Abstract
Description
Technical Field
[0001] The embodiments of the present application relate to the field of vehicle technology, and in particular to an engine heat dissipation structure and a vehicle. Background Art
[0002] The engine of a vehicle is a device that provides power for the vehicle. It converts chemical energy into mechanical energy by burning the fuel in the cylinder and outputs it to moving mechanisms such as wheels. The high-temperature gas generated by the combustion of fuel is discharged from the engine through the engine's exhaust pipe. Therefore, the temperature in the engine exhaust pipe area is usually high.
[0003] In the related art, the exhaust pipe area is auxiliary cooled by a vehicle's own cooling system, such as a coolant circulation system.
[0004] However, in the above-mentioned related technologies, when the vehicle's engine is running at high power, the temperature of the engine exhaust pipe area rises quickly, and the vehicle's own cooling system cannot cool down the exhaust pipe area in time, which can easily affect the normal driving of the vehicle.

[0033] Combine the following Figures 1 to 6 , describing an embodiment of the present application.
[0034] The embodiment of the present application provides a vehicle. It should be noted that the vehicle in the present application may refer to a large car, a small car, a special-purpose car, etc. For example, according to the vehicle model, the vehicle in the present application may be a sedan model, an off-road vehicle model, a multi-purpose vehicle (MPV) model or other models. For a vehicle, generally, there are a bottom guard plate 100, wheels, a power source, and a transmission system arranged between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels to rotate the wheels, thereby driving the vehicle to travel. The bottom guard plate 100 is arranged at the bottom of the vehicle to separate components such as the power source and the transmission system from the road environment, thereby protecting the power source and the transmission system.
[0035] It should be noted that in the embodiment of the present application, for a fuel vehicle, the power source may refer to a fuel engine such as a gasoline engine, a diesel engine, etc. The power source converts chemical energy into mechanical energy by burning fuel. As the power source works, the fuel and air are mixed and burned and then discharged from the power source through the exhaust pipe 501, causing the temperature of the exhaust pipe 501 to gradually increase. If the temperature of the exhaust pipe 501 is too high, the viscosity of the lubricating oil will decrease, which will accelerate the wear of machine parts, reduce engine efficiency, and cause damage to peripheral equipment and other adverse effects.
[0036] The vehicle provided in the embodiment of the present application is provided with an engine heat dissipation structure on the bottom guard plate 100, which is capable of cooling the exhaust pipe 501 during the operation of the vehicle.
[0037] See also Figures 1 to 3 The engine heat dissipation structure includes an air inlet 101 and a guide plate 200 arranged on the bottom guard plate 100 of the vehicle. Along the air flow direction, the air inlet 101 is arranged upstream of the exhaust pipe 501 of the engine 500; the guide plate 200 is connected to the side wall of the air inlet 101 away from the exhaust pipe 501, and the height of the guide plate 200 gradually increases towards the direction close to the exhaust pipe 501.
[0038] In this embodiment, by setting the air inlet 101 on the bottom guard plate 100 of the vehicle, the temperature of the exhaust pipe 501 of the engine 500 rises during the driving of the vehicle. By introducing the airflow to blow through the exhaust pipe 501 above the bottom guard plate 100, the heat dissipation of the exhaust pipe 501 is achieved. The faster the vehicle speed, the better the heat dissipation effect. The guide plate 200 is set to guide the airflow passing through the air inlet 101, so that the airflow rises along the guide plate 200 and enters above the bottom guard plate 100, thereby increasing the air intake and improving the heat dissipation effect. At the same time, the guide plate 200 guides the direction of the airflow so that the airflow is concentrated at the position of the exhaust pipe 501, reducing the situation where the airflow is dispersed to other positions, thereby ensuring the efficient use of the airflow.
[0039] Specifically, in the above embodiment, the air inlet 101 is located on the side of the exhaust pipe 501 close to the front end of the vehicle, the airflow reaches the air inlet 101 along the bottom of the vehicle, and passes through the bottom guard plate 100 from the air inlet 101 into the interior of the vehicle.
[0040] It should be noted that the guide plate 200 can be formed integrally with the bottom guard plate 100. For example, the bottom guard plate 100 without the air inlet 101 is subjected to mold stamping or blanking to form the air inlet 101 on the bottom guard plate 100, and the part of the plate surface corresponding to the air inlet 101 on the bottom guard plate 100 is separated from the bottom guard plate 100, thereby forming a raised guide plate 200 structure. In addition, in some embodiments not shown, the guide plate 200 can also be formed by pre-opening the air inlet 101 on the bottom guard plate 100, and then welding an arc plate or a straight plate to the air inlet 101, thereby forming the guide plate 200 structure.
