Fig. 2 is a partial exploded view of the present utility model.As can see from Figure 2, on blower fan 2, be provided with a blower hood 23.Blower hood 23 is provided with a water filling port 231, and the water in the tank injects by this water filling port.When Cooling air electrical fan moved, water filling port was covered by a sealing plate, so that the inside of Cooling air electrical fan and the external world carry out is heat insulation.The top of air intake heat-exchanging component 4 is provided with a heat-exchanging component outer cover 8, heat-exchanging component outer cover 8 is being provided with the current distributing trough 81 of opening with each corresponding position of heat exchange grid of air intake heat-exchanging component 4, cooling water can fall by current distributing trough 81, soaks the heat exchange grid.Heat-exchanging component outer cover 8 is connected with tank 2 with blower hood 23, blower fan 2, air intake heat-exchanging component 4 and air-out heat-exchanging component 7 can be covered, make it with outside have good heat insulation.Can also see that from Fig. 3 formed a water stream channel 232 in blower hood 23, this passage communicates with heat-exchanging component outer cover 8.The water that from water filling port 231, injects and can flow into tank 1 by water stream channel 232 from the water that heat-exchanging component outer cover 8 overflows.As shown in Figure 2, air-out heat-exchanging component 7 is arranged in the tank 1, and is arranged on the below of air intake heat-exchanging component 4.The top of air-out heat-exchanging component 7 is provided with a cage 9 that itself and air intake heat-exchanging component 4 are separated, each corresponding position of heat exchange grid with air-out heat-exchanging component 7 on cage 9 is provided with open slot 91, the water that air intake heat-exchanging component 4 fails to evaporate can fall by open slot 91, soaks the heat exchange grid of air-out heat-exchanging component 7.When cage 9 is connected with tank 1, the both sides of described air-out heat-exchanging component 7 have been covered.Above described air outlet 62, be provided with the upper spacer 65 that air inlet 61 and air outlet 62 are separated, below described air outlet 62, be provided with the lower clapboard 66 that tank and air outlet are separated.Cage 6 cooperates with upper spacer 65, makes the air-flow of air intake passage and the air-flow of air-out passage isolate.Also be provided with a base 31 below tank 1, it is the part of housing, comprises upper and lower two-ply, separates with the supporting gusset between top plate and the lower plywood, thereby forms an air heat-insulation layer 311 (see figure 3)s.Base 31 can be further with the cooling water in the tank 1 with extraneous heat insulation, help to reduce the temperature of the water that is used to cool off evaporation.
Fig. 3 is a left surface cutaway view of the present utility model, describes the course of work of the present utility model below in conjunction with Fig. 3.In Cooling air electrical fan when operation,, cooling water is sent to current distributing trough 81 by water pump, falls by current distributing trough 81 again, soaks into equably in the space of each cooling grid of air intake heat-exchanging component 4, and unnecessary water will be got back to tank 1 by water stream channel 232.Temperature is environment temperature T
0Air-flow all enter heat-exchanging component 4 by air inlet 61, rely on heat exchange grid with big disengagement area, water is evaporated in a large number, absorbs heat simultaneously, makes the temperature of air-flow reduce to T
3And unevaporated water enters into the heat exchange grid of air-out heat-exchanging component 7 by the current distributing trough 91 of cage 9.After air-flow after the cooling compressed acceleration through blower fan 2, temperature rose to T
4The air velocity that is accelerated is very high, and this high velocity air brushes the surface of water storage in the tank 1, and water is evaporated in large area.And high velocity air makes that the water on the heat exchange grid that flows to air-out heat-exchanging component 7 also is evaporated during through air-out heat-exchanging component 7.Thereby this air-flow is further cooled, and temperature is reduced to T
5In the process that high velocity air is cooled off once more, build a zone lower above the water storage 18 in tank than environment temperature, be called the cold house.Regional c shown in Fig. 3 bend part.Under the effect of blower fan, the air-flow one-way flow in the cold house.Multilayer heat insulation by base plate and tank, water resistance every with the effect of high velocity air, the air-flow of ambient temperature is difficult to enter into the cold house.Because under identical damp condition, environment temperature and water temperature form a metastable temperature difference, environment temperature is low more, and then corresponding water temperature is also low more.Therefore the water temperature that is used to cool off can reduce further.Water temperature is low more, and heat exchange efficiency is high more, and cooling effect is also just more obvious.Water through further cooling is sent to air intake heat-exchanging component 4, T like this
0And T
3Temperature can be more preceding once lower.So formed the direct circulation of a cooling.Along with the raising of humidity in the raising (water on grid can be heated) of heat exchange efficiency and the cold house, (evaporation efficiency can reduce), the water temperature decrease speed decreases, and tends to balance rapidly.After the water temperature balance, the temperature of air outlet can be near the environment damp-warm syndrome, i.e. wet bulb thermometer green end temperature.Under 33 ℃ and 70% relative humidity condition, (in the area, Shanghai) after measured, the temperature of the utility model air outlet is than environment temperature T
0Low more than 5 ℃, thus the good cooling effect obtained.
The utility model compared with prior art has the following advantages: 1. the utility model has adopted two-stage water evaporation and heat-exchange assembly, and cooling-down effect is more obvious; 2. the utility model has been built a low temperature subenvironment (cold house), makes water temperature lower, thereby has further improved the heat exchange amount; By cold house's effect, can keep lower water temperature enduringly, and the air-cooler of prior art reduces water temperature by placing ice crystal or frozen water, but the duration is quite limited; 3. the utility model adopts the heat exchange grid as heat-exchanging component, has increased disengagement area, and heat exchange grid shape rule, makes airflow smooth, and flow velocity is fast, has accelerated evaporation of water, thereby has improved heat exchange efficiency; 4. the utility model air outlet temperature is even.The air-cooler of prior art is because structure relationship of products, and a part of air-flow does not directly enter into blower fan through wet curtain, and this part air-flow and the air-flow that enters into blower fan through wet curtain have formed bigger thermograde at air outlet.And suction air-flow of the present utility model all will just enter into blower fan through the air intake heat-exchanging component.
Though description of the present utility model combines certain embodiments, it should be understood by one skilled in the art that the utility model is not limited to embodiment described here, and can make amendment and change and do not deviate from spirit and scope of the present utility model.Should think that the description of specification is schematic and nonrestrictive.
