Summary of Invention

Problems to be Solved by the Invention

[0004] However, the inventions described in each of the aforementioned patent documents have room for improvement from the perspective of improving aerodynamic performance in consideration of the performance of the radiator.

[0005] Specifically, the airflow that has undergone heat exchange by the radiator inside the engine compartment is released outside the vehicle through the engine compartment and wheel wells. On the other hand, it is known that when a crosswind acts on a moving vehicle, the vehicle is thrown in the yaw direction. Here, the yaw direction is the direction of rotation with the vertical direction as the axis of rotation. When this happens, a low-pressure region is generated on the side of the vehicle, air outflow from the wheel wells becomes significant, the convergence of the airflow near the sides and rear of the vehicle decreases, and the aerodynamic performance deteriorates.

[0006] This invention has been made in view of the above problems, and the object of this invention is to provide a vehicle heat exchange device that is installed in a vehicle having a heat exchanger such as a radiator and improves aerodynamic performance. [Means for solving the problem]

[Figure 3] This is a flowchart showing the operation of a vehicle heat exchanger according to an embodiment of the present invention. [Figure 4] This is a top view showing a first operating mode of a vehicle heat exchanger according to an embodiment of the present invention. [Figure 5] This is a top view showing a second operating mode of a vehicle heat exchanger according to an embodiment of the present invention. [Modes for carrying out the invention]

[0010] Hereinafter, a vehicle heat exchange device 20 and a vehicle 10 according to an embodiment of the present invention will be described in detail with reference to the drawings. In the following description, the directions of front, rear, up, down, left, and right will be used, but left and right will refer to the left and right when the vehicle 10 is viewed from the rear. Furthermore, in the following description, the same reference numerals will be used for the same components in principle, and repeated explanations will be omitted.

[0011] Figure 1 is a top view showing a vehicle 10 equipped with a vehicle heat exchanger 20.

[0012] Vehicle 10 can be, for example, a gasoline engine vehicle, a BEV (Battery Electric Vehicle), a HEV (Hybrid Electric Vehicle), or a PHEV (Plug-in Hybrid Electric Vehicle).

[0013] Vehicle 10 has a body 11. A tire hood 13 is formed on the body 11. The tire hood 13 has a left tire hood 131 and a right tire hood 132. Tires (not shown) are disposed on the left tire hood 131 and the right tire hood 132, respectively.

[0014] The vehicle heat exchanger 20 is a device mounted on a vehicle 10 and configured to cool in-vehicle equipment 12. The vehicle heat exchanger 20 mainly comprises a driving condition detection unit 28, a heat exchange unit 21, an angle changing unit 22, a temperature detection unit 23 (described later), and a calculation control unit 24 (described later). As described later, the in-vehicle equipment 12 cooled by the vehicle heat exchanger 20 is, for example, an engine or a battery. By using an engine as the in-vehicle equipment 12, the engine can be effectively cooled by the radiator 211 (described later). By using a large battery, such as those mounted in BEVs, HEVs, or PHEVs, as the in-vehicle equipment 12, the battery can be effectively cooled.

[0015] The heat exchange unit 21 is configured such that a medium circulating between it and the on-board equipment 12 exchanges heat. For example, a radiator 211 can be used as the heat exchange unit 21. The radiator 211 is connected to the aforementioned on-board equipment 12 via piping (not shown here). The radiator 211 is a fin-and-tube type, for example, comprising stacked heat dissipation fins and tubes that penetrate the heat dissipation fins. The heat dissipation fins are metal plates made of aluminum, copper, or the like. These heat dissipation fins have main surfaces that face either vertically or horizontally. Cooling water, which acts as a heat exchange medium, circulates between the radiator 211 and the on-board equipment 12, thereby effectively cooling the on-board equipment 12, such as the engine or a large battery.

[0016] The angle changing unit 22 is configured to change the angle of the heat exchange unit 21 with a vertical rotation shaft 30 extending along the vertical direction as the rotation center. Here, the vertical rotation shaft 30 is disposed at the intermediate portion of the heat exchange unit 21 in the vehicle width direction. Further, the angle changing unit 22 is installed at the central portion of the radiator 211 in the vehicle width direction. Specifically, the angle changing unit 22 supports the radiator 211 in a state rotatable relative to the vehicle body 11. The angle changing unit 22 includes an actuator such as a motor (not shown here). By the driving force of this actuator, the radiator 211 can be rotated about the vertical rotation shaft 30 as the rotation center. When viewed from above, the radiator 211 can rotate clockwise and can also rotate counterclockwise. Normally, the angle changing unit 22 brings the main surface of the radiator 211 into a state facing forward.

