[0043] Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0044] As Figures 1 to 6 shown, according to the first aspect of the embodiments of the present disclosure, a heat dissipation device 100 applied to a vehicle is provided, including: a flow guiding member 110 for being disposed on the vehicle body 200 of the vehicle, the flow guiding member 110 is formed with an air inlet 101, an air outlet 102 and an air passage 103, the air passage 103 communicates between the air inlet 101 and the air outlet 102, the air inlet 101 is used to be arranged behind the wheel 400 of the vehicle to access the airflow around the wheel 400 when the wheel 400 rotates, and the air outlet 102 is used to be arranged corresponding to the battery pack 300 of the vehicle; a filter member 120 disposed at the air inlet 101 for filtering the airflow.

[0045] The heat dissipation device 100 applied to a vehicle provided by an embodiment of the present disclosure includes a flow guiding member 110 and a filtering member 120. Among them, the flow guiding member 110 is formed with the aforementioned air inlet 101, air outlet 102, and air passage 103, and the filtering member 120 is arranged at the aforementioned air inlet 101; in practical applications, the air inlet 101 can be arranged corresponding to the wheel 400 of the vehicle. During the driving of the vehicle, the wheel 400 is in a rotating state and can drive the nearby gas to flow. Thus, based on the aforementioned setting, the air inlet 101 can be used to access the air flow near the wheel 400. Correspondingly, the flow passage can guide the flow direction of the air flow so that the air flow flows toward the aforementioned air outlet 102; the air outlet 102 can be arranged corresponding to the battery pack 300 of the vehicle. Thus, after the air flow flows out of the flow guiding member 110 through the air outlet 102, it can further flow toward the battery pack 300. Based on the aforementioned setting, the heat dissipation device 100 applied to a vehicle can, during the driving of the vehicle, introduce the air flow near the wheel 400 into the air passage 103 through the air inlet 101 of the flow guiding member 110, and discharge the air flow toward the battery pack 300 through the air outlet 102 of the flow guiding member 110. When the battery pack 300 comes into contact with the air flow, heat exchange can occur. Thus, the aforementioned heat dissipation device 100 can continuously deliver the air flow to the battery pack 300 during the driving of the vehicle, thereby being able to improve the heat dissipation rate of the battery pack 300, reduce the temperature of the battery pack 300, and moreover, the aforementioned heat dissipation device 100 does not require the battery pack 300 to provide the energy required for air supply, can improve the heat dissipation effect on the battery pack 300 while avoiding increasing the energy consumption of the battery pack 300, and provides a guarantee for the cruising range of the vehicle; the filtering member 120 of the aforementioned heat dissipation device 100 can filter the air flow flowing through the air inlet 101 to intercept the dirt mixed in the air flow, reduce the risk of the dirt being discharged toward the battery pack 300 through the air outlet 102, is beneficial to avoiding the contamination of the battery pack 300, and can improve the safety and reliability of the aforementioned heat dissipation device 100.

[0046] It can be understood that, based on the aforementioned setting, the heat dissipation assembly can also guide and comb the air flow near the wheel 400 during the driving of the vehicle, thereby reducing the wind resistance of the wheel 400, which is beneficial to further reducing the energy consumption of the vehicle.

[0047] It should be noted that the aforementioned vehicle can be, but is not limited to, a new energy vehicle or a hybrid vehicle, etc. The aforementioned vehicle can include a vehicle body 200, wheels 400, and a battery pack 300. The aforementioned wheels 400 and the aforementioned battery pack 300 are both arranged on the vehicle body 200, the wheels 400 can rotate relative to the vehicle body 200, and the aforementioned battery pack 300 can be, but is not limited to, a storage battery or a fuel cell, etc. In practical applications, the heat dissipation device 100 applied to a vehicle provided by an embodiment of the present disclosure can be arranged on the aforementioned vehicle or used as a component of the aforementioned vehicle.

