Description

Technical Field

[0001] The present disclosure relates to the technical field of engine cooling, and particularly to a pipeline module and a vehicle. Background Art

[0002] The engine of an automobile is an indispensable component in the power system of the automobile. When the engine is working, it needs to be cooled. Usually, a cooling system is connected to the engine. The cooling system of the engine generally includes a thermostat, a radiator, and a water pump. The thermostat is connected to the radiator, the water pump, and the engine, so that the water pump can drive the coolant to circulate between the engine housing and the radiator to control the temperature of the engine housing. Moreover, components such as the heater system and the supercharger of the automobile are also connected to the pipeline between the thermostat, the water pump, and the radiator, so that the water pump can drive the coolant to flow through components such as the heater system and the supercharger to control the temperature of various components of the automobile; however, when the coolant flows in the cooling system, gas is easily introduced into the coolant, resulting in bubbles in the coolant and affecting the heat exchange effect. Therefore, exhaust pipes are usually provided on components such as the engine housing, the heater system, and the supercharger respectively, so that when the coolant flows through components such as the engine housing, the heater system, and the supercharger, the bubbles in the coolant can be discharged through the exhaust pipes of each component, ensuring the cooling effect when the coolant flows through components such as the engine housing, the heater system, and the supercharger.

[0003] However, providing exhaust pipes on components such as the engine housing, the heater system, and the supercharger respectively occupies the space around the engine, and multiple exhaust pipes also need to avoid each other with the pipelines of the cooling system, resulting in difficult assembly operations for the engine and surrounding components.

[0031] In order to more clearly understand the above-mentioned objects, features and advantages of the present disclosure, the solution of the present disclosure will be further described below. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0032] Many specific details are set forth in the following description in order to provide a thorough understanding of the present disclosure, but the present disclosure may be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all of the embodiments.

[0033] Referring to Figures 1 to 3 As shown, the embodiment of the present disclosure provides a pipeline module, including a main body 1, a thermostat 2 and an exhaust pipe 3; the thermostat 2 is connected to the main body 1, the main body 1 is provided with a first channel 11 and a second channel 12, one end of the first channel 11 is used to communicate with the engine housing 4, the other end is communicated with the thermostat 2, and the thermostat 2 is used to communicate with the radiator 5 and the water pump 6; one end of the second channel 12 is used to communicate with the engine housing 4, and the other end is used to communicate with the water pump 6; the thermostat 2 is provided with a first pipeline 21 and a second pipeline 22 communicated with the thermostat 2, the main body 1 is provided with a third pipeline 23 communicated with the second channel 12, the first pipeline 21 is used to communicate with the heating system 8 and the supercharger 7, the second pipeline 22 is used to communicate with the heating system 8, and the third pipeline 23 is used to communicate with the supercharger 7; the exhaust pipe 3 is communicated with the top side of the thermostat 2 and is located above the first channel 11, the first pipeline 21 and the second pipeline 22.

[0034] Specifically, the thermostat 2 is used to control the large and small coolant cycles of the engine. The thermostat 2 is provided with three openings, which are respectively connected to the engine's cooling water circuit, radiator 5, and water pump 6. When the engine is just started, the engine does not need to cool down quickly, and at this time, it is in the small cycle state. The coolant in the engine's cooling water circuit flows into the water pump 6 through the thermostat 2 and then flows back into the engine's cooling water circuit through the water pump 6. When the engine has been working for some time and its temperature rises, it is necessary to make the coolant enter the large cycle. That is, the thermostat 2 guides the coolant in the engine's cooling water circuit into the radiator 5. The radiator 5 is connected to the water pump 6, and the coolant in the radiator 5 flows back into the engine's cooling water circuit through the water pump 6 after heat dissipation.

[0035] The above-mentioned thermostat 2 is also provided with through holes corresponding to the first pipeline 21 and the second pipeline 22, so that one end of the first pipeline 21 can be communicated with the inside of the thermostat 2 through a through hole, and one end of the second pipeline 22 can be communicated with the inside of the thermostat 2 through another through hole. The first pipeline 21 is connected to the heating system 8, and the second pipeline 22 is connected to the heating system 8. That is, the first pipeline 21, the second pipeline 22, the thermostat 2, the engine housing 4, and the heating system 8 can form a loop, enabling the coolant to flow in the loop formed by the first pipeline 21, the second pipeline 22, the heating system 8, and the thermostat 2.

