Description

Technical Field

[0001] The present disclosure relates to the technical field of automobile ventilation and heat dissipation, and in particular to a front-end cooling module of an automobile and an automobile. Background Art

[0002] The front-end cooling module is a device or system located at the front end of the car for dissipating heat for the entire vehicle. It mainly includes a grille and a heat exchanger, wherein the grille is arranged at the front face of the car, and the heat exchanger is arranged in the front engine compartment of the car and is close to the grille.

[0003] The heat exchanger is generally an air-cooled heat exchanger, which includes not only a heat dissipation core for circulating the cooling medium, but also a fan, which is fixed at the rear of the heat dissipation core.

[0004] In application, the grille has an opening, which serves as an air inlet of the front-end cooling module, and the air outlet of the fan serves as the air outlet of the front-end cooling module. However, since the fan is arranged behind the grille along with the heat exchanger, the air outlet of the front-end cooling module can only be directed toward the rear of the front cabin, resulting in a relatively single arrangement of the air outlet direction of the front-end cooling module. Utility Model Content

[0005] The present disclosure provides a front-end cooling module of an automobile and an automobile. The front-end cooling module is applied in the automobile, and the direction of the air outlet of the front-end cooling module can be flexibly arranged according to demand. In addition, the front-end cooling module is applied in new energy vehicles and has higher heat dissipation performance.

[0006] In a first aspect, according to the present disclosure, a front-end cooling module of an automobile is provided, the front-end cooling module comprising a heat exchanger, a fan, an air guide cover and a grille;

[0007] The grille is located at the front face of the vehicle, the heat exchanger, the fan and the air shroud are all located in the front cabin of the vehicle, the heat exchanger is close to the grille, the fan is located behind the heat exchanger away from the grille, and the air shroud is arranged between the heat exchanger and the fan;

[0008] The air guide cover is used to form an air duct between the heat exchanger and the fan, the opening of the grille serves as an air inlet of the air duct, and the air outlet of the fan serves as an air outlet of the air duct.

[0009] In the solution shown in the present disclosure, the heat exchanger and the fan are decoupled in the assembly method and are no longer assembled as a whole in the front cabin. The position of the fan in the front cabin determines the air outlet of the air duct. Therefore, after the fan is decoupled from the heat exchanger, its layout in the front cabin is more flexible, so that the direction of the air outlet of the front-end cooling module can be flexibly set according to needs and expectations, so that the arrangement of the air outlet direction of the front-end cooling module is no longer single.

[0010] In a possible implementation, in the height direction of the vehicle, a relative difference between the size of the heat exchanger and the size of the opening area of ​​the grille is less than or equal to 20%;

[0011] A relative difference between a size of the heat exchanger and a size of an opening area of ​​the grille in a width direction of the vehicle is less than or equal to 20%.

[0012] In the scheme shown in the present disclosure, the size of the heat exchanger along the height direction of the vehicle body is equivalent to the size of the opening area of ​​the grille along the height direction of the vehicle body, and the size of the heat exchanger along the width direction of the vehicle body is equivalent to the size of the opening area of ​​the grille along the width direction of the vehicle body. Therefore, the cold air entering from the grille can pass through most of the area of ​​the heat exchanger, so that the cooling air is evenly distributed on the heat exchanger, thereby improving the heat dissipation performance of the heat exchanger.

[0013] Once the ventilation and heat dissipation effects of new energy vehicles are improved, the fan will not need to run at a higher speed, thereby reducing the energy consumption of ventilation and heat dissipation.

[0014] In a possible implementation, the air outlet of the air duct faces one or more of the following directions:

[0015] The outside of the front wheel of the vehicle, the brake disc of the front wheel of the vehicle, the rear of the front cabin of the vehicle, and the bottom of the front cabin of the vehicle.

[0016] In the scheme shown in the present invention, the air outlet of the air duct is toward the outside of the front wheel, which is beneficial to reducing the wind resistance at the front wheel tire. The air outlet of the air duct is toward the rear or bottom or rear-lower part of the front engine compartment, which is also beneficial to reducing the wind resistance at the front wheel tire. The air outlet of the air duct is toward the brake disc of the front wheel to dissipate the heat of the brake disc and make secondary use of the wind entering the front engine compartment.

