The specific embodiment
Following with reference to the description of drawings embodiments of the present invention.
(first embodiment)
Below, first embodiment that sees figures.1.and.2 to heat exchanger plate of the present invention describes.Fig. 1 is the approximate vertical view of the heat exchanger plate of present embodiment, and Fig. 2 is the partial sectional view of Fig. 1.
As shown in Figure 1, the heat exchanger plate of present embodiment is (hereinafter referred to as liner plate.) have main body 2 and cover 3.
Main body 2 for example is by oxygen-free copper or comprises Zr below 5% or the copper alloy of Cr is made, overlook rectangular plate-shaped member about long 2350mm, wide 2010mm, thick 15mm.And, on upper surface (surface) 2a of this main body 2, be provided with for example to overlook and be rectangular (first) groove 4 of U font, cross section or overlook groove in wave shape, that the cross section is rectangular 4.
Lid 3 is the plate-shaped members with plan view shape identical with groove 4, it forms, in the time of in embedded groove 4, the bottom surface 4a of its lower surface (back side) 3a and groove 4 joins, the two sides 4b of its two sides and groove 4 joins, and its upper surface (surface) 3c flushes (forming same plane) with the upper surface 2a of main body 2.And the central portion at this lid lower surface 3 of 3 is provided with rectangular (second) groove 5 in cross section that forms along two sides 3b.The space that forms when covering in 3 embedded grooves 4 (more specifically being the space that bottom surface 4a and groove 5 by groove 4 surround) becomes the stream 6 that cooling medium or heat medium pass through.
Main body 2 and lid 3 engage (Friction Stir Welding:FSW) by friction stir and engage.The friction stir joint is a method as shown in Figure 2: make throw 9 rotations with shoulder 7 and pin portion 8, insert the seam (boundary line: closing line), and make throw 9 move and engage along this seam of main body 2 and lid simultaneously.
When main body 2 and lid 3 engage by friction stir, at many (being 2 the in the present embodiment) streams 6 (between the groove 5 that forms on the lower surface 3a of the bottom surface 4a of the groove of overlooking to be the U font 4 and the lid 3 overlooking to be the U font formed stream 6 and overlook the bottom surface 4a of groove in wave shape 4 and overlook formed stream 6 between the groove 5 that forms on the lower surface 3a of lid in wave shape 3) independently separately of formation on the liner plate 1.And, behind joint, the inlet of cooling medium or heat medium is set in an end of each stream 6, the outlet of cooling medium or heat medium is set respectively in the other end of each stream 6.
According to the liner plate of present embodiment,, can reduce manufacturing cost on the upper surface 2a of main body 2 because the cross sectional shape of the groove 4 that processes is the simplest shape (rectangle), thereby can shorten the 4 necessary operations times of working groove.
And, be formed on the central portion that covers 3 lower surface 3a owing to form the groove 5 of stream 6, thereby when engaging, main body 2 and lid 3 be applied to the load that covers on 3, can be passed to the bottom surface 4a of groove 4, main body 2 just by the circumference of height and the degree of depth lid 3 about equally of groove 4, thereby the root pass that can prevent the junction surface enters stream 6, and can prevent to cause covering 3 distortion because of joint.
And then, because the degree of depth that lid 3 circumference forms height and groove 4 is about equally, thereby can improves and cover 3 whole rigidity, make the width of groove 5 become big, enlarge the width of stream 6, the sectional area of expansion stream 6.
(second embodiment)
According to Fig. 3 second embodiment of liner plate of the present invention is described.Fig. 3 is the partial sectional view of the liner plate of present embodiment, is the figure identical with Fig. 2.
The liner plate of present embodiment is provided with and covers 13, covers 3 to replace, and this point is different with above-mentioned first embodiment.Because other inscapes are identical with above-mentioned first embodiment, thereby in the explanation of this omission to these inscapes.
The parts identical with above-mentioned first embodiment adopt identical label.
Lid 13 is the rectangular plate-shaped members of overlooking of main body covered 2 entire upper surface 2a, long 2350mm, wide 2010mm.And, on lower surface (back side) 13a of this lid 13, be formed with protuberance 14.This protuberance 14 forms, and when lid 13 was superimposed with the upper surface 2a of main body 2, the bottom surface 4a of its end face 14a and groove 4 joined, and the two sides 4b of its two sides 14b and groove 4 joins.The space that forms in the time of in protuberance 14 embedded grooves 4 (space that is surrounded by the bottom surface 4a and the groove 5 of groove 4 in more detail) becomes the stream 6 that cooling medium or heat medium pass through.
Main body 2 and lid 13 engage (Friction Stir Welding:FSW) by friction stir and engage.The friction stir joint is a following method as shown in Figure 3: make throw 9 rotations with shoulder 7 and pin portion 8, insert simultaneously along thickness of slab direction main body 2 of extending and the seam (boundary line: closing line), and make throw 9 move and engage of covering 13 along this seam.
When main body 2 and lid 13 engage by friction stir, forming separately independently many (being 2 in the present embodiment) streams 6 (the end face 14a of the bottom surface 4a of the groove of overlooking to be the U font 4 and the protuberance 14 overlooking to be the U font goes up formed stream 6 between the groove 5 that forms and the last formed stream 6 between the groove 5 of formation of the end face 14a that overlooks the bottom surface 4a of groove in wave shape 4 and overlook protuberance in wave shape 14) on the liner plate.And, behind joint, the inlet of cooling medium or heat medium is set in an end of each stream 6, the outlet of cooling medium or heat medium is set respectively in the other end of each stream 6.
According to the liner plate of present embodiment,, can reduce manufacturing cost on the upper surface 2a of main body 2 because the cross sectional shape of the groove 4 that processes is the simplest shape (rectangle), thereby can shorten the 4 necessary operations times of working groove.
And, because the groove 5 that forms stream 6 is formed on the central portion of the end face 14a of protuberance 14, thereby when engaging, main body 2 and lid 13 be applied to the load that covers on 13, can be passed to the bottom surface 4a of groove 4, main body 2 just by the circumference of height and the degree of depth protuberance 14 about equally of groove 4, thereby the root pass that can prevent the junction surface enters stream 6, and can prevent to cause covering 13 distortion because of joint.
And then, because the degree of depth that the circumference of protuberance 14 forms height and groove 4 is about equally, thereby can improves and cover 13 whole rigidity, make the width of groove 5 become big, enlarge the width of stream 6, the sectional area of expansion stream 6.
In the present embodiment, also can be behind engage body 2 and lid 13, carry out grinding or grinding to covering 13 upper surface (surface), until state shown in Figure 2, promptly the whole surperficial 2a until main body 2 exposes, thereby reduces thickness of slab and use.
And heat exchanger plate of the present invention not only goes for the illustrated liner plate of above-mentioned embodiment, and also can be applicable to the structure with same formation and function in array formation operation.
