[0034] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0035] Reference below Figure 1-Figure 7 A high-pressure pipeline assembly 1000 according to an embodiment of the present invention is described, and the present invention also provides a vehicle.

[0036] Reference Figure 1-7 As shown, the high-pressure pipeline assembly 1000 of the embodiment of the utility model includes: a high-pressure pipeline 100 and two connectors 200, wherein the high-pressure pipeline 100 includes: an insulation layer 10, a core layer 11, a heat exchange layer 12 and a plurality of spoiler components 13.

[0037] The wire core layer 11 is arranged inside the insulating layer 10 and is used for electrical connection. Specifically, the insulating layer 10 is arranged on the outermost side of the high-voltage pipeline 100, and the wire core layer 11 is arranged inside the insulating layer 10. The insulating layer 10 and the wire core layer 11 adopt a conformal design to ensure that the insulating layer 10 and the wire core layer 11 are more closely combined, reducing possible gaps or cracks, thereby improving the reliability and durability of the electrical system and reducing space occupancy and weight.

[0038] The insulating layer 10 can usually be made of rubber material, which has good heat resistance and chemical resistance, can transfer the heat generated by the wire core layer 11, and can also provide protection for the wire core layer 11 to prevent the wire core layer 11 from being mechanically damaged, chemically corroded or affected by other external factors. In addition, since a high-voltage line assembly needs to be composed of multiple high-voltage pipelines 100, the insulating layer 10 can prevent the current from generating an electrical short circuit between multiple wire core layers 11, which can prevent serious consequences such as power loss, system failure, and even fire, and improve the safety of the vehicle electrical system to a certain extent.

[0039] The wire core layer 11 serves as a transmission medium for high-voltage current in the power transmission system. It can realize transmission between different high-voltage parts, such as high-voltage batteries, motors, motor controllers and other high-voltage electrical components. A large amount of heat energy will be generated during the transmission process, which is a heat source. The wire core layer 11 is usually made of conductive materials, such as copper or aluminum, to ensure that the current can be effectively transmitted and maintain efficient operation of the system.

[0040] The heat exchange layer 12 is arranged in the wire core layer 11, and a plurality of first heat exchange channels 121 extending in the axial direction are arranged in the heat exchange layer 12, and a coolant flows in the first heat exchange channels 121. The heat exchange layer 12 is used to exchange heat with the wire core layer 11, and a plurality of groups of spoiler components 13 are respectively arranged in the plurality of first heat exchange channels 121, and the spoiler components 13 are used to disturb the coolant. Specifically, the heat exchange layer 12 is arranged on the inner side of the wire core layer 11 and is arranged in close contact with the wire core layer 11, and can be used to exchange heat with the wire core layer 11. A plurality of first heat exchange channels 121 extending in the axial direction are arranged in the heat exchange layer 12, and the first heat exchange channels 121 penetrate the heat exchange layer 12 in the axial direction. A non-conductive and thermally conductive liquid medium can be used as a coolant in the first heat exchange channels 121, such as transmission oil, so as to exchange the heat of the wire core layer 11 with the coolant in the first heat exchange channels 121, control the temperature of the wire core layer 11, and improve the safety of the whole vehicle.

[0041] In addition, multiple groups of spoiler components 13 are arranged in the first heat exchange channel 121. The spoiler components 13 can disturb the coolant. Under the impact of the liquid, the spoiler components 13 can rotate. The liquid "rolls up and down" during the flow process to form turbulence, which can effectively improve the heat dissipation efficiency.

[0042] In addition, the inner side of the heat exchange layer 12 exchanges heat with the coolant, and the outer side exchanges heat with the wire core layer 11, so that the heat of the wire core layer 11 can be directly transferred to the coolant, that is, the "direct cooling mode". Compared with the traditional heat exchange structure that needs to add a heat conductive structure for heat exchange, the efficiency is improved.

[0043] That is to say, when the high-voltage current of the whole vehicle flows through the wire core layer 11 and the wire core layer 11 generates a large amount of heat under the action of the current, the "direct cooling mode" is used to make the coolant in the first heat exchange channel 121 directly exchange heat with the wire core layer 11, and then cooperate with multiple groups of spoiler components 13 to convert the horizontal flow motion of the coolant into turbulent motion, so that the heat exchange efficiency is greatly improved. The heat generated by the wire core layer 11 is transferred to the coolant through the heat exchange layer 12, and the coolant is transferred to the air through the oil cooling system heat exchanger, so that the heat is transferred from the wire core layer 11 to the atmosphere, and the temperature of the wire core layer 11 is precisely controlled. The heat exchange power of this cooling mode is relatively low, and the energy consumption of the whole vehicle is relatively small.

