The heat dissipation design of the car motor base can indeed effectively reduce the engine temperature to a certain extent.
1. Overview of heat dissipation design of engine bottom guard plate
As an important protective component of the bottom of the automobile engine, the engine bottom guard not only has a protective function, but also affects the heat dissipation characteristics of the engine compartment through its unique design. Through reasonable structural design, the engine bottom guard can optimize the flow field of the entire vehicle and improve the heat dissipation efficiency of the engine compartment.
2. Key thermal design parameters
Folding design: Folding is an important feature of the engine bottom guard. Its angle and shape have a significant impact on heat dissipation performance.
Studies have shown that compared with right-angle folding structures, 45° folding can significantly reduce the turbulence intensity near the folding edge and the temperature inside the folding edge, while increasing the radiator cooling air flow.
Reinforcing rib arrangement: Reinforcing ribs are not only used to enhance the strength of the bottom guard, but also have an important impact on its heat dissipation performance.
The longitudinally arranged reinforcing ribs can more effectively reduce the temperature in the middle of the bottom guard and the turbulence intensity in the upper part, while increasing the radiator air flow.
The height of the transverse stiffeners should be controlled within a certain range (such as within 4mm) to avoid negative effects on the heat dissipation of the engine compartment.
Opening form: The opening form of the bottom guard has a direct impact on the heat dissipation performance.
Compared with oblique openings, flat openings can improve the heat dissipation performance of the engine compartment to a greater extent, reduce the temperature at the opening and the intensity of turbulence above, and increase the radiator air flow.
Although the curved opening has a better effect of isolating external debris, its heat dissipation performance can also be improved by improving the design.
Opening position: The opening position of the bottom guard is also important to the heat dissipation effect.
The best opening positions are usually located on the inclined plate, the front middle and the rear lower part. These positions can more effectively reduce the temperature of the high-temperature area near the bottom guard and reduce the temperature of the radiator inlet and outlet water.
3. The mechanism of heat dissipation design
The heat dissipation design of the engine bottom guard mainly reduces engine temperature by optimizing the flow field of the entire vehicle and improving the heat dissipation efficiency of the engine compartment. Specifically, reasonable folding, reinforcement arrangement, opening form and opening position can guide the air flow through the engine compartment more smoothly and improve the heat dissipation efficiency of the radiator. At the same time, these designs can also reduce the turbulence intensity near the bottom guard and reduce the temperature inside the folds and openings, thereby further reducing the engine temperature.
4. Practical application effects
In practical applications, the heat dissipation design of the engine bottom guard can significantly reduce the temperature of the engine under long-term operation or high-load conditions. This not only improves engine reliability and durability, but also extends engine life. At the same time, good heat dissipation performance also helps improve the vehicle's fuel economy and driving comfort.
To sum up, the heat dissipation design of the car motor base can indeed effectively reduce the engine temperature. Through reasonable design parameters such as edge folding, reinforcement arrangement, opening form and opening position, the flow field of the entire vehicle can be optimized and the heat dissipation efficiency of the engine compartment can be improved. These designs have achieved good results in practical applications, providing a strong guarantee for the reliability and durability of the car.
