Summary of the Invention

Problems to be Solved by the Invention

[0004] When multiple cooling devices are arranged in parallel in front of a fan, gaps are formed between the cooling devices. When the fan is driven and creates airflow, the air passes through the cooling devices in order from the frontmost one. In parallel-arranged cooling devices, there is a gap between the front cooling device and the rear cooling device. As a result, the air that has been heated through heat exchange with the front cooling device wraps around to the rear cooling device and stagnates in the gap. This stagnation of air in the gap reduces the airflow that cools the cooling devices, and also increases the temperature of the air passing through the cooling devices. Therefore, conventional carriers had poor cooling efficiency for cooling devices.

[0005] The present invention was made to solve the above-mentioned problems, and aims to provide a technology that can efficiently cool each cooling device in a carrier that cools multiple cooling devices by passing air through them. [Means for solving the problem]

[0006] One aspect of the present invention is a carrier comprising (1) a fan that generates an airflow for taking in outside air, and a plurality of cooling devices that are cooled by heat exchange with the air taken in by the fan, wherein the plurality of cooling devices are arranged in parallel in front of the fan, with gaps between adjacent cooling devices, and each has a rectifier member that guides the outside air into the gaps, and a suppression part that prevents air from flowing into the gaps from outside the rectifier member.

[0007] In the carrier configuration described above, when the fan generates an airflow drawing in outside air, this air passes through a plurality of cooling devices arranged in parallel in front of the fan, cooling them. At this time, the airflow straightening member guides a portion of the air drawn in from the fan into a gap provided between the plurality of cooling devices, preventing it from passing through the cooling devices in front. The gap is prevented from receiving air from outside the airflow straightening member by a suppression part. Therefore, the air drawn in from the fan is able to pass through the cooling devices more easily without stagnating in the gap. Also, the air guided into the gap by the airflow straightening member is at a lower temperature than the air that has passed through the cooling devices in front, as it has not passed through the cooling devices in front as described above. In other words, the air that has passed through a cooling device is cooled in the gap before passing through the next cooling device. Therefore, the carrier configuration described above promotes the passage of air through each cooling device and suppresses the rise in ambient temperature around the cooling devices, thus enabling efficient cooling of each cooling device.

[0008] (2) In the carrier described in (1), the adjacent cooling devices preferably have an upper end of the cooling device located on the fan side that protrudes above the upper end of the cooling device located on the opposite side of the fan, and the air straightening member preferably has an opening that opens toward the upstream side of the airflow, and an inclined portion that is inclined in accordance with the upper end positions of the plurality of cooling devices and forms a guide path between itself and the plurality of cooling devices that guides the air flowing into the opening into the gap.

[0009] In the carrier configuration described above, the inclined section is tilted to correspond to the upper end positions of multiple cooling devices, which narrows the cross-sectional area of ​​the guide path between the cooling devices and the inclined section. This suppresses a decrease in the flow velocity of the air flowing through the guide path and allows outside air entering the opening to be guided to the cooling device adjacent to the fan.

[0010] (3) In the carrier described in (2), the gap has a first gap provided between the first cooling device and the second cooling device, and a second gap provided between the second cooling device and the third cooling device, and the suppression portion preferably has the upper edge portion of the peripheral edges of the first gap and the second gap open to communicate with the guide path, and the remaining portion closed by an air straightening member or a sealing member.

[0011] In the carrier configuration described above, the upper edges of both the first and second gaps are connected to guideways provided above them, and the remaining parts of the peripheral edges are sealed by airflow rectifiers or sealing members, thus allowing for a simple and compact configuration of the restraining section.

