Background technique
At the machine that starts of automobile, after air entered worm gear supercharging, the temperature of air can significantly raise, and density also can correspondingly diminish, and the air of rising temperature can affect the charging efficiency of motor, therefore needs to reduce air temperature.Intercooler is to be used for cooling in the automobile engine system from worm wheel pressure booster high-temperature gas out, before pressurization gas enters engine intake it is cooled off.At present, existing intercooler mainly comprises core body and is separately positioned on the air chamber of core body both sides, heat dissipating pipe is set in the core body, heat dissipating pipe is vertical with the length direction of core body, the heat diffusion area of this heat dissipating pipe is little, and can increase the obstruction power of gas, affects the inflation effect of motor.In addition, suction port and the air outlet of the air chamber of existing intercooler both sides generally only have one, and Throughput is little, is unfavorable for the inflation of motor.
Summary of the invention
The purpose of this utility model is: for the deficiencies in the prior art, the utility model provides the double nip intercooler of a kind of good charging, excellent in heat dissipation effect.
To achieve these goals, the utility model has adopted following technological scheme:
A kind of double nip intercooler, comprise core body, one end of core body is provided with suction chamber, the other end of core body is provided with discharge chamber, described suction chamber comprises the suction chamber body, one side of suction chamber body is sealed and matched with core body and is connected, opposite side is provided with two suction ports, discharge chamber comprises the discharge chamber body, and a side of discharge chamber body is sealed and matched with core body and is connected, and opposite side is provided with two air outlets, the bore of described air outlet is less than the bore of suction port, be provided with some heat dissipating pipes in the described core body, the length direction of described heat dissipating pipe is consistent with the length direction of core body, and described heat dissipating pipe is provided with the radiating fin of some bendings.
As preferably, the outer side wall of described suction port is provided with the installation screw thread.After adopting above-mentioned preferred version, be convenient to the installation that closely cooperates of suction chamber and motor worm gear supercharging device, install more firm.
As preferably, described radiating fin adopts the mode of welding to be arranged on the heat dissipating pipe.After adopting above-mentioned preferred version, radiating fin is more firm with cooperating of heat dissipating pipe.
As preferably, described suction chamber cooperates the installation place to be provided with sealing joint strip with core body, and described suction chamber is provided with suction chamber protection flange near an end of core body.After adopting above-mentioned preferred version, the setting of sealing joint strip can make the sealing of suction chamber and core body that better effects if is installed, and simultaneously, when the end of suction chamber and core body being installed cooperation, flange can be avoided the sharp edge injury operator of suction chamber end.
As preferably, described discharge chamber cooperates the installation place to be provided with sealing joint strip with core body, and described discharge chamber is provided with discharge chamber protection flange near an end of core body.After adopting above-mentioned preferred version, the setting of sealing joint strip can make the sealing of discharge chamber and core body that better effects if is installed, and simultaneously, when the end of discharge chamber and core body being installed cooperation, flange can be avoided the sharp edge injury operator of discharge chamber end.
As preferably, described core body is provided with the protecting sheet of fitting and arranging with the core body outer side wall outward.After adopting above-mentioned preferred version, can effectively strengthen the intensity of core body outer side wall.
As preferably, the outside of described discharge chamber is provided with some stiffening ribs.After adopting above-mentioned preferred version, can strengthen the intensity of discharge chamber.
Double nip intercooler of the present utility model is provided with two suction ports and two air outlets, gas flow is larger, can provide larger aeration quantity for motor, the inflation better effects if simultaneously, increases radiating fin at heat dissipating pipe, increased heat diffusion area, improved radiating effect, and the heat dissipating pipe direction is consistent with the core body length direction, has guaranteed the smoothness of gas.
Embodiment
As depicted in figs. 1 and 2, embodiment of the present utility model is a kind of double nip intercooler specifically, comprises core body 1, and an end of core body 1 is provided with suction chamber 2, and the other end of core body 1 is provided with discharge chamber 3.Suction chamber 2 comprises suction chamber body 21, and a side of suction chamber body 21 is sealed and matched with core body 1 and is connected, and opposite side is provided with two suction ports 22, and the outer side wall of suction port 22 is provided with installs screw thread 221.Discharge chamber 3 comprises discharge chamber body 31, one side of discharge chamber body 31 is sealed and matched with core body 1 and is connected, opposite side is provided with two air outlets 32, the bore of air outlet 32 is less than the bore of suction port 22, be provided with heat dissipating pipe 4 in the core body 1, the length direction of heat dissipating pipe 4 is consistent with the length direction of core body 1, is welded with crooked radiating fin 41 on the heat dissipating pipe 4.The core body 1 outer protecting sheet 11 of fitting and arranging with core body 1 outer side wall that is provided with.
Suction chamber 2 cooperates the installation place to be provided with sealing joint strip 5 with core body 1, and suction chamber 2 is provided with suction chamber protection flange 23 near an end of core body 1.Discharge chamber 3 cooperates the installation place to be provided with sealing joint strip 5 with core body 1, and discharge chamber 3 is provided with discharge chamber protection flange 33 near an end of core body 1.The outside of discharge chamber 3 is provided with stiffening rib 34.
The working principle of the working principle of double nip intercooler of the present utility model and the intercooler of prior art is basic identical, difference is: double nip intercooler of the present utility model is provided with two suction ports 22 and two air outlets 32, increased throughput, while heat dissipating pipe 4 and the identical setting of core body 1 length direction, increased the gas fluency, in addition, set up radiating fin 41 on the heat dissipating pipe 4, guaranteed radiating effect.
