The place, two ends of the core component 1 on the stacking direction Y of pipe, two inserts 4 (side plate) are provided for strengthening core body component 1.For example, insert 4 is made by aluminium alloy.Insert 4 extends near the direction that is parallel to vertical X of pipe, and the end of insert 4 on the vertical X of pipe is connected with 3 with container 2.Insert 4 can have the thickness greater than pipe 10.
As shown in Figure 2, each container in the container 2 and 3 all comprises the central layer 20 that wherein inserts pipe 10 and insert 4, vessel 21 and the seal (not shown) that is used for forming with central layer 20 vessel space 2b.
For example, central layer 20 is made by aluminium alloy, and vessel 21 is made by resin (for example, the nylon 66 that glass fibre is strengthened), and seal is made by rubber.Seal is put between central layer 20 and the vessel 21, and a plurality of protruding parts 251 of central layer 20 are pressed on the vessel 21, thereby makes protruding part 251 plastic deformations, and vessel 21 is fixed to central layer 20.
To shown in Figure 5, central layer 20 has the pipe that connects pipe 10 and inserts plate member 22 as Fig. 3 A.Whole circumference place in that pipe inserts plate member 22 is provided with the groove 20a that has near rectangular shape.When vessel 21 and central layer 20 were fixed, the end of vessel 21 and seal inserted among the groove 20a.
Groove 20a is formed with inwall 23, diapire 24 and outer wall 25.Inwall 23 divides near vertical curve from the outer peripheral portion that pipe inserts plate member 22, and protrudes from diapire 24 on vertical X of pipe.Diapire 24 near vertical curve, and extends to the stacking direction Y of pipe or the principal direction Z of pipe from inwall 23.Outer wall 25, and protrudes from diapire 24 on vertical X of pipe near vertical curve from diapire 24.Protruding part 251 is formed at the place, end of outer wall 25.
The pipe of central layer 20 inserts plate member 22 and has a plurality of pores 221, and wherein pipe 20 inserts also hard solder in described pore.In addition, pipe inserts plate member 22 and has two patchholes 222, and wherein insert 4 inserts also hard solder in described patchhole.Patchhole 222 is arranged on the place, two ends that pipe inserts plate member 22 at the stacking direction Y of pipe.For example, pore 221 and patchhole 222 are gone up the elongated shape that extends by the principal direction Z that punching course is formed on pipe.In addition, pipe inserts a plurality of burr parts 221a that plate member 22 can be provided with the inner peripheral edge that is arranged on pore 221.For example, each burr parts 221a is the tubulose that has the cross section that is similar to pipe 10 and protrude into the inside (that is, protruding into the outside of pipe 10 at vertical X of pipe) of each container 2 and 3.
In addition, pipe inserts plate member 22 and has and be arranged between the adjacent pore 221 and in a plurality of rib shape portion 223 between pore 221 and patchhole 222 on the stacking direction Y of pipe.Rib shape portion 223 has the convex shape of extending and protrude into from pipe insertion plate member 22 outside of each container 2 and 3 at the principal direction Z of pipe.For example, rib shape portion 223 forms by press process.When the part between each adjacent pore 221 was set at mid portion, all mid portions all were provided with a pair of rib shape portion 223 of the principal direction Z that is arranged on pipe.
In addition, the end of rib shape portion 223 is away from inwall 23.Therefore, pipe insertion plate member 22 has two flat surfaces 224 that are positioned at pore 221, patchhole 222 and rib shape portion 223 outsides on the principal direction Z of pipe.Flat surfaces 224 spreads all over pipe at the stacking direction Y of pipe and inserts plate member 22 extensions.Flat surfaces 224 is the deformable component in vertical X easy deformation of pipe.
As mentioned above, at the stacking direction Y of pipe, have the gap betwixt and overlap each other in the end of the pore 221 of the principal direction Z of pipe and rib shape portion 223 with high rigidity.Therefore, when the temperature of a pipe 10 was different from the temperature of adjacent pipe 10, rib shape portion 223 prevented pore 221 in the distortion of the end of the principal direction Z of pipe, thereby confinement tube 10 is concentrated at the stress at the place, end of the principal direction Z of pipe.
In addition, the flat surfaces 224 that is positioned at pore 221, patchhole 222 and rib shape portion 223 outsides is easy to distortion at vertical X of pipe.Therefore, when the temperature difference between the pipe 10 was big, central layer 20 was because the distortion of flat surfaces 224 and in vertical X distortion of pipe, and the distortion of the thermal strain of pipe 10 by central layer 20 is absorbed.
In addition, the length L 1 of rib shape portion 223 is set at enough length, makes rib shape portion 223 in the distortion that reduces the end of pore 221 on pipe principal direction Z on the principal direction Z of pipe.In addition, set the length L 1 of rib shape portion 223, thereby improve the formability of rib shape portion 223.
