Abstract
The invention discloses a heat exchange plate easy to weld, which comprises an L-shaped plate and an H-shaped plate, wherein a first concave-convex stripe is formed on the L-shaped plate in a stamping mode, a second concave-convex stripe is formed on the H-shaped plate in a stamping mode, the first concave-convex stripe and the second concave-convex stripe are both in a V shape with a lower middle part and an upward extending outer part, the included angle between the outer side part of the first concave-convex stripe and a horizontal line is alpha, the included angle between the outer side part of the second concave-convex stripe and the horizontal line is beta, alpha is larger than beta, the outer side part of the first concave-convex stripe is connected with an extending concave-convex stripe, the included angle between the extending concave-convex stripe and the horizontal line is theta, and the theta. The invention has the advantages that: easy welding and good quality after welding.
Description
Technical Field
The invention relates to the technical field of heat exchange, in particular to a heat exchange plate easy to weld.
Background
Heat exchange fins made of metal plates such as copper plates and the like are widely used in a plurality of devices at present. The heat exchange plate can be divided into an L-shaped plate and an H-shaped plate according to the gradient of the concave-convex patterns formed by stamping on the heat exchange plate. In some cases, it is desirable to weld the edges of the L-shaped panels and the H-shaped panels together for use. At this moment, because the concave-convex pattern on L template and the H template has different slopes to difficult location, and the limit portion of welding back L template and H template has different resilience force, causes welding quality relatively poor.
Disclosure of Invention
In view of the above-mentioned shortcomings of the prior art, the present invention aims to provide an easily welded heat exchanger plate, which has the characteristics of easy welding and good quality after welding.
In order to achieve the purpose, the invention adopts the technical scheme that: easy welded heat transfer board, including L template and H template, be formed with first unsmooth stripe through the mode of punching press on this L template, be formed with second unsmooth stripe through the mode of punching press on this H template, first unsmooth stripe and second unsmooth stripe all are that the middle part is lower, outside upwards extends "√" shape, and the outside portion of first unsmooth stripe and the contained angle of horizontal line are alpha, and the outside portion of second unsmooth stripe and the contained angle of horizontal line are beta, and alpha > beta, the outside portion of first unsmooth stripe is connected with extends unsmooth stripe, and the contained angle that extends unsmooth stripe and horizontal line is theta, and theta ═ beta.
After adopting the structure, compared with the prior art, the invention has the advantages that: easy welding and good quality after welding. According to the easily-welded heat exchange plate, the extending concave-convex stripes are formed on the outer side parts of the first concave-convex stripes on the L-shaped plate, and the extending direction of the extending concave-convex stripes is the same as that of the second concave-convex stripes on the H-shaped plate, so that when the L-shaped plate and the H-shaped plate are welded together, the outer parts of the second concave-convex stripes and the extending concave-convex stripes are welded together, and the edges of the two identical H-shaped plates are welded together, so that the easily-welded heat exchange plate is convenient to position, the phenomenon of different resilience after welding is greatly avoided, the welding firmness degree is ensured, and the quality is.
Drawings
The invention is further illustrated with reference to the following figures and examples:
FIG. 1 is a front view of an L-shaped panel of the present invention;
FIG. 2 is an enlarged view of portion A of FIG. 1;
FIG. 3 is a front view of the H-shaped panel of the present invention;
fig. 4 is an enlarged view of a portion B of fig. 2.
Detailed Description
In the following embodiments, the uneven stripes (including the first uneven stripe, the second uneven stripe, and the extended uneven stripe) refer to stripes formed on the copper plate, which protrude from the front surface of the copper plate and protrude from the rear surface of the copper plate, or protrude from the front surface of the copper plate and protrude from the rear surface of the copper plate, after the thin copper plate is stamped by using a die. Obviously, the convex and concave strips must be adjacent to each other for the same face of the copper plate. And the concavo-convex stripes refer to a general term of convex stripes and concave stripes.
Examples, see fig. 1-4: the heat exchange plate easy to weld comprises an L-shaped plate 10 and an H-shaped plate 20, wherein a first concave-convex stripe 11 is formed on the L-shaped plate 10 in a stamping mode, and a second concave-convex stripe 21 is formed on the H-shaped plate 20 in a stamping mode. Each of the first concave-convex stripe 11 and the second concave-convex stripe 21 has a "v" shape with a lower middle portion and an upward extension outside. An angle between the outer side portion of the first uneven stripe 11 and the horizontal line is α, an angle between the outer side portion of the second uneven stripe 21 and the horizontal line is β, and α > β. That is, the extending direction of the outer portion of the first uneven stripe 11 is steeper than the extending direction of the outer portion of the second uneven stripe 21 as viewed from the front.
Further speaking:
an extended uneven stripe 12 is connected to an outer side portion of the first uneven stripe 11, an angle between the extended uneven stripe 12 and a horizontal line is θ, and θ is β. That is, the outer end of the first uneven stripe 11 is bent downward to form the extended uneven stripe 12, and the included angle between the extended uneven stripe 12 and the horizontal line and the included angle between the second uneven stripe 21 and the horizontal line tend to be consistent. In this way, the edges of the L-shaped plates 10 and the H-shaped plates 20 are easily welded together, and the welding quality is relatively good.
The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
