[0041] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0042] Please refer to the appendixFigures 1-8 , embodiments of the present application provide an arrangement structure of a cooling system, which is applicable to a hybrid vehicle with a hybrid power system. The cooling system includes a coolant tank 6, a front bulkhead cross member 1 for separating the front engine compartment and the cockpit, and a lower windshield cross member 2 for fixing the front windshield. Among them, the coolant tank 6 has a first liquid chamber and a second liquid chamber which are separated. The engine cooling pipeline is connected to the first liquid chamber, and the battery cooling pipeline is connected to the second liquid chamber. By integrally arranging the coolant tank 6, coolant can be supplied to both the oil drive system where the engine is located and the electric drive system where the battery and the drive motor are located, which can avoid dispersedly arranging two tanks on the vehicle body, not only facilitating the layout but also reducing the space occupation.

[0043] The coolant tank 6 is arranged on the front bulkhead cross member 1 and fixed between the front bulkhead cross member 1 and the lower windshield cross member 2. It can be directly connected to and fixed by the front bulkhead cross member 1 and the lower windshield cross member 2, and the front bulkhead cross member 1 and the lower windshield cross member 2 can enhance the stability of the coolant tank 6 by having a clamping or surrounding effect, so that the coolant tank 6 can be stably fixed on the vehicle body without a bracket, further eliminating the installation of the bracket and the space occupied by the bracket, simplifying the structure and reducing the space occupation requirements. At the same time, since the coolant tank 6 is located between the engine and the battery in the vehicle body length direction, the engine cooling pipeline can be extended forward to reach the engine, and the battery cooling pipeline can be extended backward to reach the battery without being overly bent. For example, in the present application, the engine cooling pipeline is laid forward along the longitudinal beam 8 to reach the engine, such as being connected to the radiator of the engine, and the battery cooling pipeline is laid backward directly along the vehicle body floor (the bottom space under the cockpit) after passing through or bypassing the front bulkhead cross member 1 and is connected to the heat dissipation component of the battery pack; the laying of the cooling pipeline is simple, and the pipeline length is short, which can shorten the cooling path and improve the cooling efficiency and cooling effect.

[0044] It can be seen that the layout structure of the cooling system provided by this application integrates the essential coolant tank 6 in the engine cooling system and the battery cooling system, without the need to disperse the arrangement of two liquid tanks. Moreover, the integrated coolant tank 6 is arranged between the engine and the battery. The cooling pipelines connected thereto can reach the engine when extending forward and can extend to the battery when extending backward, simplifying and shortening the two sets of cooling pipelines leading to the engine and the battery respectively. This not only reduces the space layout requirements of the cooling system and improves its layout convenience on the vehicle body, but also reduces the actual occupied space and can provide space for other vehicle body components, thereby improving the layout convenience of the overall vehicle body structure. At the same time, the cooling path is effectively shortened and the cooling efficiency is improved. Meanwhile, the integrated coolant tank 6 is specifically arranged in the narrow space between the front bulkhead beam 1 and the lower cross beam 2 of the front windshield. On the one hand, the installation bracket can be saved. The coolant tank 6 is directly connected to and fixed by the two cross beams, and its stability can be enhanced by the clamping of the two cross beams. On the other hand, it occupies the rear space with low utilization rate in the front engine compartment and will not affect the layout of other important components such as the engine in the front engine compartment, improving the space utilization rate of the front engine compartment.

[0045] Specifically, the coolant tank 6 includes a top cover 66 and a bottom cover 67 that are buckled together. The top cover 66 and the bottom cover 67 are buckled and connected to enclose the coolant tank 6. The coolant tank 6 can be in the shape of a flat cuboid, that is, the height of the tank body is less than the length and width. The coolant tank 6 includes a top plate, a bottom plate, and four side plates. There is also a partition 60 inside the tank. Among them, the top plate is located on the top cover 66, the bottom plate is located on the bottom cover 67, and the partition 60 and the four side plates each have an upper half on the top cover 66 and a lower half on the bottom cover 67. After the top cover 66 and the bottom cover 67 are buckled, a complete partition 60 and four side plates are formed, and a complete coolant tank 6 is also composed.

