Definitions

  • the present invention relates to a protecting structure of a heat exchanger for a motor vehicle.
  • a conventional protecting structure of a heat exchanger for a motor vehicle is disclosed in Japanese Patent Application Laid-Open Publication No. 2000 - 52752 .
  • This conventional protecting structure is provided with a protect member which is arranged in front of a core part having a plurality of tubes and fins, which are arranged alternately with each other, in order to protect the tubes from being attacked by a foreign body such as a rock flying from the outside of the core part.
  • the conventional protecting structure has a problem in that, since the protect member is composed of a plurality of louvers, an attack object, which is flown obliquely upward along an inclined angle of the louvers from a front side of the motor vehicle, might pass through a clearance formed between the louvers and be collided with the tubes.
  • the present invention is made in order to solve the above-described problem, and it object is to provide a protect structure of a heat exchanger for a motor vehicle that can surely protect each tube by avoiding a collision between a core part and an attack object flying to the core part from an oblique front side of the motor vehicle.
  • a protect structure of a heat exchanger for a motor vehicle, including a core part of the heat exchanger and a protect member.
  • the core part has a plurality of tubes and fins that are alternately arranged with each other, and the protect member is provided at a front side of the core part.
  • the protect member has a plurality of protecting portions extending in a longitudinal direction of the tubes to cover front sides of the tubes of the core part and avoid a collision between the core part and an attack object that is flown from an oblique front side of the motor vehicle toward the core part.
  • the core part has the plurality of tubes and fins that are alternately arranged with each other, and the protect member is provided at the front side of the core part.
  • the protect member has the plurality of protecting portions extending in the longitudinal direction of the tubes to cover front sides of the tubes of the core part and avoid the collision between the core part and the attack object that is flown from the oblique front side of the motor vehicle toward the core part. Therefore, the protect structure of the present invention can surely protect the tubes by avoiding the collision between the core part and the attack object that is flown from the oblique front side of the motor vehicle toward the core part.

  • FIG 12 is a view illustrating an operation of the protect structure.
  • the protect structure of the heat exchanger for the motor vehicle of the first embodiment has a protect member 20 that is arranged at a front side of the heat exchanger 1.
  • the heat exchanger 1 is what is called an air-cooled type intercooler which cools a compressed intake air, by airflow generated when the motor vehicle is running and/or airflow generated by a not-shown motor fan, in order to make a sufficient effect on supercharging of the intake air.
  • the heat exchanger 1 is provided with a core part 2, an inlet port 3 and an outlet port 4.
  • the core part 2 includes a plurality of tubes 5 and a plurality of outer fins 6, in which they are alternately arranged with each other.
  • each tube 5 has a pair of shells 7 and 8 and an inner fin 9 which is arranged in the pair of shells 7 and 8, where is formed like a dish to be coupled with each other.
  • two annularly projecting portions 7a are formed at each end portion, in a longitudinal direction of the shells 7 and 8, of the shell 7 to open upward, while two annularly projecting portions 8a are formed at each end portion, in a longitudinal direction of the shells 7 and 8, of the shell 8 to open downward.
  • the inner fin 9 employs what is called an offset fin in which a plurality of column portions 9a are arranged parallel to a longitudinal direction of the tube 5 as shown in FIG 5 , and it is formed with two opening portions 9b so that the opening portions 9b are co-axial with the annularly projecting portions 7a and 7b formed on the shells 7 and 8, respectively.
  • the inner fin 9 is not limited to the offset fin, and it may employ a corrugated fin.
  • a plurality of embossed portions 10, which are hollowed like a hemispherical shape in an inner side of the shells 7 and 8, are formed close to the annularly projecting portions 7a and 8a of the shells 7 and 8, being apart in a forward and rearward direction thereof.
  • the inner fin 9 is positioned by the embossed portions 10 in a state where the inner fin 9 is pressed in the shells 7 and 8 by the embossed portions 10 when the shells 7 and 8 are coupled with each other. Further, as shown in FIG. 4 , an outer diameter W1 of the annularly projecting portion 7a formed on the shell 7 of the tube 5 is set to be smaller than an inner diameter W2 of the annularly projecting portion 8a formed on the shell 8.