[0020] In the solution shown in the present disclosure, in the solution where one or more fans are arranged behind the heat exchanger, an air guide cover is arranged between the first end of the heat exchanger and the first end of the fan closest to the first end of the heat exchanger, and an air guide cover is arranged between the second end of the heat exchanger and the second end of the fan closest to the second end of the heat exchanger. The first end of the heat exchanger and the first end of the fan both refer to the end close to the left front wheel, and the second end of the heat exchanger and the second end of the fan both refer to the end close to the right front wheel.

[0021] In one possible implementation, there are multiple fans, some of which are located at the first end of the heat exchanger with air outlets facing the outside of the left front wheel of the vehicle, and another part of the fans are located at the second end of the heat exchanger with air outlets facing the outside of the right front wheel of the vehicle.

[0022] The first end of the heat exchanger is also the end close to the left front wheel, and the second end of the heat exchanger is also the end close to the right front wheel.

[0023] In the solution shown in the present disclosure, a part of the fans are arranged near the left front wheel, and the air outlets thereof are directed toward the outside of the left front wheel, so that the air outlets of the air duct can be directed toward the outside of the left front wheel. Another part of the fans are arranged near the right front wheel, and the air outlets thereof are directed toward the outside of the right front wheel, so that the air outlets of the air duct can be directed toward the outside of the right front wheel.

[0025] In the solution shown in the present disclosure, a part of the fans are arranged near the left front wheel, and the air outlets thereof are directed toward the brake disc of the left front wheel, so that the air outlets of the air ducts can be directed toward the brake disc of the left front wheel. Another part of the fans are arranged near the right front wheel, and the air outlets thereof are directed toward the brake disc of the right front wheel, so that the air outlets of the air ducts can be directed toward the brake disc of the right front wheel.

[0044] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0045] The present embodiment relates to a car, which may specifically be a new energy car. A new energy car is a car different from a traditional fuel car, and generally refers to a car that uses unconventional vehicle fuel as a power source, wherein unconventional vehicle fuel mainly refers to fuels other than gasoline and diesel.

[0046] Whether it is a new energy vehicle or a fuel vehicle, a front-end cooling module will be arranged at the front end, wherein the front-end cooling module mainly includes a grille and a heat exchanger, wherein the grille is arranged at the front face of the vehicle, and the heat exchanger is installed in the front engine compartment of the vehicle, close to the grille, and the grille serves as the air inlet of the front-end cooling module, wherein the heat exchanger is a heat exchanger with a fan integrated at the rear.

[0047] For traditional fuel vehicles, the heat generated is relatively large, and combustion aid is also required, so the grille generally includes an upper grille and a lower grille. The upper grille is generally arranged in the upper half of the front face, or in the center of the front face, and the lower grille is generally arranged in the lower half of the front face, below the air intake grille.

[0048] Therefore, for traditional fuel vehicles, in order to allow the wind entering from the upper grille and the wind entering from the lower grille to pass through the heat exchanger, the size of the heat exchanger will be made larger to cover the upper grille and the lower grille.

[0049] As for new energy vehicles, since they do not generate much heat, they do not need so many grilles. Moreover, unnecessary grilles placed on the front of the car will increase wind resistance. Therefore, for new energy vehicles, the upper grille is generally removed and only the lower grille is retained. Among them, the upper grille can be removed in one way, that is, the upper grille is no longer arranged on the front face, so that the upper grille cannot be seen from the appearance. Another way is that although there is an upper grille on the appearance, the upper grille does not have an opening. This upper grille without an opening is not a grille in the strict sense. Therefore, in the text, unless otherwise specified, the grille refers to a grille with an opening.

[0050] As for new energy vehicles, compared with fuel vehicles, although the grille of its front-end module has changed, the heat exchanger remains unchanged. For example, the heat exchanger used is the same as that of fuel vehicles. Then, when this front-end cooling module is used in new energy vehicles, there are at least the following problems.

