Abstract

The invention discloses a heat exchanger for a fuel water heater, comprising a heat exchanging housing, a heat absorbing sheet and a water pipe. The water pipe comprises a straight pipe, a U-shaped pipe and a coiling pipe; the straight pipe is sleeved in the heat absorbing sheet and is connected with the coiling pipe; the straight pipes are mutually communicated via the U-shaped pipe; at least two rows of water pipe holes are arranged on the heat absorbing sheet up and down based on the mounting and use direction; a plurality of turbulence bulges are arranged on heat absorbing sheet; the turbulence bulges are located above the water pipe holes at the lower rows of the heat absorbing sheet; the turbulence bulges can increase the air current disturbance so as to generate turbulence and reduce the speed of the air current passing through the coiling pipe so that the air current passing through the turbulence bulges and the cold water in the coiling pipe can be further executed heat exchanging, thereby effectively improving the heat exchanging rate; side overturning structures which are in the same direction with the turbulence bulges are arranged on the upper edge of the heat absorbing sheet at interval, thereby reducing the area of the air current outlet, changing the air current rising speed, implementing the secondary turbulence, and improving the heat exchanging efficiency.