[0036] The above-mentioned first pipeline 21 is also connected to the supercharger 7, and the third pipeline 23 is connected to the supercharger 7 on the second channel 12, so that the first pipeline 21, the thermostat 2, the engine housing 4, the supercharger 7, and the third pipeline 23 form a loop, and the coolant can flow in the loop.

[0037] The above-mentioned heating system 8 needs to utilize the heat generated by the engine, and the supercharger 7 generates heat during operation and needs to be cooled down. Therefore, when the pipeline module is working, when the thermostat 2 makes the engine's coolant in the large cycle state, the coolant enters the engine housing 4 from the second channel 12 through the radiator 5 and the water pump 6. When the coolant passes through the second channel 12, it flows into the supercharger 7 through the third pipeline 23. After the coolant flows from the radiator 5 into the supercharger 7, it cools down the supercharger 7, and then the coolant that has completed cooling the supercharger 7 flows into the thermostat 2 through the first pipeline 21. The coolant that enters the engine housing 4 through the second channel 12 absorbs the heat of the engine housing 4, and the temperature of the coolant rises after absorbing the heat of the engine housing 4. Then, the coolant with the increased temperature flows into the thermostat 2 through the first channel. The coolant with a higher temperature that flows into the thermostat 2 flows into the heating system 8 through the second pipeline 22. The coolant that has passed through the heating system 8 flows back into the thermostat 2 through the first pipeline 21, and the coolant in the thermostat 2 then flows into the radiator 5 for heat dissipation, thus completing the circulating flow of the coolant.

[0038] When the thermostat 2 is in the small circulation state, the coolant flows from the engine housing 4 into the thermostat 2, then into the water pump 6. The coolant flowing into the water pump 6 flows into the engine housing 4 through the second channel 12. During this process, the coolant flowing into the thermostat 2 flows into the heating system 8 through the first pipeline 21, and then flows back into the thermostat 2 through the second pipeline 22. The coolant flowing into the second channel 12 flows into the supercharger 7 through the third pipeline 23, and then flows back into the thermostat 2 through the first pipeline 21.

[0039] One end of the above exhaust pipe 3, which is arranged vertically away from the thermostat 2, can be selected as an open end, so that the exhaust pipe 3 connects the inside of the thermostat 2 with the external environment. The gas in the coolant in the thermostat 2 can automatically be discharged from the thermostat 2 through the exhaust pipe 3 under the action of buoyancy.

[0040] The above exhaust pipe 3 extends vertically away from the thermostat 2 on the thermostat 2, and the exhaust pipe 3 is on the side of the thermostat 2 away from the ground. The connection between the exhaust pipe 3 and the thermostat 2 is located above the first channel 11, the second channel 12, the first pipeline 21 and the second pipeline 22 in the vertical direction; the coolant fills the first channel 11, the second channel 12, the first pipeline 21 and the second pipeline 22. The gas in the coolant will be affected by the buoyancy of the coolant and move upward. The coolant in the first channel 11, the first pipeline 21 and the second pipeline 22 will all converge into the thermostat 2, so that the gas in the first channel 11, the first pipeline 21 and the second pipeline 22 moves to the thermostat 2 along with the coolant; that is, the gas in the first channel 11, the first pipeline 21 and the second pipeline 22 is discharged through the exhaust pipe 3 in a centralized manner, and then the coolant in the thermostat 2 circulates through the first channel 11, the first pipeline 21 and the second pipeline 22 to the engine housing 4, the heating system 8 and the supercharger 7 for temperature control.

[0041] An EGR (Exhaust Gas Recirculation) cooler can be optionally connected in series on the above heating system 8. The first pipeline 21 and the second pipeline 22 are respectively connected to the EGR cooler 81. The coolant enters the EGR cooler 81 through the second pipeline 22 and then flows into the heating system 8, and then the coolant flows into the EGR cooler 81 from the heating system 8 and then flows back to the thermostat 2 through the first pipeline 21.