[0044] The two connectors 200 are respectively connected to the two ends of the high-voltage pipeline 100. Specifically, the connectors 200 at the two ends of the high-voltage pipeline 100 are used to connect the wire core layer 11 and other electrical components, and can transmit the power signal to the target device or system.

[0045] Therefore, by setting the first heat exchange channel 121 and the spoiler assembly 13, a faster and more efficient heat dissipation method is provided for the high-pressure pipeline 100, which can improve the heat dissipation speed of the high-pressure pipeline 100, solve the problem of spontaneous combustion of the whole vehicle caused by heat damage to the core layer 11 in a high temperature environment, and improve the safety of the whole vehicle.

[0046] Reference Figure 5 and Figure 7 As shown, the spoiler assembly 13 includes: a plurality of spoilers 131, and the plurality of spoilers 131 are arranged at intervals in the axial direction of the high-pressure pipeline 100. Specifically, there are a plurality of groups of spoiler assemblies 13 in the first heat exchange channel 121, and each group of spoiler assemblies 13 is composed of a plurality of flow-wrap members. In the embodiment of the utility model, each group of spoiler assemblies 13 includes three spoilers 131, and the three spoilers 131 are arranged at intervals in the axial direction of the high-pressure pipeline 100. In other embodiments, the number of spoilers 131 may also be four, five or more.

[0047] Reference Figure 5 and Figure 7As shown, multiple spoilers 131 are arranged at intervals in a direction perpendicular to the flow direction of the coolant, so that the contact area between the spoiler 131 and the coolant is maximized, and the cooling liquid disturbance efficiency is higher. In combination with the above, the multiple spoilers 131 are staggered with each other in the axial direction and the radial direction, and the straight line connecting the centers of the multiple spoilers 131 is not parallel to the axis of the high-pressure pipeline 100. This arrangement can increase the amplitude of the spoiler 131 disturbing the coolant and improve the heat exchange efficiency of the first heat exchange channel 121.

[0048] Reference Figure 7 As shown, the spoiler 131 includes: a spoiler 1311 and a connecting portion 1312, the spoiler 1311 is arranged on one end of the connecting portion 1312 and can rotate relative to the connecting portion 1312, and the other end of the connecting portion 1312 is connected to the inner wall of the heat exchange layer 12. That is, the spoiler 131 is divided into two parts: the spoiler 1311 and the connecting portion 1312, one end of the connecting portion 1312 is connected to the inner wall of the heat exchange layer 12, and the spoiler 1311 is located above the connecting portion 1312 and can rotate to disturb the coolant.

[0049] Reference Figure 2 and Figure 7 As shown, a plurality of second heat exchange channels 111 extending in the axial direction are provided in the wire core layer 11, and the second heat exchange channels 111 are used to exchange heat with the wire core layer 11. Specifically, the second heat exchange channels 111 penetrate the wire core layer 11 in the axial direction, and a refrigerant medium is placed in the second heat exchange channels 111, which can quickly absorb the heat generated by the wire core layer 11, and then release it into the atmosphere through the air conditioning system heat exchanger, so as to achieve precise temperature control of the wire core layer 11 and reduce the risk of heat damage.

[0050] Furthermore, the second heat exchange channel 111 can be cooled independently. The high voltage current of the whole vehicle flows through the wire core layer 11. The wire core layer 11 generates a large amount of heat under the action of the current. The refrigerant in the second heat exchange channel 111 is used to quickly absorb a large amount of heat from the wire core layer 11 by phase change. The heat in the refrigerant is released into the atmosphere through the air conditioning system heat exchanger, so that the temperature of the wire core layer 11 can be accurately controlled. The heat exchange power of this cooling mode is relatively high, but the compressor needs to be started, so the energy consumption of the whole vehicle is relatively high.

