[0001] The invention relates to a heat exchange control device, and in particular to a heat exchange control device for an electric vehicle and a control method thereof. Background Art

[0002] In response to the increasing global emphasis on energy conservation, carbon reduction and environmental protection, countries around the world encourage electric vehicles to replace fuel vehicles. Therefore, electric vehicle technology has developed rapidly in recent years and has become the mainstream in the world. Compared with traditional fuel vehicles that use engines, gearboxes, etc. as power systems, electric vehicles mainly have three electric systems, which generally include motor systems (or electric drive systems), electronic control systems, and battery systems. In addition, electric vehicles usually have heat pump systems to adjust the temperature of the passenger cabin.

[0003] Since temperature changes will significantly affect the operation of the three-electric system, the cooling and heating mechanism is particularly important for electric vehicles. In order to regulate the operating temperature of the three-electric system, it is easy to cause extra energy consumption of the electric vehicle, resulting in a reduction in the mileage of the electric vehicle. Therefore, how to effectively improve the heat exchange regulation effect of electric vehicles through structural design improvements to overcome the above-mentioned defects has become one of the important issues that this business wants to solve. Summary of the invention

[0005] In order to solve the above-mentioned technical problems, one of the technical solutions adopted by the present invention is to provide a heat exchange control device for an electric vehicle. The heat exchange control device for an electric vehicle includes an airflow guide cover and an airflow adjustment member. The airflow guide cover includes an air inlet, an air outlet and an airflow channel between the air inlet and the air outlet. The air inlet is connected to the air inlet at the front end of the vehicle body. A water tank and a condenser are provided in the air flow channel and near the air outlet. The airflow adjustment member is provided on the inner side of the air inlet of the airflow guide cover. The airflow adjustment member is configured to adjust the air flow rate and airflow direction through the air inlet.

[0006] Furthermore, the airflow adjustment member includes a plurality of guide blades arranged at intervals, and the plurality of guide blades are arranged to perform a rotational swing operation relative to the air inlet to control the opening of the air inlet.

[0007] Furthermore, the heat exchange control device for an electric vehicle further includes a driver, the plurality of guide blades are actuated and linked to the driver, and the driver is configured to drive the plurality of guide blades to perform the rotation and swing operations according to control instructions.

[0008] Furthermore, the cross-sectional area of ​​the air flow channel gradually widens from the air inlet toward the air outlet, and the air outlet and the air inlet are arranged at an inclination.

[0009] Furthermore, the ratio of the cross-sectional area of ​​the air inlet to the cross-sectional area of ​​the air outlet is between 1:2 and 1:3.5.

[0010] Furthermore, the airflow guide cover includes an upper guide plate and a lower guide plate, and the upper guide plate and the lower guide plate are combined to form the air inlet, the airflow channel and the air outlet; wherein the upper guide plate has an airflow guide surface, the lower guide plate has an inner surface relative to the airflow guide surface, and the airflow guide surface and the inner surface extend from the air inlet to the air outlet in directions away from each other; wherein the extension distance of the airflow guide surface is greater than the extension distance of the inner surface.

[0011] Furthermore, the condenser is arranged at and occupies the air outlet; wherein the water tank is located between the condenser and the air inlet and close to the lower guide plate, and the water tank occupies 1 / 3 to 1 / 2 of the air outlet.

[0012] Furthermore, there is an inclination angle between the extension direction of the air inlet and the extension direction of the air outlet, and the inclination angle is between 45 degrees and 60 degrees; wherein the water tank and the condenser are inclined relative to the air inlet at a position close to the air outlet according to the inclination angle.

[0013] Furthermore, there is a guide angle between the extension direction of the air inlet and the extension direction of the airflow guide surface, and the guide angle is between 60 degrees and 90 degrees; wherein the guide angle is greater than the inclination angle.

[0014] Furthermore, the heat exchange control device for an electric vehicle further includes: at least one exhaust portion, at least one exhaust portion is arranged on a lower guard plate, and the lower guard plate is located below the front end of the vehicle body; wherein each exhaust portion includes an exhaust port facing the airflow guide cover and a rectification channel, the rectification channel is formed by the lower guard plate being recessed in the direction toward the inside of the electric vehicle, and the rectification channel gradually widens toward one end of the airflow guide cover and surrounds the exhaust port to form.

