Title:
HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2014/171095
Kind Code:
A1
Abstract:
A heat exchanger is configured so that heat exchange tubes are compact and so that the loss of pressure of fluid flowing through external flow passages formed between adjacent heat exchange tubes is reduced. The first protrusions (41) and second protrusions (42) of first heat exchange tubes (2A) are joined to portions of second heat exchange tubes (2B), the portions being located around the inlets (3C) and outlets (3D) thereof.
The first flow passage forming section (61), second flow passage forming section (62), and third flow passage forming section (63) of the internal flow passages (3) of both a first heat exchange tube (2A) and a second heat exchange tube (2B) face the first thin walled sections (21A) and second thin walled sections (21B) of both the second heat exchange tube (2B) and the first heat exchange tube (2A) with an external flow passage (4) therebetween. The first flow passage forming section (61), second flow passage forming section (62), and third flow passage forming section (63) of the first heat exchange tube (2A) and the first flow passage forming section (61), second flow passage forming section (62), and third flow passage forming section (63) of the second heat exchange tubes (2B) are arranged in a staggered pattern in the width direction of heat exchange tubes (2).