[0012] Another aspect of the present invention is (4) a carrier cooling module mounted on a carrier, wherein cooling devices that are cooled by heat exchange with air are arranged in parallel with a gap between them, and the module includes an airflow guider that guides air taken in from outside the carrier into the gap, and a suppression part that suppresses air from flowing into the gap from outside the airflow guider. [Effects of the Invention]

[0013] Therefore, according to the present invention, it is possible to provide a technology that can efficiently cool each cooling device in a carrier that cools multiple cooling devices by passing air through them. [Brief explanation of the drawing]

Embodiments for Carrying out the Invention

[0015] Hereinafter, a carrier and a cooling module for the carrier according to an embodiment of the present invention will be described with reference to the drawings. In this embodiment, for example, a carrier for transporting heavy objects at a steel mill, a shipyard, a shipping yard, etc., and a carrier in which air-cooled cooling devices are arranged in parallel in front of a fan will be disclosed.

[0016] <Schematic Configuration of Carrier 1> FIG. 1 is a side view of the carrier 1. In the carrier 1, a driver's seat 3 is provided at the longitudinal front end of the loading platform 2. Below the loading platform 2, a plurality of traveling devices 6 having a plurality of wheels are provided. The traveling device 6 is provided with a hydraulic motor 7 for applying a rotational driving force to the wheels, or a pneumatic brake 8 for braking the wheels. Each traveling device 6 is provided with a steering cylinder (not shown). The carrier 1 can perform diagonal travel, lateral travel, etc. as the traveling device 6 is independently steered and driven. The hydraulic motor 7 and the steering cylinder (not shown) are operated by hydraulic oil whose hydraulic pressure is adjusted by a hydraulic device (not shown). An engine room 5 for housing the engine 4 is provided at the longitudinal rear end of the loading platform 2.

[0017] FIG. 2 is an enlarged view (front view) of the engine room 5. FIG. 3 is a left side view of FIG. 2. FIG. 4 is a top view of FIG. 2. FIG. 5 is a cross-sectional view taken along the line A-A of FIG. 2. In FIGS. 1 to 5, for the sake of easy viewing of the drawings, the fan 11, the module 20, and the wind rectifying member 41 are shown by solid lines, and the other loading platform 2 and engine room 5 are appropriately simplified and shown by a two-dot chain line. Also, in FIG. 5, for the sake of easy viewing of the drawings, each cooling device is simplified, and further, the hatching of the members is omitted.

[0018] The engine room 5 has a ventilation opening 5a that opens to the side of the vehicle. Between the engine 4 and the ventilation opening 5a in the engine room 5, a fan 11, a carrier cooling module 20 (hereinafter referred to as "module 20"), and a wind rectifying member 41 are arranged.

[0019] As shown in FIGS. 3 and 4, the fan 11 is arranged to face the ventilation opening 5a and is connected to the engine 4. The fan 11 is rotationally driven by the engine 4 and generates an air flow that takes in outside air through the ventilation opening 5a.

[0020] As shown in FIGS. 2, 3, and 4, the module 20 is formed by arranging an intercooler 21, an oil cooler 22, and a radiator 23 in parallel and integrally connecting them. The module 20 is attached to the bottom 5b of the engine room 5 via a pair of legs 30, 30 in a state where the fan 11 faces the radiator 23 (a state where the air flowing in from the ventilation opening 5a passes through the intercooler 21, the oil cooler 22, and the radiator 23 in that order). As shown in FIGS. 3 and 4, the fan 11 is rotatably accommodated in a fan accommodation portion 29 provided in the radiator 23 of the module 20.

[0021] The intercooler 21 is an air-cooled cooling device that exchanges heat with air to cool the intake air of the engine 生4. The oil cooler 22 is an air-cooled cooling device that exchanges heat with air to cool the hydraulic oil. The radiator 23 is an air-cooled cooling device that exchanges heat with air to cool the cooling water of the engine.

[0022] As shown in FIG. 5, the module 20 has a first gap S1 between the intercooler 21 and the oil cooler 22, and a second gap S2 between the oil cooler 22 and the radiator 23. Details of the module 20 will be described later.

