PROBLEM TO BE SOLVED: To decrease the number of components and simplify a configuration in relation to a heat exchanger in which a plurality of channels in which an external fluid circulates is divided in a tube longitudinal direction and a manufacturing method of the heat exchanger.SOLUTION: A heat exchanger comprises two evaporation units 10 and 20 disposed in series to an air flow direction, a space formed between tubes 111 and 211 adjacent in a tube stacking direction forms an air passage 60, a space formed between the tubes 111 and 211 adjacent in the air flow direction forms a tube clearance 61 communicating with the air passage 60, a partition portion 80 separating the air passage 60 in a tube longitudinal direction is provided in the air passage 60, the partition portion 80 includes a pair of engagement pieces 81 and 82 extending in the air flow direction and elastically deformable, a protruding portion 84 engaged with the tube clearance 61 is provided on each of the paired engagement pieces 81 and 82, and the partition portion 80 is inserted into the air passage 60 from upstream or downstream in the air flow direction.
【課題】外部流体が流通する流路がチューブ長手方向に複数に区画された熱交換器およびその製造方法において、部品点数を削減して構成を簡素化する。【解決手段】空気流れ方向に対して直列に配置された2つの蒸発部10、20を備え、チューブ積層方向に隣り合うチューブ111、211間に形成される空間は空気通路60を形成しており、空気の流れ方向に隣り合うチューブ111、211間に形成される空間は、空気通路60と連通するチューブ間隙間61を形成しており、空気通路60には、当該空気通路60をチューブ長手方向に仕切る仕切部80が設けられており、仕切部80は、空気流れ方向に延びる弾性変形可能な一対の係合片81、82を有して構成されており、一対の係合片81、82それぞれには、チューブ間隙間61に係合された突起部84が設けられており、仕切部80は、空気流れ方向の上流側または下流側から空気通路60に挿入されている。【選択図】図8
