Definitions
- the present invention relates to a tank structure of a heat exchanger such as a radiator that is adapted for a motor vehicle.
- Japanese Patent Applications Laid-Open Publication No. 2005-299989 and No. 2005-326100 disclose a technology of conventional tank structures of heat exchangers in which both end portions of a plurality of tubes are inserted into and fixed to a bottom portion of a tank that is made of aluminum material.
- the conventional inventions have a problem in that they cannot improve coolability of the heat exchangers, because the tubes of the heat exchangers are limited to thin ones for the reason that the tanks thereof could have been deformed to expand outwardly due to thermal shock generated when each tube thereof thermally expands and contracts in a longitudinal direction thereof.
- the present invention is made to solve the above-described problem, and its object is to provide a tank structure of a heat exchanger that can prevent a tank from being deformed due to thermal shock generated when each tube of a heat exchanger thermally expands and contracts in a longitudinal direction thereof.
- a tank structure of a heat exchanger in which end portions of a plurality of tubes are inserted in and fixed to a bottom portion of a tank that is made of aluminum material, where the tank structure is characterized in that a bead is provided at a position of a tube side heading from a half position of a height of a side wall portion of the tank to extend in a direction perpendicular to a longitudinal direction of the tubes.
- a tank structure of a heat exchanger in which end portions of a plurality of tubes are inserted in and fixed to a bottom portion of a tank that is made of aluminum material, where the tank structure is characterized in that the tank is formed like a vessel to open toward the tubes, a tube plate is fixed to an opening peripheral portion of the tank, in a state where the tube plate and the opening peripheral portion are overlapped with each other, to form a bottom portion of the tank, and W 1 ⁇ W 2 ⁇ 1.5, where W 1 is a plate thickness of the tank and W 2 is a plate thickness of the tube plate.
- the tank structure of the heat exchanger in which the end portions of the plurality of tubes are inserted in and fixed to the bottom portion of the tank that is made of aluminum material, has the bead that is provided at the position of the tube side heading from the half position of the height of the side wall portion of the tank to extend in the direction perpendicular to the longitudinal direction of the tubes. Therefore, the tank can be prevented from being deformed due to thermal shock generated when the tubes of the heat exchanger thermally expand and contract. In addition, a flow amount of flowing medium in the tank can be uniformed.
- the tank structure of the heat exchanger in which the end portions of the plurality of tubes are inserted in and fixed to the bottom portion of the tank that is made of aluminum material, has the tank that is formed like the vessel to open toward the tubes.
- the tube plate is fixed to the opening peripheral portion of the tank, in the state where the tube plate and the opening peripheral portion are overlapped with each other, to form the bottom portion of the tank, and W 1 ⁇ W 2 ⁇ 1.5, where W 1 is the plate thickness of the tank and W 2 is the plate thickness of the tube plate.

- FIG. 1 is a rear view showing a tank structure of a heat exchanger of the first embodiment according to the present invention
- FIG. 2 is a cross sectional view taken along a line S 2 -S 2 in FIG. 1
- FIG. 3 is a perspective cross sectional view of the same.
- a heat exchanger 1 of the first embodiment includes a core part 2 , and a pair of tanks 3 and 4 that are arranged above and below the core part 2 , respectively.
- the core part 2 is composed of a pair of tube plates 5 and 6 , a plurality of tubes 8 and a plurality of corrugated fins 9 , where the tube plates 5 and 6 are formed like a tray to each open in a direction opposite to a tube 8 side, the tubes 8 have both end portions that are inserted into and fixed to burring holes 7 , shown in FIG. 2 , of the corresponding tube plates 5 and 6 , and the corrugated fins 9 are disposed between the adjacent tubes 8 .
- both end portions of the tube plates 5 and 6 are connected with each other to add to the strength thereof through a pair of reinforcement members R 1 and R 2 , respectively.
- both of the tanks 3 and 4 are formed like a vessel to open toward the tube 8 side, and opening peripheral portions thereof are stuck up and joined with inner sides of outer peripheral wall portions 10 of the corresponding tube plates 5 and 6 , respectively, to be formed like a box, so that the tanks 3 and 4 are provided with bottom portions, respectively.
- beads 12 a are provided to extend in a direction perpendicular to the longitudinal direction of the tubes 8 in a state where the beads 12 a sink toward an interior of the tank 3 ( 4 ). This considerably increases the rigidity of the tank 3 ( 4 ) in a height direction thereof.
- the dimensions of the depth A 1 and the height A 2 of the beads 12 a may be set appropriately. Further, the beads 12 a are formed in the state where they sink inwardly from the side wall portions 11 a and 11 b of the tank 3 ( 4 ) in the first embodiment, while they may be formed to project outwardly therefrom.