[0051] Firstly, since the heat exchanger is integrated with a fan, the air outlet of the front-end cooling module can only face backward or downward, resulting in a single air outlet direction and poor application flexibility. Moreover, the air outlet faces backward or downward, resulting in relatively large wind resistance of the car.

[0052] Secondly, because the heat exchanger with the same size as the grille of a fuel vehicle is applied to a new energy vehicle, and the grille size of a new energy vehicle is much smaller than that of a fuel vehicle, this will cause the heat exchanger applied to the new energy vehicle to be far from matching the grille of the new energy vehicle, causing a deviation in the heat dissipation performance of the new energy vehicle. For example, the wind entering from the grille can only pass through the area of ​​the heat exchanger facing the grille, and the cooling wind is difficult to enter the area of ​​the heat exchanger not facing the grille, causing the wind entering from the grille to be difficult or impossible to evenly pass through various positions of the heat exchanger, thereby causing a deviation in the heat dissipation performance of the new energy vehicle.

[0053] To this end, this embodiment provides a front-end cooling module for an automobile, such as Figure 1 and Figure 2 As shown, the front-end cooling module includes a heat exchanger 1, a fan 2 and a grille 4. Figure 1 As shown, the grille 4 is arranged at the front face, for example, it can be arranged at the lower half of the front face, it can also be arranged at the upper half of the front face, and it can also be arranged at the middle part of the front face. The figure shows an example of being arranged at the lower half of the front face.

[0054] In one example, the grille 4 may be a row of grilles arranged along the width direction of the vehicle body, or may be multiple rows of grilles. If there are multiple rows of grilles, the multiple rows of grilles are arranged in sequence along the height direction of the vehicle body. The number of grilles 4 is not limited in this embodiment.

[0055] It should be pointed out that the directional nouns front and back, left and right, and up and down involved in the article, as well as the directional nouns front and back, left and right, and up and down that will be mentioned below, unless otherwise specified, are based on the length direction of the car as the front and back direction, also recorded as the X-axis direction, the width direction of the car as the left and right direction, also recorded as the Y-axis direction, and the height direction of the car as the up and down direction or vertical direction, also recorded as the Z-axis direction.

[0056] refer to Figure 2 As shown, the heat exchanger 1 and the fan 2 are both arranged in the front cabin of the vehicle, for example, the heat exchanger 1 is close to the grille 4 and the fan 2 is arranged behind the heat exchanger 1 .

[0057] In one example, the heat exchanger 1 and the fan 2 are no longer fixed together, and both are arranged separately in the front cabin. Then, in order to allow the cooling air to flow between the heat exchanger 1 and the fan 2, accordingly, Figures 4 to 6 As shown, the front-end cooling module further includes an air guide cover 3 , which is also located in the front cabin and arranged between the heat exchanger 1 and the fan 2 , forming an air duct 5 between the heat exchanger 1 and the fan 2 .

[0058] The opening of the grille 4 serves as an air inlet of the air duct 5 , and the air outlet of the fan 2 serves as an air outlet of the air duct 5 .

[0059] In this way, under the action of the air guide cover 3, the cold air entering from the grille 4 passes through the heat exchanger 1, absorbs the heat of the heat exchanger 1, and the wind absorbing the heat becomes hot air and is discharged through the fan 2.

[0060] Among them, cold air and hot air are two relative concepts, and the temperature range of cold air and the temperature range of hot air are not limited.

[0061] In one example, the heat exchanger 1 and the fan 2 are decoupled in the assembly method and are no longer assembled as a whole in the front cabin, and the position of the fan 2 in the front cabin determines the air outlet of the air duct 5. Therefore, after the fan 2 is decoupled from the heat exchanger 1, the arrangement position in the front cabin is more flexible, so that the direction of the air outlet of the front-end cooling module is also more flexible.

[0062] In this embodiment, not only are the heat exchanger 1 and the fan 2 decoupled, but the size of the heat exchanger 1 is also designed based on the size of the grille 4, so that the size of the heat exchanger 1 is equal to or nearly equal to the size of the grille 4. In this way, the cold air entering the air duct 5 from the grille 4 can pass through the heat exchanger 1 evenly, so that the cooling air is evenly distributed on the heat exchanger 1, so as to improve the heat dissipation performance of the heat exchanger 1.

