Description

Technical Field

[0001] The utility model relates to the technical field of vehicle component cooling, in particular to an air inlet guide piece, an engine compartment and a vehicle. Background Art

[0002] According to the operating conditions of extended-range vehicles, when the vehicle speed is low, the demand operating conditions are low, the engine load is also low, the temperature of the engine components is relatively low, and there is no cooling demand for the engine compartment. When the vehicle speed is high, the engine load is large, the temperature of the various components is also relatively high, and the engine compartment cooling demand is large.

[0003] The existing conventional solution is to cool the entire engine compartment by combining the vehicle's airflow with a cooling fan. The cooling fan is usually turned on only when the water temperature exceeds 90 degrees. In the case of a relatively compact engine compartment, the efficiency of cooling the engine compartment without special guidance of the vehicle's airflow is low. Especially in high temperature environments, the engine compartment temperature is easily high, resulting in the following consequences:

[0004] First, the high temperature of the engine compartment will lead to a higher engine intake temperature, which will bring about adverse effects such as increased tendency of detonation and pre-ignition, causing the engine to enter relevant protection conditions. After entering the protection condition, the engine's fuel consumption will be greatly affected.

[0005] Second, the high temperature in the engine compartment will cause the engine to enter the high-temperature area (above 90 degrees) more frequently, and the fan will start frequently, resulting in an increase in the additional load of the entire vehicle, which indirectly affects the fuel consumption of the entire vehicle.

[0006] Third, the high temperature of the engine compartment will also have a certain impact on the life of the engine's peripheral components. Utility Model Content

[0024] The following describes embodiments of the present invention in detail. 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 intended only to explain the present invention and are not to be construed as limiting the present invention.

[0025] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an air inlet guide 1, which can be installed on a mobile body. In a feasible implementation manner, the mobile body is a vehicle, and the air inlet guide 1 is installed in the engine compartment of the vehicle. During the movement of the vehicle, natural wind can be used to perform directionally cooling treatment on the preset components of the engine in the engine compartment to avoid the preset components from being too hot and affecting the overall temperature of the engine compartment.

[0026] The air inlet guide member 1 includes an air inlet guide portion 2 and an air outlet guide portion 3. The air inlet guide portion 2 and the air outlet guide portion 3 are preferably integrally formed, wherein:

[0027] An air inlet guide cavity 4 is formed in the air inlet guide portion 2, and an air inlet 5 is formed in the air inlet guide cavity 4 on the surface of the air inlet guide member 1. The air inlet 5 is arranged facing the moving direction of the moving body. During the movement of the moving body, the air flow can enter the air inlet guide cavity 4 from the air inlet 5. This air flow is natural wind and does not require additional energy consumption.

[0028] An outlet guide cavity 6 is provided in the outlet guide portion 3. One end of the outlet guide cavity 6 is connected to the inlet guide cavity 4. The other end of the outlet guide cavity 6 forms an outlet 7 on the surface of the inlet guide member 1. The airflow sent out from the outlet 7 can reach the preset components in the moving body, and when passing through the preset components, it removes heat from the preset parts. In the case where the moving body is a vehicle, the preset components can be the supercharger and exhaust manifold on the vehicle's engine. When the vehicle is moving at high speed, natural wind enters from the air inlet 5 of the inlet guide member 1, is guided by the inlet guide cavity 4 and the outlet guide cavity 6, and is sent out from the outlet 7. The natural wind removes heat from the supercharger and exhaust manifold of the engine through heat convection or heat conduction, thereby achieving the purpose of directional cooling. Without increasing the energy consumption of the entire vehicle, it fully ensures that the engine compartment does not overheat, ensuring that the engine can operate more efficiently.

[0029] In the embodiment provided by the present invention, the extension direction of the air inlet guide cavity 4 is parallel to the moving direction of the moving body, and the flow direction of the airflow entering the air inlet guide cavity 4 from the air inlet 5 is parallel to the extension direction of the air inlet guide cavity 4, so that the airflow passes through the air inlet guide cavity 4 smoothly, which can reduce the mutual impact between the incoming airflows, reduce resistance and noise, and at the same time improve the flow efficiency of the airflow.

[0030] Furthermore, the extension direction of the air outlet guide cavity 6 intersects with the moving direction of the moving body, and the flow direction of the air flow flowing out of the air outlet guide cavity 6 from the air outlet 7 is parallel to the direction of gravity. The air flow direction passes through the preset components to be cooled from top to bottom to ensure that the hot air flow is discharged smoothly. When the air inlet guide member 1 is installed to the engine compartment of the vehicle, natural wind enters from the air inlet 5 and is sent out from the air outlet 7 in a vertical state to the preset components of the engine, making full use of the natural wind directional cooling of the vehicle, so that the high-temperature air flow can be discharged from the engine compartment as soon as possible.

[0031] In a feasible embodiment, an arc-shaped wall transition is formed at the junction of the air outlet guide cavity 6 and the air inlet guide cavity 4. The arc-shaped wall is used to guide the turning of the airflow, so that the airflow flows smoothly from the air inlet 5 to the air outlet 7 of the shell, reducing the turbulence and eddy currents of the airflow during the conversion process, thereby improving the uniformity and stability of the airflow, and effectively reducing the noise generated when the airflow passes through the junction of the air outlet guide cavity 6 and the air inlet guide cavity 4, while ensuring that the flow rate in each area at the air outlet 7 is constant, thereby achieving the purpose of uniform air outlet.

