In addition, although the examples described herein have various configurations, other configurations are possible as will be apparent after understanding the disclosure of the present application.

[0037] According to a first aspect of the utility model, a U-shaped flow radiator for a vehicle is provided, such as Figures 1 to 8 As shown, the vehicle U-shaped flow radiator is used in the cooling system of the vehicle and can be used for the circulation of antifreeze liquid. Since the circulation of antifreeze liquid is U-shaped, it is a U-shaped flow radiator. The vehicle U-shaped flow radiator includes a first water chamber 1, a second water chamber 2 and a cooling part.

[0038] In the following description, reference will be made to Figures 1 to 8 The detailed structures of the first water chamber 1, the second water chamber 2 and the cooling part of the U-shaped flow radiator for a vehicle are described in detail.

[0039] like Figure 1 and Figure 2 As shown, in the embodiment, the first water chamber 1 and the second water chamber 2 are respectively arranged at the two ends of the cooling part, the first water chamber 1 is used to receive and discharge the antifreeze, and the second water chamber 2 is used to assist the circulation of the antifreeze in the cooling part. The cooling part includes a first cooling pipe 3 and a second cooling pipe 4. A partition 101 is arranged in the middle of the first water chamber 1 so that the first water chamber 1 is divided into a first subsection 102 and a second subsection 103. The first subsection 102 is connected to the first cooling pipe 3, the second subsection 103 is connected to the second cooling pipe 4, and the second water chamber 2 is connected to the first cooling pipe 3 and the second cooling pipe 4. The process of the U-shaped flow circulation is as follows: the high-temperature and high-pressure antifreeze enters from the first subsection 102 of the first water chamber 1, and enters the first cooling pipe 3 of the cooling part, then enters the second water chamber 2, and enters the second cooling pipe 4 of the cooling part in the second water chamber 2, and then the low-temperature and low-pressure antifreeze enters the second subsection 103 of the first water chamber 1 and is discharged. The temperature difference of the antifreeze entering and exiting is more than 30°C.

[0040] like Figure 6 and Figure 7 As shown, in the embodiment, the first water chamber 1 and the second water chamber 2 are connected to the cooling part through the connecting assembly 5, and the connecting assembly 5 is passed through both ends of the cooling part. The height of the partition 101 is H, which is smaller than the height of the interior of the first water chamber 1, so as to ensure that a gap is provided between the partition 101 and the connecting assembly 5, so that part of the coolant in the first subsection 102 and part of the coolant in the second subsection 103 can contact each other. Since the partition 101 does not completely isolate the first section 102 and the second section 103, a gap is formed between the partition 101 and the connecting component 5, and the height of the gap is 0.5-1mm. A small amount of antifreeze liquid in the first section 102 and the second section 103 will flow, so that the alternation of hot and cold becomes mild, and the fatigue failure of the first cooling pipe 3 and the second cooling pipe 4 located in the middle is reduced; since a gap is set between the partition 101 and the connecting component 5, there is no clamping component (such as a rubber O-ring) at this place during assembly, and there is no clamping force at this place, and the press-fitting of the connecting component 5 and the first water chamber 1 will not crack in the middle, thereby increasing the service life of the radiator.

[0041] Preferably, as shown in Figure 2, in the embodiment, the first water chamber 1 includes a first shell 104, and a stepped connection portion 105 is formed at the end of the first shell 104 facing the cooling portion, and the first shell 104 is connected to the connection assembly 5 through the stepped connection portion 105. The stepped connection portion 105 is arranged at the outer edge of the first shell 104 and surrounds the outer edge. The outer side of the stepped connection portion 105 is raised relative to the inner side, and the outer side and the inner side refer to the outer side and the inner side of the first shell 104. The sealing member for pressing described below can be arranged on the stepped connection portion 105, and the stepped connection portion 105 is also the connection between the first shell 104 and the connection assembly 5.

[0042] Preferably, if Figures 2 to 5As shown, in the embodiment, the connection assembly 5 includes a connection member 501 and a sealing ring 502. The connection member 501 is provided with a plurality of through holes 505 for the first cooling pipe 3 and the second cooling pipe 4 to pass through. A stepped buckle portion 503 is formed on one side of the connection member 501 facing the first shell 104. The sealing ring 502 is arranged on the stepped buckle portion 503. The stepped buckle portion 503 is arranged corresponding to the stepped connection portion 105. The outer peripheral side of the side (for the sake of description, this side is referred to as the docking surface in the following) of the connection member 501 provided with the through hole 505 is provided with a stepped buckle portion 503. The outermost position of the docking surface is lower than the docking surface to form a step shape. The sealing ring 502 is arranged inside the step shape. The shape of the stepped connection portion 105 corresponds to the stepped buckle portion 503, so that the two can press the sealing ring 502 tightly to achieve press-fit sealing. The sealing ring 502 may be formed into an approximately rectangular ring structure. The sealing ring 502 is used for compression and sealing and may be made of materials such as rubber.

