Classification: CPC F | IPC F

Claim 9:
10. A flow path member for a heat exchanger, comprising:
an inner cylinder capable of housing a heat recovery member through which a first fluid can flow;
an outer cylinder having a feed port capable of feeding a second fluid and a discharge port capable of discharging the second fluid, the outer cylinder being disposed so as to be spaced on a radially outer side of the inner cylinder such that a flow path for the second fluid is formed between the outer cylinder and the inner cylinder;
a feed pipe connected to the feed port; and
a discharge pipe connected to the discharge port,
wherein the feed port and the discharge port are provided so as to be located in a distance of less than half the circumference of the outer cylinder in a circumferential direction,
wherein the feed port and the discharge port are located on the same circumference of the outer cylinder,
wherein the flow path member comprises at least one of a flow path resistance increasing structure portion provided at the flow path for the second fluid on a shorter circumference side between the feed port and the discharge port, and a flow path resistance increasing member provided at the flow path for the second fluid on the shorter circumference side between the feed port and the discharge port, and
wherein the feed pipe and the discharge pipe are connected to the feed port and discharge port, respectively, without intruding into the second flow path.
