Description

Technical Field

[0001] The utility model belongs to the technical field of diesel engines, and particularly relates to a novel water-cooled intercooler and a cooling system. Background Art

[0002] With the rapid development of the modern automotive industry, diesel engines are widely used in various vehicle models due to their high thermal efficiency and excellent power performance. High-performance vehicles, in particular, require diesel engines to deliver higher power and torque, often achieved through turbocharging. However, the increased intake air temperature during turbocharging can lead to performance degradation and even cause adverse reactions such as detonation. Therefore, intercooling devices, which reduce diesel engine intake air temperature, are crucial.

[0003] Currently, intercoolers primarily come in two types: air-cooled and water-cooled. Air-cooled intercoolers have a simple structure, but relatively low heat dissipation efficiency, and their performance degrades significantly in high-temperature environments. Water-cooled intercoolers are typically installed at the front of the diesel engine compartment, working in conjunction with the radiator on the front side of the diesel engine. They utilize water treated by the radiator as a cooling medium. Water's high specific heat capacity effectively reduces the diesel engine's intake air temperature, improving its power performance and fuel economy. While existing water-cooled intercoolers have achieved some heat dissipation effectiveness, they are complex and take up a lot of space. In some high-performance vehicles, the limited space in the power compartment complicates the layout of components such as the intercooler, water pump, and piping, often hindering a systematic integrated design. Furthermore, configuring a high-performance intercooler within this limited space to accommodate the increased heat dissipation requirements is challenging.

[0004] Therefore, there is a need for a new type of water-cooled intercooler and cooling system that can achieve both integrated design and high performance matching. Utility Model Content

[0005] The purpose of this utility model 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, which can reserve a larger operating space for the entire vehicle layout.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A new type of water-cooled intercooler device includes a turbocharger arranged near the flywheel end of the 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 the drive gear inside the diesel engine; one end of the radiator located on the front side of the diesel engine is connected to the intercooler through the water pump and the water inlet pipe in sequence, and the other end is connected to the intercooler through the water outlet pipe.

[0008] A further improvement of the technical solution of the present utility model is that: a heat exchange mechanism is provided inside the intercooler, including an air path and a water path overlapping each other; the intercooler is provided with 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 the intercooler rear intake pipe 1 and the intercooler rear intake pipe 2 in sequence.

[0009] A further improvement of the technical solution of the present utility model 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.

[0010] A further improvement of the technical solution of the present utility model is that: the intercooler is respectively provided with a water inlet and a water outlet adapted to the water circuit on its front side wall, 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.

[0011] A cooling system includes a novel water-cooled intercooler.

[0012] Due to the adoption of the above technical solution, the technical progress achieved by the present invention is:

[0013] The utility model is a water-cooled intercooler and cooling system suitable for high-performance vehicles. It can realize integrated design and high-performance matching at the same time. It has high cooling efficiency, reasonable layout and compact structure, and can reserve more operating space for the layout of the whole vehicle. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention is further described in detail below with reference to the embodiments:

[0018] Example 1

[0019] like Figure 1 and Figure 2 As shown, this embodiment provides a new water-cooled intercooler device, including 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, and 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.

[0020] Specifically, a heat exchange mechanism is provided inside the intercooler 3, including an air path and a water path that overlap with each other. The intercooler 3 has an air inlet 10 and an air outlet 11 at both ends thereof that are adapted to the air path. The air inlet 10 is provided at the end of one end of the intercooler 3 and is connected to the turbocharger 5 through the 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 the intercooler rear intake pipe 1 and the intercooler rear intake pipe 2 2 in sequence, 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 path on its front side wall, wherein the water inlet 7 is arranged close to the air outlet 11 of the air path 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 air path and is connected to the radiator through the water outlet pipe 14.

[0021] During operation, the high-temperature exhaust gas discharged from the exhaust manifold of the diesel engine 13 is supercharged by the turbocharger 5 and then passes through the supercharged intake pipe 4 and the air inlet 10 in turn into the air path of the intercooler 3. 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 flows relative to the high-temperature gas after supercharging in the air path for heat exchange to cool it down. The cooled gas in the air 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. 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 treatment and cooling, thereby forming a circulating operation mode, which can simultaneously achieve integrated design and high-performance matching, with high cooling efficiency, reasonable layout and compact structure, and can reserve more operating space for vehicle layout.
