[0002] With the rapid development of automotive technology, society is paying increasing attention to vehicle reliability, and engine reliability is particularly important. The reliability of the engine cooling system largely determines the overall engine reliability. Several key engine components require suitable operating temperatures, so the engine needs rapid warm-up. Once the water temperature reaches a certain level, the coolant needs to enter the main circulation loop to control the water temperature, ensuring that each component operates at its optimal temperature and guaranteeing its reliability. The coolant is drawn from the radiator by a water pump and passes under pressure through the cylinder block and cylinder head to cool the components that require cooling.

[0036] In the description of this invention, "a plurality of" means two or more, and "several" means one or more.

[0037] The coolant distributor 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0038] like Figures 1-2 As shown, the coolant distributor 1 according to an embodiment of the present invention includes a distributor housing 100, a rotor 200 and a drive mechanism 300.

[0039] The distributor housing 100 has a housing inlet 110, a first housing outlet 120, and a second housing outlet 130. A rotor 200 is installed inside the distributor housing 100 and is rotatable between a first rotational position and a second rotational position relative to the distributor housing 100. The rotor 200 has a rotor inlet 210, a first rotor outlet 220, and a second rotor outlet 230 that are interconnected. A drive mechanism 300 drives the rotor 200 to rotate to the first rotational position and the second rotational position. The rotor inlet 210 is connected to the housing inlet 210 in both the first and second rotational positions. When the rotor 200 rotates to the first rotational position, the second housing outlet 130 is closed, and the first rotor outlet 220 is connected to the first housing outlet 120. When the rotor 200 rotates to the second rotational position, the first housing outlet 120 is closed, and the second rotor outlet 230 is connected to the second housing outlet 130.

[0040] Among them, such as Figure 1 and Figure 2 As shown, Figure 1 The central rotor 200 is in the first rotational position. Figure 2 The middle rotor 200 is in the second rotation position.

[0041] For example, the drive structure 300 is connected above the distributor housing 100. For instance, the upper part of the drive mechanism 300 is connected to a vacuum source such as a vacuum tank to provide driving force, while the lower part is connected to the rotor 200. When no vacuum source is connected to the coolant distributor 1, the coolant distributor 1 is in a free state, i.e., it is not acted upon by the drive mechanism 300. The rotor is in the first rotational position, and the first outlet 120 of the housing is connected to the first outlet 220 of the rotor. The coolant does not pass through the radiator and completes the circulation process, thereby quickly warming up the engine. When the drive mechanism 300 drives the rotor 200 to rotate relative to the distributor housing 100 to the second rotational position, the second outlet 130 of the housing is connected to the second outlet 230 of the rotor. The coolant passes through the radiator to complete the cooling circulation process, thereby cooling the engine.

[0042] According to an embodiment of the present invention, the coolant distributor 1 has a rotor 200 that rotates relative to the distributor housing 100 between a first rotational position and a second rotational position. The rotor has a rotor inlet 210, a rotor first outlet 220, and a rotor second outlet 230. The distributor housing 100 has a housing first outlet 120 and a housing second outlet 130. When the rotor 200 rotates to the first rotational position, the rotor first outlet 220 and the housing first outlet 120 are connected. At this time, the coolant circulates only between the cylinder block, cylinder head, and distributor via a water pump, without passing through the radiator. When the rotor 200 rotates to the second rotational position, the rotor second outlet 230 is connected to the housing second outlet 130. At this time, the coolant circulates between the cylinder block, cylinder head, distributor, and radiator via a water pump. By connecting different coolant paths relative to the distributor housing 100, the rotor 200 can quickly switch coolant flow paths. This allows all parts of the vehicle to quickly reach a suitable temperature, thereby improving the stability and reliability of the entire system.

[0043] Therefore, the coolant distributor according to the embodiments of the present invention can achieve rapid coolant distribution and has the advantages of fast coolant distribution response and high reliability.

[0044] In some specific embodiments of the present invention, such as Figures 1-2 As shown, the drive mechanism 300 includes a negative pressure device 310, a piston cylinder 320, and a transmission rod 330. The piston cylinder 320 is connected to the negative pressure device 310 and is located outside the distributor housing 100. The distributor housing 100 is constructed with a through hole 140. One end of the transmission rod 330 is connected to the piston cylinder 320, and the other end of the transmission rod 330 passes through the through hole 140 and is connected to the rotor 200. The negative pressure device 310 drives the piston cylinder 320 and the transmission rod 330 to move, thereby causing the rotor 200 to rotate relative to the distributor housing 100.

