Description
Technical field
The present invention relates to air conditioner refrigerating technical field, especially relate to a kind of upper air inlet type evaporating type condensing device.
Background technology
Along with social development, the contradiction that the raising of air conditioning energy consumption proportion in life, production total energy and energy shortage form highlights day by day.Therefore, the evaporative condenser technology with economize on electricity, environmental protection, the series of advantages such as efficient is widelyd popularize, become an important development direction of current air-conditioning technical field.
Evaporative condenser is as the High Efficiency Thermal switching equipment of a kind of energy-conservation, water saving, compact conformation, and it is by air-conditioning technical field extensive use.When concrete use, the usefulness quality of this evaporative condenser is directly connected to the cooling-down effect of evaporation condensing plant, and for evaporative condenser, version is the principal element that determines its exchange capability of heat.
At present, cooling-air is many enters from side or the below of evaporative condenser.In the time adopting cooling-air side mode of entrance, if shower water flow is excessive, owing to existing certain shearing force on air and moisture film interface, moisture film is in the process flowing downward, there will be liquid fluctuating, excessive once fluctuate, can cause the local fracture of moisture film, thereby worsen heat and mass effect.In the time adopting cooling-air below mode of entrance, if when wind speed is too large, there will be owing to shortening time of contact between air and condenser and reduce its effect, even there is air-supply water phenomenon.
Meanwhile, present heat exchange coil mainly adopts common pipe or elliptical tube.Although the more common pipe heat transfer efficiency of elliptical tube increases, and still exists the inhomogeneous defect of water distribution, moisture film is easily piled up in pipe bottom, causes moisture film blocked up, increases heat transfer resistance, reduces heat exchange efficiency.
Summary of the invention
The object of this invention is to provide a kind of upper air inlet type evaporating type condensing device, it has the advantages that heat exchange efficiency is higher.
The technical solution adopted in the present invention is: upper air inlet type evaporating type condensing device, comprise Tube Sheet of Heat Exchanger group, cooling-air source and blower fan, and be distributed with heat exchanger tube in this Tube Sheet of Heat Exchanger group, described Tube Sheet of Heat Exchanger group is positioned at below, cooling-air source, and this Tube Sheet of Heat Exchanger group top is provided with spray distributing pipe, this spray distributing pipe is provided with water jet, the water of this water jet ejection this Tube Sheet of Heat Exchanger group of flowing through downwards.
The water jet of described spray distributing pipe is: the bottom of this spray distributing pipe is provided with nozzle.
The water jet of described spray distributing pipe is: the side of this spray distributing pipe is provided with duckbilled pipe, and the front of this duckbilled pipe is provided with water fender.
The heat exchanger tube of described Tube Sheet of Heat Exchanger group is the pipe of φ 9.52 × 0.35mm.
The heat exchanger tube of described Tube Sheet of Heat Exchanger group is with 17.88 × 17.88 × 20.37mm isosceles triangle pattern stringing.
The advantage that compared to the prior art the present invention had is: heat exchange efficiency is higher.Upper air inlet type evaporating type condensing device of the present invention only need use less water spray, under the effect of water surface tension, because cooling-air direction is consistent with moisture film direction, and under the thrust of air, can form uniform and stable complete moisture film at heat exchange tube wall surface, increase effective acting time and the area of air and moisture film, energy heat and mass transfer enhancement process, rises the condensation efficiency of evaporative condenser.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the schematic perspective view of embodiments of the invention 1;

Fig. 3 is the left view of Tube Sheet of Heat Exchanger group of the present invention.
In figure: 1-Tube Sheet of Heat Exchanger group, 11-heat exchanger tube; 2-nozzle; 3-sprays distributing pipe; 4-blower fan; 5-duckbilled pipe; 6-water fender; 100-cooling-air source.
The specific embodiment
Embodiment 1, as shown in Figure 1: upper air inlet type evaporating type condensing device, comprises blower fan 4, and be positioned at the Tube Sheet of Heat Exchanger group 1 of 100 belows, cooling-air source.The cooling air that, this cooling-air source 100 blows out this Tube Sheet of Heat Exchanger group 1 of flowing through from top to bottom.Certainly, in this Tube Sheet of Heat Exchanger group 1, be distributed with some heat exchanger tubes 11.Meanwhile, this Tube Sheet of Heat Exchanger group 1 top is provided with spray distributing pipe 3, and this spray distributing pipe 3 is provided with water jet, the water of this water jet ejection this Tube Sheet of Heat Exchanger group 1 of flowing through downwards.Like this, the water direction of water jet ejection and cooling-air are in the same way, spray is to the surface of the heat exchanger tube 11 of Tube Sheet of Heat Exchanger group 1, make heat exchanger tube 11 outer surfaces form the thin water film of continuous uniform, this thin water film and cooling-air carry out the wet exchange of heat, and blower fan 4 is extracted saturated moist air out and entered atmosphere from top fan outlet from tube bank.
In the present embodiment, the water jet of this spray distributing pipe 3 is: the bottom of this spray distributing pipe 3 is provided with nozzle 2.The water spray of such nozzle 2 is directly sprayed onto heat exchanger tube 11 surfaces, have advantages of simple in structure, adaptable to hydraulic pressure, spray area is large.
As shown in Figure 3: the heat exchanger tube 11 of this Tube Sheet of Heat Exchanger group 1 adopts the pipe of φ 9.52 × 0.35mm, that is, external diameter is the pipe that φ 9.52mm, tube wall are 0.35mm.The heat exchanger tube 11 of this Tube Sheet of Heat Exchanger group 1 is with 17.88 × 17.88 × 20.37mm isosceles triangle pattern stringing.That is, with one group of every two behavior, in every group the line of centres of 3 adjacent heat exchanger tubes 11 be waist long for 17.88mm, base be 20.37mm isosceles triangle.Such heat exchanger tube 11 and distribution form thereof make every heat exchanger tube 11 all can accept largely the spray of top water spray.