[0048] Exemplarily, such asFigures 4 to 6 As shown, in practical applications, the heat dissipation device 100 applied to a vehicle can be connected to the aforementioned vehicle body 200 and battery pack 300, so as to facilitate the installation and fixation of the heat dissipation device 100 and improve the stability and reliability of the heat dissipation device 100. Specifically, one end of the flow guide member 110 where the air inlet 101 is formed can be arranged on the wheel housing 210 of the vehicle body 200. For example, the flow guide member 110 can penetrate through the wheel housing 210, and one end of the flow guide member 110 where the air outlet 102 is formed can be arranged on the battery pack 300; the air inlet 101 can be flush with the wheel housing 210 or located between the wheel housing 210 and the wheel 400, and the air inlet 101 faces the circumferential side of the wheel 400, so that the air inlet 101 is arranged corresponding to the aforementioned wheel 400 and is convenient for accessing the airflow near the wheel 400 when the wheel 400 rotates. Among them, when the air inlet 101 is flush with the wheel housing 210, a relatively large spacing distance can be formed between the heat dissipation device 100 and the wheel 400, avoiding interference between the wheel 400 and the heat dissipation device 100 and being beneficial to improving the concealment of the heat dissipation device 100 and providing guarantee for the aesthetics of the vehicle; the air outlet 102 can be arranged close to the battery pack 300, and the conduction direction of the air outlet 102 can intersect or be parallel to at least one side wall of the battery pack 300, so that the air outlet 102 is arranged corresponding to the aforementioned battery pack 300 and is convenient for the airflow output from the air outlet 102 to contact the battery pack 300 to dissipate heat from the battery pack 300. Among them, when the conduction direction of the air outlet 102 is parallel to at least one side wall of the battery pack 300, it is convenient for the airflow output from the air outlet 102 to flow in a direction parallel to this side wall, thereby reducing the change in the flow direction of the airflow and the loss of kinetic energy, being beneficial to ensuring the airflow velocity on the surface of the battery pack 300 and improving the heat dissipation efficiency of the battery pack 300.

[0049] It can be understood that the battery pack 300 is generally in the shape of a roughly rectangular parallelepiped. Accordingly, the outer surface of the battery pack 300 may include a front end wall 301 and a rear end wall that are separated from each other in the length direction, a left side wall 302 and a right side wall that are separated from each other in the width direction, and an upper side wall 303 and a lower side wall that are separated from each other in the height direction. In actual applications, the length direction, width direction and height direction of the battery pack 300 match the length direction, width direction and height direction of the vehicle body 200, respectively. The upper side wall 303 is arranged toward the roof, the front end wall 301 is arranged toward the front of the vehicle, the left side wall 302 is arranged close to the main driver's door, and the width of the battery pack 300 is generally greater than the battery pack 300. The height of the battery pack 300 is smaller than the length of the battery pack 300, so that the area of ​​each side wall of the battery pack 300 is usually larger than the aforementioned front wall 301 and the rear wall; the conduction direction of the aforementioned air outlet 102 can intersect or be parallel to at least one side wall of the battery pack 300, that is, the conduction direction of the air outlet 102 can intersect or be parallel to at least one of the aforementioned upper side wall 303, the lower side wall, the left side wall 302 and the right side wall. Based on this, it is convenient for the airflow to contact with at least one of the aforementioned side walls and flow along the corresponding side wall after flowing out of the air outlet 102, which is beneficial to increase the contact area between the airflow and the battery pack 300, and further enhance the heat dissipation effect of the heat dissipation component on the battery pack 300.