When the ratio of the length L 1 of rib shape portion 223 and the length L 2 of pore 221 is set at greatly in 0.08≤(L1/L2)≤0.2 scope the time, rib shape portion 223 can reduce the distortion of the end of pore 221 fully, improves the formability of rib shape portion 223 simultaneously.
In addition, this to rib shape portion 223 at the stacking direction Y of pipe between adjacent pore 221 and patchhole 222.In other words, rib shape portion 223 is set to adjacent with the end of all pores 221, and wherein said end is adjacent at the stacking direction Y of pipe, deforms in each end of the principal direction Z of pipe thereby limit all pores 221.
(second embodiment)
In the central layer 20 of Fig. 3 B, all be provided with paired rib shape portion 223 at pore 221 and each mid portion between the patchhole 222 of the stacking direction Y of pipe.Alternatively, a part of mid portion can be provided with paired rib shape portion 223.For example, as shown in Figure 6, each all is provided with first mid portion of paired rib shape portion 223 and can be arranged alternately on the stacking direction Y of pipe without any second mid portion of rib shape portion 223.In other words, paired rib shape portion 223 can be arranged alternately in mid portion at the stacking direction Y of pipe.
Alternatively, be provided with in first mid portion of paired rib shape portion 223 one and without any two in second mid portion of the rib shape portion 223 stacking direction Y that can be arranged alternately at pipe.In other words, paired rib shape portion 223 can be arranged on a place in per three adjacent mid portions at the stacking direction of pipe.In the case, reduced the quantity of rib shape portion 223, compared, improved the formability of rib shape portion 223 thereby be arranged on each pars intermedia office with paired rib shape portion 223.
(the 3rd embodiment)
In the central layer 20 of Fig. 3 B, all be provided with paired rib shape portion 223 at pore 221 and each mid portion between the patchhole 222 of the stacking direction Y of pipe.Alternatively, each mid portion can be in distolateral the be provided with rib shape portion 223 of pore 221 at the principal direction Z of pipe.For example, as shown in Figure 7, can alternatively be arranged in the 3rd mid portion that first of pore 221 has a rib shape portion 223 on distolateral one and have in the 4th mid portion of a rib shape portion 223 one on distolateral at second of pore 221.At this, pore 221 first distolateral on the principal direction Z of pipe second distolateral relative with pore 221.Equally in the case, reduced the quantity of rib shape portion 223, compared, improved the formability of rib shape portion 223 thereby be arranged on each pars intermedia office with paired rib shape portion 223.
(the 4th embodiment)
In the central layer 20 of Fig. 3 B, in the mode that end and the rib shape portion 223 of the principal direction Z of pipe overlaps each other rib shape portion 223 is set on stacking direction Y, to make pore 221.Yet end and the rib shape portion 223 of pore 221 on the principal direction Z of pipe do not need to overlap each other at the stacking direction Y of pipe.
For example, rib shape portion 223 can be arranged on the outside of the end of pore 221 on the principal direction Z of pipe, to be in line on the principal direction Z of pipe with pore 221.As shown in Figure 8, every pair of rib shape portion 223 can aim at each pore 221, and has distance on the principal direction Z of pipe between described rib shape portion and described pore.
Equally in the case, near the stress that pore 221 is produced the end on the principal direction Z of pipe is distributed to rib shape portion 223, thereby makes the distortion of the end of rib shape portion 223 restriction pores 221.As a result, having limited the stress of locating at the both ends of pipe 10 concentrates.
In this embodiment, rib shape portion 223 is short in the length L 1 of the principal direction Z of pipe, thereby improves the formability of rib shape portion 223.In addition, even the distance between the adjacent pore 221 hour also can be provided with rib shape portion 223 at an easy rate.
(the 5th embodiment)
The central layer 20 that is used for according to the heat exchanger of fifth embodiment of the invention is described with reference to Fig. 9 A-10.The pipe of central layer 20 inserts a plurality of burr parts 221a that plate member 22 has the inner peripheral edge that is arranged on pore 221.Each burr parts 221a is the tubulose that has the cross section similar to the cross section of pipe 10 and protrude into the inside (that is, protruding into the outside of pipe 10 at vertical X of pipe) of each container 2 and 3.The rigidity of inserting the peripheral region of the pore 221 in the plate member 22 at pipe increases by burr parts 221a.On the contrary, burr parts 221a is not arranged in the patchhole 222.
In addition, pipe inserts plate member 22 and has a plurality of rib shape portion 223 that is arranged between the adjacent pore 221 and between pore 221 and patchhole 222.Rib shape portion 223 has the convex shape of extending and protrude into from pipe insertion plate member 22 outside of each container 2 and 3 at the principal direction Z of pipe.For example, rib shape portion 223 forms by press process.
