Abstract
Description
- The present invention relates to a process for producing roll-bonded panels for use in heat exchangers such as refrigerator evaporators.
- It is already known to prepare a roll-bonded panel by printing a pattern corresponding to a fluid circuit on one surface of one of a pair of aluminum plates with a parting agent, superposing the other aluminum plate on the printed surface, roll-bonding the resulting assembly and thereafter inflating nonbonded portions to a tubular form with a fluid pressure. Roll-bonded panels of the type descrbied are in use which differ variously in circuit arrangement or passage width. The circuit of known panels includes, for example, a main passage and a hairpin shunt passage having a smaller width than the main passage and comprising a straight first shunt passageway branching from one portion of the main passage, a straight second shunt passageway branching from another portion of the main passage and a curved passageway provided between the two shunt passageways.
- When air of high pressure is applied to the nonbonded portion to produce a roll-bonded panel having such a hairpin shunt passage, the portion of main passage of large width is first inflated, and the portion of shunt passage is then inflated. In the shunt passage, the two straight shunt passageways are formed first, and the curved passageway is finally formed.
- The air of high pressure forming one of the straight shunt passageways by inflation therefore collides with the high-pressure air forming the other straight shunt passageway at the portion of curved passageway which is lower than the portions of straight passageways in pressure-resistant strength. Accordingly, the conventional roll-bonded panel formed with the hairpin shunt passage has the problem that the portion of curved passageway with a small curvature is ruptured by the impact involved in inflation, or is not inflated as designed since this portion is inflated finally. This problem becomes pronounced in producing roll-bonded panels which have a shunt passage of small width and require air of increased pressure for forming the circuit by inflation.
- An object of the present invention is to provide a process for producing roll-bonded panels free of faults such as the rupture of the curved passageway portion or failure in inflating the passageway portion as designed.
- The present invention provides a process for producing a roll-bonded panel having a fluid circuit by printing a pattern corresponding to the fluid circuit on one surface of one of a pair of aluminum plates with a parting agent, roll-bonding the aluminum plates with the other aluminum plate superposed on the printed surface, and thereafter inflating nonbonded portions to a tubular form with a fluid pressure, the fluid circuit including a main passage and at least one shunt passage smaller than the main passage in width, the shunt passage comprising a first shunt passageway branching from one portion of the main passage, a second shunt passageway branching from another portion of the main passage and a curved passageway provided between the two shunt passageways, the process being characterized in that the width of the nonbonded portion to be made into the first shunt passageway is different from the width of the nonbonded portion to be made into the second shunt passageway.
- With the process of the invention for producing roll-bonded panels, air of high pressure is applied to a nonbonded portion to form a circuit in the panel, whereby a main passage of large width is formed first by inflation, and a shunt passage is subsequently formed similarly. In forming the shunt passage by inflation, one of first and second shunt passageways which is larger in width is formed first, a curved passageway is then formed, and the other shunt passageway which is the smaller in width is finally formed (see FIG. 2). Accordingly, the process is free of the problem that the curved passageway portion will be ruptured by impact involved in inflation, and is also free of the problem of failure in inflating the curved passageway portion as designed because this portion is inflated finally.
- Preferably, the difference between the width of the nonbonded portion to be made into the first shunt passageway and the width of the nonbonded portion to be made into the second shunt passageway is not smaller than 0.2 mm.
- The present process is very effective in the case where a U-shaped passage or V-shaped passage is formed by a portion of the first shunt passageway proximate to the curved passageway, the curved passageway and a portion of the second shunt passageway proximate to the curved passageway.
- Preferably, air having a pressure not lower than 80 kg/cm² to not higher than 130 kg/cm² is introduced into the nonbonded portions for inflation.
-
- FIG. 1 is a perspective view showing an embodiment of roll-bonded panel obtained by the production process of the invention;
- FIG. 2 is a fragmentary plan view showing how a workpiece is inflated into the roll-bonded panel according to the invention;
- FIG. 3 is a plan view corresponding to FIG. 2 and showing how a conventional roll-bonded panel is formed; and
- FIG. 4 is a perspective view showing another embodiment of roll-bonded panel obtained by the production process of the invention.
- Embodiments of the present invention will be described below with reference to the drawings.
- FIG. 1 shows a roll-bonded panel obtained by the production process of the invention. The roll-bonded panel 1 is produced by printing a pattern corresponding to a fluid circuit on one surface of one of a pair of upper and lower aluminum plates with a parting agent (bonding preventing agent), roll-bonding the aluminum plates with the other aluminum plate superposed on the printed surface, and thereafter inflating nonbonded portions to a tubular form with air of high pressure introduced into these portions. This embodiment has an inflated tube on one side thereof over the entire area. The upper aluminum plate only is inflated, and the lower aluminum plate is flat.
