Description

Technical Field

[0001] This utility model relates to the field of injection molded pipes, and in particular to a water auxiliary pipe assembly for an automotive engine cooling system. Background Technology

[0002] The cooling system of a car engine removes 20% to 30% of the total heat released by the fuel. On the one hand, if the engine cooling system removes too much heat, the engine will become too cold, leading to unstable combustion, slow combustion, reduced power, and increased fuel consumption. It will also increase the viscosity of the lubricating oil, causing poor lubrication and accelerated wear of parts. On the other hand, if the engine cooling system removes too little heat, it will cause the engine to overheat, resulting in pre-ignition, knocking, and piston crown erosion in gasoline engines. Therefore, accurately controlling the coolant temperature and rationally distributing the coolant to remove heat is crucial.

[0003] Engine cooling systems typically use temperature sensors to detect the temperature of the water flowing into the system. Existing engine cooling systems generally include a three-way valve, usually made of plastic, with three ports connecting to the radiator outlet, engine inlet, and transmission inlet. The temperature sensor is located on the radiator inlet side to detect the temperature of the water entering the radiator. With the continuous development of automobiles, to improve the cooling performance of engine cooling systems, more and more models are beginning to install temperature sensors on the radiator outlet side to detect the radiator outlet temperature. However, since the radiator outlet pipe is generally made of pure rubber, it is unsuitable for installing a temperature sensor. A plastic connector must be used between the radiator outlet and the engine inlet to install the temperature sensor. This not only increases the sealing interface of the engine cooling system, increasing the risk of leakage, but also increases the assembly difficulty of the temperature sensor and occupies more installation space. Therefore, we provide a pipe fitting assembly for automotive engine cooling systems to improve the convenience of installing a temperature sensor at the radiator outlet.

[0004] The water auxiliary piping assembly is a common component in the engine cooling system of a car engine. The coolant pipes are often fixed inside the engine by brackets welded to their exterior. However, due to the irregular shape of the coolant pipes, the brackets welded to their exterior can be difficult to install. If the welding position is not very precise, the coolant pipes cannot be installed smoothly. Furthermore, during use, the structural design of the fixed assembly of the water auxiliary piping assembly of the car engine cooling system makes the main pipe section of the assembly prone to loosening during bumpy rides, affecting the use of water cooling. Utility Model Content

[0005] The purpose of this utility model is to provide a water auxiliary pipe assembly for an automotive engine cooling system, which solves the problems of unstable connection and loose assembly connection between the pipe bodies in ordinary automotive engine cooling systems.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a water auxiliary pipe assembly for an automotive engine cooling system, including a cooling connecting pipe body and a pipe assembly fixing assembly located at the outer end of the cooling connecting pipe body. The cooling connecting pipe body includes a main pipe body structure and a branch pipe body structure. The main pipe body structure includes a main pipe connection joint and branch inlet pipe joints located on both sides of the main pipe connection joint. The branch pipe body structure includes a branch inlet pipe body connected to the branch inlet pipe joint and an inner return bend pipe body structure. The pipe assembly fixing assembly includes a return bend outer side fixing assembly located on the upper part of the inner return bend pipe body structure, an inlet pipe fixing assembly located on the outer side of the branch inlet pipe body, and an installation kit fixing component located on the branch inlet pipe body.

[0007] The main pipeline connection connector is a tee or cross connector.

[0008] The outer side fixing assembly of the return bend includes an outer side connector and an inner side connector, which are integrally injection molded with the branch lead pipe body.

[0009] The aforementioned pipe fixing assembly includes a connecting side support seat located on the outside of the branch pipe body and a mounting locking seat located on the outside of the connecting side support seat. The pipe fixing assembly and the branch pipe body are integrally injection molded.

[0010] The installation kit fixing assembly includes a connecting outer sleeve that snaps into and matches the diameter of the branch lead pipe body, and a tightening inner sliding sleeve provided in the connecting outer sleeve. A tightening inner locking pressure block is provided on the outside of the tightening inner sliding sleeve, and an end locking pressure block is provided on the outside of the connecting outer sleeve. A connecting cable is provided between the end locking pressure block and the tightening inner locking pressure block.

[0011] The beneficial effects of this utility model are as follows: By setting the docking structure of each branch pipe of the assembly, this utility model facilitates the connection of the connecting pipes to the liquid cooling system pipes, thereby promoting quick installation of pipe joints. This meets the cooling requirements of the new fuel engine, reduces the energy consumption of the cooling system on the engine, and thus improves the thermal conversion efficiency of the new engine, reducing emissions. By setting the pipe assembly fixing component group of the assembly, the stability of the assembly assembly is facilitated, and the engine fixing thread hole positions are securely installed, reducing the impact of machining errors on installation and increasing its practical performance. Furthermore, this design has the advantages of simple structure, ease of manufacture, and high efficiency.
