Method and system for cooling a fluid with a microchannel evaporator

A heat exchanger system comprising:

• a fluid tank comprising a first-fluid inlet to permit a first fluid to enter the fluid tank and a first-fluid outlet to permit the first fluid to exit the fluid tank;
• and
• a microchannel evaporator disposed within the fluid tank, the microchannel evaporator comprising:
• a plurality of microchannels, each microchannel of the plurality of microchannels comprising a first end and a second end;
• a first end-tank coupled to said each first end of the plurality of microchannels;
• a second end-tank coupled to said each second end of the plurality of microchannels;
• an inlet coupled to either the first end-tank or the second end-tank and configured to receive the first fluid into the microchannel evaporator;
• an outlet coupled to either the first end-tank or the second end-tank and configured to expel the first fluid from the microchannel evaporator;
• wherein each microchannel has a length that extends between the first and second end-tanks, the length being made up of a central portion, wherein the central portion comprises the length between a first end portion closest to the first end tank and a second end portion closest to the second end tank;
• a plurality of fins disposed along only the central portion between at least two microchannels of the plurality of microchannels;
• and
• an agitator disposed in proximity to the microchannel evaporator and configured to add turbulence to a flow of the first fluid.

A microchannel evaporator system comprising:

• a microchannel evaporator comprising:
• a plurality of microchannels, each microchannel comprising a first end and a second end;
• a first end-tank coupled to each of the first ends of the plurality of microchannels;
• a second end-tank coupled to each of the second ends of the plurality of microchannels;
• a second-fluid inlet coupled to either the first end-tank or the second end-tank and adapted for receiving a second fluid into the microchannel evaporator;
• a second-fluid outlet coupled to either the first end-tank or the second end-tank and adapted for expelling the second fluid from the microchannel evaporator;
• wherein each microchannel comprises a bend along a length thereof;
• and
• an agitator disposed in proximity to the microchannel evaporator and configured to add turbulence to a flow of a first fluid.