[0046] The partition 60 divides the tank cavity into a first liquid cavity and a second liquid cavity. The first liquid cavity is provided with a first liquid outlet 601 and a first liquid return port 603, and the second liquid cavity is provided with a second liquid outlet 602 and a second liquid return port 604. The battery cooling pipeline includes a battery inlet pipe 41 and a battery return pipe 42. The battery inlet pipe 41 is connected to the first inlet port to supply coolant to the heat dissipation components of the battery (such as the heat dissipation plate in the battery pack). The battery return pipe 42 is connected to the first liquid return port 603 to make the coolant flow back to the coolant tank 6. The engine cooling pipeline includes an engine inlet pipe 51 and an engine return pipe 52. The engine inlet pipe 51 is connected to the second inlet port to supply coolant to the radiator of the engine. The engine return pipe 52 is connected to the second liquid return port 604 to make the coolant flow back to the coolant tank 6.

[0047] Such as Figure 2 and Figure 4As shown in the figure, an anti-torsion beam 3 is provided on the top end surface of the front bulkhead beam 1. The anti-torsion beam 3 (also known as the anti-twist beam or torsion beam) connects the left and right wheel arches 7, enabling the vehicle body to remain stable when turning or under lateral force and reducing vehicle body roll. In the automotive suspension system, compared with independent suspensions, vehicles with torsion beam suspensions can save more interior space because their design is more compact; torsion beam suspensions are generally simpler and lighter than independent suspensions.

[0048] The coolant reservoir 6 is arranged on the anti-torsion beam 3 and is positioned and inserted into the anti-torsion beam 3 through a plug-in structure at the bottom. With such an arrangement, the coolant reservoir 6 can be stably supported by the anti-torsion beam 3, and can be conveniently positioned and installed through the plug-in structure, ensuring installation accuracy.

[0049] Specifically, the anti-torsion beam 3 includes a main beam 31 laid on the top end surface of the front bulkhead beam 1 and auxiliary beams 32 located at both ends of the main beam 31. Both ends of the main beam 31 are respectively connected to two wheel arches 7 on the vehicle body. The auxiliary beams 32 are inclined or erected, with one end connected to the main beam 31 and the other end connected to the lower front windshield crossbeam 2. The coolant reservoir 6 is placed and connected on the main beam 31 and is located between the two auxiliary beams 32.

[0050] The plug-in structure includes a plug-in protrusion provided on the coolant reservoir 6 and a plug-in groove provided on the anti-torsion beam 3. A shock-absorbing sleeve or shock-absorbing pad is also provided in the plug-in groove, for example, a shock-absorbing sleeve for sleeving on the plug-in protrusion is provided. The plug-in protrusion can specifically be a plug-in post. By arranging the plug-in protrusion on the coolant reservoir 6 and the plug-in groove on the anti-torsion beam 3, it can be avoided that the connection is unstable due to the shallowness of the plug-in groove.

[0051] As Figure 2 and Figure 5 shown in the figure, the lower front windshield crossbeam 2 includes a crossbeam body 21 and a water diversion plate 22 provided on the side of the crossbeam body 21 facing the vehicle head. The water diversion plate 22 forms a water diversion groove for receiving liquids such as rainwater flowing down from the front windshield and guiding the liquids to the discharge location. Specifically, a lug 61 protrudes from the top or side of the coolant reservoir 6, and the lug 61 is connected to the water diversion plate 22. With such an arrangement, the coolant reservoir 6 can be stably connected to the water diversion plate 22 directly through the lug 61 and bolts, without the need for a mounting bracket, with a simple structure, which is convenient for layout and saves space.

