Both sides, the lateral surface of described strip of paper used for sealing body integrally formed with the second stress release portion that positive TV structure is "U" shape, described
The positive TV structure of the vertical portion of two stress release portions is in " ＞ " shape.
Above-mentioned novel strip of paper used for sealing, wherein, described first stress release portion is coated with polytetrafluorethylecoatings coatings.
Above-mentioned novel strip of paper used for sealing, wherein, the thickness of described polytetrafluorethylecoatings coatings is 0.3mm～1mm.
Above-mentioned novel strip of paper used for sealing, wherein, the upper head plate of described strip of paper used for sealing body and bottom plate are all covered with a solder flux thin film.
Above-mentioned novel strip of paper used for sealing, wherein, the thickness of described solder flux thin film is 2.5～5mm.
Technique scheme has the advantage that or beneficial effect:
The novel strip of paper used for sealing that this utility model provides passes through at medial surface integrally formed with one " mountain " shape the first stress release portion,
At lateral surface integrally formed with "U" shape the second stress release portion so that the cross section of strip of paper used for sealing is even variation, thus in welding
During, thermal stress can change along with the sectional uniform of strip of paper used for sealing, effectively prevent stress and concentrates on the overlap joint position of strip of paper used for sealing and dividing plate
Put, maximum stress concentrated position transferred to the pars intermedia of the first stress release portion, thus overcome welding strip of paper used for sealing, dividing plate and
During fin, use strip of paper used for sealing in prior art can cause dividing plate as easy as rolling off a log generation burn through and the problem of fracture, both avoided dividing plate and existed
Damage in welding, in turn ensure that the adhesion strength between strip of paper used for sealing and dividing plate, and the structure that is formed in one, overall construction intensity
Preferably.
Accompanying drawing explanation
The detailed description with reference to the following drawings, non-limiting example made by reading, this utility model and spy thereof
Levy, profile and advantage will become more apparent.The part that labelling instruction identical in whole accompanying drawings is identical.The most deliberately press
Accompanying drawing is drawn, it is preferred that emphasis is purport of the present utility model is shown according to ratio.
Fig. 1 is the Facad structure schematic diagram of the novel strip of paper used for sealing that this utility model embodiment 1 provides.
Detailed description of the invention
With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings, but not as this practicality
Novel restriction.
Embodiment 1:
Fig. 1 is the Facad structure schematic diagram of the novel strip of paper used for sealing that this utility model embodiment 1 provides；As it can be seen, this practicality
The novel strip of paper used for sealing that new embodiment 1 provides includes: strip of paper used for sealing body 101, the medial surface of strip of paper used for sealing body 101 is integrally formed with facing knot
Structure is the first stress release portion 102 of " mountain " shape, and the pars intermedia 1021 of the first stress release portion 102 is longer than the first stress release portion
The both sides 1022 and 1023 of 102, the lateral surface of strip of paper used for sealing body 101 is integrally formed with the second stress that positive TV structure is "U" shape
Release portion 103, the positive TV structure of the vertical portion 1031 of the second stress release portion 103 is in " ＞ " shape.By becoming in medial surface one
Type has one " mountain " shape the first stress release portion, at lateral surface integrally formed with "U" shape the second stress release portion so that strip of paper used for sealing
Cross section be even variation, thus in welding process, thermal stress can change along with the sectional uniform of strip of paper used for sealing, and effectively prevent should
Power concentrates on the lap position of strip of paper used for sealing and dividing plate, and maximum stress concentrated position is transferred to the pars intermedia of the first stress release portion,
Thus overcome when welding strip of paper used for sealing, dividing plate and fin, use strip of paper used for sealing in prior art can cause dividing plate as easy as rolling off a log generation burn through
With the problem of fracture, both avoided dividing plate damage in welding.
In the novel strip of paper used for sealing that this utility model embodiment 1 provides, the first stress release portion 102 is coated with polytetrafluoroethyl-ne
Ene coatings 104, the thickness of polytetrafluorethylecoatings coatings 104 is 0.5mm.Owing to being coated with polytetrafluoroethyl-ne on the first stress release portion
Ene coatings, thus when using the heat exchanger heat exchanging liquid applying this novel strip of paper used for sealing to carry out heat exchange, heat exchanging liquid will not adhere to
Inside strip of paper used for sealing, it is ensured that the clean-up performance inside strip of paper used for sealing, and then ensure that heat transfer effect.
