[0035] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] The heat dissipation structure 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0037] like Figure 1 , Figure 6 and Figure 7 As shown, the heat dissipation structure 100 according to the embodiment of the utility model is used in a vehicle 1000 , and the heat dissipation structure 100 includes an air duct member 1 and a heat dissipation module 2 .

[0038] Specifically, the air duct member 1 has an air duct 14, a first air inlet 11 and an air outlet 13, the first air inlet 11 and the air outlet 13 are connected to the air duct 14, the first air inlet 11 is located at the front side of the air duct member 1 along the front-rear direction of the vehicle 1000, the air outlet 13 is located at the rear side of the air duct member 1 along the front-rear direction of the vehicle 1000, and the heat dissipation module 2 is arranged in the air duct 14. Therefore, the airflow (for example, cooling air) can enter the air duct member 1 from the first air inlet 11, so that the airflow can exchange heat with the heat dissipation module 2 to take away the waste heat inside the heat dissipation module 2, and flow out from the air outlet 13 to meet the heat dissipation demand of the front end of the vehicle 1000.

[0039] In addition, if Figure 6 and Figure 7As shown, the air duct member 1 also has a second air inlet 12, which is connected to the air duct 14. The second air inlet 12 is located at the lower side of the air duct member 1 along the up-down direction of the vehicle 1000, and the heat dissipation module 2 is located at the rear side of the second air inlet 12 along the front-back direction of the vehicle 1000. Therefore, the airflow entering from the first air inlet 11 and the second air inlet 12 can flow to the heat dissipation module 2, which can increase the air intake volume at the front end of the vehicle 1000, thereby increasing the effective air intake area of ​​the heat dissipation module 2, improving the heat exchange efficiency of the heat dissipation module 2, improving the heat dissipation capacity, and enhancing the heat dissipation performance of the vehicle 1000, which can meet the use requirements of the vehicle 1000 in a high temperature environment, and avoid making other shape changes to the front end of the vehicle 1000, which can reduce the development cost.

[0040] At the same time, if Figure 6 and Figure 7 As shown, the heat dissipation structure 100 also includes an air guide structure 3, which is arranged at the second air inlet 12. The air guide structure 3 can open or close the second air inlet 12, and realize the need to control the opening or closing of the second air inlet 12 in different situations, so as to adjust the air intake volume entering the front end of the vehicle 1000, and meet the air intake volume requirements of the heat dissipation module 2 in different situations. In addition, when the air guide structure 3 closes the second air inlet 12, it can prevent impurities from entering the interior of the vehicle 1000 through the second air inlet 12, ensuring the safety and reliability of the interior of the vehicle 1000.

[0041] According to the heat dissipation structure 100 of the embodiment of the utility model, the first air inlet 11 is located at the front side of the air duct member 1 along the front-to-rear direction of the vehicle 1000, and the second air inlet 12 is located at the lower side of the air duct member 1 along the up-down direction of the vehicle 1000. The heat dissipation module 2 is arranged in the air duct 14, so that the air flow can enter the air duct 14 through the first air inlet 11 and the second air inlet 12, thereby effectively increasing the air intake at the front end of the vehicle 1000, increasing the effective air intake area of ​​the heat dissipation module 2, and improving the heat exchange efficiency of the heat dissipation module 2. The air guide structure 3 is arranged at the second air inlet 12, which can control the opening or closing of the second air inlet 12 under different conditions, meet the air intake of the heat dissipation module 2 in different situations, and improve the heat dissipation capacity of the vehicle 1000.

[0042] In some embodiments of the present invention, Figure 2-Figure 4 As shown, the air guide structure 3 includes a fixed frame 31, which is arranged at the second air inlet 12, and the fixed frame 31 is connected to the air duct member 1, so as to realize the connection requirement between the air guide structure 3 and the air duct member 1, and the fixed frame 31 has an inlet, so that the airflow can enter the air duct 14 through the inlet, thereby realizing the requirement of the airflow entering the air duct 14 from the second air inlet 12.