[0023] The intercooler 21, oil cooler 22, and radiator 23 are examples of "multiple cooling devices." Furthermore, the intercooler 21 is an example of a "first cooling device," the oil cooler 22 is an example of a "second cooling device," and the radiator 23 is an example of a "third cooling device." Additionally, the intercooler 21, oil cooler 22, and radiator 23 are examples of "adjacent cooling devices."

[0024] As shown in Figures 3 to 5, the airflow rectifier 41 is attached to the module 20 so as to guide the air taken in from outside the vehicle by the fan 11 into the first gap S1 and the second gap S2. Details of the airflow rectifier 41 will be described later.

[0025] Furthermore, as shown in Figures 3 to 5, the peripheral edge of the first gap S1 is sealed at the left and right edges and the lower edge by a pair of mounting brackets 28, 28 and an air rectifier 41, which will be described later, thereby suppressing the inflow of air from outside the air rectifier 41. Also, as shown in Figures 3 and 5, the peripheral edge of the second gap S2 is sealed at the left and right edges and the lower edge by a sealing member 26, which will be described later, thereby suppressing the inflow of air from outside the air rectifier 41. Note that the pair of mounting brackets 28, 28, the air rectifier 41 and the sealing member 26 are examples of "suppression parts".

[0026] <Configuration of Module 20> Figure 6 is an external perspective view of module 20. Figure 7 is a cross-sectional perspective view of Figure 6. Note that in Figures 6 and 7, some components have been omitted or their shapes simplified for clarity.

[0027] As shown in Figure 6, the intercooler 21, oil cooler 22, and radiator 23 each have a thin rectangular parallelepiped shape. The intercooler 21, oil cooler 22, and radiator 23 each have a flow path (not shown) through which the object to be cooled (intake air, hydraulic oil, coolant) flows, and heat dissipation fins (not shown) that exchange heat with air. The object to be cooled is cooled by the intercooler 21, oil cooler 22, and radiator 23 exchanging heat with air that passes from the front 21a, 22a, 23a to the back 21b, 22b, 23b along the heat dissipation fins (not shown).

[0028] The oil cooler 22 and the radiator 23 are set to have approximately the same width (length in the left-right direction). The intercooler 21 is set to be narrower in width than the oil cooler 22. The intercooler 21, oil cooler 22, and radiator 23 are set to increase in overall height in that order.

[0029] As shown in Figures 6 and 7, the oil cooler 22 is positioned with its rear surface 22b facing the front surface 23a of the radiator 23, and its lower end is roughly aligned with the lower end of the radiator 23. The upper end of the oil cooler 22 is fixed to the front surface 23a of the radiator 23 using a fitting 24. Similarly, the lower end of the oil cooler 22 is fixed to the front surface 23a of the radiator 23 using a fitting (not shown). Therefore, the upper end of the radiator 23 protrudes above the upper end of the oil cooler 22.

[0030] A second gap S2 is provided between the oil cooler 22 and the radiator 23 in a substantially rectangular shape. The left and right edges and the lower edge of the peripheral portion of the second gap S2 are sealed by sealing members 26a, 26b, and 26c, respectively. On the other hand, the upper edge portion of the second gap S2 is not sealed.

[0031] A guide plate 27 is fixed to the front surface 23a of the radiator 23. The guide plate 27 has a length approximately the same as the width of the radiator 23, and the cross-sectional shape when cut in a direction perpendicular to the length direction is arc-shaped. The guide plate 27 is positioned along the upper edge of the second gap S2 to guide air into the second gap S2.

[0032] The intercooler 21 is positioned with its rear surface (the side facing the fan 11) 21b facing the front surface (the side facing the fan 11) 22a of the oil cooler 22, and its lower end is roughly aligned with the lower end of the oil cooler 22. The left and right ends of the intercooler 21 are fixed to the oil cooler 22 and the radiator 23 using a pair of mounting brackets 28, 28. As a result, the upper end of the oil cooler 22 protrudes above the upper end of the intercooler 21. A first gap S1 is provided between the intercooler 21 and the oil cooler 22 in a roughly rectangular shape.

