The cold water from the heater 40 is transferred to the pre-cooling cavity through the flow guide structure 122 to improve the pre-cooling effect.
在使用过程中，换热器40表面的冷凝水滴落在集水槽123中，并通过导流结构122引导至排水口124排出，冷凝水在沿着导流结构122流动时，将自身的冷量传递给接水盘12，接水盘12再将冷量传递至散热片30中，并通过散热片30将冷量传导至预冷腔20内，与此同时，外部的高温新风进通过新风入口111进入预冷腔20内，并吸收散热片30散发的冷量，使高温新风的温度降低，形成低温新风，低温新风从新风出口121进入管风机内部，实现预冷，从而有效利用冷凝水中的冷量，提高能源利用率，避免凝露现象的产生，同时也避免因引入新风而导致换热效率下降的问题。During use, the condensed water on the surface of the heat exchanger 40 drops into the water collection tank 123 and is guided to the drain port 124 by the flow guide structure 122 to be discharged. When the condensed water flows along the flow guide structure 122, its own cooling capacity Transfer to the water receiving tray 12, the water receiving tray 12 then transfers the cold energy to the heat sink 30, and conducts the cold energy to the pre-cooling chamber 20 through the heat sink 30, at the same time, the external high-temperature fresh air enters through the fresh air inlet 111 enters the pre-cooling chamber 20 and absorbs the cooling energy emitted by the cooling fins 30 to reduce the temperature of the high-temperature fresh air and form low-temperature fresh air. Cooling capacity, improve energy utilization, avoid condensation, and avoid the problem of heat exchange efficiency reduction due to the introduction of fresh air.
