Description

Technical Field

[0001] The present invention relates to the technical field of automotive parts, and particularly to a flow guiding structure for a cooling module with anti-backflow function and a cooling system. Background Art

[0002] The internal environment of the vehicle engine compartment is complex and the temperature in the compartment is relatively high. Special control and optimization are required for the overall vehicle thermal management performance. The cooling module (including the radiator of the engine cooling system and the air conditioner condenser), as an important part of the vehicle, is located at the front of the engine compartment. When working, it uses the air entering from the outside of the vehicle body through the front grille to cool and dissipate heat for itself, so as to achieve the effect of cooling the internal circulating water. Thermal balance is an important indicator of the cooling module. There are many factors affecting the thermal balance of the cooling system, and the hot air backflow in the engine compartment is a very important factor. To ensure good heat dissipation performance of the vehicle, it is necessary to avoid the hot air backflow in the engine compartment as much as possible. There is a large gap between the cooling module of traditional vehicles and the upper beam of the water tank, which easily causes the air with a higher temperature in the engine compartment to flow back above the cooling module through this gap, resulting in too high an inlet air temperature in front of the condenser, thus affecting the heat dissipation performance of the cooling module. Research has found that if the inlet air temperature of the cooling module remains high for a long time, it is easy to reduce the working efficiency of the cooling module, resulting in poor air-conditioning refrigeration effect, weak engine acceleration, and even serious consequences such as the air conditioner stopping running in high-temperature weather.

[0003] If there is hot air backflow in the engine compartment, it will increase the burden on the cooling system. Therefore, when there is basically no surplus in the cooling capacity of the cooling system, it is very necessary to install a windshield assembly to isolate the hot air in the engine compartment from the front end of the radiator and intercooler assembly. For a vehicle, within the limited space of its engine compartment, the windshield assembly not only needs to form good sealing with the cab components to effectively prevent hot air backflow, but also needs to avoid interference with the transmission shift flexible shaft and the intercooler.

[0004] Compared with passenger cars, the thermal management of the engine compartment of trucks has not been regarded as a major design hard point in the early vehicle product design. Therefore, it is impossible to better control the entry of low-temperature air in front of the cooling module, resulting in limited air-blocking effect and inability to prevent the hot air backflow behind the cooling module, leading to low cooling efficiency, overheating risk of the engine, and affecting the temperature of the overall vehicle use environment and fuel economy.

[0027] In order to make the technical problems solved by the present invention, the technical solutions adopted and the achieved technical effects clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0028] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over", and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "beneath", and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0030] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific embodiments.

[0031] As Figure 1 shown, this embodiment provides a backflow-preventing cooling module diversion structure, which is installed on the intercooler assembly and includes a top diversion plate 100, a first side diversion plate 200, and a second side diversion plate 300; the top diversion plate 100 is connected to the top surface of the intercooler assembly and includes a first bearing plate 111 and a plurality of first diversion fins 120, and the plurality of first diversion fins 120 are arranged at intervals on the upper plate surface of the first bearing plate 111; the first side diversion plate 200, the first side diversion plate 200 includes a first connection portion 220 connected to the right side of the intercooler assembly and a first diversion portion 210 connected to the first connection portion 220, and the first diversion portion 210 extends toward the front of the intercooler assembly and gradually moves away from the intercooler assembly; the second side diversion plate 300, the second side diversion plate 300 includes a second connection portion 320 connected to the left side of the intercooler assembly and a second diversion portion 310 connected to the second connection portion 320, and the second diversion portion 310 extends toward the front of the intercooler assembly and gradually moves away from the intercooler assembly.

[0032] The diversion structure of the anti-backflow cooling module can effectively reduce the high-temperature air flowing back from the rear of the intercooler assembly under the condition of the vehicle running at low speed and high load through the structural design of connecting the top diversion plate 100, the first side diversion plate 200 and the second side diversion plate 300 to the top surface, the right side and the left side of the intercooler assembly respectively. At the same time, it can also increase the flow rate of the low-temperature air from the front of the intercooler assembly, greatly improve the allowable ambient temperature of the thermal balance, reduce the intake air temperature of the engine, thereby improving the environmental adaptability and fuel economy of the whole vehicle. Under the condition of the vehicle running at high speed, this structure increases the flow rate of the free incoming low-temperature cooling air in front of the intercooler assembly, reduces the fan speed, and can also reduce the wind resistance of the whole vehicle, thus improving the fuel economy of the whole vehicle. The design of arranging a plurality of first diversion fins 120 at intervals on the first bearing plate 111 improves the diversion effect of the top diversion plate 100 on the air located above the intercooler. Combining the above improvements, the device realizes the diversion of the air-cooled cooling module and the optimization of the anti-backflow design. At the same time, the above structure also has the advantages of simple reliability and convenient manufacturing, and can be widely applied to the actual production of the cooling module of vehicles.