[0052] Furthermore, a positioning groove 201 that is recessed towards the cockpit direction is provided at the edge of the water diversion plate 22 for the coolant reservoir 6 to be embedded, and the lug 61 is provided on the side plate of the coolant reservoir 6 facing the cockpit. The height of the coolant reservoir 6 can exceed the water diversion plate 22, occupying some unused space between the water diversion plate 22 and the engine hood to increase the overall volume of the coolant reservoir 6. The lug 61 and the water diversion plate 22 can be flatly and fittingly connected.

[0053] Since there is a temperature difference between the coolant temperature required by the engine and the coolant temperature required by the battery, and the temperature of the coolant used by the engine is higher than that of the coolant used by the battery, in the related art where the cooling systems of the engine and the battery are separately arranged, there is a temperature difference between the coolant temperature used by the engine and the coolant temperature used by the battery.

[0054] Therefore, in the embodiments of the present application, as Figure 7 shown, at least two partitions 60 are provided on the partition plate 60 in the coolant tank 6. The at least two partitions 60 are spaced apart, and the intervals between the at least two partitions 60 form an isolation chamber 607 that separates the first liquid chamber and the second liquid chamber. In this way, the inside of the isolation chamber 607 is an air environment, which can play a heat insulation effect, can better ensure the different temperatures of the coolant in the two liquid chambers, and can enable the engine coolant and the battery coolant to use coolants with different temperature values and the two coolants will not generate temperature interference.

[0055] The first liquid chamber and the second liquid chamber are arranged along the vehicle body width direction. In this way, it can better adapt to the space at the installation position and can better increase the volume of the coolant tank 6.

[0056] A first liquid outlet 601 and a second liquid outlet 602 are provided on the first side plate 63 of the first liquid chamber away from the second liquid chamber. The first liquid outlet 601 is connected to the battery inlet pipe 41 of the battery cooling pipeline, and the second liquid outlet 602 is connected to the engine inlet pipe 51 in the engine cooling pipeline. That is, the liquid outlets of the two liquid chambers are opened on the same side plate of the coolant tank 6. In this way, the engine cooling pipeline and the battery cooling pipeline can be centrally laid out, which is convenient for fixing and also avoids the mess of pipelines in the front engine compartment from affecting the layout and maintenance of other components.

[0057] A first liquid guide pipe 68 connected to the first liquid outlet 601 and extending towards the middle of the first liquid chamber is provided in the first liquid chamber. In this way, the coolant in the first liquid chamber can flow into the first liquid guide pipe 68 from the middle area of the first liquid chamber, which can accelerate the flow rate and supply of the coolant.

[0058] A second liquid guide pipe 69 connecting the second liquid outlet 602 and the second liquid chamber is also provided in the coolant tank 6. That is, the second liquid guide pipe 69 passes through the first liquid chamber and is connected to the second liquid outlet 602. The end of the second liquid guide pipe 69 in the second liquid chamber can also be arranged in the middle area of the second liquid chamber to improve the flow rate and supply of the coolant in the second liquid chamber.

[0059] In some embodiments, a diverter 9 is connected in the battery cooling pipeline. The diverter 9 is arranged outside the longitudinal beam 8 near the first side plate 63 and near the liquid outlet, which is beneficial to shortening the cooling pipeline. It can also make the pipe section of the battery liquid inlet pipe 41 between the diverter 9 and the coolant kettle 6 and the engine liquid inlet pipe 51 be laid along the same longitudinal beam 8 near the first side plate 63 on the same side of the coolant kettle 6. With such an arrangement, the pipelines can be set more centrally, reducing the complexity of layout and also reducing the required layout space, thereby improving the space utilization rate of the engine compartment.

[0060] Specifically, the battery liquid inlet pipe 41 includes a first liquid pipe 411 connecting the first liquid outlet 601 and the diverter 9, and a second liquid pipe 412 connecting the diverter 9 and the heat dissipation component. The first liquid pipe 411, the engine liquid inlet pipe 51, and the local pipe section of the second liquid pipe 412 near the diverter 9 are all laid along the same longitudinal beam 8 near the first side plate 63.

