The utility model discloses a gas water heater component and a heat exchanger. The heat exchanger comprises a connection box, a heat exchange component, a pipe casing and a smoke exhaust pipe, wherein the upper end of the connection box is opened and is provided with an intake cavity and an exhaust cavity which are spaced with each other along the transverse direction, an air inlet communicated with the intake cavity is formed in the sidewall of the connection box, a smoke guide air flue, which stretches into a heat exchange cavity, is arranged on the air inlet, a water discharge port communicated with the bottom of the heat exchange cavity is formed in the lower end of the connection box, and the bottom of the heat exchange cavity is communicated with the bottom of the exhaust cavity; the heat exchange component is arranged in the heat exchange cavity; the pipe casing is arranged on the upper end of the connection box, and an exhaust channel communicated with the exhaust cavity and a partition board used for closing the upper end of the heat exchange cavity are arranged in the pipe casing; the smoke exhaust pipe is arranged on the upper end of the pipe casing and is closely connected to the exhaust channel. The heat exchanger provided by the utility model is simple in structure, through setting the smoke guide air flue, heat exchange flue gas enters a proper position in the heat exchange cavity, so that a flow direction of the flue gas in the heat exchange cavity is from top to bottom, the flow direction of the flue gas is the same as the dropping direction of condensed water condensed on the inner wall of the heat exchange cavity and the outer surface of the heat exchange component, so that the condensed water is prevented from blocking the heat exchanger.
