Description

  The present invention relates to a radiator which is a heat exchanger for cooling a vehicle engine cooling medium, and a high temperature compressed by an oil cooler or a supercharger which cools high temperature oil such as transmission oil or power steering oil. The present invention relates to an arrangement structure of a vehicle heat exchanger configured in combination with a heat exchanger such as an intercooler that cools supply air.

  In vehicles using a water-cooled engine as a drive source, in addition to a radiator (hereinafter simply referred to as a radiator) that is a heat exchanger for cooling engine cooling water, for example, transmission oil for an automatic transmission (hereinafter simply referred to as a radiator). Various heat exchangers such as an oil cooler for cooling oil such as AT oil) or power steering oil (hereinafter simply referred to as PS oil), an intercooler for a supercharger, etc. are combined as necessary. It is installed.

  The above-described radiator has an air intake surface larger than the air intake surface of another heat exchanger (hereinafter simply referred to as a heat exchanger) such as the above-described oil cooler or intercooler. In general, a radiator, which is a device, is disposed at the front of the vehicle with its air intake surface facing the front of the vehicle in order to enable efficient air intake.

  The above-described small heat exchanger having an air intake surface smaller than that of the radiator is disposed, for example, in front of the radiator, or disposed between the front bumper fascia and the fender protector in front of the front wheel of the vehicle.

In addition, it is proposed that an intercooler, which is one of the small heat exchangers described above, be disposed outside the side frame member of the vehicle, and the side frame member be used as a cooling air duct for the intercooler. (See Patent Document 1).
Japanese Utility Model Publication No. 6-67145 (page 3-4, FIG. 1)

  However, the engine coolant supplied to the radiator is about 100 ° C., whereas the temperature of the oil supplied to the oil cooler disposed in front of the radiator and the supply air supplied to the intercooler is about 120 ° C. To reach. Therefore, the cooling air that has passed through the heat exchanger that is supplied with a fluid to be cooled that is higher in temperature than the cooling water has a temperature that is higher than or substantially equal to the temperature of the engine cooling water supplied to the radiator.

  Therefore, even if the heat exchanger that receives the supply of the high-temperature fluid to be cooled is smaller than the radiator, the heat exchanger that receives the supply of the high-temperature fluid to be cooled is disposed in front of the radiator. By passing through this heat exchanger, high-temperature air heated to a temperature higher than or substantially equal to the engine coolant temperature flows to the radiator, so that the cooling efficiency of the radiator is significantly reduced. To compensate for this decrease in cooling efficiency, the radiator becomes larger. In addition, since the radiator and the heat exchanger are arranged in parallel in the front-rear direction of the vehicle, there is a risk of increasing the total length of the vehicle at least by the thickness of the heat exchange.

  Therefore, in the conventional technique described in Patent Document 1, the cooling air outlet for the intercooler is formed in the side frame member so that the cooling efficiency of the radiator does not decrease. The collision safety performance of the vehicle deteriorates. Further, the air outlet of the side frame member and the intercooler arranged outside the side frame member are connected by a branch duct, and the installation space in the vehicle width direction is increased by the arrangement of the branch duct. . In addition, since the branch duct is indispensable, the number of parts related to the branch duct increases. In addition, since the intercooler is arranged outside the pair of side frame members, the piping connecting the engine and the intercooler arranged between the side frame members becomes longer, and the cost and weight are accordingly increased. Will increase.

  In view of these points, an object of the present invention is to supply a fluid to be cooled that is higher in temperature than the cooling medium temperature of the radiator without causing an increase in the size of the radiator for cooling the engine cooling medium or a reduction in the strength of the side frame members. An object of the present invention is to provide a vehicle heat exchanger arrangement structure that can realize space saving of the arrangement of the heat exchanger to be received.

  The present invention has an air intake surface disposed toward the front of a vehicle, and is provided with a radiator mounted on the vehicle for cooling an engine cooling medium, and a temperature of the cooling medium supplied to the radiator. And a heat exchanger having an air intake surface for cooling the cooled fluid, the air intake surface of the heat exchanger being arranged along the longitudinal direction of the vehicle. The heat exchanger is arranged on the rear side of the radiator.

