Description

本開示に係る熱交換器は、第１流体と第２流体との間で熱交換を行う熱交換器であって、内側を第１流体が流れるように構成された内部部材（２００）と、内側に内部部材を収容する容器であって、内部部材の周囲の空間を第２流体が流れるように構成されたケース（１００）と、を備える。ケースには、第１流体の入口である第１入口部（１１）と、第１流体の出口である第１出口部（１２）と、第２流体の入口である第２入口部（２１）と、第２流体の出口である第２出口部（２２）と、がそれぞれ設けられている。内部部材は、その長手方向に沿って内側を第１流体が流れるタンク（２１０，２２０，２３０，２１５）と、その長手方向がタンクの長手方向に対して垂直となるように、タンクに対して接続された管状の部材であって、タンクの長手方向に沿って並ぶように互いに間隔を空けて積層された複数のチューブ（２４０）と、を有するものである。チューブは、その断面が扁平形状となるように形成されている。複数のチューブが並んでいる方向を積層方向としたときに、第２入口部及び第２出口部は、いずれも、ケースのうち積層方向に沿った一方側の面、である接続面（Ｓ）に設けられている。 The heat exchanger according to the present disclosure is a heat exchanger that exchanges heat between a first fluid and a second fluid, and includes an internal member (200) configured so that the first fluid flows inside. A container (100) for accommodating an internal member, which is configured to allow a second fluid to flow in a space around the internal member, is provided. In the case, a first inlet portion (11) which is an inlet of the first fluid, a first outlet portion (12) which is an outlet of the first fluid, and a second inlet portion (21) which is an inlet of the second fluid. And a second outlet portion (22), which is an outlet of the second fluid, are provided respectively. The internal members are the tanks (210, 220, 230, 215) through which the first fluid flows along the longitudinal direction thereof, and the tank so that the longitudinal direction thereof is perpendicular to the longitudinal direction of the tank. It is a connected tubular member having a plurality of tubes (240) laminated at intervals so as to be arranged along the longitudinal direction of the tank. The tube is formed so that its cross section has a flat shape. When the direction in which the plurality of tubes are lined up is the stacking direction, the second inlet portion and the second outlet portion are both one side surface of the case along the stacking direction, that is, the connecting surface (S). It is provided in.
