Description
Technical field
The utility model is related to a kind of improved technologies of radiator, can prevent internal leakage more particularly to one kind and eliminate
The improved technology of the tubular radiator of thermal (temperature difference) stress.
Background technology
Radiator is a kind of compact heat-exchange apparatus being made of heat exchanger tube, bobbin carriage, tube sheet, boxboard etc., in metallurgical, food
The fields such as product, chemical industry, steel are widely used.Its finned tube of traditional radiator is to be fixedly connected with tube sheet, bobbin carriage
And the material chosen is different, causes swell increment different from the temperature difference of babinet due to heat exchanger tube in heat transfer process, so as to cause
There is exchanger tubes and tubesheets weld larger thermal (temperature difference) stress, the presence of the thermal (temperature difference) stress to easily cause weld bond cracking, cause
It leaks and loses heat transfer effect.Once a leak occurs, the medium in tube side will leak into air side, air side pollution effect is caused to change
Heat.Cause to be seriously affected using radiator enterprise product quality, especially in some special operating modes, such as steel plate plating
In the technique of zinc, it is desirable that medium in pipe is forbidden to enter air side.For a long time, which can not solve due to the swell increment not
With the thermal (temperature difference) stress problem of caused exchanger tubes and tubesheets weld so that the problem becomes long-term and thirsts for solving but always not yet
The technical barrier of solution.
Invention content
The purpose of this utility model is to provide a kind of radiators for having and thermal (temperature difference) stress being leaked and eliminated in anti-.Mainly solve
Certainly existing radiator is existing to cause weld bond to crack due to the thermal (temperature difference) stress at fin tube to tube sheet welding, and radiator is caused to be let out
The problem of leakage.So that serious hope for a long time is solved, but still unsolved technical barrier is solved always.
The technical solution of the utility model is as described below：The utility model includes by U heat exchange, medium entrance, medium
Outlet, air intlet, air outlet slit, bobbin carriage, tube sheet, left side boxboard, right side boxboard and cover board and the U-tube of end cap composition dissipate
Hot device mainly by the way that parallel the first tube sheet and the second tube sheet are arranged on the inside of the bobbin carriage of U heat exchange, and makes the first pipe
The anti-interior leakage cavity of formation one between plate, the second tube sheet and babinet is additionally provided with discharging hole in the anti-interior leakage cavity bottom.Wherein
The U heat exchange is that intensity weldering connects with the first tube sheet, is that intensity expanded joint connects, and welds shape with left side boxboard with the second tube sheet
Integral fixed structure.
The beneficial effects of the utility model：Due to taking the anti-interior leakage cavity body structure being arranged on the inside of bobbin carriage, once it is U-shaped
Heat exchanger tube and the first tube sheet Joint failure, medium can leak into the anti-interior leakage cavity formed between the first tube sheet and the second tube sheet
In, it can be discharged by discharging hole.Without leaking into the cavity of air side, to realize leakage in anti-.Due also to U heat exchange,
The whole fixed structure form of first, second tube sheet, left side boxboard, and U heat exchange across hole structure right side boxboard and
It is not welded with it, keeps U heat exchange free to slide in horizontal axis direction, to eliminate the swell increment caused by temperature difference
The thermal (temperature difference) stress of exchanger tubes and tubesheets weld caused by difference, keeps the connection of U heat exchange and tube sheet relatively reliable.Simultaneously
With inventive concept it is novel, simple in structure it is applicable, stable and reliable for performance, ensure product quality, realize continuous production, increase economy
The advantages that benefit, suitable industry are promoted.
Description of the drawings
Fig. 1 is with the anti-interior radiator overall structure diagram leaked and eliminate thermal (temperature difference) stress.
Specific implementation mode
The radiator shown in FIG. 1 for having anti-interior leakage and eliminating thermal (temperature difference) stress is that one kind is set on the basis of prior art construction
A kind of novel heat exchange equipment of meter.It is medium inlet and outlet 1,1 ' on the left of it, medium inlet and outlet 1,1 ' is fixed on 2 outside of bobbin carriage
On cover board 3, the inside of bobbin carriage 2 is equipped with parallel the first tube sheet 4, the second tube sheet 4 ' and left side boxboard 5, and U heat exchange 6 passes through the
One, the hole on second liang of tube sheet 4,4 ' and left side boxboard 5 takes to weld connecting with the first tube sheet semi-finals degree, is strong with the second tube sheet 4 '
Degree expanded joint connects；And it is whole fixed with left side boxboard 5.At the same time, one is formed between first, second liang of tube sheet 4,4 ' and babinet
A anti-interior leakage cavity is additionally provided with discharging hole 7 in the anti-interior leakage cavity bottom.The right side of left side boxboard 5 is air cavity, up and down
Equipped with air outlet slit 8 ' and air intlet 8, end is end cap 9, and 9 inside of end cap is equipped with right side corresponding with left side boxboard 5 boxboard
5 ', U heat exchange 6 is passed through and right side boxboard 5 ' but is not welded with it, by right side boxboard 5 ' by its Right side support.
When work, liquid medium is from U heat exchange（That is tube side）6 imports 1 enter, 1 ' outflow radiator of outlet, and in sky
Air cavity（That is shell side）In be passed through air, heat is swapped in the process.If U heat exchange 6 and the first tube sheet 4 by
Cause weld bond to crack in thermal (temperature difference) stress, can be realized by leakage cavity in anti-and leak function in anti-, can also by U heat exchange, first,
The whole fixed form of second tube sheet, left side boxboard, further eliminates the thermal (temperature difference) stress, keeps performance relatively reliable.