[0017] When the vehicle 10 is a BEV, since the engine and its peripheral devices are not disposed inside the engine room 17, there are few space constraints inside the engine room 17. Therefore, particularly when the vehicle 10 is a BEV, the space for arranging the vehicle heat exchange device 20 and the space for the radiator 211 to rotate can be easily secured inside the engine room 17.

[0018] The front grille 16 is formed on the front surface of the vehicle body 11. The front grille 16 is made of, for example, a synthetic resin member having a lattice shape. The engine room 17 communicates with the outside via the front grille 16. When the vehicle 10 travels, traveling wind is sent from the vehicle front side into the engine room 17 via the front grille 16.

[0019] The traveling condition detection unit 28 is a sensor that is disposed on the vehicle body 11 and measures the pressure acting along the vehicle body width direction. As the traveling condition detection unit 28, a sensor 281 disposed in a pressure hole can be adopted. The sensors 281 are disposed at a plurality of positions on the vehicle body 11. The sensors 281 are disposed at front bumper corners of the vehicle body 11. Here, the sensors 281 are disposed at the left end and the right end at the front end portion of the vehicle body 11. Further, a shark fin antenna 31 is disposed near the rear end of the upper surface of the vehicle body 11, and the sensor 281 is also disposed on the shark fin antenna 31. The sensor 281 detects the magnitude of the pressure acting along the vehicle width direction. Therefore, when the sensor 281 detects a pressure equal to or higher than a certain level, it is possible to detect that a strong crosswind is acting on the traveling vehicle 10.

[0020] Figure 2 is a block diagram showing a connection configuration of the vehicle heat exchange device 20.

[0021] The vehicle heat exchange device 20 mainly includes a temperature detection unit 23, a vehicle speed detection unit 27, a traveling condition detection unit 28, a calculation control unit 24, an angle changing unit 22, and an on-vehicle device 12.

[0022] The temperature detection unit 23 is configured to detect the temperature of a medium or a device 26 through which the medium flows. Here, the device 26 is, for example, a radiator 211, a pipe connecting the radiator 211 and an engine or a battery, or the like. Further, the medium is, for example, cooling water. Information indicating the temperature detected by the temperature detection unit 23 is transmitted to the calculation control unit 24.

[0023] The vehicle speed detection unit 27 detects the traveling speed of the vehicle 10 during traveling. Information indicating the traveling speed detected by the vehicle speed detection unit 27 is transmitted to the calculation control unit 24.

[0024] The traveling condition detection unit 28 is configured to detect a crosswind acting on the vehicle 10. The traveling condition detection unit 28 is, for example, the aforementioned sensor 281 that detects pressure. Information indicating the magnitude of the pressure detected by the sensor 281 is transmitted to the calculation control unit 24.

[0025] As described above, the angle changing unit 22 is an actuator that changes the angle of the radiator 211 based on instructions given by the calculation control unit 24.

[0026] The in-vehicle equipment 12 is equipment that is cooled by the radiator 211 mentioned above, and is, for example, an engine or battery that generates heat when in operation.

[0027] The arithmetic control unit 24 consists of semiconductor elements such as a CPU (Central Processing Unit). The arithmetic control unit 24 may also include semiconductor memory devices such as RAM (Random Access Memory) and ROM (Read Only Memory) as storage units. Such storage units store programs, parameters, etc. Based on the programs, parameters, etc. read from the storage units, the arithmetic control unit 24 executes the functions and methods described later.

[0028] In this embodiment, the calculation control unit 24 changes the angle of the heat exchange unit 21 using the angle change unit 22 based on the temperature detected by the temperature detection unit 23 and the driving conditions detected by the driving conditions detection unit 28. Furthermore, if the driving conditions detection unit 28 detects a crosswind, the calculation control unit 24 changes the angle of the heat exchange unit 21 using the angle change unit 22. Also, if the temperature detected by the temperature detection unit 23 does not exceed a preset threshold temperature, the calculation control unit 24 rotates the heat exchange unit 21 so that it tilts forward toward the windward side in the crosswind flow. Furthermore, if the temperature detected by the temperature detection unit 23 exceeds a preset threshold temperature, the calculation control unit 24 rotates the heat exchange unit 21 so that it tilts forward toward the leeward side in the crosswind flow. The functions of the calculation control unit 24 will be described later with reference to Figures 3 and later.

