As it can be seen that whether the scheme of small flange or silk adapter tube road, maximum problem cannot when being site installation test
It realizes that concentricity not can guarantee well to the heart, directly results in the unstability of equipment operation.
Existing scheme all proposes respective resolving ideas to foregoing problems, also achieves some examples, solution party respectively
Case can substantially be divided into two classes, and in adverse current and mixed flow enclosed tower, the first is generally made into integrated heat exchanger to cope with, with carbon
Steel pipe integral solder and the form of galvanizing solve foregoing problems；Second with cabinet plus is changed using heat exchanger housing of tube
The form of heat pipe integral solder solves the above problems.Second scheme is identical as the first principle, only more applies
Cross flow cooling tower.
But it facts have proved both the above scheme without completely solving the problems, such as to have already appeared, there are costs substantially to rise
High, material there are limitation, the problems such as existing tower can not be applied directly to, do not obtain large-scale application or only exist
Specific occasion application.
Therefore, how to overcome heat exchange coil to be connected with circulating water pipeline existing disadvantages described above, be skilled person
The technical issues that need to address.

Further, optional there are many material due to clip washer 13-1, the requirement of all multimediums of curstomer's site can be coped with；
Moreover, integral solder amount does not increase with current programme, more reduce the difficulty of processing of related pipe fitting, reduces the same of cost
When, have many advantages, such as that debugging is easy, stable, pressure-bearing is high.
In addition, because the overall heat exchange device combination after installation can be supported individually, therefore overhaul difficulty and do not increase.
Above-described embodiment is only the preferred embodiment of the utility model, is specifically not limited thereto, on this basis can basis
Actual needs is made having and targetedly be adjusted, to obtain different embodiments.For example, the quantity of heat exchanger coils 12 is not
Four groups are confined to, can further increase also or reduce, or even be reduced to one group, alternatively, in order to be connected with other component, circulation
Only one end is the clamp connection end equipped with annular slot 11-2 to water supervisor's segmentation 11-1, and the other end is non-clamp connection end, and or
Person, recirculated water are responsible for 11 lateral arrangements, etc..Since mode in the cards is more, just no longer illustrate one by one here.
In addition to above-mentioned heat exchanger assembly and heat exchanger, the utility model also provides a kind of closed cooling tower, including tower body and
Set on the heat exchanger of tower body, wherein heat exchanger is equipped with heat exchanger assembly above, alternatively, heat exchanger is heat exchange above
Device, about remaining structure of closed cooling tower, refer to the prior art, and repeats no more herein.
Heat exchanger assembly provided by the utility model, heat exchanger and closed cooling tower are described in detail above.
Specific case used herein is expounded the principles of the present invention and embodiment, and the explanation of above embodiments is only
It is the core concept for being used to help understand the utility model.It should be pointed out that for those skilled in the art,
Without departing from the principle of this utility model, several improvements and modifications can be made to this utility model, these improvement
It is also fallen into the protection scope of the utility model claims with modification.
