To provide a structure of a heat exchanger for a refrigerator capable of reducing a pressure loss of a refrigerant in a heat exchanger using a refrigerant pipe having an inner fin, in the heat exchanger for a refrigerator.SOLUTION: In a heat exchanger 1 that has an inner fin on an inner peripheral surface and is equipped with a refrigerant pipe 10 in which straight pipe portions 14 and bent pipe portions 15 are alternately continued, the refrigerant pipe 10 is branched off to a plurality of circuits 11A and 11B between a refrigerant inlet and a refrigerant outlet. Fin groups 21 to 26 composed of a plurality of plate fins 20 arranged in parallel are provided, and the straight pipe portions 14 of the refrigerant pipe 10 penetrate the plate fins 20 of the fin groups 21 to 26 to integrate the refrigerant pipe 10 and the fin groups 21 to 26.SELECTED DRAWING: Figure 1 【課題】冷蔵庫用熱交換器において、インナーフィンを有する冷媒管を用いた熱交換器において冷媒の圧力損失を低減できる冷蔵庫用熱交換器の構造を提供する。【解決手段】内周面にインナーフィンを有し、直管部１４と曲管部１５とが交互に連続する冷媒管１０を備えた熱交換器１において、冷媒管１０を、冷媒入口と冷媒出口の間で複数の回路１１Ａ、１１Ｂに分岐させる。また、並列に配置された複数のプレートフィン２０からなるフィン群２１〜２６を有し、冷媒管１０の直管部１４がフィン群２１〜２６のプレートフィン２０を貫通することにより冷媒管１０とフィン群２１〜２６を一体化させる。【選択図】図１