  • an inlet passage R1 is formed so that it is fluidically communicated with the inlet port 3and one end portions of the tubes 5, while an outlet passage R2 is formed so that it is fluidically communicated with the outlet port 4 and the other end portions of the tubes 5.
  • the outer fins 6 of the heat exchanger 1 are formed with a plurality of louvers 6a, as shown in FIG 12 , between top portions and bottom portions of corrugated surface thereof, respectively.
  • the louvers 6a are not indispensable in the present invention.
  • All parts, which constitute the heat exchanger 1 having the protect structure of the first embodiment, are made of aluminum. At least one side portions of connecting portions of all the parts are provided with a clad layer, namely a brazing sheet, of brazing material, and then they are temporally assembled to be conveyed into a not-shown heat furnace, where the connecting portions are brazed and integrally fixed to each other. Designs of the parts/portions of the heat exchanger 1 may be appropriately changed in detail configurations, the number thereof, positions where they are to be formed, and others.
  • the protect member 20 is formed of plastic material as one unit to have a plurality of protecting portions 21 and two connecting portions 22 and 23, where the protecting portions 21 have the same length in a longitudinal direction of the core part 2 of the heat exchanger 1 as that of the core part 2, and the connecting portions 22 and 23 connect both end portions of the protecting portions 21 in an upward and downward direction.
  • the protecting portions 21 are installed at positions corresponding to the tubes 5 of the core part 2 of the heat exchanger 1, respectively.
  • the protecting portions 21 are formed to have a cross section formed in an approximately triangular shape, which is converged toward the front side of the motor vehicle to have a tip portion 21 a at the front side thereof as shown in FIG 11 . Due to this shape, an opening length W3, in the upward and downward direction, between the adjacent rear edge portions 21b of the adjacent protecting portions 21 becomes smaller than an opening length W4, in the upward and downward direction, between the adjacent tip portions 21a of the adjacent protecting portions 21.
  • a length (a depth) H of the protecting portion 21 in the forward and rearward direction of the motor vehicle, a height (a length between the rear edge portions) W of a rear surface 21d thereof, and an angle ⁇ of the tip portion 21a may be set appropriately, at least as long as the height W is set to be longer than a length of the tube 5 of the heat exchanger 1 in the upward and downward direction, namely an outer diameter of the tube 5.
  • the connecting portions 22 and 23 are provided on rear surfaces thereof with a plurality of fixing portions 24 (three fixing portions on each connecting portion 22, 23 in this embodiment) which are shaped like a circular cylinder and project rearward from the rear surfaces.
  • the fixing portions 24 are formed with pins 24a and 24b that are formed like a circular cylinder and project from their end portions in the upward direction and the downward direction, respectively.
  • each fixing portion 24 is engaged with the embossed portions 10 of the respective shells 7 and 8 of the heat exchanger 1, so that the protect member 20 is fixed at the front side of the core part 2 of the heat exchanger 1. Accordingly, the embossed portions 10 can press and position the inner fin 9 at the inner side of the embossed portions 10, and at the same time the pins 24a and 24b of the fixing portions 24 of the protect member 20 can be engaged with the respectively corresponding outer sides of the embossed portions 10. In this state, each protecting portions 21 of the protect member 20 covers the respectively corresponding tubes 5, and the respectively corresponding outer fins 6 are arranged between the adjacent rear edge portions 21b of the adjacent protecting portions 21.
  • an intake air which has been compressed by a not-shown supercharger to have a temperature of approximately 160°C, enters the inlet passage R1 through the inlet port 3.
  • the intake air is indicated by dashed lines in FIG. 7 .
  • the intake air is cooled down to approximately 40°C due to heat exchange, between the intake air and the airflow generated when the motor vehicle is running and/or the airflow generated by the motor fan, through the outer fins 6 while it flows through the tubes 5 into the outlet passage R2.
  • This intake air cooled is discharged through the outlet port 4 to an engine.