[0050] For example, Figure 5 As shown, in actual application, the guide member 110 can be arranged behind the wheel 400, and the air inlet 101 can be arranged toward the peripheral side of the wheel 400, so that the air inlet 101 can be connected to the airflow around the wheel 400 when the vehicle is driving, and it is beneficial to the airflow output by the air outlet 102. It can be understood that the rear of the wheel 400 refers to the area between the wheel 400 and the rear of the vehicle. Specifically, considering that the battery pack 300 is usually located between the front wheel and the rear wheel of the vehicle, the air inlet 101 can be arranged behind the front wheel of the vehicle, the air outlet 102 can be arranged close to the front end wall 301 of the battery pack 300, and the conduction direction of the air outlet 102 can be consistent with the length direction of the battery pack 300, so as to facilitate the arrangement of the air inlet 101 and the air outlet 102 in the direction from the front to the rear of the vehicle, which is beneficial for the air flow direction in the air passage 103 and the air flow direction output by the air outlet 102 to conform to the gas pressure gradient in the external environment during the driving of the vehicle, thereby increasing the gas flow rate in the air passage 103 and the air flow rate output by the air outlet 102, thereby enhancing the heat dissipation effect of the heat dissipation component on the battery pack 300, and is beneficial for shortening the distance between the heat dissipation component and the battery pack 300, reducing the length requirement of the air passage 103, improving the structural compactness of the aforementioned heat dissipation device 100, reducing the overall volume of the aforementioned heat dissipation device 100 and the requirement for installation space, which is beneficial for realizing the concealed installation of the aforementioned heat dissipation device 100.

[0051] In some examples, along the direction from the air inlet 101 to the air outlet 102, the conduction area of the air passage 103 decreases.

[0052] In this technical solution, the conduction area of the air passage 103 can be set to decrease along the direction from the air inlet 101 to the air outlet 102; based on the foregoing setting, when the air passage 103 guides the air flow towards the air outlet 102, the distribution of the air flow can be made more concentrated, so that the air flow accelerates in the air passage 103, which is beneficial to increasing the air flow velocity output from the air outlet 102, and further improving the heat dissipation efficiency of the battery pack 300.

[0053] It can be understood that the conduction area of the air outlet 102 is smaller than that of the air inlet 101.

[0054] Such as Figures 1 to 4 As shown, in some examples, the flow guide member 110 includes: a cylindrical body portion 111, an installation wall and an air inlet 101 are respectively formed at both ends of the cylindrical body portion 111, the air passage 103 is formed inside the cylindrical body portion 111, and the installation wall is used to be arranged at one end of the battery pack 300; a rib portion 112, arranged on the circumferential side of the cylindrical body portion 111, the rib portion 112 forms an air outlet passage and an air outlet 102, and the air outlet passage communicates between the air passage 103 and the air outlet 102.

[0055] In this technical solution, the flow guide member 110 can include the foregoing cylindrical body portion 111 and the foregoing rib portion 112; based on the foregoing setting, on the one hand, it is convenient to structurally connect the flow guide member 110 to the battery panel, thereby improving the installation stability and reliability of the foregoing heat dissipation device 100 in practical applications; on the other hand, the structural complexity of the flow guide member 110 can be reduced, thereby saving the manufacturing cost and manufacturing difficulty of the flow guide member 110, which is beneficial to reducing the use cost of the foregoing heat dissipation device 100; on the one hand, the method of opening the foregoing air outlet passage and air outlet 102 on the rib portion 112 is beneficial to further reducing the cross-sectional area of the air flow when flowing out of the flow guide member 110, thereby increasing the air flow velocity, and can increase the position difference between the air outlet and the flow passage, which is convenient to more flexibly design the shape of the flow guide member 110 in combination with the actual situation of the vehicle, and further ensure the assembly convenience of the flow guide member 110.

[0056] It can be understood that the rib portion 112 and the cylindrical body portion 111 can be an integral structure, so that in practical applications, the flow guide member 110 can be manufactured by an integral molding method, reducing the assembly difficulty and structural gaps of the flow guide member 110, which is beneficial to reducing the risk of gas penetration in the flow guide member 110.

[0057] It can be understood that the aforementioned mounting wall can be used to detachably connect to one end of the battery pack 300, thereby facilitating the disassembly and maintenance of the flow guide member 110. Exemplarily, the mounting wall can be provided on the front end wall 301 of the aforementioned battery pack 300.

[0058] It can be understood that the two ends of the aforementioned cylindrical body portion 111 refer to the two ends of the cylindrical body portion 111 in the axial direction, and the circumferential side of the aforementioned cylindrical body portion 111 refers to the outer wall between the two ends of the cylindrical body portion 111.

