Description
Technical Field
[0001] The invention belongs to the technical field of diesel engines, and in particular relates to a novel water-cooled intercooler and a cooling system. Background Art
[0002] With the rapid development of the modern automobile industry, diesel engines are widely used in various models due to their high thermal efficiency and good power performance. Especially in high-performance models, diesel engines require higher power and torque output, which is often achieved through turbocharging technology. However, during the turbocharging process, the increase in the intake temperature of the diesel engine will lead to a decrease in its performance and may even cause undesirable phenomena such as deflagration. Therefore, the intercooler used to reduce the intake temperature of the diesel engine is very important.
[0003] At present, intercoolers mainly include air-cooled and water-cooled types. The air-cooled intercooler has a simple structure, but the heat dissipation efficiency is relatively low, and the performance drops significantly in high temperature environments. The water-cooled intercooler is usually installed at the front end of the diesel engine compartment, and cooperates with the radiator on the front side of the diesel engine. It uses water treated by the radiator as a cooling medium. Through the high specific heat capacity of water, it can more effectively reduce the intake temperature of the diesel engine and improve the power performance and fuel economy of the diesel engine. Although the existing water-cooled intercooler has achieved a certain heat dissipation effect, it has a complex structure and occupies a large space. In some high-performance models, due to the limited space in the power compartment of the whole vehicle, the layout of the intercooler, water pump, pipelines and other components is relatively complex, often subject to space constraints, and it is difficult to achieve a systematic integrated design. In addition, it is also difficult to configure a high-performance intercooler in a limited space to meet higher heat dissipation requirements.
[0004] Therefore, a new type of water-cooled intercooler and cooling system is needed that can achieve both integrated design and high performance matching. Summary of the invention
[0005] The purpose of the present invention is to provide a new type of water-cooled intercooler and cooling system, which is suitable for high-performance vehicles and can simultaneously achieve integrated design and high-performance matching. It has high cooling efficiency and a reasonable layout and compact structure, and can reserve a larger operating space for the entire vehicle layout.
[0006] To achieve the above purpose, the technical solution adopted by the present invention is: A novel water-cooled intercooler comprises a turbocharger arranged near the flywheel end of a diesel engine, an intercooler arranged on the top of the diesel engine through a bracket and connected to its intake manifold at one end and its exhaust manifold at the other end through the turbocharger, and a water pump arranged near the turbocharger and connected to a driving gear inside the diesel engine; one end of a radiator located on the front side of the diesel engine is connected to the intercooler through the water pump and a water inlet pipe in sequence, and the other end is connected to the intercooler through a water outlet pipe.
[0007] A further improvement of the technical solution of the present invention is that a heat exchange mechanism is arranged inside the intercooler, including an air path and a water path that overlap each other; the intercooler has an air inlet and an air outlet adapted to the air path at both ends thereof, the air inlet of the intercooler is connected to the turbocharger through a boost intake pipe, and the air outlet is connected to the intake manifold of the diesel engine through intercooler rear intake pipe 1 and intercooler rear intake pipe 2 in turn.
[0008] A further improvement of the technical solution of the present invention is that the air inlet is opened at the end of one end of the intercooler, and the air outlet is opened on the front side wall of the other end of the intercooler.
[0009] A further improvement of the technical solution of the present invention is that a water inlet and a water outlet adapted to the water circuit are respectively arranged on the front side wall of the intercooler, wherein the water inlet is arranged close to the air outlet of the gas circuit and is connected to the water pump through a water inlet pipe, and the water outlet is arranged close to the air inlet of the gas circuit and is connected to the radiator through a water outlet pipe.
[0010] A cooling system comprises a novel water-cooled intercooler.
[0011] Due to the adoption of the above technical solution, the technical progress achieved by the present invention is: The water-cooled intercooler and cooling system of the present invention are suitable for high-performance vehicles, and can realize integrated design and high-performance matching at the same time. While having high cooling efficiency, the layout is reasonable and the structure is compact, and a larger operating space can be reserved for the layout of the entire vehicle.

DETAILED DESCRIPTION
[0013] The present invention is further described in detail below in conjunction with embodiments: Example 1 like Figure 1 and Figure 2As shown, the present embodiment provides a novel water-cooled intercooler, comprising a turbocharger 5, an intercooler 3 and a water pump 6, wherein the turbocharger 5 is arranged near the flywheel end of the diesel engine 13, the intercooler 3 is arranged on the top of the diesel engine 13 through a bracket 12, and one end of the intercooler 3 is connected to the intake manifold of the diesel engine 13, and the other end thereof is connected to the exhaust manifold of the diesel engine 13 through the turbocharger 5, the water pump 6 is arranged near the turbocharger 5 and is connected to the driving gear inside the diesel engine 13, that is, the water pump 6 is connected to the driving gear of the diesel engine 13 through its water pump shaft, one end of the radiator located on the front side of the diesel engine 13 is connected to the intercooler 3 through the water pump 6 and the water inlet pipe 8 in sequence, and the other end thereof is connected to the intercooler 3 through the water outlet pipe 14.
[0014] Specifically, a heat exchange mechanism is provided inside the intercooler 3, including an air path and a water path that overlap each other. The intercooler 3 is provided with an air inlet 10 and an air outlet 11 adapted to the air path at both ends thereof, wherein the air inlet 10 is provided at the end of one end of the intercooler 3, and is connected to the turbocharger 5 through a boost intake pipe 4, and the air inlet 10 and the boost intake pipe 4 are connected by a flange; the air outlet 11 is provided on the front side wall of the other end of the intercooler 3, and is connected to the intake manifold of the diesel engine 13 through an intercooler rear intake pipe 1 and an intercooler rear intake pipe 2 in turn, and the air outlet 11 and the intercooler rear intake pipe 1 are connected by a flange. At the same time, the intercooler 3 is respectively provided with a water inlet 7 and a water outlet 9 adapted to the water circuit on its front side wall, wherein the water inlet 7 is arranged close to the air outlet 11 of the gas circuit and is connected to the water pump 6 through the water inlet pipe 8, and the water outlet 9 is arranged close to the air inlet 10 of the gas circuit and is connected to the radiator through the water outlet pipe 14.
[0015] During operation, the high-temperature exhaust gas discharged from the exhaust manifold of the diesel engine 13 is pressurized by the turbocharger 5 and then enters the gas path of the intercooler 3 through the supercharged intake pipe 4 and the air inlet 10 in turn. At the same time, the water pump 6 is directly driven by the driving gear inside the diesel engine 13 to draw the cooling water in the radiator into the water path of the intercooler 3 through the water inlet pipe 8 and the water inlet 7, and relatively flows with the high-temperature gas after the pressurization in the gas path to exchange heat to cool it down. The cooled gas in the gas path passes through the intercooler rear intake pipe 1 1, the intercooler rear intake pipe 2 2 and the intake pipe manifold in turn into the diesel engine 13 to participate in work, thereby increasing the output power of the engine, and the high-temperature water after heat exchange in the water path returns to the radiator through the water outlet 9 and the water outlet pipe 14 for processing and cooling, thereby forming a cyclic operation mode, which can simultaneously realize integrated design and high-performance matching, with high cooling efficiency, reasonable layout and compact structure, and can reserve more operating space for vehicle layout.