[0043] In addition, if Figure 2-Figure 4As shown, the wind guide structure 3 also includes a wind guide blade 32, one end of which is connected to the fixed frame 31, and the other end of which can swing, so that the wind guide blade 32 can open or close the inlet of the fixed frame 31, thereby opening or closing the second air inlet 12. The wind guide structure 3 has a simple structure for opening or closing the second air inlet 12, which is easy to control. At the same time, when the wind guide blade 32 opens the inlet, the airflow can enter the air duct 14 through the guidance of the wind guide blade 32, ensuring smooth airflow and reducing the air inlet resistance.

[0044] In the embodiment of the utility model, the specific structure for controlling the swing of the wind guide blade 32 can be set according to actual conditions.

[0045] For example, in some embodiments, the heat dissipation structure 100 may include a driving device, which can drive the other end of the air guide blade 32 to swing, thereby opening or closing the second air inlet 12 to meet the air intake requirements of the heat dissipation module 2 under different conditions.

[0046] For example, in some embodiments, Figure 6 and Figure 7 As shown, the heat dissipation structure 100 may include a heat dissipation fan 4, which is disposed in the air duct 14 and is located on a side of the heat dissipation module 2 facing the air outlet 13 (eg Figure 6 The heat dissipation module 2 can be cooled by the cooling fan 4 to ensure a good cooling effect at the front end of the vehicle 1000, and the airflow of the air duct 14 can be changed and controlled by controlling the cooling fan 4.

[0047] At the same time, by controlling the cooling fan 4, the air pressure in the air duct 14 can be adjusted, so that the free end of the air guide blade 32 can open or close the second air inlet 12 under the action of the air pressure in the air duct 14, and the swing of the other end of the air guide blade 32 can be controlled, which makes the control simple and avoids the use of other drive structures for control, which is conducive to reducing production costs.

[0048] In addition, when the free end of the air guide blade 32 opens the second air inlet 12 under the action of the air pressure in the air duct 14, the air flow can enter the air duct 14 through the second air inlet 12, increasing the air intake in the air duct 14, thereby improving the heat dissipation capacity of the heat dissipation structure 100, effectively reducing the load of the heat dissipation fan 4, and reducing energy consumption, thereby achieving the effect of energy saving and consumption reduction.

[0049] For example, Figure 6As shown, when the heat dissipation demand at the front end of the vehicle 1000 is large, for example, in a high temperature environment, the heat dissipation demand at the front end of the vehicle 1000 is large due to the vehicle 1000 idling in situ, driving at a low speed, urban working conditions (the vehicle 1000 is congested or stops and starts, etc.), and climbing a hill at a low speed, the cooling fan 4 is controlled to run at a high speed, and the air flow can be sucked into the air duct 14 from the first air inlet 11. Since the area of ​​the first air inlet 11 is small, the air intake is insufficient, resulting in negative pressure in the air duct 14, so that the air guide blade 32 is sucked by the negative pressure, and the free end of the air guide blade 32 is automatically opened, that is, the air guide blade 32 can open the second air inlet 12, so that the air flow can enter the air duct 14 through the first air inlet 11 and the second air inlet 12, meeting the required air intake demand, and the air flow in the air duct 14 can enter the heat dissipation module 2 for heat exchange, and the air flow after heat exchange is discharged from the air outlet 13 through the cooling fan 4, meeting the heat exchange demand of the heat dissipation module 2, which is beneficial to improving the heat exchange efficiency of the heat dissipation module 2. For example, the flow path of the air flow is Figure 6 Indicated by the arrow.