[0032] Reference Figure 1As shown, the cross-sections of the air inlet guide cavity 4 and the air outlet guide cavity 6 are both waist-shaped structures, so that the air inlet guide member 1 can ensure the largest possible air flow area within the limited occupied space, ensuring sufficient air intake flow. When the air inlet guide member 1 is applied to a vehicle, it can make full use of the natural wind of the vehicle and carry out directionally cooling of the key high-temperature components of the engine while ensuring the gas flow.

[0033] Based on the air inlet guide member 1 provided in the above embodiment, the utility model also provides an engine compartment, in which an engine and the aforementioned air inlet guide member 1 are arranged, the air inlet 5 of the air inlet guide member 1 is used to introduce natural wind during the vehicle's movement, and the air outlet 7 of the air inlet guide member 1 is arranged relative to the preset components of the engine. The air inlet guide member 1 is located above the engine, and the air flow flowing out of the air outlet guide cavity 6 from the air outlet 7 extends vertically downward. After the natural wind enters from the air inlet 5, it is sent out from the air outlet 7 to the preset components of the engine in a vertical state, making full use of the natural wind directional cooling of the vehicle's travel, allowing the high-temperature airflow to be discharged from the engine compartment as soon as possible, thereby achieving the overall cooling effect of the vehicle without increasing the engine's energy consumption.

[0034] In a feasible embodiment, the preset components include a supercharger and an exhaust manifold, and an air inlet guide 1 is set in the engine compartment to ensure that there is sufficient air intake flow when the vehicle is at high speed. Then, through airflow guidance, the supercharger and exhaust manifold of the engine are concentratedly cooled, and the cooled airflow is guided to be discharged from the engine compartment as soon as possible, which plays a role in draining the overall airflow in the engine compartment. Without increasing the energy consumption of the entire vehicle, it is fully ensured that the engine compartment will not be overheated, ensuring that the engine can work more efficiently.

[0035] In the embodiment provided by the present invention, the provision of an air inlet guide member in the engine compartment creates four beneficial effects:

[0036] 1. The natural airflow of the vehicle is used for cooling, which will not increase the vehicle's energy consumption. The cooling effect is increased by increasing the air intake flow area according to the heat conditions of the preset components, and the cooling effect adapts to the cooling needs of the engine. When the vehicle speed is high, the cooling effect is strong, and the temperature of the corresponding engine components is also high, and the cooling demand is also high. When the vehicle speed is low, the cooling effect is weak, and the temperature of the corresponding engine components is relatively low, and the cooling demand is low.

[0037] 2. After the cooling scheme takes effect, it can effectively reduce the temperature of the engine compartment. When the engine compartment temperature is too high, the intake temperature will increase. When the engine intake temperature is too high, the tendency of engine knock and pre-ignition will increase, causing the engine to enter the corresponding protection strategy, such as adjusting the ignition angle, limiting the EGR opening and other measures. The corresponding protection strategy will have a certain impact on the engine's fuel consumption to varying degrees. Therefore, avoiding excessively high engine compartment temperature can ensure that the engine works efficiently and achieve the purpose of reducing the fuel consumption of the entire vehicle.

[0038] 3. After the cooling solution takes effect, it is equivalent to additionally increasing the cooling capacity of the engine, which can reduce the frequency of the engine water temperature entering the high-temperature area, thereby reducing the frequency of the fan turning on, reducing the additional load of the entire vehicle, and indirectly reducing the fuel consumption of the entire vehicle.

[0039] 4. Avoid the impact of excessive engine compartment temperature on the life of electronic fuel injection components.

[0040] Based on the aforementioned engine compartment, the present invention also provides a vehicle, including the aforementioned engine compartment, wherein the air inlet 5 of the air inlet guide member 1 in the engine compartment is arranged facing the moving direction of the vehicle. When the vehicle is moving at high speed, natural wind enters from the air inlet 5 of the air inlet guide member 1, and is guided by the air inlet guide cavity 4 and the air outlet guide cavity 6, and is sent out from the air outlet 7. The natural wind is used to carry away the heat of the engine's supercharger and exhaust manifold by heat convection or heat conduction, thereby achieving the purpose of directional cooling. Without increasing the energy consumption of the entire vehicle, it is fully ensured that the temperature of the engine compartment is not too high, thereby ensuring that the engine can work more efficiently.

[0041] Furthermore, the extension direction of the air inlet guide cavity 4 of the air inlet guide member 1 is parallel to the moving direction of the vehicle. When the vehicle moves, the flow direction of the airflow entering the air inlet guide cavity 4 from the air inlet 5 is parallel to the extension direction of the air inlet guide cavity 4, so that the airflow passes through the air inlet guide cavity 4 smoothly, which can reduce the mutual impact between the incoming airflows, reduce resistance and noise, and improve the flow efficiency of the airflow.

[0042] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the scope of implementation of the present invention is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present invention.