[0033] <Configuration of the airflow rectifier 41> Figure 8 is an external perspective view of the airflow rectifier 41. The airflow rectifier 41 comprises a first cover portion 42 and a second cover portion 43.

[0034] The first cover section 42 is assembled in a box shape from an upper plate member 423, a lower member 424, upper side plates 425, 426, intermediate side plates 427, 428, and lower side plates 429, 430, with a rectangular opening 42a provided in the portion facing the intercooler 21. The lower member 424 is formed in a U-shape in cross-section, and the lower end of the intercooler 21 is positioned so as not to contact it. The upper plate member 423 and the lower member 424 are bolted to the frame side forming the engine room 5. The upper end of the intermediate side plate 427 and the upper side plate 425 are overlapped and fixed with bolts V. The lower end of the intermediate side plate 427 and the lower side plate 429 are overlapped and fixed to the lower member 424 with bolts V. The upper side plate 426, intermediate side plate 428, and lower side plate 430 are fixed in the same manner.

[0035] The second cover section 43 has a front plate 431 joined to the front edge of the upper cover plate 432, and side cover plates 433 and 434 joined to the left and right side edges of the upper cover plate 432. The front plate 431 is inclined to correspond to the upper end positions of the intercooler 21, oil cooler 22, and radiator 23. The front plate 431 is an example of an "inclined section". The side cover plates 433 and 434 are formed in a trapezoidal shape so as to cover the upper sides of the radiator 23, oil cooler 22, and intercooler 21. Dustproof rubber 45 is bonded to the second cover section 43 along the rear edge of the upper cover plate 432 and the rear edges of the side cover plates 433 and 434.

[0036] Figure 9 is a conceptual diagram showing the airflow. The airflow straightening member 41 is positioned so that the lower end of the intercooler 21 is not in contact with the lower member 424, and the air flowing into the opening 42a hits the entire front surface 21a of the intercooler 21. Since the intercooler 21 is positioned behind the opening 42a, a clearance 54 is provided between the opening 42a and the front surface 21a of the intercooler 21.

[0037] The upper plate member 423 is fixed to the upper side plates 425 and 426 so as to be positioned above the intercooler 21 with a clearance 52. The opening 42a (see Figure 8) extends above the upper end of the front surface 21a of the intercooler 21.

[0038] The first gap S1 has its left and right edges blocked by the upper side plates 425, 426, intermediate side plates 427, 428, and lower side plates 429, 430 of the air rectifier 41, and its lower edge blocked by the lower member 424 of the air rectifier 41, thereby preventing air from flowing into the first gap S1 from outside the air rectifier 41. On the other hand, the upper edge of the first gap S1 is open to the clearance 54, and air flows in from the opening 42a.

[0039] As shown in Figures 3 and 4, the second cover portion 43 is fixed to the radiator 23 with bolts V using a pair of mounting plates 44, 44, with the dustproof rubber 45 (45a, 45b, 45c) in contact with the front surface 23a of the radiator 23.

[0040] As shown in Figure 9, the lower edge of the front plate 431 of the second cover portion 43 is close to the upper plate member 423 of the first cover portion 42. The front plate 431 has a clearance 51 between the oil cooler 22 and the radiator 23, and guides the air guided from the opening 42a into the clearance 52 to the upper part of the radiator 23.

[0041] The clearances 51 and 52 constitute a guide path 50 that directs a portion of the air flowing into the opening 42a to the first gap S1 and the second gap S2. Because the front plate 431 is inclined, the cross-sectional area of ​​the guide path 50 is narrowed between the front plate 431 and the oil cooler 22, which allows the flow velocity to be accelerated.

[0042] (Explanation of cooling operation) Next, the cooling operation of carrier 1 will be explained. When carrier 1 is driven by engine 4, fan 11 is rotated by engine 4, generating an airflow that draws in air from outside the vehicle through vent 5a. Carrier 1 travels slowly, for example, at a speed of about 10 km / h. Therefore, even though vent 5a opens to the side of carrier 1, the rotational drive of fan 11 alone is sufficient to generate an airflow that draws in air from outside the vehicle.