[0029] Figure 3 is a flowchart showing the operation of the vehicle heat exchanger 20.

[0030] In step S10, the calculation control unit 24 drives the vehicle 10. Specifically, referring to Figure 1, based on instructions from the occupants and the calculation control unit 24, the tires are rotated by the driving force of the engine or motor mounted on the vehicle body 11. This causes the vehicle 10 to move. As the vehicle 10 moves, airflow is generated. This airflow flows along the surface of the vehicle body 11 toward the rear.

[0031] In step S11, the calculation control unit 24 determines whether or not a crosswind of a certain magnitude or greater is acting on the vehicle 10. Specifically, as shown in Figure 1, sensors 281 are provided at multiple locations on the vehicle body 11. The sensors 281 detect the magnitude of the pressure acting along the width direction of the vehicle. Therefore, if the pressure acting on the sensors 281 is above a certain magnitude, the calculation control unit 24 determines that a crosswind with a flow velocity of a certain magnitude or greater is acting on the moving vehicle 10.

[0032] If the answer in step S11 is YES, that is, if a certain level of crosswind is acting on the vehicle 10, the calculation control unit 24 proceeds to step S12.

[0033] If the answer in step S11 is NO, that is, if the vehicle 10 is not subjected to a crosswind of a certain magnitude or greater, the calculation control unit 24 returns to step S10.

[0034] In step S12, the calculation control unit 24 measures the coolant temperature at the inlet of the radiator 211 using a temperature sensor. The calculation control unit 24 then determines whether or not the coolant temperature exceeds a predetermined threshold temperature.

[0035] If the answer in step S12 is YES, that is, if the water temperature does not exceed the threshold temperature, the calculation control unit 24 proceeds to step S13, which prioritizes the driving stability of the vehicle 10.

[0036] If the answer in step S12 is NO, that is, if the water temperature exceeds the threshold temperature, the calculation control unit 24 proceeds to step S16, which prioritizes heat exchange in the radiator 211.

[0037] In step S13, the calculation control unit 24 performs a first operation mode to improve driving stability.

[0038] The first operating mode will be explained with reference to Figure 4. In Figure 4, the airflow directed towards the rear is shown by a dashed line, and the crosswind is shown by a double dashed line. Furthermore, in Figure 4, the crosswind blowing to the left acts on the vehicle 10, causing the vehicle 10 to swing in the yaw direction. That is, the front of the vehicle 10 swings to the left.

[0039] When vehicle 10 is moving, airflow passes around it towards the rear. Depending on weather conditions, a crosswind may also blow towards the left of the moving vehicle 10. If the crosswind blowing towards the left acts strongly on vehicle 10, a first low-pressure region 32 is formed near the left side of the vehicle body 11. The first low-pressure region 32 is a region where the air pressure is locally lower than in other regions. In this case, if no countermeasures are taken, a force will be generated that pulls the front of the vehicle body 11 to the left, which may worsen the driving stability of vehicle 10.

[0040] In this embodiment, the calculation control unit 24 tilts the radiator 211 using the angle changing unit 22. Specifically, the calculation control unit 24 rotates the radiator 211 so that it tilts forward toward the windward side in the crosswind flow. That is, when the radiator 211 is viewed from above, the angle changing unit 22 rotates the radiator 211 counterclockwise.

[0041] In this configuration, the airflow introduced into the engine compartment 17 via the front grille 16 is guided by the radiator 211 and travels towards the rear right. Subsequently, the airflow is released outside the vehicle via the right tire hood 132. This creates a second low-pressure region 33 near the right tire hood 132. As a result, the vehicle 10 has a first low-pressure region 32 on the left side and a second low-pressure region 33 on the right side. Therefore, the leftward and rightward pressures are balanced at the front of the vehicle 10, preventing the front of the vehicle 10 from swaying strongly to the left, thus improving the driving stability of the vehicle 10. In addition, since the airflow flows smoothly along both sides of the vehicle body 11, the convergence of the airflow at the rear of the vehicle 10 is improved.