[0043] Preferably, if Figures 2 to 5 As shown, in the embodiment, an outer edge portion 108 is formed on the peripheral side of the first shell 104, and a pressing portion 504 is also provided on the peripheral side of the connecting member 501. When the first shell 104 is installed on the connecting member 501, the pressing portion 504 abuts against the outer edge portion 108 of the first shell 104, and the pressing portion 504 presses the outer edge portion 108 and makes the outer edge portion 108 located inside the pressing portion 504, thereby realizing the press-fitting of the first water chamber 1 and the connecting component 5.

[0044] Preferably, if Figures 2 to 5 As shown, in the embodiment, when the first housing 104 is installed on the connecting member 501, the sealing ring 502 is arranged between the stepped buckling portion 503 and the stepped connecting portion 105 for press-fit sealing.

[0045] Preferably, if Figure 2 As shown, in the embodiment, the first housing 104 further includes a water inlet 106 and a water outlet 107, the water inlet 106 is communicated with the first cooling pipe 3, and the water outlet 107 is communicated with the second cooling pipe 4. The antifreeze enters the first housing 104 from the water inlet 106, and the antifreeze is discharged from the water outlet 107.

[0046] Preferably, if Figure 1 and Figure 5As shown, in the embodiment, the second water chamber 2 includes a second shell 201, and the second shell 201 is arranged at the end of the cooling part through a connecting assembly 5. The structure and connection form of the second water chamber 2 and the connecting assembly 5 are the same as those of the first water chamber 1 and the connecting assembly 5. The difference is that the shape and internal structure of the second shell 201 are different from those of the first shell 104. Since the second shell 201 is only used for the flow of antifreeze, there is no partition 101 inside it, and no water inlet 106 and water outlet 107 are set outside. In addition, in order to achieve accelerated flow, the size of the second shell 201 is smaller than that of the first shell 104. The remaining structure of the second water chamber 2 and the connecting assembly 5 refers to the structure of the first water chamber 1 and the connecting assembly 5, which will not be repeated here. In addition, the structure of the connecting assembly 5 connected to the first water chamber 1 and the second water chamber 2 is exactly the same, which reduces the number of production parts and reduces management costs.

[0047] Preferably, if Figure 8 As shown, in the embodiment, the first cooling pipeline 3 and the second cooling pipeline 4 each include a plurality of cold pipes 7, and the number of cold pipes 7 of the first cooling pipeline 3 is less than the number of cold pipes 7 of the second cooling pipeline 4. In order to ensure that the high-pressure water inlet and the low-pressure water outlet are substantially similar, the number of cold pipes 7 of the first cooling pipeline 3 is less than the number of cold pipes 7 of the second cooling pipeline 4, specifically, 1-2 pipes less, thereby reducing the internal resistance of the radiator and reducing the energy consumption of the engine water pump. Figure 8 The vertical line in the figure is the center line S1.

[0048] Preferably, if Figure 1 and Figure 8 As shown, in the embodiment, the cooling part may further include a first end plate 601 and a second end plate 602 located on both sides of the cooling part, and the spacing between the partition 101 and the first end plate 601 is smaller than the spacing between the partition 101 and the second end plate 602. Since the number of cold pipes 7 of the first cooling pipe 3 is smaller than the number of cold pipes 7 of the second cooling pipe 4, the setting position of the partition 101 also needs to be adjusted accordingly to meet the flow of the antifreeze liquid.

[0049] The vehicle U-shaped flow radiator cooperates with the first water chamber, the second water chamber and the cooling part to allow the antifreeze to flow inside these three parts. The structural design of the partition allows the antifreeze in the first section and the second section of the first water chamber to flow in contact with each other in a small amount, thereby reducing the temperature difference here, reducing the uneven thermal stress on the cold pipe located in the middle, and reducing the root fracture of the cold pipe in contact with the connecting component, thereby improving the service life of the radiator. In addition, due to the structural design of the partition, there is no need to provide a press-fit seal at the partition, so there is no clamping force at this point, and it will not affect the strength of the radiator, so that the connecting component and the first water chamber will not crack in the middle, thereby improving the service life of the radiator.

[0050] In addition, according to the second aspect of the utility model, a vehicle is provided, the vehicle comprising the above-mentioned vehicle U-shaped flow radiator. During the use of the vehicle, by using the vehicle U-shaped flow radiator, the service life of the radiator can be increased, the radiator does not need to be frequently replaced, the use cost is reduced, and the user experience is improved.

[0051] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them. The protection scope of the present application is not limited thereto. Although the present application is described in detail with reference to the above-described embodiments, ordinary technicians in the field should understand that any technician familiar with the technical field can still modify the technical solutions recorded in the above-described embodiments within the technical scope disclosed in the present application, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
