Definitions
- the present invention relates to an intake manifold having an intercooler disposed therein.
- Patent Document 1 discloses a configuration in which a water-cooled intercooler is disposed in a surge tank of a resin intake manifold. As described above, when the intercooler is assembled to the intake manifold, the volume of the entire intake system can be relatively reduced, and the reaction of the supercharger can be improved.
- the cooling water flow path portion through which the cooling water flows becomes watertight with respect to the intake flow path portion through which the intake air flows.
- the bonding strength of the brazed portion of the intercooler is low.
- vibration input to the intercooler may adversely affect the parts where the intercooler coupling strength is low, and when the intercooler is placed in the collector, the intercooler takes in the intake air at locations other than those fixed to the intake manifold. It is desirable to minimize contact with the manifold.
- the amount of change due to heat shrinkage of the resin changes depending on the requirements of the season, weather, shape, thickness, etc.
- variation in the amount of deformation becomes large, so that it is difficult to accurately predict the final shape of the intake manifold.
- the gap generated between the intake manifold and the intercooler is set larger, the amount of intake air flowing into the gap is relatively increased, and the amount of intake air flowing through the intake passage portion in the intercooler is relatively reduced. Therefore, if the gap is set larger than necessary, there is a problem that the cooling performance of the intake air in the intercooler is deteriorated.
- a rib that protrudes toward the inside of the intercooler housing portion is formed on the inner wall surface of the intercooler housing portion in which the intercooler is housed so as not to interfere with the intercooler. It is characterized by that.
- the rigidity of the rib base wall portion is relatively increased, and the variation in the deformation amount of the rib and the rib base wall portion is relatively increased. Can be made smaller.
- the gap between the intercooler and the intercooler housing portion can be set to a relatively small value within a range in which the gap between the intercooler and the tip of the rib does not interfere (contact) with the minimum value. Since the airflow resistance of the intercooler can be relatively increased, the amount of intake air that flows around the intercooler around the intercooler is reduced and the cooling efficiency of the intake air by the intercooler is reduced. Can be suppressed.
- FIG. 1 and 2 are explanatory views schematically showing the overall configuration of an intake manifold 1 according to the present invention.
- FIG. 1 is a front view
- FIG. 2 is a right side view.
- FIG. 3 is an explanatory view schematically showing the intake manifold 1 alone, and is a front view before the intercooler 5 is assembled.
- FIG. 4 is an explanatory diagram showing, in an enlarged manner, a region B surrounded by a dashed line in FIG.
- FIG. 5 is a cross-sectional view taken along the line AA in FIG.
- the intake manifold 1 is applied to an in-line four-cylinder internal combustion engine (not shown) equipped with a supercharger (not shown), and is made of a resin material, as shown in FIGS. 1 and 2.
- the collector section 2 has an elongated rectangular parallelepiped shape along the cylinder row direction (the left-right direction in FIGS. 1, 3, and 5 and the vertical direction in FIG. 2), as shown in FIGS.
- an intake air inlet 2a through which intake air is introduced
- an elongated intake air introduction passage 2b that is located downstream of the intake air introduction port 2a and extends along the cylinder row direction, and downstream of the intake air introduction passage 2b.
- an intercooler accommodating portion 6 in which the water-cooled intercooler 5 is accommodated.
- the intercooler accommodating portion 6 is a substantially rectangular parallelepiped space, and the opening 7 is formed on the outer wall surface of the collector portion 2.
- reference numeral 15 in FIG. 5 denotes a rectifying plate formed integrally with the collector portion 2 so that the intake air in the intake air introduction passage 2b flows into the intercooler housing portion 6 while spreading along the cylinder row direction. It is set to be inclined with respect to the column direction.
- the intercooler 5 is formed by, for example, joining a plurality of metal members by brazing or the like, and exchanges heat between the intake air in the intercooler accommodating portion 6 and flowing in the collector portion 2 with the cooling water.
- the heat exchanger 5a has a substantially rectangular parallelepiped shape, and a rectangular plate-like lid 5b that closes the opening 7 of the intercooler housing 6.
- the intercooler 5 is inserted into the opening 7 of the intercooler accommodating part 6 from the heat exchange part 5a side, and the outer peripheral edge of the lid part 5b is fixed to the collector part 2 by a bolt (not shown) on the outer peripheral side of the opening 7.
- the In addition, 8 in FIG. 1 is a bolt insertion hole into which the bolt is inserted. In a state where the intercooler 5 is fixed to the collector portion 2, airtightness to the outside of the opening 7 is ensured by the annular packing 9 disposed on the outer peripheral side of the opening 7.
- the intercooler accommodating part 6 is constituted by a wall part 10 constituting the collector part 2, and the inner wall surface of the intercooler accommodating part 6 is an inner wall surface of these wall parts 10.
- the intercooler housing 6 is designed so as not to interfere with the intercooler 5 except for a portion fixed to the collector 2, taking into account deformation after molding due to heat shrinkage of the intake manifold 1. It is set in advance to be larger than the heat exchange part 5a.
- the intercooler accommodating portion 6 is an intercooler assembled to the collector portion 2 with respect to the four wall portions 10 a, 10 b, 10 c, and 10 d around the opening 7 and the wall portion 10 e facing the opening 7.