[0043] As shown in Figure 9, when the fan 11 is driven to rotate, outside air flows into the opening 42a of the air rectifier 41, as indicated by arrow X1 in the figure. The air that flows into the opening 42a passes from the intercooler 21 to the oil cooler 22 and then to the radiator 23, as indicated by arrows X2, X3, and X4 in the figure. The intercooler 21, oil cooler 22 and radiator 23 exchange heat with the air that flows in from the opening 42a and are cooled.

[0044] Furthermore, as shown by X11 in the figure, the air flowing into the opening 42a is also supplied to the clearance 52. This air then strikes the front surface 22a of the oil cooler 22, as shown by arrows X12 and X13 in the figure, and is divided into the first gap S1 and the clearance 51.

[0045] The first gap S1 is sealed at its side and lower edges by a pair of mounting brackets 28, 28 and an airflow straightening member 41, except for the upper edge which communicates with the guideway 50. This prevents the air heated by passing through the intercooler 21 from leaking to the outside. At the same time, the structure also makes it difficult for outside air to flow in from the side and lower edges of the first gap S1. Therefore, the air that has passed through the intercooler 21 does not remain in the first gap S1, but flows smoothly through the oil cooler 22 to the second gap S2, as shown by arrow X3 in the figure.

[0046] Furthermore, as shown by arrow X2 in the figure, the warm air supplied to the first gap S1 after passing through the intercooler 21 merges with the air flowing into the first gap from the clearance 52, as shown by arrow X12 in the figure, and is cooled. This suppresses the temperature rise within the first gap S1.

[0047] Therefore, the oil cooler 22 is cooled more efficiently than when the airflow rectifier 41 is not present, as the airflow rate to cool the oil cooler 22 is increased and the temperature of the air cooling the oil cooler 22 is suppressed.

[0048] As shown by arrow X13 in the figure, air is supplied to clearance 51 from clearance 52. As shown by arrow X14 in the figure, a portion of this air is guided by guide plate 27 and directed to the second gap S2. Then, as shown by X15 in the figure, the remainder is guided to the top of radiator 23 by front plate 431 of second cover portion 43 and passes through radiator 23 as shown by arrow X16 in the figure.

[0049] Furthermore, since a portion of the air flowing into the opening 42a is guided to the first gap S1 and the second gap S2, the amount of air supplied to the clearance 51 is reduced accordingly. However, because the front plate 431 is inclined, the cross-sectional area of ​​the guide path 50 narrows between the oil cooler 22 and the front plate 431. As a result, the air supplied to the clearance 51 has its flow velocity accelerated in the narrowed portion of the guide path 50 and is guided to the top of the radiator 23, thereby cooling the top of the radiator 23.

[0050] The second gap S2 is sealed at its left and right edges and bottom edge by the sealing member 26, preventing air from flowing in from outside the air rectifier 41. At the same time, the structure also prevents outside air from flowing in from the left and right edges and bottom edge of the second gap S2. Therefore, the air supplied from the oil cooler 22 to the second gap S2 does not remain in the second gap S2, but passes through the radiator 23 and is discharged outside the module 20, as shown by arrow X4 in the figure.

[0051] Furthermore, as shown by arrow X3 in the figure, the warm air supplied to the second gap S2 after passing through the oil cooler 22 merges with the air flowing into the second gap S2 from the clearance 51, as shown by arrow X14 in the figure, and is cooled. This suppresses the rise in temperature within the second gap S2 (i.e., the temperature of the air cooling the radiator 23).

[0052] Therefore, the radiator 23 is cooled more efficiently because it receives a larger volume of air to cool it and the temperature of the air cooling it is suppressed compared to when the air straightening member 41 and the sealing member 26 are not present.

