[0029] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0030] To balance high flow resistance and low noise, this application proposes a flow-blocking structure for the coolant circuit of a vehicle thermal management system. This structure, using a sieve-like design, achieves both high flow resistance and low noise. For details, please refer to... Figure 2a and Figure 2b , Figure 2a This paper shows a schematic diagram of a flow-blocking structure for a coolant circuit in a vehicle thermal management system according to an embodiment of this application. Figure 2b It shows Figure 2a A schematic diagram of the BB' section of the throttling structure.

[0031] like Figure 2a and Figure 2b As shown, the interception structure 20 may include:

[0032] The columnar body 21 has multiple flow-cutting holes 22 that penetrate through it.

[0033] In this embodiment, the flow-blocking structure 20 can be located at the throttling point of the coolant circuit; wherein, the throttling point can refer to the location of the pipe 30 in the coolant circuit that needs to be throttled; for example, such as Figure 3 The diagram shows a throttling point 40 according to an embodiment of this application; of course, the embodiment of this application does not impose specific restrictions on the location of the throttling point.

[0034] The intercepting structure 20 can be composed of a columnar body 21, the size of which can be set according to the inner diameter of the pipeline 30 at the throttling point of the actual application, and the specific shape of the columnar body 21 can also be set according to the specific shape of the pipeline 30 at the throttling point of the actual application.

[0035] For example, if the pipeline 30 at the throttling point to which the intercepting structure 20 is applied is cylindrical, the columnar body 21 of the intercepting structure 20 can also be cylindrical.

[0036] A plurality of intercepting holes 22 can be arranged in the columnar body 21, which can be parallel to the vertical axis of the columnar body 21, and each intercepting hole 22 penetrates the columnar body 21. Among them, the vertical axis can be parallel to the flow direction of the cooling liquid in the pipeline 30 where the intercepting structure 20 is located.

[0037] For example, the intercepting hole 22 can also penetrate the columnar body 21 in other forms, such as an acute angle with the vertical axis. It should be noted that the arrangement of the intercepting hole 22 needs to ensure that the cooling liquid can move from one end of the columnar body 21 to the other end.

[0038] By increasing the number of intercepting holes 22 and increasing the resistance loss along each intercepting hole 22, the flow resistance of the entire intercepting structure 20 is increased, thereby increasing the total intercepting area. After the total intercepting area is increased, the flow rate of the cooling liquid can be reduced, thereby reducing the noise of the cooling liquid flowing through this place.

[0039] In an embodiment of the present application, the diameter of the intercepting hole 22 can range from 2mm to 3mm.

[0040] In an embodiment of the present application, the number of intercepting holes 22 can range from 5 to 7.

[0041] In an embodiment of the present application, the length of the intercepting hole 22 can range from 25mm to 30mm.

[0042] In some feasible embodiments, considering the adaptation with the cooling water pipe and the fact that the sieve-shaped hole will not be blocked by impurities in the cooling liquid during use, the diameter of the intercepting hole 22 can be designed to be between 2mm and 3mm, the number can be controlled to be between 5 and 7, and the length can be designed to be between 25mm and 30mm.

[0043] In other feasible embodiments, the number of intercepting holes 22 can also be designed to be 3, and the length can be designed to be less than 25mm, which can be set according to actual needs.

[0044] In actual application, the diameter designed to be between 2mm and 3mm can avoid being too small to be easily blocked by impurities, and also avoid being too large to be processed and manufactured.

[0045] The number of holes is designed to be 5-7, which can avoid too few holes to cause too much noise, and too many holes to be unable to be processed.

[0046] The length is designed to be 25mm-30mm, which can avoid too long length to be unable to assemble the intercepting structure 20 into the pipeline 30.

[0047] The following are experimental results corresponding to some of the above data:

[0048] When the number of holes is 3, the hole diameter is 2mm, and the length is 25mm, the cooling liquid flow rate is 3m / s, the flow resistance is 5kPa, and the noise measured is 25dB.