[0033] In this embodiment, the left-right direction of the intercooler assembly is perpendicular to the plane where the first diversion fins 120 are located, and a plurality of first diversion fins 120 are arranged along the left-right direction of the intercooler assembly. The position and structural design of the first diversion fins 120 ensure the diversion ability of the first diversion fins 120 for the air located above the intercooler assembly, so that the air can flow along a predetermined trajectory. The above improvement not only optimizes the structure of the first diversion fins 120, but also reduces the production cost of the top diversion plate 100 and the occupied space of the top diversion plate 100.

[0034] Furthermore, the top diversion plate 100 further includes a lifting diversion unit. The lifting diversion unit includes a second bearing plate 112. The lower plate surface of the first bearing plate 111 is attached to the top surface of the intercooler assembly, and the lifting diversion unit is arranged above the first bearing plate 111. The first diversion fins 120 are used to guide the air entering between the first bearing plate 111 and the second bearing plate 112 to the intercooler assembly, and the lifting diversion unit is used to guide the air located above the second bearing plate 112 to the upper rear of the intercooler assembly. The arrangement of the lifting diversion unit and the first bearing plate 111 attached to the top surface of the intercooler assembly enables the top diversion plate 100 to divert the air located above the intercooler assembly, so that a part of the air can cool the top surface of the intercooler assembly, and the other part of the air can be diverted to the upper rear by the lifting diversion unit to cool other components on the cooling module. The above design has a simple structure and good cooling effect, and effectively realizes the purpose of using the air above the intercooler assembly to cool the cooling module.

[0035] In this embodiment, the lifting and guiding unit further includes a plurality of second guiding fins 130, and the plurality of second guiding fins 130 are arranged at intervals on the upper plate surface of the second bearing plate 112. The design of arranging the plurality of second guiding fins 130 at intervals on the second bearing plate 112 improves the guiding effect of the top guiding plate 100 on the air above the intercooler.

[0036] Furthermore, the left-right direction of the intercooler assembly is perpendicular to the plane where the second guiding fins 130 are located, and the plurality of second guiding fins 130 are arranged along the left-right direction of the intercooler assembly. The above position and structural design of the second guiding fins 130 ensure the guiding ability of the second guiding fins 130 for the air diverted to the lifting and guiding unit, enabling the air to flow along a predetermined trajectory. The above improvement not only optimizes the structure of the second guiding fins 130 but also reduces the production cost and further reduces the occupied space of the top guiding plate 100.

[0037] In this embodiment, the second bearing plate 112 is located at the rear upper part of the first bearing plate 111, and the first bearing plate 111 is fixedly connected and integrally formed with the second bearing plate 112.

[0038] Preferably, the top surface of the intercooler assembly is provided with two first top holes and two second top holes. Two first top surface connection holes are opened in the middle of the second bearing plate 112, and two second top surface connection holes are opened at the edge of the second bearing plate 112. The first bolt 141 can pass through the first top surface connection hole and the first top hole and be screwed with the first nut 142. The second bolt 151 can pass through the second top surface connection hole and the second top hole and be screwed with the second nut 152.

[0039] Specifically, a first flanging is further provided behind the second guiding fin 130, and the plane where the first flanging is located is perpendicular to the front-rear direction of the intercooler assembly. The setting of the first flanging can lift the air passing through the gap between two adjacent second guiding fins 130 upward. The above structural improvement optimizes the anti-backflow cooling module guiding structure's operation of using air to cool other components located behind and above the cooling module.

[0040] Preferably, the anti-backflow cooling module guiding structure further includes a bottom guiding plate 400. The bottom guiding plate 400 includes a bottom surface connecting portion 410 connected to the bottom surface of the intercooler assembly and a third guiding portion 430 connected to the bottom surface connecting portion 410. The third guiding portion 430 extends toward the top surface of the intercooler assembly and gradually moves away from the intercooler assembly. The design of the bottom guiding plate 400 realizes the guiding of the air at the front bottom end of the intercooler assembly. The above improvement not only increases the air flow guiding to the lower part of the intercooler assembly but also can reduce the wind resistance of the anti-backflow cooling module guiding structure and the intercooler assembly, thereby further improving the fuel economy of the whole vehicle.

[0041] Preferably, two bottom holes are provided on the bottom surface of the intercooler assembly, and two bottom connection holes are formed on the bottom connection part 410. The bottom connection bolt 441 can pass through the bottom connection hole and the bottom hole and be screwed with the bottom connection nut 442.

[0042] Specifically, the bottom guide plate 400 further includes two side positioning parts 420. The two side positioning parts 420 are respectively attached to the left side and the right side of the intercooler assembly, and the two side positioning parts 420 are respectively fixedly connected to both ends of the bottom connection part 410 and respectively fixedly connected to both ends of the third guide part 430. The setting of the side positioning part 420 improves the positioning effect of the bottom guide plate 400 on the intercooler assembly and reduces the risk of the bottom guide plate 400 shifting in position.