  According to the present invention, the heat exchanger is disposed on the rear side portion of the radiator, and the heat exchanger is disposed so that the air intake surface of the heat exchanger is along the front-rear direction of the vehicle. This space can be effectively used as a space for arranging the heat exchanger, so that air having a temperature higher than the cooling medium temperature of the radiator that has passed through the heat exchanger is not blown to the radiator. Reduced cooling efficiency of the radiator can be prevented, the problem of interference with other parts associated with the heat exchanger arrangement can be eliminated, and side frame members can be used as cooling air ducts to the heat exchanger Since it is not necessary, the strength is not reduced by providing the cooling air outlet in the side frame member. Therefore, the conventional problems can be solved and the radiator and the heat exchanger can be properly arranged.

  Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

  FIG. 1 and FIG. 2 are a plan view and a perspective view, respectively, schematically showing a left front half portion of a vehicle according to a first embodiment of the present invention, and an automobile is shown in the illustrated example.

  As shown in FIG. 1, the vehicle 10 according to the present invention includes a pair of front side members 11 (left and right in the drawing) that are disposed along the front-rear direction of the vehicle 10 in the width direction of the vehicle 10. The front side member of the side is shown.) An engine room 12 for mounting an engine (not shown) is formed between the side members 11, and a front bumper facer 13 for shock absorption extending in the width direction of the vehicle 10 is located in front of the side members 11. Is arranged. A conventionally well-known fender protector 14 supported by the side frame member 11 is disposed behind both ends of the front bumper fascia 13 projecting to the side of the front side member 11.

  A radiator 15, which is a heat exchanger for cooling the cooling water of the engine, is disposed in front of the engine room 12 along the front bumper facer 13 and behind the bumper facer. An air intake opening 13 a toward the radiator 15 is formed at a portion corresponding to the radiator 15 of the front bumper fascia 13. A pair of guide plates 16 (one of which is shown in the figure) for guiding the air flow from the air intake opening 13a to the radiator 15 is disposed between the radiator 15 and the front bumper fascia 13. Has been placed.

  As shown in FIG. 2, the radiator 15 includes a radiator core 15 a having a rectangular planar shape, and a pair of tanks 15 b and 15 c that are provided above and below the radiator core and retain cooling water. It is a well-known downflow type radiator. The radiator 15 is disposed along the width direction of the vehicle 10 with the air intake surface 17a facing the front of the vehicle so that the front surface 17a of the radiator core 15a serving as the air intake surface faces the air intake opening 13a. Yes.

  The upper tank 15b and the lower tank 15c of the radiator 15 are respectively connected to a cooling water passage (not shown) formed inside the engine, and as is well known in the art, one of the radiator 15 is connected from the engine. When the cooling water guided to the tank 15b or 15c flows to the other tank 15c or 15b via the radiator core 15a, the cooling water is cooled by heat exchange with the air flow passing from the front surface 17a to the rear surface 17b of the radiator core 15a. Is done. By this cooling, the cooling water heated to, for example, 100 ° C. by the engine is cooled to, for example, 80 ° C. and then returned to the engine from the other tank 15c or 15b. It is properly cooled.

  On the rear surface side of the radiator 15, as shown in FIG. 1, for example, a conventionally well-known cooling fan 18 for increasing the air flow passing through the radiator core 15a during idling operation is disposed. Further, a condenser (condenser) 19 that is a heat exchanger for cooling the refrigerant gas of the air conditioning system is arranged in front of the radiator 15 in parallel with the radiator. The condenser 19 has substantially the same configuration and size as the radiator 15 as is well known in the art. The condenser 19 is connected to a conventionally well-known refrigerant compressor and expansion valve of an air conditioning system (not shown), and the refrigerant heated to, for example, 90 ° C. by being pressurized by the refrigerant compressor is cooled to, for example, about 50 ° C. To do.

  An air-cooled oil cooler 20 for cooling AT oil, which is transmission oil of the automatic transmission, is disposed on the rear surface side of the radiator 15. The oil cooler 20 has a basic configuration similar to that in the radiator 15, and has an air intake surface 21a that is smaller than the air intake surface 17a of the radiator 15 in order to cool transmission oil by the same air cooling action as described above. .