[0059] As Figure 2 and Figure 3 shown, in some examples, the heat dissipation device 100 applied to a vehicle further includes: a seal 130, one side of the seal 130 is provided on the mounting wall, and the other side is used to be provided on one end of the battery pack 300. A cleaning port 104 is formed on the mounting wall, and the cleaning port 104 is communicated with the air passing channel 103; wherein, the seal 130 is used to cover or open the cleaning port 104; or the seal 130 is arranged around the cleaning port 104.

[0060] In this technical solution, the aforementioned heat dissipation device 100 may further include the aforementioned seal 130, and the mounting wall of the cylindrical body portion 111 may be provided with the aforementioned cleaning port 104; based on the aforementioned settings, on the one hand, the cleaning port 104 can cooperate with the aforementioned air inlet 101 to provide more ways for the internal cleaning of the cylindrical body portion 111, thereby improving the cleaning convenience of the cylindrical body portion 111 and reducing the risk of blockage of the air passing channel 103; on the other hand, the mounting wall can be connected to one end of the battery pack 300 through the aforementioned seal 130, and when the seal 130 is connected to one end of the battery pack 300, the flow guide member 110 can use the seal 130 to block the cleaning port 104 or block the gap between the mounting wall and the battery pack 300, thereby avoiding the airflow from discharging through the cleaning port 104, which is beneficial to reducing gas loss and ensuring the output flow rate of the air outlet 102, and further guaranteeing the heat dissipation effect.

[0061] It can be understood that when the seal 130 is used to cover or open the cleaning port 104, the seal 130 can be an elastic gasket. When the seal 130 covers the aforementioned cleaning port 104, it can also play a role in isolating the dirt in the battery pack 300 and the air passing channel 103, avoiding the dirt in the air passing channel 103 from impacting or wearing the battery pack 300, thereby further avoiding the soiling of the battery pack 300, which is beneficial to further improving the safety and reliability of the aforementioned heat dissipation device 100. When the seal 130 is arranged around the cleaning port 104, the seal 130 can be a sealing ring.

[0062] It can be understood that the aforementioned seal 130 can be used to detachably connect to one end of the battery pack 300, thereby facilitating the disassembly and maintenance of the flow guide member 110. Exemplarily, the seal 130 can be connected to the front end wall 301 of the aforementioned battery pack 300.

[0063] In some examples, both the cylindrical body portion 111 and the rib portion 112 are made of a metal material, and the mounting wall is used for heat transfer connection to one end of the battery pack 300.

[0064] In this technical solution, both the cylindrical body portion 111 and the rib portion 112 can be made of a metal material, and the mounting wall can be used for heat transfer connection to one end of the battery pack 300. Based on the foregoing settings, on the one hand, the end of the cylindrical body portion 111 where the mounting wall is formed can be a closed end, so as to avoid the gas in the air passage 103 flowing out through paths other than the air outlet 102, which is beneficial to reducing gas loss and ensuring the output flow rate of the air outlet 102; on the other hand, the flow guide member 110 can absorb the heat of the battery pack 300 by means of heat conduction and dissipate the heat to the external environment, which is beneficial to further enriching the heat dissipation method of the aforementioned heat dissipation device 100 for the battery pack 300 and improving the heat dissipation effect on the battery pack 300.

[0065] Exemplarily, both the cylindrical body portion 111 and the rib portion 112 are made of stainless steel or aluminum. The aforementioned aluminum can be, but is not limited to, aluminum alloy, aluminum matrix composite material, etc.

[0066] As Figures 1 to 3 shown, in some examples, the number of rib portions 112 is multiple, and the multiple rib portions 112 are arranged at intervals along the circumferential direction of the cylindrical body portion 111. When the mounting wall is disposed at one end of the battery pack 300, along the height direction of the vehicle, the position height of at least part of the rib portions 112 is lower than the position height of the air passage 103.

