HEAT EXCHANGER AND HEAT EXCHANGE SYSTEM

WIPO Patent Application WO/2015/059957

A1

Provided are a heat exchanger and a heat exchange system which have satisfactory heat exchange efficiency, enable a fluid passage to be cleaned and sterilize easily, and enable the conditions thereof to be confirmed easily. A heat exchanger is provided with a first flow passage-forming member (11, 13) having a container shape; and a flow passage-forming second member (12) disposed on the inside of the first flow passage forming member (11, 13) so that the flow passage-forming second member (12) is mountable and dismountable from the first flow passage-forming member (11, 13). The first flow passage-forming member (11, 13) of the heat exchanger (1) is configured in such a manner that: the diameter of the inner peripheral surface of the peripheral wall section of the container shape gradually decreases from the upper part toward the lower part; a first flow passage (134) through which heat exchange liquid flows is formed inside the peripheral wall section; and a helical second flow passage (114) through which liquid to be subjected to heat exchange flows is formed between the inner peripheral surface of the first flow passage-forming member (11, 13) and the outer peripheral surface of the flow passage-forming second member (12).
