Title (EN) REDUCING AGENT TANK AND WORK VEHICLE
(FR) RÉSERVOIR D'AGENT DE RÉDUCTION ET VÉHICULE DE TRAVAIL
(JA) 還元剤タンクおよび作業車両
Abstract:
(EN) Provided is a reducing agent tank that allows a top lid and a heat exchanger to be removed while keeping the path length of the heat exchanger inside the reducing agent tank long. A first pipeline (50) and a second pipeline (60) that constitute a heat exchanger (40) each comprise: an extended part (54, 64) that extends along a bottom surface (36) from the lower end of a hanging part (41) toward a side surface (35a) of a container body (33); and a rising part (55, 65) that extends along the side surface (35a) from the tip end of the extended part (54, 64) toward the upper surface (34) of the container body (33) up to a fold-back part (59). The dimension L1 indicating the length of the extended part (54, 64) along the bottom surface (36) is greater than the dimension LD indicating the maximum inner measurement length of an opening (31). The rising part (55, 65) and the fold-back part (59) form a tip-end bent part (45) of the heat exchanger (40), and the rising length of the tip-end bent part (45) is shorter than the dimension SD indicating the minimum inner measurement length that passes through the center of the opening (31).
(FR)  L'invention concerne un réservoir d'agent de réduction, lequel permet le retrait d'un couvercle supérieur et d'un échangeur thermique tout en conservant une longueur importante du canal de l'échangeur thermique à l'intérieur du réservoir d'agent de réduction. Un premier conduit (50) et un deuxième conduit (60) qui constituent un échangeur thermique (40) possèdent chacun: une partie allongée (54, 64) qui s'étend en suivant une face inférieure (36), de l'extrémité inférieure d'une partie suspendue (41) en direction d'une face latérale (35a) d'un corps de récipient (33); et une partie verticale (55, 65) qui s'étend en suivant la face latérale (35a), de l'extrémité avant de la partie allongée (54, 64) en direction d'une face supérieure (34) du corps de récipient (33) jusqu'à une partie de repli (59). La dimension (L1) représentant la longueur de la partie allongée (54, 64) le long de la face inférieure (36) est supérieure à la dimension (LD) représentant la longueur interne maximale d'un orifice (31). La partie verticale (55, 65) et la partie de repli (59) forment une partie (45) d'extrémité incurvée de l'échangeur thermique (40). La longueur verticale de la partie (45) d'extrémité incurvée est inférieure à la dimension (SD) représentant la longueur interne minimale du centre de l'orifice (31).
(JA)  還元剤タンク内における熱交換器の経路長を長く確保しつつ、天蓋および熱交換器の取外しを可能にする、還元剤タンクを提供する。熱交換器(40)を構成している第1管路(50)と第2管路(60)とは、それぞれ、垂下部(41)の下端から底面(36)に沿って容器本体(33)の側面(35a)へ向かって延びる延伸部(54,64)と、延伸部(54,64)の先端から側面(35a)に沿って容器本体(33)の上面(34)へ向かって折り返し部(59)まで延びる立上り部(55,65)とを有している。延伸部(54,64)の底面(36)に沿う長さを示す寸法L1は、開口(31)の最大内法長さを示す寸法LDよりも大きい。立上り部(55,65)および折り返し部(59)は、熱交換器(40)の先端屈曲部(45)を形成し、先端屈曲部(45)の立上り長さは開口(31)の中心を通る最小内法長さを示す寸法SDよりも小さい。
