JP-A-8-14289

  By the way, when an intercooler having an intercooler core portion whose overall shape is smaller than that of the radiator core portion is attached to the front surface of the radiator, not only the intercooler core portion but the entire intercooler faces the radiator core portion. In such a case, the intercooler has a large thermal effect on the radiator core portion because the portion that is easily heated by the intake air, such as the inlet tank, is disposed at a position close to the radiator core portion. On the other hand, if the intercooler is disposed at a position away from the radiator core, outside air that circulates from the periphery of the intercooler to the rear of the intercooler increases, and the cooling efficiency of the intercooler decreases.

  An object of the present invention is to provide a vehicular cooling device that suppresses the thermal influence of an intercooler on a radiator core and a decrease in cooling efficiency of the intercooler.

  A vehicle cooling device that solves the above problems is a radiator having a radiator core that cools engine coolant, and an intercooler that faces the radiator core at a position away from the radiator, and cools intake air. The intercooler core part is opposed to a part of the radiator core part, the intercooler extends from the peripheral part of the intercooler core part toward the radiator core part, and the intercooler core part and the radiator core. A guide member surrounding a space between the first and second portions.

  According to the said structure, the thermal effect of the intercooler with respect to a radiator core part can be suppressed because an intercooler is located in the position away from the radiator. In addition, since the space between the intercooler core portion and the radiator core portion is surrounded by the guide member, outside air that has passed through the intercooler core portion is guided to the radiator core portion, and the intercooler It is possible to suppress the outside air from flowing around. Thereby, it becomes easy to ensure the amount of outside air that passes through the intercooler, and a decrease in cooling efficiency in the intercooler can be suppressed.

In the vehicular cooling device, the guide member may have a shape extending in a direction perpendicular to the intercooler core portion.
According to the said structure, in a radiator core part, the high temperature area | region which is an area | region where the external air heated up by passing through an intercooler core part flows in can be limited to the area | region where an intercooler core part opposes. Therefore, it is possible to suppress a decrease in the cooling efficiency of the radiator.

  In the vehicular cooling device, the direction in which the cooling pipe extends in the radiator core portion is the first direction, and the second direction orthogonal to the first direction, and the cooling pipes are arranged in the radiator core portion. It is preferable that the direction is the second direction, and the intercooler core portion and the radiator core portion are opposite to each other in the center portion in the second direction.

  The radiator core portion has a high temperature region and a low temperature region in which outside air flows without passing through the intercooler and surrounds the high temperature region. Therefore, the cooling pipe of the radiator core part is divided into a cooling pipe passing through both the high temperature region and the low temperature region and a cooling pipe passing only through the low temperature region. And a mechanical load arises in a radiator core part by the thermal expansion difference which arises between the cooling pipe which passes both a high temperature area | region and a low temperature area | region, and the cooling pipe which passes only a low temperature area | region. According to the said structure, the mechanical load resulting from a thermal expansion difference can be disperse | distributed equally to the low temperature area | region located in the both sides of the high temperature area | region in a 2nd direction. As a result, the thermal effect of the intercooler on the radiator can be suppressed.

In the vehicular cooling device, it is preferable that the guide member has a shape that widens toward a portion closer to the radiator core.
According to the above configuration, since the area of the region surrounded by the guide member is larger in the radiator core portion than in the intercooler core portion, more outside air easily flows into the intercooler. As a result, it is possible to further suppress a decrease in cooling efficiency in the intercooler.

  In the vehicular cooling device, a direction in which the cooling pipe extends in the radiator core portion is a first direction, and a second direction orthogonal to the first direction, and the cooling pipes are arranged in the radiator core portion. The direction is the second direction, and the guide member has a shape that has a constant width in the first direction and widens in the second direction, and extends to both edges of the radiator core portion in the second direction. It is preferable.

  According to the above configuration, since all the cooling pipes constituting the radiator core section pass through both the high temperature region and the low temperature region, even if the outside air heated by passing through the intercooler flows into the radiator core portion, The difference in thermal expansion between the tubes is reduced. Thereby, since the mechanical load which arises in a radiator is suppressed, the thermal influence of the intercooler with respect to a radiator can further be suppressed.