[0053] (summary) As described above, in this embodiment of the carrier 1, when the fan 11 generates an airflow that takes in outside air, that air passes through the intercooler 21, oil cooler 22, and radiator 23, which are arranged in parallel in front of the fan 11, and cools them. At this time, the air straightening member 41 guides a portion of the air taken in from the fan 11 into the first gap S1 and the second gap S2 provided between the intercooler 21, oil cooler 22, and radiator 23, without passing through the intercooler 21 or oil cooler 22. The first gap S1 and the second gap S2 are protected from air inflow from outside the air straightening member 41 by a pair of mounting brackets 28, the upper side plates 425, 426, intermediate side plates 427, 428, lower side plates 429, 430, lower member 424, and sealing member 26 of the air straightening member 41. Therefore, the air taken in from the fan 11 does not stagnate in the first gap S1 and the second gap S2, but instead easily passes through the intercooler 21, oil cooler 22, and radiator 23. Also, the air guided into the first gap S1 and the second gap S2 by the air straightening member 41 does not pass through the intercooler 21 and oil cooler 22 as described above, and is therefore at a lower temperature than the air that has passed through the intercooler 21 and oil cooler 22. In other words, the air that has passed through the intercooler 21 and oil cooler 22 is cooled in the first gap S1 and the second gap S2 before passing through the oil cooler 22 and radiator 23. Thus, the carrier 1 of this embodiment promotes the passage of air through the intercooler 21, oil cooler 22, and radiator 23, and suppresses the rise in ambient temperature around the intercooler 21, oil cooler 22, and radiator 23, so that the intercooler 21, oil cooler 22, and radiator 23 can be cooled efficiently.

[0054] Furthermore, in this configuration, the carrier 1 has a front plate 431 that is inclined to correspond to the upper end positions of the intercooler 21, oil cooler 22, and radiator 23. As a result, the cross-sectional area of ​​the flow path 50 narrows between the oil cooler 22 and the front plate 431, which suppresses a decrease in the flow velocity of the air flowing through the guide path 50 and allows the outside air that flows into the opening 42a to be guided to the radiator 23 adjacent to the fan 11.

[0055] Furthermore, in this embodiment of the carrier 1, the upper edges of both the first gap S1 and the second gap S2 are connected to the guideway 50 provided above them, and the left and right edges and lower edges of the peripheral portion are closed by a pair of mounting brackets 28, the upper side plates 425, 426, intermediate side plates 427, 428, lower member 424, and sealing member 26 of the air rectifier member 41, thus making the configuration of the restraining part simple and compact.

[0056] Furthermore, the present invention is not limited to the above embodiments and can be applied in various ways. For example, the carrier 1 may have driver's seats at the front and rear of the cargo bed 2. Also, the use of the carrier 1 may differ from that of the above embodiments. The airflow rectifier 41 may not be attached to the module 20, but rather to the bottom 5b of the engine room 5.

[0057] The number and types of cooling devices constituting module 20 are not limited to the above embodiment. For example, if a hydraulic circuit is not provided, the oil cooler 22 may not be necessary. Also, for example, if a storage battery is provided, the capacitor of the storage battery may be further incorporated into module 20 as a cooling device. Furthermore, for example, the multiple cooling devices constituting module 20 may be of the same type.

[0058] The shape of the cooling devices and the shape of the gaps between multiple cooling devices may differ from those in the above embodiment. If the cooling devices are arranged in parallel, the upper end of the rear cooling device does not need to protrude above the upper end of the front cooling device.

[0059] The airflow rectifier 41 may be made up of a single component instead of multiple components. The opening 42a may differ from the above configuration. However, by making the opening 42a the same shape as the front surface 21a of the intercooler 21, outside air can be supplied to the entire front surface 21a, thereby increasing the cooling efficiency. The guide path 50 may be provided in a different location, such as to the side, rather than above the cooling device.

[0060] The front plate 431 does not need to be inclined according to the upper end positions of the intercooler 21, oil cooler 22, and radiator 23. [Explanation of Symbols]