[0041] In the embodiment of the present application, taking the guide plate 200 as an example, the "windward side" refers to the side of the guide plate 200 that is in direct contact with the airflow, and the "leeward side" refers to the side opposite to the "windward side", that is, the side away from the airflow. The same applies to the guide plate 300 mentioned below.
[0042] In some embodiments of the present application, reference Figures 3 to 5 The guide plate 200 is a curved plate, and the concave surface of the curved plate is located on the leeward side of the guide plate 200 .
[0043] In addition, in the embodiment of the present application, the specific form of the guide plate 200 is not limited. In some embodiments not shown, the guide plate 200 can also be a straight plate with the end pointing to the exhaust pipe 501.
[0044] In this embodiment, the guide plate 200 is set as an arc panel, and the concave surface of the arc panel is located on the leeward side of the guide plate 200, that is, the windward surface of the arc panel is convex outward. When the wind blows over the convex arc surface, affected by the air pressure difference, more airflow will move along the convex surface of the arc panel, thereby attracting more air into the air inlet 101, increasing the air intake of the air inlet 101, and thus improving the heat dissipation effect on the exhaust pipe 501.
[0045] Furthermore, in some embodiments of the present application, a guide plate 300 is connected to the side wall of the air inlet 101 opposite to the guide plate 200 , and the guide plate 300 is extended upward from the air inlet 101 .
[0046] Specifically, in this embodiment, the specific shape and posture of the guide plate 300 are not limited, and the guide plate 300 can guide the airflow so that the airflow flows more accurately to the exhaust pipe 501. Exemplarily, the guide plate 300 can be a straight plate, and in some embodiments not shown, the guide plate 200 can also be a curved plate.
[0047] It should be noted that the guide plate 300 can be integrally formed with the bottom guard plate 100, and the air inlet 101 is formed by the bottom guard plate 100 without the air inlet 101 through a mold stamping or blanking process, and at the same time, the plate body corresponding to the air inlet 101 is separated and tilted upward to form the guide plate 300. In some embodiments not shown, the guide plate 300 can also be formed by connecting the bottom guard plate 100 with the air inlet 101 through fasteners or by welding. The fasteners can be conventional fasteners such as screws and bolts, or they can be fasteners of other shapes designed for installing the guide plate 300.
[0048] In this embodiment, the guide plate 300 is provided to guide the airflow at the air inlet 101 and the airflow guided by the guide plate 200, so that the airflow is concentrated to the exhaust pipe 501, thereby avoiding the waste of the airflow entering the air inlet 101 and further improving the heat dissipation effect.
[0049] It should be further explained that, when the guide plate 300 is a straight plate, the angle between the back of the guide plate 300 and the upper side of the bottom guard plate 100 can be an acute angle or an obtuse angle. When the guide plate 300 and the upper side of the bottom guard plate 100 are at an acute angle, the airflow can be better guided, the air intake volume can be increased, and the heat dissipation effect can be improved. When the guide plate 300 and the upper side of the bottom guard plate 100 are at an obtuse angle, although the airflow guiding effect is slightly weaker, for the bottom guard plate 100 and the guide plate 300 formed in one piece, the mold cost is lower, and it is easy to demold during the processing, which effectively improves the component production capacity.
[0050] Further, in some embodiments of the present application, please refer to Figure 3 , the top of the guide plate 300 is higher than the top of the guide plate 200.
[0051] In this embodiment, by making the height of the top of the guide plate 300 higher than the height of the top of the guide plate 200, the airflow guided through the guide plate 200 is blocked by the guide plate 300 and further changes direction, concentrating in the direction of the exhaust pipe 501, thereby further concentrating the airflow entering the air inlet 101 and improving the heat dissipation effect.
[0052] It should be noted that this embodiment does not limit the horizontal distance between the top of the guide plate 300 and the top of the guide plate 200. The horizontal distance between the top of the guide plate 300 and the top of the guide plate 200 can be used to calculate the air intake based on model simulation, and a distance value with a larger air intake is selected within a certain distance range.
[0053] Further, in some embodiments of the present application, please refer to Figure 3 The angle between the leeward side of the guide plate 300 and the back side of the bottom guard plate 100 is in the range of 70° to 95°.
