FLOW CHANNEL STRUCTURE OF HEAT EXCHANGER OF BOILER

摘要

A flow channel structure of a water passage of a heat exchanger in a boiler is provided to enhance heating efficiency by installing a flux controlling plate between a cap member and a heat exchange pipe. A flow channel structure of a water passage of a water passage of a heat exchanger in a boiler comprises a heat exchanger including a body casing, a side plate and a cap member(50). A heat exchanging pipe(20) is incorporated in the body casing. A side plate having an inlet and an outlet is installed at a side of the heat exchanging pipe. The cap member is formed at an outside of the inlet and the outlet in a symmetrical structure. A flux controlling plate(40) is installed between the side plate and the inlet and the outlet.
