Definitions

  • the present invention relates to an improvement of an aluminum flat tube for heat exchanger with an inner fin inserted therein.
  • a refer­ence numeral 1 denotes an aluminum flat tube for heat exchanger, which is obtained through extrusion.
  • the flat tube 1 as shown in Fig. 6, wall surfaces 2, 3 coming in contact with a heat exchanger fin joined when a heat exchanger core is formed overhang mutually out­ward for easy insertion of an inner fin 4 as shown in Fig. 13. Then, the inner fin 4 is formed of a corruga­ted plate of pulse waveform.
  • the flat tube 1 and the inner fin 4 are unified, for example, as follows, thus forming a flat tube for heat exchanger.
  • the inner fin 4 is inserted in a space zone formed by both the wall sur­faces 2, 3.
  • both the wall surfaces 2, 3 are pres­surized to tighten a flat portion 5 in the horizontal direction of the inner fin 4 and insides of both the wall surfaces 2, 3, as shown in Fig. 14.
  • both the wall surfaces 2, 3 of the flat tube 1 are pressurized for inserting the inner fin 4 in the flat tube 1, however, if tightening efficiency of both the two is to be enhanced in this case, then the inner fin 4 is capable of being collapsed. If the inner fin 4 is collapsed, a flow resistance is increased, which is also not preferable. Accordingly, if the flat tube 1 is not pressurized thoroughly to prevent the inner fin 4 from being collapsed, both the wall surfaces 2, 3 are left overhanging outward, and cannot be piled up conse­quently at the time of core mounting in a post-process, which may deteriorate assembling efficiency. Further, such shape is not to ensure precision of fitting a seat plate in a hole, which is capable of causing a defective brazing.
  • the invention has for its object to solve the aforemen­tioned problems inherent in the prior art, and to pro­vide a flat tube for heat exchanger with inner fin in­serted therein, wherefore an assembling efficiency is en­hanced, and a predetermined shape is ensured, so that an inner fin can be inserted easily and securely in a flat tube, and a brazing of the flat tube to a seat plate can be carried out securely.
  • the flat tube will be formed tentative strictlyly by setting the inner fin on one aluminum plate member and then covering with another aluminum plate member to a unified body.
  • both the two can secure severelyly be joined, and a space desirable for inserting the in­ner fin therein can be secured. Consequently, the inner fin will never be collapsed when both aluminum plate members are joined, and a tightening efficiency of both aluminum plate members and the inner fin can be enhanced.
  • the flat tube is assembled tentatively by disposing ends of the inner fin on flat portions of the butt portions.
  • the inner fin since the flat portions of the butt portions hold ends of the inner fin there­between, the inner fin will never be contracted. Further, the inner fin projects outward from curved portions of the butt portions, therefore the flat tube can be brazed securely to the seat plate.
  • Fig. 1 is a perspective view of an aluminum flat tube for heat exchanger relating to the invention
  • Fig. 2 is a perspective view showing its assembling state.
  • a reference numeral 10 denotes an aluminum flat tube for heat exchanger relating to the invention, which comprises brazing integrally through normal process a pair of alu­minum plate members 20 with a brazing material clad on inner and outer surfaces and an inner fin 30 inserted when the pair of aluminum plate members 20 are put to­gether to form the flat tube 10.
  • the pair of aluminum plate members 20 have both side por­tions bent like a hook in the same direction to form bends 21, both nose portions formed flat, and both flat portions 22 made opposite on the same horizontal line. Then, the aluminum plate members 20 have an inside height H to be formed when put together set to be equi­valent to or somewhat smaller than a height h of the in­ner fin 30.
  • the inner fin 30 is then bent to a pulse waveform or the like.
  • the pair of aluminum plate members 20 and the inner fin 30 thus constructed are joined, for example, as follows and then brazed to the flat tube 10.
  • one of the aluminum plate members 20 has the inner fin 30 set thereon and then covered with the other aluminum plate member 20 to a uni­fied body.
  • the inner fin 30 is set on one of the aluminum plate members 20, which is then covered with the other aluminum plate member 20 from above to join, then since the height H of a space zone of both the two is set to be equivalent to or somewhat smaller than the height h of the inner fin 30 when the bends 21 of both the aluminum plate members 20 come in contact with each other, a force influential to cause a deformation on the inner fin 30 when both the aluminum plate members 20 are assembled will not be applied.
  • the flat portions 22 formed on the bends 21 of both the aluminum plate members 20 come in face con­tact with each other, these may function as a stopper to hold an interval between the two at a predetermined value when both the aluminum plate members 20 are as­sembled.
  • the flat por­tions 22 provided on the bends 21 of both the aluminum plate members 20 come in face contact with each other, therefore brazing at the portions can securely be carried out. Further, since inside wall surfaces 23 of both the aluminum plate members 20 and flat portions 31 of the in­ner fin 30 are put into face contact, brazing at the por­tions can be carried out also securely.
  • the aluminum flat tube 10 for heat exchanger is formed by setting the inner fin 30 in one of the aluminum plate members 20, then putting the re­maining aluminum plate member 20 thereon, assembling next tentatively with a desired jig to brazing, thus avoiding unnecessary measures prevailing hitherto as pressurizing tube material when the inner fin is insert­ed, preventing the inner fin from being collapsed when pressurized and so forth.
  • the aluminum flat tube 10 for heat exchanger manufactured according to the above-described embodiment is fitted on seat plates 51 shown, for example, in Fig. 3 to Fig. 5 to form a heat exchanger core 50.