[0042] Furthermore, the amount of airflow released to the outside of the vehicle from the left tire hood 131, which is on the downwind side, can be reduced. As a result, the vehicle 10 will not swing significantly in the yaw direction, that is, the front of the vehicle 10 will not swing to the left. This suppresses the generation of negative pressure due to the formation of vortices on the rear side of the vehicle body 11, and the aerodynamic performance of the vehicle 10 is improved.

[0043] In step S14, the calculation control unit 24 determines, based on the output of the sensor 281, whether or not a certain level of crosswind is still acting on the vehicle 10.

[0044] If the answer in step S14 is YES, that is, if a certain level of crosswind is still acting on the vehicle 10, the calculation control unit 24 returns to step S13 and continues in the first operating mode.

[0045] If the answer in step S14 is NO, that is, if the vehicle 10 is not subjected to a crosswind of a certain magnitude or greater, the calculation control unit 24 proceeds to step S15.

[0046] In step S15, the calculation control unit 24 terminates the first operation mode. That is, as shown in Figure 1, the calculation control unit 24 rotates the radiator 211 using the angle changing unit 22. As a result, the main surface of the radiator 211 faces forward.

[0047] In step S16, the arithmetic control unit 24 executes a second operating mode that promotes heat exchange in the radiator 211.

[0048] The second operating mode will be explained with reference to Figure 5. In Figure 5, as in Figure 4, a crosswind blowing to the left acts on the vehicle 10, causing the vehicle 10 to swing in the yaw direction. That is, the front of the vehicle 10 swings to the left.

[0049] In the second operating mode, the calculation control unit 24 rotates the radiator 211 so that it tilts forward toward the leeward side in the crosswind flow. Specifically, based on the instructions of the calculation control unit 24, the angle change unit 22 rotates the radiator 211 clockwise around the vertical rotation axis 30 as the center of rotation. As a result, when the radiator 211 is viewed from above, it tilts forward toward the left.

[0050] As a result, when the vehicle 10 is in motion, the airflow introduced from the front grille 16 into the engine compartment 17 exchanges heat with the radiator 211 and is then guided by the radiator 211 to travel towards the rear left. Subsequently, the airflow passes through the left tire hood 131 and is discharged outside the vehicle from the left side of the vehicle body 11. At this time, the negative pressure in the first low-pressure region 32 draws the airflow outside the vehicle. Therefore, the airflow rate passing through the radiator 211 is increased, promoting heat exchange in the radiator 211 and effectively cooling onboard equipment 12, such as the engine. Furthermore, since step S16 is not a control that improves driving performance, it can be applied to low-speed driving situations such as when the vehicle speed of the vehicle 10 is below a threshold speed.

[0051] In step S17, the calculation control unit 24 determines, based on the output of the sensor 281, whether or not a certain level of crosswind is still acting on the vehicle 10.

[0052] If the answer in step S17 is YES, that is, if a certain level of crosswind is still acting on the vehicle 10, the calculation control unit 24 returns to step S16 and continues in the second operating mode.

[0053] If the answer in step S17 is NO, that is, if the vehicle 10 is not subjected to a crosswind of a certain magnitude or greater, the calculation control unit 24 proceeds to step S15.

[0054] In step S18, the calculation control unit 24 terminates the second operation mode. That is, as shown in Figure 1, the calculation control unit 24 rotates the radiator 211 using the angle changing unit 22. As a result, the main surface of the radiator 211 faces forward.

[0055] In step S19, the vehicle 10 stops based on the instructions of the arithmetic control unit 24.

[0056] The above is a description of the operation of the vehicle 10 and the vehicle heat exchanger 20 according to this embodiment.

[0057] The technical concepts that can be understood from the above-mentioned embodiment, along with their effects, are described below.

[0058] A vehicle heat exchanger according to an embodiment of the present invention is a vehicle heat exchanger configured to be mounted on a vehicle and to cool in-vehicle equipment, and comprises a driving condition detection unit, a heat exchange unit, an angle changing unit, a temperature detection unit, and a calculation control unit, wherein the driving condition detection unit is configured to detect the driving condition of the vehicle, the heat exchange unit is configured to exchange heat with a medium circulating between it and the in-vehicle equipment, the angle changing unit is configured to change the angle of the heat exchange unit with a vertical rotation axis extending in the vertical direction as the center of rotation, the temperature detection unit is configured to detect the temperature of the medium or the equipment through which the medium flows, and the calculation control unit changes the angle of the heat exchange unit by the angle changing unit based on the temperature detected by the temperature detection unit and the driving condition detected by the driving condition detection unit.According to the vehicle heat exchanger of the present invention, by changing the angle of the heat exchange unit with a vertical rotation axis extending in the vertical direction as the center of rotation based on the temperature of the heat exchange unit and the driving condition, heat exchange in the heat exchange unit can be actively performed and driving stability can be improved.

