Description

【Technical Field】 【0001】 The present invention relates to a radiator device. 【Background Art】 【0002】 Patent Document 1 below discloses a radiator device provided at the front part of a vehicle body. This radiator device includes a radiator located behind the front cross member in the vehicle longitudinal direction, and a radiator seal that contacts the rear surface of a front bumper provided at the front end of the vehicle and a part of which is located in front of the front cross member in the vehicle longitudinal direction. 【0003】 The radiator device may include a radiator protector located between the front cross member and the radiator. For example, when a stone on the road surface bounced up by a vehicle passes through the front bumper opening and enters the front space of the vehicle, the radiator protector prevents the stone from colliding with the radiator. 【Prior Art Documents】 【Patent Documents】 【0004】 【Patent Document 1】 Japanese Patent Application Laid-Open No. 2022-93078 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0005】 For example, when the front bumper of a vehicle collides with an obstacle, an external force applied to the front bumper may reach from the radiator seal to the radiator protector and further from the radiator protector to the radiator. 【0006】 In consideration of the above fact, an object of the present invention is to obtain a radiator device in which it is difficult for a force to reach from the radiator protector to the radiator when the front bumper provided at the front end of the vehicle collides with an obstacle. 【Means for Solving the Problems】 【0007】 The radiator device according to claim 1 includes a radiator located behind a front cross member provided on the vehicle in the longitudinal direction of the vehicle, and a device provided between the front cross member and the radiator. The radiator has a core portion which is the heat exchange part of the radiator, a slit-forming portion which faces the core portion in the vehicle's longitudinal direction and has multiple slits, and a side edge portion which is integrated with the slit-forming portion and is located on the outer circumference side of the slit-forming portion when viewed in the vehicle's longitudinal direction. The radiator protector is located between the front bumper and the front cross member, which are provided at the front end of the vehicle, and the radiator protector The aforementioned A radiator seal is provided with an airflow blocking portion on its side that faces the side edge while forming a gap with it, is located outside the side edge in the vehicle width direction, and protrudes toward the rear, It is equipped with. 【0008】 The radiator device according to claim 1 comprises a radiator located behind the front cross member, a radiator protector provided between the front cross member and the radiator, and a radiator seal located between the front bumper and the front cross member. Furthermore, an airflow blocking portion is provided on the side of the radiator seal, facing the side edge of the radiator protector while forming a gap with it. As a result, the flow of hot air behind the radiator from the side of the radiator device towards the front of the radiator is suppressed by the side edge of the radiator protector and the airflow blocking portion of the radiator seal. 【0009】 Incidentally, when a vehicle's front bumper collides with an obstacle, the external force applied to the front bumper is transmitted to the radiator seal, causing it to move backward. However, because the airflow blocking section is located outside the side edge of the radiator protector in the vehicle width direction, even if the radiator seal moves backward, it is unlikely that the airflow blocking section will push the side edge of the radiator protector backward. Therefore, it is unlikely that the radiator protector will move backward and exert force on the radiator. 【0010】 The radiator device of claim 2, in the case of claim 1, comprises a left side portion, a right side portion, an intermediate connecting portion located directly in front of the front cross member and connecting the left side portion and the right side portion, and a cushion mounting portion located directly in front of the side edge portion of the radiator protector and having a cushioning material fixed to its rear surface that contacts the front surface of the front cross member, wherein the distance in the longitudinal direction of the vehicle between the side edge portion and the cushion mounting portion is longer than the distance in the longitudinal direction of the vehicle between the front cross member and the intermediate connecting portion. 