[0050] like Figure 7 As shown, when the vehicle 1000 is traveling at high speed, due to the high speed, the air volume entering the air duct 14 from the first air inlet 11 is large enough to meet the heat exchange requirements of the heat dissipation module 2, and the heat dissipation fan 4 is controlled not to work. At the same time, the airflow entering from the first air inlet 11 forms a positive pressure in the air duct 14, and the air guide blade 32 is affected by the positive pressure, and the free end of the air guide blade 32 is automatically closed, that is, the air guide blade 32 can close the second air inlet 12, so that the airflow can only enter the air duct 14 through the first air inlet 11, and the airflow in the air duct 14 can enter the heat dissipation module 2 for heat exchange, and the airflow after heat exchange is discharged from the air outlet 13 through the heat dissipation fan 4, so as to meet the heat exchange requirements of the heat dissipation module 2. For example, the flow path of the airflow is as follows: Figure 7 Indicated by the arrow.

[0051] In some embodiments of the present invention, Figure 2 As shown, the air guide blade 32 is located above the fixed frame 31 along the up and down direction of the vehicle 1000. Along the front and back direction of the vehicle 1000, the front end of the air guide blade 32 is rotatably connected to the fixed frame 31, and the rear end of the air guide blade 32 can swing up and down relative to the front end. Therefore, when the air guide blade 32 opens the second air inlet 12, it is convenient for the airflow to enter the air duct 14 from the second air inlet 12, avoiding the air guide blade 32 from blocking the flow of the airflow, thereby ensuring smooth flow of the airflow.

[0052] In addition, if Figure 2As shown, there are multiple (greater than or equal to two) spaced apart support ribs 311 in the inlet. When the air guide structure 3 closes the second air inlet 12, the air guide blades 32 and the support ribs 311 stop each other, so that the support ribs 311 can support the air guide blades 32, ensuring that the air guide blades 32 are supported reliably, avoiding deformation and collapse of the air guide blades 32, and preventing the air guide blades 32 from swinging downward and affecting the normal driving of the vehicle 1000.

[0053] In some embodiments of the present invention, Figure 2 , Figure 3 and Figure 4 As shown, the air guide blade 32 is snap-connected with the fixed frame 31 , so that the air guide blade 32 and the fixed frame 31 are reliably connected, and the installation or removal between the air guide blade 32 and the fixed frame 31 is facilitated, and the movable space of the free end of the air guide blade 32 can be reserved.

[0054] In some embodiments, a clamping hole is provided on one end of the air guide blade 32 and one of the fixed frame 31, and a clamping protrusion is provided on the other, that is, a clamping hole is provided on one end of the air guide blade 32, and a clamping protrusion is provided on the fixed frame 31; or, a clamping protrusion is provided on one end of the air guide blade 32, and a clamping hole is provided on the fixed frame 31. Through the cooperation of the clamping hole and the clamping protrusion, it can be ensured that the air guide blade 32 and the fixed frame 31 are reliably fixed, and the structure is simple, which is convenient for processing and manufacturing.

[0055] In some embodiments, when the air guide blade 32 is snap-connected to the fixed frame 31, the free end of the air guide blade 32 can swing within a certain range, which can prevent the air guide blade 32 from swinging too much and colliding with the air duct member 1 to cause abnormal noise and other problems, thereby protecting the safety and reliability of the air duct member 1 and extending its service life.

[0056] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, there are multiple air guide blades 32, and the multiple air guide blades 32 are arranged along the front and rear direction of the vehicle 1000. The multiple air guide blades 32 can guide the airflow entering from the second air inlet 12 to ensure smooth airflow, and can further increase the air intake volume in the air duct 14, which is beneficial to improving the heat dissipation performance of the vehicle 1000.

[0057] In the embodiment of the utility model, the number of the air guide blades 32 can be flexibly set according to actual conditions. For example, the air guide blades 32 can be as follows: Figure 3 Three are shown, but there may also be two, four, five, six or more, all of which are within the protection scope of the present utility model.

