Description

Technical Field

[0001] The invention belongs to the technical field of engine heat insulation and relates to a heat insulation cover for an automobile engine. Background Art

[0002] The automobile engine is a key component in propelling the vehicle. Most vehicles utilize a thermal power unit, commonly known as a heat engine. This system converts the heat released by fuel combustion into the mechanical energy required to propel the vehicle through a phase transition of the working fluid. This energy conversion not only determines the vehicle's power performance but also influences its fuel efficiency, operating smoothness, and environmental impact. In modern vehicle designs, a heat shield is often installed above the engine to protect components within the engine compartment from high temperatures.

[0003] At present, the main function of the heat shield is to isolate the large amount of heat generated when the engine is running, preventing this heat from being directly transferred to the engine cover, thereby extending the service life of the engine cover and maintaining its appearance in good condition. However, when in use, the existing heat shield can only simply achieve the function of isolating heat. The temperature inside the engine compartment is also high, which is easy to affect other mechanical components in the engine compartment, thereby affecting the service life of the entire vehicle.

DETAILED DESCRIPTION

[0029] The present invention will be further described below with reference to specific embodiments. It should be noted that, unless otherwise specified or limited, terms such as "dispose," "install," "connect," and "connect" should be understood in a broad sense. For example, "connect" may refer to a fixed connection, a detachable connection, or an integral connection; it may refer to a mechanical connection or an electrical connection; it may refer to a direct connection or an indirect connection through an intermediate medium; or it may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0030] A heat shield for an automobile engine, such as Figures 1-4As shown, it includes a heat insulation cover 1, connecting ears 2, sound insulation cotton 3, a cooling mechanism and an air supply mechanism. Two connecting ears 2 are connected to the front and rear sides of the heat insulation cover 1. The heat insulation cover 1 can be fixed in the engine compartment of the car through the connecting ears 2. A layer of sound insulation cotton 3 is connected to the top of the heat insulation cover 1 to isolate the noise inside the engine. Air outlet holes are evenly spaced at the edge of the heat insulation cover 1. The heat insulation cover 1 is provided with a cooling mechanism for cooling the hot air at the engine and an air supply mechanism for transmitting the hot air.

[0031] like Figure 2-Figure 4 As shown, the cooling mechanism includes a cooling pipe 41, an air guide frame 42, a draft fan 43 and a connecting seat 44. The connecting seats 44 are evenly spaced and connected on both sides of the bottom of the heat insulation cover 1. The cooling pipe 41 is arranged in a reciprocating manner in the heat insulation cover 1. Air guide frames 42 are installed at both ends of the cooling pipe 41. The air guide frames 42 can be fixed in the engine compartment of the car. The draft fans 43 are installed on the air guide frames 42. One of the air guide frames 42 is installed with an intake draft fan 43, and the other air guide frame 42 is installed with an outlet draft fan 43. The operation of the two draft fans 43 can make the gas circulate in the cooling pipe 41. At this time, the heat emitted from the engine is blown to the cooling pipe 41, and the heat can be taken away by the cooling pipe 41 to assist in the cooling process.

[0032] like Figure 4 As shown, a partition net 45 is also included. Both air guide frames 42 are equipped with a partition net 45 to isolate impurities in the engine compartment and prevent impurities from entering the cooling pipe 41 along the air guide frame 42, thereby ensuring the fluidity of the gas in the cooling pipe 41.

[0033] like Figure 3 As shown, the air supply mechanism includes a shielding frame 51 and an air guide fan 52. The shielding frame 51 is connected to the bottom of the heat insulation cover 1, and multiple air guide fans 52 are evenly installed on the top of the shielding frame 51. The operation of the air guide fan 52 can blow the hot air from the engine upward, thereby blowing the hot air to the cooling pipe 41 to assist in cooling the hot air.

