A high-efficient heat exchange tube piece for a filler coupling coil evaporative condenser comprises a coil (1) formed of heat exchange tubes coiled into an S shape. The coil (1) is provided with at least one layer of filler (2) for guiding spraying cooling water to flow from an upper layer heat exchange tube to a lower layer heat exchange tube. The filler (2) is arranged between adjacent heat exchange tubes (11), and connects the heat exchange tubes (11) to form a continuous water flow surface. The heat exchange tube is capable of lowering the temperature of cooling water in a cooling coil, and improving water distribution coverage of cooling water sprayed from the cooling coil and the heat exchange efficiency.