[0042] When the pipeline module provided by the embodiment of the present disclosure is specifically used, the main body 1 is connected to the engine housing 4, the first channel 11 is communicated with the engine housing 4, the two openings of the thermostat 2 are respectively communicated with the radiator 5 and the water pump 6, and the radiator 5 and the water pump 6 are connected in series. The first pipeline 21 is communicated with the heating system 8 and the supercharger 7, the second pipeline 22 is communicated with the heating system 8, the third pipeline 23 is communicated with the supercharger 7, and the exhaust pipe 3 is communicated with the top side of the thermostat 2.

[0043] When the thermostat 2 is in the large circulation state, the coolant passes through the radiator 5 and the water pump 6 and enters the engine housing 4 from the second passage 12. When the coolant passes through the second passage 12, it flows into the supercharger 7 through the third pipeline 23 to cool the supercharger 7. The coolant that has completed cooling the supercharger 7 flows into the thermostat 2 through the first pipeline 21. The coolant that enters the engine housing 4 through the second passage 12 absorbs the heat of the engine housing 4, and the temperature of the coolant rises. The coolant with the increased temperature flows into the thermostat 2 through the first passage 11. The coolant with a higher temperature that flows into the thermostat 2 flows into the heating system 8 through the second pipeline 22. The coolant that has passed through the heating system 8 flows back to the thermostat 2 through the first pipeline 21. The coolant in the thermostat 2 then flows into the radiator 5 for heat dissipation, thus completing the circulating flow of the coolant.

[0044] When the thermostat 2 is in the small circulation state, the coolant flows from the engine housing 4 into the thermostat 2, and then into the water pump 6. The coolant that flows into the water pump 6 flows into the engine housing 4 through the second passage 12. During this process, the coolant that flows into the thermostat 2 flows into the heating system 8 through the first pipeline 21 and then flows back to the thermostat 2 through the second pipeline 22. The coolant that flows into the second passage 12 flows into the supercharger 7 through the third pipeline 23 and then flows back to the thermostat 2 through the first pipeline 21.

[0045] The pipeline module provided by the embodiments of the present disclosure includes a main body portion 1, a thermostat 2, and an exhaust pipe 3; the thermostat 2 is connected to the main body portion 1, and the main body portion 1 is provided with a first channel 11 and a second channel 12. One end of the first channel 11 is used to communicate with the engine housing 4, and the other end is communicated with the thermostat 2, and the thermostat 2 is used to communicate with the radiator 5 and the water pump 6; one end of the second channel 12 is used to communicate with the engine housing 4, and the other end is used to communicate with the water pump 6, so that the thermostat 2 forms a small circulation water path of the engine through the first channel 11 and the second channel 12, and the first channel 11, the thermostat 2, the radiator 5, the water pump 6, and the second channel 12 can also form a large circulation water path of the engine; the thermostat 2 is provided with a first pipeline 21 and a second pipeline 22 communicated with the thermostat 2, and the main body portion 1 is provided with a third pipeline 23 communicated with the second channel 12. The first pipeline 21 is used to communicate with the heating system 8 and the supercharger 7, the second pipeline 22 is used to communicate with the heating system 8, and the third pipeline 23 is used to communicate with the supercharger 7, so that the coolant can flow through the heating system 8 and the supercharger 7 through the first pipeline 21, the second pipeline 22, and the third pipeline; the exhaust pipe 3 is communicated with the top side of the thermostat 2 and is located above the first channel 11, the first pipeline 21, and the second pipeline 22. The pipeline module enables the engine housing 4, the heating system 8, and the supercharger 7 to communicate with each other, and the coolant will converge into the thermostat 2 during the circulating flow process, so that exhausting the thermostat 2 through the exhaust pipe 3 can centrally exhaust the coolant flowing into the engine housing 4, the heating system 8, and the supercharger 7, avoiding the problem of occupying the space around the engine by separately arranging exhaust structures on the engine housing 4, the heating system 8, and the supercharger 7, and the assembly difficulty caused by mutual interference, and simplifying the assembly operation of the engine and its surrounding components.

[0046] Referring Figure 1 and Figure 2 As shown, in some embodiments, the first pipeline 21 includes a heating system drain pipe 211 and a supercharger drain pipe 212. One end of the heating system drain pipe 211 is communicated with the thermostat 2, and the other end is used to communicate with the heating system 8. One end of the supercharger drain pipe 212 is communicated with the first channel 11, and the other end is communicated with the supercharger 7. With such a setting, on the basis of connecting the heating system drain pipe 211 with the heating system 8 and the supercharger drain pipe 212 with the supercharger 7, the supercharger drain pipe 212 is communicated with the heating system drain pipe 211, so that the coolant enters the heating system drain pipe 211 through the supercharger drain pipe 212 and then enters the thermostat 2, simplifying the structure of the first pipeline 21.