  The oil cooler 20 is disposed on the rear surface of one side of the radiator 15 so as to be close to the left side of the front side member 11 between the pair of front side members 11. Further, the oil cooler 20 is arranged with its air intake surface 21 a directed toward the left front side member 11, that is, toward the left side of the vehicle 10, and the air intake surface 21 a is disposed along the front-rear direction of the vehicle 10. . In the illustrated example, the air intake surface 21 a is substantially perpendicular to the air intake surface 17 a of the radiator 15.

  An air supply duct 22 is provided on the air intake surface 21 a of the oil cooler 20. The air supply duct 22 extends from the air intake surface 21 a of the oil cooler 20 toward the front of the vehicle and opens to an auxiliary air intake port 13 b formed in the front bumper fascia 13. The rear surface 21b of the oil cooler 20 is provided with an exhaust frame 23 that defines an air exhaust port 23a that opens to the inside of the vehicle 10, and the exhaust frame 23 is a reverse for opening and closing the air exhaust port 23a. A stop valve 24 is provided.

  The check valve 24 includes a plate-like valve member 24a having elasticity, and a fixing pin 24b that fixes the valve member to the exhaust frame 23. The fixing pin is positioned on the front side of the vehicle of the valve member 24a. One side to be fixed is fixed to the exhaust frame 23. Due to its elasticity, the valve member 24a is held at a position for closing the air exhaust port 23a as shown by a solid line in FIG. When the wind pressure of the air flow taken from the air intake surface 21a through the air supply duct 22 overcomes the elasticity of the valve member 24a, the valve member 24a is pushed open to the open position indicated by the broken line in FIG. In this open position, the valve member 24a serves to guide the air flow that has passed through the oil cooler 20 from the air exhaust port 23a toward the engine room 12 located on the rear side of the vehicle 10. Further, since the valve member 24a is operated to a closed position where the air exhaust port 23a is closed by the wind pressure generated by the operation of the cooling fan 18 or the wind pressure from the engine room 12, the valve member 24a is directed from the air exhaust port 23a toward the air intake surface 21a. Prevent backflow of airflow.

  The oil cooler 20 in which the air intake surface 21a is arranged along the front-rear direction of the vehicle 10 on the rear side of the radiator 15 receives AT oil from an automatic transmission (not shown), as is well known. Cool AT oil. The AT oil received by the oil cooler 20 reaches about 120 ° C., but this AT oil is cooled by the oil cooler 20 and returned to the automatic transmission.

  In the vehicle 10 according to the present invention, the oil cooler 20 to which the AT oil having a temperature higher than the coolant temperature supplied to the radiator 15 is supplied is the rear side portion of the radiator 15, and the air intake surface 21 a is disposed on the vehicle 10. It is arranged toward the outside, and the high-temperature air that has passed through the oil cooler 20 does not flow to the radiator 15, and the cooling effect of the radiator 15 is not impaired by the high-temperature air that has passed through the oil cooler 20.

  In the illustrated example, the condenser 19 is disposed in front of the radiator 15, but the refrigerant supplied to the condenser 19 is not as high as the temperature of the AT oil supplied to the oil cooler 20, and the radiator 15 Since the temperature is sufficiently lower than the temperature of the supplied cooling water, the cooling effect of the radiator is not greatly impaired to the extent that the radiator 15 needs to be enlarged by the air that has passed through the condenser 19.

  The oil cooler 20 is disposed with its air intake surface 21a facing the outside of the vehicle 10, and in the example shown in the drawing, the cooling air passes through an air supply duct 22 that opens to the front bumper facer 13 on the front surface of the vehicle 10. Since it is taken in from the air intake surface 21a, AT oil can be cooled effectively. Therefore, since it is not necessary to use the front side member 11 as a duct for cooling air, it is not necessary to provide a cooling air outlet in the front side member 11, thereby preventing a decrease in strength of the front side member 11.

  Further, since the cooling air for the oil cooler 20 is guided to the oil cooler 20 via the air supply duct 22, the shape or arrangement of the air supply duct 22 is appropriately selected to assist the opening of the air supply duct. The air intake port 13b can be formed at a position where it does not interfere with a fog lamp (not shown).