[0015] In order to solve the above technical problems, another technical solution adopted by the present invention is to provide a control method for a heat exchange control device of an electric vehicle, which includes the following steps. First, at least one detector senses at least one environmental parameter of the electric vehicle, and transmits at least one of the environmental parameters to the main controller of the electric vehicle. Then, the main controller determines a default heat exchange mode according to at least one of the environmental parameters, which is consistent with the current state of the electric vehicle. Finally, the main controller adjusts the airflow adjustment member in the heat exchange control device of the electric vehicle according to the default heat exchange mode to assist in regulating the cooling of the water tank and condenser of the electric vehicle. Wherein, the heat exchange control device includes an airflow guide cover and an airflow adjustment member.

When the default heat exchange mode is the fifth operation mode and the plurality of guide blades are in the fifth operation position of the rotation and swing operation, the opening of the air inlet is between 60% and 90%.

[0018] One of the beneficial effects of the present invention is that the heat exchange control device and control method for an electric vehicle provided by the present invention can effectively adjust the heat dissipation ratio of the water tank and the condenser through the technical scheme of "a water tank and a condenser are provided in the air flow channel and close to the air outlet" and "an air flow adjustment component is provided on the inner side of the air inlet of the air flow guide cover, and the air flow adjustment component is configured to adjust the air intake flow and airflow direction through the air inlet" so as to meet the cooling and heating requirements of the heat pump system for the three-electric system and the cabin air conditioning under different temperature environments according to the driving conditions of the electric vehicle.

[0030] First embodiment

[0031] See also Figure 1 and Figure 2 As shown, the first embodiment of the present invention provides a heat exchange control device for an electric vehicle, which mainly includes an airflow guide cover 10 and an airflow adjustment member 20 .

[0032] The airflow guide cover 10 includes an air inlet 11, an air outlet 12, and an airflow channel 13 between the air inlet 11 and the air outlet 12. In detail, the heat exchange control device for an electric vehicle of the present invention is mainly arranged at the front end of the vehicle body, and the air inlet 11 of the airflow guide cover 10 is connected to an air inlet at the front end of the vehicle body. Generally speaking, the air inlet at the front end of the vehicle body can be located at the position of the vehicle's air intake grille or front bumper, but is not limited thereto.

[0033] A water tank W and a condenser H are provided in the air flow channel 13 and near the air outlet 12. When the electric vehicle is in driving state, the external air flow will enter the air inlet at the front end of the vehicle, and then pass through the air inlet 11, the air flow channel 13 and the air outlet 12 of the air flow guide cover 10 in sequence, and perform heat exchange with the water tank W and the condenser H. Further, the water tank W and the condenser H are components of the three-electric system of the electric vehicle. Specifically, the water tank W can be a water tank W for motor cooling, and the condenser H can be a condenser H for battery air conditioning heat dissipation. Through the structural design of the air flow guide cover 10 and the configuration of the air flow adjustment part 20 of the present invention, the heat dissipation ratio of the water tank W and the condenser H can be effectively adjusted. The structure and configuration of the air flow guide cover 10 and the air flow adjustment part 20 will be described in detail below.

[0034] See also Figure 1 as well as Figure 2 As shown, the airflow guide cover 10 may further include an upper guide plate 14 and a lower guide plate 15, and the upper guide plate 14 and the lower guide plate 15 are combined to form the air inlet 11, the airflow channel 13 and the air outlet 12. In detail, the upper guide plate 14 has an airflow guide surface 141, and the lower guide plate 15 has an inner surface 151 relative to the airflow guide surface 141, and the airflow guide surface 141 and the inner surface 151 extend from the air inlet 11 to the air outlet 12 in a direction away from each other. It is worth noting that the extension distance of the airflow guide surface 141 of the upper guide plate 14 is greater than the extension distance of the inner surface 151 of the lower guide plate 15. In other words, the cross-sectional area of ​​the airflow channel 13 of the airflow guide cover 10 gradually widens from the air inlet 11 to the air outlet 12, and the air inlet 11 is inclined relative to the air outlet 12.

[0035] In the present embodiment, based on the ground plane where the electric vehicle is located, the air inlet 11 of the airflow guide cover 10 is arranged at a position at the front end of the vehicle perpendicular to the ground plane. Therefore, the air outlet 12 of the airflow guide cover 10 is arranged at an angle in the vehicle body, so that the air outlet 12 has a relatively large heat dissipation area. For example, the ratio of the cross-sectional area of ​​the air inlet 11 to the cross-sectional area of ​​the air outlet 12 can be between 1:2 and 1:3.5, preferably 1:2.5. The structural design of the airflow guide cover 10 of the present invention can make the airflow produce a Venturi effect to enhance the effect of heat exchange. However, the present invention is not limited to the above examples.