In the vehicular cooling device, it is preferable that the intercooler core portion and the radiator core portion are opposed to each other at center portions in the second direction.
According to the above configuration, since the outside air that passes through the intercooler and flows into the radiator core part is easily dispersed in the second direction, the temperature distribution of the radiator core part in the region surrounded by the guide member can be made uniform. . As a result, the mechanical load generated in the radiator due to the difference in thermal expansion of the cooling pipe in the first direction can be further suppressed.

The lower tank 28 is attached so as to cover the bottom of the radiator core portion 26, and is a portion where the engine coolant that has passed through each first cooling pipe 31 joins.

  In the radiator 25, heat exchange is performed between the first cooling pipe 31 and the engine coolant flowing through the first cooling pipe 31, and the first cooling pipe 31 and the fins 32 are cooled by outside air passing through the radiator core portion 26. As a result, the engine coolant is cooled.

  The radiator brackets 29 and 30 are attached so as to cover each of the side portions of the radiator core portion 26 in the second direction D2. The radiator brackets 29 and 30 fix the radiator 25 to a vehicle body frame (not shown) and also function as a bracket to which the intercooler 35 and the guide member 45 are attached.

  The intercooler 35 includes an intercooler core portion 36 having a rectangular overall shape that is smaller in width in the first direction D1 and in the second direction D2 than the radiator core portion 26, and the intercooler core portion 36 in the second direction D2. An inlet tank 37 and an outlet tank 38 sandwiched between the two. The intercooler 35 is fixed to the radiator 25 by attaching a mounting bracket 39 connected to the inlet tank 37 and the outlet tank 38 to the radiator brackets 29 and 30. At this time, in the intercooler 35, the intercooler core portion 36 is parallel to the radiator core portion 26, and the intercooler core portion 36 has a predetermined interval with respect to a region near the lower tank 28 in the radiator core portion 26. Oppose in the open state. Further, the intercooler 35 is located at a position where the center portions of the intercooler core portion 36 in the second direction D2 face each other so that the position of the intercooler core portion 36 with respect to the radiator core portion 26 does not deviate in the second direction D2 (FIG. 4). In the intercooler 35 having the intercooler core portion 36 whose overall shape is smaller than that of the radiator core portion 26, the whole intercooler core portion 36 faces a part of the radiator core portion 26, and the inlet tank 37 and the outlet tank 38. Each part is opposed to the radiator core part 26 partially or entirely.

  The intercooler core part 36 has a plurality of second cooling pipes 41 extending along the second direction D2 and arranged in the first direction D1. Fins 42 that increase the surface area of the intercooler core portion 36 are formed between the second cooling pipes 41 adjacent to each other in the first direction D1.

  The inlet tank 37 is attached so as to cover one side portion of the intercooler core portion 36 in the second direction D2. The inlet tank 37 is a part where the intake air flowing into the intercooler 35 is distributed to each second cooling pipe 41, and an upstream hose 43 through which the intake air supercharged by the supercharger flows is connected.

  The outlet tank 38 is attached so as to cover the other side portion of the intercooler core portion 36 in the second direction D2. The outlet tank 38 is a portion where the intake air that has passed through the intercooler core 36 joins, and is connected to a downstream hose 44 that sends out the intake air cooled by the intercooler 35 to the engine.

  In the intercooler 35, heat exchange is performed between the second cooling pipe 41 and the intake air flowing through the second cooling pipe 41, and the second cooling pipe 41 and the fins 42 are cooled by outside air passing through the intercooler core portion 36. As a result, the intake air is cooled.

