<p>Disclosed is a cold water machine group of a filler coupling coil pipe evaporative type condenser (2), comprising a compressor (1), an evaporative type condenser (2), a throttling device (3) and an evaporator (4). The evaporative condenser (2) comprises a coil pipe heat exchanger, a draught fan (21), a water distributor (23) and a water collection pool (24). The coil pipe heat exchanger is formed by a plurality of heat exchange pipe pieces which are connected through an inlet collecting pipe (28) and an outlet collecting pipe (29), and each heat exchange pipe piece comprises a coil pipe (26) and a filler (27). At least one filler layer (27) used for guiding spraying cooling water to flow from an upper layer exchange pipe (261) to a lower layer exchange pipe (261) is arranged in the coil pipe (26). The coil pipe (26) is longitudinally arranged, that is, cooling air blown by the draught fan (21) flows along the approximate length direction of a straight pipe segment of the coil pipe (26). The present invention can reduce the cooling water temperature in the cooling coil pipe (26), and improve the water distribution coverage rate of the cooling water in the cooling coil pipe (26), and has the advantage of high heat transfer efficiency.</p> |
