Technical field:

The utility model relates to air-conditioning technical field, refers in particular to a kind of superposition type multilevel evaporation core body.

Background technology:

At present, conventional air-conditioning evaporative cooling heat exchanging core has two big classes, a kind of is direct evaporative cooling core body, water directly contacts with needing the cooling air, latent heat by the water evaporation process reduces air themperature, in this process, and the constant in energy of air, just the air with dry high temperature becomes nice and cool moistening air, and the cooling efficient of such heat exchanger is 70-90% air inlet wet-bulb temperature.Another kind is a single-stage indirect evaporation heat exchange core body, it mainly constitutes stacked staggered vertical channel and the horizontal channel that does not communicate with each other by aluminium foil flaggy and supporter, the horizontal channel that blower fan is introduced core body with outdoor direct wind, by the aluminium foil flaggy heat is passed to core body vertical channel flowing spray water, wet coolings such as direct wind self realization, between give a dinner for a visitor from afar air-introduced machine will between give a dinner for a visitor from afar and from bottom to top introduce vertical channel, with flow reversal, and contact with water and to carry out heat exchange, moisture evaporates from the heat-transfer surface top layer, after evaporating the heat that has absorbed in heat-transfer surface and the direct wind of heat-transfer surface opposite side, discharge outdoor with giving a dinner for a visitor from afar between the humidity rising by air-introduced machine.The weak point of above-mentioned two kinds of evaporative cooling core bodys:, increased the water capacity of air though directly the evaporative cooling core body can make the temperature of air reduce; The indirect evaporation core body can obtain lower air dry-bulb temperature under the condition that does not increase the air water capacity, but the limiting value of its leaving air temp such as is at the wet-bulb temperature that reaches local air after the wet cooling.Air service index such as the leaving air temp that provides of two kinds of evaporative cooling core bodys, humidity has certain limitation thus, and the scope of application is restricted.

The utility model content:

At the deficiencies in the prior art, the purpose of this utility model is to provide a kind of superposition type multilevel evaporation core body, blander new wind not only can be provided, and little power consumption, the efficiency ratio height, can make leaving air temp under the condition that waits wet cooling, can be lower than the wet-bulb temperature of local air, even with the dew-point temperature of leaving air temp near local air.

For achieving the above object, the utility model adopts following technical scheme: a kind of superposition type multilevel evaporation core body, at least comprise an indirect evaporation unit and a base, the indirect evaporation unit comprises at least three heat-transfer films and at least two heat conductive wall, heat conductive wall is a waveform, its compound mode is heat-transfer film successively, heat conductive wall, heat-transfer film, heat conductive wall, heat-transfer film, heat-transfer film and heat conductive wall are bonding by glue, the core body bottom is a scarf, offer groove on the scarf, a heat conductive wall and two heat-transfer films constitute dry passage, and another piece heat conductive wall and two heat-transfer films constitute wet channel, and dry passage and wet channel are square crossing and distribute.

Described wet channel, dry passage are respectively clearance channel.

Described wet channel is a vertical direction.

Described dry passage is a horizontal direction.

The heat conductive wall that described wet channel supports adopts special hygroscopic fibre material, and the heat conductive wall that dry passage supports adopts non-absorbent material.