[0047] Specifically, the drain pipe 211 of the warm air system may be selected to extend along the direction of the thermostat 2 towards the main body 1. The drain pipe 211 of the warm air system is connected to the water outlet of the warm air system 8, and the second pipeline 22 is connected to the water inlet of the warm air system 8. The coolant flows from the water outlet of the warm air system 8 into the drain pipe 211 of the warm air system and then into the thermostat 2. The coolant in the thermostat 2 enters the warm air system 8 through the second pipeline 22; the third pipeline 23 is communicated with the water inlet of the supercharger 7, and the supercharger drain pipe 212 is communicated with the water outlet of the supercharger 7. The water pump 6 inputs the coolant into the second channel 12. The coolant enters the supercharger 7 through the third pipeline 23. The coolant absorbs heat in the supercharger 7 and enters the drain pipe 211 of the warm air system through the supercharger drain pipe 212, and then enters the thermostat 2 through the drain pipe 211 of the warm air system.

[0048] Referring to Figure 1 and Figure 2 As shown, in some embodiments, the thermostat 2 includes a housing and a movable valve; a first chamber and a second chamber are formed in the housing. The first chamber and the second chamber are connected through a communication hole. The housing is provided with a first opening, a second opening 24, and a third opening 25. The first opening and the second opening 24 are both communicated with the first chamber, and the third opening 25 is communicated with the second chamber. The first channel 11 is communicated with the first opening, the second opening 24 is communicated with the water pump 6, the third opening 25 is communicated with the radiator 5, and the movable valve is arranged on the communication hole to control the communication and isolation between the first chamber and the second chamber; the first pipeline 21 is communicated with both the first chamber and the second chamber, the second pipeline 22 is communicated with both the first chamber and the second chamber, and the exhaust pipe 3 is arranged on the top side of the housing, and the exhaust pipe 3 is communicated with both the first chamber and the second chamber. With such a setting, the opening and closing of the movable valve control the small cycle and the large cycle of the external cooling water circuit of the engine, and the coolant in either the first chamber or the second chamber can enter the first pipeline 21 and the second pipeline 22, and the coolant in either the first chamber or the second chamber can discharge the gas out of the thermostat 2 through the exhaust pipe 3.

[0049] Specifically, it may be selected that a first chamber and a second chamber are formed inside the housing of the thermostat 2. The first opening is arranged on the side close to the main body 1, so that the end of the first channel 11 extends to the first opening to communicate the first opening with the first channel 11. The second opening 24 is communicated with the water pump 6 through a pipeline, and the third opening 25 is communicated with the radiator 5 through a pipeline.

[0050] When the engine is just started, the engine needs to increase its temperature. At this time, the movable valve is in the closed state, the first chamber and the second chamber are isolated from each other, and the coolant enters the first chamber from the engine housing 4 through the first channel 11, and then flows into the water pump 6 through the second opening 24. The coolant flows into the second channel 12 through the water pump 6. At this time, the coolant does not pass through the radiator 5, and the temperature of the engine can continue to rise, that is, the thermostat 2 makes the coolant in the small cycle of the engine. When the coolant is in the small cycle, after entering the thermostat 2 from the engine housing 4, the coolant in the thermostat 2 flows through the heating system 8 through the first pipeline 21 and the second pipeline 22. The coolant absorbs heat from the engine housing 4 and flows into the heating system 8, enabling the heating system 8 to utilize the heat generated by the operation of the engine housing 4; and a part of the coolant entering the second channel 12 enters the supercharger 7 through the third pipeline 23 and then flows back into the thermostat 2 through the first pipeline 21.

