Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automobile manufacturing technology, specifically relating to a cooling water pipe for an automobile engine. Background Technology
[0002] The coolant hoses of a car engine are mainly used to connect the engine's cooling system to the water tank. Their main purpose is to pump the coolant from the engine water pump to the cylinder block reservoir, then circulate it to the water tank, where the water tank fan cools it at high speed, and then circulates it back to the engine. This is responsible for circulating the coolant to help the engine maintain a suitable operating temperature and prevent engine damage due to overheating, which could lead to vehicle breakdowns in severe cases.
[0003] The existing engine coolant hoses are designed in a straight line. When coolant flows in the coolant hoses, the coolant with a higher temperature inside the engine flows from the engine into the coolant hoses. However, the coolant entering the coolant hoses cannot effectively dissipate heat, resulting in the coolant entering the engine from the coolant hoses being at a high temperature. This situation causes the coolant inside the coolant hoses to not be cooled effectively, which in turn prevents the engine temperature from being reduced effectively. Consequently, the engine temperature becomes too high, affecting the overall performance of the vehicle. Utility Model Content
[0004] The purpose of this invention is to provide a cooling water pipe for an automobile engine to solve the above-mentioned problems.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling water pipe for an automobile engine, comprising an inlet pipe, one end of which is connected to an inlet pipe connecting sleeve, and a sealing ring is provided inside the inlet pipe connecting sleeve; the end of the inlet pipe connecting sleeve away from the inlet pipe is connected to the engine cooling system; the other end of the inlet pipe is connected to a transition pipe, and the inlet pipe and the transition pipe are fixedly connected; the end of the transition pipe away from the inlet pipe is fixedly connected to an outlet pipe, and the transition pipe and the outlet pipe are fixedly connected; the end of the outlet pipe away from the transition pipe is connected to an outlet pipe connecting sleeve, and the outlet pipe connecting sleeve is provided with the same sealing ring as the inlet pipe connecting sleeve; a buffer mechanism is provided inside the inlet pipe; when cooling water moves from inside the engine into the inlet pipe, the cooling water pushes the buffer mechanism to rotate, and the buffer mechanism reduces the flow velocity of the cooling water when it enters the inlet pipe, thereby reducing the speed of the cooling water and preventing the cooling water from entering the inlet pipe too quickly.
[0006] Preferably, the transition pipe between the inlet pipe and the outlet pipe is arranged in a curved manner, and a spiral channel is opened inside the transition pipe, and the spiral channel is arranged to fit the inner wall of the spiral pipe.
[0007] Preferably, the buffer mechanism includes a fixed plate, a rotating plate, and buffer blades. An upper connecting column and a lower connecting column are provided at the connection between the water inlet pipe and the water inlet pipe sleeve, and both the upper and lower connecting columns are located inside the water inlet pipe. A fixed plate is rotatably mounted on the upper connecting column, and a rotating plate is rotatably mounted on the lower connecting column. A flow-slowing blade is provided between the fixed plate and the rotating plate.
[0008] Preferably, multiple flow-slowing blades are provided, and the flow-slowing blades are arranged in a ring array between the fixed plate and the rotating plate, and the overall shape of the flow-slowing blades is an arc-shaped structure.
[0009] Preferably, a spray pipe is provided near the water outlet pipe connecting sleeve of the water outlet pipe, one end of the spray pipe is connected to the water outlet pipe connecting sleeve, and the other end of the spray pipe is connected to the water outlet pipe.
[0010] Preferably, the nozzle is fitted to the inner wall of the water outlet pipe, and the diameter of the middle part of the nozzle is smaller than the diameter of both ends of the nozzle.
