Because the second hardware 3 consists of the structure identical with the first hardware 2, therefore, mark identical symbol, and omit detailed explanation.
The manufacture method of the radiator of present embodiment comprises preparatory process and bonding process.As shown in Figure 2 (a) shows, in preparatory process, the first hardware 2 and the second hardware 3 are configured in to pallet K above, and the end face 12,12 of base plate 11,11 is docked each other.In part after docking, be formed with docking section J.In addition, in the preparatory process of present embodiment, at the downside configuration back side of docking section J fitting 31.
In the present embodiment, the height dimension of back side fitting 31 is than the large 0.3mm of the height dimension of fin 21.In addition, in the present embodiment, horizontal line L and base plate 11 to become tilt angle alpha be 0.05 °.After having configured back side fitting 31, use holder (not shown) to be fixed, in order to avoid the first hardware 2 and the second hardware 3 move.
The tilt angle alpha of base plate 11 (height dimension of back side fitting 31) is entered heat etc. so long as considered that first hardware 2, second material of hardware 3, the size at each position and friction are stirred while engaging, make base plate 11,11 after thermal contraction occurs base plate 11,11 become smooth, and carry out suitably setting.
In addition, although also can make back side fitting 31 and pallet K split as present embodiment, also can make back side fitting 31 and pallet K be integrally formed.In this case, on pallet K, make the end face 12,12 of base plate 11,11 to fetching, form docking section J each other.
As shown in Fig. 2 (b), in bonding process, from the upper surface of base plate 11, docking section J is rubbed and stirs joint.Friction is stirred to engage and is used throw F.Throw F comprises columned shaft shoulder Fa and at the sagging pin Fb of the end face of shaft shoulder Fa.
In bonding process, make throw F mobile along the depth direction (Y direction) of docking section J, the first hardware 2 is engaged with the second hardware 3.As shown in Figure 3, on the motion track of throw F, be formed with plastification region W.Plastification region W is preferably in interior formation of length range of the short transverse (Z-direction) of docking section J.In addition,, for fear of the distortion of fin 21, plastification region W is preferably arranged to can not arrive the root of fin 21.After finishing bonding process, remove back side fitting 31.
After bonding process, the first hardware 2 and the second hardware 3 are taken off from holder, and standing.By this, in the W of plastification region, can there is thermal contraction, and the two ends of base plate 11,11 are out of shape in the mode of slightly lifting, thereby make base plate 11,11 become smooth.The deformation rate of base plate 11,11, the size at each position and the friction difference of entering heat etc. while stir engaging is different, but preferably makes tilt angle alpha become 0 ° because of the material of base plate 11 after finishing distortion.
In addition, in bonding process, use the throw more small-sized than throw F, the first hardware 2 and the second hardware 3 are engaged temporarily, in order to avoid produce very large breach (Japanese: order Open I) because of the insertion of pin Fb on the J of docking section.In addition, interim joint also can be undertaken by the mode of welding.
According to the manufacture method of radiator described above, before the stirring that rubs engages, make in advance the first hardware 2 and the second hardware 3 tilt separately, thereby can utilize the thermal contraction rubbing after stirring joint to improve the flatness of base plate 11,11.
The method that the first hardware 2 and the second hardware 3 are tilted is not particularly limited, but in the present embodiment, owing to making the first hardware 2 and the second hardware 3 tilt with back side fitting 31, therefore, as long as change the height dimension of back side fitting 31, just can easily regulate tilt angle alpha.In addition,, by back side fitting 31 is set, can support the downside of base plate 11,11, thereby can stably engage operation.
In addition, because the thickness ratio clearance D of back side fitting 31 is little, therefore, as shown in Figure 3, can be by the fin 21a that is configured in the first hardware 2 ends with to be configured in that gap between the fin 21a of the second hardware 3 ends is arranged to identical with the clearance D of 21 of other fin 21 and fins.By this, can make the heat transference efficiency of radiator 1 even.
(the second embodiment)
Then, the second embodiment of the present invention is described.In the manufacture method of the radiator of the second embodiment, different with the first embodiment on large this aspect of thickness of slab of base plate 11.
As shown in Figure 4, the first hardware 2 forms by base plate 11 with at a plurality of fins 21 that the lower surface of base plate 11 is arranged side by side.The structure of fin 21 is identical with the first embodiment.In base plate 11, the end face 12 relative with the second hardware 3 consists of outside end face 12a, inner side end 12b, median surface 12c.
The second hardware 3 is the structure identical with the first hardware 2.
In the manufacture method of the radiator of present embodiment, carry out preparatory process, the first bonding process, insert operation and the second bonding process.
