Between only across pass partition 3, play the role of that hot-fluid and cold flow is isolated, although this isolation method is simple and easy, hot-fluid and
It is easy to carry out heat conduction by pass partition 3 between cold flow, completely efficient insulation isolation cannot be reached, hot-fluid side has greatly
The heat of amount is dispersed into cold flow side by pass partition 3, so that the temperature of cold flow side is also higher, just reduces heat exchanger
Overall heat exchange effect.It is higher in some occasion heat exchanging effect requirements, do not allow a large amount of heat that heat exchange is being completed
It is conducted between cold and hot fluid, existing bobbin carriage cannot be met the requirements.
In view of this, it is necessary to U-tube heat exchanger bobbin carriage in the prior art be improved, to solve the above problems.
Utility model content
The purpose of this utility model is that disclosing a kind of U-tube heat exchanger bobbin carriage, divide journey in vacuum state using internal
Hot-fluid and cold flow, good heat-insulation effect is isolated in partition cabinet, avoids not yet carrying out the tube side medium of heat exchange and carry out
Heat transfer is carried out between the tube side medium of heat exchange, improves the heat transfer effect of heat exchanger.
To achieve the above object, the utility model provides a kind of U-tube heat exchanger bobbin carriage, including bobbin carriage, the bobbin carriage
Pass partition cabinet is equipped with equipped with inlet tube and outlet, in the bobbin carriage to separate bobbin carriage is in upper and lower part, it is described on
Portion is connected to inlet tube, and the lower part is connected to outlet, is in vacuum state in the pass partition cabinet.
In some embodiments, the pass partition cabinet is equipped with sealing screw thread, further includes being threadedly coupled with sealing
Sealing silk plug.
In some embodiments, further include the tube sheet for being located at channel nozzle end, it is logical that several are offered on the tube sheet
Hole.
It in some embodiments, further include the connecting plate of one end Yu pass partition welding box body.
In some embodiments, it is equipped with transverse opening among the tube sheet, the connecting plate other end extends into transverse direction
In opening.
In some embodiments, the connection plate surface is coated with water proof rubber layer.
Compared with prior art, the utility model has the beneficial effects that U-tube Tube Sheet of Heat Exchanger provided by the utility model
Case avoids using internal pass partition cabinet isolation hot-fluid and cold flow, good heat-insulation effect in vacuum state and not yet carries out heat
Measure exchange tube side medium with carried out carrying out heat transfer between the tube side medium that heat exchanges, improve heat exchanger
Heat transfer effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of U-tube heat exchanger bobbin carriage shown in the prior art；
Fig. 2 is the structural schematic diagram of U-tube heat exchanger bobbin carriage shown in the utility model；
Fig. 3 is the structural schematic diagram of tube sheet shown in Fig. 2.
Specific embodiment
The utility model is described in detail in each embodiment shown in reference to the accompanying drawing, but it should be stated that,
These embodiments are not limitation of the utility model, those of ordinary skill in the art according to these embodiments made by function
Energy, method or equivalent transformation or substitution in structure, belong within the protection scope of the utility model.
A kind of U-tube heat exchanger bobbin carriage as shown in Figures 2 and 3, including bobbin carriage 8, the heat exchanger shell pass shell being connect with bobbin carriage 8
Body 1.Heat exchanger tube 2 is equipped in heat exchanger shell pass shell 1, heat exchanger tube 2 realizes shell side medium and tube side in heat exchanger shell pass shell 1
The cold and hot energy transmission of medium exchanges.Tube side medium enters the inner cold and hot medium of participation of heat exchanger shell pass shell 1 by heat exchanger tube 2
Heat transfer exchange.
The bobbin carriage 8 is equipped with inlet tube 91 and outlet 92, and pass partition cabinet 5 is equipped in the bobbin carriage 8 with by bobbin carriage 8
Separating is in top 81 and lower part 82, and the top 81 is connected to inlet tube 91, and the lower part 82 is connected to outlet 92.Type of thermal communication
It crosses inlet tube 91 and enters top 81, cold flow is discharged from lower part 82 by outlet 92.
Medium in bobbin carriage 8 is isolated in pass partition cabinet 5, and the tube side medium for having neither part nor lot in heat exchange is located at top
81, the tube side medium for having participated in heat exchange is located at lower part 82.
It is in vacuum state in the pass partition cabinet 5, to realize vacuum insulation effect, avoids not yet carrying out heat friendship
The medium changed and the heat transfer carried out between the medium that heat exchanges.
The pass partition cabinet 5 is equipped with sealing screw thread (not shown), further includes the sealing filament being threadedly coupled with sealing
Stifled 4.Pass partition cabinet 5 in bobbin carriage 8 is separated with the external world by sealing silk plug 4, needs to vacuumize in pass partition cabinet 5
When open it, tightened after vacuum is exhausted in pass partition cabinet 5, to remain true in pass partition cabinet 5
Dummy status.
