To provide a heat exchanger capable of improving variation in temperature distribution of air after heat exchange.SOLUTION: A heat exchanger 10 includes a core portion 20, and tanks 30, 40. The core portion 20 has a plurality of tubes 21 arranged with prescribed clearances, and a plurality of fins 22 arranged in the clearances formed between the plurality of tubes 21. The tanks 30, 40 are connected to end portions of the plurality of tubes 21. Clearances are formed between the tanks 30, 40 and end portions of the fins 22. When a width of the clearance is L, and a pitch of the fins is Fp, the width L of the clearance and the pitch Fp of the fins satisfy: L<-0.58×Fp2+4.65×Fp-2.8.SELECTED DRAWING: Figure 1

    【課題】熱交換後の空気の温度分布のばらつきを改善することが可能な熱交換器を提供する。【解決手段】熱交換器10は、コア部20と、タンク30,40と、を備える。コア部20は、所定の隙間を有して配置される複数のチューブ21、及び複数のチューブ21の間に形成される隙間に配置される複数のフィン22を有する。タンク30,40は、複数のチューブ21の端部に接続される。タンク30,40とフィン22の端部との間には隙間が形成されている。隙間の幅を「L」とし、フィンのピッチを「Fp」とするとき、隙間の幅L及びフィンのピッチFpは「L<-0.58×Fp2+4.65×Fp-2.8」を満たしている。【選択図】図1
