A kind of structure of surface evaporation air cooler bobbin carriage, including tube sheet two, the side of tube sheet two is welded with heat exchanger tube, opposite side welds with the planar side of semicircle bobbin carriage, semicircle bobbin carriage arc end face connects medium inlet pipe two or media outlet pipe two, and this utility model eliminates the flange on bobbin carriage than square bobbin carriage, adds intensity and the resistance to pressure of bobbin carriage than circular bobbin carriage, on the other hand not only increase the fastness that exchanger tubes and tubesheets connects, the maintenance of tube head can be facilitated again.
Description
Technical field
This utility model relates to the structure of a kind of surface evaporation air cooler bobbin carriage.
Background technology
The bobbin carriage of conventional surface evaporating air cooler uses square bobbin carriage or circular bobbin carriage, such as Fig. 1, rectangular tube
Case 1 is made up of tube sheet 1, plug plate 12, upper lower roof plate 13 and left and right end plate etc., and entrance sets into
Mouth flange 14, outlet arranges outlet(discharge) flange 15, and this structure takes up room greatly, and waste material, cost
Higher.Such as Fig. 2, circular bobbin carriage 2 is made up of with both sides end cap 21 round steel pipe, and entrance arranges medium inlet
Pipe 1, outlet arranges media outlet pipe 1, and this structure exchange heat pipe 41 cannot be carried out expanded joint, if
Heat exchanger tube 41 has leakage to be difficult to overhaul.The tube bank of both structures simultaneously easily produces under fluid impact shakes
Moving and cause connection place fatigue rupture, this is accomplished by a kind of not only material saving performance but also good New pipe box structure.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of surface evaporation
The structure of air cooler bobbin carriage, it is possible to increase air cooler bobbin carriage fastening and seal degree, efficiently solves air cooler
The problem of bobbin carriage, extends service life of equipment.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of structure of surface evaporation air cooler bobbin carriage, including tube sheet 2 33, the side of tube sheet 2 33 with change
Heat pipe 41 welds, and opposite side welds with the planar side of semicircle bobbin carriage 3, and semicircle bobbin carriage 3 arc end face is even
Connect medium inlet pipe 2 31 or media outlet pipe 2 32.
Described tube sheet 2 33 seals expanded joint with heat exchanger tube 41.
The two ends of described semicircle bobbin carriage 3 are welded with semicircle end cap 34.
Compared with prior art, this utility model eliminates the flange on bobbin carriage than square bobbin carriage, compares round tube
Case adds intensity and the resistance to pressure of bobbin carriage, on the other hand not only increases the firm of exchanger tubes and tubesheets connection
Property, the maintenance of tube head can be facilitated again.
Accompanying drawing explanation
Fig. 1 is rectangular tube box structure schematic diagram.
Fig. 2 is round tube box structure schematic diagram.
Fig. 3 is this utility model structural representation.
Detailed description of the invention
Embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings with embodiment.
As it is shown on figure 3, the structure of a kind of surface evaporation air cooler bobbin carriage, at traditional surface evaporative air cooling
On the basis of device bobbin carriage, use tube sheet and the mode that semicircle bobbin carriage is combined, specifically include tube sheet 2 33, pipe
The side of plate 2 33 is welded with heat exchanger tube 41, and after welding, tube sheet 2 33 also seals expanded joint with heat exchanger tube 41,
Heat exchanger tube 41 is connected more firm with tube sheet 2 33, the most firm heat exchanger tube 41 and the tube sheet two
The crevice corrosion of 33, exchanges heat pipe 41 support, positioning action.The opposite side of tube sheet 2 33 is with semicircle
The planar side welding of bobbin carriage 3, if at arrival end, then semicircle bobbin carriage 3 arc end face connects medium inlet pipe two
31, if at the port of export, then semicircle bobbin carriage 3 arc end face connects media outlet pipe 2 32.Semicircle bobbin carriage 3
Two ends be welded with semicircle end cap 34, forms the channel structure of one closing.
It implements process:
The pore of heat exchanger tube 41 is held successfully by tube sheet 2 33, heat exchanger tube 41 is pressed the weldering of the comb regularity of distribution
It is connected on tube sheet 2 33, then tube expander is inserted pipe head, make pipe head generation plastic deformation, until complete
Entirely it is fitted on pore inwall, and makes to deform around hole wall, and tube sheet 2 33 remains at elastic change
Shape state, the caliber after expansion can not reduce, and hole wall then wants elastic return to make aperture diminish (recovery),
Thus make heat exchanger tube 41 and tube sheet 2 33 link together tightly, utilize pipe end and tube sheet 2 33
Deformation between the groove of hole reaches fastening and seals, after tube sheet 2 33 and heat exchanger tube 41 connect, then will be partly
Circular bobbin carriage 3 is welded on tube sheet 2 33 with semicircle end cap 34, can reach saving material and convenient maintenance
Purpose, the fatigue rupture of heat exchanger tube 41 and tube sheet 2 33 junction can be reduced simultaneously.
Principle of the present utility model:
The basis more optimized based on energy-conservation, technology, at the scheme base of traditional remover for surface evaporation type air cooling bobbin carriage
On plinth, using the mode that square tube sheet is combined with semicircle bobbin carriage, U-shaped coil pipe, the principle of this structure is
The stronger resistance to pressure of semicircle bobbin carriage, and the stronger anti-stress corrosiveness that tube sheet is connected with heat exchanger tube, pass through tube sheet
Welding with heat exchanger tube, then heat exchanger tube carries out with tube sheet sealing expanded joint again so that exchanger tubes and tubesheets connects more
Add firmly, effectively solve the crevice corrosion of exchanger tubes and tubesheets, decrease the stress corrosion of tube head,
Exchange heat pipe play supports, positioning action, opposite side is welded to connect with semicircle bobbin carriage, semicircle bobbin carriage opposite side and
Pipeline connects, and bobbin carriage end cap is welded on semicircle bobbin carriage both sides, forms a semicircle bobbin carriage closed (such as figure
3), the most square bobbin carriage compares the flange eliminating on bobbin carriage, and opposing circular bobbin carriage compares and adds pipe
The intensity of case and resistance to pressure, on the other hand not only increase the fastness that exchanger tubes and tubesheets connects, the most permissible
Facilitate the maintenance of tube head.