  Since the air intake surface 21 a of the oil cooler 20 is disposed toward the outside of the vehicle 10, the air intake surface 21 a can be exposed to the outside air of the vehicle 10 from the outside of the vehicle 10. Even when the oil cooler is not required, it is possible to obtain the AT oil cooling effect by the oil cooler 20. However, in order to enhance the cooling effect of the oil cooler 20, it is desirable to provide an air supply duct 22 as illustrated.

  The air supply duct 22 occupies a part of the space behind the front wheel tire house, but the oil cooler 20 is not disposed between the front bumper fascia 13 and the fender protector 14, and the air supply duct 22 is disposed in the radiator 15. Therefore, the plane camber is limited as much as in the prior art in which the oil cooler is disposed between the front bumper fascia 13 and the fender protector 14 depending on the air supply duct 22. I will not receive it.

  On the other hand, in the above-described conventional technique in which a small heat exchanger is disposed in front of the front wheel, the cooling efficiency of the radiator does not decrease, but the heat exchanger and the heat exchange are between the front bumper fascia and the fender protector. It is necessary to arrange an air guide duct for guiding the cooling air discharged from the cooler to the rear of the tire house, and when trying to give a desired curve to the end shape of the front bumper fascia, the heat exchanger and therefore The front bumper fascia may interfere with the air duct duct. In order to prevent this interference, it is necessary to partially change the shape of the front bumper fascia, and therefore, the bent shape (plane camber) of the front bumper fascia is limited. In addition, an air intake port to the heat exchanger is provided at a position corresponding to the heat exchanger of the front bumper fascia. If this air intake port overlaps with the fog lamp mounting position, the fog lamp cannot be mounted.

  On the other hand, according to the arrangement structure of the heat exchanger according to the present invention, as described above, the auxiliary air intake port 13b where the air supply duct opens can be formed at a position where it does not interfere with the fog lamp. A plane camber is not as limited as in the prior art.

  Further, in the arrangement of the heat exchanger according to the present invention, in addition to the air flow that has passed through the radiator 15, the air flow that has passed through the oil cooler 20 can be directed to the engine room 12 in parallel with this air flow. Thus, the inside of the engine room 12 can be cooled by the air flow, and the ambient temperature of the engine room 12 can be lowered efficiently.

  The check valve 24 provided in the oil cooler 20 reliably prevents hot air from blowing back from the engine room 12 to the oil cooler 20 during the idling operation. When this hot air flows backward through the air supply duct 22 toward the condenser 19 disposed in front of the radiator 15, the refrigerant cooling effect by the condenser is reduced, but the check valve 24 prevents the hot air from blowing back. Thus, the refrigerant cooling effect in the condenser 19 is prevented from being lowered, and the cooling efficiency is thereby prevented from being lowered.

  The cooling fan 18 operates mainly when the vehicle 10 is stopped, such as during idling, and the AT oil cooler 20 cools the AT oil that is the fluid to be cooled when the vehicle 10 travels. Need. As described above, the positive pressure from the cooling fan 18 by the operation of the cooling fan 18 acts on the valve member 24a of the check valve 24 as a force for directing the valve member 24a to the closed position of the air exhaust port 23a. Therefore, it is possible to more reliably prevent the backflow of the hot air through the air supply duct 22 when the vehicle 10 is stopped. On the contrary, when the vehicle 10 is traveling, the cooling fan 18 is in an inoperative state, so that the check valve 24 is surely opened so that the air flow passing through the oil cooler 20 is reliably transmitted to the engine room. 12 can be guided to.

  Further, since the oil cooler 20 is disposed between the pair of side frame members 11, piping to the automatic transmission of the engine disposed in the engine room 12 between the side frame members 11 is connected to the side frame. Compared with the case where it is arranged outside the member 11, it can be shortened, and accordingly, cost reduction and weight reduction can be achieved.