[0036] See also Figure 3 As shown, there is an inclination angle α between the extension direction of the air inlet 11 and the extension direction of the air outlet 12, and the inclination angle α may be between 45 degrees and 60 degrees. It is worth noting that the water tank W and the condenser H are also arranged at a position close to the air outlet 12 at an inclination angle α relative to the air inlet 11. Therefore, the water tank W and the condenser H also have a relatively large heat dissipation area.

[0037] In order to allow the airflow entering the air inlet 11 to effectively dissipate heat to the water tank W and the condenser H, there is a guide angle β between the extension direction of the air inlet 11 and the extension direction of the airflow guide surface 141 of the upper guide plate 14, which is greater than the inclination angle α. Therefore, the airflow can dissipate heat to the water tank W and the condenser H along the airflow guide surface 141 to the position of the air outlet 12. In this embodiment, the guide angle β can be between 60 degrees and 90 degrees, but is not limited thereto.

[0038] See also Figures 1 to 3 And with Figures 4 to 6 As shown, the airflow adjustment member 20 is disposed inside the air inlet 11 of the airflow guide cover 10 . Specifically, the airflow adjustment member 20 is configured to adjust the air flow rate and airflow direction through the air inlet 11 .

[0039] See also Figure 3 As shown, in this embodiment, the airflow adjustment member 20 may include a plurality of guide blades 21 arranged at intervals. The plurality of guide blades 21 are arranged to rotate and swing relative to the air inlet 11 to control the opening of the air inlet 11. For example, the plurality of guide blades 21 are arranged at intervals from top to bottom on the inner side of the air inlet 11, each guide blade 21 may be a rectangular thin sheet and have a wind guide surface 211, each guide blade 21 has a rotating shaft 212, and both ends of the rotating shaft 212 are rotatably fixed to opposite sides of the air inlet 11. The rotating shaft 212 is rotated to swing the guide blade 21 and control the rotation angle θ of the guide blade 21. However, the present invention is not limited to the above examples.

[0040] See also Figures 4 to 6 And with Figure 3 As shown, the rotation angle θ of each of the plurality of guide blades 21 can be between 90 degrees and 0 degrees (the wind guide surface 211 gradually moves toward the air inlet 11 along the rotation axis 212) to adjust the opening of the air inlet 11. Figure 4 And with Figure 3 As shown, when the rotation angle θ of each of the plurality of guide blades 21 is approximately 90 degrees, the wind guide surface 211 of each of the plurality of guide blades 21 is parallel to the opening direction of the air inlet 11 of the airflow guide cover 10, and the opening degree of the air inlet 11 is 100%. Figure 6 And with Figure 3As shown, when the rotation angle θ of each of the plurality of guide blades 21 is approximately 0 degrees, the air guide surface 211 of each of the plurality of guide blades 21 is perpendicular to the opening direction of the air inlet 11 of the airflow guide cover 10 and closes the air inlet 11, so that the opening of the air inlet 11 is 0%. When the rotation angle θ of each of the plurality of guide blades 21 is approximately 9 degrees, the opening of the air inlet 11 is 10%. When the rotation angle θ of each of the plurality of guide blades 21 is approximately 18 degrees, the opening of the air inlet 11 is 20% (as shown in FIG. 1 ). Figure 5 And with Figure 3 ). When the rotation angle θ of each of the plurality of guide blades 21 is approximately 45 degrees, the opening of the air inlet 11 is 50%. When the rotation angle θ of each of the plurality of guide blades 21 is approximately 63 degrees, the opening of the air inlet 11 is 70%. It is worth noting that as the rotation angle θ of the plurality of guide blades 21 increases, the intake air flow rate increases, and as the rotation angle θ of the plurality of guide blades 21 decreases, the air flow direction increases.

[0041] See also Figure 1 as well as Figure 2 As shown, in this embodiment, the heat exchange control device for electric vehicles can also include at least one exhaust portion 30, which is arranged on the lower guard plate. The lower guard plate is located at the bottom of the vehicle body, that is, below the front end of the vehicle body. Each at least one exhaust portion 30 includes an exhaust port 31 facing the airflow guide cover 10 and a rectifying channel 32. The rectifying channel 32 is formed by the lower guard plate being recessed in the direction of the inside of the electric vehicle, and the rectifying channel 32 gradually widens toward one end of the airflow guide cover 10 and surrounds the exhaust port 31. In this embodiment, the rectifying channel 32 can be a NACA duct. Therefore, after passing through the air outlet 12, the airflow can leave the interior of the vehicle body through at least one exhaust portion 30. Generally speaking, a fan is arranged on the outside of the air outlet 12 to assist the airflow to pass through the airflow channel 13. The arrangement of at least one exhaust portion 30 can allow the airflow to pass smoothly through the airflow channel 13 even if the fan is not operating.

