The invention discloses a serpentine tube microchannel heat exchanger. The serpentine tube microchannel heat exchanger comprises two flow gathering tubes and a plurality of flat tubes. Each flow gathering tube is provided with a plurality of circulating holes, and at least two circulating holes in each flow gathering tube are arranged in a staggered mode in the circumferential direction. The multiple flat tubes are in parallel connection with the position between the two flow gathering tubes, at least a part of each flat tube extends in a serpentine mode or extends around the flow gathering tubes, the two ends of each flat tube are connected with the circulating holes in the two flow gathering tubes correspondingly, the multiple flat tubes and the multiple circulating holes in each flow gathering tube are arranged in one-to-one correspondence mode. According to the serpentine tube microchannel heat exchanger, the length of a single refrigerant flow path can be shortened to reduce the side flow resistance and pressure drop of a refrigerant of the heat exchanger. A refrigeration system using the heat exchanger can improve the heat exchanging efficiency. In addition, the arrangement form of the flat tubes of the heat exchanger is various according to the different environmental conditions such as the mounting space size, and the application occasion of the serpentine tube microchannel heat exchanger can be enlarged.