  • the seat plate 51 is provided with a burring hole 52 according to an outline of the aluminum flat tube 10 for heat ex­changer.
  • both the aluminum plate members 20 forming the flat tube 10 are bent like a hook, that is, a projection discharged inwardly when both the two are joined is formed, the projection functions as an inner fin.
  • the projection functions as an inner fin.
  • another stir­ring effect from that by the inner fin 30 is obtained, a contact efficiency of the flat tube 10 with a coolant can be enhanced in the flat tube 10, thus improving a ra­diating performance.
  • a material with a brazing material clad on inner and outer surfaces of the tube is employed, however, that of having a brazing material clad on the outer surface and another brazing material clad on both surfaces of the inner fin may be employed otherwise.
  • the inner fin may be shaped differ­ently from that of the embodiment.
  • a side-flow type heat exchanger has been taken up for description, however, the invention is not necessarily limited there­to, and hence a down-flow type heat exchanger may be exemplified therefor.
  • the invention can be ap­plied not only to an intercooler for vehicle but also to heat exchangers such as radiator, heater core, evapora­tor, condenser and the like.
  • the fin in­serted on outside of the flat tube 10 for heat exchanger relating to the invention may be a plate fin other than the corrugated fin so specified in the above-described embodiment.
  • the invention in a tube for heat exchanger com­prising an aluminum flat tube with a brazing material clad on the outer surface, an inner fin inserted in the aluminim flat tube, the invention relates to an aluminum flat tube for heat exchanger comprising a pair of alumi­num plate members with both side portions bent like a hook in the same direction to form bends, both nose por­tions formed flat, both the flat portions made opposite on the same horizontal line, and with a brazing material clad at least on the outer surface, an inner fin insert­ed when the pair of aluminum plate members are put to­gether to a flat tube, wherein the pair of aluminum plate members are put together to have the inner fin in­serted therein, and then brazed with the flat portions of the bends joined therefor, and hence it can be formed so that both wall surfaces of the flat portions other than both ends will be almost parallel, these can thus be piled up in parallel at the time of assembling work, therefore not only storage and management will be facil­itated,
  • a flat tube body side need not be kept overhanging outward beforehand for inserting the inner fin, therefore a forming process can be simplified.
  • one of the aluminum plate members has the inner fin set therin beforehand and then covered with the remaining aluminum plate member, therefore the inner fin can be set easily in the flat tube without be­ing collapsed.
  • both aluminum plate members and inner fin are kept coming in face contact with each other, a thermal conductivity is very good, and a radiating performance of a coolant circulating in the flat tube is enhanced.
  • an inward swelling por­tion formed by bends of both the aluminum plate members functions as an inner fin, therefore a radiating perform­ance can further be enhanced.
  • a roll forming is ready from rolled materials and a plate thickness to­lerance can be minimized as compared with a hot extruded material, therefore it can be thinned in an average thick­ness to a merit on the premise that a strength is ensured on the minimum thickness.
  • sacrificial preserva­ tives 7072 material and the like
  • Fig. 6 and Fig. 7 represent a flat tube for heat exchang­er with inner fin inserted therein which is given in one embodiment of the invention, wherein a reference numeral 61 denotes an aluminum flat tube, and an inner fin 63 is inserted in the flat tube 61.
  • the flat tube 61 has a pair of tube semimembers 65, 66 put together therefor in construction.
  • Each of the tube semimembers 65, 66 has curved portions 67 curved inward formed on both sides thereof, and flat portions 69 running inward are formed on ends of the curved portions 67. Butt portions are formed by the curv­ed portions 67 and the flat portions 69. Then, a brazing material 71 is clad, as shown in Fig. 7, on outer sur­faces of the tube semimembers 65, 66.
  • the inner fin 63 consists of a corru­gated plate, and a held portion 73 wrought flat is form­ed on both sides thereof.
  • a width of the held portion 73 is made somewhat longer than the width of the flat por­tions 69 of the tube semimembers 65, 66.
  • the held portion 73 of the inner fin 63 is placed on the flat portion 69, and then with the flat portion 69 facing downward, the upper side tube semimem­ber 65 is put thereon, that is to say, the pair of tube semi­members 65, 66 are put together through the held portion 73 of the inner fin 63, thereby assembling the flat tube 61 tentatively. Then, the held portion 73 of the inner fin 63 is left protruding somewhat outward, in this case, from the curved portions 67 of the tube semi­ members 65, 66.
  • the flat tube 61 assembled tentatively as above is inserted in a burring hole 77 formed on a seat plate 75, as shown in Fig. 8 and Fig. 9, straight or after assembl­ed regularly through brazing in a furnace according to normal process, brazed in a furnace together with a cor­rugated fin 79, and thus a core part is assembled.
  • the flat tube 61 can be brazed to the seat plate 75 securely.
  • Fig. 11 represents another embodiment of the invention, wherein a flat tube 83 is constructed by bending a sheet of plate 85, and a butt portion consisting of the curved portions 67 and the flat portions 69 is formed on both ends of the plate 85. Accordingly, the butt portion is formed only on one side of the flat tube 83.
  • the flat tube is constructed by putting together a pair of tube semimem­bers or by bending a plate, the butt portions are formed of curved portions curved inward and flat portions run­ning from ends of the curved portions, the inner fin is inserted between the flat portions of the butt portions at both sides or one side thereof, further the inner fin is projected outward from the pair of flat portions oppo­site each other at both sides or one side thereof, there­fore the inner fin can be inserted easily and securely in the flat tube, and the flat tube can be brazed to the seat plate securely, too.