[0059] Furthermore, in the vehicle heat exchanger according to the embodiment of the present invention, the vertical rotation shaft is characterized in that it is located in the middle of the heat exchange section in the vehicle width direction. According to the vehicle heat exchanger of the present invention, by locating the vertical rotation shaft in the middle of the heat exchange section in the vehicle width direction, the heat exchange section can be tilted backward toward the left. Conversely, the heat exchange section can be tilted backward toward the right.

[0060] Furthermore, in the vehicle heat exchange device according to an embodiment of the present invention, the driving condition detection unit is configured to detect crosswinds acting on the vehicle, and the calculation control unit changes the angle of the heat exchange unit using the angle changing unit when the driving condition detection unit detects the crosswind. According to the vehicle heat exchange device of the present invention, when a crosswind is acting on the vehicle, the angle of the heat exchange unit can be changed to improve heat exchange in the heat exchange unit and driving stability.

[0061] Furthermore, in the vehicle heat exchange device according to an embodiment of the present invention, the calculation control unit rotates the heat exchange unit so that it tilts forward toward the windward side in the crosswind flow, provided that the temperature detected by the temperature detection unit does not exceed a preset threshold temperature. According to the vehicle heat exchange device of the present invention, when a crosswind occurs on a vehicle, a low-pressure region is formed near the side of the vehicle corresponding to the leeward side in the crosswind flow. By rotating the heat exchange unit so that it tilts forward toward the windward side in the crosswind flow, the airflow is blown out of the vehicle from the side of the vehicle corresponding to the windward side in the crosswind flow. This allows another low-pressure region to be formed on the side of the vehicle corresponding to the windward side. Therefore, since low-pressure regions can be formed near both sides of the vehicle, the stability of the vehicle while it is traveling can be improved.

[0062] Furthermore, in the vehicle heat exchange device according to an embodiment of the present invention, the calculation control unit rotates the heat exchange unit so that it tilts forward toward the leeward side in the crosswind flow when the temperature detected by the temperature detection unit exceeds a preset threshold temperature. According to the vehicle heat exchange device of the present invention, when a crosswind is generated on the vehicle, a low-pressure region is formed near the side of the vehicle corresponding to the leeward side in the crosswind flow. By rotating the heat exchange unit so that it tilts forward toward the leeward side in the crosswind flow, the airflow that has passed through the heat exchange unit can be blown out near the low-pressure region. Therefore, this blowing out can be promoted by the low-pressure region, promoting heat exchange in the heat exchange unit and effectively cooling the engine and the like.

[0063] Furthermore, in the vehicle heat exchange device according to the embodiment of the present invention, the heat exchange section is characterized by being a radiator. According to the vehicle heat exchange device of the present invention, by changing the direction in which the airflow is blown out after heat exchange by the radiator, the efficiency of heat exchange can be improved and driving stability can be improved.

[0064] Furthermore, in the vehicle heat exchange device according to the embodiment of the present invention, the driving condition detection unit is a sensor that is installed on the vehicle body and measures the pressure acting along the width direction of the vehicle body. According to the vehicle heat exchange device of the present invention, it is possible to accurately detect the crosswind acting on the vehicle when it is moving.

[0065] Although embodiments of the present invention have been described above, the present invention is not limited thereto, and modifications are possible without departing from the spirit of the invention. Furthermore, the above-described embodiments can be combined with each other.

[0066] For example, referring to Figures 3 to 5, in step S13, the angle at which the angle changing unit 22 tilts can also be adjusted. Specifically, the calculation control unit 24 can adjust the tilt angle of the radiator 211 to improve aerodynamic performance based on the magnitude and angle of the crosswind detected by the sensor 281. For example, referring to Figure 4, if the flow velocity of the crosswind detected by the sensor 281 is high, the calculation control unit 24 increases the tilt angle of the radiator 211. By doing so, the flow rate of the airflow released to the outside of the vehicle from the vicinity of the right tire hood 132 is increased, and the effect of forming the second low-pressure region 33 can be greatly enhanced.