[0042] Generally speaking, the heat dissipation requirement of the condenser H is higher than that of the water tank W, and the water tank W will be cooled or kept warm according to the requirements inside the electric vehicle. In the present embodiment, the condenser H is arranged and occupies the air outlet 12, and the water tank W is located between the condenser H and the air inlet 11 and close to the lower guide plate 15, and the water tank W occupies 1 / 3 to 1 / 2 of the air outlet 12. In other words, the heat dissipation surface of the water tank W is 1 / 3 to 1 / 2 of the heat dissipation surface of the condenser H. In some other embodiments, the heat dissipation area of ​​the water tank W can be obtained based on the loss calculation of the motor system, and the heat dissipation area of ​​the condenser H can be designed based on the heat dissipation requirements of the battery and the air conditioner, and the placement of the water tank W and the condenser H can be based on the correlation between the shape opening and the body structure to obtain the best air intake efficiency. However, the present invention is not limited to the above examples.

[0043] In this embodiment, the heat exchange control device for electric vehicles of the present invention may further include a driver, and the plurality of guide blades 21 of the airflow adjustment member 20 may be actuated and linked to the driver. In other words, the rotation shaft of each guide blade 21 may be actuated and linked to the driver. For example, the driver may be configured to drive the plurality of guide blades 21 to perform a rotation and swing operation according to a control instruction, and the control instruction may be issued by a main controller of the electric vehicle.

[0044] Therefore, see Figures 1 to 6 As shown, through the structural design of the airflow guide cover 10, the multiple guide blades 21 with adjustable rotation angle θ, and the setting positions of the water tank W and the condenser H, the heat dissipation ratio of the water tank W and the condenser H can be effectively allocated to improve the operating efficiency of the electric vehicle.

[0045] Second embodiment

[0046] See also Figure 7 as well as Figure 8 And with Figure 1 As shown, the second embodiment of the present invention provides a control method for a heat exchange control device for an electric vehicle, which may at least include the following steps S100 to S104. In step S100, at least one detector D senses at least one environmental parameter of the electric vehicle, and communicates at least one environmental parameter to the main controller C of the electric vehicle. In step S102, the main controller C determines a default heat exchange mode based on at least one environmental parameter, which meets the requirements of the current state of the electric vehicle. In step S104, the main controller C adjusts the airflow adjustment member 20 in the heat exchange control device of the electric vehicle based on the default heat exchange mode to assist in regulating the cooling of the water tank W and the condenser H of the electric vehicle. Among them, the heat exchange control device of the electric vehicle may be the heat exchange control device for the electric vehicle as described in the first embodiment, so the detailed structure of the heat exchange control device is not repeated here.

[0047] The control system configuration of the heat exchange control device of the electric vehicle can be roughly as follows: Figure 7 The main controller C is connected to the detector D and the driver M in communication, and the driver M is connected to the airflow adjustment member 20 of the heat exchange control device for electric vehicles. Figure 7 And with Figure 3 As shown, the driver M may be configured to adjust the rotation angle θ of the plurality of guide blades 21 by driving the rotation shafts 212 of the plurality of guide blades 21 (such as the airflow adjustment member 20 described in the first embodiment) to rotate.

[0048] See also Figure 8 And with Figure 3 As shown, in detail, in step S100, at least one environmental parameter may include but is not limited to: the external temperature of the electric vehicle, the motor temperature, the electronic control temperature, the battery pack temperature, the air conditioning line pressure, the vehicle speed, the passenger cabin air conditioning setting, etc. In step S102, the main controller C receives at least one environmental parameter to evaluate the cooling and heating requirements of the electric vehicle and determines the default heat exchange mode. In step S104, the main controller C sends a control instruction to the driver M according to the default heat exchange mode, and the driver M drives the guide blade 21 to rotate and swing according to the control instruction.

[0049] See also Figure 7 And with Figure 3 and Figure 4 As shown, for example, when the detector D senses that the electric vehicle is running at high speed in an external high temperature environment and the air conditioner in the passenger cabin is turned on, multiple detectors D transmit multiple environmental parameters to the main controller C. The main controller C analyzes that the water tank W and the condenser H need to be cooled quickly and significantly, and the main controller C determines that the default heat exchange mode is the first operation mode. The main controller C sends a control instruction to the driver M, and the driver M rotates and swings the multiple guide blades 21 of the air flow adjustment member 20 to the first operation position. Therefore, the wind guide surface 211 of each of the multiple guide blades 21 is parallel to the opening direction of the air inlet 11 of the air flow guide cover 10 (that is, the rotation angle θ of each of the multiple guide blades 21 is about 90 degrees), and the opening of the air inlet 11 is 100%, so as to directly and quickly perform heat exchange on the water tank W and the condenser H.