[0063] In one example, the size of the heat exchanger 1 is equal to or nearly equal to the size of the grille 4. For example, the size of the heat exchanger 1 along the vehicle body height direction is equal to or nearly equal to the size of the opening area of ​​the grille 4 along the vehicle body height direction, and the size of the heat exchanger 1 along the vehicle body width direction is equal to or nearly equal to the size of the opening area of ​​the grille 4 along the vehicle body width direction.

[0064] It should be noted that if the absolute value of the relative difference between the size of the heat exchanger 1 along the height direction of the vehicle body and the size of the opening area of ​​the grille 4 along the height direction of the vehicle body is less than or equal to 20%, the two can be considered equal. Similarly, if the absolute value of the relative difference between the size of the heat exchanger 1 along the width direction of the vehicle body and the size of the opening area of ​​the grille 4 along the width direction of the vehicle body is less than or equal to 20%, the two can be considered equal.

[0065] In one example, the heat exchanger 1 can be placed vertically in the front engine compartment, or can be arranged in an inclined state in the front engine compartment. If the heat exchanger 1 is placed vertically in the front engine compartment, then the size of the heat exchanger 1 along the vehicle height direction is the height of the heat exchanger 1 itself. If the heat exchanger 1 is arranged in an inclined manner in the front engine compartment, then the size of the heat exchanger 1 along the vehicle height direction is the component of the height of the heat exchanger 1 itself in the vertical direction.

[0066] In one example, the size of the heat exchanger 1 is comparable to the size of the grille 4. Compared with a conventional heat exchanger, since the area of ​​the heat exchanger 1 of this embodiment is reduced, the heat dissipation performance of the heat exchanger 1 of this embodiment may be sacrificed. However, the sacrifice in heat dissipation performance can be compensated by increasing the number of heat exchangers 1, thereby achieving heat dissipation performance comparable to or even better than that of a conventional heat exchanger.

[0067] Therefore, there are multiple heat exchangers 1, and the multiple heat exchangers 1 are arranged in the front engine compartment and arranged in sequence along the length direction of the vehicle body.

[0068] In one example, in a scheme where there are multiple heat exchangers 1, the size of the heat exchanger 1 is comparable to the size of the grille 4. The size of the heat exchanger 1 closest to the grille 4 can be comparable to the size of the grille 4, or the size of any heat exchanger 1 can be comparable to the size of the grille 4.

[0069] In one example, in a scheme where there are multiple heat exchangers 1, the size of the heat exchanger 1 is equivalent to the size of the grille 4. Alternatively, the size of the heat exchanger 1 closest to the grille 4 in the vehicle height direction is equivalent to the size of the grille 4 in the vehicle height direction, and the size of the heat exchanger 1 closest to the grille 4 in the vehicle width direction is equivalent to the size of the grille 4 in the vehicle width direction. The size of other heat exchangers 1 in the vehicle height direction is equivalent to the size of the grille 4 in the vehicle height direction, but the size of other heat exchangers 1 in the vehicle width direction may be larger than the size of the grille 4 in the vehicle height direction.

[0070] It should be pointed out that in the above discussion of the size of the heat exchanger 1 and the size of the grille 4, the size of the grille 4 refers to the size of the opening area of ​​the grille 4, for example, it refers to the size of the opening area of ​​the grille 4 in the direction along the height of the vehicle body and the size in the direction along the width of the vehicle body.

[0071] As described above, since the heat exchanger 1 and the fan 2 are no longer fixed to each other, the two are decoupled and arranged in the front cabin. Therefore, the direction of the air outlet of the air duct 5 formed between the heat exchanger 1 and the fan 2 is more flexible.

[0072] For example, the air outlet of the air duct 5 is toward the outside of the front wheel of the car. Figure 4 As shown, the air outlet of one air duct 5 faces the outer side of the left front wheel of the automobile, and the air outlet of the other air duct 5 faces the outer side of the right front wheel.