[0051] After the engine has been started for a period of time, the engine needs to reduce its temperature. At this time, the movable valve is opened, and the coolant enters the first chamber from the engine housing 4 through the first channel 11, and then the coolant enters the second chamber through the communication hole. The coolant in the second chamber enters the radiator 5 through the third opening 25. After being cooled by the radiator 5, the coolant enters the water pump 6. The coolant in the water pump 6 enters the second channel 12 and then enters the engine housing 4. At this time, the coolant passes through the radiator 5, enabling the coolant to continuously reduce the temperature of the engine, that is, the thermostat 2 makes the coolant in the large cycle of the engine. When the coolant is in the large cycle, after entering the thermostat 2 from the engine housing 4, the coolant in the thermostat 2 flows through the heating system 8 through the first pipeline 21 and the second pipeline 22. The coolant absorbs heat from the engine housing 4 and flows into the heating system 8, enabling the heating system 8 to utilize the heat generated by the operation of the engine housing 4; and a part of the coolant entering the second channel 12 enters the supercharger 7 through the third pipeline 23 and then flows back into the thermostat 2 through the first pipeline 21. The coolant entering the second channel 12 is the coolant cooled by the radiator 5, that is, the coolant can cool the supercharger 7 after flowing through the supercharger 7 from the second channel 12.

[0052] In the above-mentioned housing, a first connection channel, a second connection channel, and a third connection channel can be selectively provided. One end of the first connection channel has two branches, and the two branches are respectively communicated with the first chamber and the second chamber. The other end of the first connection channel is communicated with the first pipeline 21, so that the first pipeline 21 is communicated with both the first chamber and the second chamber; one end of the second connection channel has two branches, and the two branches are respectively communicated with the first chamber and the second chamber. The other end of the second connection channel is communicated with the second pipeline 22; one end of the third connection channel has two branches, and the two branches are respectively communicated with the first chamber and the second chamber. The other end of the third connection channel is communicated with the exhaust pipe 3.

[0053] The above-mentioned coolant flows in the thermostat 2. The coolant can flow into the first pipeline 21 in either the first chamber or the second chamber, and the coolant can flow into the second pipeline 22 in either the first chamber or the second chamber. Moreover, the gas in the coolant in the first chamber and the second chamber can be discharged from the thermostat 2 through the exhaust pipe 3.

[0054] The above-mentioned movable valve can be selected as the valve of the wax-type thermostat. The wax in the wax-type thermostat valve melts or solidifies when the temperature changes, thereby driving the valve to open and close. Of course, the movable valve can also be selected as an electronic valve. The electronic valve is connected to the temperature detector in the thermostat 2. When the temperature of the coolant in the thermostat 2 reaches the set temperature, the electronic valve opens. When the temperature of the coolant in the thermostat 2 is lower than the set temperature, the electronic valve closes.

[0055] Referring to Figure 1 and Figure 2 As shown, in some embodiments, a temperature detector 26 is installed on the thermostat 2. With such a setting, the temperature detector 26 can monitor the temperature of the coolant in the thermostat 2.

[0056] Specifically, it can be selected that a through hole is provided on the housing of the thermostat 2, and the temperature detector 26 is inserted into the through hole. The temperature detector 26 blocks the channel, and the detection end of the temperature detector 26 is located inside the thermostat 2. The temperature detector 26 detects the temperature inside the thermostat 2. The temperature detector 26 can be selected to be connected to the vehicle's on-board computer, so that the vehicle's on-board computer can detect the temperature of the coolant in the thermostat 2. Of course, the movable valve can also be selected as an electronic valve, and the electronic valve is electrically connected to the temperature detector 26, so that the electronic valve opens and closes according to the detection result of the temperature detector 26.

[0057] Referring to Figure 1 and Figure 2 As shown, in some embodiments, a fitting surface 13 is formed on one side of the main body portion 1. The fitting surface 13 is used for fitting and connecting with the engine housing 4. The first channel 11 forms an engine water outlet on the fitting surface 13, and the engine water outlet is communicated with the engine housing 4; one end of the second channel 12 away from the water pump 6 forms an engine water inlet 121 on the fitting surface 13, and the engine water inlet 121 is communicated with the engine housing 4. With such a setting, when the fitting surface 13 is fitted with the engine housing 4, the engine water outlet and the engine water inlet 121 can be communicated with the engine housing 4, facilitating the coolant to flow between the first channel 11 and the second channel 12 through the engine water outlet and the engine water inlet 121.