[0011] The technical effects and advantages of this utility model are as follows: During use, when the cooling water inside the engine enters the inlet pipe through the inlet pipe connecting sleeve, the high-temperature cooling water pushes the buffer mechanism, thereby reducing the flow speed of the cooling water. This prevents the cooling water from flowing too fast, which would prevent it from effectively reducing the temperature and thus the internal temperature of the engine. At the same time, reducing the flow speed of the cooling water can prevent insufficient flow of cooling water in some areas, which would lead to uneven engine temperature distribution. When the cooling water enters the transition pipe after passing through the buffer mechanism, the special shape of the transition pipe can increase the flow path of the cooling water, thereby more effectively reducing the temperature of the cooling water and thus better cooling the engine. When the cooling water enters the engine through the nozzle set in the outlet pipe, the cooling water accelerates its flow speed through the nozzle, which allows the cooled coolant to quickly pass through the engine, enabling more uniform heat dissipation and ensuring that the temperature of all parts of the engine is consistent. At the same time, it can prevent impurities in the cooling water from accumulating inside the engine, thereby ensuring the cleanliness of the overall cooling system. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] This utility model provides a cooling water pipe for an automobile engine, as shown in the figure. It includes an inlet pipe, one end of which is connected to an inlet pipe connecting sleeve 1, which contains a sealing ring. The end of the inlet pipe connecting sleeve 1 away from the inlet pipe 2 is connected to the engine cooling system. The other end of the inlet pipe 2 is connected to a transition pipe 3, and the inlet pipe 2 and transition pipe 3 are fixedly connected. The end of the transition pipe 3 away from the inlet pipe 2 is fixedly connected to an outlet pipe 4, and the transition pipe 3 and outlet pipe 4 are fixedly connected. The end of the outlet pipe 4 away from the transition pipe 3 is connected to an outlet pipe connecting sleeve 5, which contains the same sealing ring as the one in the inlet pipe connecting sleeve 1. A buffer mechanism 23 is provided inside the inlet pipe 2. When cooling water moves from inside the engine into the inlet pipe 2, the cooling water pushes the buffer mechanism 23 to rotate, reducing the flow speed of the cooling water entering the inlet pipe 2, thereby reducing the speed of the cooling water and preventing it from entering the inlet pipe 2 too quickly.
[0021] Specifically, the transition pipe 3 between the inlet pipe 2 and the outlet pipe 4 is arranged in a curved manner. The transition pipe 3 has a spiral channel 31 inside, and the spiral channel 31 is set to fit the inner wall of the spiral pipe.
[0022] Specifically, the buffer mechanism 23 includes a fixed plate 231, a rotating plate 232, and buffer blades. An upper connecting column 21 and a lower connecting column 22 are provided at the water inlet pipe 2 and the water inlet pipe connecting sleeve 1, and both the upper connecting column 21 and the lower connecting column 22 are located inside the water inlet pipe 2. The fixed plate 231 is rotatably mounted on the upper connecting column 21, and the rotating plate 232 is rotatably mounted on the lower connecting column 22. A flow-slowing blade 233 is provided between the fixed plate 231 and the rotating plate 232.
[0023] Specifically, multiple flow-slowing blades 233 are provided, and the flow-slowing blades 233 are arranged in a ring array between the fixed plate 231 and the rotating plate 232. The overall shape of the flow-slowing blades 233 is an arc-shaped structure 234.
[0024] Specifically, a spray pipe 41 is provided near the water outlet pipe connecting sleeve 5 on the water outlet pipe 4. One end of the spray pipe 41 is connected to the water outlet pipe connecting sleeve 5, and the other end of the spray pipe 41 is connected to the water outlet pipe 4.
[0025] Specifically, the nozzle 41 is fitted to the inner wall of the water outlet pipe 4, and the diameter of the middle part of the nozzle 41 is smaller than the diameter of the two ends of the nozzle 41.
[0026] Working Principle: When using this invention, the inlet pipe connecting sleeve 1 is connected to the engine outlet pipe 4, and the outlet pipe connecting sleeve 5 is connected to the engine inlet pipe 2. When the cooling water enters the transition pipe 3 through the buffer mechanism 23 inside the inlet pipe 2, the cooling water pushes multiple flow-slowing blades 233. These blades rotate between the upper connecting post 21 and the lower connecting post 22 via the upper and lower fixed plates 231 and rotating plate 232. When the cooling water enters the inlet pipe 2, it pushes the flow-slowing blades 233 to rotate. During rotation, the flow-slowing blades 233 effectively reduce the flow velocity of the cooling water, preventing excessive flow velocity. The cooling water's heat dissipation effect is about to decrease. When the cooling water enters the transition pipe 3, the curved design of the transition pipe 3 increases its flow path, which can effectively reduce the temperature of the cooling water in the transition pipe 3. At the same time, the spiral channel 31 in the transition pipe 3 can also increase the flow path of the cooling water. When the cooling water flows through the transition pipe 3 to the outlet pipe 4, the nozzle 41 in the outlet pipe 4 can make the cooling water first flow through the larger diameter pipe, then be compressed in the middle of the nozzle 41, and finally be released through the rear end of the nozzle 41. This compression and release of the cooling water increases the flow speed of the cooling water, allowing it to flow through the engine interior more quickly and further reduce the internal temperature of the engine.
[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