- The fluid channel of the roll-bonded panel 1 comprises a
main passage 3 and ashunt passage 2 having a smaller width than themain passage 3. Theshunt passage 3 comprises first andsecond shunt passageways main passage 3 and parallel to each other, and acurved passageway 6 inerconnecting the forward ends of theseshunt passageways portion 4a of thefirst shunt passageway 4 proximate to thecurved passageway 6, thecurved passageway 6 and the portion 6a of thesecond shunt passageway 5 proximate to thecurved passageway 6. - The pattern of parting agent is so printed on the aluminum plate that the width W1 of the non-bonded portion to be made into the
first shunt passageway 4 is smaller than the width W3 of the nonbonded portion to be made into thestraight passage 3, and that the width W2 of the nonbonded portion to be made into thesecond shunt passageway 5 is smaller than the width W1 of the nonbonded portion to be made into thefirst shunt passageway 4. The pattern portion for forming thecurved passageway 6 is so printed that this portion gradually increases in width from thesecond passageway 5 toward thefirst passageway 4. The difference between the width W1 of the firststraight shunt passageway 4 and the width W2 of the secondstraight shunt passageway 5 is 0.3 mm. - When air with a pressure not lower than 80 kg/cm² to not higher than 130 kg/cm² is introduced into an
outlet 7 of the circuit to form the roll-bonded panel 1 by inflation, the circuit is inflated from portion to portion in the order of decreasing width. In the portion of thehairpin shunt passage 2, themain passage 3 is formed first, and thefirst shunt passageway 4 is then formed. Thesecond shunt passageway 5 is slightly smaller than thefirst shunt passageway 4 in width and is therefore formed later than thefirst passageway 4. After thefirst passageway 4 has been formed, accordingly, thecurved passageway 6 is formed first, and thesecond passageway 5 is formed finally (see FIG. 2). - For comparison, FIG. 3 shows how a conventional example is formed by inflation wherein first and second two
shunt passageways main passage 23 is formed first, and the twoshunt passageways curved passageway 26 is formed finally with a portion of high-pressure air from thefirst passageway 24 and with a portion of high-pressure air from thesecond passageway 25. Consequently, the air portions collide with each other in the portion ofcurved passageway 26, which is lower than the portions ofshunt passageways - With the embodiment shown in FIG. 2, the
second shunt passageway 5 is formed eventually by inflation, so that collision of high-pressure air portions produces an impact in thesecond passageway 5, whereas the portion of thesecond passageway 5 is unlikely to rupture since the portions ofpassageways curved passageway 6 in pressure-resistant strength. - FIG. 4 shows another embodiment of roll-
bonded panel 11 obtained by the production process of the present invention. With reference to this drawing, the roll-bonded panel 11 has a fluid circuit which comprises amain passage 13 and ashunt passage 12 with a smaller width than themain passage 13. Theshunt passage 12 comprises first andsecond shunt passageways main passage 12, and acurved passageway 16 interconnecting the forward ends of theseshunt passageways - The second embodiment differs from the first with respect to the following. The first and
second shunt passageways first passageway 14 proximate to thecurved passageway 16, thecurved passageway 16 and the portion of thesecond passageway 15 proximate to thecurved portion 16. Thefirst shunt passageway 14 is not straight and is held in communication with themain passage 13 by astraight passageway 14b connected to thepassageway 14 approximately perpendicular thereto. As in the first embodiment, a pattern of parting agent is so printed in this case that the width W4 of the nonbonded portion to be made into thefirst shunt passageway 14 is smaller than the width W6 of the nonbonded portion to be made into themain passage 13, and that the width W5 of the non-bonded portion to be made into thesecond shunt passageway 15 is smaller than the width W4 of the non-bonded portion to be made into thefirst passageway 14. This eliminates the faults that would otherwise occur in the portion ofcurved passageway 16. - With the foregoing two embodiments, the portion of curved passageway 6 (16) can be effectively rendered free from faults if the difference between the width W1 (W4) of the first shunt passageway 4 (14) and the width W2 (W5) of the second shunt passageway 5 (15) is not smaller than 0.2 mm. Preferably, the main passage 3 (13) is usually not smaller than 8 mm to not larger than 12 mm in width, and the second shunt passageway 5 (15), which has the smallest width, is not smaller than 4 mm in width.
