To provide an intercooler cooling structure capable of achieving both improvement in engine output and ensuring of fuel efficiency at appropriate time.SOLUTION: A vent hole 5 is installed on a hood 1 at a position closer to a front section of a vehicle than an opening section 4 of an air guiding duct 3 guiding travel wind to an intercooler 2. The vent hole 5 is communicated with a negative pressure generation section in an engine intake system through a ventilation passage 6 which is communicated with the air guiding duct 3 through a communication passage 7. A ventilation passage opening-closing valve 8 and a communication passage opening-closing valve 9 which opens and closes a ventilation duct side opening section 7a of the communication passage 7 are arranged at a position closer to an engine intake system than the communication passage 7. A valve body 11 of the ventilation passage opening-closing valve 8 is configured to be opened with a negative pressure in the ventilation passage 6. A valve body section 13 of the communication passage opening-closing valve 9 is configured to open a communication opening section 7a when the negative pressure is small with the negative pressure of the engine intake system introduced into a pneumatic cylinder 16. The valve body section 13 is connected to an air guide section 14 guiding the travel wind in the air ventilation duct 3 to the communication passage 7.SELECTED DRAWING: Figure 1

    【課題】エンジンの出力向上と燃費の確保を適時に両立することが可能なインタークーラー冷却構造を提供する。【解決手段】インタークーラー2に走行風を導風する導風ダクト3の開口部4よりも車両前方側の位置でフード1に通気口5を設け、この通気口5とエンジン吸気系の負圧発生部位を通気路6で連通し、通気路6と導風ダクト3を連通路7で連通する。この連通路7よりもエンジン吸気系側に通気路開閉弁8を設けると共に、連通路7の導風ダクト側開口部7aを開閉する連通開口部開閉弁9を設ける。通気路開閉弁8の弁体11が通気路6内の負圧で開弁するように構成すると共に、空圧シリンダ16にエンジン吸気系の負圧を導入して負圧が小さいときに連通開口部開閉弁9の弁体部13が連通開口部7aを開くように構成する。弁体部13には、連通路7内に導風ダクト3内の走行風を導入する導風部14を連設する。【選択図】図1