【0011】 The radiator seal of the radiator device according to claim 2 comprises an intermediate connection portion located directly in front of the front cross member, and a cushion mounting portion located directly in front of the side edge of the radiator protector, with a cushioning material fixed to its rear surface that contacts the rear surface of the front cross member. Furthermore, the distance between the side edge and the cushion mounting portion in the vehicle longitudinal direction is longer than the distance between the front cross member and the intermediate connection portion in the vehicle longitudinal direction. Therefore, when the radiator seal moves backward due to the front bumper colliding with an obstacle, the intermediate connection portion contacts the front cross member before the cushion mounting portion contacts the side edge of the radiator protector. As a result, the external force acting on the radiator seal is absorbed by the front cross member. Therefore, it is unlikely that the cushion mounting portion will push the side edge of the radiator protector backward, causing the radiator protector to move backward and exert force on the radiator. 【0012】 The radiator device according to claim 3 is the radiator seal according to claim 2, comprising a first supported portion supported by the radiator protector below the intermediate connection portion, and a second supported portion supported by the radiator protector above the intermediate connection portion. 【0013】 In the radiator device of claim 3, the radiator seal comprises a first supported portion supported by the radiator protector below the intermediate connection portion, and a second supported portion supported by the radiator protector above the intermediate connection portion. Therefore, when the intermediate connection portion comes into contact with the front cross member due to the front bumper colliding with an obstacle, a rotational moment with the intermediate connection portion as the center of rotation is likely to be applied to at least one of the first supported portion and the second supported portion. As a result, the energy generated in the vehicle by the collision is absorbed by the destruction of at least one of the first supported portion and the second supported portion. Therefore, the external force applied to the front bumper is less likely to be transmitted to the radiator. [Effects of the Invention] 【0014】 As described above, the radiator device according to the present invention has the excellent effect of making it difficult for force to be applied from the radiator protector to the radiator when the front bumper, which is provided at the front end of the vehicle, collides with an obstacle. [Brief explanation of the drawing] 【0015】 [Figure 1] This is a perspective view of the front of a vehicle equipped with a radiator device according to the embodiment, as seen from the front.

[Figure 9] It is a cross-sectional view taken along the 9-9 arrow line in FIG. 8. 【Embodiments for Carrying out the Invention】 【0016】 Hereinafter, an embodiment of a radiator device 80 according to the present invention will be described with reference to the accompanying drawings. An arrow FR appropriately shown in the drawings indicates the front side in the vehicle longitudinal direction, an arrow LH indicates the left side in the vehicle lateral direction, and an arrow UP indicates the upper side in the vehicle vertical direction. 【0017】 As shown in FIG. 1, a resin front bumper 14 (hereinafter referred to as bumper 14) is fixed to the front end portion of a vehicle body 12 of a vehicle 10. The planar shape of the bumper 14 is a substantially arc shape substantially parallel to the lateral direction. A bumper (grill) opening 16 is provided in the bumper 14. 【0018】 An engine compartment 20, which is a space located immediately behind the bumper 14, is provided in the front portion of the vehicle body 12. A metal front cross member 22, which is located in the engine compartment 20 and behind the bumper 14, is provided in the front portion of the vehicle body 12. The front cross member 22 extends in the lateral direction, and both left and right end portions thereof are fixed to left and right side members (not shown). The cross-sectional shape when the front cross member 22 is cut along a cross section orthogonal to the lateral direction is the shape shown in FIG. 5. As is clear from FIG. 5, the cross-sectional shape of the front cross member 22 is not a linear shape extending in the vertical direction, but a curved shape having a width in the longitudinal direction. Therefore, the rigidity of the front cross member 22 is higher than that in the case where the cross section is a linear shape extending in the vertical direction. 【0019】 A radiator support lower (not shown) is provided at the lower end portion of the front portion of the vehicle body 12. Further, the vehicle 10 includes a drive source and a fan (not shown) provided behind the radiator support lower. The drive source is at least one of an internal combustion engine and an electric motor. The fan is located immediately in front of the drive source. 