and a second side of the heat conducting plate. The at least one channel has a channel length to hydraulic diameter ratio of less than 100, wherein the channel length is defined as a distance between the first and second sides of the heat conducting plate. A micro-channel heat exchanger includes a housing defining a cavity therein, the housing including an inlet and an outlet coupled to the cavity, and a heat exchanging core positioned within the cavity between the liquid inlet and the liquid outlet. The present invention provides, among other features, improved heat transfer, reduced pressure drops, and reduced jitter. The present invention can be implemented for laminar flow and/or turbulent flow environments.