As shown in Fig. 5 (a), in preparatory process, the first hardware 2 and the second hardware 3 are configured in to pallet K above, and outside end face 12a, 12a are docked each other.In part after docking, be formed with docking section J1.In addition, because outside end face 12a, 12a are docked, therefore, inner side end 12b, 12b are just relative across interval, thereby are formed with recess 13 by median surface 12c, 12c, inner side end 12b, 12b.
In addition,, in preparatory process, at the downside of docking section J1, dispose back side fitting 31.Back side fitting 31 is tabular components, its configuration of depth direction (Y direction) along docking section J1.Because the height dimension of back side fitting 31 is slightly larger than the height dimension of fin 21, therefore, if back side fitting 31 is configured in to the downside of docking section J1, base plate 11,11 run-off the straights, and docking section J1 is lifted gradually, and make docking section J1 uprise (becoming crest line).On the J1 of docking section, be formed with the small gap of V font, the lower edge of outside end face 12a is docked each other, upper limb is separated from each other.
In the second embodiment, as described later, owing to rubbing at three positions, stir and engage, therefore, enter heat more than the first embodiment.That is to say, in the second embodiment, because percent thermal shrinkage is larger than the percent thermal shrinkage in the first embodiment, therefore, the tilt angle alpha consisting of horizontal line L and base plate 11 is preferably set as larger than the tilt angle alpha in the first embodiment.After having configured back side fitting 31, use holder (not shown) to be fixed, in order to avoid the first hardware 2 and the second hardware 3 move.
As shown in Fig. 5 (b), in the first bonding process, by throw F is moved along the depth direction of docking section J1, the first hardware 2 is engaged with the second hardware 3.In addition,, in the first bonding process, after being preferably in and using throw F rub to stir joint, face cutting is carried out to so that it is level and smooth in the bottom surface of recess 13.By this, can not stay and configure with gap joint member 4 described later.
As shown in Figure 6 (a), in inserting operation, joint member 4 is inserted in recess 13.Joint member 4 is formed by the material identical with the first hardware 2 and the second hardware 3.In addition, joint member 4 is the shape roughly the same with the shape of recess 13.By the two sides of joint member 4 are docked with inner side end 12b, 12b, be formed with docking section J2, J2.
As shown in Figure 6 (b), in the second bonding process, by throw F is moved along the depth direction of docking section J2, J2, joint member 4 is engaged with the first hardware 2 and the second hardware 3.As shown in Figure 7, on the motion track of throw F, be formed with plastification region W2, W2.Plastification region W2 is preferably in interior formation of length range of the short transverse of docking section J2, J2.After finishing the second bonding process, remove back side fitting 31.
After the second bonding process, the first hardware 2 and the second hardware 3 are taken off from holder, and standing.By this, in plastification region W1, W2, W2, can there is thermal contraction, and the two ends of base plate 11,11 are out of shape in the mode of slightly lifting, thereby make base plate 11,11 become smooth.The deformation rate of base plate 11,11, the size at each position and the friction difference of entering heat etc. while stir engaging is different, but preferably makes tilt angle alpha become 0 ° because of the material of base plate 11 after finishing distortion.
In addition, also can be when the second bonding process, by throw F is moved back and forth with respect to joint member 4, recess 13 and the integral body at the interface of joint member 4 are rubbed to stir to be engaged.By this, can improve watertightness and the air-tightness at this interface.
According to the manufacture method of radiator described above, can obtain the effect roughly the same with the first embodiment.In addition, even if in the larger situation of the thickness of base plate 11, also can be by using joint member 4 periodically to engage in thickness of slab direction, thus can be in the situation that do not use very large throw to engage.By this, the suffered load of agitating device that can not only reduce to rub, and when joint is stirred in friction, can avoid causing greatly fin 21 distortion etc. because entering thermal change.
In addition, also can be after having carried out the first bonding process, under the state that the first hardware 2 and the second hardware 3 are taken off from holder, carry out the face cutting of recess 13.In this case, due to the first hardware 2 and the second hardware 3 are taken off from holder, therefore, can produce thermal contraction because of plastification region W1.Therefore, can expect using holder by the first hardware 2 after face cutting and the second hardware 3 again fixedly time, the tilt angle alpha of the horizontal line L of the tilt angle alpha that makes horizontal line L and base plate 11 before than the first bonding process and base plate 11 is little.
In addition, Fig. 8 means the front view of variation of manufacture method of the radiator of the second embodiment, and wherein, Fig. 8 (a) represents to insert operation, and Fig. 8 (b) represents the second bonding process.In variation, reduce the width of joint member 4A and recess 13A, by once rubbing, stir to engage and carry out the second bonding process.
As shown in Figure 8 (a), make the width of joint member 4A less than the width of the joint member of the second embodiment 4.Similarly, make the width of recess 13A less than the width of the recess of the second embodiment 13.In addition, make the width of joint member 4A and recess 13A slightly larger than the external diameter of the shaft shoulder Fa of throw F.