[0073] In order to achieve Figure 4 The air outlet direction shown is shown in Figure 4 As shown, there are multiple fans 2, a part of the fans 2 are close to the left front wheel, and the air outlets are facing the outside of the left front wheel, and another part of the fans 2 are close to the right front wheel, and the air outlets are facing the outside of the right front wheel.

[0074] In order to prevent the wind entering the front cabin from running around, it should pass through the heat exchanger 1 as much as possible and be discharged through the air outlet. Figure 4 As shown, there are multiple air guide covers 3, and an air guide cover 3 is arranged between the first end of the heat exchanger 1 and the fan 2 at the left front wheel ( Figure 4 The air guide 3a in the heat exchanger 1 is arranged between the second end of the heat exchanger 1 and the fan 2 at the right front wheel. Figure 4 Moreover, an air guide 3 ( Figure 4 The first position of the heat exchanger 1 and the fan 2 at the right front wheel are also provided with an air guide 3 ( Figure 4The first position of the heat exchanger 1 is any position between the first end and the second end of the heat exchanger 1, for example, it can be the middle position of the heat exchanger 1.

[0075] So, reference Figure 4 As shown, the left half of the heat exchanger 1, the air guide cover 3a, the air guide cover 3b and the fan 2 at the left front wheel form an air duct 5, and the air outlet of the air duct 5 faces the outside of the left front wheel. The right half of the heat exchanger 1, the air guide cover 3c, the air guide cover 3d and the fan 2 at the right front wheel form another air duct 5, and the air outlet of the air duct 5 faces the outside of the right front wheel.

[0076] Continue to refer Figure 4 As shown, the cold air entering the front engine room through the grille 4 passes through the heat exchanger 1 and is discharged to the outside of the left front wheel under the action of the fan 2 at the left front wheel, and is discharged to the outside of the right front wheel under the action of the fan 2 at the right front wheel. This scheme of discharging the hot air passing through the heat exchanger 1 to the outside of the left front wheel and to the outside of the right front wheel helps to reduce the wind resistance near the left front wheel tire and the wind resistance near the right front wheel tire.

[0077] For another example, the air outlet of the air duct 5 is toward the outside of the front wheel of the car. Figure 5 As shown, the air outlet of one air duct 5 faces the brake disc of the left front wheel of the vehicle, and the air outlet of the other air duct 5 faces the brake disc of the right front wheel.

[0078] In order to achieve Figure 5 The air outlet direction shown is shown in Figure 5 As shown, there are multiple fans 2, a part of the fans 2 are close to the left front wheel, and the air outlets are facing the brake disc of the left front wheel, and another part of the fans 2 are close to the right front wheel, and the air outlets are facing the brake disc of the right front wheel.

[0079] In order to prevent the wind entering the front cabin from running around, it should pass through the heat exchanger 1 as much as possible and be discharged through the air outlet. Figure 5 As shown, there are multiple air guide covers 3, and an air guide cover 3 is arranged between the first end of the heat exchanger 1 and the fan 2 at the left front wheel ( Figure 5 The air guide 3a in the heat exchanger 1 is arranged between the second end of the heat exchanger 1 and the fan 2 at the right front wheel. Figure 5 Moreover, an air guide 3 ( Figure 5 The first position of the heat exchanger 1 and the fan 2 at the right front wheel are also provided with an air guide 3 ( Figure 5 The first position of the heat exchanger 1 is any position between the first end and the second end of the heat exchanger 1, for example, it can be the middle position of the heat exchanger 1.

[0080] So, reference Figure 5 As shown, the left half of the heat exchanger 1, the air guide 3a, the air guide 3b and the fan 2 at the left front wheel form an air duct 5, and the air outlet of the air duct 5 faces the brake disc of the left front wheel. The right half of the heat exchanger 1, the air guide 3c, the air guide 3d and the fan 2 at the right front wheel form another air duct 5, and the air outlet of the air duct 5 faces the brake disc of the right front wheel.

