Problems solved by technology

Due to factors such as space layout, the gas passing through the intake structure of the intercooler has uneven flow in the core of the intercooler, resulting in uneven heat transfer of high-temperature gas
Especially for air-cooled intercoolers, when there is uneven heat exchange in the core, condensed water is likely to be generated during the cooling process of high-temperature gas, which will increase the risk of freezing of the intercooler
Market research found that there are many intercooler freezing problems in cars in severe cold areas, which has a serious adverse impact on engine power and user use. At present, some insulation measures are added to the bend of the intercooler outlet pipe, which has failed. to effective effect

Embodiment 1

[0018] Embodiment 1: as Figure 1 to Figure 5 The intercooler of the automobile supercharged engine shown includes an air intake structure 2, a core body 3 and an air outlet structure 4. The core body 3 is arranged between the air intake structure 2 and the air outlet structure 4 and is connected to the air intake structure 2 and the air outlet structure. 4 are connected, the intake structure 2 includes an intake pipe 21, an intake chamber 22 and a deflector 23, the intake pipe 21 communicates with the intake chamber 22, a part of the deflector 23 is located in the intake pipe 21, and another part is located In the chamber 22, the inlet pipe 21, the air inlet chamber 22 and the deflector 23 are integrally formed by injection molding, and the material is high-temperature nylon. The deflector 23 is composed of an arc-shaped plate 232 , a vertical straight plate 231 connected to one end of the arc-shaped plate 232 , and a horizontal straight plate 233 connected to the other end o...

Embodiment 2

[0020] Embodiment 2: Most of the structure of the intercooler of the automobile supercharged engine in this embodiment is the same as Embodiment 1, the difference is that: the vertical straight plate 231 is positioned at the right side of the center line of the inlet pipe 21, and is connected with the inlet pipe. The distance between the centerlines of 21 is also 4mm, and the horizontal straight plate 233 is located on the lower side of the centerline of the air inlet chamber 22, and the distance between the centerline of the air inlet chamber 22 is also 4mm.

[0021] The thickness of deflector 23 in above-mentioned embodiment 1,2 also can be 1mm, 4mm, 5mm, the length of vertical straight plate 231 also can be 30mm, 50mm, the length of horizontal straight plate 233 also can be 40mm, 60mm, arc-shaped The central angle of the plate 232 can also be 60°, 75°, 90°, and the arc length can also be 40mm, 50mm, 70mm. The distance between the lower end of the vertical straight plate 231...

Abstract

The invention discloses an intercooler of an automobile supercharged engine. The intercooler comprises an air inlet structure, a core body and an air outlet structure, the core body is arranged between the air inlet structure and the air outlet structure and communicates with the air inlet structure and the air outlet structure, the air inlet structure comprises an inlet pipe and an air inlet chamber which communicate with each other, and a flow guide plate is arranged in the air inlet structure. One part of the flow guide plate is located in the inlet pipe, the other part of the flow guide plate is located in the air inlet chamber, and the flow guide plate is of an integrally formed structure and comprises an arc-shaped plate, a vertical straight plate connected with one end of the arc-shaped plate and a horizontal straight plate connected with the other end of the arc-shaped plate. According to the intercooler, the heat exchange effect of the core body can be improved, and the phenomenon that the intercooler is frozen is avoided.

Description

technical field [0001] The invention belongs to the field of engine air intake systems, and in particular relates to an intercooler of an automobile supercharged engine. Background technique [0002] With the development of automobile industry technology, supercharged engines are more and more favored by consumers. The reason why supercharged engines have the advantages of high comprehensive performance is that the intercooler plays a key role. After the supercharged high-temperature air is cooled by the intercooler, the intake air density can be increased, the effective charging efficiency of the cylinder can be improved, and the engine power can be increased. NO X emissions. [0003] The intercooler of the existing supercharged engine includes an air intake structure, an air outlet structure, and a core body arranged between the air intake structure and the air outlet structure and communicated with the air intake structure and the air outlet structure. One end of the i...
