Description

Technical Field

[0001] The utility model relates to the technical field of engines, and more specifically, to an engine water pump seat and a vehicle. Background Technique

[0002] In modern automotive engine technology, the design of the cooling system has an important impact on engine performance and reliability. The traditional engine cooling system mainly consists of multiple independent components. Among them, the water pump seat, as a key component, is responsible for installing the water pump and connecting to the coolant passage. However, most existing engine water pump seat designs have a single function and usually only have the function of installing the water pump, resulting in the need to separately design and install other related functional components. This design not only makes the layout of engine components appear redundant, but also increases the overall manufacturing cost and installation complexity.

[0003] Existing water pump seat designs often fail to meet the requirements of modern vehicles for an integrated and efficient cooling system. The functions of traditional water pump seats are repetitive, and they cannot effectively integrate components such as the thermostat, inlet pipe, and small-circulation return pipe, making the layout of the engine cooling system relatively complex. The coolant flow path is long and scattered, resulting in low cooling efficiency, increasing the maintenance difficulty and cost of the cooling system. In addition, the coordination problems between multiple independent components in traditional designs may also lead to a decrease in system reliability, thereby affecting the stability and long-term service life of the engine.

[0004] To solve these problems, there is an urgent need for an engine water pump seat with an integrated design. By integrating multiple functions into the same water pump seat, the number of components can be significantly reduced, the layout design can be simplified, and thus the overall cost of the engine can be reduced. The integrated design can not only improve the efficiency of the cooling system, but also reduce the complexity of manufacturing and installation, and improve the operating performance and reliability of the engine. By optimizing the design of the water pump seat, efficient management of the coolant passage can be achieved, meeting the high-performance requirements of modern vehicles for the engine cooling system.

[0035] Embodiment 1:

[0036] As Figures 1-6 shown, the present utility model provides a technical solution:

[0037] An engine water pump seat, on which there are provided a cylinder block mounting surface 1, a thermostat mounting surface 7 and a water pump mounting surface 8;

[0038] The engine water pump housing is mounted on the engine block through the engine block mounting surface 1. A coolant passage is provided inside the engine water pump housing, and the coolant passage communicates with the engine block;

[0039] A water pump is mounted on the water pump mounting surface 8, and the water outlet of the water pump communicates with the coolant passage; A thermostat is mounted on the thermostat mounting surface 7. The inlet end of the thermostat is connected to one end of the water pump inlet pipe, and the other end of the water pump inlet pipe is connected to the outlet of the radiator;

[0040] The engine water pump housing is further provided with a small circulation return pipe 5. One end of the small circulation return pipe 5 is connected to the engine block, and the other end of the small circulation return pipe 5 is connected to one end of a small circulation pipeline located inside the engine water pump housing. The other end of the small circulation pipeline is provided with a small circulation pipeline connection surface 9, and the thermostat communicates with the small circulation pipeline through the small circulation pipeline connection surface 9;

[0041] A seal is provided in the thermostat. The seal is configured to be able to seal or open the small circulation pipeline connection surface 9 as the thermostat opens or closes, thereby sealing or opening the small circulation pipeline; The function of the small circulation pipeline connection surface 9 is: when the engine coolant temperature rises and the thermostat opens to enter the large circulation, as the thermostat opens, the seal at the lower part of the thermostat will engage with the small circulation pipeline sealing surface, thereby sealing the small circulation pipeline and increasing the water pump efficiency and cooling efficiency.

[0042] Specifically, the thermostat is a prior art. What this application wants to protect is the structural design of the engine water pump housing. Here, in combination with Figure 5 further explain the working principle of the thermostat:

[0043] From Figure 5 it can be seen that a stepped hole 10 is provided at a position on the outer side of the thermostat mounting surface 7. A water pump inlet passage 11 and a water pump outlet passage 12 are provided between the stepped hole 10 and the small circulation pipeline connection surface 9; The water pump inlet passage 11 is connected to the inlet of the water pump, and the water pump outlet passage 12 is connected to the outlet of the water pump; The positions of the water pump inlet passage 11 and the water pump outlet passage 12 can be interchanged;