  The guide member 45 is made of metal or resin, guides the outside air that has passed through the intercooler core portion 36 to the radiator core portion 26, and against the space between the intercooler core portion 36 and the radiator core portion 26. The outside air is prevented from flowing from around the intercooler 35. The guide member 45 includes a cylindrical main body 46 that surrounds the space between the intercooler core 36 and the radiator core 26, and a plurality of guide members 45 that extend outward from the main body 46 and are connected to the radiator brackets 29 and 30. Connecting piece 47. The main body 46 includes side walls 46a, 46b, 46c, and 46d, and has a square frame-like cross-sectional shape. The main body portion 46 extends linearly from the peripheral edge portion of the intercooler core portion 36 to a position close to the radiator core portion 26 along the direction perpendicular to the intercooler core portion 36. That is, the main body portion 46 extends toward the radiator core portion 26 in a state where the width between the side walls 46a and 46b and the width between the side walls 46c and 46d are held at a constant width. A gap between the main body portion 46 and the radiator core portion 26 is sealed with a first seal member 48 having a square frame shape made of an elastic body such as sponge. The gap between the main body 46 and the peripheral edge of the intercooler core 36 is sealed with a square frame-shaped second seal member 49 made of an elastic material such as sponge.

  When the vehicle cooling device 20 described above is assembled, first, the radiator 25 is attached to the vehicle body frame. Thereafter, the guide member 45 is attached to the radiator brackets 29 and 30 in a state in which the first seal member 48 is disposed in the gap between the radiator core portion 26 and the main body portion 46 of the guide member 45. The intercooler 35 is attached to the radiator brackets 29 and 30 with the second seal member 49 disposed in the gap between the main body 46 of the guide member 45 and the peripheral edge of the intercooler core 36.

  The space between the radiator 25 and the intercooler 35 has such a size that a condenser of the air conditioner can be disposed. And the connection piece 47 of the guide member 45 is connected with the part in which a capacitor | condenser is connected in a radiator bracket. Therefore, the condenser or the guide member 45 can be disposed in the space between the radiator 25 and the intercooler 35 without changing the structure of the radiator brackets 29 and 30. Moreover, since the holding position of the intercooler 35 with respect to the radiator 25 is not changed, the upstream hose 43 and the downstream hose 44 can be shared.

The operation of the vehicle cooling device 20 will be described with reference to FIG.
In recent years, the intake air flowing into the intercooler 35 tends to increase for the purpose of increasing the engine output and improving the exhaust gas properties, that is, the temperature of the intake air flowing into the intercooler 35 tends to increase.

  In the vehicle cooling device 20, an inlet tank 37 that is heated by supercharged intake air is held at a position away from the radiator core portion 26. Therefore, the thermal influence of the intercooler 35 with respect to the radiator core part 26 can be suppressed.

  Here, as shown in FIG. 3A, in the vehicle cooling device 20 in which the guide member 45 is not provided, the space 50 between the intercooler core portion 36 and the radiator core portion 26 is provided in the intercooler. Outside air tends to flow from around 35. Therefore, the amount of outside air that passes through the intercooler 35 decreases, and the cooling efficiency in the intercooler 35 decreases. On the other hand, in the vehicular cooling device 20 in which the guide member 45 is disposed, the space 50 between the intercooler core portion 36 and the radiator core portion 26 is formed by the guide member 45 as shown in FIG. By being surrounded, outside air can be prevented from flowing into the space 50 from around the intercooler 35. Therefore, the amount of outside air that passes through the intercooler 35 is easily secured, and a decrease in cooling efficiency in the intercooler 35 can be suppressed.

According to the vehicle cooling device 20 of the first embodiment, the effects listed below are obtained.
(1) Since the intercooler 35 is located at a position away from the radiator 25, the thermal influence on the radiator 25 can be suppressed even if the inlet tank 37 is heated by the supercharged intake air. In addition, since the space 50 between the intercooler core portion 36 and the radiator core portion 26 is surrounded by the guide member 45, it is possible to suppress a decrease in cooling efficiency in the intercooler 35.

  (2) A gap between the main body 46 of the guide member 45 and the radiator core 26 is sealed by the first seal member 48. Further, a gap between the main body portion 46 of the guide member 45 and the intercooler core portion 36 is sealed by the second seal member 49. Therefore, it is possible to suppress the outside air from flowing into the space 50 through these gaps. Thereby, the fall of the cooling efficiency in the intercooler 35 can further be suppressed.

