Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of engine manufacturing, in particular to a supercharger backwater pipeline integrated with degassing function. BACKGROUND

[0002] The efficient operation of the cooling system is the key link to guarantee the performance and service life of the engine. Since air is mixed into the cooling liquid in the circulation process due to factors such as temperature change and component wear, air blockage phenomenon is formed, which leads to a decrease in local heat dissipation efficiency or even damage of components due to overheating. Therefore, the degassing design becomes an important part of the cooling system. The traditional engine usually sets a degassing port in the high position area such as the cylinder head, radiator or water pump, and uses the characteristic that the gas density is lower than that of the cooling liquid to discharge the accumulated air through gravity or circulating flow. This design has formed a mature scheme in the conventional engine body water route layout and can meet the degassing requirements under most working conditions. With the increasing stringency of emission regulations and the improvement of engine power density, the water-cooled supercharger, as a core component to improve the reliability of the whole machine and improve the combustion efficiency, is increasingly widely used. The water-cooled supercharger is connected with the engine cooling system through parallel water route branches, and the engine cooling liquid is used to cool the intermediate body of the supercharger, thereby protecting the supercharger and improving the reliability of the components.

[0003] However, the installation position of the supercharger is usually higher than the highest position of the engine body water route, which causes the internal water route of the supercharger to form a "high blind area". The conventional engine degassing port is only designed for the body water route, and the installation height and pipeline direction cannot cover the highest position of the supercharger water route, so that the air in this area is difficult to discharge through the original degassing channel. When air accumulates in the supercharger water route, local air blockage is formed, which leads to a decrease in the flow of the cooling liquid, a decrease in the heat dissipation efficiency of the supercharger, and further causes problems such as a decrease in supercharging efficiency and overheating of bearings. In severe cases, it may cause damage to the supercharger.

In the absence of explicit evidence that the above content has been disclosed on the filing date of the present patent application, the above background art should not be used to evaluate the novelty and inventiveness of the present application. UTILITY MODEL CONTENT

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to specific embodiments and the accompanying drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope and application of the present invention.

[0023] Non-limiting and non-exclusive embodiments will be described with reference to the following figures, wherein the same reference numerals denote the same parts unless otherwise specifically stated.

[0024] A booster return water pipeline with integrated degassing function, such as Figures 1-4 As shown, it is disposed between the engine water outlet seat 01 and the water-cooled turbocharger 02. The engine water outlet seat 01 and the water-cooled turbocharger 02 are respectively provided with an engine water passage degassing port 011 and a turbocharger water passage degassing port 021. The turbocharger water passage degassing port 021 is higher than the engine water passage degassing port 011. Specifically, the turbocharger return water pipeline of this application includes a first pipeline 03 and a second pipeline 04. The right end of the first pipeline 03 is connected to the engine water passage degassing port 01. 1. Connected, with the left end inclined to the upper left; the left end of the second pipeline 04 is connected to the water degassing port 021 of the booster, and the right end is inclined to the upper right; the left end of the first pipeline 03 and the right end of the second pipeline 04 are connected together by a T-shaped tee connector 05, and the T-shaped tee connector 05 is externally connected to a third pipeline 06 facing upward. The upper end of the third pipeline 06 is open, and the upper port of the third pipeline 06 is the water degassing port integrating the first pipeline 03 and the second pipeline 04.

[0025] The aforementioned turbocharger return water pipeline is constructed by setting up a first pipeline 03 and a second pipeline 04, connected by a T-shaped tee connector 05. A third pipeline 06 is installed upwards at the T-shaped tee connector 05, creating a high-level degassing structure. This structure caters to the characteristic that the turbocharger water circuit is higher than the engine water circuit, solving the problem of gas accumulation in the "high-level blind zone" of the turbocharger water circuit. Gas in the turbocharger water circuit and the engine water circuit can rise smoothly along the inclined first pipeline 03 and second pipeline 04 respectively, and after being collected by the T-shaped tee connector 05, it is efficiently discharged from the upper port of the third pipeline 06. Compared with traditional degassing... The gas degassing solution greatly improves degassing efficiency and effectively avoids gas resistance. The turbocharger return water pipeline has a compact design and simple connection methods, eliminating the need for large-scale modifications to the engine cooling system. While ensuring efficient degassing, it reduces installation difficulty and cost, facilitating rapid promotion and application in actual production. This turbocharger return water pipeline is compatible with various engine models and water-cooled turbochargers. Whether it is a newly developed engine cooling system or an upgrade of an existing system, it can be well integrated to meet the degassing requirements under different operating conditions, demonstrating broad application prospects.