[0067] In this technical solution, the number of the ribbed portions 112 can be set to be multiple, and the multiple ribbed portions 112 are arranged at intervals along the circumferential direction of the cylindrical body portion 111. Correspondingly, the aforementioned air outlet channels and air outlets 102 can be provided in each of the multiple ribbed portions 112. Based on the aforementioned settings, the heat dissipation assembly can output air flow through the multiple air outlets 102, thereby facilitating multi-directional air supply to the battery pack 300, which is beneficial to further expanding the contact area between the air flow and the battery pack 300 and improving the heat dissipation efficiency of the battery pack 300. When the installation wall is provided at one end of the battery pack 300, the position height of at least some of the ribbed portions 112 can be set to be lower than the position height of the air passage 103. Thus, if there is dirt in the air passage 103, it is convenient for the dirt to move into the ribbed portions 112 with a lower position and be discharged through the air outlets 102 of the corresponding ribbed portions 112, which is beneficial to reducing the accumulation of dirt in the flow guide member 110, avoiding damage to the battery pack 300 caused by dirt, and reducing the cleaning burden of the aforementioned heat dissipation device 100.

[0068] It can be understood that the circumferential direction of the aforementioned cylindrical body portion 111 refers to the direction around the axis of the cylindrical body portion 111.

[0069] As Figure 1 shown, in some examples, the filter element 120 includes: a support frame 121, which is provided at one end of the flow guide member 110, and the support frame 121 is arranged around the air inlet 101; a plurality of air guide strips 122, which are arranged at intervals inside the support frame 121; wherein, the support frame 121 protrudes from the circumferential side of the flow guide member 110, the flow guide member 110 is used to pass through the wheel housing 210 of the vehicle, and the support frame 121 is used to abut and cooperate with the wheel housing 210.

[0070] In this technical solution, the filter element 120 can be a grid-like structure including the aforementioned support frame 121 and a plurality of the aforementioned air guide strips 122. Based on the aforementioned settings, the filter element 120 can use the aforementioned air guide strips 122 to intercept dirt, reducing the risk of dirt entering the flow guide member 110, thereby improving the cleanliness of the air flow output from the air outlet 102 and reducing the risk of soiling of the battery pack 300. In actual application, the wheel housing 210 of the vehicle can be provided with an installation opening, and the flow guide member 110 can pass through the aforementioned wheel housing 210 through the aforementioned installation opening. Correspondingly, the support frame 121 can abut and cooperate with the wheel housing 210, so that the aforementioned heat dissipation device 100 is clamped at the aforementioned installation opening, facilitating the fixation of the aforementioned heat dissipation device 100 on the vehicle body 200, and further improving the installation stability of the aforementioned heat dissipation device 100.

[0071] It can be understood that the support frame 121 is provided at the end of the flow guide member 110 where the aforementioned air inlet 101 is formed.

[0072] Exemplarily, the support frame 121 and the flow guide member 110 can be of an integral structure.

[0073] As shown Figures 1 to 3 In some examples, the heat dissipation device 100 applied to a vehicle further includes: a first fixing member 140 disposed on the flow guiding member 110; a second fixing member 150 for being disposed on the battery pack 300, and the first fixing member 140 is adapted to be in limit cooperation with the second fixing member 150.

[0074] In this technical solution, the heat dissipation device 100 may further include the first fixing member 140 and the second fixing member 150; based on the foregoing setting, the heat dissipation device 100 can be fixedly installed on the battery pack 300 through the first fixing member 140 and the second fixing member 150, so as to improve the installation stability of the heat dissipation device 100.

[0075] It can be understood that the connection relationship between the first fixing member 140 and the second fixing member 150 is detachable. When the first fixing member 140 is connected to the second fixing member 150, the first fixing member 140 is in limit cooperation with the second fixing member 150, so as to facilitate the disassembly and assembly of the heat dissipation device 100 relative to the battery pack 300.

[0076] Exemplarily, one of the first fixing member 140 and the second fixing member 150 may be a card slot, and the other may be a buckle adapted to the foregoing card slot.