[0044] The seal of the thermostat is provided with two sealing surfaces, namely a first sealing surface and a second sealing surface; The first sealing surface and the second sealing surface are spaced apart, and there is a distance between them; The size of the first sealing surface can cover the stepped hole 10;

[0045] The first sealing surface is arranged at the stepped hole 10, and the second sealing surface is arranged at the connection surface 9 of the small circulation pipeline. The first sealing surface and the second sealing surface are respectively used to control the opening and closing states of the stepped hole 10 and the connection surface 9 of the small circulation pipeline;

[0046] When the engine coolant temperature is low and does not reach the predetermined temperature, the thermostat is closed. At this time, the first sealing surface blocks the stepped hole 10, and the second sealing surface does not block the connection surface 9 of the small circulation pipeline; at this time, the water pump inlet pipe is in a closed state, the small circulation pipeline is in an open state, the water pump inlet channel 11 and the water pump outlet channel 12 are communicated with the small circulation pipeline, and at this time, the coolant circulates inside the engine and does not go to the radiator, so that the engine coolant can be quickly heated up for warm-up;

[0047] When the engine coolant temperature is high and reaches the predetermined temperature, the thermostat is opened. At this time, the first sealing surface does not block the stepped hole 10, and the second sealing surface blocks the connection surface 9 of the small circulation pipeline; at this time, the water pump inlet pipe is in an open state, the small circulation pipeline is in a sealed state, and at this time, the coolant flows to the radiator.

[0048] In this embodiment, by integrating the coolant channel, the water pump mounting surface, the thermostat mounting surface and the small circulation return pipe, the function integration of the cooling system is realized. The thermostat controls the opening and closing of the small circulation pipeline, improves the water pump efficiency and the cooling efficiency, optimizes the overall design, and reduces the redundant components in the traditional design. To sum up, this solution reduces the engine cost and optimizes the layout design through the integrated design of the pipelines and channels on the engine water pump housing.

[0049] Embodiment 2:

[0050] On the basis of Embodiment 1, referring to Figures 1-6 , the connection surface 9 of the small circulation pipeline is a hollow structure. One side of the seal close to the connection surface 9 of the small circulation pipeline is a plane, that is, the second sealing surface. The size of the plane can cover the hollow part of the connection surface 9 of the small circulation pipeline, so that the seal can block the hollow part of the connection surface 9 of the small circulation pipeline, thereby sealing the small circulation pipeline; the seal here can be a flange.

[0051] Furthermore, the body mounting surface 1 and the thermostat mounting surface 7 are respectively arranged at the front and rear ends of the engine water pump housing, the water pump mounting surface 8 is arranged at the right end of the engine water pump housing, and the small circulation return pipe 5 is arranged at the top of the engine water pump housing.

[0052] Further, an EGR return water pipe 2 is provided at the left end of the engine water pump seat. One end of the EGR return water pipe 2 communicates with the coolant passage, and the other end of the EGR return water pipe 2 is connected to the exhaust gas recirculation system.

[0053] Further, a water pump makeup water pipe 4 is provided at the top of the engine water pump seat. One end of the water pump makeup water pipe 4 communicates with the water inlet of the water pump, and the other end of the water pump makeup water pipe 4 is connected to the expansion tank.

[0054] Further, a warm air return water pipe 6 is provided at the top of the engine water pump seat. One end of the warm air return water pipe 6 communicates with the coolant passage, and the other end of the warm air return water pipe 6 is connected to the in-vehicle warm air system.

[0055] Further, an oil cooler return water passage 3 is formed by inward extension at the top of the engine water pump seat. One end of the oil cooler return water passage 3 communicates with the coolant passage, and the other end of the oil cooler return water passage 3 is connected to the oil cooler.

[0056] Further, the EGR return water pipe 2, the oil cooler return water passage 3, the water pump makeup water pipe 4, the small circulation return water pipe 5, and the warm air return water pipe 6 are all located downstream of the thermostat, so that when in small circulation, the above pipelines and passages are all filled with coolant.

[0057] Further, the thermostat mounting surface 7 is provided with at least two threaded holes, and the thermostat is fixedly mounted on the thermostat mounting surface 7 by bolts.

[0058] Further, the water pump mounting surface 8 is provided with at least three threaded holes, and the water pump is fixedly mounted on the water pump mounting surface 8 by bolts.
