Abstract
The utility model discloses a kind of finned cooling tower air duct, comprise cylindrical tube, the outer wall of described cylindrical tube has been evenly arranged multiple thermal-arrest fin, in described cylindrical tube, has been filled with thermal-arrest net.This finned cooling tower air duct can reduce damp-heat air flowing resistance and air-teturning mixed phenomenon in hot environment, can accelerate damp steam condensation, reduce evaporated water and eliminate or reduce cooling tower outlet water smoke in low temperature environment.
Description
Technical field
The utility model relates generally to field of heating ventilation air conditioning, particularly relates to a kind of finned cooling tower air duct.
Background technology
Cooling tower is the important component part of heating ventilation air-conditioning system, its effect is that the recirculated water carrying waste heat is carried out heat exchange at Ta Nei and air, the delivered heat of water is spilt into air to air, lowers the temperature to recirculated water.The quality of cooling tower runnability directly affects the effect of air-conditioning system cooling and warming.
Damp-heat air can be produced after cooling tower Inner eycle water and air carry out exchange heat export from cooling tower and discharge, if the damp-heat air in the exit of cooling tower can not obtain effective lifting, affect the diffusion of damp hot discharge air, cause damp and hot air-flow back mixing, reduce the performance of cooling tower.So be back in cooling tower to reduce damp-heat air, common way installs air duct in cooling tower exit, its Main Function creates good air force condition, reduces flowing resistance, and the damp-heat air of discharging cooling tower is sent to the backflow of high-altitude minimizing damp-heat air.
After although air duct installed by cooling tower, can reduce damp-heat air backflow, it can not solve two subject matters: after 1, air duct installed by cooling tower, adds the resistance of damp-heat air flowing, thus adds fan operation cost; 2, after air duct installed by cooling tower, can not reduce environment temperature lower time the damp-heat air white mist that formed produce.
Utility model content
The technical problems to be solved in the utility model overcomes the deficiencies in the prior art, there is provided one can reduce damp-heat air flowing resistance and air-teturning mixed phenomenon in hot environment, damp steam condensation can be accelerated in low temperature environment, reduce evaporated water and eliminate or reduce the finned cooling tower air duct that cooling tower exports water smoke.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of finned cooling tower air duct, comprises cylindrical tube, the outer wall of described cylindrical tube has been evenly arranged multiple thermal-arrest fin, has been filled with thermal-arrest net in described cylindrical tube.
Further improvement as technique scheme:
Described thermal-arrest fin is the rectangle plain fin axially arranged along cylindrical tube, and multiple thermal-arrest fin is uniformly distributed along cylindrical tube circumference.
Described thermal-arrest fin is the annular flat straight fins arranged along cylindrical tube circumference, and multiple thermal-arrest fin is axially uniformly distributed along cylindrical tube.
Described thermal-arrest net is arranged along cylindrical tube radial section.
Described thermal-arrest net is provided with multilayer, and multilayer thermal-arrest net is axially uniformly distributed along cylindrical tube.
Described cylindrical tube is metal cylinder, and described thermal-arrest fin is metal fin, and described thermal-arrest net is wire netting.
Compared with prior art, the utility model has the advantage of:
Finned cooling tower air duct of the present utility model is similar to a heat exchanger, in the summer that temperature is higher, solar irradiation is mapped on the thermal-arrest fin of finned cooling tower air duct, thermal-arrest fin and cylindrical tube temperature are raised, then heat is passed to Hot wet air heating by thermal-arrest net in air duct, Hot wet air heating temperature raised and forms larger buoyancy lift, discharging for damp-heat air and create good air force condition, decrease flowing resistance and the air-teturning mixed phenomenon of damp-heat air; In the winter that temperature is lower, damp-heat air in cylindrical tube passes to surrounding environment cold air by cylindrical tube and thermal-arrest fin heat, accelerate damp steam in damp-heat air condense in cylindrical tube and come back to cooling tower, reduce evaporated water and economize on water, cooling tower outlet water smoke can be eliminated or reduce simultaneously, be conducive to environmental protection.

Detailed description of the invention
Below with reference to Figure of description and specific embodiment, the utility model is described in further details.
Fig. 1 to Fig. 3 shows the first finned cooling tower air duct embodiment of the present utility model, and this cooling tower air duct comprises cylindrical tube 1, the outer wall of cylindrical tube 1 has been evenly arranged multiple thermal-arrest fin 2, has been filled with thermal-arrest net 3 in cylindrical tube 1.Finned cooling tower air duct of the present utility model is similar to a heat exchanger, be arranged on cooling tower 4 top, in the summer that temperature is higher, solar irradiation is mapped on the thermal-arrest fin 2 of finned cooling tower air duct, thermal-arrest fin 2 and cylindrical tube 1 temperature are raised, then heat is passed to Hot wet air heating by thermal-arrest net 3 in air duct, Hot wet air heating temperature is raised and forms larger buoyancy lift, discharge for damp-heat air and create good air force condition, decrease flowing resistance and the air-teturning mixed phenomenon of damp-heat air; In the winter that temperature is lower, damp-heat air in cylindrical tube 1 passes to surrounding environment cold air by cylindrical tube 1 and thermal-arrest fin 2 heat, accelerate damp steam in damp-heat air condense in cylindrical tube 1 and come back to cooling tower 4, reduce evaporated water and economize on water, can eliminate or reduce cooling tower 4 exports water smoke simultaneously, is conducive to environmental protection.
In the present embodiment, thermal-arrest fin 2 is the rectangle plain fin axially arranged along cylindrical tube 1, multiple thermal-arrest fin 2 is uniformly distributed along cylindrical tube 1 circumference, thermal-arrest net 3 is arranged along cylindrical tube 1 radial section, and thermal-arrest net 3 is provided with multilayer, multilayer thermal-arrest net 3 is axially uniformly distributed along cylindrical tube 1.Cylindrical tube 1 is metal cylinder, and thermal-arrest fin 2 is metal fin, and thermal-arrest net 3 is wire netting.The thermal-arrest fin 2 of the present embodiment is provided with 8 altogether, and thermal-arrest net 3 is provided with 10 layers altogether.