[0026] In some examples of this embodiment, such as Figure 1As shown, a horizontal pipe 07 is horizontally arranged at the left end of the first pipe 03 and the right end of the second pipe 04. The T-shaped tee connector 05 is located at the junction of the two horizontal pipes 07. Specifically, the horizontal pipes 07 can be integrally formed with the corresponding first pipe 03 and second pipe 04, that is, the horizontal pipe 07 at the left end of the first pipe 03 is part of the first pipe 03, and the horizontal pipe 07 at the right end of the second pipe 04 is part of the second pipe 04. This makes it easier to position and fix the T-shaped tee connector 05 at the horizontal pipe 07 during installation, reducing assembly difficulty, improving production efficiency, and helping to reduce production costs. The gas discharged from the engine water circuit and the turbocharger water circuit first flows stably through the horizontal pipe 07 and then converges through the T-shaped tee connector 05. Compared with directly tilting the connection to the tee, the horizontal pipe 07 effectively avoids turbulence caused by sudden angle changes in gas flow, allowing the gas to converge more smoothly and orderly to the third pipe 06 for discharge, further improving the degassing efficiency.

[0027] In other examples of this example, such as Figure 1 As shown, a fixing clamp 08 is installed at the horizontal pipe 07. One end of the fixing clamp 08 clamps the horizontal pipe 07, and the other end is fixed to the cylinder head 09. The horizontal pipe 07 serves as the connection base for the T-shaped tee connector 05. Gas flows within it, and combined with engine vibration, this can cause severe shaking at the horizontal pipe 07. The fixing clamp 08 prevents the T-shaped tee connector 05 from shifting due to vibration. In this embodiment, the fixing clamp 08 is installed at the left end of the horizontal pipe 07 of the first pipe 03. In other examples, the fixing clamp 08 can also be installed at the right end of the horizontal pipe 07 of the second pipe 04; the specific installation is not limited, as long as it provides a stabilizing clamping effect. Specifically, as shown... Figure 1 , 3 As shown in Figure 4, the fixing clamp 08 includes a first clamping body 081 and a second clamping body 082. The upper end of the first clamping body 081 is an arc-shaped groove 0811 that matches the first pipe 03. The second clamping body 082 is disposed at the opening of the arc-shaped groove 0811 and is fixed by bolts, so that the first clamping body 081 and the second clamping body 082 cooperate to form a first space to accommodate the first pipe 03. Specifically, as shown in Figure 4... Figures 1-4 As shown, a rubber pad 10 is provided around the first pipe 03 passing through the first space. The fixing pipe clamp is clamped on the outside of the rubber pad 10. This structure makes the fixing pipe clamp 08 firmly clamped. When the engine is working, there may be shaking. This prevents the turbocharger return water pipe from shaking or even coming out of the engine water degassing port 011 and the turbocharger water degassing port 021, which would affect the overall exhaust.

[0028] In other examples of this embodiment, such as Figure 1As shown, the first pipeline 03 is divided into a left end pipe 031, a middle pipe 032, and a right end pipe 033. The left end pipe 031 and the right end pipe 033 are rigid pipes, while the middle pipe 032 is a braided flexible hose. The various parts can be connected together by welding. In the complex three-dimensional spatial layout of the engine compartment, the turbocharger return water pipeline needs to precisely align with multiple parts on different planes, such as the engine outlet seat 01 and the T-type tee connector 05. Due to the unavoidable tolerances in the manufacturing process of each part, traditional rigid pipelines are prone to problems such as interface misalignment and stress concentration. The braided flexible hose in the middle can achieve displacement compensation and appropriate angle adjustment. This eliminates the need for excessively demanding high-precision fits between parts during pipeline installation. Even with large accumulated tolerances, easy alignment can be achieved through the adaptive deformation of the braided flexible hose, significantly reducing assembly difficulty, increasing assembly success rate, significantly shortening assembly time, and improving production efficiency. The braided hose in the middle absorbs vibration energy through its own elastic deformation, reducing the transmission of vibration to the two end interfaces, preventing fatigue cracks caused by stress concentration at the interfaces, and effectively extending the overall service life of the pipeline.
