Abstract
A burning heat exchange device for a gas water heater comprises a heat exchanger and a burner. The heat exchanger comprises a heat exchanger piece and a water guide pipe, one end of the water guide pipe is a cold water incoming end while the other end of the same is a hot water outgoing end, and the heat exchanger and the burner are matched. The burning heat exchange device is characterized in that the burner is an infrared burner, the heat exchanger and the burner are arranged oppositely in a front-rear manner, and a gap is formed between the heat exchanger and the burner. Due to adoption of the above structure, an infrared radiation plate is arranged, and flame is changed into infrared rays when gas is burnt; the infrared rays are directly irradiated on the heat exchanger and transmit heat, so that in the process of heating, heat energy loss is small, and heat efficiency is high.
