Abstract
The utility model discloses a novel short seal which comprises a left end face, a right end face, an upper brazing face and a lower brazing face, wherein one end face is a plane, the other end face is arranged into a chamfer W type opening, a protrusion extending outwards is arranged in the middle of the end face of the chamfer W type opening, and positions where the brazing faces and the two end faces are intersected are concave surfaces. By means of the arrangement of the chamfer W type opening end face, problem of loss of solders when the novel short seal is brazed is solved, so that brazing is firmer, percent of pass in each brazing process is improved, and at the same time, production cost is also reduced due to the W type opening.
Description
Technical field
The utility model relates to plate-fin heat exchanger, relates in particular to the short strip of paper used for sealing of a kind of chamfering type.
Background technology
The used short strip of paper used for sealing of plate-fin heat exchanger is generally plane transiens strip of paper used for sealing, by widespread usage.Yet its shortcoming has following problem: 1, because of its faying face is the plane, too small with the composite plate contact gap, the scolder ratio is easier to run off during soldering, is easy to generate the core body termination and leaks material; 2, product weight is overweight, increases the enterprise production cost.
The utility model content
The utility model provides a kind of novel short strip of paper used for sealing, is used for solving easy the loss and the too high problem of cost of short strip of paper used for sealing scolder of prior art plate-fin heat exchanger.
For solving the problems of the technologies described above, the novel short strip of paper used for sealing that the utility model embodiment provides, adopt following technical scheme:
A kind of novel short strip of paper used for sealing; Two end faces reached two faying faces up and down about this strip of paper used for sealing comprised; Wherein, an end face is the plane, and the other end is set to chamfering W type opening; Be provided with outward extending convexity in the middle of the said end face for chamfering W type opening, said faying face with about two end face intersections be concave surface.
The interior angle radian of said faying face and said end face intersection for the plane is 101 degree.
The interior angle radian of said faying face and said end face intersection for chamfering W type opening is 169 degree.
Said faying face with about the concave surface degree of depth of two end face intersections be 1.49-1.51mm.
Said be the protruding peak of end face of chamfering W type opening apart from said end face horizontal plane smaller or equal to 3mm.
A kind of novel short strip of paper used for sealing that the utility model provides, through the end face of chamfering W type opening is set, the problem that scolder runs off when having solved soldering makes soldering more firm, improves the disposable qualification rate of soldering, and W type opening also reduces production costs simultaneously.

The specific embodiment
A kind of novel short strip of paper used for sealing that the utility model embodiment provides, the easy loss and the too high problem of cost of short strip of paper used for sealing scolder that is used for solving the prior art plate-fin heat exchanger.
Below in conjunction with accompanying drawing the novel short strip of paper used for sealing that the utility model embodiment offers is described in detail.
Like Fig. 1, shown in 2; A kind of novel short strip of paper used for sealing, two end faces 11～12 reached two faying faces 2 up and down about this strip of paper used for sealing comprised, wherein; An end face (being the left side among the figure) 11 is the plane; Other end (among the figure for right side) 12 is set to chamfering W type opening, be provided with in the middle of the said end face 12 for chamfering W type opening outward extending protruding 121, said faying face 2 with about two end face 11～12 intersections be concave surface 3.
Said faying face 2 is 101 degree with the interior angle radian of said end face 11 intersections for the plane.
Said faying face 2 is 169 degree with the interior angle radian of said end face 12 intersections for chamfering W type opening.
Said faying face 2 with about concave surface 3 degree of depth of two end face 11～12 intersections be 1.49-1.51mm.
Said be chamfering W type opening end face 12 convexity 3 peaks apart from said end face 12 horizontal planes smaller or equal to 3mm.
A kind of novel short strip of paper used for sealing that the utility model provides, through the end face of chamfering W type opening is set, the problem that scolder runs off when having solved soldering makes soldering more firm, improves the disposable qualification rate of soldering, and W type opening also reduces production costs simultaneously.
The above; Be merely the specific embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field can expect changing or replacement in the technical scope that the utility model discloses easily, all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion by said protection domain with claim.
