[0027] The present application discloses a kind of automobile cooling pipeline assembly.

[0028] Referring to Figure 1 And Figure 2 A kind of automobile cooling pipeline assembly includes four-way valve 1, cooling pipe and exhaust pipe 5, cooling pipe is used for cooling liquid flow, in the embodiment, cooling pipe is provided with four, including cooling pipe one 2, cooling pipe two 3 and cooling pipe three 4, four-way valve 1 is communicated with cooling pipe one 2, cooling pipe two 3, cooling pipe three 4 and exhaust pipe 5 respectively, exhaust pipe 5 is provided with valve, four-way valve 1 can be operated to adjust the cooling liquid flow of cooling pipe and the gas flow of exhaust pipe 5, when cooling liquid flows from cooling pipe one 2, it is shunted to cooling pipe two 3, cooling pipe three 4 and exhaust pipe 5 by four-way valve 1, flow distribution is distributed by adjusting the size of each port of four-way valve 1, can realize cooling pipe two 3, cooling pipe four flows to cooling pipe one 2 and exhaust pipe 5, optimize arrangement space and reduce cost.

[0029] In the embodiment, cooling pipe one 2, cooling pipe two 3, cooling pipe three 4 and exhaust pipe 5 adopt hose, hose can well adapt to the shaking generated by the operation of vehicle or upper part of vehicle, avoid being damaged due to the shaking generated.

[0030] In the embodiment, cooling pipe and / or exhaust pipe 5 are provided with fixing member 6, fixing member 6 is used for detachably arranging cooling pipe and / or exhaust pipe 5 on four-way valve 1. Specifically, fixing member 6 is elastic clamp. Elastic clamp is assembled on cooling pipe and / or exhaust pipe 5, with high integration, reduces the whole vehicle assembly process. Elastic clamp can firmly connect cooling pipe, ensure the smooth flow of cooling liquid, reduce the problem of cooling liquid leakage due to connection not firm at the same time, ensure the smooth discharge of gas, reduce the propagation of vibration and noise at the same time, not only improve the assembly efficiency, but also ensure the reliability and durability of connection.

[0031] In the embodiment, the valve is a one-way valve 9, which is used to limit the backflow of gas from the exhaust pipe 5 to the four-way valve 1. The cooling liquid can flow from the cooling pipe one 2, the cooling pipe two 3, and the cooling pipe three 4 to the exhaust pipe 5 for exhaust, and the exhaust pipe 5 cannot backflow to the cooling pipe one 2, the cooling pipe two 3, and the cooling pipe three 4. The one-way valve 9 is arranged to prevent backflow after exhaust, thereby improving stability.

[0032] In the embodiment, the cooling pipe one 2 is used to communicate with the outlet of the water pump, so that the cooling liquid is pressurized and then delivered to the four-way valve 1 through the cooling pipe one 2 for flow distribution.

[0036] In the embodiment, the outer contour of the cooling pipe and / or the exhaust pipe 5 is sleeved with a protective sleeve 8. Specifically, the protective sleeve 8 is a nylon sleeve, which can prevent the cooling pipe and the exhaust pipe 5 from being physically damaged by the external environment, such as abrasion and collision. The use of the nylon sleeve can increase the overall strength of the cooling pipe and / or the exhaust pipe 5, improve the pressure resistance and service life of the cooling pipe and / or the exhaust pipe 5, and prevent the current from interfering with the cooling pipe and / or the exhaust pipe 5 due to the good insulation and high-temperature resistance of the nylon material.
