Description
Technical field
The present invention relates to a kind of heat-exchange systems of lamella heat exchanger composition.
Background technique
Lamella heat exchanger has compact-sized, the big outstanding advantage of heat transfer area in light-weight and unit volume.Make
With middle discovery, since shell side path is short and shell-side flow path height is big, existing lamella heat exchanger shell-side fluid flow velocity is far low
In plate journey velocity of medium, heat exchange efficiency is leveraged.In addition, the feature narrow due to the intrinsic shell-side flow path of shell-and-plate, plate
Piece outer surface is easy to fouling, and removes more troublesome after fouling, and shell-side fluid flow velocity is low has aggravated plate fouling.
On the other hand, since plate is generally prepared by edge welding, when the plate shell-side fluid temperature difference is larger, weld seam meeting
By biggish cold and hot transformation stress, part is cracked, and influences the normal work of heat exchanger.Therefore, existing lamella heat exchanger
There are a conspicuous contradictions in use, and heat exchange efficiency is difficult to reach requirement if the plate shell-side fluid temperature difference is small, and if increased
Add the temperature difference to improve heat exchange efficiency then and will lead to the plate lost of life, or in turn to plate welding process requirement excessively harshness
There is the excessively high problem of plate manufacturing cost.
Summary of the invention
The technical problem to be solved by the invention is to provide a kind of shell-and-plate high flow rate stepped heat exchange systems, pass through raising
Shell-side fluid flow velocity achievees the purpose that improve heat exchange efficiency, and better solves the dirty stifled and scale problems of plate.Institute of the present invention
Second technical problem to be solved is to reduce impact of the cold and hot transformation stress to plate weld seam by stepped heat exchange, thus real
Now big temperature difference heat exchange.
Technical scheme is as follows:
