Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a heat exchange component, a vehicle, and a control method for the heat exchange component. Background Art

[0002] In the related art, the air scoop of the vehicle is opened at a fixed angle to discharge air through the heat exchanger. Even when the vehicle is running at a high altitude, the opening angle of the air scoop of the vehicle cannot be adjusted.

[0003] However, due to different driving conditions of the vehicle, in some scenarios the air volume output at this fixed angle is already greater than the air volume required for cooling and heat exchange. Since the larger the opening angle of the air guide hood, the greater the wind resistance, in this case, there will be greater wind resistance, which is not conducive to the endurance of the entire vehicle.

The fan can inhale natural wind from the outside, and then blow the wind from the air inlet into the air guide.

In other words, the amount of air blown onto the heat exchanger can be adjusted, rather than a fixed amount. In this way, when a smaller amount of air is needed, the opening of the air outlet can be reduced, so that the amount of air blown onto the heat exchanger is reduced, which also reduces wind resistance.

[0106] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0107] In related technologies, a vehicle's air scoop can only be opened at a fixed angle to release air through the heat exchanger. Even when the vehicle is operating at full height, the scoop's opening angle cannot be adjusted. However, due to varying vehicle driving conditions, in some scenarios, the air volume released at this fixed angle exceeds the required air volume for cooling and heat exchange. Since a larger opening angle of the scoop increases wind resistance, this creates significant wind resistance, negatively impacting the vehicle's range.

[0108] The larger the opening angle of the air guide, the greater the wind resistance. There may be many reasons for this. The following are some of the reasons:

[0109] First, the large opening angle of the air guide hood results in a large windward area of the air guide hood, which may lead to increased wind resistance.

[0110] Secondly, when the opening angle of the wind scoop is small, the opening area is small, and when the opening angle of the wind scoop is large, the opening area is large. Compared with the case where the wind scoop is opened at a large angle, when the wind scoop is opened at a small angle, the proportion of the airflow passing through the wind scoop is larger. The wind scoop generally has a streamlined structure, which means that the airflow will pass through a larger proportion of the streamlined structure, thereby reducing wind resistance. Conversely, compared with the case where the wind scoop is opened at a small angle, when the wind scoop is opened at a large angle, the proportion of the airflow passing through the wind scoop is smaller, which means that the airflow will pass through a smaller proportion of the streamlined structure, thereby increasing wind resistance.

[0111] Thirdly, the larger the opening angle of the air scoop, the greater the amount of air blown from the air scoop to the internal components of the vehicle. Since the direction of the wind blown from the air scoop to the internal components of the vehicle is opposite to the direction of travel of the vehicle, the wind resistance may increase.

[0112] Fourthly, when the air scoop opens at a large angle, the amount of air blown toward components inside the vehicle by the air scoop increases, which may cause changes in the pressure inside the vehicle cabin, resulting in increased circulation resistance inside the car, which may in turn increase wind resistance.

[0113] According to a first aspect of the present application, the present disclosure provides a heat exchange assembly, which is applied to a vehicle and can be used to perform thermal management for the vehicle.

[0114] In some embodiments, reference Figure 1 The heat exchange component 1 of the present application can be arranged opposite to the vehicle's air intake grille 510. In this way, external air (or natural wind) can enter the vehicle through the air intake grille 510 and exchange heat with the heat exchange component 1. Figure 1 The middle arrow represents the outside air (or natural wind).

[0115] Reference Figure 2 The heat exchange component 1 includes a fan 300, an air guide and a heat exchanger 400. The fan has an air outlet; the air guide is provided with an air inlet 101 and an air outlet 102 that are connected to each other. The air inlet 101 is used for air intake. The air inlet 101 is connected to the air outlet of the fan. The fan 300 can inhale natural wind from the outside and then blow the wind into the air guide through the air inlet 101.

[0116] Since the air guide is provided with an air outlet 102, the air blown out of the air outlet of the fan enters the air guide from the air inlet 101 and is blown toward the heat exchanger through the air outlet 102 through the air guide. The fan 300 can be a blower, a fan, etc. In some examples, the fan 300 can be a blower.

[0117] The opening of the air outlet 102 is adjustable to change the amount of air blown toward the heat exchanger 400. In other words, the amount of air reaching the heat exchanger 400 is adjustable, rather than being fixed. Therefore, when a lower air volume is required, the opening of the air outlet 102 can be reduced, thereby reducing the amount of air reaching the heat exchanger 400 and, in turn, reducing wind resistance.

[0118] The air guide can cooperate with the heat exchanger 400. In some examples, the air outlet 102 of the air guide can be directed toward at least part of the heat exchanger 400, so that the air guide can blow air toward the heat exchanger 400, allowing the air to pass through the heat exchanger 400.

[0119] The heat exchange assembly 1 can be used to cool the vehicle or to heat the vehicle. This application is described in the context of the heat exchange assembly being used to cool the vehicle.

[0120] The heat exchange assembly is used to cool the vehicle. When the outside temperature is low or the vehicle is traveling at a high speed, natural wind can remove more heat from the vehicle, and the vehicle's demand for the fan's air volume is relatively low. In this case, the opening of the air outlet 102 can be reduced. As the opening of the air outlet 102 is reduced, the air volume discharged from the air outlet 102 decreases, reducing the windward area of the air guide cover and reducing wind resistance.

[0121] Please combine Figure 2 In some embodiments, at least a portion of the heat exchanger 400 is configured to be disposed opposite to an air intake grille 510 of a vehicle.

[0122] The air intake grille 510 is typically located at the front of the vehicle. When the vehicle is in motion, outside air (or natural wind) enters the vehicle through the air intake grille 510. At least a portion of the heat exchanger 400 is positioned relative to the vehicle's air intake grille 510, allowing heat exchange between the outside air (or natural wind) and the heat exchanger 400. Simultaneously, the heat exchange assembly 1 with adjustable air outlet 102 opening of the present application can achieve thermal management of the entire vehicle at a relatively small air outlet 102 opening. This also reduces the vehicle's wind resistance.

[0123] The heat exchange component provided in the embodiment of the present application couples the natural air intake and the blower air intake. When the vehicle speed is high and the natural air cooling effect is good, the opening of the air outlet can be reduced to reduce the air volume blown by the fan onto the heat exchanger. When the vehicle speed is low and the natural air cooling effect is insufficient, the opening of the air outlet can be increased to increase the air volume blown by the fan onto the heat exchanger, thereby optimizing the wind resistance of the entire vehicle at different vehicle speeds.

[0124] Please combine Figure 2 as well as Figure 3In some embodiments, there are two air guides, and at least part of the heat exchanger 400 is disposed between the two air guides.

[0125] The two air guides can be arranged horizontally to the left and right, or vertically to the top and bottom.

[0126] In some examples, the two air guides may be arranged horizontally left and right, with at least a portion of the heat exchanger 400 disposed between the two air guides.

[0127] The number of the fans 300 may be one or more. In this application, the number of the fans 300 is not limited.

[0128] In some examples, two air guides can be arranged horizontally left and right, at least part of the heat exchanger 400 is set between the two air guides, and the number of fans 300 is one, that is, one fan 300 can blow air to the two air guides.

[0129] Furthermore, the fan 300 and the air guide can be connected via a connecting pipe 600. One end of the connecting pipe is connected to the air outlet of the fan 300, and the other end of the connecting pipe is connected to the air inlet of the air guide.

[0130] Please combine Figure 4 For example, the connecting pipe 600 can be provided with a first pipe opening 601, a second pipe opening 603 and a third pipe opening 605. The first pipe opening 601 of the connecting pipe 600 is connected to the blowing port of the fan 300, and the gas introduced by the fan 300 is sent to the two air guide parts through the second pipe opening 603 and the third pipe opening 605 respectively.

[0131] The second pipe opening 603 can be connected to an air guide, and the third pipe opening 605 can be connected to an air guide. When the fan 300 is in operation, the fan 300 draws in natural wind from the outside and air humidified by the humidifier, which then enter the two air guides through the connecting pipe 600. Since there is a gap between the first housing 100 of each air guide and the air guide cover 200, the cooling air is blown onto the heat exchanger 400 by the combined action of the special smooth curved surface of the first housing 100 and the air guide cover 200.

[0132] In some other examples, two fans may be provided, with one fan blowing air toward one air guide and the other fan blowing air toward the other air guide. This can increase the air volume directed toward the heat exchanger.

[0133] Please combine Figure 3In some embodiments, the air guide comprises a first housing 100 and an air guide cover 200. The first housing 100 is provided with an air inlet 101 and an air outlet 102; the air guide cover 200 is movable relative to the first housing 100 to cover or open the air outlet 102, so that the opening of the air outlet 102 is adjustable.

[0134] In these embodiments, the air guide cover 200 moves relative to the first housing 100 to change the opening size of the air outlet 102, thereby changing the air volume of the air outlet.

[0135] In some examples, when the air scoop 200 blocks all of the air outlets 102 , the opening of the air outlet 102 is the smallest. When the air scoop 200 does not block any of the air outlets 102 , the opening of the air outlet 102 is the largest.

[0136] In some examples, the maximum and minimum openings of the air outlet 102 can be set according to actual needs. A limiter can also be provided so that the maximum opening is achieved when the air guide cover 200 partially blocks the air outlet. A limiter can also be provided so that the minimum opening is achieved when the air guide cover 200 partially blocks the air outlet. This embodiment of the present application is not limited to this.

[0137] In some embodiments, the first housing 100 is rotatably connected to the air scoop 200. Rotating the air scoop 200 can adjust the opening of the air outlet 102. A driver 530 can be used to drive the air scoop 200 to rotate relative to the first housing 100. The driver 530 can be a servo motor.

[0138] Please combine Figure 3 、 Figure 5 as well as Figure 6 In some embodiments, the first housing 100 includes: a first cover plate 110 and a second cover plate 120 disposed opposite each other along a first direction, for mounting the air scoop 200; the first housing 100 also includes a middle housing 130, with opposite ends of the middle housing 130 connected to the first cover plate 110 and the second cover plate 120, respectively. The first cover plate 110 can be fixedly connected to the middle housing 130, for example, by welding. The second cover plate 120 can also be fixedly connected to the middle housing 130, for example, by welding.

[0139] Please combine Figure 2 and Figure 3 When there are two air guides and at least part of the heat exchanger 400 is disposed between the two air guides, the structures of the two air guides can be symmetrical with each other. One air guide has two cover plates: a first cover plate 110 and a second cover plate 120 disposed opposite each other along the first direction. The two air guides have four cover plates, and the four cover plates are symmetrical with each other.

[0140] Please combine Figure 5, and along the first direction, the opposite ends of the air scoop 200 are rotatably connected to the first cover plate 110 and the second cover plate 120 respectively. In this way, when the air scoop 200 rotates relative to the middle housing 130, the air scoop 200 can cooperate with the first housing 100, thereby changing the opening of the air outlet 102.

[0141] A first mounting hole 112 may be defined on the first cover plate 110, and a second mounting hole 113 may be defined on the second cover plate 120. A first rotating shaft 201 and a second rotating shaft 202 may be fixedly provided at opposite ends of the air scoop 200. The first rotating shaft 201 may be rotatably mounted in the first mounting hole 112, and the second rotating shaft 202 may be rotatably mounted in the second mounting hole 113. A driving member 530 may be connected to the first rotating shaft 201, thereby enabling the driving member 530 to drive the air scoop 200 to rotate relative to the first housing 100.

[0142] Please combine Figure 6 、 Figure 7 、 Figure 8 as well as Figure 9 In some embodiments, the central housing 130 includes a first sidewall 132, a second sidewall 133, and a third sidewall 134, which are sequentially bent and connected, and an air guide 136. The first sidewall 132 is located on the side of the third sidewall 134 facing away from the heat exchanger 400. The air guide 136 is connected to the end of the third sidewall 134 facing away from the second sidewall 133 and is curved. This facilitates adjusting the opening of the air outlet 102 when rotating the air guide cover 200.

[0143] Please combine Figure 3 as well as Figure 6 In some examples, the first sidewall 132 and the third sidewall 134 are arranged along the second direction.

[0144] Please combine Figure 9 In some embodiments, the air guide portion 136 includes a first end 137, a first extension portion 138 and a second end 139 connected in sequence, the first end 137 is connected to an end of the third side wall 134 away from the second side wall 133, at least a portion of the first extension portion 138 is located on a side of the first end 137 away from the first side wall 132, and at least a portion of the first extension portion 138 is located on a side of the second end 139 away from the first side wall 132.

[0145] The middle housing 130 is formed with a first cavity 131. Specifically, the first side wall 132, the second side wall 133, and the third side wall 134 form the first cavity 131. The first cavity 131 is communicated with the air inlet 101, and the first cavity 131 is communicated with the air outlet 102.

[0146] Please combine Figure 5 as well as Figure 10In some embodiments, the air guide cover 200 includes a first side 210 and a second side 220 relative to each other. Along the first direction, the opposite ends of the air guide cover 200 close to the first side 210 are rotatably connected to the first cover plate 110 and the second cover plate 120 close to the first side wall 132, respectively. The air guide portion 136 cooperates with the end of the air guide cover 200 close to the second side 220 so that the opening of the air outlet 102 can be adjusted.

[0147] Please combine Figure 5 In some examples, a first rotating shaft 201 and a second rotating shaft 202 may be fixedly provided at opposite ends of the air scoop 200 near the first side 210. The first rotating shaft 201 may be rotatably mounted on the first mounting hole 112, and the second rotating shaft 202 may be rotatably mounted on the second mounting hole 113. The driving member 530 may be connected to the first rotating shaft 201, so that the driving member 530 may be able to drive the air scoop 200 to rotate relative to the first shell 100. The coaxial arrangement of the first rotating shaft 201 and the second rotating shaft 202 together form the rotating axis of the air scoop. Under the action of the driving member 530, the air scoop 200 may rotate around the above-mentioned rotating axis, thereby controlling the opening of the air outlet 102 to change the amount of air blown from the air outlet 102 to the heat exchanger 400.

[0148] The air guide portion 136 is coupled to an end of the air guide cover 200 near the second side 220. The air guide portion 136 may be arc-shaped. In this way, the air guide cover 200 is adapted to cooperate with the air guide portion 136, so that the opening of the air outlet 102 can be changed according to the rotation angle of the air guide cover 200.

[0149] In some embodiments, the air scoop 200 can be curved to fit within the air guide portion 136. In some examples, the air scoop 200 is curved in a cross-section along the second direction, where the second direction is perpendicular to the first direction. The curved shape of the air scoop 200 in a cross-section along the second direction allows the air scoop 200 to fit well within the first housing 100, facilitating adjustment of the opening of the air outlet 102 formed by the air scoop 200 and the first housing 100 when the air scoop 200 is rotated.

[0150] Reference Figure 9 as well as Figure 10 Specifically, the air guide cover 200 also includes a second extension portion 230, which is located between the first side 210 and the second side 220. The first side 210 is arranged close to the first side wall 132, and at least a portion of the second extension portion 230 is located on the side of the first side 210 away from the second side wall 133, and at least a portion of the second extension portion 230 is located on the side of the second side 220 away from the second side wall 133.

[0151] Reference Figure 9 as well as Figure 10In some embodiments, the end of the air guide cover 200 close to the first side 210 can be attached to the end of the first side wall 132 away from the second side wall 133. This can ensure that the wind blown by the fan is blown more toward the heat exchanger through the air outlet 102.

[0152] In some embodiments, a convex portion 135 is provided at one end of the air guide portion 136 away from the first side wall 132. Figure 12 and reference Figure 13 , Figure 12 as well as Figure 13 The diagram shows a structure when the air volume from the air outlet 102 blowing toward the heat exchanger is minimum, that is, when the opening angle of the air guide cover is minimum. When the air volume from the air outlet 102 blowing toward the heat exchanger 400 is minimum, the air guide cover 200 is attached to the side of the protrusion 135 away from the first side wall 132, so that part of the air guide cover 200 is separated from the air guide portion 136.

[0153] The protrusion 135 prevents the air scoop 200 from completely fitting with the air guide portion 136 when the air outlet 102 is at its minimum opening, that is, when the air volume from the air outlet 102 to the heat exchanger is at its minimum. Otherwise, if the air scoop 200 completely fits with the air guide portion 136, the exhaust of air from the first housing 100 will be affected.

[0154] To facilitate placement of the end of the second side 220 against the side of the protrusion 135 facing away from the first sidewall 132, the side of the end of the second side 220 facing the protrusion 135 can be shaped to match the side of the protrusion 135 facing away from the first sidewall 132. In some examples, the side of the end of the second side 220 facing the protrusion 135 is a linear structure, and the side of the protrusion 135 facing away from the first sidewall 132 is also a linear structure.

[0155] Please combine Figure 11 In some embodiments, a stopper 111 is provided on the side of the first cover 110 facing the middle shell 130. The stopper 111 is provided on the side of the air scoop 200 facing away from the second side wall 133, so that when the air scoop 200 abuts against the stopper 111, the air volume blown from the air outlet 102 to the heat exchanger is maximized. Figure 8 and reference Figure 9 , Figure 8 as well as Figure 9 The diagram shows the structure when the air volume from the air outlet 102 to the heat exchanger is the largest, that is, when the opening angle of the air guide cover is the largest.

[0156] When the air outlet 102 is at its maximum opening, the air volume blown toward the heat exchanger from the air outlet 102 is at its maximum, and the air guide cover 200 abuts against the stopper 111. The stopper 111 limits the maximum opening angle of the air guide cover 200 (i.e., the maximum opening of the air outlet 102).

[0157] In some embodiments, the fan can be a blower. The heat exchange component in the present application can be a cooling system with a controllable air duct to supply air. In the related art, a cooling fan is usually arranged behind the heat exchanger. However, since the traditional cooling fan has a wind shield, the wind resistance is large due to the effect of the wind shield. Especially when the vehicle is running at high speed, the wind shield will block the natural wind from passing through the heat exchanger, reducing the efficiency of the heat exchanger. In addition, when the fan is working, the wind speed of the traditional cooling fan is only high in the projected area of the fan on the heat exchanger. The wind speed of the remaining areas is low due to the effect of the fan wind shield, and the heat dissipation efficiency is low. In addition, the inlet temperature of the traditional cooling fan is the same as the natural wind temperature. In the present application, there is no traditional cooling fan, but a blower is provided, and the opening of the air outlet 102 of the air guide is adjustable to change the amount of air blown to the heat exchanger from the air outlet 102. This can reduce the wind resistance of the entire vehicle, and when the vehicle speed is high, natural wind can pass through the heat exchanger fully.

[0158] In some embodiments, the air may be pressurized and then flow out through the air outlet 102 , which results in a high wind speed and slight expansion, thereby reducing the inlet air temperature.

[0159] In some embodiments, the blower of the present application can also be connected in series with the air-conditioning box blower to increase the blowing effect. Specifically, an air duct can be led out from the rear side of the air-conditioning blower to the air inlet of the above-mentioned blower.

[0160] In some embodiments, the blower of the air conditioner box can be used to replace the above-mentioned fan of the present application, which can reduce costs. An air duct can be led out from the rear side of the blower of the air conditioner to the connecting pipe 600 of the fan.

[0161] Please combine Figure 14 In some embodiments, the heat exchanger 400 can be mainly divided into five areas, namely the left fan air inlet area 701, the left air inlet junction area 703, the natural air inlet area 705, the right air inlet junction area 707, and the right fan air inlet area 709.

[0162] Please combine Figure 14 The natural air intake area 705 may refer to an area where external air (natural wind) is blown from the vehicle's air intake grille 510 to the heat exchanger 400 .

[0163] The left fan air inlet area 701 may refer to the area where the air blown out of the air outlet of the fan on the left side is blown toward the heat exchanger from the air outlet 102 through the air guide of the air guide member. Figure 9 , Figure 9 The diagram roughly illustrates the relationship between the opening angle of the left air guide cover and the left fan air inlet area 701. L1 is the distance between the intersection point 1 of the extension line of one end of the second side 220 of the air guide cover 200 and the plane where the heat exchanger is located, and the intersection point 2 of the first shell 100 and the plane where the heat exchanger is located.

[0164] Figure 9 The area of the heat exchanger partially covered by L1 can be the left fan inlet area 701, and the area of the left fan inlet area can be the area of L1 and the width of the air guide plate (such as Figure 14 The method for representing the right fan inlet area 709 and the method for calculating the area of the right fan inlet area 709 can refer to the method for representing the left fan inlet area 701 and the method for calculating the area of the left fan inlet area 701, and will not be repeated here.

[0165] The left fan inlet area 701 and the natural air inlet area 705 partially intersect on the heat exchanger 400. This intersecting area is referred to as the left inlet boundary area 703. The representation of the right inlet boundary area 707 can be referred to as the representation of the left inlet boundary area 703 and will not be repeated here.

[0166] It is easy to understand that the areas of the five areas of the heat exchanger 400 are variable. The natural air inlet area 705 is related to the vehicle speed. When the vehicle speed is high, the natural air inlet area 705 will increase. The fan air inlet area (the left fan air inlet area and the right fan air inlet area) will change with the angle of the air guide cover 200 (or the opening of the air outlet 102). If the opening of the air outlet 102 is reduced, the amount of air blown to the heat exchanger by the air outlet 102 is reduced, which may cause the area of the fan air inlet area (the left fan air inlet area, the right fan air inlet area) to become smaller. If the opening of the air outlet 102 becomes larger, the amount of air blown to the heat exchanger by the air outlet 102 becomes larger, which may cause the area of the fan air inlet area (the left fan air inlet area, the right fan air inlet area) to become larger. The area of the intersection zone (left air inlet intersection zone, right air inlet intersection zone) is mainly based on the natural coupling of vehicle speed, wind guide cover angle (or the opening of air outlet 102) and wind speed of fan 300. Due to the viscosity of air, the high-speed cooling wind coming out of the gap between the first shell 100 and the wind guide cover 200 can also drive the edge layer air to flow faster, thereby enhancing the cooling effect.

[0167] The heat exchange component provided in the embodiment of the present application couples the natural air intake and the blower air intake. When the vehicle speed is high and the natural air cooling effect is good, the opening of the air outlet can be reduced to reduce the air volume blown by the fan onto the heat exchanger. When the vehicle speed is low and the natural air cooling effect is insufficient, the opening of the air outlet can be increased to increase the air volume blown by the fan onto the heat exchanger, thereby optimizing the wind resistance of the entire vehicle at different vehicle speeds.

[0168] The heat exchanger 400 may include an air conditioning heat exchanger 410 and a cooling heat exchanger 420. The air conditioning heat exchanger is positioned opposite the vehicle's air intake grille 510, while the cooling heat exchanger is located on the side of the air conditioning heat exchanger facing away from the air intake grille 510. The air conditioning heat exchanger 410 may be used to exchange heat for the air conditioner, while the cooling heat exchanger 420 may be used to exchange heat for the engine.

[0169] In a second aspect, the present application also provides a vehicle, which includes an air intake grille 510 and the above-mentioned heat exchange assembly 1. The vehicle includes the above-mentioned heat exchange assembly and has all the beneficial effects of the above-mentioned heat exchange assembly, which will not be repeated in this disclosure.

[0170] The air intake grille 510 is typically located at the front of the vehicle. When the vehicle is in motion, outside air (natural wind) enters the vehicle through the air intake grille 510. At least a portion of the heat exchanger 400 is positioned opposite the vehicle's air intake grille 510, allowing the natural wind to exchange heat with the heat exchanger 400. Simultaneously, the heat exchange assembly 1 with adjustable air outlet 102 opening of the present application can achieve thermal management of the entire vehicle at a relatively small air outlet 102 opening, thereby reducing the vehicle's wind resistance.

[0171] In some examples, the specific location of the heat exchange assembly can be designed based on the overall vehicle layout. The heat exchange assembly can be placed on the top, bottom, left, or right side. Positioning it on the top or bottom side can optimize the front bumper shielding area to prevent air inflow.

[0172] In some examples, the driving member 530 may also be removed to achieve the ultimate cost reduction.

[0173] The vehicle may be a fuel vehicle, a plug-in hybrid vehicle, a new energy vehicle, etc., and this disclosure does not make any specific limitations on this.

[0174] Please combine Figure 2 as well as Figure 15 In some embodiments, the vehicle further includes a humidifier 520 , which is connected to one end of the fan 300 where the air inlet 301 is located.

[0175] In some embodiments, the vehicle further includes an air conditioner, and the humidifier 520 is used to collect condensed water discharged from the air conditioner.

[0176] In some examples, the humidifier 520 may be located below the air conditioner to collect condensed water discharged from the air conditioner.

[0177] Please combine Figure 15 、 Figure 16 as well as Figure 17 In some embodiments, the humidifier 520 includes a humidifier cover 521 and a humidifier body 522. The humidifier body 522 is provided with a accommodating cavity 527. The humidifier cover 521 is covered on the humidifier body 522. The humidifier cover 521 is provided with a first through hole 524 connected to the accommodating cavity 527. The first through hole 524 is used to collect condensed water discharged from the drain outlet of the air conditioner into the accommodating cavity 527.

[0178] Please combine Figure 15 、 Figure 16 as well as Figure 17 In some embodiments, the humidifier 520 may also be provided with a water supply pipe 528, which is spaced apart from the first through hole 524. When the humidifier cover 521 is assembled to the humidifier body 522, the water supply pipe 528 passes through the through hole of the humidifier cover 521, exposing part of the water supply port of the water supply pipe 528 to the outside. When the condensed water discharged from the drain outlet of the air conditioner is insufficient, cooling water can be added to the accommodating cavity 527 through the water supply pipe 528 to humidify the air.

[0179] In some embodiments, first through hole 524 is located below the air conditioner's drain outlet. First through hole 524 is located above humidifier 520 and is used to collect condensed water discharged from the air conditioner's drain outlet. To facilitate the drainage of condensed water from the air conditioner, the entire humidifier 520 is arranged below the drain outlet of the air conditioner housing.

[0180] Please combine Figure 15 、 Figure 16 as well as Figure 17 In some embodiments, the humidifier body 522 is provided with a second through hole 525 communicating with the accommodating cavity 527. The second through hole 525 is spaced apart from the bottom of the humidifier body 522.

[0181] When there is too much condensed water from the air conditioner, it can be discharged outside the vehicle through the second through hole 525. When the fan 300 is working, the moist air humidified by the humidifier 520 enters the fan 300 through the discharge hole 526. At this time, the accommodating chamber 527 will generate negative pressure, and the discharge hole 526 can eliminate the negative pressure to ensure that there is enough moisture to enter the blower through the discharge hole 526.

[0182] This application provides a vehicle capable of recycling and cooling air conditioning condensate. In related art, air conditioning condensate is typically discharged directly. However, since air conditioning condensate is generally at a low temperature and serves as a high-quality cooling source, it can be recycled and atomized and blown onto a heat exchanger, significantly cooling the heat exchanger. In this application, a humidifier 520 is used to collect condensate discharged from the air conditioner. Furthermore, if the amount of condensate is insufficient, ordinary domestic water can be added to the humidifier, providing a variety of cooling water sources.

[0183] Furthermore, when the air in the passenger compartment is cooled and the external circulation mode is turned on, the cold air in the passenger compartment can be recycled for cooling the heat exchanger.

[0184] In some embodiments, the angle of the air scoop 200 may be designed to be a fixed value.

[0185] Thirdly, the present application also provides a control method for a heat exchange assembly. The heat exchange assembly includes a fan, an air guide, and a heat exchanger 400. The fan has an air outlet; the air guide is provided with an air inlet 101 and an air outlet 102, which are connected to each other. The air inlet 101 is used to take in air and is connected to the air outlet of the fan. The fan 300 can draw in natural wind from the outside and then blow it into the air guide through the air inlet 101. Since the air guide is provided with an air outlet 102, the wind will be blown onto the heat exchanger 400 through the air outlet 102.

[0186] Specifically, the air blown out of the air outlet of the fan will enter the air guide from the air inlet 101, and will be blown toward the heat exchanger from the air outlet 102 through the air guide of the air guide; wherein, the opening of the air outlet 102 is adjustable.

[0187] Please combine Figure 20 , wherein the control method of the heat exchange component provided in this application includes:

[0188] The opening of the air outlet 102 is adjusted to change the air volume blown from the air outlet 102 to the heat exchanger 400 .

[0189] In the related art, the air scoop of the vehicle can only be opened at a fixed angle to discharge air through the heat exchanger. Even when the vehicle is running at a high altitude, the opening angle of the air scoop of the vehicle cannot be adjusted.

[0190] However, due to different driving conditions of the vehicle, in some scenarios the air volume output at this fixed angle is already greater than the air volume required for cooling and heat exchange. Since the larger the opening angle of the air guide hood, the greater the wind resistance, in this case, there will be greater wind resistance, which is not conducive to the endurance of the entire vehicle.

[0191] In the embodiment of the present application, the opening of the air outlet 102 is adjusted to change the air volume blown from the air outlet 102 toward the heat exchanger 400. In other words, the air volume blown onto the heat exchanger is adjustable rather than being fixed. Thus, when a smaller air volume is required, the opening of the air outlet 102 can be adjusted to be smaller, thereby changing the air volume blown from the air outlet 102 toward the heat exchanger 400. This reduces the air volume blown from the air outlet 102 toward the heat exchanger 400, reduces the opening angle of the air guide, and also reduces wind resistance.

[0192] Please combine Figure 21 In some embodiments, adjusting the opening of the air outlet to change the air volume blown from the air outlet 102 to the heat exchanger includes:

[0193] Get the vehicle's parameters;

[0194] The opening of the air outlet is adjusted according to the parameters of the vehicle to change the air volume blown from the air outlet 102 to the heat exchanger.

[0195] In some embodiments, obtaining vehicle parameters includes:

[0196] Get the vehicle speed and the refrigerant temperature at the air conditioner heat exchanger inlet;

[0197] The adjusting the opening of the air outlet according to the parameters of the vehicle to change the air volume blown from the air outlet 102 to the heat exchanger includes:

[0198] determining a first opening degree of the air outlet according to the vehicle speed and the refrigerant temperature;

[0199] The opening of the air outlet is adjusted to a first opening to change the air volume blown from the air outlet to the heat exchanger.

[0200] In some embodiments, obtaining vehicle parameters includes:

[0201] Get vehicle speed and engine water temperature;

[0202] The adjusting the opening of the air outlet according to the parameters of the vehicle to change the air volume blown from the air outlet 102 to the heat exchanger includes:

[0203] determining a second opening of the air outlet according to the vehicle speed and the engine water temperature;

[0204] The opening of the air outlet is adjusted to a second opening to change the air volume blown from the air outlet to the heat exchanger.

[0205] In some embodiments, obtaining vehicle parameters includes:

[0206] Obtain vehicle speed, refrigerant temperature at the air conditioning heat exchanger inlet, and engine water temperature;

[0207] The adjusting the opening of the air outlet according to the parameters of the vehicle to change the air volume blown from the air outlet to the heat exchanger includes:

[0208] determining a first opening degree of the air outlet according to the vehicle speed and the refrigerant temperature at the inlet of the air conditioner heat exchanger;

[0209] determining a second opening of the air outlet according to the vehicle speed and the engine water temperature;

[0210] If the value of the first opening is the same as the value of the second opening, the opening of the air outlet is adjusted to the first opening to change the air volume blown from the air outlet 102 to the heat exchanger;

[0211] If the first opening value is different from the second opening value, the opening of the air outlet is adjusted to the larger one of the first opening value and the second opening value to change the air volume blown from the air outlet 102 to the heat exchanger.

[0212] In these embodiments, the opening degree of the air outlet 102 is determined by three parameters: vehicle speed, refrigerant temperature at the inlet of the air conditioner heat exchanger, and engine water temperature.

[0213] If the value of the first opening is different from the value of the second opening, the opening of the air outlet is adjusted to the larger of the first opening and the second opening to change the amount of air blown toward the heat exchanger by the air outlet 102, so that the air outlet 102 can blow enough air toward the heat exchanger for heat exchange.

[0214] Among them, there is a corresponding relationship between the vehicle's air outlet parameters and the opening of the air outlet. The corresponding relationship between the air outlet parameters and the opening of the air outlet may be different for different vehicle models. The corresponding relationship between the air outlet parameters and the opening of the air outlet of a certain vehicle model can be obtained through actual testing of a certain vehicle model, and can be summarized in a table. In this way, during the actual use of the vehicle later, the control system can obtain the vehicle's air outlet parameters and adjust the opening of the air outlet according to the air outlet parameters.

[0215] In some embodiments, the opening angle of the air guide cover 200 can be represented by referring to Figure 10 , Figure 10 The P in the figure is the opening angle of the air guide cover 200. Figure 10In the figure, the method of expressing the opening angle of the air scoop 200 is as follows: determine the first point, the second point and the third point, the first point is the endpoint of the second side 220 of the air scoop, the second point is the intersection of the first side 210 of the air scoop and the first side wall 132, and it is easy to understand that the first side 210 rotates around the second point. The third point is the endpoint of the side of the convex portion 135 away from the air scoop 200, and it is easy to understand that when the opening of the air outlet is the smallest, the contact point between the end of the second side of the air scoop 200 and the convex portion 135 is the third point. The first point and the second point can form a first straight line, and the second point and the third point can form a second straight line. The angle between the first straight line and the second straight line is Figure 10 The opening angle of the air guide cover 200 is Figure 10 In the embodiment, the opening angle of the air guide cover 200 is 60 degrees.

[0216] At the same time, it can be seen that Figure 10 The air guide cover 200 is held against the limit block 111, that is, Figure 10 In the middle, the opening angle of the air guide cover 200 reaches the maximum, and the air volume blown to the heat exchanger from the air outlet 102 is the largest. By setting the limit block 111, the maximum opening angle of the air guide cover 200 (that is, the maximum opening of the air outlet 102) can be limited. Figure 10 ) and the minimum angle ( Figure 12 The example in the figure shows movement between 0 degrees).

[0217] Please combine Figure 12 , Figure 12 is a structural diagram of the air guide cover 200 when the opening angle is the smallest. Figure 12 Since the first point and the third point are in contact and coincide with each other, that is, the first straight line formed by the first point and the second point (please refer to Figure 12 The second straight line formed by the second and third points (see Figure 12 The first straight line and the second straight line coincide with each other (the dotted line in the figure). At this time, the angle between the first straight line and the second straight line is 0 degrees. Figure 12 In the embodiment, the opening angle of the air scoop 200 is 0 degrees. However, due to the presence of the protrusion 135, there is a gap between the air scoop 200 and the air guide portion 136. By providing the protrusion 135, when the opening of the air outlet 102 is configured to the minimum opening, the air scoop 200 can be partially separated from the air guide portion 136. This prevents the air scoop 200 from completely fitting with the air guide portion 136 when the opening of the air outlet 102 is configured to the minimum opening, that is, when the air volume blown to the heat exchanger by the air outlet 102 is at a minimum. Otherwise, if the air scoop 200 and the air guide portion 136 are completely fitted together, it will affect the discharge of air in the first housing 100.

[0218] For example, in some examples, combine Figure 18 as well as Figure 19 The table in the figure is obtained based on actual measurements of a certain vehicle model. The opening angle of the air scoop 200 indicates the opening of the air outlet 102. Generally, within the adjustment range, the larger the opening angle of the air scoop 200, the larger the opening of the air outlet 102. According to the above control method, Figure 18 as well as Figure 19 In the corresponding vehicle model, when the vehicle speed is 100 km / h, the refrigerant temperature at the inlet of the air-conditioning heat exchanger is 80 degrees Celsius, and the engine water temperature is 110 degrees Celsius, the corresponding air guide hood 200 opening angle is 0 degrees.

[0219] When the vehicle speed is 100 km / h and the engine water temperature is 110 degrees Celsius, the corresponding opening angle of the air scoop 200 is 10 degrees. The controller then controls the air scoop 200 to rotate relative to the first housing 100, adjusting the opening angle of the air scoop 200 to 10 degrees. This adjusts the opening of the air outlet, thereby changing the air volume blown from the air outlet 102 to the heat exchanger, ensuring that the heat exchanger 400 receives sufficient air volume for heat exchange.

[0220] Combined with the table in the figure, in this vehicle model, when the opening angle of the air scoop 200 ranges from 40 degrees to 60 degrees, for example, when the opening angle of the air scoop 200 is 40 degrees, 50 degrees, or 60 degrees, this is the cooling area dominated by the fan. As the vehicle speed increases, the opening angle of the air scoop can be controlled to be reduced to reduce wind resistance (that is, the opening angle of the air outlet 102 can be reduced). In some examples, at this time, due to the large opening angle of the air scoop 200, the air volume discharged from the air outlet 102 is large, and the air volume discharged from the air outlet 102 can be greater than the air volume of natural wind.

[0221] When the opening angle of the air guide cover 200 is within 30 degrees, the fan cooling and natural wind cooling are in a balanced range. In some examples, the air volume of the air outlet 102 is equal to the air volume of the natural wind.

[0222] When the opening angle of the air scoop 200 is between 10 and 20 degrees, for example, when the opening angle of the air scoop 200 is 10 or 20 degrees, natural wind is the primary cooling method, and the fan assists in cooling the area. As the vehicle speed increases, the opening angle of the air scoop can be reduced (that is, the opening of the air outlet 102 can be reduced) to reduce wind resistance. In some examples, the air volume discharged from the air outlet 102 can be less than the air volume of natural wind.

[0223] When the air scoop 200 is open at 0 degrees, it may be because the refrigerant temperature is not high and the natural airflow is sufficient for cooling as the vehicle speed increases, so there is no need to open the air scoop. Alternatively, the natural airflow completely dominates the cooling area, so there is no need to open the air scoop. In some examples, the air volume discharged from the air outlet 102 can be less than the natural air volume.

[0224] It should be noted that the parameters in the table in the figure are all examples. The specific values can be confirmed by simulation or calibration based on the characteristics of the specific vehicle model.

[0225] In some embodiments, the steps after adjusting the opening of the air outlet to change the air volume blown from the air outlet 102 to the heat exchanger include:

[0226] Determining whether the opening of the air outlet is less than or equal to a first threshold;

[0227] If the opening of the air outlet is less than or equal to a first threshold, controlling the fan to be turned off;

[0228] If the opening of the air outlet is greater than a first threshold, the fan is controlled to turn on.

[0229] In some examples, the first threshold value may be a minimum opening, that is, the opening angle of the air guide cover 200 is 0 degrees. In these examples, the steps after adjusting the opening of the air outlet to change the air volume blown from the air outlet 102 to the heat exchanger include:

[0230] Determine whether the opening angle of the air guide cover 200 is 0 degrees;

[0231] If the opening angle of the air guide cover 200 is 0 degrees, the fan is controlled to be turned off;

[0232] If the opening angle of the air guide cover 200 is greater than 0 degrees, the fan is controlled to be turned on.

[0233] A convex portion 135 may be provided on one side of the first shell of the air guide. When the air volume from the air outlet 102 to the heat exchanger is at a minimum, the air guide cover 200 of the air guide is attached to the side of the convex portion 135 facing away from the first shell, so that part of the first shell is spaced apart from the air guide cover 200.

[0234] The protrusion 135 prevents the air scoop 200 from completely fitting with the air guide portion 136 when the air outlet 102 is at its minimum opening, that is, when the air volume from the air outlet 102 to the heat exchanger is at its minimum. Otherwise, if the air scoop 200 completely fits with the air guide portion 136, the exhaust of air from the first housing 100 will be affected.

[0235] In some embodiments, the vehicle includes a humidifier 520;

[0236] If the opening of the air outlet is greater than the first threshold, the steps after controlling the fan to turn on include:

[0237] If there is water in the accommodating chamber of the humidifier 520, the humidifier is controlled to be turned on;

[0238] If there is no water in the accommodating chamber of the humidifier 520 , the humidifier is controlled to be closed.

[0239] After the fan is turned on, it is determined whether there is water in the accommodating chamber of the humidifier 520. If there is water in the accommodating chamber of the humidifier 520, the humidifier is controlled to be turned on; if there is no water in the accommodating chamber of the humidifier 520, the humidifier is controlled to be turned off, thereby effectively preventing the humidifier from being damaged.

[0240] In some embodiments, the vehicle includes a humidifier 520; if the opening of the air outlet is less than or equal to the first threshold, the steps after controlling the fan to be turned off include:

[0241] The humidifier is controlled to be closed.

[0242] After controlling the fan to shut down, the humidifier is also controlled to shut down, which saves energy and protects the environment.

[0243] The control method of the heat exchange component provided in the present application can adjust the angle of the air guide cover according to the vehicle speed, thereby balancing the air intake ratio of natural wind and blown air, and improving the air intake efficiency.

[0244] When the vehicle needs to dissipate heat, the opening angle of the air scoop 200 can be determined based on parameters such as vehicle speed (the larger the opening angle is). In some embodiments, when the opening angle of the air scoop 200 is 0 degrees, the fan is turned off. When the opening angle of the air scoop 200 is not 0 degrees, the fan is turned on.

[0245] In some embodiments, the opening degree of the air outlet depends on the opening angle of the air scoop, that is, within a certain range, the larger the opening angle of the air scoop, the larger the opening degree of the air outlet. The smaller the opening angle of the air scoop, the smaller the opening degree of the air outlet.

[0246] In some embodiments, the opening degree of the air outlet depends on the opening angle of the air scoop, that is, within a certain range, the larger the opening angle of the air scoop, the larger the opening degree of the air outlet. The smaller the opening angle of the air scoop, the smaller the opening degree of the air outlet.

[0247] That is, the first opening angle of the air guide cover can be obtained according to the first air outlet parameter and the second air outlet parameter, and the second opening angle of the air outlet can be obtained according to the first air outlet parameter and the third air outlet parameter.

[0248] Then, the first opening angle and the second opening angle of the air guide cover are compared. If the value of the first opening angle is greater than the value of the second opening angle, the air guide cover is controlled to the first opening angle; and if the value of the second opening is greater than the value of the first opening, the air outlet is controlled to the second opening.
