Micro-channel heat exchangers transfer heat through multiple flat fluid-filled tubes containing small channels while air travels perpendicular to the fluid flow. Compared to current fin-tube heat exchangers, the air passing over the heat exchanger has a longer dwell time, increasing both the efficiency and the rate of heat transfer. This increase in heat exchanger effectiveness allows the micro-channel heat exchanger to be smaller and yet have the same performance as a regular heat exchanger, or to get improved performance in the same volume as a conventional heat exchanger. The smaller size of the exchanger reduces the refrigerant pressure drop, improving overall compressor performance.