[0034] When the engine heat shield 1 is needed, the present engine heat shield 1 can be used. During use, the heat shield 1 is first installed in the engine compartment by connecting the lifting lugs 2 to ensure that the heat shield 1 is located above the engine case. After installation, the two induced draft fans 43 can be started to allow the gas to circulate in the cooling pipe 41, thereby cooling the cooling pipe 41. At the same time, the air guide fan 52 is controlled to operate to blow the hot air emitted from the engine upward. The hot air will pass through the cooling pipe 41, and after being cooled by the cooling pipe 41, it will be discharged outside the heat shield 1. This design can not only effectively isolate the high temperature generated by the engine and prevent heat from being transferred to other components in the engine compartment, but also accelerate the discharge of hot air through forced ventilation and the heat dissipation effect of the cooling pipe 41, thereby avoiding the accumulation of hot air in the engine compartment. In this way, the working efficiency of the engine is improved, the service life of the engine and its surrounding components is extended, and the risk of failure caused by high temperature is reduced. In addition, the design of this heat dissipation system can also improve the working environment in the engine compartment to a certain extent, improve the overall heat dissipation effect, and ensure that the engine can maintain a good operating state under various working conditions.

[0035] like Figure 5 and Figure 6 As shown, a guide frame 6 is also included. The guide frame 6 is connected between the inner wall of the heat insulation cover 1 and the inner wall of the shielding frame 51. The overall structure of the guide frame 6 is V-shaped. When the gas floats upward, it will be guided by the structure of the guide cover. After the gas moves up and contacts the sound insulation cotton 3, it will float around, and then be guided to the air outlet through the structure above the guide cover for discharge. The space between the guide frame 6 and the shielding frame 51 constitutes a drainage chamber.

[0036] like Figure 7-Figure 9 As shown, a drainage mechanism is also included, which includes an arc-shaped guide pipe 71, a drain pipe 72 and a connecting pipe 73. The right side of the guide frame 6 is connected to the arc-shaped guide pipe 71, and the arc-shaped guide pipe 71 is reciprocatingly bent and arranged in the heat insulation cover 1 and located below the cooling pipe 41, so that the liquid attached to the cooling pipe 41 will drip into the arc-shaped guide pipe 71. A plurality of connecting pipes 73 are evenly spaced and connected to the left side of the arc-shaped guide pipe 71. The connecting pipe 73 passes through the guide frame 6 and extends into the drainage chamber. The arc-shaped guide pipe 71 is inclined with the left side lower and the right side higher. The left side of the shielding frame 51 is connected to the drain pipe 72, and one end of the drain pipe 72 extends into the drainage chamber so that the water in the drainage chamber can be discharged through the drain pipe 72.

[0037] When the hot air is cooled through the cooling pipe 41, the moisture mixed in the hot air will adhere to the surface of the cooling pipe 41 due to the temperature drop and gradually condense into water droplets. These condensed water droplets will slide along the surface of the cooling pipe 41 and finally drip onto the arc-shaped guide pipe 71 below. The design of the arc-shaped guide pipe 71 can effectively collect these condensed water and guide the water into the drain chamber through the connecting pipe 73. The drain chamber then discharges the collected condensed water through the drain pipe 72. This design can not only effectively treat the condensed water and prevent it from accumulating in the cooling pipe 41, but also protect the engine and its surrounding components from water erosion, thereby extending their service life.

[0038] like Figure 10 and Figure 11 As shown, guide cotton 8 is also included. A layer of guide cotton 8 is connected to the bottom of the cooling tube 41, and the bottom of the guide cotton 8 is connected to the arc-shaped guide tube 71. The guide cotton 8 can effectively guide the condensed water attached to the cooling tube 41 to flow into the arc-shaped guide tube 71 through the guide cotton 8.

[0039] like Figure 12 As shown, a filter screen 9 is also included. The bottom of the shielding frame 51 is connected to the filter screen 9. The filter screen 9 is used to effectively filter impurities in the engine compartment of the automobile. By setting the filter screen 9, dust, debris and other impurities can be blocked from entering the interior of the heat shield 1, thereby protecting the heat shield 1 and its internal components from pollution and damage. This design not only keeps the interior of the heat shield 1 clean and extends its service life, but also ensures the efficient operation of the cooling system and avoids the reduction of heat dissipation effect due to clogging by impurities.