  (3) As shown in FIG. 4, the outside air passing through the intercooler core portion 36 is heated by heat exchange in the intercooler core portion 36. Therefore, the radiator core portion 26 is partitioned into a high temperature region 55 into which the outside air that has passed through the intercooler core portion 36 flows and a low temperature region 56 into which the outside air directly flows. The guide member 45 extends from the peripheral edge of the intercooler core 36 along the vertical direction of the intercooler core 36. Therefore, the high temperature area | region 55 is limited to the area | region where the intercooler core part 36 opposes. As a result, since the ratio of the low temperature region 56 in the radiator core portion 26 is increased, a decrease in the cooling efficiency of the radiator 25 can be suppressed.

  (4) Further, as shown in FIG. 4, when comparing the first cooling pipe 31 a passing through only the low temperature region 56 and the first cooling pipe 31 b passing through both the high temperature region 55 and the low temperature region 56, the first cooling pipe 31 b becomes longer than the first cooling pipe 31 a due to thermal expansion in the high temperature region 55. Therefore, a mechanical load due to such a difference in thermal expansion occurs in the radiator core portion 26.

  In this regard, according to the above-described configuration, the intercooler core portion 36 and the radiator core portion 26 are located at positions where the center portions of each other in the second direction D2 face each other. Therefore, the radiator core part 26 can disperse | distribute the mechanical load resulting from the thermal expansion difference mentioned above equally to the low temperature area | region 56a, 56b located in the both sides of the high temperature area | region 55 in the 2nd direction D2. As a result, the thermal influence of the intercooler 35 on the radiator 25 can be further suppressed.

(Second Embodiment)
With reference to FIGS. 5-7, 2nd Embodiment of the cooling device for vehicles is described. The vehicular cooling device of the second embodiment has the same main configuration as the vehicular cooling device of the first embodiment. Therefore, in 2nd Embodiment, a different part from 1st Embodiment is demonstrated in detail, and the detailed description is abbreviate | omitted by attaching | subjecting the same code | symbol about the part similar to 1st Embodiment.

  As shown in FIG. 5, in the second embodiment, the main body 61 of the guide member 60 is composed of side walls 61 a, 61 b, 61 c, 61 d that extend to a position close to the radiator core 26, and has a rectangular frame shape. It has a cross-sectional shape. The width of the main body 61 in the first direction D1 is held by the side walls 61a and 61b at the peripheral edge of the intercooler core 36, and the width in the second direction D2 is set by the side walls 61c and 61d on the radiator core 26 side. It has the shape which is widened as the part located in. The side walls 61c and 61d extend to both edges of the radiator core portion 26 in the second direction D2, and a connecting piece 62 connected to the radiator brackets 29 and 30 is formed at the front end portions thereof. The gap between the main body 61 and the radiator core 26 is sealed by the first seal member 63, and the gap between the main body 61 and the peripheral edge of the intercooler core 36 is a square frame-shaped second seal. Sealed with a member 64.

With reference to FIG. 6 and FIG. 7, the effect | action of the cooling device for vehicles of 2nd Embodiment is demonstrated.
As shown in FIG. 6, the main body 61 of the guide member 60 extends to both edges of the radiator core 26 in the second direction D2. Therefore, the radiator core portion 26 has three regions arranged in the first direction D1, a first low temperature region 65 into which outside air directly flows, a high temperature region 66 into which outside air that has passed through the intercooler 35 flows, and outside air directly flows in. It is partitioned into a second low temperature region 67. As a result, all the first cooling pipes 31 including the first cooling pipes 31 a and 31 b pass through the high temperature region 66, so that thermal expansion in the high temperature region 66 occurs in all the first cooling pipes 31. Thereby, the mechanical load which arises in the radiator core part 26 because the length of the 1st cooling pipe 31 is equalized can be suppressed.

