Intake cooling system of turbocharged engine

摘要

The present invention relates to an intake cooling device of a turbocharger-attached engine, and more particularly, to an apparatus for cooling an intake air installed at an inter cooler outlet side of a turbocharger engine for automobiles. It is to increase the charging efficiency by cooling the intake air at the cooler outlet side.;According to the present invention, a turbine 5 of a turbocharger 4 driven by exhaust gas energy is installed in an exhaust pipe 2 of an engine 1, and a compressor 6 is installed coaxially with the turbine 5. Pressurizes the intake air, and connects the inter cooler 7 to the outlet of the compressor 6 and the intake air pipe 3 connected to the engine 1, and thus the outlet air intake pipe 3 of the inter cooler 7. ) Is provided by the cooling means 8 for recooling the intake air cooled in the inter cooler 7 by the cold air generated during the operation of the air conditioner.;The cooling means 8 cuts the intake airway pipe 3 to connect the cooling pipe body 80 and at the same time to install the heat transfer fin 81 to form a plurality of passages 82, the cooling pipe body 80 The cover 84 is installed to form a cold air passage 83 on the outside thereof, and a cold air inlet 85 and a cold air outlet 85 ′ are installed at the cover 84, and the valve 86 is provided at the cold air inlet 85. By installing and artificially opening or closing the actuator or connected to the actuator of the shaft of the valve 86 by the electronic control unit (not shown) to open and close the operation in relation to the atmospheric temperature.