[0054] In this embodiment, when the angle between the leeward side of the guide plate 300 and the back side of the bottom guard plate 100 is between 95° and 93°, the guide plate 300 can guide the airflow while at the same time, when the guide plate 300 and the bottom guard plate 100 are integrally arranged, the bottom guard plate 100 can be easily demolded and the cost of the mold can be controlled. When the above-mentioned angle is less than 93° and greater than 70°, the guide plate 300 is better at guiding the airflow and can effectively increase the air intake at the air inlet 101.
[0055] Further, in some embodiments of the present application, please refer to Figure 3 The air inlet 101 is connected to the guide plate 200 and the two side walls of the guide plate 300 have the same height.
[0056] In this embodiment, the heights of the two side walls of the air inlet 101 connected to the guide plate 200 and the guide plate 300 are the same. Since the side wall with the guide plate 300 is not higher than the side wall with the guide plate 200, the air intake of the air inlet 101 is guaranteed, thereby ensuring the cooling effect on the exhaust pipe 501. Since the side wall with the guide plate 300 is not lower than the side wall with the guide plate 200, the setting of the air inlet 101 is prevented from affecting the wind resistance of the entire vehicle, affecting the driving speed and fuel consumption.
[0057] Further, in some embodiments not shown in the present application, please refer to Figure 3 , the height of the side wall of the air inlet 101 connected to the guide plate 200 is higher than the height of the side wall of the air inlet 101 connected to the guide plate 300 .
[0058] In this embodiment, by making the side wall height of the guide plate 200 of the air inlet 101 higher than the side wall height of the guide plate 300 of the air inlet 101, the guide plate 300 can efficiently guide and divert the airflow on the lower side of the bottom guard plate 100. Although this will cause the vehicle's wind resistance to increase, it will also greatly increase the air intake of the air inlet 101. At the same time, the guide plate 300 guides the airflow to the exhaust pipe 501, effectively improving the heat dissipation efficiency of the exhaust pipe 501.
[0059] In some of the above embodiments, the side wall of the air inlet 101 with the guide plate 300 can be kept flush with the side wall of the air inlet 101 with the guide plate 200, so as to ensure the air intake of the air inlet 101 without affecting the wind resistance of the whole vehicle; the side wall of the air inlet 101 with the guide plate 300 can also be lower than the side wall of the air inlet 101 with the guide plate 200. In this case, the air intake of the air inlet 101 can be greatly increased by setting the guide plate 300, thereby significantly improving the heat dissipation effect, but at the same time it will also slightly increase the wind resistance of the whole vehicle. Designers can make a choice based on the vehicle type and other actual conditions.
[0060] Further, in some embodiments of the present application, please refer to Figures 4 to 6 The air inlet 101 is located on both side walls of the bottom guard plate 100 in the width direction and is provided with a connecting plate 400 . One end of the connecting plate 400 is connected to the guide plate 200 , and the other end is connected to the guide plate 300 .
[0061] Specifically, in this embodiment, the specific connection method of the connecting plate 400 and the bottom guard plate 100 is not limited. The connecting plate 400 can be formed integrally with the bottom guard plate 100. For example, when the bottom guard plate 100 without the air inlet 101 is stamped or punched to form the air inlet 101, and the guide plate 200 and the guide plate 300 are formed simultaneously, the connecting plate 400 is formed together with the guide plate 200 and the guide plate 300. In some embodiments not shown, the connecting plate 400 can also be connected to the bottom guard plate 100 with the air inlet 101 by fasteners or welding, and the two ends of the connecting plate 400 are respectively abutted against the guide plate 200 and the guide plate 300, and the connecting plate 400 is connected to the guide plate 200 and the guide plate 300 by fasteners or welding. The above-mentioned fasteners can be common fasteners such as screws and bolts, or fasteners of other forms designed separately for installing the connecting plate 400.
[0062] In this embodiment, a connecting plate 400 is provided on the bottom guard plate 100, and one end of the connecting plate 400 is connected to the guide plate 200, and the other end is connected to the guide plate 300, so that the two relatively arranged connecting plates 400, the guide plate 200 and the guide plate 300 are arranged together around the air inlet 101 to prevent the airflow from diffusing above the bottom guard plate 100, so that the airflow is more concentratedly transported toward the exhaust pipe 501. In addition, through the arrangement of the connecting plate 400, the structural strength of the guide plate 200 and the guide plate 300 is enhanced, and it is not easy to bend and deform under higher wind pressure, thereby improving the reliability of the structure.