[0051] Alternatively, the second heat exchange channel 111 and the first heat exchange channel 121 can be cooled at the same time, using the "direct cooling mode" to allow the coolant in the first heat exchange channel 121 to directly exchange heat with the wire core layer 11, and then cooperate with multiple sets of spoiler components 13 to convert the horizontal flow motion of the coolant into turbulent motion. At the same time, the refrigerant medium in the second heat exchange channel 111 quickly absorbs the heat generated by the wire core layer 11. This mode requires starting the compressor and oil cooling system, and the energy consumption of the entire vehicle is high, but the heat exchange power is the highest. It is suitable for scenarios where the wire core layer 11 needs to be rapidly cooled when the temperature is continuously high.

[0052] Reference Figure 2 and Figure 6 As shown, the plurality of second heat exchange channels 111 are divided into a plurality of sub-heat exchange channels in the radial direction, the first liquid storage chamber 20 is divided into a plurality of sub-liquid storage chambers in the radial direction, and the plurality of sub-heat exchange channels are connected to the plurality of sub-liquid storage chambers. Specifically, the plurality of sub-heat exchange channels adopt a "quadrilateral curved surface" conformal design staggered arrangement structure, and are arranged in two circles in the radial direction of the core layer 11, in order to increase the heat exchange area, improve the heat exchange uniformity of the core layer 11, and improve the overall heat exchange efficiency.

[0053] Reference Figure 3 and Figure 5 As shown, the connector 200 is provided with a first liquid storage chamber 20 and a first inlet 21 connected to the first liquid storage chamber 20, and the first liquid storage chamber 20 is connected to the second heat exchange channel 111; and / or, the connector 200 is provided with a second liquid storage chamber 22 and a second inlet 23 connected to the second liquid storage chamber 22, and the second liquid storage chamber 22 is connected to the first heat exchange channel 121. Specifically, the connector 200 is provided with a first inlet 21 and a second inlet 23 on one side, and a first liquid storage chamber 20 and a second liquid storage chamber 22 on the other side. The connector 200 is connected to the vehicle through the first inlet 21 and the second inlet 23, and the other side is connected to the wire core layer 11 through the first liquid storage chamber 20 and the second liquid storage chamber 22, wherein the first inlet 21 is connected to the first liquid storage chamber 20, and the second inlet 23 is connected to the second liquid storage chamber 22, and the first liquid storage chamber 20 and the second liquid storage chamber 22 both play the role of buffering liquid pulses and system fluid replenishment.

[0054] In addition, multiple sub-heat exchange channels can be opened separately to reduce the power consumption of the entire vehicle while meeting the cooling needs.

[0055] Reference Figure 2 and Figure 6 As shown, the heat exchange layer 12 includes: a plurality of arcuate walls 122 and at least two straight plate walls 123, the at least two straight plate walls 123 are arranged crosswise, the two ends of the arcuate wall 122 are respectively connected to one end of the two straight plate walls 123, the arcuate wall 122 and the at least two straight plate walls 123 form a first heat exchange channel 121, and the spoiler assembly 13 is arranged on the straight plate wall 123. In the embodiment of the utility model, the heat exchange layer 12 has four arcuate walls 122 and two straight plate walls 123, the four arcuate walls 122 and the two straight plate walls 123 can separate the heat exchange layer 12 into four first heat exchange channels 121, and multiple groups of spoiler assemblies 13 are respectively arranged in several channels, wherein the connecting portion 1312 of the spoiler 131 is fixed on the straight plate wall 123.

[0056] Furthermore, a plurality of heat exchange protrusions are arranged on the outer side of the arc-shaped wall 122, and the plurality of heat exchange protrusions are arranged at intervals in the axial direction and / or the circumferential direction of the heat exchange layer 12. By providing a plurality of heat exchange protrusions in the axial direction or the circumferential direction, the roughness and irregularity of the outer surface of the heat exchange layer 12 can be increased, thereby effectively increasing the effective heat exchange surface area and improving the heat exchange efficiency.

[0057] Reference Figure 2 and Figure 6 As shown, the cross-section of the second heat exchange channel 111 can be one of a circle, an arc groove, a square, an ellipse and a star. That is, the number and form of the second heat exchange channel 111 can be designed according to the heat exchange requirement of the wire core layer 11. The greater the heat exchange, the more the number of the second heat exchange channels 111. The form of the second heat exchange channel 111 should increase the contact area with the wire core layer 11 as much as possible to improve the heat exchange efficiency.