[0058] Specifically, a fitting surface 13 is provided on the main body portion 1. The fitting surface 13 fits with the engine housing 4. The interior of the engine housing 4 has a cooling cavity. The engine housing 4 is provided with a first water jacket port and a second water jacket port that communicate with the cooling cavity. The first water jacket port is disposed opposite to and communicates with the engine water outlet. The second water jacket port is disposed opposite to and communicates with the engine water inlet 121. The coolant in the cooling cavity within the engine housing 4 enters the thermostat 2 through the second water jacket port and the engine water inlet. The coolant in the water pump 6 enters the second channel 12. The coolant in the second channel 12 enters the cooling cavity of the engine housing 4 through the engine water inlet 121 and the second water jacket port. The coolant in the cooling cavity of the engine housing 4 enters the first channel 11 through the first water jacket port and the engine water outlet.

[0059] The above-mentioned main body portion 1 can be connected to the engine housing 4 by welding. Of course, the main body portion 1 and the engine housing 4 can also be connected by bolts. Sealing rings are provided around the engine water outlet on the fitting surface 13. The sealing rings are arranged around the engine water outlet. Sealing rings are provided around the engine water inlet 121. The sealing rings are arranged around the engine water inlet 121. After the fitting surface 13 is fitted and connected to the engine housing 4, the sealing ring around the engine water outlet fits with the engine housing 4 to enable the second water jacket port to be sealed and communicate with the engine water inlet 121, and the first water jacket port to be sealed and communicate with the engine water outlet.

[0060] Refer to Figure 1 and Figure 2 As shown, in some embodiments, the engine water outlet includes a first water outlet 111 and a second water outlet 112. The first water outlet 111 is used to communicate with the cylinder block of the engine housing 4. The second water outlet 112 is used to communicate with the cylinder head of the engine housing 4. With such a setting, the first water outlet 111 and the second water outlet 112 can be respectively used to receive the coolant discharged from the cylinder block and the cylinder head, and enable the coolant discharged from the cylinder head and the cylinder block to enter the first channel 11 and flow into the thermostat 2, so that the pipeline module adapts to the cooling water circuits of the cylinder head and the cylinder block of the engine housing 4.

[0061] Specifically, the engine housing 4 includes a cylinder head and a cylinder block. The cylinder head has a water circuit inside, and the cylinder block has a water circuit inside. The coolant can flow in the water circuit in the cylinder head and the water circuit in the cylinder block. Both the cylinder block and the cylinder head of the engine housing 4 communicate with the second water jacket port on the engine housing 4, enabling the coolant to enter the cylinder block and the cylinder head respectively through the second water jacket port.

[0062] The first water jacket opening of the above-mentioned engine housing 4 includes a cylinder head opening and a cylinder block opening. The water passage inside the cylinder block forms the cylinder block opening on the surface of the cylinder block, and the water passage inside the cylinder head forms the cylinder head opening on the surface of the cylinder head. The first passage 11 can be selected as a passage formed inside the main body 1. There are two through holes provided on the mating surface 13, and the two through holes are respectively communicated with the first passage 11, and the two through holes serve as the first water outlet 111 and the second water outlet 112 respectively. The first water outlet 111 is in contact with and communicated with the cylinder block opening, and the second water outlet 112 is in contact with and communicated with the cylinder head opening.

[0063] Referring to Figure 1 and Figure 2 As shown, in some embodiments, a sealing portion 14 is provided on the mating surface 13, and the sealing portion 14 is used to block the process hole of the engine housing 4. With this arrangement, when the mating surface 13 is in contact with the engine housing 4, the sealing portion 14 can block the process hole of the engine housing 4, simplifying the operation of the sealing portion 14 to block the process hole.

[0064] Specifically, the process hole on the engine housing 4 can be selected as the opening formed by the intake manifold small load passage on the engine housing 4. The process hole is communicated with the intake manifold. After the engine is installed, this process hole needs to be blocked to prevent foreign objects and dust from entering the intake manifold. The sealing portion 14 can be selected as a convex block on the mating surface 13, and the protrusion can be inserted into the process hole to block the process hole. Of course, the sealing portion 14 can also be selected as a rectangular area on the mating surface 13, and a sealing strip is provided at the edge of the rectangular area. When the mating surface 13 is in contact with the engine housing 4, the sealing strip at the edge of the rectangular area is in contact with the periphery of the process hole, and the rectangular area covers the process hole, so that the sealing portion 14 blocks the process hole.