[0081] Continue to refer Figure 5 As shown, the cold air entering the front engine compartment through the grille 4 passes through the heat exchanger 1 and is discharged to the brake disc of the left front wheel under the action of the fan 2 at the left front wheel, and is discharged to the brake disc of the right front wheel under the action of the fan 2 at the right front wheel. This solution of the air passing through the heat exchanger 1 and being discharged to the brake disc of the left front wheel and the brake disc of the right front wheel can be reused and can dissipate heat for the brake disc.

[0082] In other examples, the air outlet of the air duct 5 may be directed toward the outside of the front wheels and the brake disc. For example, the wind discharged from the air outlet of the air duct 5 not only flows toward the outside of the left front wheel, but also flows toward the brake disc of the left front wheel.

[0083] For example, Figure 6 As shown, the air outlet of the air duct 5 is toward the rear of the front cabin of the car, or toward the bottom of the front cabin of the car, or toward the rear and lower part of the front cabin of the car.

[0084] In order to achieve Figure 6 The air outlet direction shown is shown in Figure 6 As shown, the number of fans 2 can be one, which is located directly behind the heat exchanger 1. In the solution where the number of fans 2 is one, in order to allow the wind entering the front cabin to pass through the heat exchanger 1, the first method can be that the distance between the fan 2 and the heat exchanger 1 is slightly farther, so that the suction range of the fan 2 can be relatively large, so that the cold air entering from the grille 4 can pass through the heat exchanger 1. The second method can be that the size of the fan 2 along the width direction of the vehicle body is equivalent to the size of the heat exchanger 1 along the width direction of the vehicle body, so that when the fan 2 and the heat exchanger 1 are relatively close, the cold air entering from the grille 4 can pass through the heat exchanger 1. Moreover, in the second implementation method, it is also beneficial to reduce the space occupied by the front cooling module in the front cabin, and the arrangement of the heat exchanger 1 and the fan 2 will not affect the installation of other devices in the front cabin.

[0085] In order to achieve Figure 6In the air outlet orientation shown, the number of fans 2 can also be multiple, and multiple fans 2 are arranged behind the heat exchanger 1. In the scheme where the number of fans 2 is multiple, the total size of the multiple fans 2 along the width direction of the vehicle body is equivalent to the size of the heat exchanger 1 along the width direction of the vehicle body. In this way, when the fans 2 and the heat exchanger 1 are close to each other, the cold air entering from the grille 4 can pass through the heat exchanger 1. Moreover, this arrangement is conducive to reducing the space occupied by the front cooling module in the front cabin, and the arrangement of the heat exchanger 1 and the fans 2 will not affect the installation of other devices in the front cabin.

[0086] It can be seen that in the solution where the air outlet of the air duct 5 faces the rear, bottom or rear bottom of the front engine compartment of the automobile, the number of the fans 2 can be one or more.

[0087] Similarly, in order to prevent the wind entering the front cabin from running around, it should pass through the heat exchanger 1 as much as possible and be discharged through the air outlet. Accordingly, in the solution where the number of fans 2 is one, refer to Figure 6 As shown, an air guide 3 is arranged between the first end of the heat exchanger 1 and the first end of the fan 2 ( Figure 6 The air guide hood 3e in the heat exchanger 1 is arranged between the second end of the heat exchanger 1 and the second end of the fan 2. Figure 6 In the scheme where the number of fans 2 is multiple, an air guide 3 is arranged between the first end of the heat exchanger 1 and the first end of the closest fan 2, and an air guide 3 is arranged between the second end of the heat exchanger 1 and the second end of the closest fan 2.

[0088] The solution in which the air outlet of the air duct 5 is oriented toward the rear, bottom, or rear lower part of the front engine compartment of the automobile is also beneficial to reducing the wind resistance of the front tires because the wind discharged from the air duct 5 does not blow toward the wheels.

[0089] In another example, the air outlet direction of the front-end cooling module can be a combination of at least two of the above-mentioned methods, such as the front-end cooling module includes multiple air ducts, the air outlets of some air ducts are directed toward the outside of the front wheels, the air outlets of another part of the air ducts are directed toward the brake discs of the front wheels, and the air outlets of another part of the air ducts are directed toward the rear of the front engine compartment.

[0090] It should be pointed out that Figures 4 to 6 The arrows in the middle indicate the direction of wind flow. The air duct 5 between the heat exchanger 1 and the fan 2 is not only surrounded by the heat exchanger 1, the fan 2 and the air guide 3, but also includes the bottom plate of the front cabin and the engine cover. The closed area surrounded by these components forms the air duct 5, and there may be a gap between two adjacent components. However, the smaller the gap, the more conducive it is for the airflow to enter through the grille 4 and be discharged from the air outlet of the fan 2, and the more conducive it is to improve the heat dissipation performance of the heat exchanger 1.

[0091] It should be pointed out that in the solution with multiple heat exchangers 1 , an air guide hood 3 is arranged between the first end of the heat exchanger 1 and the fan 2 , which specifically means that the first ends of all the heat exchangers 1 are in contact with the air guide hood 3 .

[0092] In one example, when arranging the position of the fan 2, the fan 2 can be placed as close to the heat exchanger 1 as possible. The closer the fan 2 is to the heat exchanger 1, the smaller the space occupied by the front cooling module in the car, which is more conducive to the arrangement of other devices in the front cabin of the car.

[0093] The above is an introduction to the direction of the air outlet of the air duct and the arrangement position of the fan 2. The following will introduce the type of the fan 2 and the characteristics of the heat exchanger 1 respectively.

[0094] In an example, the type of the fan 2 may be an axial flow fan, a centrifugal fan, or a cross-flow fan, or, if there are multiple fans 2, the multiple fans 2 may include one or more of an axial flow fan, a centrifugal fan, and a cross-flow fan. In this embodiment, the type of the fan 2 is not limited, and it can be flexibly selected according to the needs in the application.

[0095] In one example, the heat exchanger 1 may be an air-cooled heat exchanger, and the cooling medium circulating inside the heat exchanger may be a liquid, a gas, or a two-phase substance including a liquid and a gas.

[0096] like Figure 3 The schematic diagram of the structure of a single heat exchanger 1 is shown. Figure 3 As shown, the heat exchanger 1 mainly includes a heat dissipation core 10, a first header 11, a second header 12, an inlet 13 and an outlet 14 in terms of structure, wherein the inlet 13 is connected to the first header 11, the first header 11 is connected to the second header 12 through the heat dissipation core 10, and the second header 12 is connected to the outlet 14, so that the cooling medium circulates in the heat exchanger 1. The inlet 13 and the outlet 14 are connected by a pipeline, and the pipeline is distributed near the device to be cooled to dissipate heat for the device to be cooled.

[0097] In application, the cooling medium in the pipe connected to the inlet 13 absorbs the heat of the device to be cooled. The cooling medium with a relatively high temperature enters the heat exchanger 1 through the inlet 13. The cold air blown to the heat exchanger 1 cools the cooling medium flowing in the heat exchanger 1. The cooled cooling medium flows out through the outlet 14 and continues to cool the device to be cooled.

[0098] It should be noted that the flow direction of the cooling medium in the heat exchanger 1 can be any one of from top to bottom, from bottom to top, from left to right and from right to left, or any combination of multiple of them.

[0099] In the disclosed embodiment, the heat exchanger and the fan are decoupled in the assembly method and are no longer assembled as a whole in the front cabin. The position of the fan in the front cabin determines the air outlet of the air duct. Therefore, after the fan is decoupled from the heat exchanger, its arrangement position in the front cabin is more flexible, and thus the direction of the air outlet of the front-end cooling module is also more flexible.

[0100] Furthermore, in the disclosed embodiment, the size of the heat exchanger 1 is designed according to the size of the grille 4, so that the size of the heat exchanger 1 is equal to or nearly equal to the size of the grille 4, so that the cold air entering the air duct 5 from the grille 4 can pass through most areas of the heat exchanger 1, so that the cooling air is evenly distributed on the heat exchanger 1, thereby improving the heat dissipation performance of the heat exchanger 1. Once the ventilation and heat dissipation effect of the new energy vehicle is improved, the fan does not need to run at a higher speed, thereby reducing the energy consumption of ventilation and heat dissipation.
