Abstract
The utility model relates to an air cooler pipe box with flow deflectors. Two flow deflectors are symmetrically arranged in the pipe box and are respectively inclined towards the two side edges of the pipe box from a main water pipe of the pipe box so as to lead the sections along the directions of the two sides in the pipe box to be gradually reduced. In the air cooler pipe box disclosed by the utility model, the water-side freezing of an air cooler in winter low-temperature weather can be effectively prevented. In the air cooler pipe box, the water-side speed at a collecting pipe outlet is increased, the dead area can be effectively avoided, the water-side convection heat exchange coefficient is improved, and the water-side heat resistance is reduced, so that the antifreezing capability of a system is improved.
Description
Technical field
The utility model relates to a kind of bobbin carriage that has flow deflector that is used for the power station indirect air cooling system, and this bobbin carriage can effectively improve the antifreeze ability of the bobbin carriage of winter severe cold period.
Technical background
The coal resources of China three northern areas of China are abundanter, but because water resources shortage, the effective water-saving device of indirect type air cooling system conduct is in this area's extensive use.Indirect air cooling system is made up of condenser and air cooling tower.Be furnished with Air-cooled Heat Exchanger in the air cooling tower.Water circulates in the pipe side of condenser and the pipe side of air cooler, and the exhaust steam of steam turbine cooling by water at low temperature in condenser realizes condensation, and the air cooler that heated water is recycled in the air cooling tower is cooled off by air.Water takes heat the air to from exhaust steam in steam turbine as intermediate medium.Air cooling tower is because the effect of free convection is aspirated into air cooling tower to the air of extraneous low temperature is discharged by cat head.The temperature of outside air is lower than 0 ℃ when moving in the winter time, and the air of recirculated water and low temperature carries out heat exchange.At air cooler water side outlet, just may be near or below the temperature that freezes through the temperature of the water of supercooling.
The shape at present traditional bobbin carriage cross section 1 is a not variable cross-section (as shown in Figure 1).Find by the analysis to the bobbin carriage flow field: because the outlet pipe intermediate arrangement, outermost water velocity is very low.Be " dead band " in the whole air cooling system herein, cause the tube wall water side coefficient of heat transfer to reduce because the flow velocity of water hangs down in this zone.When environment temperature is low, easily freeze herein.Freeze to spread and to stop up the outermost heat-transfer pipe, and then heat-transfer pipe will bursting by freezing.
The utility model content
The purpose of this utility model is to provide a kind of air cooler bobbin carriage that has flow deflector that is used for the power station indirect air cooling system, to overcome the defective that exists in the known technology.
For achieving the above object, the air cooler bobbin carriage that has flow deflector that the utility model provides, be in bobbin carriage, to be symmetrically arranged with two flow deflectors, these two flow deflectors from the dual-side of the oblique bobbin carriage in the water-main place of bobbin carriage (being respectively from the dual-side and the finned tube junction of the oblique bobbin carriage in the water-main place of bobbin carriage preferably with two flow deflectors), dwindle two side direction cross sections in the bobbin carriage respectively gradually.
The described air cooler bobbin carriage that has flow deflector, wherein flow deflector is shaped as plane or curved surface.
The air cooler bobbin carriage that has flow deflector that the utility model provides, two flow deflectors that symmetry adds can improve the interior both sides water velocity away from central authorities of bobbin carriage, and then improve the coefficient of heat transfer and avoid freezing.
Description of drawings
Fig. 1 is known air cooler channel structure.
Fig. 2 is an air cooler channel structure schematic diagram of the present utility model.
The specific embodiment
The air cooler bobbin carriage of power station of the present utility model indirect air cooling system is to weld two flow deflectors in known air cooler bobbin carriage symmetrically.See also Fig. 2, this figure has analysed and observe a side of air cooler bobbin carriage of the present utility model 1 inside.Because the utility model is to be welded with flow deflector 3 symmetrically in the inside of air cooler bobbin carriage 1, therefore the opposite side of not analysing and observe is identical with the side structure that Fig. 2 shows.The shape of flow deflector 3 can be plane or arbitrary surface.
Below be that example describes only with the one side, one end of flow deflector 3 is welded on the junction of water-main 2 and air cooler bobbin carriage 1, the other end of this flow deflector 3 obliquely is welded on the side and finned tube 4 junctions of air cooler bobbin carriage 1, and the inner space of air cooler bobbin carriage 1 is diminished gradually by the cross section of middle water-main to air cooler bobbin carriage both sides.Because the utility model makes the flow section of fluid diminish gradually to two lateral sections from air cooler bobbin carriage central authorities (water-main), therefore can improve the interior both sides water velocity of bobbin carriage, and then improve the coefficient of heat transfer and avoid freezing away from water-main.
Claims (3)
1. an air cooler bobbin carriage that has flow deflector is characterized in that, is symmetrically arranged with two flow deflectors in the bobbin carriage, and these two flow deflectors from the dual-side of the oblique bobbin carriage in the water-main place of bobbin carriage, dwindle two side direction cross sections in the bobbin carriage respectively gradually.
2. according to the described air cooler bobbin carriage that has flow deflector of claim 1, it is characterized in that two flow deflectors are respectively from the dual-side and the finned tube junction of the oblique bobbin carriage in the water-main place of bobbin carriage.
