In the present invention, unless otherwise specified and limited, terms such as "connected," "provided," "having," and the like are to be understood in a broad sense, and may be, for example, fixedly connected, detachably connected, or integrally connected, mechanically connected, or directly connected, and may be connected through an intermediate medium, so that those skilled in the art can understand the basic meaning of the above terms in the present invention according to specific situations.

Fig. 1 shows an integrated intake water-cooled intercooler in accordance with an embodiment of the present invention, which includes an intercooler housing 3 integrally formed with a supercharger 1 and an intake manifold 2, and a cooling core 4 disposed in the intercooler housing 3;

the cooling core 4 is composed of a plurality of hollow cooling pipes 41, the plurality of cooling pipes 41 are arranged along the extending direction of the intercooler housing 3, the plurality of cooling pipes 41 are distributed in a vertically staggered manner, and a flow passage 42 for gas in the supercharger 1 to pass through is formed among the plurality of cooling pipes 41;

the cooling tube 41 has two fin groups 43 provided on the outer wall of the cooling tube 41, the two fin groups 43 are provided in correspondence with each other, and openings a431 and b432 are formed at both open ends of the two fin groups 43, the fin groups 43 include a plurality of arc-shaped fins 433 distributed along the extending direction of the cooling tube 41, and gaps 434 are provided between the plurality of arc-shaped fins 433.

In the invention, the cooling inner core 4 is provided with the plurality of cooling pipes 41 which are distributed in a vertically staggered manner, so that the hot air in the supercharger 1 collides with the fin groups 43 of the cooling pipes 41 and flows in the flow passage 42, and is finally discharged to the intake manifold 2, the distribution positions of the cooling pipes 41 and the arrangement of the flow passage 42 increase the cooling path of the hot air in the intercooler housing 3, the cooling effect is improved, and the effect of avoiding the hot air from generating vortex in the intercooler housing 3 is further achieved.

The reason for avoiding the generation of the eddy current is as follows: fin group 43 comprises a plurality of arc fins 433, hot-air in the booster 1 gets into intercooler casing 3 fast and has certain vortex, a plurality of arc fins 433 shunt the direction to the vortex, pass through runner 42 through next cooling tube 41 again, therefore the arc fins 433 that a plurality of intervals set up have certain reposition of redundant personnel effect to the vortex, combine with runner 42's design, make the vortex disappear, because a plurality of arc fins 433 have certain guide effect to the hot-air in the booster 1, consequently also need not traditional deflector, the lightweight design of vehicle has been realized.

The reason why the opening a431 and the opening b432 are formed at the open ends of the two fin groups 43 is that: if the arc-shaped fins 433 are designed into an annular structure, the hot air after being split continuously rotates around the arc-shaped fins 433 along with the flowing inertia of the hot air, the hot air after being split is converged into a vortex again, which is not beneficial to the rapid discharge of the pressurized gas, and the two fin groups 43 of the design effectively solve the problem, the arrangement of the openings a431 and the openings b432 reduces the flowing inertia of the hot air, and the hot air after being split flows to the openings a431 and the openings b432 and then flows to the fin group 43 of the next cooling tube 41 through the flow channel, so that the generation of the vortex is further avoided.

In the present embodiment, the openings a431 and b432 are symmetrically arranged along the axis 436 of the cooling pipe 41, the center point of the opening a431, the center point of the opening b432 and the center point of the cooling pipe 41 on the same longitudinal section form a first virtual line 435, and the first virtual line 435 is inclined from the outlet end of the supercharger 1 to the inlet end of the intake manifold 2, so that the hot air is cooled by the cooling pipe 41 and then is discharged to the intake manifold 2 along with the gas flow inertia, and the generation of vortex inside the intercooler housing 3 is avoided.

On the basis of the present embodiment, the first virtual lines 435 on the plurality of cooling pipes 41 are parallel to each other, and the branched air ensures a uniform cooling effect when the hot air is discharged from the supercharger 1 to the intercooler housing 3 at the same flow rate.

On the basis of the present embodiment, the outlet end of the supercharger 1 and the inlet end of the intake manifold 2 form a second virtual line 437, and the second virtual line 437 and the first virtual line 435 form an angle of 30-45 °.

The first virtual line 435 is inclined from the outlet end of the supercharger 1 to the inlet end of the intake manifold 2, and the second virtual line 437 forms an included angle of 30-45 degrees with the first virtual line 435, for two reasons:

firstly, the angle control ensures that air accurately enters the intake manifold 2, hot air flows into the flow channel 42 through inertia weakening at the opening a431 and the opening b432 through the cooling flow distribution of the fin group, then the hot air is guided by the fin group on the next cooling pipe 41, and finally the flow direction is changed by 30-45 degrees through the opening a431 and the opening b432, so that the included angle between the first virtual line 435 and the second virtual line 437 is set to be 30-45 degrees, the cooled air rapidly enters the intake manifold 2, and the supercharging efficiency is improved;

secondly, when the hot air in the supercharger 1 enters the intercooler housing 3 quickly, the cooling pipe 41 which is firstly contacted with the hot air is heated at the highest speed, at the moment, the cooling pipe can generate the maximum thermal stress to influence the structural strength of the cooling pipe, and the angle design ensures that the hot air firstly meets the fin arc 433 and then is guided by shunting along with the arc fin 433, so that the maximum thermal stress concentration point is avoided, and if the hot air enters the intercooler housing 3 to be directly contacted with the opening a431 and the opening b432, the maximum thermal stress concentration point is generated to damage the service life of the cooling pipe 41.

Based on the above two points, the angle design not only facilitates the rapid guiding flow of the hot air, but also avoids generating the maximum thermal stress concentration point to the cooling pipe 41.

In this embodiment, the thickness of the cooling tube 41 is equal to the length of the arc fin 433, the length of the arc fin 433 ensures the heat radiation performance of the cooling tube 41 according to the cooling tube 41, and the arc fin 433 is higher than the cooling tube 41, so that the design of light weight cannot be realized.

On this embodiment basis, one side of intercooler casing 3 has into water box 5, the opposite side of intercooler casing 3 has out water box 6, the both sides of intercooler casing 3 have a plurality of through-holes 7 of holding the both ends embedding of cooling tube 41 respectively, in the through-hole 7 that the both ends embedding of cooling tube 41 corresponds and the side of cooling tube 7 and the through-hole 7 that corresponds realize sealed cooperation through the sealing washer, into water box 5, it realizes the intercommunication through-hole 7 and intercooler casing 3 to go out water box 6, it advances pipe 8 to have the cooling water on the box 5 to intake, it goes out water outlet pipe 9 to have the cooling water on the box 6.

On the basis of the embodiment, the water inlet tank body 5 and the water outlet tank body 6 are gradually gathered together from the side end of the intercooler casing 3 to the corresponding directions of the cooling water inlet pipe 8 and the cooling water outlet pipe 9 to form a curved smooth transition section 10, and the smooth transition section 10 has a certain guiding effect on the inlet and outlet of the cooling water.

It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only for the purpose of illustrating the principles of the present invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims.
