ブ型蒸発器。[Claim for Utility Model Registration] 1. In a Finch-Youb type evaporator of a refrigeration circuit, the refrigerant from the expansion valve is ventilated by meandering in a plurality of planes arranged in sequence along the ventilation path so as to be substantially orthogonal to the ventilation direction. A thin tube that flows from the upstream side to the downstream side, a thick tube that meanderes in a plane located upstream of any of the plurality of planes and has an inner diameter larger than the thin tube, and the thin tube. A Finch-Eube type evaporator, characterized in that it is equipped with a connecting pipe that connects the outlet part of the thick pipe with the inlet part of the thick pipe. 2. The Finch-Youb type evaporator according to claim 1, wherein the cross-sectional area of the thick tube is at least twice the cross-sectional area of the thin tube. 3. Utility model registration claim 2, characterized in that the thin tube and the thick tube meander as they move in the vertical direction, and the outlet portion of the thin tube and the inlet portion of the thick tube are both located below. Finch-Eube type evaporator as described in section.