[0058] In some embodiments of the present invention, Figure 5 As shown, along the thickness direction of the wind guide blade 32 (for example Figure 5 ), the air guide blade 32 includes a sealing sheet 321 and a vibration-damping and noise-reducing sheet 322 which are stacked. When the air guide blade 32 closes the second air inlet 12, the vibration-damping and noise-reducing sheet 322 is located below the sealing sheet 321. Thus, the vibration-damping and noise-reducing sheet 322 can prevent the air guide blade 32 from colliding with other structures when it is closed, causing problems such as abnormal noise, and the sealing sheet 321 can prevent the air flow in the air duct 14 from flowing out of the second air inlet 12, affecting the heat dissipation performance of the vehicle 1000.

[0059] In some embodiments of the present invention, the sealing sheet 321 and the vibration-damping and sound-absorbing sheet 322 are bonded and connected to ensure that the sealing sheet 321 and the vibration-damping and sound-absorbing sheet 322 are reliably connected, and the bonding operation is simple and easy to install, thereby improving assembly efficiency.

[0060] For example, in some embodiments, the sealing sheet 321 and the vibration-damping and noise-reducing sheet 322 may not be bonded, and the sealing sheet 321 and the vibration-damping and noise-reducing sheet 322 are respectively connected to the fixed frame 31 by snapping, and the vibration-damping and noise-reducing sheet 322 is arranged below the sealing sheet 321 along the up and down direction of the vehicle 1000, and the free ends of the sealing sheet 321 and the vibration-damping and noise-reducing sheet 322 can swing within a certain range. When the air guide blade 32 closes the second air inlet 12, the sealing sheet 321 and the vibration-damping and noise-reducing sheet 322 are not bonded, which can still prevent the air guide blade 32 from colliding with other structures when it is closed and causing abnormal noise, and can prevent the airflow in the air duct 14 from flowing out of the second air inlet 12. In addition, the sealing sheet 321 and the vibration-damping and noise-reducing sheet 322 are not bonded, and the assembly efficiency is higher.

[0061] In some embodiments of the present invention, the sealing sheet 321 may be a rubber sheet or a plastic sheet. The rubber sheet or the plastic sheet has the characteristics of light weight, good flexibility, easy self-recovery after deformation, and no water absorption, and can meet the requirements of light weight, sealing, noise reduction, and shock absorption. Of course, the sealing sheet 321 may also be made of other materials with the same or similar properties.

[0062] In some embodiments of the utility model, the vibration-damping and noise-reducing sheet 322 can be a non-woven fabric or a polyurethane sheet. The non-woven fabric or polyurethane sheet has the characteristics of light weight, good flexibility, easy self-recovery after deformation, no water absorption, and good buffering performance, and can have the effects of light weight, sealing, vibration reduction, noise reduction and noise reduction. When the air guide blade 32 is closed, the vibration-damping and noise-reducing sheet 322 of the non-woven fabric can effectively reduce or eliminate abnormal noise and meet the required use requirements. Of course, the vibration-damping and noise-reducing sheet 322 can also use other materials with the same or similar properties.

[0063] According to the following Figure 1 A vehicle 1000 according to an embodiment of the present invention is described.

[0064] like Figure 1As shown, the vehicle 1000 according to the embodiment of the utility model includes a vehicle body 300, a front bumper 200 and the above-mentioned heat dissipation structure 100. The heat dissipation structure 100 is arranged on the vehicle body 300, and the front bumper 200 is arranged at the front end of the vehicle body 300. The front bumper 200 has an opening, and the opening is opposite to and connected with the first air inlet 11. Therefore, the airflow can enter the air duct 14 through the opening and the first air inlet 11, so that the airflow in the air duct 14 flows to the heat dissipation module 2, and the airflow can exchange heat with the heat dissipation module 2, which can improve the heat exchange efficiency of the heat dissipation module 2, improve the heat dissipation capacity, and enhance the heat dissipation performance of the vehicle 1000.

[0065] In addition, if Figure 1 and Figure 6 As shown, an air inlet grille 201 is provided at the opening, and the air inlet grille 201 can prevent debris from entering the air duct member 1 through the opening, thereby effectively protecting the heat dissipation module 2 or other devices inside the vehicle 1000.

