Abstract:
(EN) Provided is a heat exchanger that is compact and inexpensive and that is highly efficient and pressure-resistant. This heat exchanger 10 performs heat exchange between hydrogen and a refrigerant. Refrigerant flow paths and hydrogen flow paths are provided in a layered shape and in an alternating manner in a Z direction orthogonal to the flow path direction in portions at which heat exchange is performed. The refrigerant flow paths have ten refrigerant upstream narrow paths 48 and ten refrigerant downstream narrow paths 50 that are arranged in parallel in a Y direction, and honeycomb parts 52 that are provided between the refrigerant upstream narrow paths 48 and the refrigerant downstream narrow paths 50. First branching/merging parts 54 and second branching/merging parts 56 are provided in an alternating manner to the honeycomb parts 52. In the first branching/merging parts 54, a previous flow path is branched into two partial flow paths 60, 60, and a next flow path is formed by the merging together of adjacent partial flow paths 60, 60. In the second branching/merging parts 56 as well, a flow path is branched into two partial flow paths 62, 62 and adjacent partial flow paths 62, 62 are merged in the same manner. The hydrogen flow paths also have similar honeycomb parts 52.
(FR) L'invention concerne un échangeur de chaleur qui est compact et peu coûteux et qui est hautement efficace et résistant à la pression. L'échangeur de chaleur (10) selon l'invention réalise un échange de chaleur entre l'hydrogène et un fluide frigorigène. Des trajets d'écoulement de fluide frigorigène et des trajets d'écoulement d'hydrogène sont disposés selon une forme en couches et de manière alternée dans une direction Z orthogonale à la direction de trajet d'écoulement dans des parties où se produit un échange de chaleur. Les trajets d'écoulement de fluide frigorigène ont dix trajets étroits amont (48) de fluide frigorigène et dix trajets étroits aval (50) de fluide frigorigène qui sont agencés en parallèle dans une direction Y et des parties en nid d'abeilles (52) qui sont disposées entre les trajets étroits amont (48) de fluide frigorigène et les trajets étroits aval (50) de fluide frigorigène. Des premières parties de ramification/fusion (54) et des secondes parties de ramification/fusion (56) sont disposées de manière alternée sur les parties en nid d'abeilles (52). Dans les premières parties de ramification/fusion (54), un trajet d'écoulement précédent est ramifié en deux trajets d'écoulement partiels (60, 60) et un trajet d'écoulement suivant est formé par la fusion de trajets d'écoulement partiels adjacents (60, 60). Dans les secondes parties de ramification/fusion (56), un trajet d'écoulement est ramifié en deux trajets d'écoulement partiels (62, 62) et des trajets d'écoulement partiels adjacents (62, 62) sont fusionnés de la même manière. Les trajets d'écoulement d'hydrogène ont également des parties en nid d'abeilles (52) similaires.
(JA) 高効率かつ高耐圧であるとともに小型で廉価な熱交換器を提供する。熱交換器10は水素と冷媒との間で熱交換を行う。冷媒流路と水素流路は、熱交換が行われる部分で流路方向と直交するZ方向に交互に積層状に設けられる。冷媒流路は、Y方向に並列する10本の冷媒上流細路48及び10本の冷媒下流細路50と、これらの冷媒上流細路48及び冷媒下流細路50との間に設けられたハニカム部52とを有する。ハニカム部52には第1分岐合流部54と第2分岐合流部56が交互に設けられている。第1分岐合流部54では、直前の流路が2本の分流路60,60に分岐するとともに隣接する分流路60,60同士が合流して次の流路を形成する。第2分岐合流部56も同様に2つの分流路62,62に分岐するとともに隣接する分流路62,62が合流する。水素流路も同様のハニカム部52を有する。
