Description

Technical Field

[0001] This utility model relates to the field of home appliance technology, and in particular to a baffle, a heat exchanger and a gas water heater. Background Technology

[0002] Existing forced draft gas water heaters typically have turbulence springs and sluices installed inside the heat exchange pipes of their heat exchangers. However, the turbulence effect of these springs and sluices is poor, and they still cannot fully exchange heat between the liquid and the heat exchange pipes. This can easily lead to localized high temperatures and bubbles, and with long-term use, the water tank may burn through, resulting in scale buildup and reduced heat exchange efficiency.

[0003] Therefore, a spoiler is urgently needed to solve the above problems. Utility Model Content