【0020】 A roughly rectangular radiator 25, as shown in Figures 1 and 2, is mounted on the upper surface of the radiator support lower. A fan is located immediately behind the radiator 25. As shown in Figure 2, the radiator 25 comprises a core section 26, a lower tank 27, and an upper tank 28. The core section 26 performs heat exchange between the high-temperature coolant flowing inside the radiator 25 and the low-temperature air (mainly the airflow from driving or the fan). The high-temperature coolant sent from the power source to the radiator 25 is cooled as it passes through the core section 26. The coolant flowing inside the power source is supplied to the lower tank 27 via piping 35 (see Figure 2) which connects the power source and the lower tank 27 and has an electric pump (not shown), and is supplied from the lower tank 27 to the core section 26. Furthermore, the coolant that has passed through the core section 26 is returned to the power source via the upper tank 28 and piping 36 (see Figure 2) provided in the upper tank 28. 【0021】 As shown in Figure 2, the front of the lower tank 27 is provided with a pair of left and right lower protrusions 29, and each lower protrusion 29 is provided with a support hole 30 that penetrates the lower protrusion 29 in the vertical direction. Furthermore, the front surface of the upper tank 28 is provided with a pair of left and right locking members 31. Each locking member 31 comprises a pair of elastically deformable left and right elastic pieces 32 and a locking claw 33 provided at the front end of each elastic piece 32. 【0022】 Vehicle 10 is equipped with a radiator protector 38, which is a one-piece molded resin part as shown in Figure 2. The front shape of the radiator protector 38 is substantially the same as that of the radiator 25. The lower end of the radiator protector 38 is provided with a pair of left and right projections 39 that extend downward. The upper end of the radiator protector 38 is provided with a pair of left and right locking holes 40. Furthermore, the parts of the radiator protector 38 other than the upper and lower ends are provided with numerous slits 38A that penetrate the radiator protector 38 in the front-rear direction. In addition, the left and right sides of the radiator protector 38 are provided with lateral projections 41, which have a curved shape that protrudes forward. 【0023】 As shown in Figures 2 and 7, side walls 42A are provided on the left and right sides of the radiator protector 38 above the lateral projections 41, and side walls (side edges) 43A are provided on the parts below the lateral projections 41. Side walls 42A and 43A are flat plate-shaped parts perpendicular to the left-right direction. Furthermore, as shown in Figures 2 and 7, an upper flange (side edge) 42B projecting to the left is provided on the rear edge of the left side wall 42A, and an upper flange 42B projecting to the right is provided on the front edge of the right side wall 42A. The upper flange 42B is a flat plate-shaped part perpendicular to the front-rear direction. Furthermore, as shown in Figures 2, 8 and 9, a lower flange 43B projecting to the left is provided on the rear edge of the left side wall 43A. Although not shown, a lower flange 43B projecting to the right is provided on the front edge of the right side wall 43A. The lower flange 43B is a flat plate-shaped portion perpendicular to the front-rear direction. Furthermore, lower locking portions 44 are provided at the lower part of both the left and right sides of the radiator protector 38, and a pair of upper locking portions 46 are provided at the upper end of the radiator protector 38. Locking holes 45 are provided in the lower locking portions 44, and locking holes 47 are provided in the upper locking portions 46. 【0024】 A first cushioning material 48 made of urethane, whose side shape is substantially the same as that of the lateral protrusions 41 on both sides of the radiator protector 38, is fixed to the front of the lateral protrusions 41 on both sides. 【0025】 The left and right projections 39 of the radiator protector 38 are inserted from above into the left and right support holes 30 of the radiator 25, and the left and right locking members 31 of the radiator 25 are press-fitted into the left and right locking holes 40 of the radiator protector 38. That is, each locking member 31 is inserted into the corresponding locking hole 40 with the pair of elastic pieces 32 elastically deformed in a direction that brings them closer together, and each locking claw 33 faces the front surface of the upper end of the radiator protector 38. In this way, the radiator protector 38 is attached to the radiator 25 using the support holes 30, locking members 31, projections 39 and locking holes 40. The radiator protector 38 is located directly in front of the radiator 25, and each slit 38A faces the core portion 26 in the front-rear direction. The lower end of the radiator 25, which is integrated with the radiator protector 38, is fixed to the upper surface of the radiator support lower. As a result, as shown in Figures 1 and 4, the radiator 25 and radiator protector 38 are positioned directly behind the front cross member 22, and the left and right first cushioning materials 48 contact the rear surface of the front cross member 22 while elastically deforming. 