The engine cooling system has the function of timely dissipating partial heat absorbed by heated parts in the engine, so that the engine can be properly cooled, and the engine can be ensured to work in an optimum temperature range. The traditional engine cooling system comprises a radiator, a water pump, a fan and a fan cover, wherein the water pump circulates cooling water from an engine to the radiator, and natural wind with a certain speed is supplied by the fan and blows over the radiator to dissipate the heat of the cooling water in the radiator. As can be seen from the above, the heat dissipation effect of the heat sink is related to the amount of the blown natural wind, and the more the blown natural wind, the better the cooling effect of the heat sink. In order to ensure that enough natural wind is sucked by the fan to pass through the radiator, a wind protection cover can be arranged between the fan and the radiator to guide the natural wind supplied by the fan through the wind protection cover, so that the natural wind blown out by the fan can completely pass through the radiator, and a better radiating effect is achieved.
Specifically, referring to fig. 1, fig. 1 is a schematic structural diagram of a conventional wind cowl, which includes a first cover 10, a transition ring 20, and a second cover 30. The first cover 10 covers the heat sink, the transition ring 20 is used to connect the first cover 10 and the second cover 30, and the second cover 30 covers the fan. Connect first cover body 10 and second cover body 30 through transition ring 20 for first cover body 10 and second cover body 30 can form wind-guiding passageway 40, and the both ends of wind-guiding passageway 40 are provided with fan and radiator respectively, and the natural wind that the fan blew off just can be all through the radiator through wind-guiding passageway 40, thereby improves the radiating effect of radiator, guarantees the cooling effect of radiator to the cooling water. However, because the first cover 10 and the second cover 30 are close to the radiator and the fan, vibration generated by the radiator and the fan in the using process can be transmitted to the first cover 10 and the second cover 30, so that the transition ring 20 located between the first cover 10 and the second cover 30 is affected by vibration to generate looseness, and the transition ring 20 generates a certain suction force when the fan rotates, so that when the transition ring 20 is loosened to a certain degree, the transition ring 20 is affected by the suction force of the fan to cause the transition ring 20 to fall off from the wind shield, and the fallen transition ring collides with the fan, thereby causing damage to the engine cooling system.
To this end, referring to fig. 2 to 5, an embodiment of the present invention provides a wind guard, which includes a first cover 10, a transition ring 20, and a second cover 30 connected in sequence in a first direction. First cover 10 is connected to a radiator, second cover 30 is connected to an engine, and transition ring 20 connects first cover 10 to second cover 30. Specifically, the first cover 10, the transition ring 20 and the second cover 30 define an air guiding channel 40 extending in the first direction and penetrating therethrough, and the fan is installed in the air guiding channel 40. When the engine is in operation, natural wind flows through the radiator under the action of suction force of the fan and flows out through the wind guide channel 40, so that the temperature of cooling water flowing through the radiator is reduced, and the purpose of cooling the engine is achieved.
In an embodiment, the first cover 10 is provided with a first air guiding hole 11 penetrating along a first direction, and the first air guiding hole 11 faces the heat dissipating blade of the heat sink. Second cover 30 has second air guiding hole 31 penetrating in the first direction, and the fan is installed in second air guiding hole 31. The first air guiding hole 11, the transition ring 20 and the second air guiding hole 31 can form an air guiding passage 40 which flows in the first direction between the fan and the radiator.
The transition ring 20 includes a first mounting portion 21, a vibration damping portion 22, and a second mounting portion 23, the first mounting portion 21 is connected to the first cover 10 along a circumferential direction of the first air guiding hole 11, the second mounting portion 23 is connected to the second cover 30 along a circumferential direction of the second air guiding hole 31, the vibration damping portion 22 is disposed between the first mounting portion 21 and the second mounting portion 23, and at least a portion of the vibration damping portion 22 passes through the first mounting portion and meanders in a second direction intersecting the first direction to damp vibration.
When the engine cooling system is in operation, the vibration of the fan and the radiator is transmitted to the transition ring 20 through the first mounting portion 21 and the second mounting portion 23, both ends of the vibration damping portion 22 are fixedly mounted since both the first mounting portion 21 and the second mounting portion 23 are fixedly mounted, and when the vibration is transmitted to the transition ring 20, the vibration is concentrated on the zigzag extending portion of the vibration damping portion 22 to be compressed by the zigzag extending portion of the vibration damping portion 22 to absorb the vibration since both ends of the vibration damping portion 22 are fixedly mounted.
Specifically, when the heat sink generates vibration, the first cover 10 drives the first mounting portion 21 to vibrate together, and when the transition ring 20 transmits the vibration damping portion 22, the vibration is elastically deformed and compressed at the portion extending in a zigzag manner of the vibration damping portion 22, so that the vibration is not further transmitted to the second mounting portion 23, and the second mounting portion 23 does not move relative to the second cover 30, thereby preventing the second mounting portion 23 from falling off from the second cover 23.
