Abstract

The invention discloses an efficient direct contact type water-air heat exchanging device. The efficient direct contact type water-air heat exchanging device comprises a water pipe, a circulating water pump, a water distributor, non-woven fabric composite filler, a draught fan, an air-inlet grille, a water collecting disk and an air-outlet grille. The water pipe communicates with the circulating water pump and the water distributor. The circulating water pump conveys high-temperature water to the water distributor through the water pipe. The water distributor evenly sprays the high-temperature water to the surface of the non-woven fabric composite filler. The non-woven fabric composite filler is of a multi-layer composite structure, each layer of the non-woven fabric composite filler is provided with a plurality of drain holes, water flows from top to bottom and conducts direct contact type heat exchange with air blown by the draught fan from the air-inlet grille, high-temperature and high-humidity air flows out through the air-outlet grille, and cooled water flows into the water collecting disk to be circularly used later. According to the efficient direct contact type water-air heat exchanging device, the effect of intensifying heat exchanging is achieved by prolonging the contact time of air and water and increasing the contact area of air and water.

Description

technical field [0001] The invention relates to a high-efficiency direct contact water-air heat exchange device, which belongs to the field of heat exchange devices, in particular to the field of direct contact water-air heat exchange devices. Background technique [0002] The working principle of the direct contact water-air heat exchange device is that the flowing air is in contact with the flowing water to exchange heat. On the one hand, the air and water directly convect heat transfer. On the other hand, due to the water vapor pressure difference between the water surface and the air, Under the action of pressure, part of the water evaporates to take away the latent heat of evaporation, thereby achieving the effect of lowering the water temperature. For example, the open cooling tower in the air conditioning system is a direct contact water-air heat exchange device. The cooling water carrying the condensation heat is in direct contact with the air inside the tower to exc...