【0026】 Vehicle 10 is equipped with a radiator seal 50 which is a one-piece molded resin product as shown in Figures 2 to 5. The radiator seal 50 comprises a main body portion 51 which is a frame with a substantially rectangular front shape, an upper airflow blocking portion (airflow blocking portion) 57, a cushion mounting portion 58, a lower airflow blocking portion (airflow blocking portion) 59, an intermediate connecting portion 60, a lower locking member (first supported portion) 61, and an upper locking member (second supported portion) 65. The main body portion 51 comprises a left side portion 52 extending in the vertical direction, a right side portion 53 extending in the vertical direction, an upper side portion 54 which connects the upper ends of the left side portion 52 and the right side portion 53 and extends in the left-right direction, and a lower side portion 55 which connects the lower ends of the left side portion 52 and the right side portion 53 and extends in the left-right direction. The upper part of the left side portion 52 and the right side portion 53 is provided with an upper airflow blocking portion 57 which protrudes toward the rear. Furthermore, cushion mounting portions 58 are provided at the upper rear edges of the left side portion 52 and the right side portion 53, projecting inward in the vehicle width direction. The side shape of the cushion mounting portion 58 is a curved shape that projects forward. Lower airflow blocking portions 59 are provided at the lower parts of the left side portion 52 and the right side portion 53, projecting rearward. As shown in Figures 8 and 9, the rear end portion 59A of the lower airflow blocking portion 59 is composed of a plate-like portion that is substantially perpendicular to the front-rear direction. 【0027】 Furthermore, both ends of the intermediate connecting portion 60, which extends in the left-right direction, are connected to the vertically intermediate portions of the left side 52 and the right side 53. The cross-sectional shape of the intermediate connecting portion 60 when cut at a cross section perpendicular to the left-right direction is the shape shown in Figure 5. As is clear from Figure 5, the cross-sectional shape of the intermediate connecting portion 60 is not a straight shape extending in the vertical direction, but a curved shape with width in the front-rear direction. The cross-sectional shape of the intermediate connecting portion 60 is almost identical to the cross-sectional shape of the front cross member 22. Therefore, the rigidity of the intermediate connecting portion 60 is higher than in the case where the cross section is a straight shape extending in the vertical direction. 【0028】 As shown in Figures 2 and 8, lower locking members 61 are provided at the lower part of the left side 52 and the right side 53. Each lower locking member 61 comprises a pair of elastically deformable upper and lower elastic pieces 62 and a locking claw 63 provided at the front end of each elastic piece 62. Furthermore, a pair of left and right upper locking members 65 are provided on the rear surface of the upper side 54. Each upper locking member 65 comprises a pair of elastically deformable left and right elastic pieces 66 and a locking claw 67 provided at the front end of each elastic piece 66. 【0029】 As shown in Figure 2, a second cushion member 69 made of urethane, having a roughly U-shaped front surface, is fixed to the front surfaces of the left side 52, the right side 53, and the upper side 54. Furthermore, a third cushion member (cushioning material) 70 made of urethane, having a side surface shape substantially identical to that of the cushion mounting portion 58, is fixed to the rear surfaces of the left and right cushion mounting portions 58. 【0030】 As shown in Figure 1, the main body 51 of the radiator seal 50, which is integrated with the second cushion member 69 and the third cushion member 70, is positioned between the bumper 14 and the front cross member 22 such that the intermediate connection portion 60 is located directly in front of the front cross member 22. Furthermore, the left and right lower locking members 61 are press-fitted from the front into the locking holes 45 of the left and right lower locking portions 44 of the radiator protector 38. That is, as shown in Figure 8, each lower locking member 61 is inserted into the corresponding locking hole 45 with the pair of elastic pieces 62 elastically deformed in a direction that brings them closer together, and each locking claw 63 faces the rear surface of the lower locking portion 44. Furthermore, the left and right upper locking members 65 are press-fitted forward into the locking holes 47 of the left and right upper locking portions 46 of the radiator protector 38. That is, with the pair of elastic pieces 66 elastically deformed in a direction that brings them closer together, each upper locking member 65 is inserted into the corresponding locking hole 47, and each locking claw 67 faces the rear surface of the upper locking portion 46. In this way, the radiator seal 50 is attached to the radiator protector 38 using the lower locking portion 44, the upper locking portion 46, the lower locking member 61, and the upper locking member 65. Furthermore, the left and right third cushion members 70 come into contact with the front surface of the front cross member 22 while elastically deforming. At this time, the rear surface of the intermediate connection portion 60 moves forward from the front cross member 22. Furthermore, the front surface of the second cushion member 69 comes into contact with the rear surface of the bumper 14 while elastically deforming. 