[0066] According to the vehicle 1000 of the embodiment of the utility model, the first air inlet 11 is located at the front side of the air duct member 1 along the front-to-rear direction of the vehicle 1000, the second air inlet 12 is located at the lower side of the air duct member 1 along the up-down direction of the vehicle 1000, and the heat dissipation module 2 is arranged in the air duct 14, so that the air flow can enter the air duct 14 through the first air inlet 11 and the second air inlet 12, thereby effectively increasing the air intake at the front end of the vehicle 1000, increasing the effective air intake area of ​​the heat dissipation module 2, and improving the heat exchange efficiency of the heat dissipation module 2, and the air guide structure 3 is arranged at the second air inlet 12, which can control the opening or closing of the second air inlet 12 under different conditions, meet the air intake of the heat dissipation module 2 in different situations, and improve the heat dissipation capacity of the vehicle 1000.

[0067] In some embodiments, the power of the power system of vehicle 1000 is getting bigger and bigger, which makes the heat dissipation demand at the front end of vehicle 1000 higher and higher. The second air inlet 12 can increase the air intake at the front end of vehicle 1000 to meet the air intake demand of heat dissipation module 2, thereby meeting the power, low wind resistance, economy and fashion of vehicle 1000, and improving the user experience.

[0068] In some embodiments, Figure 1 , Figure 6 and Figure 7 As shown, the vehicle 1000 also includes an air guide cover 15, which is arranged above the second air inlet 12, and the air guide cover 15 is located at the front end of the heat dissipation module 2, the front end of the air guide cover 15 is connected to the air inlet grille 201, and the rear end of the air guide cover 15 is connected to the heat dissipation module 2. The air guide cover 15 can be used to isolate the heat dissipation module 2 from the front cabin of the vehicle 1000 to avoid air leakage or backflow, thereby ensuring a good heat dissipation effect at the front end of the vehicle 1000.

[0069] In some embodiments, an air guide plate is provided in the circumferential direction of the heat dissipation module 2. The air guide plate can be used to isolate the heat dissipation module 2 from the front cabin of the vehicle 1000 and guide the air entering from the first air inlet 11 to avoid air leakage or hot air backflow, thereby ensuring good heat dissipation at the front end of the vehicle 1000.

[0070] In some embodiments of the present invention, the wind guide structure 3 can be arranged on the lower guard plate of the front cabin of the vehicle 1000. For example, the wind guide structure 3 can be installed or integrated on the lower guard plate of the front cabin, so that the wind guide structure 3 has strong compatibility and applicability and can meet different assembly requirements.

[0071] In some embodiments, the front end of the air guide cover 15 and the air inlet grille 201 are sealed together to ensure that the front end of the air guide cover 15 and the air inlet grille 201 are reliably sealed, avoiding airflow from the gap between the air inlet grille 201 and the air guide cover 15, ensuring the air intake in the air duct 14, and improving the heat exchange efficiency of the heat dissipation module 2.

[0072] In some embodiments, the rear end of the air guide cover 15 and the heat dissipation module 2 are sealed together to ensure that the rear end of the air guide cover 15 and the heat dissipation module 2 are reliably sealed, thereby preventing air flow from flowing out from the gap between the air guide cover 15 and the heat dissipation module 2, ensuring the air intake in the air duct 14, and improving the heat exchange efficiency of the heat dissipation module 2.

[0073] In some embodiments, the heat dissipation module 2 is sealed with the heat dissipation fan 4 to ensure that the heat dissipation module 2 and the heat dissipation fan 4 are reliably sealed, so that the airflow after heat exchange with the heat dissipation module 2 is discharged by the heat dissipation fan 4 and discharged from the vehicle 1000 through the air outlet 13, thereby avoiding the airflow after heat exchange flowing in the vehicle 1000 and affecting the vehicle 1000, thereby ensuring the performance of the vehicle 1000.
