Compared with a water cooling system, the water cooling system has the advantages of low investment, water saving, environmental pollution reduction, convenient operation, long service life and the like. However, in northwest areas with high dry bulb temperature and dry environment in summer and in arid and semi-arid areas, the temperature difference between the inlet and the outlet of the cooled medium is large, and the requirement on the outlet temperature is low, the dry air cooler has the phenomenon that the heat exchange effect is poor, and even the design working condition cannot be met.

SUMMERY OF THE UTILITY MODEL

In order to avoid the phenomenon that a dry type air cooler has poor heat exchange effect in summer and even cannot meet the design working condition, the utility model provides the humidifying water-saving type condenser.

The technical scheme adopted by the utility model is as follows:

the utility model provides a humidification water-saving condenser, includes the box, and the bottom half is provided with the catch basin, and the box top is provided with the draught fan, and box central authorities are the air-out space, and air-out space both sides are provided with the heat exchange assembly, and the heat exchange assembly outside is provided with the air precooling subassembly, and air precooling subassembly top is provided with the water inlet, and air precooling subassembly below and catch basin intercommunication are provided with the water pump in the catch basin, and the water pump passes through the pipe connection with the water inlet.

In a specific case, the air pre-cooling assembly is filled with a honeycomb structure for air and water to pass through.

Preferably, the heat exchange assembly is of a tube-fin structure, and a plurality of rows of series-connected heat exchange tubes are horizontally arranged in the heat exchange assembly at intervals from top to bottom.

The working principle of the humidifying water-saving condenser of the utility model is as follows: the dry unsaturated air with higher temperature is introduced, and is pre-cooled and humidified to be low-temperature humid air in a nearly saturated state, so that the heat exchange capability of the air is improved. Then the low-temperature humid air passes through the surface of the heat exchange assembly and exchanges heat with the high-temperature medium in the pipe to form hot humid air, and the hot humid air is discharged out of the equipment under the action of the draught fan.

The modularized and unique heat exchange structure enhances the condensation of media in the pipe while improving the heat exchange capability of air in a mode of combining heat transfer and mass transfer, thereby achieving the effects of saving energy and water and enhancing heat transfer.

Compared with the prior art, the utility model has the beneficial effects that: the problems that the dry air cooler has poor heat exchange effect and even cannot meet the design working condition when the temperature of the environment is high in summer, the temperature difference of the cooled medium inlet and outlet is large and the requirement on the outlet temperature is low in dry areas such as arid areas and semi-arid areas are solved. Compared with a water-cooled cooler, the water introduced in the utility model only humidifies and cools air, and does not exchange heat with a heat medium, thereby saving water. Meanwhile, the modularized structure is simple to install, convenient to operate, low in investment cost, low in operation and maintenance cost, water-saving and electricity-saving, and is a good energy-saving product.