[0050] See also Figure 7 And with Figure 3 and Figure 6As shown, when the detector D senses that the electric vehicle is running in an external low-temperature environment and the passenger cabin heating air conditioner is turned on, multiple detectors D transmit multiple environmental parameters to the main controller C. The main controller C analyzes that the water tank W and the condenser H need to be kept warm to increase the system heating speed, and the main controller C determines that the default heat exchange mode is the second operation mode. The main controller C sends a control instruction to the driver M, and the driver M rotates and swings the multiple guide blades 21 of the airflow adjustment member 20 to the second operation position. Therefore, the wind guide surface 211 of each of the multiple guide blades 21 is perpendicular to the opening direction of the air inlet 11 of the airflow guide cover 10 and closes the air inlet 11 (that is, the rotation angle θ of each of the multiple guide blades 21 is about 0 degrees), so that the opening of the air inlet 11 is 0%, so as to avoid the airflow from exchanging heat with the water tank W and the condenser H.

[0051] See also Figure 7 And with Figure 3 and Figure 5 As shown, for example, when multiple detectors D transmit multiple environmental parameters to the main controller C, and the main controller C analyzes that the cooling of the water tank W needs to be avoided and the condenser H needs to be slightly cooled, the main controller C determines that the default heat exchange mode is the third operation mode. The main controller C sends a control instruction to the driver M, and the driver M rotates and swings the multiple guide blades 21 of the airflow adjustment member 20 to the third operation position. Therefore, the rotation angle θ of each of the multiple guide blades 21 is approximately 0 degrees to 27 degrees, and the opening of the air inlet 11 is between 0% and 30%. That is, the airflow will avoid the direction toward the water tank W and perform heat exchange on the condenser H along the airflow guide surface 141 of the upper guide plate 14.

[0052] See also Figure 7 And with Figure 3 As shown, for example, when multiple detectors D transmit multiple environmental parameters to the main controller C, and the main controller C analyzes that the water tank W and the condenser H need to be slightly cooled, the main controller C determines that the default heat exchange mode is the fourth operation mode. The main controller C sends a control instruction to the driver M, and the driver M rotates and swings the multiple guide blades 21 of the airflow adjustment member 20 to the fourth operation position. Therefore, the rotation angle θ of each of the multiple guide blades 21 is approximately 27 degrees to 54 degrees, and the opening of the air inlet 11 is between 30% and 60%. That is, the airflow will be slightly toward the direction of the water tank W, and the condenser H will be heat exchanged along the airflow guide surface 141 of the upper guide plate 14.

[0053] See also Figure 7 And with Figure 3As shown, for example, when multiple detectors D transmit multiple environmental parameters to the main controller C, and the main controller C analyzes that the water tank W and the condenser H need to be cooled significantly, the main controller C determines that the default heat exchange mode is the fifth operation mode. The main controller C sends a control instruction to the driver M, and the driver M rotates and swings the multiple guide blades 21 of the airflow adjustment member 20 to the fifth operation position. Therefore, the rotation angle θ of each of the multiple guide blades 21 is approximately 54 degrees to 81 degrees, and the opening of the air inlet 11 is between 60% and 90%. That is, the airflow will be partially directed toward the water tank W, and heat exchange will be performed on the condenser H along the airflow guide surface 141 of the upper guide plate 14.

[0054] However, the above example is only one feasible embodiment and is not intended to limit the present invention.

[0055] Advantageous Effects of Embodiments

[0056] One of the beneficial effects of the present invention is that the heat exchange control device and control method for an electric vehicle provided by the present invention can effectively adjust the heat dissipation ratio of the water tank and the condenser through the technical scheme of "a water tank and a condenser are provided in the air flow channel and close to the air outlet" and "an air flow adjustment component is provided on the inner side of the air inlet of the air flow guide cover, and the air flow adjustment component is configured to adjust the air intake flow and airflow direction through the air inlet" so as to meet the cooling and heating requirements of the heat pump system for the three-electric system and the cabin air conditioning under different temperature environments according to the driving conditions of the electric vehicle.

[0057] Furthermore, by tilting the air outlet, water tank and condenser of the airflow guide cover of the present invention relative to the air inlet, the heat dissipation surface of the water tank and the condenser can be increased, and the heat dissipation ratio of the water tank and the condenser can be effectively adjusted.

[0058] In addition, by adjusting the opening of the air inlet and the airflow direction through the rotation angle of the plurality of guide vanes, it is possible to avoid an increase in energy consumption of the electric vehicle due to overcooling of the water tank and / or the condenser.
