Document Type and Number:
WIPO Patent Application WO/2011/030530
Kind Code:
A1
Abstract:
Disclosed is a cylindrical heat exchanger which achieves an improvement in the rate of heat transfer from the heating surface of a heater to water and can rapidly discharge generated bubbles to the outside. Specifically disclosed is a cylindrical heat exchanger (7) provided with a casing (10), a cylindrical heater (20) housed in the casing, and a pole-shaped core member (30) provided in the heater (20), wherein in an inside cylindrical flow channel (45) and an outside cylindrical flow channel (47) which communicate with each other via a turnaround space (46), an inside helical guide (inside helical guide) (40) and an outside helical guide (outside helical guide) (41) are provided, respectively.