[0077] Exemplarily, the first fixing member 140 and the flow guiding member 110 may be an integral structure. In practical applications, the second fixing member 150 can be fixedly installed on the battery pack 300.

[0078] In some feasible examples, the heat dissipation device 100 applied to a vehicle further includes a control member and an adjusting member; wherein, the adjusting member is used to adjust the opening degree of the foregoing air inlet 101, the control member is signal-connected to the adjusting member, and is used to control the operation of the adjusting member; based on the foregoing setting, the heat dissipation device 100 can use the adjusting member to open or close the foregoing air inlet 101, or adjust the conduction area of the air inlet 101, so as to realize the adjustment of the gas flow rate of the air inlet 101, which is beneficial to improving the controllability of the heat dissipation effect of the heat dissipation device 100 on the battery pack 300. And, in practical applications, when the vehicle is in a stopped state, the adjusting member can be controlled to close the foregoing air inlet 101, so as to avoid dirt in the external environment from entering the flow guiding member 110, which is beneficial to ensuring the cleanliness inside the flow guiding member 110 and reducing the risk of dirt damage to the battery pack 300.

[0079] It can be understood that there can be various forms of the aforementioned adjusting member. For example, the adjusting member can include a baffle rotatably arranged at the air inlet 101 and a driving member for driving the baffle to rotate. During the rotation of the baffle, the angle between the baffle and the plane where the air inlet 101 is located will change, so that the covering degree of the baffle on the air inlet 101 will change accordingly, and then the opening degree adjustment of the air inlet 101 can be realized. In addition to the form of the adjusting member given in the foregoing example, other forms of adjusting members can also be adopted, as long as the opening degree adjustment of the air inlet 101 can be realized, and no excessive limitation is made here.

[0080] Exemplarily, the aforementioned control member can include a first acquisition module and a first control module. Among them, the first acquisition module is used to acquire the vehicle speed information of the vehicle, and the first control module is used to control the operation of the adjusting member according to the aforementioned vehicle speed information, so that the opening degree of the air inlet 101 increases with the increase of the vehicle speed or decreases with the decrease of the vehicle speed. Based on the foregoing setting, the air inlet 101 can have a larger opening degree when the vehicle speed is relatively high, so as to facilitate the heat dissipation device 100 applied to the vehicle to deliver more air flow to the battery pack 300 to improve the heat dissipation efficiency of the battery pack 300, or have a smaller opening degree when the vehicle speed is relatively low, so as to reduce the risk of dirt entering the guide member 110.

[0081] Exemplarily, the aforementioned control member can include a second acquisition module and a second control module. Among them, the second acquisition module is used to acquire the real-time weather information of the environment where the vehicle is located, and the second control module is used to control the adjusting member to close the air inlet 101 when the real-time weather is rainy or the vehicle speed is equal to 0, or control the adjusting member to open the air inlet 101 when the real-time weather is non-rainy and the vehicle speed is greater than 0. Based on the foregoing setting, when the vehicle is driving or stopped in rainy weather, the air inlet 101 can be closed to avoid sewage and / or dirt on the road surface from entering the guide member 110 and reduce the risk of soiling of the battery pack 300, or when the vehicle is driving in non-rainy weather, the air inlet 101 can be opened to facilitate the heat dissipation device 100 applied to the vehicle to dissipate heat from the battery pack 300.

[0082] As Figure 5 and Figure 6 As shown, according to the second aspect of the embodiments of the present disclosure, a vehicle is proposed, including: a vehicle body 200; wheels 400 rotatably arranged on the vehicle body 200; a battery pack 300 arranged on the vehicle body 200; a heat dissipation device 100 applied to the vehicle as proposed in any one of the foregoing first aspects, a guide member 110 is arranged on the vehicle body 200, and an air inlet 101 is arranged behind the wheels 400 to access the air flow around the wheels 400 when the wheels 400 rotate, and an air outlet 102 is arranged corresponding to the battery pack 300.