[0061] With such an arrangement, the local pipe sections of the first liquid pipe 411 and the second liquid pipe 412 in the battery cooling pipeline near the diverter 9, and the engine liquid inlet pipe 51 are all laid along the same longitudinal beam 8, and it is the longitudinal beam 8 near the two liquid outlets, which can significantly shorten the pipeline length and simplify the pipeline laying structure.

[0062] The second liquid pipe 412 includes a first section laid along the length direction of the front bulkhead crossbeam 1, a second section laid along the height direction of the front bulkhead crossbeam 1, and a third section laid backward from the front bulkhead crossbeam 1 along the vehicle body length direction. Pipe clamps are arranged on the front beam surface of the front bulkhead crossbeam 1 to fix the second liquid pipe 412. In this way, the second liquid pipe 412 is fixed by the front bulkhead crossbeam 1 and can be directly laid backward after bypassing the front bulkhead crossbeam 1 to reach the battery, with a short path and a simple laying structure.

[0063] For the liquid return port, the first liquid return port 603 of the first liquid cavity is arranged on the first side plate 63. The battery liquid return pipe 42 includes a long pipe section connecting the battery heat dissipation component and the diverter 9, and a first liquid return pipe connecting the diverter 9 and the first liquid return port 603. The first liquid return pipe can be arranged between the diverter 9 and the first side plate 63 of the coolant kettle 6 and can be located above the first liquid pipe 411 and the engine liquid inlet pipe 51 in the battery cooling pipeline.

[0064] The second liquid return port 604 of the second liquid cavity is arranged on the second side plate 64 connected to the first side plate 63 and facing the engine. A connecting pipe clamp 62 is also arranged on the second side plate 64. The tail section of the engine liquid return pipe 52 in the engine cooling pipeline is connected to the second liquid return port 604, and the tail section is laid along the length direction of the second side plate 64 and fixed at the second side plate 64 through the connecting pipe clamp 62.

[0065] Reinforcing rib plates are provided in both the first liquid chamber and the second liquid chamber. The reinforcing rib plates are arranged horizontally and vertically in multiple numbers to divide the liquid chamber into multiple sub-chambers, and liquid-permeating holes are formed in each sub-chamber. On the top cover 66 of the coolant kettle 6, liquid filling ports 606 corresponding to the first liquid chamber and the second liquid chamber respectively are provided. In the first liquid chamber and the second liquid chamber, the volume of the sub-chamber directly opposite to the liquid filling port 606 is larger than that of other sub-chambers to form an expansion chamber 605. The reinforcing rib plates enclosing the expansion chamber 605 include arc-shaped rib plates 65 and the remaining flat rib plates in a flat plate shape. Multiple liquid-permeating holes facing different directions are provided on the remaining flat rib plates. As Figure 7 shown, the remaining flat rib plates may specifically be three flat rib plates respectively located on both sides of the arc-shaped rib plate 65 and directly opposite to the arc-shaped rib plate 65, and liquid-permeating holes are formed in all three flat rib plates. The three liquid-permeating holes communicate with three different sub-chambers. With such a setting, on the basis of providing the reinforcing rib plates, the liquid inlet speed during liquid filling can be increased, and the three liquid-permeating holes are distributed beside and directly opposite to the arc-shaped rib plate 65, and the added liquid can flow quickly to the liquid-permeating holes under the guidance of the arc-shaped rib plate 65.

[0066] A positioning and docking structure may be provided between the top cover 66 and the bottom cover 67, for example, a docking groove is provided on one of them, and a docking protrusion inserted into the docking groove is provided on the other. Through the positioning and docking structure, the top cover 66 and the bottom cover 67 can be accurately docked and connected, enhancing the flatness and sealing performance of the connection part.

[0067] Specifically, the arc-shaped rib plate 65 includes an upper half plate located on the top cover 66 and a lower half plate located on the bottom cover 67, and the positioning and docking structure may be provided on the upper half plate and the lower half plate.
