1. A multi-channel flat-tube serpentine heat exchanger (1), including:

  • a flat pipe (10) configured to have a plurality of bending sections (11) and a plurality of connecting sections (12) each connecting adjacent two bending sections (11), an interior of the flat pipe (10) being filled with a working fluid (W), the flat pipe (10) being provided with a plurality of channels (13) separated from each other for allowing the working fluid (W) to flow through;

    a fin set (20) connected between the connecting sections (12) to increase heat-exchange area of the flat pipe (10); and

    a divider assembly (30) connected to the flat pipe (10) to divide the flat pipe (10) into a heat-absorbing region (S1) located in a lower portion of the flat pipe (10) and a heat-releasing region (S2) located in an upper portion of the flat pipe (10), the divider assembly (30) being disposed between the heat-absorbing region (S1) and the heat-releasing region (S2);

    wherein a portion of the working fluid (W) in the heat-absorbing region (51) absorbs heat to evaporate, the evaporated working fluid (W) flows into the heat-releasing region (S2) along the channels (13), the evaporated working fluid (W) condenses in the heat-releasing region (S2) to flow back to the heat-absorbing region (51) along the channels (13) by means of gravity.
