Definitions

  • the present invention relates in general to heat exchangers of motor vehicles, and more particularly to a tank of the heat exchangers, which generally comprises a tank body of clad metal, a pipe member of clad metal, a header plate member of clad metal and end plates of clad metal which are all hermetically secured to one another by means of brazing.
  • a conventional tank of heat exchanger which is disclosed in Japanese Utility Model First Provisional Publication 60-2195.
  • the conventional tank comprises a tank body 1 which has a pipe inserting opening 1a provided by means of a burring reamer.
  • a pipe member 2 is inserted into the pipe inserting opening 1a having Its leading end abutting on an inner surface of the tank body 1 through a seating plate 3.
  • usage of the seating plate 3 brings about a troublesome and time consuming work for producing the tank.
  • the tank needs a height "H" much greater than the diameter "D" of the pipe member 2, which causes a bulky construction of the tank.
  • FIG. 42 there is shown another conventional tank of heat exchanger.
  • the conventional tank comprises a tank body 1 produced by using a deep drawing technique, and a header plate member 4 brazed to the tank body 1.
  • the header plate member 4 is partially fixed or welded to the tank body 1 before carrying out the brazing.
  • different types of dies are needed depending on sizes and types of the tank produced by the deep drawing technique, and thus cost of the tank increases inevitably.
  • the tank is designed for radiators, the tank is obliged to have a larger height and longer structure making the deep drawing much difficult.
  • the longer structure of the tank makes the brazing between the tank body 1 and the header plate member 4 much difficult.
  • the parts 1 and 4 have to have complicated engaging and engaged portions 1a and 4a which are to be mutually engaged, which also brings about increase in production cost of the tank.
  • FIG. 43 there is shown still another conventional tank of heat exchanger, which is of a seam welded pipe type made of aluminum.
  • the tank shown in Fig. 42 has a rectangular cross section.
  • this conventional tank due to the tubular shape, formation of the opening in the tank for receiving and holding the pipe member needs a troublesome and consuming manual work.
  • a further conventional tank of heat exchanger which is made of aluminum.
  • the tank shown in the drawings comprises an aluminum tank body 1 having a generally C-shaped cross section and an aluminum header plate member 5 fitted to an open portion of the tank body 1.
  • each end plate 6 is formed with a rectangular recess 6a into which the corresponding end of the unit is press-fitted.
  • the recess 6a of the end plate 6 and the end of the unit are brazed at "R" in a furnace.
  • the tank body 1 becomes deformed as is shown by phantom lines. Of course, in this case, brazing of such deformed portion and the end plate is not adequately carried out.
  • the radiator 7 comprises upper and lower tanks 8 and 9 of plastics and a core structure 10 interposed between the upper and lower tanks 8 and 9.
  • the lower tank 9 has at Its lower surface mounting pins 11 by which the lower mount rubber 12 is held.
  • the lower mount rubber 12 is held by a lower bracket 13 extending from the vehicle body.
  • the upper tank 8 has at its upper surface mounting pins 14 by which the upper mount rubber 15 is held.
  • the upper mount rubber 15 is held by an upper bracket 16 extending from the vehicle body.
  • Fig. 47 shows a conventional technique for fixing each mounting pin 14 or 11 to the upper or lower tank 8 or 9.
  • the tank 8 or 9 is formed with an opening 8a
  • each mounting pin 14 or 11 is formed with a forked projected portion 14a.
  • the forked projected portion 14a is put in the opening 8a and then brazing is practically applied to mating portions therebetween.
  • this pin fixing work is troublesome.
  • satisfied brazing is not obtained by the pin due to a non-negligible difference in heat capacity between the mounting pin 14 or 11 and the tank 8 or 9.
  • the unsatisfied brazing tends to induce leakage of cooling water from the tank.
  • EP 0 821 213 A2 discloses securing inlet and outlet connectors to a header each of which is constituted of a generally rectangular-parallelepiped block.