[0083] The vehicle provided by the embodiments of the present disclosure includes the aforementioned vehicle body 200, wheels 400, battery pack 300, and the heat dissipation device 100 applied to the vehicle as claimed in any one of the first aspects above; based on the aforementioned settings, the heat dissipation device 100 applied to the vehicle can introduce the airflow near the wheels 400 into the air passage 103 through the air inlet 101 of the flow guide member 110 during the driving of the vehicle, and discharge the airflow to the battery pack 300 through the air outlet 102 of the flow guide member 110. When the battery pack 300 comes into contact with the airflow, heat exchange can occur. Thus, the heat dissipation device 100 can continuously supply airflow to the battery pack 300 during the driving of the vehicle, thereby improving the heat dissipation rate of the battery pack 300, reducing the temperature of the battery pack 300, and moreover, the heat dissipation device 100 does not require the battery pack 300 to provide energy during the process of supplying air to the battery pack 300. It can improve the heat dissipation effect on the battery pack 300 while avoiding increasing the energy consumption of the battery pack 300, providing guarantee for the cruising range of the vehicle; the filter member 120 of the heat dissipation device 100 can filter the airflow flowing through the air inlet 101 to intercept the dirt mixed in the airflow, reducing the risk of the dirt being discharged to the battery pack 300 through the air outlet 102, which is beneficial to avoiding the contamination of the battery pack 300 and can improve the safety and reliability of the heat dissipation device 100.

[0084] It can be understood that based on the aforementioned settings, the heat dissipation assembly can also guide and straighten the airflow near the wheels 400 during the driving of the vehicle, thereby reducing the wind resistance of the wheels 400, which is beneficial to further reducing the energy consumption of the vehicle.

[0085] It should be noted that the aforementioned vehicle can be, but is not limited to, new energy vehicles, hybrid vehicles, etc.

[0086] Exemplarily, such as Figure 5 and Figure 6As shown, in practical applications, the heat dissipation device 100 applied to a vehicle can be connected to the aforementioned vehicle body 200 and battery pack 300 to facilitate the installation and fixation of the heat dissipation device 100 and improve the stability and reliability of the heat dissipation device 100. Specifically, one end of the flow guide member 110 where the air inlet 101 is formed can be arranged on the wheel housing 210 of the vehicle body 200. For example, the flow guide member 110 can penetrate through the wheel housing 210, and one end of the flow guide member 110 where the air outlet 102 is formed can be arranged on the battery pack 300; the air inlet 101 can be flush with the wheel housing 210 or located between the wheel housing 210 and the wheel 400, and the air inlet 101 faces the circumferential side of the wheel 400, so that the air inlet 101 is arranged corresponding to the aforementioned wheel 400 and is convenient for accessing the air flow near the wheel 400 when the wheel 400 rotates. Among them, when the air inlet 101 is flush with the wheel housing 210, a relatively large spacing distance can be formed between the heat dissipation device 100 and the wheel 400, avoiding interference between the wheel 400 and the heat dissipation device 100 and being beneficial to improving the concealment of the heat dissipation device 100 and providing guarantee for the aesthetics of the vehicle; the air outlet 102 can be arranged close to the battery pack 300, and the conduction direction of the air outlet 102 can intersect or be parallel to at least one side wall of the battery pack 300, so that the air outlet 102 is arranged corresponding to the aforementioned battery pack 300 and is convenient for the air flow output from the air outlet 102 to contact the battery pack 300 to dissipate heat from the battery pack 300. Among them, when the conduction direction of the air outlet 102 is parallel to at least one side wall of the battery pack 300, it is convenient for the air flow output from the air outlet 102 to flow in a direction parallel to this side wall, thereby reducing the change in the flow direction of the air flow and the loss of kinetic energy, being beneficial to ensuring the air flow speed on the surface of the battery pack 300 and improving the heat dissipation efficiency of the battery pack 300.

