To obtain a vehicular heat exchanger cooling structure capable of improving cooling performance of a heat exchanger.SOLUTION: A grille 24 is disposed at a vehicle front side of an air conditioner condenser 20 and has an opening 24A. In a side frame part 30A of an air guide part 26, a substantially cylindrically formed channel member 29 surrounds the opening 24A in a front view of the vehicle. An inlet 34 communicates with an inside and an outside of the channel member 29, and a cooling fan 28 blows air from the inlet 34 to the inside of the channel member 29 and flows the air from an outlet 36 to a vehicle rear side. Here, wind with increased air quantity can be caused to flow from the air guide part 26 to a radiator 18 and the air conditioner condenser 20 because the outlet 36 of the channel member 29 has a smaller opening area than the inlet 34 to increase a flow rate of the air flowing from the outlet 36 to the vehicle rear side so that air blown out from the outlet 36 of the side frame part 30A takes in air flowing through the opening 24A of the grille 24.SELECTED DRAWING: Figure 3

    【課題】熱交換器の冷却性能を向上させることができる車両用熱交換器冷却構造を得る。【解決手段】グリル24は、エアコンコンデンサ20の車両前方側に設けられると共に、開口部24Aを有している。導風部26の側枠部30Aは、略筒状に形成された流路部材29が車両正面視にて開口部24Aを囲んでいる。入口34は、流路部材29の内部と外部とを連通し、冷却ファン28が入口34から流路部材29の内部に送風し、出口36から車両後方側へ流される。ここで、流路部材29の出口36は、入口34より開口面積が小さくされていることから、出口36から車両後方側へと流れる空気の流速が高まり、側枠部30Aの出口36から吹き出された空気がグリル24の開口部24A内を通る空気を引き込むため、導風部26から風量が増加した風をラジエータ18及びエアコンコンデンサ20へ流すことができる。【選択図】図3