- a predetermined gap is set between each of the five wall parts 10a to 10e and the heat exchanging part 5a of the intercooler 5.
- the intake manifold 1 is made of resin, the amount of change due to heat shrinkage of the resin changes depending on the requirements of the season, weather, shape, thickness, etc., but the heat exchanger 5a of the intercooler housing 6 and the intercooler 5 is changed. Is set so that they do not interfere with each other even when the amount of change due to product variations during production, thermal shrinkage of the resin, or the like is maximized.
- the inner wall surfaces of the wall portions 10a and 10b located on one end side and the other end side in the cylinder row direction are as shown in FIGS.
- a plurality of ribs 11 facing the heat exchanging portion 5a of the intercooler 5 are formed to protrude.
- the tip of the ribs 11 is located at the heat exchanger 5 a of the intercooler 5.
- the interval between the wall surface and the intercooler 5 is set so as not to interfere.
- the rib 11 is a protrusion having a rectangular cross section, and is formed along the direction in which the intercooler 5 is inserted into the opening 7.
- three ribs 11 are formed on the inner wall surface of the wall portion 10a, and four ribs 11 are formed on the inner wall surface of the wall portion 10b.
- FIG. 1 and 2 is an inlet for cooling water supplied to the intercooler 5, and 14 in FIGS. 1 and 2 is an outlet for cooling water discharged from the intercooler 5. is there.
- the cooling water supplied from the cooling water inlet 13 flows through the intercooler 5 toward the other end side in the cylinder row direction (left side in FIG. 1). It turns and flows toward one end side (right side in FIG. 1) in the cylinder row direction, and is discharged from the cooling water discharge port 14.
- the rib 11 root portion of the wall portions 10a and 10b has a relatively high rigidity, and the ribs 11 and the amount of deformation due to heat shrinkage or the like of the base wall portions 10a and 10b of the rib 11 is suppressed as compared with the case where the rib 11 is not formed. That is, the variation in the deformation amount at the tip of the rib 11 is relatively smaller than the variation in the deformation amount of the wall portions 10a and 10b when the rib 11 is not formed.
- the ribs 11 are provided on the wall portions 10a and 10b.
- the gap between the wall surfaces of the wall portions 10a and 10b and the heat exchanging portion 5a of the intercooler 5 can be made relatively small.
- the gap between the heat exchanger 5a of the intercooler 5 and the intercooler container 6 in the intercooler container 6 is changed between the heat exchanger 5a and the tip of the rib 11. Since the gap between the two can be minimized within a range in which they do not interfere (contact) with each other, and the ventilation resistance of the gap can be relatively increased, the intercooler is accommodated in the intercooler housing 6. Therefore, it is possible to reduce the amount of intake air flowing around the branch passage portion 3 on the downstream side, bypassing the heat exchanger 5a, and reducing the cooling efficiency of the intake air by the intercooler 5.
- the rigidity of the rib 11 base part becomes high among wall part 10a, 10b by providing the rib 11, compared with wall part 10a, 10b when not providing the rib 11, the rib 11 and the rib 11 base wall part.
- the amount of deformation due to thermal contraction of 10a and 10b can be easily predicted, and the size management of the gap set between the heat exchanging portion 5a and the wall portions 10a and 10b of the intercooler 5 can be facilitated.
- the ventilation resistance between the wall portions 10a and 10b and the heat exchange portion 5a is increased by providing the ribs 11 on the wall portions 10a and 10b as compared with the case where the ribs 11 are not provided.
- the rib 11 is set so as to block the flow of intake air (see the arrow in FIG. 6) between the wall portion 10a and the heat exchanging portion 5a.
- the airflow resistance between the wall portion 10a and the heat exchange portion 5a can be increased more effectively.
- the ribs 11 are set so as to be orthogonal to the flow of intake air between the wall portion 10a and the heat exchanging portion 5a, and the air flow between the wall portion 10a and the heat exchanging portion 5a. In order to increase the resistance, the rib 11 is more advantageous than the case where the rib 11 is not orthogonal to the flow of intake air between the wall portion 10a and the heat exchange portion 5a.
- the collector section 2 Since the collector section 2 is elongated along the cylinder row direction and the intake inlet 2a is located at one end side in the cylinder row direction, the intake air flowing through the intercooler accommodating portion 6 is sucked into the intake inlet 2a. Due to the inertia of the intake air flow introduced from above, there is a tendency to flow more on the side farther from the intake air inlet 2a (the other end side in the cylinder row direction) than on the side closer to the intake air inlet 2a (one end side in the cylinder row direction). . Therefore, more intake air can easily flow into the gap between the heat exchange part 5a and the wall part 10b of the intercooler 5 than the gap between the heat exchange part 5a and the wall part 10a of the intercooler 5.
- a relatively large number of ribs 11 are set on the wall portion 10b.
- the wall portion 10a that is closer to the intake inlet 2a than the wall portion 10b is easily set to have a relatively thick wall in terms of molding, and dimensional accuracy management during heat shrinkage can be achieved even if the number of ribs 11 is increased. Therefore, also in this respect, when the plurality of ribs 11 are provided on the wall portions 10a and 10b, the number of the ribs 11 provided on the wall portion 10b far from the intake inlet 2a is determined from the intake inlet 2a. It is desirable to increase the number of ribs 11 provided on the wall 10a on the near side.
