PROBLEM TO BE SOLVED: To provide a fluid recovery box for a heat exchanger capable of suppressing the capacity to a minimum. SOLUTION: The fluid recovery box includes rectangular recovery plates 26, 46 with a row of substantially square attachment holes 28 inserted with tubes of the heat exchanger provided in a long edge direction, and covers 45, 51 covering the recovery plates, and each attachment hole 28 is provided so as to extend in a first direction being a short edge direction of the recovery plates 26, 46. The cover 45 is composed of a middle plate 43 having a plurality of slots provided so as to extend in a second direction orthogonal to the first direction, and waveform plates 44, 50 covering it. The middle plate 43 and the waveform plates 44, 50 are mutually soldered such that the slots of the middle plate 43 and protrusions of the waveform plates 44, 50 match. A space for coolant recovery is partitioned such that the attachment holes 28 communicate with each other by the slots of the middle plate 43 and the protrusions of the waveform plates 44, 50.