[0045] For example, the negative pressure device 310 can be a vacuum bottle. The drive structure 300 generates negative pressure through the negative pressure device 310, driving the piston cylinder 320 and the transmission rod 330 to move, thereby causing the rotor 200 to rotate relative to the distributor housing 100. Specifically, when the rotor 200 rotates between the first rotation position and the second rotation position, the coolant enters the distributor housing 100 from the same housing inlet 110. After the coolant enters the housing 100, when the rotor 200 is in the first rotation position, the rotor first outlet 220 and the housing first outlet 120 are connected; when the rotor is in the second rotation position, the rotor second outlet 230 and the housing second outlet 130 are connected, thereby realizing different coolant circulation paths and achieving efficient utilization of the coolant. Furthermore, through the rotation of the transmission rod 330, the rotor 200 rotates within the distributor housing 100, allowing the coolant to flow smoothly to the corresponding first outlet 120 and second outlet 130 of the housing, thus satisfying different conditions of the coolant distributor 1 and ensuring the normal operation of the engine cooling system 10. By controlling and adjusting the transmission rod 330 through the negative pressure device 310, the coolant flow path can be adjusted, thereby ensuring rapid adjustment of the coolant circulation path and ensuring stable engine operation within a suitable temperature range.

[0046] In some specific embodiments of the present invention, such as Figures 1-2 As shown, the piston cylinder 320 includes a piston housing 321, a piston 322, and an elastic element 323. An air chamber 301 is formed within the piston housing 321, and a negative pressure device 310 communicates with the air chamber 301. The piston 322 is housed within the piston housing 321 and seals the air chamber 301. The negative pressure device 310 drives the piston 322 to move away from the rotor 200. The elastic element 323 is connected to the piston housing 321 on the side of the piston 322 facing away from the drive rod 330.

[0047] The negative pressure generated by the negative pressure device 310 drives the piston 322 to move along a designated trajectory, thereby enabling the coolant distributor 1 to operate normally. The piston 322 is located within the air chamber 301, which is a closed space. This ensures that the negative pressure generated by the negative pressure device 310 correctly drives the piston 322. Simultaneously, the closed air chamber 301 ensures the airtightness of the piston cylinder 320, preventing external gas from entering and guaranteeing the system's efficiency and normal operation. The elastic element 323 connects the piston 322 and the negative pressure device 310, providing a certain elastic force. When the negative pressure device 310 does not provide negative pressure driving force to the cylinder 320, the elastic element 323 uses its elasticity to push the rotating rod 330 downwards, ensuring that the piston 322 maintains the correct position and stability during movement. When the coolant distributor 1 is in a free state, the piston 322 returns to its initial state due to the elastic effect of the elastic element 323. At this time, the rotor 200 also returns to its initial state to the first rotation position, thus completing the coolant circulation process.

[0048] In some specific embodiments of the present invention, such as Figures 1-2 As shown, the transmission rod 330 includes a first transmission rod 331 and a second transmission rod 332. One end of the first transmission rod 331 is connected to the piston 322 and the other end extends out of the piston housing 321. One end of the second transmission rod 332 is hinged to the other end of the first transmission rod 331, and the other end of the second transmission rod 332 extends into the coolant distributor and is hinged to the rotor 200.

[0049] Specifically, by connecting the first transmission rod 331 and the second transmission rod 332 to the piston 322 and the rotor 200 respectively, power from the piston 322 can be transmitted to the rotor 200. When the piston 322 moves, the first transmission rod 331 moves accordingly, and then the second transmission rod 332 transmits power to the rotor 200 through a hinge, driving the rotor 200 to move, thereby achieving the distribution and flow control of the coolant. Furthermore, by adjusting the position and connection method of the transmission rods, the rotor 200 can be adjusted to different positions flexibly, achieving the cooling and circulation of the coolant on various components.

[0050] In some specific embodiments of the present invention, such as Figures 1-2As shown, the rotor 200 has a clearance plane 240 on the side facing the through hole 140. The clearance plane 240 is spaced apart from the through hole 140, and the second drive rod 332 is hinged to the clearance plane 240. The clearance plane 240 provides the second drive rod 332 with room to move so as to drive the rotor 200, thereby affecting the movement state and liquid flow of the coolant distributor 1. There is a certain gap between the clearance plane 210 and the through hole 240 to prevent the rotor 200 and the second drive rod 332 from colliding with the through hole 240 during movement. If the clearance plane 210 were not present during the rotation of the rotor 200, the second drive rod 332 might come into contact with the through hole 240, causing interference and friction between them, which could affect the stability and normal operation of the system.

