Claims

[Claims for Utility Model Registration] 1. A plurality of vertically long flat hollow bodies for circulating cooled fluid arranged in parallel, and spacer bars arranged at both upper and lower ends between adjacent hollow bodies. A heat exchange section formed of an air flow path orthogonal to the hollow body, and an inlet side and an outlet side joined to the upper and lower ends of the heat exchange section so that the cross section is U-shaped and the opening faces the hollow body side. In a heat exchanger consisting of a header, a bypass passage for a fluid to be cooled is provided between the inlet side and outlet side headers, and has a cross-sectional area larger than the cross-sectional area of the flat hollow body and communicates both headers. Heat exchanger. 2. It is formed by a plurality of vertically long flat hollow bodies for circulating the cooled fluid arranged in parallel, and spacer bars arranged at both the upper and lower ends between the adjacent hollow bodies, and which are perpendicular to the hollow bodies. In a heat exchanger consisting of a heat exchange section constituted by an air flow path, and a pair of headers having a U-shaped cross section and joined to the upper and lower ends of the heat exchange section so that the openings face the hollow body side, A partition is provided at a predetermined position in one of the headers to divide the inside of the header into two divided header parts, and between both divided header parts and the other header, a partition is provided at a predetermined position within the header. A heat exchanger that has a large cross-sectional area and is provided with a bypass passage for a fluid to be cooled that communicates both divided header portions with the other header.
