A heat exchanger with which a fluid to be treated or a generated gas can be prevented from stagnating in a heat transfer part, which can be disassembled for good washability, and which can be coated or lined. The heat exchanger is provided with tow flow passages, i.e. a first flow passage and a second flow passage, within a space formed between an inner tube and an outer tube which are concentric to each other. A spiral heat transfer body is disposed between the inner tube and the outer tube, and the spiral heat transfer body has a cross-sectional shape that is substantially triangular in the axial-direction cross section. The space is partitioned into the first flow passage and the second flow passage by the spiral heat transfer body, and heat is exchanged via the spiral heat transfer body between a first fluid flowing within the first flow passage and a fluid flowing within the second flow passage.

A heat exchanger has a structure in which a heat exchanger main body through which coolant flows is obliquely installed in a box-shaped enclosure, the heat exchanger main body is constituted by a header pipe and a plurality of heat transfer pipes connected to the header pipe and disposed at predetermined intervals along a surface of a part of the header pipe, the header pipe has an area adjacent to an inner surface of the enclosure, and a seal section is provided between the inner surface of the enclosure and the area of the header pipe adjacent to the enclosure.

A heat exchanger includes a tank, spaced apart tubular elements, fins and a side cover. The tank receives a first heat exchange fluid therein. The spaced apart tubular elements defining a heat exchanger core are in fluid communication with the tank and enable heat exchange between a first heat exchange fluid flowing there through and a second heat exchange fluid flowing around and across the tubular elements. The fins arranged alternately with respect to the tubular elements promote heat exchange. The side cover adjacent to a lateral face of the heat exchanger core, covers and shields the lateral face and at least a portion of the heat exchanger core disposed between the tubular elements proximal to the lateral face of the heat exchanger core and the corresponding side cover.