[0063] Further, in some embodiments of the present application, please refer to Figure 6 The leeward side of the guide plate 200 is provided with a plurality of reinforcing ribs 201, and the plurality of reinforcing ribs 201 are distributed in a grid shape.
[0064] Specifically, the multiple reinforcing ribs 201 include circumferential reinforcing ribs 201 distributed along the circumferential contour of the guide plate 200, transverse reinforcing ribs 201 extending along the width direction of the guide plate 200, and cross reinforcing ribs 201 arranged in groups of two between adjacent transverse reinforcing ribs 201. The circumferential reinforcing ribs 201, the transverse reinforcing ribs 201 and the cross reinforcing ribs 201 together form a grid shape, wherein the circumferential reinforcing ribs 201 are located on both sides of the width direction of the bottom guard plate 100, and the transverse reinforcing ribs 201 and the cross reinforcing ribs 201 all extend to the bottom guard plate 100.
[0065] It should be noted that the reinforcing rib 201 can be integrally provided with the guide plate 200. For example, the reinforcing rib 201 is provided on the bottom guard plate 100 which is not provided with the air inlet 101, and when the bottom guard plate 100 is stamped or punched to form the guide plate 200 and the air inlet 101, part of the reinforcing rib 201 is lifted up along with the guide plate 200 to form the reinforcing rib 201 on the guide plate 200, and the rest of the reinforcing rib 201 remains on the bottom guard plate 100, so that the reinforcing rib 201 extends from the guide plate 200 to the bottom guard plate 100. In some embodiments not shown, the reinforcing rib 201 can also be connected to the bottom guard plate 100 and the guide plate 200 by welding, bonding, etc.
[0066] In this embodiment, by providing a plurality of reinforcing ribs 201, the structural strength of the guide plate 200 is enhanced, and the ability of the guide plate 200 to resist wind pressure is improved, thereby preventing the guide plate 200 from being bent and deformed due to wind pressure during high-speed driving of the vehicle, thereby preventing the guide plate 200 from affecting the airflow diversion effect.
[0067] The effect of an engine heat dissipation structure of the present application is described below in conjunction with the relevant technical situation.
[0068] In the related art, the problem of increased temperature of the vehicle's engine exhaust pipe is usually solved by using the vehicle's own cooling system. However, when the vehicle is running at high speed and the exhaust pipe temperature rises rapidly, the cooling effect of the cooling system is difficult to meet the cooling demand. Some vehicles also set up air inlets on the front side of the vehicle to provide air for the engine's intake while also diverting a portion of the air through the engine exhaust pipe for cooling. However, if the diverted air is too little, it cannot meet the cooling demand. If the diverted air is too much, it will affect the engine's intake volume, resulting in reduced engine efficiency.
[0069] In some of the above embodiments of the present application, an air inlet 101 is provided on the bottom guard plate 100, so that the air on the lower side of the bottom guard plate 100 can enter the top of the bottom guard plate 100 through the air inlet 101 to dissipate heat for the engine 500 and the surrounding structures, and the air entering the top of the bottom guard plate 100 is discharged from the rear or both sides of the vehicle through the interior space of the vehicle. The air inlet 101 is located on the two side walls in the length direction of the bottom guard plate 100, and a guide plate 200 and a guide plate 300 are respectively provided. The surface of the guide plate 200 is set to be an arc-shaped surface, so as to use the pressure difference to guide the air, so that more air enters the air inlet 101 along the surface of the guide plate 300, and the guide plate 300 diverts the air at the air inlet 101 to increase the air intake of the air inlet 101, and also blocks and guides the airflow guided by the guide plate 200, so that the airflow is more concentrated and blown to the designated position of the exhaust pipe 501 of the engine 500 for heat dissipation. During the driving of the vehicle, the vehicle Airflow is naturally formed on the lower side of the vehicle bottom guard plate 100. The faster the vehicle speed is, the faster the temperature rises at the exhaust pipe 501 of the engine 500. The faster the airflow speed is, the higher the air intake volume at the air inlet 101 is, and the heat dissipation effect of the exhaust pipe 501 is further improved. Therefore, the heat dissipation structure of the engine 500 of the present application can well adapt to the situation where the temperature of the exhaust pipe 501 increases during high-speed driving of the vehicle, which makes up for the shortcomings of the vehicle's own cooling system, effectively suppresses the temperature rise of the exhaust pipe 501 of the engine 500, and avoids affecting the normal operation of the vehicle engine 500 and other components.
