Description

Technical Field

[0001] This utility model relates to the field of air conditioning pipe technology, and in particular to a coaxial pipe bulge structure for automotive air conditioning pipes. Background Technology

[0002] Automotive air conditioning piping is a crucial carrier for transporting refrigerant, coolant, and other fluid media in an automotive air conditioning system. It primarily connects core functional components such as the compressor, condenser, evaporator, and expansion valve. Through a closed piping system, it establishes a fluid circulation path, ensuring the refrigerant completes a thermodynamic cycle of "compression-condensation-throttling-evaporation" within the system. This, in turn, cools, heats, or dehumidifies the air inside the vehicle, directly determining the cooling / heating efficiency and passenger comfort. Furthermore, it must meet performance requirements such as high pressure resistance, vibration resistance, corrosion resistance, and leak prevention to adapt to the complex operating conditions of a vehicle while in motion.

[0003] However, the existing adapter structures for different diameter pipes in automotive air conditioning systems have many drawbacks: On the one hand, traditional adapters mostly rely on clamps, flanges, or threaded connections, requiring auxiliary accessories such as bolts and clamps. This not only makes the installation process cumbersome and inefficient, but also makes the sealing performance susceptible to the influence of assembly precision. If the sealing surfaces are not tightly fitted, refrigerant leakage can easily occur, reducing air conditioning efficiency and wasting the medium. On the other hand, traditional adapters have a single function, only enabling simple pipe diameter conversion. They are difficult to integrate branch pipe functions and require additional tee fittings, resulting in complex pipe layouts, large space occupation, and insufficient connection strength between the adapter and the pipe. Long-term exposure to vehicle vibrations can easily lead to loosening and detachment, increasing the frequency and cost of fault repair. Utility Model Content

[0004] The purpose of this utility model is to provide a coaxial tube bulge structure for automotive air conditioning pipes, which solves the problem that traditional adapters in the prior art mostly rely on clamps, flanges or threaded connections, and require auxiliary accessories such as bolts and clamps, which not only makes the installation process cumbersome but also results in low assembly efficiency.

[0005] To achieve the above objectives, a coaxial tube bulge structure for an automotive air conditioning pipe is provided, including an air conditioning pipe 2, one end of which is fixedly connected to a bulge component, and an mounting hole 1 is provided on the inner side of the bulge component, the mounting hole 1 being matched with the diameter of the air conditioning pipe 2.

[0006] The other end of the inner side of the bulge is provided with a second mounting hole. An air conditioning pipe is installed inside the second mounting hole, and the end of the air conditioning pipe corresponding to the second mounting hole is sleeved on the second air conditioning pipe.

[0007] According to the coaxial tube bulge structure of the automotive air conditioning pipe, the diameter of the first air conditioning pipe is larger than that of the second air conditioning pipe, and the first air conditioning pipe can be fitted onto the outer end of the second air conditioning pipe.

[0008] According to the coaxial tube bulge structure of an automotive air conditioning pipe, a branch tube is provided through the top of the bulge.

[0009] According to the coaxial tube bulge structure of an automotive air conditioning pipe, a branch tube is provided through the bottom of the bulge.

[0010] The above-mentioned solution has the following beneficial effects:

[0011] This patent adopts an integrated design of the bulge component and the air conditioning pipe 2. The air conditioning pipe 1 is directly sleeved on the outside of the pipe 2 and locked by the bulge component, which eliminates the traditional connection method such as clamps, simplifies installation, saves time and effort and reduces costs. At the same time, the bulge component integrates the top branch pipe 2 and the bottom branch pipe 1 to realize the tee function, improve the pipe adaptability, and enhance the connection stability and sealing performance, reducing leakage and failure maintenance frequency.
