Microchannel heat exchanger for appliance condenser

A heat exchanger, comprising:

• a microchannel tube having a plurality of straight sections interconnected by a plurality of bent sections;
• a plurality of accordion-style fins located between adjacent straight sections of the microchannel tube;
• and
• a plurality of brackets having a plurality of slots formed therein that are each configured for receipt of a respective straight section of the microchannel tube,
• wherein the microchannel tube includes an upper major surface and a lower major surface that each include plurality of projections that extend longitudinally at least along each of the plurality of straight sections;
• the accordion-style fins located between adjacent straight sections of microchannel tubes include a plurality of recesses that are configured to mate with the plurality of projections such that when the recesses are mated with the projections, the accordion-style fins are restricted from moving laterally relative to the adjacent straight sections of the microchannel tube;
• and
• wherein the accordion-style fins are compressed by the adjacent straight sections of the microchannel tube a distance that lies in the range of 0.003 inches to 0.015 inches.
