A water chiller-heater unit with a tube-and-plate type compound heat exchanging evaporative condenser comprises a compressor (5), an evaporative condenser (4), a throttling device (6), and an evaporator (7). The evaporative condenser (4) comprises a fan (41), a water pump (42), a water distributor (43), and a collecting basin (44). The evaporative condenser (4) further comprises a tube-and-plate type compound heat exchanger. The tube-and-plate type compound heat exchanger (45) is formed by connecting multiple tube-and-plate type compound heat exchange sheets between an inlet header and an outlet header. The tube-and-plate type compound heat exchange sheets comprise a heat transfer plate (2) and a coil pipe (1) formed by a shaped heat exchange pipe. The heat transfer plate (2) is provided with an accommodation groove (21). The shape of the accommodation groove (21) matches the shape of the coil pipe (1). The coil pipe (1) is placed in the accommodation groove (21). The gap between the coil pipe (1) and the accommodation groove (21) is filled with a thermally conductive bonding layer (3). The thermally conductive bonding layer (3) ensures full contact between the heat transfer plate (2) and the coil pipe (1), thereby enlarging the effective heat exchange area. The heat transfer plate (2) can also drain cooling water to form a continuous water flow surface, thereby increasing the evaporation surface area of the cooling water, improving heat exchange efficiency and also reducing condenser size. |