【0031】 At this time, as shown in Figures 6 and 7, the left and right upper airflow blocking portions 57 of the radiator seal 50 face each other while forming a small gap with the left and right upper flanges 42B. These small gaps are preferably 1.0 mm or less. More specifically, as shown in Figure 7, the left upper airflow blocking portion 57 is located slightly to the left of the left upper flange 42B, and the right upper airflow blocking portion 57 is located slightly to the right of the right upper flange 42B. 【0032】 At this time, as shown in FIGS. 8 and 9, the rear end portion 59A of the lower airflow blocking portion 59 on the left side of the radiator seal 50 faces the left side wall 43A while forming a minute gap (gap). This minute gap is preferably 1.0 mm or less. More specifically, as shown in FIG. 9, the rear end portion 59A on the left side is located slightly to the left of the left side wall 43A. Further, a gap CL1 in the front-rear direction is formed between the rear end portion 59A on the left side and the lower flange 43B on the left side. This gap CL1 is sufficiently larger than the gap CL2 between the rear end portion 59A on the left side and the left side wall 43A. Although not shown, the rear end portion 59A on the right side is located slightly to the right of the right side wall 43A. That is, the rear end portion 59A on the right side and the right side wall 43A face each other while forming a minute gap (gap). This minute gap is preferably 1.0 mm or less. Further, a gap CL1 in the front-rear direction is formed between the rear end portion 59A on the right side and the lower flange 43B on the right side. This gap CL1 is sufficiently larger than the gap CL2 between the rear end portion 59A on the right side and the right side wall 43A. Further, as shown in FIG. 7, at this time, the front-rear direction distance between the upper flange 42B on the left side and the upper part of the cushion mounting portion 58 is set as L1, and the front-rear direction distance between the upper flange 42B on the right side and the upper part of the cushion mounting portion 58 is set as L2. Also, as shown in FIG. 5, the front-rear direction distance between the rear surface of the intermediate connection portion 60 and the front surface of the front cross member 22 at this time is set as L3. In this case, L3 < L1, L3 < L2, L3 < gap CL1 and L3 < gap CL2. 【0033】 Among the configurations described above, the radiator 25, the radiator protector 38, the first cushion material 48, the radiator seal 50, the second cushion member 69, and the third cushion member 70 are components of the radiator device 80. 【0034】 (Operation and Effect) Next, the operation and effect of the present embodiment will be described. 【0035】 When the drive source operates, the heat generated by the drive source is absorbed by the coolant, and the heated coolant is sent from the drive source to the lower tank 27 via the piping 35. This coolant is supplied from the lower tank 27 to the core section 26. The core section 26 performs heat exchange as this coolant flows from the lower end to the upper end of the core section 26. Therefore, when the vehicle 10 is moving forward, the airflow passing through the bumper opening 16 towards the core section 26 causes the heat generated in the core section 26 to move towards the rear of the radiator 25. Also, when the fan is rotating while the vehicle 10 is stopped, the negative pressure generated by the fan causes the heat generated in the core section 26 to move towards the rear of the radiator 25. Therefore, when the core section 26 performs heat exchange, hot air may accumulate in the rear region of the radiator 25. 【0036】 Some of the hot air in the rear region of the radiator 25 may try to flow forward from both the left and right sides of the radiator device 80 towards the radiator 25. However, in this embodiment, the radiator protector 38 of the radiator device 80 is provided with upper flanges 42B and lower flanges 43B on both the left and right sides, and the radiator seal 50 is provided with upper airflow blocking parts 57 that face the upper flange 42B while forming a small gap, and lower airflow blocking parts 59 that face the side wall 43A while forming a small gap. Furthermore, the first cushioning material 48 contacts the rear surface of the front cross member 22 while elastically deforming, and the third cushioning member 70 contacts the front surface of the front cross member 22 while elastically deforming. Therefore, the high-temperature air located behind the radiator 25 is prevented from flowing forward from both the left and right sides of the radiator device 80 towards the radiator 25 by the upper flange 42B, lower flange 43B, upper airflow blocking section 57, lower airflow blocking section 59, first cushioning material 48, and third cushioning member 70. 