- beads 12 b similar to the beads 12 a are formed above the beads 12 a , which further increases the rigidity of the tank 3 ( 4 ).
- the plate thickness of the tank 3 ( 4 ) of the first embodiment is set to be 1.8 mm, and the plate thickness of the tube plate 5 ( 6 ) is set to be 1.0 mm.
- the tank 3 is provided with an inlet port 13 that projects rearward in a state where it is fluidically communicated with the interior of the tank 3 .
- the tank 4 is provided with an outlet port 14 in a state where it is fluidically communicated with the interior of the tank 4 .
- each tank 3 , 4 is provided at its both end portions with vehicle mounting pins P 1 that projects in a vertical direction.
- all of construction parts thereof are made of aluminum material, and at least one sides of joining portions of the construction parts are provided with a clad layer (a brazing sheet) of brazing filler material.
- the construction parts are heat-treated in a not-shown heat furnace to be integrally joined in a state where they are temporally assembled with each other.
- the thus-constructed heat exchanger 1 is installed on a motor vehicle in a state where the vehicle mounting pins P 1 are fixed on a not-shown radiator core support through mount members that are made of elastic material.
- the inlet port 13 and the outlet port 14 are connected with connecting pipes of a not-shown engine side.
- the high-temperature flowing medium which flows in the tank 3 through the inlet port 13 from the engine side, is cooled down due to heat transfer by air flow generated when the motor vehicle is running or air flow generated by a not-shown electric motor fan, while the flow medium flows through the core part 2 . Then it flows in the tank 4 , and it is discharged toward the engine through the outlet port 14 .
- the heat exchanger 1 functions as a radiator.
- the tanks could have been deformed to expand due to the thermal shock that is generated when each tubes of the heat exchanger thermally expands and contracts in the longitudinal direction thereof. This does not allow the tubes to be formed thin, and as a result the improvement in coolability of the heat exchanger cannot be realized.
- the beads 12 a are formed near bottom portions of the side wall portions 11 a and 11 b of the tanks 3 and 4 to extend in the direction perpendicular to the longitudinal direction of the tubes 8 as described above, so that they can especially reinforce peripheral portions of the bottom portions of the tanks 3 and 4 , thereby preventing the tanks 3 and 4 from being deformed due to the thermal shock that is generated when the tubes 8 expand and contract in the longitudinal direction.
- the tubes 8 can be formed thin, thereby improving the coolability of the heat exchanger 1 .
- the plate thickness of the tank 3 ( 4 ) is set to be equal to or larger than that of the tube plate 5 ( 6 ), so that the stress concentration at the tank 3 ( 4 ) can be decreased by absorbing and dispersing the thermal shock mainly by the tube plate 5 ( 6 ). Therefore, the durability thereof can be improved.
- the opening peripheral portions of the tanks 3 and 4 are joined with the inner side of the outer peripheral wall portions 10 of the tube plates 5 and 6 , respectively, in the state where they are overlapped with each other, so that the rigidity of these joined portions can be considerably and desirably increased.
- experiment results show that desired effect can be obtained in a case where the beads 12 a are provided within an area H 2 of the tube 8 side heading from a half position of the height H 1 of the side wall portions 11 a and 11 b of the tank 3 ( 4 ).
- the bottom portions of the tanks 3 and 4 consist of the tube plates 5 and 6 , respectively, and accordingly the height H 1 of the wall portion of the tank includes the height (the plate thickness) of the tube plate 5 , 6 .
- the height H 1 of the side wall portions of the tank accurately means the height from a tank-side root portion of the tube 8 to upper wall portions of the tank, and it is preferable that the beads 12 a be set nearer the tube 8 side of the tank.
- the beads 12 a are formed and the plate thicknesses are set to satisfy the relationship of W 1 ⁇ W 2 ⁇ 1.5, where W 1 is the plate thickness of the tank 3 ( 4 ) and W 2 is the plate thickness of the tube plate 5 ( 6 ). Nevertheless, according to configurations of the tanks and requested specifications of thermal shock, the plate thicknesses may be set to satisfy W 1 ⁇ W 2 ⁇ 1.5, and no bead may be provided on the tank. On the other hand, only a bead may be provided without satisfying the above relationship, or they may be constructed like the first embodiment.
- the conventional inventions have a problem in that a flow amount of flowing medium flowing through the tubes cannot be uniformed because a flow distribution thereof in the tank 3 tends to incline toward a vicinity of the inlet outlet port 13 .
- the flowing medium which flows in the tank 3 through the inlet port 13 , can be easily flow in the longitudinal direction in the tank 3 along the beads 12 a and 12 b . Therefore, the flowing medium can uniformly flow in the tubes 8 from the tank 3 , thereby further improving the coolability of the heat exchanger 1 .
