Description

Technical Field

[0001] This utility model belongs to the field of cooling pipeline technology, and in particular relates to a pipeline assembly with exhaust pressure regulation function. Background Technology

[0002] With the development of modern vehicle technologies such as new energy vehicles and high-end fuel vehicles, their thermal management systems (usually referring to cooling systems) are becoming increasingly complex and sophisticated. This system is responsible for the precise temperature control of key components such as batteries, motors, electronic control units (collectively known as the "three-electric system"), and engines. The reliability of its operation is directly related to the performance, safety, and lifespan of the entire vehicle.

[0003] During routine maintenance of a vehicle's thermal management system, such as adding coolant or replacing components like the radiator, water pump, or heater, air inevitably gets into the piping. This trapped air can lead to a series of serious problems. 1. Air lock formation: Air accumulates at the highest point or narrowest part of the pipe, forming an "air lock" that hinders the normal circulation of coolant, resulting in insufficient local flow.

[0004] 2. Causes overheating: Due to poor coolant circulation, heat cannot be effectively dissipated, which can easily lead to local overheating of the battery, motor, and electronic control system. This can result in either limited power operation of the system or serious safety accidents such as thermal runaway.

[0005] 3. Abnormal noise and corrosion: The air in the pipeline will produce vibration and abnormal noise under the drive of the pump. At the same time, the oxygen in the air will accelerate the deterioration of the coolant and the oxidation and corrosion of the metal parts inside the system.

[0006] Currently, the most common method used in the industry is to open the expansion tank cap to release air. The specific operating procedure is as follows: open the tank cap, fill it with coolant, start the engine, wait for the engine to run until it is warm, observe the liquid level in the tank drop and bubbles emerge until water flows out, and then tighten the cap.

[0007] This method has the following inherent drawbacks: 1. Incomplete venting: This method relies on the natural circulation of coolant to push the gas to the top of the reservoir for venting. For systems with complex piping and local high points, the gas is very likely to stagnate in these dead corners, making it impossible to ensure complete venting.

[0008] 2. The operation process is cumbersome and time-consuming: The entire process requires starting, shutting down, observing and replenishing coolant, which takes a long time, greatly reduces maintenance efficiency and increases labor costs.

[0009] 3. Coolant waste and environmental pollution: During the exhaust process, high-temperature coolant often splashes out of the reservoir along with the gas, resulting in waste and posing a risk of burns. The splashed coolant also pollutes the environment.

[0010] 4. Unable to actively regulate pressure: This method is completely incapable of manually relieving pressure when the system pressure is abnormal, lacking an additional safety barrier.

[0011] Therefore, there is an urgent need in this field for a new pipeline structure that can achieve rapid, thorough, and controllable exhaust while also taking into account the system pressure regulation function, in order to overcome the fundamental shortcomings of the existing technology. Summary of the Invention

[0012] The purpose of this utility model is to provide a pipeline assembly with exhaust pressure regulation function. By setting an exhaust structure that can be manually switched at the joint, the pressure can be adjusted at the exhaust joint to discharge the gas in the system. This can keep the pressure in the entire pipeline system within a certain range, ensuring smooth circulation of coolant. The whole process is simple and quick to operate, shortening the original exhaust process to be completed in a very short time, greatly improving maintenance efficiency and saving labor and time costs.

[0013] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a pipeline assembly with exhaust pressure regulation function, including a pipeline body, and a first connector and a second connector are respectively provided at both ends of the pipeline body; The first connector includes a connector body and an exhaust plug; The connector body is integrally connected to a 90° elbow structure pipe section at its tail end. The pipe section is integrally provided with a sleeve structure end pipe in the area away from the connector body. The inner wall of the end pipe is provided with internal threads, and the inner side of the outer end of the end pipe is provided with an inner step portion. The exhaust plug is a T-shaped rod. The small-diameter section of the exhaust plug has external threads on its circumferential side. The small-diameter section of the exhaust plug is threaded inside the end tube. The large-diameter section of the exhaust plug covers the end face of the end tube. A sealing ring is provided between the inner wall of the large-diameter section of the exhaust plug and the inner step portion. The small-diameter section of the exhaust plug has an exhaust groove along its length on its circumferential side.

[0014] Furthermore, the end of the connecting pipe section away from the connector body is integrally provided with a barbed pipe connector, which is interference-fitted into the inner end of the pipe body.

[0015] Furthermore, the large-diameter section of the exhaust plug is provided with a driving structure, which is an inner hole structure or an outer convex structure.

[0016] Furthermore, the driving structure of the inner hole structure is an internal hexagonal hole, a plum blossom hole, a cross hole, a slotted groove, a square hole, a triangular hole, or an irregularly shaped hole.

[0017] Furthermore, the driving structure of the convex structure is an external hexagonal head, a square head, a dodecagonal head, a knurled head, or a T-shaped handle head.

[0018] Furthermore, the sealing ring is an O-ring.

[0019] This utility model has the following beneficial effects: 1. This utility model, by setting a manually switchable exhaust structure at the joint, allows for pressure adjustment at the exhaust joint to expel gas from the system, maintaining the pressure within a certain range in the entire pipeline system, ensuring smooth coolant circulation. The entire process is simple and quick, shortening the original exhaust process to a very short time, greatly improving maintenance efficiency and saving labor and time costs.

[0020] 2. This utility model integrates an exhaust structure on the connector, which can be used as a manual safety valve under certain circumstances. When the system pressure rises abnormally due to a fault, maintenance personnel can slowly loosen the screw head to release pressure in a controlled manner, thereby avoiding more serious faults such as pipe bursts and kettle damage. It provides an additional passive safety protection measure, the exhaust valve, for the thermal management system, and improves the system's safety margin.

[0021] 3. By integrating the exhaust function mechanism and connector into a single design, this utility model reduces the number of additional connection points and parts, fundamentally lowering the risk of leakage. The assembly is compact, does not occupy extra space, and can be integrated as a standard module into the thermal management pipeline of any vehicle model, making it highly versatile.

[0022] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
