To provide a cooler for a vehicle, which can be miniaturized.SOLUTION: A cooler 1 for a vehicle comprises a radiator 2 and an air flow rate controller 3 which comprises an adjustment plate 9 moving in a vertical direction and a guide member 11 for guiding the adjustment plate 9 and controls a rate of air flow flowing toward the radiator 2. The radiator 2 has: a plurality of heat exchanger tubes 4 for coolant which have a lengthwise direction in a longitudinal direction and are arranged at intervals in the vertical direction; and fins 5 each of which is arranged in a ventilation space 7 formed between heat exchanger tubes 4 for coolant adjacent to each other. A plurality of air passage holes 12 comprising long holes having a lengthwise direction in the longitudinal direction and having a breadthwise direction in the vertical direction are formed in the adjustment plate 9 at intervals in the vertical direction. A size in the breadthwise direction of the air passage holes 12 is made equal to or smaller than that in the breadthwise direction of the ventilation spaces 7 between the heat exchanger tubes 4 for coolant adjacent to each other, and a pitch between the heat exchanger tubes 4 for coolant adjacent to each other and that between the air passage holes 12 adjacent to each other are equalized.SELECTED DRAWING: Figure 1
【課題】小型化を図りうる車両用冷却装置を提供する。【解決手段】車両用冷却装置1は、ラジエータ2と、上下方向に移動する調整板9および調整板9を案内するガイド部材11よりなりかつラジエータ2へ向かって流れる空気流量を調節する空気流量調整部3とを備えている。ラジエータ2は長手方向が左右方向を向きかつ上下方向に間隔をおいて配置された複数の冷却液用熱交換管4と、隣り合う冷却液用熱交換管4どうしの間に形成された通風間隙7に配置されたフィン5とを有する。調整板9に、長手方向が左右方向を向きかつ幅方向が上下方向を向いた長穴からなる複数の空気通過穴12を上下方向に間隔をおいて形成する。空気通過穴12の幅方向の寸法を隣り合う冷却液用熱交換管4間の通風間隙7の幅方向の寸法以下とし、隣り合う冷却液用熱交換管4間のピッチと隣り合う空気通過穴12間のピッチとを同一にする。【選択図】図1
