<P>PROBLEM TO BE SOLVED: To provide a heat exchanger that is capable of preventing the generation and deposition of scale, and has a long life. <P>SOLUTION: The heat exchanger 10 has a lower part header section 45 including a header main channel 45a and a header throttling channel 45b in which a channel cross section narrows gradually and which is opened to a channel space 25. By this configuration, a flow rate in the header throttling channel 45b is gradually accelerated as going forward, so that air bubbles are not left along the way and are made to smoothly flow out. Accordingly, this configuration prevents the flow from being drifted by the bubbles, which inhibits a uniform heat exchange on a heat transfer surface, and thereby the heat exchanger having the long life can be provided by ensuring a stable heat exchange. <P>COPYRIGHT: (C)2013,JPO&INPIT |