As shown in Figure 8 (b) shows, in variation, use the throw G larger than throw F, by once mobile, docking section J2, J2 rubbed and stir joint simultaneously.Make the external diameter of shaft shoulder Ga of throw G larger than the width of joint member 4A and recess 13A.On the motion track of throw G, be formed with plastification region W3.Plastification region W3 is best and plastification region W1 is overlapping.Even if use throw G, because being subject to friction, the position away from fin 21 stirs, and therefore, the frictional heat being produced by throw G can not impact fin 21.
(the 3rd embodiment)
Then, the 3rd embodiment of the present invention is described.In the manufacture method of the radiator of the 3rd embodiment, just in bonding process, the first hardware 2 and the second hardware 3 are engaged to this point with back side fitting 31A different with the first embodiment.

Back side fitting 31A is tabular, and configures along the depth direction of docking section J.The width of back side fitting 31A is as long as suitably set, but in the present embodiment, back side fitting 31A plays the effect of fin after joint, therefore, preferably has the width identical with other fin 21.In addition, fitting 31A in the back side is preferably set as identical with fin 21,21 interval each other with the interval of 21 of fins.
Because the lower end from back side fitting 31A is slightly larger than the height dimension of fin 21 to the height dimension of the lower surface (lower surface adjacent with back side fitting 31A) of base plate 11, therefore, if back side fitting 31 is configured in to the downside of docking section J1, base plate 11,11 run-off the straights, and docking section J1 is lifted gradually, and make docking section J1 uprise (becoming crest line).On the J1 of docking section, be formed with the small gap of V font, and the lower edge of outside end face 12a is docked each other, upper limb is separated from each other.
After having configured back side fitting 31A, use holder (not shown) to be fixed, in order to avoid the first hardware 2 and the second hardware 3 move.
As shown in Figure 10 (a) shows, in bonding process, by throw F is moved along the depth direction of docking section J1, the first hardware 2 and the second hardware 3 are engaged with back side fitting 31A.On the motion track of throw F, be formed with plastification region W.The insertion depth of throw F is as long as suitably set, but preferably the stirring that integrally rubbed of the bottom surface ( median surface 12c, 12c) of recess 13B and interface between the upper surface of back side fitting 31A engages.
After bonding process, the first hardware 2 and the second hardware 3 are taken off from holder, and standing.By this, in the W of plastification region, can there is thermal contraction, and the two ends of base plate 11,11 are out of shape in the mode of slightly lifting, thereby make base plate 11,11 become smooth.In addition, although larger than the height dimension of other fin 21 to the height dimension of the lower surface of base plate 11 from the lower end of back side fitting 31A, but also can directly use, can also cut the lower end of back side fitting 31A, so that the height of back side fitting 31A is identical with the height of other fin 21.
According to the manufacture method of radiator described above, can obtain the effect roughly the same with the first embodiment.In addition, as shown in Figure 10 (b), by the first hardware 2 and the second hardware 3 are engaged with back side fitting 31A, just can be by back side fitting 31A as fin.By this, can omit the time as the first embodiment, back side fitting 31 being removed.In addition, by forming recess 13B, back side fitting 31A stably can be configured.
In addition,, for the 3rd embodiment, be not limited to said method.In the present embodiment, form recess 13B, and back side fitting 31A is inserted to above-mentioned recess 13B, but also can omit recess 13B, and make lower surface and the back side fitting 31A butt of base plate 11,11.In addition, also the height of back side fitting 31A (from the lower end of back side fitting 31A to the height of the lower surface of base plate) can be set as to the height dimension identical with other fin 21.In this case, also the below of fitting 31A configuration dividing plate etc. regulates height overleaf, thereby the first hardware 2 and the second hardware 3 are tilted.In addition, also can be after having prepared back side fitting 31A, the upside of fitting 31A makes the first hardware 2 dock with the second hardware 3 overleaf, forms docking section J.
Above, embodiments of the present invention are illustrated, but also can in the scope without prejudice to aim of the present invention, suitably design change.For example, in the present embodiment, both tilt with identical angle to make the first hardware 2 and the second hardware 3, also can make both angles of inclination different.For example, also can make the side in the first hardware 2 and the second hardware 3 be level, and the opposing party is tilted.
In addition the method that, the first hardware 2 and the second hardware 3 is tilted is not limited to back side fitting 31.For example, both back side fitting 31 can be set, but by dividing plate is set between pallet K and fin 21, the first hardware 2 and the second hardware 3 are tilted, also can be at pallet K from arranging and tilt to make the first hardware 2 and the second hardware 3 to tilt with it.In addition, also can make near other the height of fin 21 of the aspect ratio of the fin 21 of docking section greatly, the first hardware 2 and the second hardware 3 are tilted.