  Further, as shown in FIG. 7, outside air sucked by the fan 21 flows into the intercooler core portion 36 through the high temperature region 66 of the radiator core portion 26. The high temperature region 66 becomes larger than the facing region 55A where the intercooler core portion 36 is opposed because the portion closer to the radiator core portion 26 of the guide member 60 is wider. Therefore, the amount of outside air passing through the high temperature region 66, that is, the amount of outside air flowing into the intercooler core portion 36 increases as the high temperature region 66 increases. In other words, since the portion closer to the radiator core portion 26 of the guide member 60 is wider, the amount of outside air flowing into the intercooler 35 is increased, and a decrease in cooling efficiency of the intercooler 35 can be effectively suppressed.

According to the vehicle cooling device 20 of the second embodiment, the effects listed below are obtained in addition to the effects (1) and (2) described in the first embodiment.
(5) The main body 61 of the guide member 60 has the width in the first direction D1 maintained by the side walls 61a and 61b at the peripheral edge of the intercooler core 36, and the side wall 61c and 61d in the second direction D2. The portion whose width is located on the side of the radiator core portion 26 is wider. Therefore, the area surrounded by the guide member 60 is larger in the radiator core portion 26 than in the intercooler core portion 36. Thereby, more outside air easily flows into the intercooler 35. As a result, a decrease in cooling efficiency in the intercooler 35 can be effectively suppressed.

  (6) In the main body portion 61 of the guide member 60, the side walls 61c and 61d extend to both edges of the radiator core portion 26 in the second direction D2. Therefore, all of the first cooling pipes 31 pass through the high temperature region 66, and the difference in thermal expansion between the first cooling pipes 31 is reduced. Thereby, the mechanical load which arises in the radiator 25 can be suppressed.

  (7) Moreover, the second cooling pipe 41 extends in the second direction D2 orthogonal to the first direction D1 in which the first cooling pipe 31 extends, and is aligned in the first direction D1. Therefore, the width of the intercooler core portion 36 in the first direction D1 can be reduced as compared with the case where the intercooler 35 is installed so that the second cooling pipe 41 extends in the first direction D1. As a result, since the width of the high temperature region 66 in the first direction D1 is reduced, the effect described in the above (6) becomes remarkable.

  (8) The intercooler core portion 36 and the radiator core portion 26 are opposed to each other at the center portions in the second direction D2. Thereby, the outside air that has passed through the intercooler 35 can be efficiently dispersed in the second direction D2, and the inflow amount of outside air per unit area in the high temperature region 66 can be made uniform. As a result, the temperature distribution in the high temperature region 66 is made uniform, so that the mechanical load generated on the radiator 25 due to the difference in thermal expansion of the first cooling pipe 31 can be further suppressed.

In addition, the said embodiment can also be suitably changed and implemented as follows.
The intercooler core portion 36 and the radiator core portion 26 are such that the central portion in the second direction D2 does not face each other, for example, the central portion of the radiator core portion 26 and the central portion of the intercooler core portion 36 are in the second direction. You may oppose in the state which shifted | deviated by D2.

  The second cooling pipe 41 extends in the second direction D2 orthogonal to the first direction D1, which is the extending direction of the first cooling pipe 31. For example, the second cooling pipe 41 may extend in the same direction as the extending direction of the first cooling pipe 31, or in a direction intersecting with the extending direction of the first cooling pipe 31. It may be extended.

  The guide member 60 may have a shape that extends to a position on the inner side of both edges of the radiator core portion 26 in the second direction D2 when the guide member 60 has a shape that widens toward the radiator core portion 26 side. Moreover, the guide member may be widened in the first direction D1, or may be widened in both the first direction D1 and the second direction D2. In any case, an effect similar to the effect of (5) described in the second embodiment can be obtained.

  One or both of the first seal member that seals the gap between the guide member and the radiator core portion and the second seal member that seals the gap between the guide member and the intercooler core portion are omitted. May be.

  The guide member only needs to extend from the peripheral portion of the intercooler core portion 36 toward the radiator core portion 26 and surround the space between the intercooler core portion 36 and the radiator core portion 26. Therefore, the end of the guide member on the side of the radiator core portion 26 may be located not at a position close to the radiator core portion 26 but at a position away from the radiator core portion 26.