Further, when the fan generates vibration, the second cover 30 drives the second mounting portion 23 to vibrate together, and when the transition ring 20 transmits the vibration damping portion 22, the vibration will generate elastic deformation at the portion extending in a zigzag manner of the vibration damping portion 22 and then be compressed, so that the vibration will not be further transmitted to the first mounting portion 21, and the first mounting portion 21 will not move relative to the first cover 10, thereby preventing the first mounting portion 21 from falling off from the first cover 10.
Therefore, the vibration transmitted to the transition ring 20 by the fan and the radiator is absorbed by the vibration absorption portion 22, so that the vibration does not act on the first mounting portion 21 and the second mounting portion 23, the first mounting portion 21 is prevented from falling off from the first cover body 10, the second mounting portion 23 falls off from the second cover body 30, the problem that the transition ring 20 is loosened due to vibration is avoided, and the transition ring 20 is prevented from falling off from the fan cover and being sucked by the fan, so that the fan is prevented from being damaged.
In the cowl, the vibration damping portion 22 is attached to the transition ring 20, and the vibration generated during the operation of the engine and the radiator is absorbed by the vibration damping portion 22, thereby preventing the transition ring 20 from falling off from the first cover 10 and the second cover 30. Compared with the prior art, the wind shield ensures that enough natural wind is sucked by the fan to blow through the radiator, and simultaneously improves the installation strength of the wind shield through the vibration reduction part 22, so that the whole engine cooling system has stronger reliability and is not easy to damage.
Specifically, in the embodiment of fig. 2, the first direction is a left-right direction, and the second direction described below is an up-down direction.
In the embodiment of the present invention, the first mounting portion 21, the vibration attenuating portion 22, and the second mounting portion 23 of the transition ring 20 are integrally formed, and at least a portion of the vibration attenuating portion 22 is corrugated in the second direction. When the vibration damping portion 22 is corrugated, the vibration damping portion 22 may have more deformation in the second direction, that is, the corrugated vibration damping portion 22 may be used to eliminate vibration with larger amplitude and frequency, such as vibration generated during driving of a vehicle, so as to further avoid the problem that the transition ring 20 is affected by vibration to cause looseness, and prevent the transition ring 20 from falling off from the cowl to be sucked by the fan, which may cause damage to the fan.
In the embodiment, the second cover 30 has a limiting portion 32 protruding toward the transition ring 20, and one side of the damping portion 22 in the first direction abuts against the limiting portion 32. Since the vibration damping portion 22 extends in a zigzag manner, the vibration damping portion 22 itself has a certain elastic force, and the elastic force can eliminate the vibration of the transition ring 20 in the second direction, and can also generate deformation by being pressed against the limiting portion 32, so as to eliminate the vibration of the transition ring 20 in the first direction. Therefore, the vibration of the transition ring 20 in the first direction and the second direction can be eliminated through the vibration damping part 22, the vibration of the first mounting part 21 and the second mounting part 23 when the engine cooling system works is greatly reduced, and the connection strength of the transition ring 20 and the first mounting part 21 and the second mounting part 23 is ensured.
In the embodiment of the present invention, the first cover 10 is provided with a first engaging groove 12 circumferentially arranged along the first air guiding hole 11, and the first mounting portion 21 is embedded in the first engaging groove 12.

Furthermore, the transition ring 20 further includes a third mounting portion 24, the third mounting portion 24 and the first mounting portion 21 are arranged at an interval in the first direction, and a gap between the first mounting portion 21 and the third mounting portion 24 forms a second engaging groove 25. When the first mounting portion 21 is mounted in the first card slot 12, one of the first card portion 14 and the second card portion 15, which is close to the second card portion 15, is embedded in the second card slot 25. Therefore, the first locking groove 12 and the second locking groove 25 are matched with each other, so that the first cover 10 and the transition ring 20 are more tightly mounted, and the transition ring 20 is less prone to falling off from the first cover 10.
In particular, in the embodiment, one of the first mounting portion 21 and the third mounting portion 24 has a positioning portion, and one of the first clamping portion 14 and the second clamping portion 15 located in the second clamping groove 25 has a matching portion, and the positioning portion and the matching portion are in positioning matching with each other. Specifically, one of the matching portion and the positioning portion is a matching groove 26, and the other is a positioning protrusion 13, so that the transition ring 20 and the first cover 10 can be limited and fixed by mutually matching the positioning portion and the matching portion, and relative movement between the transition ring 20 and the first cover 10 is avoided, so that the installation strength of the transition ring 20 and the first cover 10 is further improved, and the transition ring 20 is prevented from falling off from the first cover 10.
