An embodiment of an integrated charge air water cooled intercooler of the present invention is shown in fig. 1, comprising an intercooler housing 3 integrally integrated with a supercharger 1, an intake manifold 2, and a cooling core 4 disposed within the intercooler housing 3;
the cooling inner 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 shell 3, the plurality of cooling pipes 41 are distributed in a staggered manner up and down, and a flow passage 42 for allowing the 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 both open ends of the two fin groups 43 form openings a431 and b432, respectively, the fin groups 43 include a plurality of arc-shaped fins 433 distributed along the extending direction of the cooling tube 41, and the plurality of arc-shaped fins have gaps 434 between the 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 way, hot air in the supercharger 1 collides with the fin groups 43 of the cooling pipes 41 to circulate in the flow channels 42 and finally is discharged to the air inlet manifold 2, so that the distribution position of the cooling pipes 41 and the arrangement of the flow channels 42 increase the cooling path of the hot air in the intercooler shell 3, the cooling effect is improved, and the effect of avoiding the hot air from generating vortex in the intercooler shell 3 is further achieved.
The reason for avoiding vortex generation is as follows: the fin group 43 is formed by a plurality of arc fins 433, hot air in the supercharger 1 rapidly enters the intercooler shell 3 and has a certain vortex, the plurality of arc fins 433 conduct diversion guiding on the vortex, and then pass through the runner 42 and pass through the next cooling pipe 41, so that the plurality of arc fins 433 arranged at intervals have a certain diversion effect on the vortex, the vortex disappears due to the combination with the design of the runner 42, and the plurality of arc fins 433 have a certain guiding effect on the hot air in the supercharger 1, so that a traditional guide plate is not needed, and the lightweight design of a vehicle is realized.
The two open ends of the two fin groups 43 form openings a431 and b432, respectively, and the reason for this design is that: if the arc fins 433 are designed into an annular structure, the split hot air continuously rotates around the arc fins 433 along with the flow inertia of the split hot air, the split hot air is converged into vortex again, which is not beneficial to the rapid discharge of pressurized gas, the arrangement of the openings a431 and b432 effectively solves the problem, the flow inertia of the hot air is reduced, the split hot air flows to the openings a431 and b432 and flows to the fin group 43 of the next cooling tube 41 through the flow channel, and the generation of vortex is further avoided.
On the basis of the embodiment, the opening a431 and the opening b432 are symmetrically arranged along the axis 436 of the cooling pipe 41, a first virtual line 435 is formed by the center point of the opening a431, the center point of the opening b432 and the center of the cooling pipe 41 on the same longitudinal section, the first virtual line 435 is inclined from the outlet end of the supercharger 1 to the inlet end direction of the intake manifold 2, so that hot air is conveniently discharged to the intake manifold 2 along with the inertia of gas flow after being cooled by the cooling pipe 41, and vortex flow generated inside the intercooler shell 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 hot air is discharged from the supercharger 1 to the intercooler housing 3 at the same flow rate, and the split air ensures a uniform cooling effect.
On the basis of the 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 forms an included angle of 30-45 degrees with the first virtual line 435.
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 ° with the first virtual line 435, for two design reasons:
1. the angle control ensures that air accurately enters the air inlet manifold 2, hot air flows into the flow channel 42 through the inertia weakening of the opening a431 and the opening b432 by cooling and shunting of the fin groups, is guided by the fin groups on the next cooling pipe 41, and finally changes the flowing direction of 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 at 30-45 degrees, the cooled air is rapidly entered into the air inlet manifold 2, and the supercharging efficiency is improved;
2. when the hot air in the supercharger 1 rapidly enters the intercooler housing 3, the cooling pipe 41 firstly contacted with the hot air is heated at a high speed, and the cooling pipe can generate maximum thermal stress to influence the structural strength of the cooling pipe, and the angle design ensures that the hot air firstly encounters the fin arc 433 and then is guided along with the diversion of the arc fin 433, so that the maximum thermal stress concentration point is avoided, and if the hot air enters the intercooler housing 3, the opening a431 and the opening b432 are directly contacted, and the maximum thermal stress concentration point is generated to damage the service life of the cooling pipe 41.
Based on the two points, the angular design not only facilitates the rapid directed flow of hot air, but also avoids the creation of a point of maximum thermal stress concentration to the cooling tube 41.
On the basis of the present embodiment, the thickness of the cooling tube 41 is identical to the length of the arc-shaped fins 433, the length of the arc-shaped fins 433 ensures the heat radiation of the cooling tube 41 according to the cooling tube 41, and the arc-shaped fins 433 are higher than the cooling tube 41, so that the lightweight design cannot be realized.
On the basis of the embodiment, one side of the intercooler casing 3 is provided with a water inlet tank 5, the other side of the intercooler casing 3 is provided with a water outlet tank 6, two sides of the intercooler casing 3 are respectively provided with a plurality of through holes 7 embedded at two ends of the cooling pipe 41, two ends of the cooling pipe 41 are embedded in the corresponding through holes 7, the side ends of the cooling pipe 7 are in sealing fit with the corresponding through holes 7 through sealing rings, the water inlet tank 5 and the water outlet tank 6 are communicated with the intercooler casing 3 through the through holes 7, the water inlet tank 5 is provided with a cooling water inlet pipe 8, and the water outlet tank 6 is provided with a cooling water outlet pipe 9.
On the basis of the embodiment, the water inlet tank body 5 and the water outlet tank body 6 are gradually gathered from the side ends of the intercooler shell 3 to the directions of the corresponding cooling water inlet pipe 8 and the cooling water outlet pipe 9 respectively to form a curved surface smooth transition section 10, and the smooth transition section 10 has a certain guiding effect on the inlet and outlet of cooling water.
