Title:
HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2021/124582
Kind Code:
A1
Abstract:
Provided is 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 two flow passages, i.e. a first flow passage 11 and a second flow passage 21, within a space formed between an inner cylinder 10 and an outer cylinder 20 which are concentric to each other. A spiral heat transfer body 41 is disposed between the inner cylinder 10 and the outer cylinder 20, and the spiral heat transfer body 41 has a cross-section shape that is substantially triangular in the axial-direction cross section. The space is partitioned into the first flow passage 11 and the second flow passage 21 by the spiral heat transfer body 41, and heat is exchanged via the spiral heat transfer body 41 between a first fluid F1 flowing within the first flow passage 11 and a fluid F2 flowing within the second flow passage 21.