[0043] In this embodiment, the material of the first guide part 210 is plastic or rubber; the material of the second guide part 310 is plastic or rubber. The first guide part 210 and the second guide part 310 made of rubber material both have good sealing performance, low production cost, stable structure and reliable operation. Specifically, the materials of the first connection part 220 and the second connection part 320 are both metal. Through the cooperative setting of the metal connection parts, the risk of collapse caused by the softening of the guide parts made of plastic or rubber material due to heat at high temperature can be reduced.

[0044] Preferably, both the first connection part 220 and the second connection part 320 are screwed to the intercooler assembly. Specifically, a first connection hole is provided on the first connection part 220, and the fourth bolt 230 passes through the first connection hole and is screwed to the right side of the intercooler assembly; a second connection hole is provided on the second connection part 320, and the fifth bolt 330 passes through the second connection hole and is screwed to the left side of the intercooler assembly.

[0045] The anti-backflow cooling module guide structure provided in this embodiment is verified to be effective through CFD calculation and support analysis. The anti-backflow effect under the low-speed climbing condition and the guide effect of the low-temperature cooling natural incoming flow under the high-speed condition have been significantly improved. Under the condition of the vehicle running at low speed and high load, the allowable ambient temperature of the thermal balance of the cooling module applying the anti-backflow cooling module guide structure provided in this embodiment can be increased by up to 4.60 °C at most, and the engine intake temperature is reduced by 5.70 °C; under the condition of the vehicle running at high speed, the flow rate of the low-temperature cooling air freely incoming in front of the cooling module applying the anti-backflow cooling module guide structure provided in this embodiment increases by about 83.24%, and the wind resistance of the vehicle is reduced by 0.006 - 0.010.

[0046] As Figure 2As shown, this embodiment also provides another anti-backflow cooling module diversion structure, which is different from the above anti-backflow cooling module diversion structure in that the first carrier plate 111 extends towards the front of the intercooler assembly and gradually moves away from the intercooler assembly. The first carrier plate 111 is used to direct the air entering between the first carrier plate 111 and the top surface of the intercooler assembly towards the intercooler assembly. The above design can divert the air located above the intercooler assembly, so that the air entering between the first carrier plate 111 and the top surface of the intercooler assembly can cool the top surface of the intercooler assembly, while the air located above the first carrier plate 111 can be diverted to the upper rear by the lifting diversion unit to cool other components on the cooling module. The above design also achieves the purpose of diverting the air located above the intercooler and cooling the cooling module, with a simple structure and reliable operation.

[0047] Specifically, a second flanging 160 is further provided behind the first diversion fin 120. The plane where the second flanging 160 is located is perpendicular to the front-rear direction of the intercooler assembly. The setting of the second flanging 160 can lift the air passing through the gap between two adjacent first diversion fins 120 upwards. The above structural improvement optimizes the operation of using air to cool other components located at the upper rear of the cooling module in this anti-backflow cooling module diversion structure.

[0048] Preferably, two top holes are provided on the top surface of the intercooler assembly. Two ear plates 170 protrude from the first carrier plate 111. Ear plate holes are provided on the ear plates 170. The third bolt 181 can pass through the ear plate holes and the top holes and be screwed with the third nut 182.

[0049] In the actual application of this embodiment, the lengths of the first side deflector 200 and the second side deflector 300 in the up-down direction of the intercooler assembly can be adjusted adaptively. The above design can reduce the production cost and the occupied space of the first side deflector 200 and the second side deflector 300 on the premise of ensuring a certain degree of anti-backflow and diversion ability of this anti-backflow cooling module diversion structure.

[0050] This embodiment also provides a cooling system, including a cooling module, a grille, and the above anti-backflow cooling module diversion structure. The cooling module includes a radiator assembly and an intercooler assembly. The radiator assembly is located behind the intercooler assembly, and the grille fits against the front of the intercooler assembly.

[0051] In this cooling system, the setting that the middle grille fits the intercooler assembly avoids the backflow of air between the middle grille and the intercooler assembly, greatly improving the cooling effect of the air on the front of the intercooler assembly. The radiator assembly is located behind the intercooler assembly. This setting can not only ensure that the temperature change of the intercooler assembly can be timely feedback to the radiator assembly, but also enable the air from the front to continue to cool the radiator assembly. The above design improves the efficiency of air cooling, optimizes the structure of the cooling system, and reduces the occupied space.

[0052] The volume of the radiator assembly is relatively large. Therefore, the air guided by the top deflector 100 to the upper rear of the intercooler assembly will directly guide to the front of the radiator assembly, thus achieving the purpose of cooling the front of the radiator assembly.

[0053] Preferably, the first carrier plate 111, the first deflector 210 and the second deflector 310 are all in contact with the middle grille respectively. The above design eliminates the gap between the anti-backflow cooling module deflector structure and the middle grille, avoiding the disorder of the air flow through the middle grille due to the existence of the above gap, ensuring the accurate diversion of the air by the first carrier plate 111, the first deflector 210 and the second deflector 310, and enabling the air flowing into this cooling system to flow smoothly along the predetermined trajectory, greatly ensuring the stability of the operation of this cooling system.

[0054] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
