Abstract
A heat exchanger includes three flow paths, a first flow path, a second flow path, and a third flow path, which turn spirally in the space formed between an inner cylinder and an outer cylinder are provided. These flow paths are defined by an inner heat transfer body and an outer heat transfer body, and heat exchange is performed through the heat transfer bodies. The heat transfer bodies turn spirally, have a screw shape in an axial cross-sectional view, and are assembled into a screw shape. The flow path area of the first flow path is varied by changing the shapes of a male thread and a female thread, and the second flow path and the third flow path are formed in a spiral shape, allowing for exchange of heat through the heat transfer bodies.