- the tank 4 is also formed with the beads 12 a and 12 b , and accordingly it can obtain the effects similar to those of the tank 3 . There is no possibility of the increase in flow resistance.
- the tank structure of the heat exchanger 1 in which the end portions of the plurality of tubes 8 are inserted into and fixed to the tube plates 5 and 6 of the tanks 3 and 4 that are made of the aluminum material, has the beads 12 a that extend in the direction perpendicular to the longitudinal direction of the tubes 8 , being arranged at the position of the tube 8 side heading from the half position of the height H 1 of the side wall portions 11 a and 11 b of the tank 3 ( 4 ). Therefore, the tank 3 ( 4 ) can be prevented from being deformed due to the thermal shock that is generated when the tubes 8 of the heat exchanger 1 thermally expand and contract in the longitudinal direction thereof, and the flow amount of the flowing medium in the tank 3 can be uniformed.
- the tank 3 ( 4 ) is formed like the vessel, and its opening peripheral portion are joined with the tube pate 5 ( 6 ), in the state where they are overlapped with each other to be formed like the box, so that the bottom portion of the tank 3 ( 4 ) can be formed.
- the plate thicknesses are set to satisfy the relationship of W 1 ⁇ W 2 ⁇ 1.5, where W 1 is the plate thickness of the tank 3 ( 4 ) and W 2 is the plate thickness of the tube plate 5 ( 6 ). Therefore, it can allow the tubes 8 to thermally expand and contract in the longitudinal direction, ensuring necessary rigidity of the tank 3 ( 4 ).
- FIG. 4 is a cross sectional view illustrating a tank structure of a heat exchanger of the second embodiment.
- a tube plate 20 that is formed like a tray to open toward a tube 8 side is employed instead of the tube plate 5 ( 6 ) that is formed like the first embodiment.
- the tube plate 20 is press-fitted in an opening peripheral portion 23 of a tank 3 ( 4 ), and they are joined with each other by brazing in a state where they are overlapped with each other.
- an opening peripheral portion 21 and a part 22 of seat surfaces, for the tubes 8 , of the tube plate 20 are fixed by brazing with a skirt-like shaped portion 25 that has a cross section like an L-letter shape formed by the opening peripheral portion 23 of the tank 3 ( 4 ) and a part 24 of beads 12 a , in a state where they are surface-contacted with the skirt-like shaped portion 25 , when the tube plate 20 are press-fitted in the tank 3 ( 4 ).
- the second embodiment can obtain the following effects in addition to those of the first embodiment.
- Contact areas of the tubes 8 and the tank 3 ( 4 ) can be increased, thereby being well brazed with each other and increasing the rigidity of their peripheral portions.
- the tube plate 20 and the tank 3 ( 4 ) can be positioned relative to each other by contacting the part 22 of the seat surfaces of the tubes 8 with the part 24 of the bead 12 when the tube plate 20 is press-fitted in the tank 3 ( 4 ). Therefore, they can be brazed with each other, being assembled with high accuracy.
- FIG. 5 is a cross sectional view illustrating a tank structure of a heat exchanger of the third embodiment.
- the beads 12 a and 12 b which are explained in the first embodiment, are removed, and it employs a tank 50 , which is shaped like a vessel to open toward tubes 8 .
- a tube plate 20 and a skirt-like shaped portion 31 are fixed with each other by brazing in a state where the tube plate 20 is press-fitted in an inner side of the skirt-like shaped portion 31 , where the tube plate 20 is constructed as explained in the second embodiment, and the skirt-like shaped portion 31 has a cross section formed like an L-letter shape and is formed around an opening peripheral portion thereof.
- the opening peripheral portion 21 of the tube plate 20 and a part of seat surfaces of the tubes 8 are fixed with the skirt-like shaped portion 31 of the tank 3 ( 4 ) by brazing in a state where they are surface-contacted with the inner side of the skirt-like portion 31 , when the tube plate 20 is press-fitted in the tank 3 ( 4 ).
- the tube plate 20 and the tank 3 ( 4 ) can be well brazed due to the increase in the contact area thereof, thereby obtaining necessary rigidity of the peripheral portions.
- the heat exchanger employs the radiator in the embodiments, while it may employ a general heat exchanger such as an intercooler.
- FIG. 6 it may employ a tank 41 that has a cross section shaped like a U-letter to open in a front and back direction of a motor vehicle, its opening portion being closed up by a lid plate 40 .
- a bead 42 which is formed similarly to the first embodiment, may be provided on a portion near a bottom portion of a tank 41 on one side wall portion 41 of side the wall portions 41 a and 41 b of the tank 41 , and a portion near a bottom portion of the other side wall portion 41 b thereof may be overlapped with the lid plate 40 , in order to increase the rigidity of a peripheral portion near the bottom portion of the tank 41 .