  As shown in FIG. 3 and FIG. 4, the same guiding action as that of the guide plate 16 shown in FIG. 1 can be carried on one side 22 a of the air supply duct 22 located on the vehicle center side. In this case, as shown in FIG. 4, one side 22 a of the air supply duct 22 is disposed close to one side of the radiator 15, and the one side 22 a extends upward along one side of the radiator 15. The extending portion 22b is integrally formed. Thereby, one of the pair of guide plates 16 can be made unnecessary, cost and weight can be reduced, and arrangement space can be reduced.

  Instead of the radiator 15 provided with a pair of tanks 15b and 15c above and below the radiator core 15a, as shown in FIGS. 5 and 6, a pair of side tanks 15d (one of which is shown in the figure) is provided on both sides of the radiator core 15a. So-called cross-flow type radiators can be used. In the cross flow type radiator 15, the oil cooler 20 can be attached to the rear surface of the one side tank 15d located on the vehicle rear side. By attaching the oil cooler 20 to the rear surface of the radiator 15 d so that the air intake surface 21 a of the oil cooler 20 is perpendicular to the air intake surface 17 a of the radiator 15, the exhaust frame 23 attached to the oil cooler 20 can be attached to the radiator 15. It can be prevented that the radiator core 15a protrudes greatly, and the influence of the oil cooler 20 on the cooling efficiency due to the obstruction of the ventilation of the radiator 15 can be minimized.

  As shown in FIG. 7, when a water-cooled AT cooler 25 for cooling AT oil using cooling water in one side tank 15d of the radiator 15 is accommodated in the side tank 15d, The air-cooled oil cooler 20 fixed to the side tank 15d can be connected to the water-cooled AT cooler 25.

  The water-cooled AT cooler 25 is provided with a connection fitting 25a protruding from the side tank 15d. The water-cooled AT cooler 25 is provided with a connection fitting 25b protruding from the side tank 15d. The air-cooled oil cooler 20 has an upper tank 20a and a lower tank 20b, and the upper tank 20a is provided with a connection fitting 20c connected to the automatic transmission.

  The automatic transmission is configured such that one connection fitting 25a of the water-cooled AT cooler 25 and the connection fitting 20c of the air-cooled oil cooler 20 pass through a connection hose (not shown) so that the two oil coolers 20 and 25 are connected in series. The other connection fitting 25b of the water-cooled AT cooler 25 is connected to the lower tank 20b of the air-cooled oil cooler 20. For this connection, as shown in FIG. 8, a connection opening 20d is formed in the lower tank 20b of the water-cooled oil cooler 20, and a circular seal member 26 is attached to the connection opening. The other connection fitting 25 b of the water-cooled AT cooler 25 is inserted through the circular seal member 26, whereby the both coolers 20 and 25 are directly and airtightly connected via the circular seal member 26.

  The two oil coolers 20 and 25 can be connected in series with each other via a relay hose (not shown). As described above, the relay hose is eliminated by directly connecting the two oil coolers 20 and 25 with the connection fitting 25b. This can reduce costs and weight.

  Further, as shown in FIG. 9, an air-cooled oil cooler 20 provided with an air supply duct 22 and a support member 27 that holds the radiator 15, the radiator 15 and the oil cooler 20 are integrated in advance as a front end module 28. I can leave. Thus, it is not necessary to mount the oil cooler 20 having the air supply duct 22 alone on the vehicle 10, and after the front end module 28 is mounted on the vehicle 10, the radiator 15 and the oil are connected by completing connection work for necessary piping. Since the work of mounting the cooler 20 on the vehicle 10 is completed, the work time can be shortened and the work performance can be improved.

  As described above, the AT oil cooler 20 is shown as a heat exchanger in which the air intake surface 21a is arranged along the front-rear direction of the vehicle 10 at the rear side portion of the radiator 15, and along the example of the AT oil cooler 20. As described above, instead of the heat exchanger composed of the AT oil cooler, the cooling water supplied to the oil cooler or the radiator 15 that cools the PS oil that is the fluid to be cooled higher than the cooling water temperature supplied to the radiator 15. A heat exchanger such as an intercooler that cools the high-temperature supply air that is a fluid to be cooled that is higher in temperature than the temperature can be disposed on the rear side of the radiator with the air intake surfaces along the front-rear direction of the vehicle.
