Abstract

The utility model discloses a brazing sealing strip for a plate-fin heat exchanger. Sealing strips are connected with partition boards of the heat exchanger and fins through brazing, wherein the fins are arranged in a heat-exchanging cavity; one sides of the sealing strips are flat and straight; the other sides of the sealing strips are provided with convex strips; and the sealing strips are integrally connected with the convex strips. With the adoption of the brazing sealing strip for the plate-fin heat exchanger, the problem that the brazing is unfirm because the fins are easily held down by the sealing strips during the process of brazing the plate-fin heat exchanger can be solved, and accordingly, the phenomenon of leakage of a channel is avoided.

Description

Plate-fin heat exchanger is used the soldering strip of paper used for sealing
Technical field
The utility model relates to a kind of heat exchanger strip of paper used for sealing, in particular for the soldering strip of paper used for sealing of plate-fin heat exchanger.
Background technology
Plate-fin heat exchanger is a kind of compact heat exchanger equipment, and it is big to have a heat exchange area, the advantage that heat exchange property is good.During be widely used in empty branch, petrochemical industry, synthetic ammonia, natural gas liquefaction at present and separating etc. installed.Fin in the plate-fin heat exchanger heat exchanging chamber and dividing plate and strip of paper used for sealing link together through soldering; Owing to be easy to leave burr after the fin cutting; Therefore these burrs just may insert between strip of paper used for sealing and the dividing plate in brazing process, cause strip of paper used for sealing and dividing plate soldering not firm, and possibly cause revealing.Therefore, be necessary the structure of existing heat exchanger strip of paper used for sealing is optimized.
Summary of the invention
The purpose of the utility model provides a kind of fin burr of avoiding and inserts between strip of paper used for sealing and the dividing plate, causes strip of paper used for sealing and dividing plate soldering not firm, avoids heat exchanger channel the soldering strip of paper used for sealing of leakage phenomenon possibly occur.
In order to solve the problems of the technologies described above, the utility model is able to solve through following technical proposals:
Plate-fin heat exchanger is used the soldering strip of paper used for sealing, and strip of paper used for sealing and heat exchanger dividing plate and the fin that is arranged in the heat exchanging chamber are connected through soldering, and a side of strip of paper used for sealing is straight, and opposite side is provided with raised line, and strip of paper used for sealing and raised line are connected as a single entity.
As preferably, described raised line contacts with fin in the heat exchanging chamber.
As preferably, the cross sectional shape of described raised line is triangle or circular arc.
The utility model has significant technique effect owing to adopted above technical scheme:
The utility model strip of paper used for sealing and dividing plate soldering junction have been not easy the fin burr and have inserted, and have effectively reduced the possibility that the heat exchanger channel generation is revealed, and have very high practicality.

The specific embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing 1 to accompanying drawing 5:
Embodiment 1
Plate-fin heat exchanger is used the soldering strip of paper used for sealing, and like Fig. 2 and shown in Figure 5, strip of paper used for sealing 1 and heat exchanger dividing plate 2 and the fin 3 that is arranged in the heat exchanging chamber are connected through soldering; One side of strip of paper used for sealing 1 is straight, and opposite side is provided with raised line 4, and the cross sectional shape of raised line 4 is a triangle; Strip of paper used for sealing 1 is connected as a single entity with raised line 4, and raised line 4 contacts with the interior fin 3 of heat exchanging chamber, and raised line 4 can withstand fin; The burr of fin can not inserted between strip of paper used for sealing 1 and the heat exchanger dividing plate 2, guaranteed the quality of soldering.
Embodiment 2
Plate-fin heat exchanger is used the soldering strip of paper used for sealing, and like Fig. 3 and shown in Figure 5, strip of paper used for sealing 1 and heat exchanger dividing plate 2 and the fin 3 that is arranged in the heat exchanging chamber are connected through soldering; One side of strip of paper used for sealing 1 is straight, and opposite side is provided with raised line 4, and the cross sectional shape of raised line 4 is a circular arc; Strip of paper used for sealing 1 is connected as a single entity with raised line 4, and raised line 4 contacts with the interior fin 3 of heat exchanging chamber, and raised line 4 can withstand fin; The burr of fin can not inserted between strip of paper used for sealing 1 and the heat exchanger dividing plate 2, equally also guaranteed the quality of soldering.
In a word, the above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