[0065] Referring to Figure 1 and Figure 2 As shown, in some embodiments, the thermostat 2 is arranged at one end of the main body 1, the second passage 12 is formed at the other end of the main body 1, and the first passage 11 is arranged between the thermostat 2 and the second passage 12. With this arrangement, the first passage 11 and the second passage 12 can make full use of the space on the main body 1. The thermostat 2 is arranged at the end of the main body 1. When the main body 1 is connected to the engine housing 4, it is convenient for the thermostat 2 to keep a certain distance from the engine housing 4, ensuring that the thermostat 2 can work properly.

[0066] Specifically, the thermostat 2 can be arranged horizontally with the main body 1, and the thermostat 2, the first channel 11 and the second channel 12 are arranged horizontally; the main body 1 can be selected as a plate structure, the main body 1 extends horizontally, the thermostat 2 is at one end of the main body 1 in the horizontal direction, and the first channel 11, the second channel 12, the first pipeline 21, the second pipeline 22 and the third pipeline 23 are located below the exhaust pipe 3 of the thermostat 2 in the vertical direction, so that after the coolant enters the thermostat 2 through the first channel 11, the first pipeline 21 and the second pipeline 22, the gas in the coolant in the pipeline module can be discharged concentratedly through the exhaust pipe 3.

[0067] Referring to Figure 1 and Figure 2 As shown, in some embodiments, the first pipeline 21 extends in the direction of the thermostat 2 towards the second channel 12, and a support frame is provided on the main body 1, and the first pipeline 21 is lap-connected with the support frame. With such an arrangement, the support frame can support the extended first pipeline 21 and improve the stability of the first pipeline 21 in the pipeline module.

[0068] Specifically, the thermostat 2 and the second channel 12 can be arranged horizontally at both ends of the main body 1, the first pipeline 21 extends horizontally towards the second channel 12, and a support frame can be selected to be arranged at one end of the main body 1 away from the thermostat 2. Of course, the support frame can also be selected to be arranged between the second channel 12 and the thermostat 2, and the support frame is arranged below the first pipeline 21 so that the first pipeline 21 can be lapped on the support frame.

[0069] Referring to Figures 1 to 3 As shown, the embodiments of the present disclosure also provide a vehicle, including an engine housing 4, a heating system 8, a supercharger 7, a radiator 5, a water pump 6 and the pipeline module as described in any one of the above; a cooling cavity is provided inside the engine housing 4, and a first water jacket port and a second water jacket port communicating with the cooling cavity are provided on the engine housing 4, the first water jacket port communicates with the first channel 11, and the second water jacket port communicates with the second channel 12; the water pump 6 is connected in series with the radiator 5, the thermostat 2 is respectively connected with the radiator 5 and the water pump 6, the heating system 8 is connected with the first pipeline 21 and the second pipeline 22, and the supercharger 7 is connected with the first pipeline 21 and the third pipeline 23.

[0070] Specifically, a radiator 5 and a water pump 6 are also provided in the vehicle, the radiator 5 is connected in series with the water pump 6, and the thermostat 2 is respectively connected with the radiator 5 and the water pump 6, so that the thermostat 2 can control the switching of the coolant water circuit between the large cycle and the small cycle.

[0071] A cooling cavity is formed inside the above-mentioned engine housing 4. When the coolant flows through the cooling cavity, the coolant can absorb the heat generated when the engine housing 4 operates, thereby enabling the coolant to reduce the temperature of the engine. The first water jacket port provided on the engine housing 4 is communicated with the first passage 11, and the second water jacket port is communicated with the second passage 12. The coolant enters the second passage 12 from the water pump 6 and then flows into the cooling cavity through the second water jacket port. The coolant in the cooling cavity flows into the first passage 11 through the first water jacket port and then flows into the thermostat 2. The heating system 8 is communicated with the first pipeline 21 and the second pipeline 22, so that the coolant flowing into the thermostat 2 flows into the heating system 8 from the second pipeline 22, and then the coolant flows back to the thermostat 2 from the heating system 8 through the first pipeline 21. When the coolant flows into the second passage 12, it flows into the supercharger 7 through the third pipeline 23, and the coolant flows into the thermostat 2 from the supercharger 7 through the first pipeline 21.