[0051] In some specific embodiments of the present invention, such as Figures 1-2 As shown, a flow channel 250 is constructed at the radial center of the rotor 200. The rotor inlet 210, the first rotor outlet 220, and the second rotor outlet 230 are all connected to the flow channel 250. The flow channel 250 distributes the coolant from the rotor inlet 210 to the first rotor outlet 220 and the second rotor outlet 230, ensuring uniform distribution of the coolant at different locations, increasing the coolant flow rate, and thus improving the overall cooling effect. Furthermore, by adjusting the position of the rotor 200, the flow rate of the coolant at different locations can be controlled, thereby meeting the cooling needs of different locations. This provides precise supply, ensuring that each component receives appropriate cooling.

[0052] In some specific embodiments of the present invention, such as Figures 1-2 As shown, the cross-section of the guide channel 250 is circular, while the cross-sections of the rotor inlet 210, the first rotor outlet 220, and the second rotor outlet 230 are all fan-shaped. Similarly, the cross-sections of the housing inlet 110, the first housing outlet 120, and the second housing outlet 130 are also fan-shaped. By constructing their cross-sections as fan-shaped structures, a larger opening area can be provided, thereby increasing the coolant flow rate and improving the coolant flow speed and efficiency, ensuring that the coolant can be distributed to each outlet when needed. Furthermore, the fan-shaped cross-section can better guide the coolant flow, maintaining a stable cooling flow direction and providing better fluid guidance during coolant distribution. Simultaneously, it can also evenly distribute the coolant during rotor 200 rotation, ensuring a relatively balanced coolant flow at the housing first outlet 120 and the housing second outlet 130, thereby achieving effective cooling of the engine cooling system 10.

[0053] In some specific embodiments of the present invention, such as Figures 1-2As shown, when the rotor 200 is in the first rotating position, the rotor's second outlet 230 is located between the housing's first outlet 120 and the housing's second outlet 130. When the rotor 200 is in the second rotating position, the rotor's first outlet 220 is located between the housing's first outlet 120 and the housing's second outlet 130. When the rotor 200 is in the first rotating position, the flow of coolant from the rotor's second outlet 230 can be blocked or reduced, directing it towards the rotor's first outlet 220. When the rotor 200 is in the second rotating position, the flow of coolant from the rotor's first outlet 220 can be blocked or reduced, directing it towards the rotor's second outlet 230. By controlling the rotation position of the rotor 200, the flow direction of the coolant can be adjusted, thereby allowing for more flexible control of the coolant's circulation path to achieve the best cooling effect.

[0054] An engine cooling system 10 is provided according to an embodiment of the second aspect of the present invention, such as Figure 3 As shown, the system includes the aforementioned coolant distributor 1, cylinder block 2 and cylinder head 3, water pump 4, and radiator 5. The cylinder head 3 is mounted on the cylinder block 2 and seals the cylinder block 2. The water pump 4, cylinder head 3, cylinder block 2, and coolant distributor 1 are sequentially connected to form a first circulation path. The water pump 4, cylinder head 3, cylinder block 2, coolant distributor 1, and radiator 5 are sequentially connected to form a second circulation path.

[0055] For example, the coolant distributor 1 is connected to a solenoid valve 7, which controls the rotor 200 to rotate between a first rotation position and a second rotation position according to the coolant temperature, thereby switching between the first circulation path and the second circulation path.

[0056] In the first circulation path, the coolant flows through the cylinder block 2 and cylinder head 3 via the water pump 4, bypassing the radiator 5. Since the coolant temperature is relatively low when the engine starts, it circulates directly to the water pump 4 without passing through the radiator 5, quickly warming up the engine. When the coolant temperature rises to a set value, the water temperature sensor 6 transmits a signal to the vehicle controller 8, which then sends a command to the solenoid valve 7. The solenoid valve 7 opens, connecting the vacuum source 9 to the engine cooling system 10, adjusting the coolant distributor 1. This causes the coolant to circulate through the cylinder block 2, cylinder head 3, and radiator 5 via the water pump 4 in the second circulation path. By directing the coolant flow into the radiator 5, the engine is cooled.

[0057] The engine cooling system 10 according to this embodiment has advantages such as precise control of cooling temperature and improved service life of components by utilizing the coolant distributor according to the embodiment of the present invention.