The development length L1 of rib shape portion 223 is set at longer in the length of the principal direction Z of pipe than the length L 2 of pore 221 and patchhole 222.In addition, rib shape portion 223 is located in the outside of the end on pore 221 and the principal direction Z of patchhole 222 at pipe in the end on the principal direction Z of pipe.
In addition, the end of rib shape portion 223 is away from inwall 23.Therefore, pipe insertion plate member 22 has two flat surfaces 224 that are positioned at pore 221, patchhole 222 and rib shape portion 223 outsides at the principal direction Z of pipe.Flat surfaces 224 spreads all over pipe and inserts plate member 22 extensions on the stacking direction Y of pipe.Flat surfaces 224 is the deformable component in vertical X easy deformation of pipe.Therefore, when the temperature difference between pipe 10 was big, because the distortion of flat surfaces 224 causes the vertical X distortion of central layer 20 at pipe, the thermal strain of pipe 10 was absorbed by the distortion of central layer 20, thereby has reduced the stress of pipe 10 at the principal direction Z of pipe.
As mentioned above, burr parts 221a is arranged on the inner peripheral edge of pore 221, thereby has increased the rigidity of the peripheral region of the pore 221 in the pipe insertion plate member 22.Therefore, when the temperature of a pipe 10 is different from the temperature of adjacent pipe 10, the distortion of the end of burr parts 221a restriction pore 221, thus the stress at the end place of restriction pore 221 on the principal direction Z of pipe is concentrated.
In addition, burr parts 221a only is arranged on pore 221 places, and does not need to be arranged on patchhole 222 places, thereby has improved the formability of central layer 20.In addition, the thickness of insert 4 is thicker than the thickness of pipe 10, concentrates destruction thereby make insert 4 be difficult to be subjected to stress.Therefore, the stress that has limited the end place of pipe 10 on the principal direction Z of pipe is concentrated.As a result, limit the end distortion of pore 221 on the principal direction Z of pipe, improved the formability of central layer 20 simultaneously.
(the 6th embodiment)
When burr parts 221a is formed by press process, may in burr parts 221a, crack.Yet when being provided with when cutting part 221b by cutting a part of burr parts 221a in advance, burr parts 221a just is difficult to crack, and improves the formability of central layer 20.
In addition, the crackle of burr parts 221a in press process especially with the corresponding part of arch section 10b of pipe 10 in produce.Therefore, set in advance the time, just limited the crackle of burr parts 221a, and improved the formability of central layer 20 more with the part place of the corresponding burr parts of arch section 10b 221a when cutting part 221b.In addition, even when cutting with the corresponding a part of burr parts 221a of arch section 10b, burr parts 221a also can concentrate at the stress at the place, end of the principal direction Z of pipe confinement tube 10.Therefore, limit the stress at the place, end of pipe 10 at the principal direction Z of pipe and concentrated, improved the formability of central layer 20 simultaneously.
(the 7th embodiment)
Figure 13 is the cross-sectional view along the central layer that is used for heat exchanger according to a seventh embodiment of the invention 20 that line intercepted on the principal direction Z of pipe.Cut part 221b and tilt to flat surfaces 224, that is, and near surface tilt perpendicular to the central layer 20 of vertical X of pipe.Particularly, cutting part 221b tilts to compare the mode that the inner that cuts part 221b near the core of pore 221 is arranged on the inside of each container 2 and 3 with the outer end that cuts part 221b.
Different and when in pipe 10, producing thermal strain when the temperature of the temperature of a pipe 10 and adjacent pipe 10, at flat surfaces 224 with cut tie point (bending point) D distortion between the part 221b, be used to absorb thermal strain.The stress at the place, end of the pipe 10 on therefore, can the principal direction Z of confinement tube is concentrated.
Protrude near perpendicular to the central layer 20 of the vertical X of pipe surperficial the time when cutting part 221b, the length L that cuts part 221b 3 of protrusion is set at big in 0.05≤(L3/L2)≤0.3 scope with the ratio of the length L 2 of pore 221.Thereby the stress that has limited the place, end of the pipe 10 on the principal direction of pipe is concentrated, and has improved the formability of central layer 20 simultaneously.
When ratio (L3/L2) less than 0.05 the time, flat surfaces 224 and the tie point D that cuts between the part 221b are difficult to form.In addition, when producing thermal strain in pipe 10, tie point D is difficult to distortion, and may not absorb thermal strain.On the contrary, when ratio (L3/L2) greater than 0.3 the time, the end and the distance between the tie point D of the pipe 10 on the principal direction Z of pipe are elongated, thereby make tie point D may not absorb thermal strain in the pipe 10.