[0072] When the coolant in the thermostat 2 is in the large circulation, it flows through the radiator 5 and the water pump 6 and into the second passage 12, so that the coolant circulates among the engine housing 4, the heating system 8, and the supercharger 7; when the coolant in the thermostat 2 is in the small circulation, it flows through the water pump 6 and into the second passage 12, so that the coolant circulates among the engine housing 4, the heating system 8, and the supercharger 7.

[0073] By using the pipeline module as described above, the engine housing 4, the heating system 8, and the supercharger 7 are interconnected, so that the coolant circulates among the engine housing 4, the heating system 8, and the supercharger 7 through the pipeline module. The exhaust pipe 3 provided on the thermostat 2 can discharge the gas in the pipeline structure formed by the pipeline module, avoiding the separate exhaust structures for the engine housing 4, the heating system 8, and the supercharger 7, simplifying the pipeline structure of the engine and its peripheral components, and improving the operation convenience of installing the engine housing 4, the heating system 8, and the supercharger 7 by using the pipeline module.

[0074] When the pipeline module and the vehicle provided by the embodiment of the present disclosure are specifically used, the fitting surface 13 of the main body portion 1 is fitted and connected with the engine housing 4. The first water jacket port includes a cylinder head port and a cylinder block port. The first water outlet 111 is communicated with the cylinder block port, and the second water outlet 112 is communicated with the cylinder head port. The engine water inlet 121 is communicated with the second water jacket port. The first opening of the thermostat 2 is communicated with the first passage 11, the second opening 24 and the third opening 25 are respectively communicated with the water pump 6 and the radiator 5, and the radiator 5 and the water pump 6 are connected in series. The heating system drain pipe 211 of the first pipeline 21 is communicated with the heating system 8, the supercharger drain pipe 212 of the first pipeline 21 is communicated with the supercharger 7, the third pipeline 23 is communicated with the supercharger 7, and the exhaust pipe 3 is communicated with the top side of the thermostat 2.

[0075] When the thermostat 2 is in the large circulation state, the first cavity and the second cavity of the thermostat 2 are connected. The coolant enters the cooling cavity of the engine housing 4 from the second passage 12 through the radiator 5 and the water pump 6. When the coolant passes through the second passage 12, it flows into the supercharger 7 through the third pipeline 23 to cool the supercharger 7. The coolant that has completed cooling the supercharger 7 flows into the heater system drain pipe 211 through the supercharger drain pipe 212, and then the coolant in the heater system drain pipe 211 flows into the thermostat 2; the coolant in the cooling cavity absorbs the heat of the engine housing 4, and the temperature of the coolant rises due to absorbing the heat of the engine housing 4. The coolant with the increased temperature flows into the thermostat 2 through the first passage 11. The coolant with a higher temperature flowing into the thermostat 2 flows into the heater system 8 through the second pipeline 22, and the coolant passing through the heater system 8 flows back to the thermostat 2 through the heater system drain pipe 211; the coolant flowing into the thermostat 2 all flows into the radiator 5 for cooling and then flows into the water pump 6, and all the coolant received by the water pump 6 flows into the cooling cavity of the engine housing 4 through the second passage 12.

[0076] When the thermostat 2 is in the small circulation state, the first cavity and the second cavity of the thermostat 2 are separated from each other. The coolant enters the cooling cavity of the engine housing 4 from the second passage 12 through the water pump 6. When the coolant passes through the second passage 12, it flows into the supercharger 7 through the third pipeline 23. The coolant in the supercharger 7 flows into the heater system drain pipe 211 through the supercharger drain pipe 212, and then the coolant in the heater system drain pipe 211 flows into the thermostat 2; the coolant in the cooling cavity flows into the thermostat 2 through the first passage 11. The coolant flowing into the thermostat 2 flows into the heater system 8 through the second pipeline 22, and the coolant passing through the heater system 8 flows back to the thermostat 2 through the heater system drain pipe 211; the coolant flowing into the thermostat 2 all flows into the water pump 6, and all the coolant received by the water pump 6 flows into the cooling cavity of the engine housing 4 through the second passage 12.

[0077] The gas in the coolant flowing into either the first cavity or the second cavity of the thermostat 2 moves upward and is discharged from the thermostat 2 through the exhaust pipe 3.
