The present invention relates to a multi-channel flat-tube serpentine heat exchanger and a heat exchange apparatus. The heat exchanger includes a flat pipe, a fin set and a divider assembly. The flat pipe has bending sections and connecting sections. The flat pipe is filled with a working fluid and has channels.