  • the inlet and outlet connectors are provisionally fixed to the respective headers through argon arc spot welding and thereafter a tight assembling of the heat exchanger is achieved through brazing in a furnace.
  • a tank 100 of heat exchanger which is a first embodiment of the present invention.
  • the heat exchanger to which the tank 100 is practically applied is a radiator which is usually mounted in a front part of an engine room for cooling an engine cooling water.
  • the tank 100 of this first embodiment comprises a tank body 102 which is made of a clad metal, such as a clad aluminum plate or the like.
  • the tank body 102 is shaped like a channel member including opposed side walls 102a and 102b and an upper wall (or base wall) 102c.
  • the tank body 102 has a lower portion fully opened, as shown.
  • An inner surface of the tank body 102 is coated with a corrosion resisting material or self-sacrificing corrosion material, and an outer surface of the tank body 102 is lined with a brazing metal.
  • the side wall 102b is formed with a circular opening 104. As is seen from Fig. 1, the circular opening 104 has an uppermost end that terminates at an inner surface of the upper wall 102c.
  • a pipe member 106 is connected to the circular opening 104 of the tank body 102. That is, in operation, coolant is forced to flow in the pipe member 106 and the tank body 102.
  • the pipe member 106 is made of a clad metal, such as a clad aluminum plate or the like. Inner and outer surfaces of the pipe member 106 are coated with a corrosion resisting material or self-sacrificing corrosion material.
  • the pipe member 106 is formed at one end with an annular ridge 108 which functions to make a tight fitting of a hose (not shown) thereto when the hose is connected to the pipe member 106.
  • the other end of the pipe member 106 is formed with a generally circular flange 110.
  • the flange 110 comprises a generally circular major part which is brazed to a peripheral portion of the circular opening 104 of the side wall 102b and a generally arcuate upper part 110a which is bent at generally right angles and brazed to the upper wall 102c.
  • the pipe member 106 is produced by taking the following steps.
  • a clad aluminum plate 112 Is prepared.
  • the plate 112 is then subjected to a deep drawing process as is depicted by Figs. 4B, 4C and 4D to produce a cup-shaped member 114 with a roughly shaped flange 110.
  • the deep drawing process is carried out through three drawing steps.
  • the cup-shaped member 114 is subjected to a piercing process to provide at a bottom thereof with an opening 114a.
  • a peripheral portion of the opening 114a is bent or expanded outward as is indicated by short arrows in Fig.
  • the member 114 is subjected to a trimming process to remove an unnecessary part 110b. With this process, the flange 110 becomes shaped circular. Then, as is seen from Fig. 5D, one part 110a of the circular flange 110 is bent at right angles. Then, as is seen from Fig. 5E, the member 114 is subjected to an expansion process to provide the leading end thereof with an annular ridge 108. With this, the pipe member 106 is produced.
  • the pipe member 106 is partially fixed or welded to the tank body 102, as is understood from Fig. 1.
  • spot welding is applied to three portions P1, P2 and P3 of the unit of the tank body 102 and the pipe member 106, as is seen from Figs. 2 and 3.
  • other technique such as caulking, laser beam welding or the like may be used.
  • this semi-finished tank 100 is incompletely mounted to a core structure to provide a so-called semi-finished radiator (not shown), and then the semi-finished radiator is applied with a non-corrosive flux and heated in a furnace. With this, production of the radiator is finished completing brazing of various parts thereof.
  • the flange 110 is brazed to the tank body 102 in such a manner as has been described hereinabove.
  • the bent shape of the flange 110 of the pipe member 106 facilitates positioning and holding of the pipe member 106 to the tank body 102. That is, the right-angled arcuate part 110a of the flange 110 can be used as a suspending means for suspending the pipe member 106 on the tank body 102, as will be seen from Fig. 1. Since the uppermost end of the circular opening 104 of the side wall 102b is mated with the inner surface of the upper wall 102c of the tank body 102, the height needed by the tank body 102 for connecting with the pipe member 106 is reduced, which brings about a compact construction of the tank 100 and the associated radiator.