【0037】 Incidentally, the bumper 14 of a vehicle 10 traveling at a low speed may collide with an obstacle (for example, another vehicle) located in front of the vehicle 10. In this case, the external force applied to the bumper 14 from the obstacle may reach the radiator seal 50 via the second cushion member 69, causing the radiator seal 50 to move relative to the radiator 25 backward. However, the left upper airflow blocking portion 57 is located to the left of the left upper flange 42B, and the right upper airflow blocking portion 57 is located to the right of the right upper flange 42B. Furthermore, the rear end portion 59A of the left lower airflow blocking portion 59 is located to the left of the left side wall 43A, and the rear end portion 59A of the right lower airflow blocking portion 59 is located to the right of the right side wall 43A. Therefore, even if the radiator seal 50 moves backward relative to the radiator 25, the possibility of the upper airflow blocking portion 57 pushing the upper flange 42B backward and the possibility of the lower airflow blocking portion 59 pushing the side wall 43A backward are low. Therefore, the possibility of the radiator protector 38 moving backward and exerting force on the radiator 25 is low. 【0038】 Furthermore, the longitudinal distance L3 between the rear surface of the intermediate connection portion 60 and the front surface of the front cross member 22 is smaller than the longitudinal distances L1, L2 and gaps CL1, CL2 mentioned above. Therefore, when the radiator seal 50 moves relative to the radiator 25 in a rearward direction, the intermediate connection portion 60 contacts the front cross member 22 before the cushion mounting portion 58 contacts the upper flange 42B and before the rear end portion 59A of the side airflow blocking portion 59 contacts the lower flange 43B. As a result, any external force applied to the radiator seal 50 is absorbed by the highly rigid metal front cross member 22. Therefore, it is unlikely that the radiator protector 38 will move rearward and exert force on the radiator 25 due to the cushion mounting portion 58 pushing the upper flange 42B rearward or the side airflow blocking portion 59 pushing the lower flange 43B rearward. 【0039】 Furthermore, because the cross-sectional shape of the intermediate connection portion 60 is a curved shape with width in the front-to-back direction rather than a straight shape extending in the vertical direction, the rigidity of the intermediate connection portion 60 is high. Therefore, when the intermediate connection portion 60 deforms due to contact with the front cross member 22, a portion of the energy generated in the vehicle 10 by the collision is absorbed. As a result, compared to the case where the cross-sectional shape of the intermediate connection portion 60 is a straight shape extending in the vertical direction, less energy generated in the vehicle 10 by the collision is transmitted to the radiator 25. 【0040】 Furthermore, the radiator seal 50 includes a lower locking member 61 supported by the lower locking portion 44 of the radiator protector 38 below the intermediate connection portion 60, and an upper locking member 65 supported by the upper locking portion 46 above the intermediate connection portion 60. Therefore, when the intermediate connection portion 60 comes into contact with the front cross member 22 due to the bumper 14 of the vehicle 10 colliding with an obstacle, a rotational moment with the intermediate connection portion 60 as the center of rotation is likely to be applied to at least one of the lower locking member 61 and the upper locking member 65. As a result, at least one of the lower locking member 61 and the upper locking member 65 is destroyed, making it easier to absorb the energy generated in the vehicle 10 by the collision. Therefore, this energy is less likely to be transmitted to the radiator 25. 【0041】 Although the radiator device 80 according to the embodiment has been described above, these can be modified as appropriate without departing from the spirit of the present invention. 【0042】 For example, the structure of the supported portion provided on the radiator seal 50 and the structure of the portion supporting the supported portion provided on the radiator protector 38 are not limited to those described above. For example, the radiator protector 38 may have a portion corresponding to a lower projection 29 (support hole 30) instead of a lower locking portion 44 (locking hole 45), and the radiator seal 50 may have a portion corresponding to a projection 39 instead of a lower locking member 61.