[0049] When the number of holes is 5, the hole diameter is 2mm, and the length is 25mm, the cooling liquid flow rate is 2m / s, the flow resistance is 10kPa, and the noise measured is 20dB.

[0050] When the number of holes is 6, the hole diameter is 2mm, and the length is 25mm, the cooling liquid flow rate is 2m / s, the flow resistance is 10kPa, and the noise measured is 20dB.

[0051] When the number of holes is 7, the hole diameter is 2mm, and the length is 25mm, the cooling liquid flow rate is 2m / s, the flow resistance is 10kPa, and the noise measured is 20dB.

[0052] When the hole diameter is 2mm, the number of holes is 5, and the length is 25mm, the cooling liquid flow rate is 2m / s, the flow resistance is 10kPa, and the noise measured is 20dB.

[0053] When the hole diameter is 3mm, the number of holes is 5, and the length is 25mm, the cooling liquid flow rate is 2m / s, the flow resistance is 10kPa, and the noise measured is 20dB.

[0054] When the length is 20mm, the hole diameter is 2mm, and the number of holes is 5, the cooling liquid flow rate is 4m / s, the flow resistance is 4kPa, and the noise measured is 27dB.

[0055] When the length is 25mm, the hole diameter is 2mm, and the number of holes is 5, the cooling liquid flow rate is 4m / s, the flow resistance is 4kPa, and the noise measured is 20dB.

[0056] When the length is 30mm, the hole diameter is 2mm, and the number of holes is 5, the cooling liquid flow rate is 4m / s, the flow resistance is 4kPa, and the noise measured is 20dB.

[0057] In an embodiment of the present application, the intercepting structure 20 can further include:

[0058] The fixing component is used to fix the columnar main body 21 at the throttling point.

[0059] In some possible embodiments, the intercepting component can further include a fixing component for fixing the columnar body 21 inside the pipeline 30 corresponding to the throttling point, so as to fix the intercepting structure 20 in the pipeline 30; the fixing component can be arranged independently of the columnar body 21, for example, as shown in Figure 4

[0060] The fixing component can be a clamp 23; if the fixing component is the clamp 23, the columnar body 21 can be located inside the pipeline 30 of the throttling point of the cooling liquid circuit, and the clamp 23 can be located outside the pipeline 30 of the throttling point of the cooling liquid circuit and correspond to the columnar body 21. After the columnar body 21 is inserted into the pipeline 30 of the throttling point, the columnar body 21 can be fixed inside the pipeline 30 of the throttling point of the cooling liquid circuit by the hoop clamp 23 outside the pipeline 30 of the throttling point of the cooling liquid circuit corresponding to the columnar body 21. In addition, when the intercepting structure 20 needs to be cleaned, the intercepting structure 20 can also be disassembled by removing the clamp 23, thereby improving the practicability of the intercepting structure 20.

[0061] In some possible embodiments, the fixing component can also be connected with the columnar body 21 together, for example:

[0062] The columnar body 21 can be provided with an expansion structure outside, which can expand after contacting the cooling liquid when the columnar body 21 is inserted into the pipeline 30 corresponding to the throttling point, so as to fix the columnar body 21 inside the pipeline 30 of the throttling point. The specific form of the fixing structure is not limited in the embodiments of the present application.

[0063] In some possible embodiments, the intercepting structure 20 can also not be provided with the fixing component, but be directly fixed in the pipeline 30 of the cooling liquid circuit; for example, the intercepting structure 20 can be welded in the pipeline 30, or be directly stuffed in the pipeline 30, which is not limited in the embodiments of the present application.

By increasing the number of the intercepting holes 22, the flow resistance loss of each intercepting hole 22 is increased, and then the flow resistance of the entire intercepting structure 20 is increased, so that the total intercepting area is increased; after the total intercepting area is increased, the flow rate of the cooling liquid can be reduced, and then the noise of the cooling liquid flowing through the place can be reduced.