  • the airflow Z generated when the motor vehicle is running or the airflow Z generated by the motor fan is separated in the upward direction and in the downward direction at the tip portions 21a of the protecting portions 21 to smoothly flow to the respectively corresponding outer fins 6 along adjacent slanted portions 21e of the protecting portions 21.
  • each protecting portions 21 of the protect member 20 can function to smoothly guide the airflow Z to the outer fins 6.
  • the projecting portions 21 can prevent the attack object X, such as a rock flying from the front side of the core part 2, from being collided with the tubes 5, thus avoiding damage and/or a crack in the tubes 5.
  • the protecting portions 21 can surely protect the core part 2, especially the tubes 5 of the core part 2.
  • the attack object X when the attack object X is flow toward the core part 2 at an angle smaller than the certain angle ⁇ 1, in other words at an angle close to a vertical direction, to pass through the clearance formed between the protecting portions 21, the attack object X that is larger than the opening length W3 cannot pass through the clearance, because the opening length W3, between the adjacent rear edge portions 21b of the adjacent protecting portions 21, is set to be smaller than the opening length W4 between the tip portions 21b thereof. This maintains the damage of the core part 2 to the minimum.
  • the attack object X is smaller than the opening length W3, the attack object X is collided with the outer fins 6, thus not causing the damage in the tubes 5.
  • the core part 2 is composed of the plurality of tubes 5 and outer fins which are alternately arranged with each other, and the protect member 20 is provided at the front side of the core part 2.
  • the protect member 20 extends in the longitudinal direction of the tubes 5 in a state where the protect member 20 covers the front sides of the tubes 5 of the core part 2, being provided with the protecting portions 21 for avoiding the collision between the core part 2 and the attack object X that is flown from the oblique front side of the motor vehicle toward the core part 2. Therefore, in the first embodiment, the tubes 5 can be surely protected, by avoiding the collision between the core part 2 and the attack object X flown from the oblique front side of the motor vehicle toward the core part 2.
  • the cross sections of the projecting portions 21 are formed in such a way that the opening length W3, which is formed between the adjacent rear edge portions 21b of the adjacent protecting portions 21, is set to be smaller than the opening length W4 formed between the adjacent front tip portions 21a thereof. Therefore, this can provide an intake air guide function, preventing the attack object X that is larger than the opening length W3 from passing through the clearances formed between the protecting portions 21 to collide with the tubes 5.
  • the projecting portions 21 are formed to have the cross section formed in the approximately triangular shape which is converged toward the front side of the motor vehicle. Therefore, the projecting portions 21 can have the shape suitable for effectively guiding the airflow Z.
  • the inner fins 9 are installed inside the tubes 5 of the heat exchanger 1, and they are positioned by using the embossed portions 10 formed on the tubes 5.
  • the protect member 20 is provided with the fixing portions 24, which are engaged with the embossed portions 10 so that the protect member 20 can be fixed to the heat exchanger of the motor vehicle. Therefore, the embossed portions 10 can be used for positioning the inner fins 9 and also for fixing the protect member 20.
  • a second embodiment according to the present invention will be described.
  • its parts/portions similar to those of the first embodiment are indicated by the same reference numbers as those of the first embodiment, and their explanations will be omitted.
  • Different parts/portions of the second embodiment will be described below in detail.
  • FIG 13 is a cross sectional view showing protecting portions of a protect structure, of a heat exchanger for a motor vehicle, of the second embodiment.
  • each protecting portions 30 is formed to have a cross section formed in an approximately semi-circular shape at a front side of the protecting portions 30, which is different from those of the first embodiment.
  • the second embodiment can obtain the effects similar to those of the first embodiment, and it can save its weight by cutting down excessive material for forming the protecting portions 30.
  • the attack object since there is no pointed portion at the front side of the protecting portions 30, the attack object might be not stuck on the protecting portions 30.
  • the heat exchanger for the motor vehicle is not limited to an intercooler, and it may be applied to all kinds of general heat exchangers for motor vehicles, such as a radiator, a condenser, an integral heat exchanger in which a radiator and a condenser are integrally assembled with each other, and an oil cooler.
  • the cross sectional shapes of the protecting portions are not limited to the approximately triangular shape or the approximately semi-circular shape, and they may be set appropriately.