[0087] It can be understood that the battery pack 300 can be generally cuboid-shaped. Correspondingly, the outer surface of the battery pack 300 can include a front end wall 301 and a rear end wall that face away from each other in the length direction, a left side wall 302 and a right side wall that face away from each other in the width direction, and an upper side wall 303 and a lower side wall that face away from each other in the height direction. In practical applications, the length direction, width direction, and height direction of the battery pack 300 can respectively match the length direction, width direction, and height direction of the vehicle body 200. The aforementioned upper side wall 303 is arranged towards the roof, the aforementioned front end wall 301 is arranged towards the vehicle head, the aforementioned left side wall 302 is arranged close to the driver's door, and the width of the battery pack 300 is greater than the height of the battery pack 300 and less than the length of the battery pack 300. Thus, the area of each side wall of the battery pack 300 is larger than that of the aforementioned front end wall 301 and rear end wall; the conduction direction of the air outlet 102 can intersect or be parallel to at least one side wall of the battery pack 300, that is to say, the conduction direction of the air outlet 102 can intersect or be parallel to at least one of the aforementioned upper side wall 303, lower side wall, left side wall 302, and right side wall. Based on this, it is convenient for the air flow to contact at least one of the aforementioned side walls and flow along the corresponding side wall after flowing out of the air outlet 102, which is beneficial to increasing the contact area between the air flow and the battery pack 300 and further improving the heat dissipation effect of the heat dissipation component on the battery pack 300.

[0088] Exemplarily, as Figure 5 shown, in practical applications, the flow guide member 110 can be arranged behind the wheel 400, and the air inlet 101 can be arranged towards the periphery of the wheel 400, so as to facilitate the air inlet 101 to access the air flow around the wheel 400 during vehicle driving and be beneficial to the air flow output by the air outlet 102. It can be understood that the area behind the wheel 400 refers to the area between the wheel 400 and the vehicle tail. Specifically, considering that the battery pack 300 is usually located between the front wheel and the rear wheel of the vehicle, the air inlet 101 can be arranged behind the front wheel of the vehicle, the air outlet 102 can be arranged close to the front end wall 301 of the battery pack 300, and the conduction direction of the air outlet 102 can be consistent with the length direction of the battery pack 300, so as to facilitate the arrangement of the air inlet 101 and the air outlet 102 in the direction from the vehicle head to the vehicle tail, which is beneficial to making the flow direction of the air flow in the air passage 103 and the flow direction of the air flow output by the air outlet 102 conform to the gas pressure gradient in the external environment during vehicle driving, improving the gas flow rate in the air passage 103 and the flow velocity of the air flow output by the air outlet 102, further enhancing the heat dissipation effect of the heat dissipation component on the battery pack 300, and being beneficial to shortening the distance between the heat dissipation component and the battery pack 300, reducing the length requirement for the air passage 103, improving the structural compactness of the aforementioned heat dissipation device 100, reducing the overall volume of the aforementioned heat dissipation device 100 and the requirement for the installation space, and being beneficial to realizing the concealed installation of the aforementioned heat dissipation device 100.

[0089] AsFigure 5 As shown, in some examples, in the height direction of the vehicle body 200, the position height of at least part of the air inlet 101 is lower than the position height of the axis of the wheel 400.

[0090] In this technical solution, the position height of at least part of the air inlet 101 can be set to be lower than the position height of the axis of the wheel 400; based on the foregoing setting, the air inlet 101 can be made closer to the bottom of the wheel 400, so that the airflow rolled up when the wheel 400 rotates can enter the air inlet 101 more quickly, which is beneficial to increasing the gas flow rate in the heat dissipation device 100 and improving the heat dissipation effect on the battery pack 300.

[0091] It should be noted that Figure 5 the four directions of up, down, front, and back shown in are respectively used to schematically represent the up direction, down direction, front direction, and back direction of the vehicle body.

[0092] In addition, since the vehicle provided by the embodiments of the present disclosure includes the heat dissipation device 100 applied to the vehicle as proposed in any one of the above first aspects, it thus has all the beneficial effects of the heat dissipation device 100, which will not be elaborated here.
